Rencontre avec les français DBpédiens à Lyon
In cooperation with Thomas Riechert (HTWK/InfAI), the DBpedia Association organized our second DBpedia meetup this year, this time in Lyon. On July 3rd, 2018, we met the French DBpedia Community at the ENS in person and presented the vision of the new DBpedia Databus, an opportunity which simplifies the work with data.
First and foremost, we would like to thank the Institute for Applied Informatics for supporting our community and the LARHRA Laboratory as well as the ENS for hosting our community meetup. Special thanks go to Thomas Riechert and Vincent Alamercery (LARHRA Lyon) for organizing the event.
Sebastian Hellmann (AKSW/KILT) opened up the meetup in Lyon by introducing the DBpedia development strategy and the new DBpedia Databus to the French DBpedia community (slides). Afterwards, Elmahdi Korfed from INRIA presented new features and tools as results developed in the French DBpedia chapter (slides):
In the following months, Elmahdi plans to work on the DBpedia historic live version and the DBpedia wiki commons. His research will be presented during our 12th DBpedia Community meeting on September 10th, in Vienna.
Following Elmahdi, Francesco Beretta presented LARHRA laboratory and its different research areas. In particular, he introduced the Data for History Consortium which is an international consortium founded in 2017 with the aim of improving geo-historical data interoperability in the semantic web.
The afternoon track started out with an inspiring presentation by Adam Sanchez from the University of Grenoble. He talked about ‘RDFization of a relational database from medicine domain using Ontop’ (slides) and introduced the Ontop mappings. Afterwards, Oscar Rodríguez Rocha (University of Côte d’Azur) showcased the application ‘Automatic Generation Educational Quizzes’ from DBpedia (slides) and explained how the automatic generation of quizzes works based on the game Les Incollables.
The meeting concluded with a dynamic discussion on the DBpedia Databus and potential collaborations between the DBpedia Association and the French DBpedia Chapter.
You still can’t get enough of DBpedia?
Don’t worry, we already have another meeting of the DBpedia community in the pipeline. Our 12th DBpedia Community meeting is scheduled for September 10th and preparations on the program are already in full swing. Our DBpedia Day will kick-off this year’s edition of SEMANTiCS 2018, hosted at TU Vienna and brings the European DBpedia community together.
You want to contribute? Please submit your proposal and be a part of our amazing program. Register here and meet us and other DBpedia enthusiasts in Vienna. We are looking forward to your contribution.
See you soon!

Unfortunately, with the new GDPR, we experienced some trouble with our Blog. That is why this post is published a little later than anticipated.
There you go.
With our new strategic orientation and the emergence of the DBpedia Databus, we wanted to meet some DBpedia enthusiasts of the German DBpedia Community.
The recently hosted 6th LSWT (Leipzig Semantic Web Day) on June 18th, was the perfect platform for DBpedia to meet with researchers, industry and other organizations to discuss current and future developments of the semantic web.
Under the motto “Linked Enterprises Data Services”, experts in academia and industry talked about the interlinking of open and commercial data of various domains such as e-commerce, e-government, and digital humanities.
Sören Auer, DBpedia endorser and board member as well as director of TIB, the German National Library of Science and Technology, opened the event with an exciting keynote. Recapping the evolution of the semantic and giving a glimpse into the future of integrating more cognitive processes into the study of data, he highlighted the importance of AI, deep learning, and machine learning. They are as well as cognitive data, no longer in their early stages but advanced to fully grown up sciences.
Shortly after, Sebastian Hellmann, director of the DBpedia Association, presented the new face of DBpedia as a global open knowledge network. DBpedia is not just the most successful open knowledge graph so far, but also has a deep inside knowledge about all connected open knowledge graphs (OKG) and how they are governed.
With our new credo connecting data is about linking people and organizations, the global DBpedia platform aims at sharing efforts of OKG governance, collaboration, and curation to maximize societal value and develop a linked data economy.
