Check out our comprehensive introduction to Knowledge Graphs, aimed at both newcomers and non-newcomers alike! (arxiv.org/abs/2003.02320) The paper arose from a Dagsthul seminar held in September 2018 and draws together diverse topics & perspectives regarding Knowledge Graphs.

In a recent @dagstuhl seminar we developed a research roadmap towards Computer-Using Personal Agents, which automate complex tasks like today's Computer-Using Agents, but include context via controlled access to personal knowledge graphs. Our vision paper: openaccess.city.ac.uk/id/eprint/34788

"Large Language Models, Knowledge Graphs [such as Wikidata] and Search Engines: A Crossroads for Answering Users' Questions" arxiv.org/abs/2501.06699… KG advantages: "precise, transparent and deterministic" disadvantages: "weaker coverage and freshness", lack "nuance and diversity"

@danbri @vrandezo For sure! Two +'s is not intended to mean full marks. Probably no technology achieves full marks on any category (the closest being LLMs for usability and SEs for efficiency?). The intention is to highlight at most two key points (be they positive/negative).</fig-leaf>

@aidhog @vrandezo I look forward to reading, and haven’t yet, so maybe this is unfair: giving KGs only full positive marks for “correctness” seems immodest and downplays the arduous and expensive work of curation and integration needed. Hopefully AI can help there a bit too?

How can #LLMs, Knowledge Graphs and Search Engines be combined to best serve users? What are the strengths and limitations of these technologies? See arxiv.org/abs/2501.06699 for discussion, coautored with Luna Dong, @vrandezo and Gerard Weikum.

🎉¡Hoy conmemoramos 50 años del #dccuchile! Medio siglo en el que hemos sido testigos del crecimiento de generaciones de estudiantes, académicos y profesionales que han dejado una huella imborrable. ¡Agradecemos a todos/as quienes han sido parte de esta historia! 🎓💻

To finish the closing session, #ISWC2025 General Chair @AnLiGentile and Local Chair @takechan2000 announced that ISWC will go to Nara, Japan next year! You can soon find details on the official website iswc2025.semanticweb.org

Best Paper Award, Research track was awarded to Kate Lin, Tarfah Alrashed and Natasha Noy for their work "Relationships are Complicated! An Analysis of Relationships Between Datasets on the Web". Big Congrats!

Best Student Paper Award, Research Track went to Benjamín Farías, Wim Martens, Carlos Rojas and Domagoj Vrgoč for "PathFinder: Returning Paths in Graph Queries." Well deserved!

With a little bit of improvisation, we had a quite different closing session for #ISWC2024 where our General Chair @aidhog and the track chairs shared some closing words and announced the award winners
