A year with DBpedia – Retrospective Part 2/2020

This is the final part of our journey through 2020. In the previous blog post we already presented DBpedia highlights, events and tutorials. Now we want to take a deeper look at the second half of 2020 and give an outlook for 2021.

DBpedia Autumn Hackathon and the KGiA Conference

From September 21st to October 1st, 2020 we organized the first Autumn Hackathon. We invited all community members to join and contribute to this new format. You had the chance to experience the latest technology provided by the DBpedia Association members. We hosted special member tracks, a Dutch National Knowledge Graph Track and a track to improve DBpedia. Results were presented at the final hackathon event on October 5, 2020. We uploaded all contributions on our Youtube channel. Many thanks for all your contributions and invested time!

The Knowledge Graphs in Action event

Chairs open the KGiA event on October 6, 2020.
Opening the KGiA event

The SEMANTiCS Onsite Conference 2020 had to be postponed till September 2021. To bridge the gap until 2021, we took the opportunity to organize the Knowledge Graphs in Action online track as a SEMANTiCS satellite event on October 6, 2020. This new online conference is a combination of two existing events: the DBpedia Community Meeting, which is regularly held as part of the SEMANTiCS, and the annual Spatial Linked Data conference organised by EuroSDR and the Platform Linked Data Netherlands. We glued it together and as a bonus we added a track about Geo-information Integration organized by EuroSDR. As special joint sessions we presented four keynote speakers. More than 130 knowledge graph enthusiasts joined the KGiA event and it was a great success for the organizing team. Do you miss the event? No problem! We uploaded all recorded sessions on the DBpedia youtube channel.

KnowConn Conference 2020

Our CEO, Sebastian Hellmann, gave the talk ‘DBpedia Databus – A platform to evolve knowledge and AI from versioned web files’ on December 2, 2020 at the KnowledgeConnexions Online Conference. It was a great success and we received a lot of positive and constructive feedback for the DBpedia Databus.

DBpedia Archivo

On December 7, 2020 we introduced the DBpedia Archivo – an augmented ontology archive and interface to implement FAIRer ontologies. Each ontology is rated with 4 stars measuring basic FAIR features. We would like to call on all ontology maintainers and consumers to help us increase the average star rating of the web of ontologies by fixing and improving its ontologies. You can easily check an ontology at https://archivo.dbpedia.org/info. Further infos on how to help us are available in a detailed post on our blog. 

Member features on the blog

At the beginning of November 2020 we started the member feature on the blog. We gave DBpedia members the chance to present special products, tools and applications. We published several posts in which DBpedia members, like Ontotext, GNOSS, the Semantic Web Company, TerminusDB or FinScience shared unique insights with the community. In the beginning of 2021 we will continue with interesting posts and presentations. Stay tuned!

We do hope we will meet you and some new faces during our events next year. The DBpedia Association wants to get to know you because DBpedia is a community effort and would not continue to develop, improve and grow without you. We plan to have meetings in 2021 at the Knowledge Graph Conference, the LDK conference in Zaragoza, Spain and the SEMANTiCS conference in Amsterdam, Netherlands.

Happy New Year to all of you! Stay safe and check Twitter, LinkedIn and our Website or subscribe to our Newsletter for the latest news and information.

Home Sweet Home – The 13th DBpedia Community Meeting

For the second time now, we co-located one of our DBpedia community meetings with the LDK-conference. After the previous edition in Galway two years ago, It was Leipzig’s turn to host the event. Thus, the 13th DBpedia community meeting took place in this beautiful city which is also home to the DBpedia Association’s head office. Win, Win we’d say. 

After a very successful LDK conference May 20th-21st, representatives of the European DBpedia community met at Villa Ida Mediencampus,  on Thursday, May 23rd, to present their work with DBpedia and to exchange about the DBpedia Databus.  

For those of you who missed it or for those who want a little retrospective on the day, this blog post provides you with a short LDK-wrap-up as well as a recap of our DBpedia Day.

First things first

First and foremost, we would like to thank LDK organizers for co-locating our meeting and thus enabling fruitful synergies, and a platform for the DBpedia community to exchange.

LDK

The first presentation that kicked-off the conference was given by Prof. Christiane Fellbaum from Princeton University. The topic of her talk was on “Mapping the Lexicons of Signs and Words” with the main focus on her research of mapping WordNet and SignStudy, a resource for American Sign Language. Shortly after, Prof Eduard Werner from Leipzig University gave a very exciting talk on the “Sorbian languages”. He discussed the nature of the Sorbian languages, their historical background, and the unfortunate imminent extinction of lower Sorbian due to a decline of native speakers.

The first day of LDK was full of exciting presentations related to various language-oriented topics. Researchers exchanged about linguistic vocabularies, SPARQL query recommendations, role and reference grammar, language detection, entity recognition, machine translation, under-resourced languages, metaphor identification, event detection and linked data in general. The first day ended with fruitful discussions during the poster session. After at the end of the first conference day, LDK visitors had the chance to mingle with locals in some of Leipzig’s most exciting bars during a pub crawl.

Prof. Christian Bizer from the University of Mannheim opened the second day with a keynote on “Schema.org Annotations and Web Tables: Underexploited Semantic Nuggets on the Web?”. In his talk, he gave a nice overview of the research on knowledge extraction around the large-scale Web Data Commons corpus, findings, open challenges and possible exploitations of this corpus.

The second day was busy with four sessions, each populated with presentations on exciting topics ranging from relation classification, dictionary linking and entity linking, to terminology models, topical thesauri and morphology.

The series of presentations was ended with an Organ Prelude played by David Timm, the University Music Director at the Leipzig University. Finally, the day and the conference was concluded with a conference dinner at Moritzbastei, one of Leipzig’s famous cultural centres.