The DBpedia Databus functions as Metadata Subscription Repository, a platform that allows exchanging, curate and access data between multiple stakeholders. In order to maximize the potential of your data, data owners need a WebID to sign their Metadata with a private key in order to make use of the full Databus services. Instead of one huge monolithic release every 12 months the Databus enables easier contributions and hence partial releases (core, mapping, wikidata, text, reference extraction) at their own speed but in much shorter intervals (monthly). Uploading data on the databus means connecting and comparing your data to the network. We will offer storage services, free & freemium services as well as data-as-a-service. A first demo is available via http://downloads.dbpedia.org/databus
During the lunch break, LSWT participants had time to check out the poster presentations. 4 of the 18 posters used DBpedia as a source. One of them was Birdory, a memory game developed during the Coding Da Vinci hackathon, that started in April 2018. Moreover, other posters also used the DBpedia vocabulary.
In the afternoon, participants of LSWT2018 joined hands-on tutorials on SPARQL and WebID. During the SPARQL tutorial, ten participants learned about the different query types, graph patterns, filters, and functions as well as how to construct SPARQL queries step by step with the help of a funny Monty Python example.
Afterwards, DBpedia hosted a hands-on workshop on WebID, the password-free authentication method using semantics. The workshop aimed at enabling participants to set up a public/private key, a certificate, and a WebID. Everything they needed to bring was a laptop and an own webspace. Supervised by DBpedia’s executive director Dr. Sebastian Hellmann and developer Jan Forberg, people had to log-into a test web service at the end of the session, to see if everything worked out. All participants seemed well satisfied with the workshop – even if not everyone could finish it successfully they got a lot of individual help and many hints. For support purposes, DBpedia will stay close in touch with those participants.
We are currently looking forward to our next DBpedia meetup in Lyon, France on July 3rd and the DBpedia Day co-located with Semantics 2018 in Vienna. Contributions to both events are still welcome. Send your inquiry to email@example.com.

Working with data is hard and repetitive. That is why we are more than happy to announce the launch of the alpha version of our DBpedia Databus, a way that simplifies working with data.
We have studied the data network for already 10 years and we conclude that organizations with open data are struggling to work together properly. Even though they could and should collaborate, they are hindered by technical and organizational barriers. They duplicate work on the same data. On the other hand, companies selling data cannot do so in a scalable way. The consumers are left empty-handed and trapped between the choice of inferior open data or buying from a jungle-like market.
We need to rethink the incentives for linking data
We envision a hub, where everybody uploads data. In that hub, useful operations like versioning, cleaning, transformation, mapping, linking, merging, hosting are done automagically on a central communication system, the bus, and then again dispersed in a decentral network to the consumers and applications. On the Databus, data flows from data producers through the platform to the consumers (left to right), any errors or feedback flows in the opposite direction and reaches the data source to provide a continuous integration service and improves the data at the source.
The DBpedia Databus is a platform that allows exchanging, curating and accessing data between multiple stakeholders. Any data entering the bus will be versioned, cleaned, mapped, linked and its licenses and provenance tracked. Hosting in multiple formats will be provided to access the data either as dump download or as API.
Publishing data on the Databus means connecting and comparing your data to the network
If you are grinding your teeth about how to publish data on the web, you can just use the Databus to do so. Data loaded on the bus will be highly visible, available and queryable. You should think of it as a service:
- Visibility guarantees, that your citations and reputation goes up.
- Besides a web download, we can also provide a Linked Data interface, SPARQL-endpoint, Lookup (autocomplete) or other means of availability (like AWS or Docker images).
- Any distribution we are doing will funnel feedback and collaboration opportunities your way to improve your dataset and your internal data quality.
- You will receive an enriched dataset, which is connected and complemented with any other available data (see the same folder names in data and fusion folders).
