Only 8 days left to reserve your seat for our 3rd US DBpedia Community Meeting. We are happy to announce that the 11th DBpedia Meeting will be held in Cupertino, California on October 12th 2017, hosted by Apple Inc.
The meetup focuses on connecting the community interested in DBpedia and Knowledge Graphs in general, has included lightning talks by distinguished speakers (e.g. from Stanford, Google, IBM Watson, Netflix, LinkedIn, Wikimedia Foundation, Nuance, etc.). Talk topics have extended also to natural language processing, knowledge representation, information extraction, integration and retrieval, graph databases, knowledge base embeddings and machine learning.
We are looking forward to meeting again in person with the US-based DBpedia Community.
After the success of the last two community meetings in Sunnyvale and in Galway, we thought it is time to go Orange again. During the SEMANTiCS 2017 in Amsterdam, Sep 11-14, the DBpedia Community met on the 14th of September. First and foremost, we would like to thank the Institute for Applied Informatics for supporting our community and many thanks to the Meervaart Theatre and the SEMANTiCS for hosting our community meeting.
During the opening session, Chris Welty, Google Researcher, presented Even the Changes Are Changing: A New Age of Cognitive Computing. He introduced the impact and challenges of question answering & AI as well as the development of Jeopardy through technical changes. Victor de Boer from the VU University talked about Semantic Technology for Development: Semantic Web without the Web?. He demonstrated the use of semantic technology in the challenging technical environment of developing countries. Both talks illustrated the ever growing importance of semantic technology and AI each placed at opposite sites of the technology spectrum, from Raspberry PIs to High Performance Clusters.
The DBpedia Showcase Session started with an interactive interview. Sebastian Hellmann (AKSW/KILT) talked with Jan-Bart de Vreede (Kennisnet, former member of the Wikimedia Foundation) about the challenges of growing an open community and creating a more formal structure. They discussed advantages, pitfalls and what lessons can be learned from other communities such as Wikimedia. Afterwards Markus Freudenberg (AKSW/KILT) introduced the highlights of the 2016-10 DBpedia Release.
At this session, five speakers presented how to utilize DBpedia in novel and interesting ways. Including:
Virtuoso 8 and Scalable Attributed-based Access Controls (ABAC) by Patrick van Kleef (Openlink Software)
Learning to Associate DBpedia Entities like Humans by Joern Hees (DFKI) (demo)
Towards Using UnifiedViews for Executing DBpedia Data Extraction and Curation Tasks by Tomas Knap (Semantic Web Company)
Sustainable Linked Data Generation: The Case of DBpedia by Wouter Maroy (imec)
As a regular part of the DBpedia Community Meeting, we had two parallel sessions in the afternoon where DBpedia newbies can learn about what DBpedia is and how to use the DBpedia datasets. Participants who wanted to learn DBpedia basics joined the tutorial session by Markus Freudenberg (DBpedia Release Manager). The DBpedia Association Hour provided a platform for the community to discuss the results of the DBpedia Strategy Survey 2017. This survey was prepared by Sören Auer and the DBpedia Board members to get to know what the DBpedia Community thinks about DBpedia’s strategic priorities and how the funds of the DBpedia Association should be spent. Even if 45 minutes were not adequate to review all survey questions, this session proved to be beneficial due to a really agile and dynamic discussion. A better cooperation and communication between the Association and the different national and language chapter is only one suitable key which was embraced by the community to facilitate problem solving and DBpedia’s organization.
The sessions in the afternoon highlighted two important fields of research and development, namely DBpedia Ontology and DBpedia & NLP. At the DBpedia Ontology Session, Gustavo Publio (AKSW/KILT) presented data quality issues in DBpedia and highlighted the challenges on redesign the DBpedia Ontology (slides). Wouter Maroy (imec) and Ismael Rodríguez (Polytechnic University of Catalonia) showcased the DBpedia Mappings Front-End Administration, which they created during this year’s Google Summer of Code project. If you are interested in career opportunities at DBpedia, check out Wouter’s success story here.
