After our successful meeting in Poznan in 2015, we thought it is time to meet the Polish DBpedia community again. The DBpedia meetup will be held on 22th of November 2016 at the Poznań University of Economics and Business. This meetup aims at the presentation of semantic web technologies and their use in applications by entrepreneurs.
After the largest DBpedia meeting to date we decided it was time to cross the Atlantic for the second time for another meetup. Two weeks ago the 8th DBpedia Community Meeting was held in Sunnyvale, California on October 27th 2016.
Pablo Mendes from Lattice Data Inc. opened the main event with a short introduction setting the tone for the evening. After that Dimitris Kontokostas gave technical and organizational DBpedia updates. The main event attracted attendees with lightning talks from major companies actively using DBpedia or interested in knowledge graphs in general.
Four major institutions described their efforts to organize reusable information in a centralized knowledge representation. Google’s Tatiana Libman presented (on behalf of Denny Vrandečić) the impressive scale of the Google Knowledge graph, with 1B+ entities and over 100 billion facts.
Yahoo’s Nicolas Torzec presented the Yahoo knowledge graph, with focus on their research on extracting data from Web tables to expand their knowledge which includes DBpedia as an important part. Qi He from LinkedIn focused mostly on how to model a knowledge graph of people and skills, which becomes particularly interesting with the possibility of integration with Microsoft’s Satori Graph. Such an integration would allow general domain knowledge and very specific knowledge about professionals complementing one another. Stas Malyshev from Wikidata presented statistics on their growth, points of contact with DBpedia as well as an impressive SPARQL query interface that can be used to query the structured data that they are generating.
Three other speakers focused on the impact of DBpedia in machine learning and natural language processing. Daniel Gruhl from IBM Watson gave the talk “Truth for the impatient” where he showed that a knowledge model built from DBpedia can help costs and time to value for extracting entity mentions with higher accuracy. Pablo Mendes from Lattice Data Inc. presented their approach that leverages DBpedia and other structured information sources for weak supervision to obtain very strong NLP extractors. Sujan Perera from IBM Watson discussed the problem of identifying implicit mentions of entities in tweets and how the knowledge represented in DBpedia can be used to help uncover those references.
Another three speakers focused on applications of DBpedia and knowledge graphs. Margaret Warren from Metadata Authoring Systems, LLC presented ImageSnippets and how background knowledge from DBpedia allows better multimedia search through inference. For instance, by searching for “birds” you may find pictures that haven’t been explicitly tagged as birds but for which the fact can be inferred from DBpedia. Jans Aasman from Franz Inc presented their company’s approach to Data Exploration with Visual SPARQL Queries. They described opportunities for graph analytics in the medical domain, and discussed how DBpedia has been useful in their applications. Finally, Wang-Chiew Tan presented their research at RIT relating to building chatbots, among other projects that relate to using background knowledge stored in computers to enrich real life experiences.
Overall the talks were very high quality and fostered plenty of discussions afterwards. We finalized the event with a round of introductions where every attendee got to say their name and affiliation to help them connect with one another throughout the final hour of the event.
All slides and presentations are also available on ourWebsite and you will find more feedback and photos about the event on Twitter via #DBpediaCA.
Less than 24 hours left to reserve your seat for our 2nd US DBpedia Community meeting. The meeting will be held in Sunnyvale on October 27th 2016, hosted by Yahoo. Over 85 participants registered so far, we will offer 20 more tickets. So come and get your ticket to be part of this event.
The event will feature talks from Yahoo, IBM Watson, LinkedIn, Lattice, Wikimedia, Frank Inc, Knoesis, RIT and ImageSnippets. The topics will include knowledge graphs & machine learning, open data, open source and startups. Please read below on different ways you can participate. We are looking forward to meeting again in person with the US-based DBpedia community.
We thought it was about time to go orange again, meet the Dutch DBpedia Chapter and to meet and celebrate the growing dutch DBpedia community. Thus, following our successful US-event past November, the National Library of the Netherlands hosted the 6th DBpedia community meeting in The Hague on February 12th.
First and foremost, we would like to thank TNO for organizing the pre-event and the National Library of the Netherlands, especially Menno Rasch (Director of KB operations), for sponsoring the catering during the DBpedia community meeting.
Before diving into DBpedia topics, we had a welcome reception on February 11th with snacks and drinks at TNO – New Babylon. Around 40 people from the DBpedia community, members from TNO and its Data Science Department and representatives from the Platform Linked Data Netherlands engaged in vital exchanges about Linked Data topics in the Netherlands.
Sebastian Hellmann gave a short introduction about DBpedia and the recently found DBpedia Association. After Jean-Louis Roso talked about the TNO Data Science Department and current developments and projects, Erwin Folmerpresented the platform Linked Data Netherlands (PiLOD).