How it works at the moment
Integration of data is easy with the Databus. We have been integrating and loading additional datasets alongside DBpedia for the world to query. Popular datasets are ICD10 (medical data) and organizations and persons. We are still in an initial state, but we already loaded 10 datasets (6 from DBpedia, 4 external) on the bus using these phases:
- Acquisition: data is downloaded from the source and logged in.
- Conversion: data is converted to N-Triples and cleaned (Syntax parsing, datatype validation, and SHACL).
- Mapping: the vocabulary is mapped on the DBpedia Ontology and converted (We have been doing this for Wikipedia’s Infoboxes and Wikidata, but now we do it for other datasets as well).
- Linking: Links are mainly collected from the sources, cleaned and enriched.
- IDying: All entities found are given a new Databus ID for tracking.
- Clustering: ID’s are merged onto clusters using one of the Databus ID’s as cluster representative.
- Data Comparison: Each dataset is compared with all other datasets. We have an algorithm that decides on the best value, but the main goal here is transparency, i.e. to see which data value was chosen and how it compares to the other sources.
- A main knowledge graph fused from all the sources, i.e. a transparent aggregate.
- For each source, we are producing a local fused version called the “Databus Complement”. This is a major feedback mechanism for all data providers, where they can see what data they are missing, what data differs in other sources and what links are available for their IDs.
- You can compare all data via a web service.
Contact us via firstname.lastname@example.org if you would like to have additional datasets integrated and maintained alongside DBpedia.
From your point of view
If you are selling data, the Databus provides numerous opportunities for you. You can link your offering to the open entities in the Databus. This allows consumers to discover your services better by showing it with each request.
Open data on the Databus will be a commodity. We are greatly downing the cost of understanding the data, retrieving and reformatting it. We are constantly extending ways of using the data and are willing to implement any formats and APIs you need. If you are lacking a certain kind of data, we can also scout for it and load it onto the Databus.
Is it free?
Maintaining the Databus is a lot of work and servers incurring a high cost. As a rule of thumb, we are providing everything for free that we can afford to provide for free. DBpedia was providing everything for free in the past, but this is not a healthy model, as we can neither maintain quality properly nor grow.
On the Databus everything is provided “As is” without any guarantees or warranty. Improvements can be done by the volunteer community. The DBpedia Association will provide a business interface to allow guarantees, major improvements, stable maintenance, and hosting.
Final databases are licensed under ODC-By. This covers our work on recomposition of data. Each fact is individually licensed, e.g. Wikipedia abstracts are CC-BY-SA, some are CC-BY-NC, some are copyrighted. This means that data is available for research, informational and educational purposes. We recommend to contact us for any professional use of the data (clearing) so we can guarantee that legal matters are handled correctly. Otherwise, professional use is at own risk.
The Databus data is available at http://downloads.dbpedia.org/databus/ ordered into three main folders:
- Data: the data that is loaded on the Databus at the moment
- Global: a folder that contains provenance data and the mappings to the new IDs
- Fusion: the output of the Databus
Most notably you can find:
- Provenance mapping of the new ids in global/persistence-core/cluster-iri-provenance-ntriples/<http://downloads.dbpedia.org/databus/global/persistence-core/cluster-iri... and global/persistence-core/global-ids-ntriples/<http://downloads.dbpedia.org/databus/global/persistence-core/global-ids-...