At the same time, Milan Dojchinovski (AKSW/KILT) chaired the DBpedia & NLP session with five very interesting talks. In the following you will find all presentations given during this session:
DBpedia Spotlight 1.0 – A new Release by Sandro Coelho (DBpedia Association) slides
TextExt winner – Lector: RDF Triples Extraction from Wikipedia Text by Matteo Cannaviccio, Roma Tre University slides
Chaudron: Extending DBpedia with Measures by Julien Subercaze, Télécom Saint-Etienne & Université Jean Monnet slides
Dutch DBpedia Hour & Joint Workshop
Enno Meijers (National Library of the Netherlands) chaired the Dutch DBpedia Hour. In this open session members of the Dutch DBpedia Language Chapter discussed tasks and responsibilities for sustaining and developing the Dutch DBpedia as well as communication, technical infrastructure and content improvement of the DBpedia Dutch Language Chapter. The reference for this discussion was the tasks and responsibilities stated in the Memorandum of Understanding signed by Huygens ING, Koninklijke Bibliotheek, Vrije Universiteit Amsterdam, iMec and Beeld en Geluid. Outcome of this session was an agreement on the approach for creating an operational plan.
Simultaneously, DBpedia joint a session with the Workshop “Linked Data Quality Assessment and Improvement from Academia to Industry”. The presentations are available below:
In the closing session, Sebastian Hellmann (AKSW/KILT) announced a new collaboration to strengthen the DBpedia NLP Department. Via videostream we talked with Mike Tung and Filipe Mesquita from diffbot, about NLP and the relation extraction from Wikipedia articles. If you are interested in the new collaboration, please check diffbot’s slides here.
All slides and presentations are also available on our Website and you will find more feedback and photos about the event on Twitter via #DBpediaAmsterdam17.

We are now looking forward to the 11th DBpedia Community Meeting which will be held on 12th of October 2017 in Cupertino, California. Visit our event page for further updates.
We are very pleased to announce that all of this year’s Google Summer of Code students made it successful through the program and passed their projects. All codes have been submitted, merged and are ready to be examined by the rest of the world.
Marco Fossati, Dimitris Kontokostas, Tommaso Soru, Domenico Potena, Emanuele Storti , anastasia Dimiou, Wouter Maroy, Peng Xu, Sandro Coelho and Ricardo Usbeck, members of the DBpedia Community, did a great job in mentoring 7 students from around the world.All of the students enjoyed the experiences made during the program and will hopefully continue to contribute to DBpedia in the future.
“GSoC is the perfect opportunity to learn from experts, get to know new communities, design principles and work flows.” (Ram G Athreya)”
Now, we would like to take that opportunity to give you a little recap of the projects mentored by DBpedia members during the past months. Just click below for more details .
The goal of the project was to create a front-end application that provides a user-friendly interface so the DBPedia community can easily view, create and administrate DBpedia mapping rules using RML. The developed system includes user administration features, help posts, Github mappings synchronization, and rich RML related features such as syntax highlighting, RML code generation from templates, RML validation, extraction and statistics. Part of these features are possible thanks to the interaction with the DBPedia Extraction Framework. In the end, all the functionalities and goals that were required have been developed, with many functional tests and the approval of the DBpedia community. The system is ready for production deployment. For further information, please visit the project blog. Mentors: Anastasia Dimou and Wouter Maroy (Ghent University), Dimitris Kontokostas (GeoPhy HQ).
DBpedia Chatbot is a conversational chatbot for DBpedia which is accessible through the following platforms: a Web Interface, Slack and Facebook Messenger.
The bot is capable of responding to users in the form of simple short text messages or through more elaborate interactive messages. Users can communicate or respond to the bot through text and also through interactions (such as clicking on buttons/links). The bot tries to answer text based questions of the following types: natural language questions, location information, service checks, language chapters, templates and banter. For more information, please follow the link to the project site.Mentor: Ricardo Usbeck (AKSW).
