On 16 April, as part of Data Week Leipzig, the DBpedia training on the topic of “Harnessing the Power of DBpedia: Transforming Data into Knowledge” took place with three sessions and different presentations in each. This workshop was designed to introduce you to the vast capabilities of DBpedia and its suite of technologies that are reshaping the way we interact with the world’s knowledge. This tutorial gave all participants an insight into the comprehensive DBpedia technology ecosystem. It was also an opportunity to learn how to integrate and leverage these components to create innovative solutions.

Opening of the DBpedia Training

Milan Dojchinovski (InfAI, DBpedia Association, CTU Prague) and Sebastian Hellmann (InfAI, DBpedia Association) started the opening of the DBpedia Training with general information on the tutorial. Topics of this training were DBpedia in the nutshell, the DBpedia Databus, Databus Use Cases and Deploying your own DBpedia. We also presented four showcases: Semantic Indexing and Search using DBpedia tech, CI and Databus publishing using Jenkins, Databus Metadata Overlay Search System and Terminology Server using Databus, Lookup and Archivo.

Session 1: DBpedia Tech Overview and DBpedia Databus

In the first session, Milan Dojchinovski gave an overview of DBpedia and Sebastian Hellmann gave an introduction to Databus Use Cases, followed by the presentations on “Databus and Collections” and “Making your own DBpedia KG” by Jan Forberg.

Session 2: DBpedia and Databus Showcases: Semantic Indexing and CI

The second session started with “Semantic Indexing and Search using DBpedia Spotlight and Databus” by Jan Forberg which was followed by Kirill Yankov with “CI and Databus publishing using Jenkins”.

Session 3: DBpedia and Databus Showcases (cont.): Metadata Overlay Search and Terminology Server

In the last session, Jan Forberg and Jonathan Justavino Lüderitz talked about “Databus Metadata Overlay Search System (MOSS)”. The final presentation was given by Johannes Frey on “Terminology Server using Databus, Lookup and Archivo”.

Closing Session

Finally, in the closing session, chaired by Milan Dojchinovski (InfAI, DBpedia Association, CTU Prague) there was time for a little wrap-up,  questions and feedback on the DBpedia Training.

The slides from the DBpedia Training are available here.

We are looking forward to more DBpedia events in the next months. Stay safe and check Twitter or LinkedIn. Furthermore, you can subscribe to our Newsletter for the latest news and information around DBpedia.

The post DBpedia – GSoC Bonding Period 2024 appeared first on DBpedia Association.

We have been accepted to be part of this incredible program to support young ambitious developers who want to work with open-source organizations like DBpedia. So far, each year has brought us new project ideas, many amazing students and great project results that shaped the future of DBpedia. Even though Covid-19 changed a lot in the world, it couldn’t shake Google Summer of Code (GSoC) much. The program, designed to mentor youngsters from afar is almost too perfect for us. One of the advantages of GSoC is, especially in times like these, the chance to work on projects remotely, but still obtain a first deep dive into Open Source projects like us.

DBpedia is now looking for contributors who want to work with us during the upcoming summer months.  

What is Google Summer of Code?

Google Summer of Code is a global program focused on bringing developers into open source software development. Funds will be given to all new beginner contributors to open source over 18 years to work for two and a half months (or longer) on a specific task. For GSoC-Newbies, this short video and the information provided on their website will explain all there is to know about GSoC2024.

And this is how it works …

Application Procedure GSoC2024

Further information on the application procedure is available in our DBpedia Guidelines. There you will find information on how to contact us and how to appropriately apply for GSoC2024. Please also note the official GSoC 2024 timeline for your proposal submission and make sure to submit on time. Unfortunately, extensions cannot be granted. Final submission deadline is April 2, 2024 at 18:00 UTC.

Tutorial @  Language, Data and Knowledge conference

On 13th of September, 2023, an exciting tutorial took place at the University of Vienna in the Center for Translation Studies as part of the LDK 2023. The LDK conference focuses on the acquisition, maintenance and use of language data in the context of data science and knowledge-based applications. The tutorial was opened by Milan Dojchinovski (InfAI, DBpedia Association, CTU in Prague). This was followed by three sessions, which were accompanied by many real-world practical use cases, on the DBpedia Knowledge Graph, the infrastructure and the use of the databus data publishing platform. Check more details on our events page. 

DBpedia Day @ SEMANTiCS in Leipzig 

DBpedia Day was once again part of the program at this year’s SEMANTICS conference 2023. It was held on 20th of September at the HYPERION Hotel Leipzig with up to 100 DBpedians. Once again this year, our CEO Sebastian Hellmann opened the day with a presentation of the “DBpedia Databus version 2.1.0”. This was followed by the exciting keynote speech “Towards Foundation Models for Data Spaces” by Edward Curry from the University of Galway, Ireland. Afterwards, we organized the member session and the DBpedia Science Talk session. All slides can also be found on our  events page.

Databus

Databus pre-launch announcement

We are in the final stage of the DBpedia Databus open software release (GitHub). Remaining issues include quality of life and UI improvements. Check out the Databus feature matrix for our lightweight, scalable, adaptable, powerful Data Catalog Platform (direct download link, persistent data identifier on the databus). Contact dbpedia@infai.org for demo, business, or research proposal inquiries.