- The final fused version for the core: fusion/core/fused/<http://downloads.dbpedia.org/databus/fusion/core/fused/>
- A detailed JSON-LD file for data comparison: fusion/core/json/<http://downloads.dbpedia.org/databus/fusion/core/json/>
- Complements, i.e. the enriched Dutch DBpedia Version: fusion/core/nl.dbpedia.org/<http://downloads.dbpedia.org/databus/fusion/core/nl.dbpedia.org/>
(Note that the file and folder structure are still subject to change)
- Include more existing data from DBpedia
- Renew all DBpedia releases in a separate fashion:
- Load all data in the comparison tool: http://184.108.40.206:9000/?s=http%3A%2F%2Fid.dbpedia.org%2Fglobal%2F12HpzV&p=http%3A%2F%2Fdbpedia.org%2Fontology%2Farchitect&src=general
- Load all data into a SPARQL endpoint
- Create a simple open source software that let’s everybody push data on the Databus in an automated way
- build your own data inventory and merchandise your data via Linked Data or via secure named graphs in the DBpedia SPARQL Endpoint (WebID + TLS + OpenLink’s Virtuoso database)
- Offer your Linked Data tools, services, products
- Incubate new research into products
- Example: Support for RDFUnit (https://github.com/AKSW/RDFUnit created by the SHACL editor), assistance with SHACL writing and deployment of the open-source software
DBpedia and the Databus will transform Linked Data into a networked data economy

Supporting young and aspiring developers has always been part of DBpedia‘s philosophy. Through various internships and collaborations with programmes such as Google Summer of Code, we were able to not only meet aspiring developers but also establish long-lasting relationships with these DBpedians ensuring a sustainable progress for and with DBpedia. For 6 years now, we have been part of Google Summer of Code, one of our favorite programmes. This year, we are also taking part in Coding da Vinci, a German-based cultural data hackathon, where we support young hackers, coders and smart minds with DBpedia datasets.
DBpedia at Google Summer of Code 2018
This year, DBpedia will participate for the sixth time in a row in the Google Summer of Code program (GSoC). Together with our amazing mentors, we drafted 9 project ideas which GSOC applicants could apply to. Since March 12th, we received many proposal drafts out of which 12 final projects proposals have been submitted. Competition is very high as student slots are always limited. Our DBpedia mentors were critically reviewing all proposals for their potential and for allocating them one of the rare open slots in the GSoC program. Finally, on Monday, April 23rd, our 6 finalists have been announced. We are very proud and looking forward to the upcoming months of coding. The following projects have been accepted and will hopefully be realized during the summer.
- A Neural QA Model for DBpedia (Aman Mehta)
- A Neural QA Model for DBpedia (Tarun S R)
- Complex Embeddings for OOV Entities ( Bharat Suri)
- Fusing the List Extractor and the Table Extractor(Sachin Malepali)
- Table of Content Extractor (Hrishikesh Singh)
- Web application to detect incorrect mappings across DBpedias in different languages (Víctor Fernández Rico)
Our gang of DBpedia mentors comprises of very experienced developers that are working with us on this project for several years now. Speaking of sustainability, we also have former GSoC students on board, who get the chance to mentor projects building on ideas of past GSoC’s. And while students and mentors start bonding, we are really looking forward to the upcoming months of coding – may it be inspiring, fun and fruitful.
As already mentioned in the previous newsletter, DBpedia is part of the CodingDaVinciOst 2018. Founded in Berlin in 2014, Coding da Vinci is a platform for cultural heritage institutions and the hacker, developer, designer, and gamer community to jointly develop new creative applications from cultural open data during a series of hackathon events. In this year’s edition, DBpedia provides its datasets to support more than 30 cultural institutions, enriching their datasets in order participants of the hackathon can make the most out of the data. Among the participating cultural institutions are, for example, the university libraries of Chemnitz, Jena, Halle, Freiberg, Dresden and Leipzig as well as the Sächsisches Staatsarchiv, Museum für Druckkunst Leipzig, Museum für Naturkunde Berlin, Duchess Anna Amalia Library, and the Museum Burg Posterstein.
CodingDaVinciOst 2018, the current edition of the hackathon, hosted a kick-off weekend at the Bibliotheca Albertina, the University Library in Leipzig. During the event, DBpedia offered a hands-on workshop for newbies and interested hackathon participants who wanted to learn about how to enrich their project ideas with DBpedia or how to solve potential problems in their projects with DBpedia.
We are now looking forward to the upcoming weeks of coding and hacking and can’t wait to see the results on June 18th, when the final projects will be presented and awarded. We wish all the coders and hackers a pleasant and happy hacking time. Check our DBpedia Twitter for updates and latest news.

