A year with DBpedia – Retrospective Part Two

Retrospective Part II. Welcome to the second part of our journey around the world with DBpedia. This time we are taking you to Greece, Germany, to Australia and finally France.

Let the travels begin.

Welcome to Thessaloniki, Greece & ESWC

DBpedians from the Portuguese Chapter presented their research results during ESWC 2018 in Thessaloniki, Greece.  the team around Diego Moussalem developed a demo to extend MAG  to support Entity Linking in 40 different languages. A special focus was put on low-resources languages such as Ukrainian, Greek, Hungarian, Croatian, Portuguese, Japanese and Korean. The demo relies on online web services which allow for an easy access to (their) entity linking approaches. Furthermore, it can disambiguate against DBpedia and Wikidata. Currently, MAG is used in diverse projects and has been used largely by the Semantic Web community. Check the demo via http://bit.ly/2RWgQ2M. Further information about the development can be found in a research paper, available here

 

Welcome back to Leipzig Germany

With our new credo “connecting data is about linking people and organizations”, halfway through 2018, we finalized our concept of the DBpedia Databus. This global DBpedia platform aims at sharing the efforts of OKG governance, collaboration, and curation to maximize societal value and develop a linked data economy.

With this new strategy, we wanted to meet some DBpedia enthusiasts of the German DBpedia Community. Fortunately, the LSWT (Leipzig Semantic Web Tag) 2018 hosted in Leipzig, home to the DBpedia Association proofed to be the right opportunity.  It was the perfect platform to exchange with researchers, industry and other organizations about current developments and future application of the DBpedia Databus. Apart from hosting a hands-on DBpedia workshop for newbies we also organized a well-received WebID -Tutorial. Finally,  the event gave us the opportunity to position the new DBpedia Databus as a global open knowledge network that aims at providing unified and global access to knowledge (graphs).

Welcome down under – Melbourne Australia

Further research results that rely on DBpedia were presented during ACL2018, in Melbourne, Australia, July 15th to 20th, 2018. The core of the research was DBpedia data, based on the WebNLG corpus, a challenge where participants automatically converted non-linguistic data from the Semantic Web into a textual format. Later on, the data was used to train a neural network model for generating referring expressions of a given entity. For example, if Jane Doe is a person’s official name, the referring expression of that person would be “Jane”, “Ms Doe”, “J. Doe”, or  “the blonde woman from the USA” etc.

If you want to dig deeper but missed ACL this year, the paper is available here.

 

Welcome to Lyon, France

In July the DBpedia Association travelled to France. With the organizational support of Thomas Riechert (HTWK, InfAI) and Inria, we finally met the French DBpedia Community in person and presented the DBpedia Databus. Additionally, we got to meet the French DBpedia Chapter, researchers and developers around Oscar Rodríguez Rocha and Catherine Faron Zucker.  They presented current research results revolving around an approach to automate the generation of educational quizzes from DBpedia. They wanted to provide a useful tool to be applied in the French educational system, that:

  • helps to test and evaluate the knowledge acquired by learners and…
  • supports lifelong learning on various topics or subjects. 

The French DBpedia team followed a 4-step approach:

  1. Quizzes are first formalized with Semantic Web standards: questions are represented as SPARQL queries and answers as RDF graphs.
  2. Natural language questions, answers and distractors are generated from this formalization.
  3. We defined different strategies to extract multiple choice questions, correct answers and distractors from DBpedia.
  4. We defined a measure of the information content of the elements of an ontology, and of the set of questions contained in a quiz.

Oscar R. Rocha and Catherine F. Zucker also published a paper explaining the detailed approach to automatically generate quizzes from DBpedia according to official French educational standards. 

 

 

Thank you to all DBpedia enthusiasts that we met during our journey. A big thanks to

With this journey from Europe to Australia and back we provided you with insights into research based on DBpedia as well as a glimpse into the French DBpedia Chapter. In our final part of the journey coming up next week, we will take you to Vienna,  San Francisco and London.  In the meantime, stay tuned and visit our Twitter channel or subscribe to our DBpedia Newsletter.

 

Have a great week.

Retrospective: GSoC 2018

With all the beta-testing, the evaluations of the community survey part I and part II and the preparations for the Semantics 2018 we lost almost sight of telling you about the final results of GSoC 2018. Following we present you a short recap of this year’s students and projects that made it to the finishing line of GSoC 2018.

 

Et Voilà

We started out with six students that committed to GSoC projects. However, in the course of the summer, some dropped out or did not pass the midterm evaluation. In the end, we had three finalists that made it through the program.

Meet Bharat Suri

… who worked on “Complex Embeddings for OOV Entities”. The aim of this project was to enhance the DBpedia Knowledge Base by enabling the model to learn from the corpus and generate embeddings for different entities, such as classes, instances and properties.  His code is available in his GitHub repository. Tommaso Soru, Thiago Galery and Peng Xu supported Bharat throughout the summer as his DBpedia mentors.

Meet Victor Fernandez

.. who worked on a “Web application to detect incorrect mappings across DBpedia’s in different languages”. The aim of his project was to create a web application and API to aid in automatically detecting inaccurate DBpedia mappings. The mappings for each language are often not aligned, causing inconsistencies in the quality of the RDF generated. The final code of this project is available in Victor’s repository on GitHub. He was mentored by Mariano Rico and Nandana Mihindukulasooriya.

Meet Aman Mehta

.. whose project aimed at building a model which allows users to query DBpedia directly using natural language without the need to have any previous experience in SPARQL. His task was to train a Sequence-2-Sequence Neural Network model to translate any Natural Language Query (NLQ) into the corresponding sentence encoding SPARQL query. See the results of this project in Aman’s GitHub repositoryTommaso Soru and Ricardo Usbeck were his DBpedia mentors during the summer.

Finally, these projects will contribute to an overall development of DBpedia. We are very satisfied with the contributions and results our students produced.  Furthermore, we like to genuinely thank all students and mentors for their effort. We hope to be in touch and see a few faces again next year.

A special thanks goes out to all mentors and students whose projects did not make it through.

GSoC Mentor Summit

Now it is the mentors’ turn to take part in this year GSoC mentor summit, October 12th till 14th. This year, Mariano Rico and Thiago Galery will represent DBpedia at the event. Their task is to engage in a vital discussion about this years program, about lessons learned, highlights and drawbacks they experienced during the summer. Hopefully, they return with new ideas from the exchange with mentors from other open source projects. In turn, we hope to improve our part of the program for students and mentors.

Sit tight, follow us on Twitter and we will update you about the event soon.

Yours DBpedia Association

French DBpedia enthusiasts joined the meetup in Lyon.

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.

Opening Session

Sebastian Hellmann opened up the meetup in Lyon.

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.

Elmahdi Korfed from INRIA presented new features developed in the French DBpedia chapter.

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.

Afternoon Track

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.

DBpedia at LSWT 2018

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.

Afternoon Session

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.

 

Thanks to Institut für Angewandte Informatik as well to the LEDS -project and eccenca for organizing LSWT2018 and keeping the local semantic web community thriving.

 

Upcoming Events:

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 dbpedia@infai.org.

DBpedia supports young developers

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.

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.  

 

DBpedia @ Coding da Vinci 2018

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.

To the DBpedia Community!

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…

Meeting with the US-DBpedians – A Wrap-Up

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. 

Main Event

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

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. 

DBpedia likes to thank the following poeple for organizinga nd hosting our Community Meeting in Cupertino, California.

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.

Michael Grove – Stardog Union

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.

Upcoming events