Databus excels at cataloging de-central data of any filetype using RDF/DCAT. We selected a few initial focal use cases, where the Databus serves as:

1. AIModelHub for AI training data, models, validation, and deployment.
2. Research Data Management Catalog for research institutes and communities.
3. Supply-Chain-Management Platform for product information collection along the supply chain and construction of Digital Product Passports.
4. Community Data Portal, e.g., for the DBpedia Community.

DBpedia Contributions will be enabled soon, taking DBpedia to the moon! 🚀

In DBpedia’s future, the Databus will be used to collect community contributions more effectively, giving DBpedia an enormous boost in quantity and quality. https://databus.dbpedia.org already catalogs over 350k files with over 1 Million file downloads per month!  We are preparing showcases, templates, and documentation for these community contribution types:

1. Community Extensions such as caligraph.org or AI-improved abstracts.
2. Community Link Contributions for inclusion in the main graph.
3. RDF profiles for DBpedia Users and Members (FOAF, Schema.org, WebID) via Databus Accounts (including publication of expertise).
4. Dockerized RDF Tool Deployment so you can automatically load DBpedia and other RDF data into your favorite RDF tools via Databus collections. Our Databus-powered Virtuoso SPARQL Endpoint Quickstart Docker has already been deployed over 150k times! 

We do hope we will meet you and some new faces during our events next year. The 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 a tutorial at the LREC-COLING 2024 conference and a meeting at SEMANTiCS, Sep 17-19, 2024, conference in Amsterdam, Netherlands.

In the upcoming blog series, we like to take you on a retrospective tour through 2021, giving you insights into a year with DBpedia. In the following we will also highlight our past events. 

A year with DBpedia – Retrospective Part 1

Our New Face 

On January 28, 2021, the new DBpedia website went online. We worked on the completion for about a year and at the beginning of 2021 we proudly presented the new site to the community and our members. We used the New Year’s break 2022/2021 as an opportunity to alter the layout, design and content of the website, according to the requirements of the community and our members. We’ve created a new site to better present the DBpedia movement in its many facets. We additionally integrated the DBpedia blog on the website, a long overdue step. So now, you have access to all in one spot. Read our announcement here.

Giving knowledge back to Wikipedia: Towards a Systematic Approach to Sync Factual Data across Wikipedia, Wikidata and External Data Sources

Since the beginning of DBpedia, there was always a strong consensus in the community, that one of the goals of DBpedia was to feed semantic knowledge back into Wikipedia again to improve its structure and data quality. It was a topic of many discussions over the years about how to achieve this goal. We received a Wikimedia Grant for our project GlobalFactSyncRE and re-iterated the issue again. After almost two years of working on the topic, we would like to announce our final report. We submitted a summary of this report to the Qurator conference and presented it there on February 11, 2021:

Towards a Systematic Approach to Sync Factual Data across Wikipedia, Wikidata and External Data Sources. Sebastian Hellmann, Johannes Frey, Marvin Hofer, Milan Dojchinovski, Krzysztof Wecel and Włodzimierz Lewoniewski.

Read the submitted paper here.

DBpedia Tutorial at the Knowledge Graph Conference

On May 4, 2021, we organized a tutorial at the Knowledge Graph Conference 2021. The tutorial targeted existing and potential new users and developers that wish to learn how to replicate our infrastructure. During the course of the tutorial the participants gained knowledge about the DBpedia Knowledge Graph (KG) lifecycle, how to find information, access, query and work with the DBpedia KG and the Databus platform as well as services (Spotlight, Archivo, etc). If you missed our presentations, please check our slides here.

Most Influential Scholars

DBpedia has become a high-impact, high-visibility project because of our foundation in excellent Knowledge Engineering as the pivot point between scientific methods, innovation and industrial-grade output. The drivers behind DBpedia are 4 out of the TOP 10 Most Influential Scholars in Knowledge Engineering and the C-level executives of our members. Check all details here https://www.aminer.cn/ai2000/ke.  

Google Summer of Code and DBpedia

For the 10th year in a row, we were part of this incredible journey of young ambitious developers who joined us as an open source organization to work on a GSoC coding project all summer. Even though Covid-19 changed a lot in the world, it couldn’t shake GSoC. If you want to have deeper insights in our GSoC student’s work you can find their blogs and repos on the DBpedia blog.

DBpedia Global: Data Beyond Wikipedia

Since 2007, we’ve been extracting, mapping and linking content from Wikipedia into what is generally known as the DBpedia Snapshot that provided the kernel for what is known today as the LOD Cloud Knowledge Graph. On June 7, 2021, we launched DBpedia Global. It’s a more powerful kernel for LOD Cloud Knowledge Graph that ultimately strengthens the utility of Linked Data principles by adding more decentralization i.e., broadening the scope of Linked Data associated with DBpedia. Think of this as “DBpedia beyond Wikipedia” courtesy of additional reference data from various sources. Get more insight and read the announcement on the DBpedia blog. 

In the upcoming blog post after the holidays we will give you more insights in the past events and technical achievements. We are now looking forward to the year 2022. We plan to have meetings at the Data Week 2022 in Leipzig, Germany and the SEMANTiCS 2022 conference in Vienna, Austria. Furthermore, we will be part of the WWW’22 conference and organize a tutorial. 

We wish you a merry Christmas and a happy new year. In the meantime, stay tuned and check our Twitter, Instagram or LinkedIn channels. You can subscribe to our Newsletter for the latest news and information around DBpedia.