DBpedia is part of a large network of industry and academia, companies, and organizations as well as 20 Universities including student members. Our aim is to qualify aspiring developers and knowledge graph enthusiasts by working together with industry partners on DBpedia-related tasks. The final goal is, that DBpedia can be effectively integrated into organizations and businesses and incubate their knowledge graph to the next level. We intend to foster collaboration between DBpedia and organizations sharing an interest in and want to profit from Open-Knowledge-Graph governance.
Therefore we have developed an internship and mentoring program to:
- qualify a motivated student and beginner level developer. He/she learns about DBpedia, your organization, and data. Collaborative coaching may qualify intern for hiring.
- move your organization’s data space closer to DBpedia. Internship goals are defined by DBpedia mentors and your organization and focus on concrete needs of your business.
- gain insight into your needs helping us to shape our strategy for the future.
Springer Nature was the first partner we collaborated with, in of our new program. We set out on an endeavor to interlink Springer Nature’s SciGraph and DBpedia datasets.
With Beyza Yaman, who managed to prevail against 7 other international competitors, we found the perfect partner in crime to tackle this challenge. Read her interview below and find out more about the internship.
Who are you?
My name is Beyza Yaman and I am a Ph.D. student in the Department of Computer Science and Engineering (DIBRIS) at University of Genoa (Italy). I am working on the problem of source selection on Linked Open Data for live queries proposing a context and quality dependent solution. Beside my studies, I like to meet new people, learn their cultures and discover new places, especially by walking/hiking events.
Why DBpedia? What is your main interest in DBpedia and what was your motivation to apply for our collaborative internship?
I have already been using DBpedia datasets for my experiments. Besides from being the core of the Linked Data Cloud, DBpedia is one of the platforms which brings the applied semantic technologies forward and ahead of most other data technologies. Also, collaboration with Springer Nature which is one of the best publishing companies was the cherry on the cake! Springer is an innovative company which applies the latest technologies to their requirements. Thus, being involved in a project with different grounds seemed to be a fruitful experience. When I saw the announcement of the internship, I thought this is a great opportunity not to be missed!
What have you been responsible for?
My tasks during the internship had been
- Link discovery between SciGraph and DBpedia datasets
- Text mining of DBpedia entities from Springer Nature publication content
- Create useful linkset-files for the resulting links
As the web of data is growing into the interlinked data space, data sources should be connected to discover further insight from the data by creating meaningful relations. Moreover, further information (e.g. quality) about these link sets forms another aspect of the Semantic Web objectives. Thus, we worked on interlinking SciGraph and DBpedia datasets by using the Link Discovery approach for the structured content and the Named Entity Recognition approach for unstructured text. We were able to integrate SciGraph data with DBpedia resources which improves the identity resolution in the existing resources and to enrich the SciGraph data with additional relations by annotating SciGraph content with DBpedia links which increases the discoverability of the data. One of the challenges we faced was having a huge amount of data and, actually, we have produced even more for the Linked Data users. You can follow our work, use the data and give us feedback from this repository (https://github.com/dbpedia/sci-graph-links).
What did you learn from the project?
It has been a fantastic experience which helped me to expand my theoretical knowledge with a lot of practical aspects. I worked with Markus Freudenberg from DBpedia and Tony Hammond, Michele Pasin and Evangelos Theodoridis from Springer Nature. Working with technically well-equipped researchers and professionals on the subject has been very influential for my research. Especially, working with a team of academics and professionals in collaboration has taught me two different views of looking at the project. I learned more about SciGraph data and DBpedia, as well as, many ways of dealing with huge amount of data, tools used in DBpedia and Linked Data environment, the importance of open source data/codes. Besides the project, I had a chance to witness development phases of DBpedia in the Knowledge Integration and Linked Data Technologies (KILT) group (Leipzig) with a bunch of cool guys and girls who made my stay more enjoyable. I also met a lot of researchers with Semantic Web experience which has extended my point of view widely.