Knowledge base embeddings has been an active area of research. In recent years a lot of research work such as TransE, TransR, RESCAL, SSP, etc. has been done to get knowledge base embeddings. However none of these approaches have used DBpedia to validate their approach. In this project, I want to achieve the following tasks: i) Run the existing techniques for KB embeddings for standard datasets. ii) Create an equivalent standard dataset from DBpedia for evaluations. iii) Evaluate across domains. iv) Compare and Analyse the performance and consistency of various approaches for DBpedia dataset along with other standard datasets. v) Report any challenges that may come across implementing the approaches for DBpedia. For more information, please follow the links to her project blog and GitHub-repository.Mentors: Tommaso Soru (AKSW) and Sandro Coelho (KILT).
The project defined embeddings to represent classes, instances and properties by implementing Random Vector Accumulators with additional features in order to better encode the semantic information held by the Wikipedia corpus and DBpedia graphs. To test the quality of embeddings generated by the RVA, lexical memory vectors of locations were generated and tested on a modified subset of the Google Analogies Test Set. Check out further information via Akshay’s GitHub-repo. Mentors: Tommaso Soru (AKSW) and Xu Peng (University of Alberta).
Wikipedia is full of data hidden in tables. The aim of this project was to explore the possibilities of exploiting all the data represented with the appearance of tables in Wiki pages, in order to populate the different chapters of DBpedia through new data of interest. The Table Extractor has to be the engine of this data “revolution”: it would achieve the final purpose of extracting the semi structured data from all those tables now scattered in most of the Wiki pages. In this page you can observe dataset (english and italian) extracted using table extractor . Furthermore you can read log file created in order to see all operations made up for creating RDF triples. I recommend to also see this page, that contains the idea behind the project and an example of result extracted from log files and .ttl dataset. For more details see Luca’s Git-Hub repository.Mentors: Domenico Potena and Emanuele Storti (Università Politecnica delle Marche).
Wikipedia represents a comprehensive cross-domain source of knowledge with millions of contributors. The DBpedia project tries to extract structured information from Wikipedia and transform it into RDF.
The main classification system of DBpedia depends on human curation, which causes it to lack coverage, resulting in a large amount of untyped resources. DBTax provides an unsupervised approach that automatically learns a taxonomy from the Wikipedia category system and extensively assigns types to DBpedia entities, through the combination of several NLP and interdisciplinary techniques. It provides a robust backbone for DBpedia knowledge and has the benefit of being easy to understand for end users. details about his work and his code can e found on the projects site. Mentors: Marco Fossati (Università degli Studi di Trento) and Dimitris Kontokostas (GeoPhy HQ).
This project aimed to augment upon the already existing list-extractor project by Federica in GSoC 2016. The project focused on the extraction of relevant but hidden data which lies inside lists in Wikipedia pages. Wikipedia, being the world’s largest encyclopedia, has humongous amount of information present in form of text. While key facts and figures are encapsulated in the resource’s infobox, and some detailed statistics are present in the form of tables, but there’s also a lot of data present in form of lists which are quite unstructured and hence its difficult to form into a semantic relationship. The main objective of the project was to create a tool that can extract information from Wikipedia lists and form appropriate RDF triplets that can be inserted in the DBpedia dataset. Fore details on the code and about the project check Krishanu’s blog and GitHub-repository.Mentors: Marco Fossati (Università degli Studi di Trento), Domenico Potena and Emanuele Storti (Università Politecnica delle Marche).
We are regularly growing our community through GSoC and can deliver more and more opportunities to you. Ideas and applications for the next edition of GSoC are very much welcome. Just contact us via email or check our website for details.
Again, DBpedia is planning to be a vital part of the GSoC Mentor Summit, from October 13th -15th, at the Google Campus in Sunnyvale California. This summit is a way to say thank you to the mentors for the great job they did during the program. Moreover it is a platform to discuss what can be done to improve GSoC and how to keep students involved in their communities post-GSoC.
And there is more good news to tell. DBpedia wants to meet up with the US community during the 11th DBpedia Community Meeting in California. We are currently working on the program and keep you posted as soon as registration is open.