DBpedia Day

On May 23rd, the DBpedia Community met for the 13th DBpedia community meeting. The event attracted more than 60 participants who extended their LDK experience or followed our call to Leipzig.

Opening & keynotes

The meeting was opened by Dr. Sebastian Hellmann, the executive director of the DBpedia Association. He gave an overview of the latest developments and achievements around DBpedia, with the main focus on the DBpedia Databus technologies. The first keynote was given by Dr. Peter Haase, from metaphacts, with an unusual interactive presentation on “Linked Data Fun with DBpedia”. The second keynote speaker was Prof. Heiko Paulheim, presenting findings, challenges and results from his work on the construction of the DBkWiki Knowledge Graph by exploiting the DBpedia extraction framework.

Showcase session

The showcases session started with a presentation given by  Krzysztof Węcel on “Citations and references in DBpedia”, followed by Peter Nancke with a presentation on the “TeBaQA Question Answering System”, Maribel Acosta Deibe speaking about “Crowdsourcing the Quality of DBpedia” and finally, a presentation by Angus Addlesee on “Data Reconciliation using DBpedia”.

NLP & DBpedia session

The DBpedia & NLP session was opened by  Diego Moussallem presenting the results from his work on “Generating Natural Language from RDF Data”. The second presentation was given by Christian Jilek on the topic of “Named Entity Recognition for Real-Time Applications”, which at the same time won the best research paper at the LDK conference. Next, Jonathan Kobbe presented the best student paper at the LDK conference on the topic of “Argumentative Relation Classification”. Finally, Edgard Marx closed the session with an overview presentation on “From the word to the resource”.

 

Side-Event – Hackathon

The “Artificial Intelligence for Smart Agriculture” Hackathon focused on enhancing the usability of automatic analysis tools which utilize semantic big data for agriculture, as well as conducting an outreach of the DataBio project for the DBpedia community. The event was supported by PNO, Spacebel, PSNC, and InfAI e.V.

We improved the visualization module of Albatross, a platform for processing and analyzing Linked Open Data, and added functionalities to geo-L, the geospatial link discovery tool.  

In addition, we presented a paper about Linked Data publication pipelines, focusing on agri-related data, at the co-located LSWT conference.

Wrap Up

After the event, DBpedians joined the DBpedia Association in the nearby pub Gosenschenke to delve into more vital talks about the Semantic Web world, Linked Data & DBpedia.

In case you missed the event, all slides and presentations are available on our website. Further insights feedback and photos about the event can be found on Twitter via #DBpediaLeipzig.

We are currently looking forward to the next DBpedia Community Meeting, on Sept, 12th in Karlsruhe, Germany. This meeting is co-located with the SEMANTiCS Conference. Contributions are still welcome. Just ping us via dbpedia@infai.org and show us what you’ve got. You should also get in touch with us if you want to host a DBpedia Meetup yourself. We will help you with the program, the dissemination or organizational matters of the event if need be.

Artificial Intelligence (AI) and DBpedia

Artificial Intelligence (AI) is currently the central subject of the just announced ‘Year of Science’  by the Federal German Ministry. In recent years, new approaches were explored on how to facilitate AI, new mindsets were established and new tools were developed, new technologies implemented. AI is THE key technology of the 21st century. Together with Machine Learning (ML), it transforms society faster than ever before and, will lead humankind to its digital future.

In this digital transformation era, success will be based on using analytics to discover the insights locked in the massive volume of data being generated today. Success with AI and ML depends on having the right infrastructure to process the data.[1]

The Value of Data Governance

One key element to facilitate ML and AI for the digital future of Europe, are ‘decentralized semantic data flows’, as stated by Sören Auer, a founding member of DBpedia and current director at TIB, during a meeting about the digital future in Germany at the Bundestag. He further commented that major AI breakthroughs were indeed facilitated by easily accessible datasets, whereas the Algorithms used were comparatively old.

In conclusion, Auer reasons that the actual value lies in data governance. Infact, in order to guarantee progress in  AI, the development of a common and transparent understanding of data is necessary. [2]

DBpedia Databus – Digital Factory Platform

The DBpedia Databus  – our digital factory Platform –  is one of many drivers that will help to build the much-needed data infrastructure for ML and AI to prosper.  With the DBpedia Databus, we create a hub that facilitates a ‘networked data-economy’ revolving around the publication of data. Upholding the motto, Unified and Global Access to Knowledge, the databus facilitates exchanging, curating and accessing data between multiple stakeholders  – always, anywhere. Publishing data on the Databus means connecting and comparing (your) data to the network. Check our current DBpedia releases via http://downloads.dbpedia.org/repo/dev/.

DBpediaDay – & AI for Smart Agriculture

Furthermore, you can learn about the DBpedia Databus during our 13th DBpedia Community meeting, co-located with LDK conference,  in Leipzig, May 2019. Additionally, as a special treat for you, we also offer an AI side-event on May 23rd, 2019.

May we present you the thinktank and hackathon  – “Artificial Intelligence for Smart Agriculture”. The goal of this event is to develop new ideas and small tools which can demonstrate the use of AI in the agricultural domain or the use of AI for a sustainable bio-economy. In that regard, a special focus will be on the use and the impact of linked data for AI components. 

In short, the two-part event, co-located with LSWT & DBpediaDay, comprises workshops, on-site team hacking as well as presentations of results. The activity is supported by the projects DataBio and Bridge2Era as well as CIAOTECH/PNO. All participating teams are invited to join and present their projects. Further Information are available here. Please submit your ideas and projects here.  

 

Finally, the DBpedia Association is looking forward to meeting you in Leipzig, home of our head office. Pay us a visit!