What are your next plans? How do you want to contribute to DBpedia in the future?
I would like to finish my Ph.D. and extend my knowledge by involving new exciting projects like this one. Publishing what we have done and further quality improvements might be a nice follow up for the work and Linked Data community. Besides, I would like to contribute to the development of the Turkish DBpedia Chapter which is unfortunately missing. Thus, in this way, we can promote the usage and development of DBpedia and Linked Data to the Turkish research community and companies as well.
There will also be a report on the collaboration between Springer Nature and DBpedia that will cover the technical details of linking DBpedia and SciGraph datasets. We will keep you informed about news via Twitter and our Website.
We are really happy to have worked with her and we are now looking forward to a Turkish DBpedia Chapter. If you are a DBpedia enthusiast and want to help to start the Turkish DBpedia chapter, just get in touch with Beyza or contact us.
Did her story inspire you? Do you want to become an intern at DBpedia? Check our Website, Twitter, and Social Media and don’t miss any internship updates.
Last but not least, we like to thank Springer Nature for their cooperation and commitment to the project.
In case you like to collaborate with us in order to find a developer that helps to integrate DBpedia into your business get in touch with us via email@example.com.

Just recently, DBpedia Association member and hosting specialist, OpenLink released the DBpedia Usage report, a periodic report on the DBpedia SPARQL endpoint and associated Linked Data deployment.
The report not only gives some historical insight into DBpedia’s usage, number of visits and hits per day but especially shows statistics collected between October 2016 and December 2017. The report covers more than a year of logs from the DBpedia web service operated by OpenLink Software at http://dbpedia.org/sparql/.
Before we want to highlight a few aspects of DBpedia’s usage we would like to thank Open Link for the continuous hosting of the DBpedia Endpoint and the creation of this report
Speaking of which, as you can see in the following tables, there has been a massive increase in the number of hits coinciding with the DBpedia 2015–10 release on April 1st, 2016.
This boost can be attributed to an intensive promotion of DBpedia via community meetings, communication with various partners in the Linked Data community and Social media presence among the community, in order to increase backlinks.
Since then, not only the numbers of hits increased but DBpedia also provided for better data quality. We are constantly working on improving accessibility, data quality and stability of the SPARQL endpoint. Kudos to Open Link for maintaining the technical baseline for DBpedia.
The full report is available here.
Thanks for reading and keep using DBpedia!

Can you believe ..?
… that it has already been eleven years since the first DBpedia dataset was released? Eleven years of development, improvements and growth, and now, 13 billion pieces of information are comprised in our last DBpedia release. We want to take this opportunity to send out a big thank you to all contributors, developers, coders, hosters, funders, believers and DBpedia enthusiasts who made that possible. Thank you for your support.
But, apart from our data sets, there is much more DBpedia has been doing., especially during the past year. Think about the success story of Wouter Maroy, a GSoC 2016 student who got the opportunity to do a six weeks internship at our DBpedia office in Leipzig and who is still contributing to DBpedia’s progress.
All in all, 2017 was highly successful and full of exciting events. Remember our 10th DBpedia Community Meeting in Amsterdam featuring an inspiring keynote by Dr. Chris Welty, one of the developers at IBM computer Watson. Our DBpedia meetings are always a great way to bring the community closer together, and to not only meet our DBpedia audience but also new faces. Therefore, we have already started to plan our community meetings for 2018.
We hope to see you in Poznan, Poland, in spring and to meet you during the SEMANTiCS Conference in Vienna, from 10th – 13th of September 2018. Additionally, if everything goes according to plan, we will be mentoring young DBpedia enthusiasts throughout summer in GSoC 2018 and meet the US DBpedia community in autumn this year. Follow us on Twitter or check our Website for the latest News.