A poster and demo session right after gave people from TNO the opportunity to present and discuss projects currently carried out at TNO.
Following, you find a short list of poster-presentation during the pre-event:
The Smart Appliances REFerence ontology (SAREF)Standardization in IoT
The following social gathering with snacks and drinks, encouraged talks about current developments in the DBpedia community and about ongoing projects. According to TNO representative Laura Daniel, the pre-event was very successful. She summarized the evening of the welcome reception: “It was very inspiring to see the DBpedia community in action. There were lots of interesting projects that use DBpedia as well as lively discussions on the challenges faced by the community, and of course, the event was a great opportunity for networking!”
Following the pre-event, the main event attracted 95 participants and featured special session dedicated to the DBpedia showcases, the DBpedia ontology and challenges of DBpedia and Digital Heritage.
During the opening session, Menno Rasch, host of the meeting and Director of KB operations, highlighted the importance to raise awareness of the DBpedia brand in order to build a DBpedia community.
The newly found DBpedia Association and the related new charter regulating organizational issues in the DBpedia community was one of the focuses during the early morning hours, right before several interesting keynote presentations opened the discussion about DBpedia and its usage in the Netherlands.
Marco de Niet, representative of Digital Heritage Foundation (DEN Foundation), the Dutch knowledge centre for digital heritage,talked about “the National Strategy for Digital Heritage in the Netherlands”.
Marco BrattingaandArjen Santemafrom the Land Registry and Mapping Agency (Kadaster)presented a framework to describe the data and metadata in registration in relation to a concept schema that describes what the registration is about. Apart from the ideas behind the framework, their presentation included a showcase of examples from the cadastral registration as well as the topographic map and the information node addresses and buildings.
The morning session was closes byPaul Groth, fromElsevier giving a presentation about knowledge graph construction and the Role of DBPedia and other Wikipedia based knowledge. He discussed the importance of structured data as key to coordinate data in order to build better taxonomies. He also pointed towards the importance of having an updated publicly available knowledge graph as a reference for constructing internal knowledge graphs.
After Lunch Track
DBpedia is one of the biggest and most important focal point of the Linked Open Data movement. Thus, the after-lunch-track focused very much on DBpedia Usages during the dedicated showcase session, which started with the new DBpedia & DBpedia+ Data Stack release (planned for 2016-04).
Afterwards, the session continued with further DBpedia related discussions, in which various practical DBpedia matters such as DBpedia in the EUROPEANA Food and Drink project, the use of DBpedia for improved vaccine information systems or using Elasticsearch + DBpedia to maintain a searchable database of global power plants were tackled.
The afternoon track came along with four DBpedia highlight-sessions, namely DBpedia and Ontologies, DBpedia and Heritage, DBpedia hands-on development and DBpedia and NLP. Firstly, the DBpedia ontology group discussed possible ontology usages and presented the results of the latest DBpedia Ontology survey. In the following 75 minutes during the DBpedia and Heritage session, special challenges and opportunities of reference data for digital heritage were addressed by experts from EUROPEANA, iMinds, RCE and KB, the National Library of the Netherlands. Thirdly, members of the DBpedia Association and the AKSW/KILT group from Leipzig led a practical session for developers and DBpedia enthusiasts to talk about technical issues and challenges in DBpedia as well as they held a Tutorial session for DBpedia Newbies.
The end of the event was dedicated to NLP and the application of Linked Data on Language Technologies, especially entity linking, topics which are of vital importance for the research of AKSW/KILT members at the University of Leipzig.
Following, you find a list of all presentations given during the meeting.
All slides and presentations are also available on our Website and you will find more feedback and photos about the event on Twitter via #DBpediaDenHaag.
Summing up, the 6th community meeting brought together more than 95 DBpedia enthusiast from the Netherlands and Europe which engaged in vital conversations about interesting projects and approaches to questions/problems revolving around DBpedia, not only during the dedicated session but also during networking breaks. The recently found DBpedia Association was strongly represented with presentations from Sebastian Hellmann, Dimitris Kontokostas, Nilesh Chakraborty, as well as Markus Freudenberg.
Finally, we would like to thank the organizers Enno Meijers, Richard Nagelmaker, Gerald Wildenbeest, Gerard Kuys, Monika Solanki and representatives of the DBpedia Association such as Dimitris Kontokostas and Sebastian Hellmann for devoting their time to the organization of the meeting and the programme. We are now looking forward to the 7th DBpedia Community Meeting, which will be held in the city of Leipzig again, during the Semantics conference in September 15th, 2016.