We are happy to announce that the 10th DBpedia Community Meeting will be held in Amsterdam, Netherlands. During the SEMANTiCS 2017, Sep 11-14, the DBpedia Community will get together on the 14th of September for the DBpedia Day.

After our 2nd Community Meeting in the US, we delighted the Irish DBpedia Community with the 9th DBpedia Community Meeting, which was co-located with the Language, Data and Knowledge Conference 2017 in Galway at the premises of the NUI Galway.
First and foremost, we would like to thank John McCrae (Insight Centre for Data Analytics, NUI Galway) and the LDK Conference for co-hosting and support the event.
The focus of this Community Meeting was the Irish DBpedia and Linked Data Community in Ireland. Therefore we invited local data scientists as well as European DBpedia enthusiasts to discuss the state of Irish Linked Data.
The meeting started with two compelling keynotes by Brian Ó Raghallaigh, Dublin City University and Logainm.ie, and Sharon Flynn, NUI Galway and Wikimedia Ireland. Brian presented Logainm.ie, a data use case about placenames in Ireland with a special focus on linked Logainm and machine-readable data.
His insightful presentation was followed by Sharon Flynn talking about Wikimedia in Ireland and the challenges of “this monumental undertaking” with particular reference to the Wikimedia Community in Ireland.
For more details on the content of the presentations, follow the links to the slides.
As a regular part of the DBpedia Community Meeting we have two parallel sessions in the afternoon where DBpedia newbies can learn about what DBpedia is and how to use the DBpedia data sets.
Participants who wanted to learn DBpedia basics joined the DBpedia Tutorial Session byMarkus Freudenberg (DBpedia Release Manager). The DBpedia Association Hour provided a platform for the community to discuss and give feedback.
Additionally, Sebastian Hellmann and Julia Holze, members of the DBpedia Association, updated the participants about the growing number of the DBpedia Association members, the formalized DBpedia language chapters, the established DBpedia Community Committee and they informed about technical developments such as the DBpedia API.
Ontology Engineering and Software Alignment in the ALIGNED Project
The afternoon session started with the DBpedia 2016-10 release update by Markus Freudenberg (DBpedia Release Manager). Following this, Kevin Chekov Feeney, (Trinity College Dublin) presented the software alignment in the ALIGNED project. He talked about “Generating correct-by-construction semantic datasets from unstructured, semi-structured and badly structured data sources”.
At this point, we also like to thank the ALIGNED project for the development ofDBpedia as a project use case and for covering parts of the travel cost.
Session about Irish Linked Data Projects
Chaired by Rob Brennan and Bianca Pereira, the speakers in the last session presented new Irish Linked Data Projects, for example GeoHive, BIOOPENER and the TCD Open Linked Data Engagement Fund Project. The following panel session gave DBpedia and Linked Data enthusiasts a platform for exchange and discussion. Outcome of this session was the creation of a roadmap for the Irish Linked Data with all participants.
Following, you find a list of all presentations of this session:
Closing this session John McCrae announced that the next edition of the Language, Data and Knowledge (LDK) Conference is scheduled for 2019 in Germany. We at the DBpedia Association are now looking forward to welcome the LDK Community in Leipzig!
Social Evening Event
The Community Meeting slowly came to an end with our social evening event, which was held at the PorterShed in Galway. The evening session revolved around the topic How to exploit data commercially? and featured two short impulse talks. Paul Buitelaar started the session by presenting “Kibi”, which is an Open Source platform for Data Intelligence based on the search engine Elasticsearch. Finally, Sebastian Hellmann talked about “Improving the Utility of DBpedia by co-designing a public and commercial DBpedia API” (slides).
Summing up, the 9th DBpedia Community Meeting brought together more than 45 DBpedia enthusiasts from Ireland and Europe who engaged in vital discussions about Linked Data, DBpedia use cases and services.
Special thanks go to LDK 2017 for hosting the meeting.

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.