And last but not least, this year we plan something special. DBpedia intends to participate in Coding DaVinci – Germany’s first open cultural hackathon, which happens to take place in Leipzig, right around the corner. Aspiring data enthusiast will develop new creative applications from cultural open data. The kick-off is in early April, followed by 9 weeks of cooperative coding. We are eagerly awaiting the start of this event.
We do hope, we will meet you and some new faces during our events this year. The DBpedia Association want to get to know you because DBpedia is a community effort and would not continue to develop, improve and grow without you. Thank you and see you soon…

One lightning event after the other. Just four weeks after our Amsterdam Community Meeting, we crossed the Atlantic for the third time to meet with over 110 US-based DBpedia enthusiasts. This time, the DBpedia Community met in Cupertino, California and was hosted at Apple Inc.
First and foremost, we would like to thank Apple for the warm welcome and the hosting of the event.
After a Meet & Greet with refreshments, Taylor Rhyne, Eng. Product Manager at Apple, and Pablo N. Mendes, Researcher at Apple and chair of the DBpedia Community Committee, opened the main event with a short introduction setting the tone for the following 2 hours.
The main event attracted attendees with eleven invited talks from major companies of the Bay Area actively using DBpedia or interested in knowledge graphs in general such as Diffbot, IBM, Wikimedia, NTENT, Nuance, Volley and Stardog Union.
Tommaso Soru (University of Leipzig), DBpedia mentor in our Google Summer of Code (GSoC) projects, opened the invited talks session with the updates from the DBpedia developer community. This year, DBpedia participated in the GSoC 2017 program with 7 different projects including “First Chatbot for DBpedia”, which was selected as Best DBpedia GSoC Project 2017. His presentation is available here.

Invited Talks- A Short Recap
Filipe Mesquita (Diffbot) introduced the new DBpedia NLP Department, born from a recent partnership between our organization and the California based company, which aims at creating the most accurate and comprehensive database of human knowledge. His presentation is available here. Dan Gruhl (IBM Research) held a presentation about the in-house development of an omnilingual ontology and how DBpedia data supported this
endeavor. Stas Malyshev representative for Dario Taraborelli (both Wikimedia Foundation) presented the current state of the structured data initiatives at Wikidata and the query capabilities for Wikidata. Their slides are available here and here. Ricardo Baeza-Yates (NTENT) gave a short talk on mobile semantic search.
The second part of the event saw Peter F. Patel-Schneider (Nuance) holding a presentation with the title “DBpedia from the Fringe” giving some insights on how DBpedia could be further improved. Shortly after, Sebastian Hellmann, Executive Director of the DBpedia Association, walked the stage and presented the state of the art of the association, including achievements and future goals. Sanjay Krishnan (U.C. Berkeley) talked about the link between AlphaGo and data cleansing. You can find his slides here. Bill Andersen (Volley.com) argued for the use of extremely precise and fine-grained approaches to deal with small data. His presentation is available here. Finally, Michael Grove (Stardog Union) stressed on the view of knowledge graphs as knowledge toolkits backed by a graph data model.
The event concluded with refreshments, snacks and drinks served in the atrium allowing to talk about the presented topics, discuss the latest developments in the field of knowledge graphs and network between all participants. In the end, this closing session was way longer than had been planned.
GSoC Mentor Summit
Shortly after the CA Community Meeting, our DBpedia mentors Tommaso Soru and Magnus Knuth participated at the Google Summer of Code Mentor Summit held in Sunnyvale California. During free sessions hosted by mentors of diverse open source organizations, Tommaso and Magnus presented selected projects during their lightning talks. Beyond open source, open data topics have been targeted in multiple sessions, as this is not only relevant for research, but there is also a strong need in software projects. The meetings paved the way for new collaborations in various areas, e.g. the field of question answering over the DBpedia knowledge corpus, in particular the use of Neural SPARQL Machines for the translation of natural language into structured queries. We expect that this hot deep-learning topic will be featured in the next edition of GSoC projects. Overall, it has been a great experience to meet so many open source fellows from all over the world.
