News and Updates on the KRR Group
Header image

The KR&R group investigates modelling and representation of different forms of knowledge and reasoning, as found in a large variety of AI systems. We have an interest in both applications and theory. We study theoretical properties of knowledge representation and reasoning formalisms, but are also involved in developing practical knowledge-based systems. Recently, we have been very active in developments around the Semantic Web.

Posts on this website are continuously aggregated from project and member blogs.

Laurens Rietveld graduated on 9th of March 2016. Find out more about his PhD project here.

On Wednesday March 9th, the Knowledge Representation and Reasoning group of the VU University organises a seminar preceding the PhD Defence of Laurens Rietveld. You are cordially invited to attend both the seminar and the defence of Laurens.

The seminar takes place at 13.00-14.30 in the VU University Amsterdam, main building, EZ – HG-03A10 Agora 4. The defence of Laurens Rietveld on the topic of Publishing and Consuming Linked Data starts at 15.45 in the Aula.

Title: Linking Data on the Web and within Enterprises

Abstract:
In the last years, the Linked Data concept gained wide attention for integrating distributed, heterogeneous data on the Web and within enterprises. In this talk, we discuss some crucial research and technology challenges of the Linked Data management life-cycle including extraction, linking, quality assurance, authoring and visualization. We look at existing and promising future Linked Data applications in the Digital Humanities/Cultural Heritage, Enterprise Data and Internet of Thing/Industry 4.0 domains.

Bio:
Sören heads the Enterprise Information Systems group at the computer science department at University of Bonn. He is also member of the leadership council of Fraunhofer-Insitute for Intelligent Analysis and Information Systems (IAIS) and scientific head of the Fraunhofer IAIS department Organized Knowledge. Before joining University of Bonn and Fraunhofer IAIS in 2013, Sören founded AKSW research group at University of Leipzig and worked at TU Chemnitz as well as University of Pennsylvania.

Title: Knowledge Representation on the Web revisited: the case for Prototypes

Abstract:
In recent years RDF and OWL have become the most common knowledge representation languages in use on the Web, propelled by the recommendation of the W3C. In this talk I will report on some work to develop a case for using a different approach for representing knowledge on the Web. I argue, that an approach, based on Prototypes, is more suitable than the currently available paradigms for representing knowledge on the Web. I will discuss requirements and design principles for Knowledge Representation based on Prototypes on the Web, after which I propose a formal syntax and semantics. I report on an implementation and on the usability of the system. The presented work is jointly done with Michael Cochez (University of Jyvaskyla).

Bio:
Prof Stefan Decker is a professor at RWTH Aachen University and a Director of the Fraunhofer Institute for Applied Information Technology (FIT). He had a Chair at the National University of Ireland, Galway in conjunction with the Directorship of the Digital Enterprise Research Institute (now Insight), a Research Assistant Professor position at the Information Sciences Institute of the University of Southern California, and positions at Stanford University and University of Karlsruhe. His current research interests include the Semantic Web, Linked Data, Open Data, ontologies and semi-structured data, and applications for Digital Humanities and the Life Sciences.

CTcue  a company that develops technology for help recruit patients for medical trials is one of the 10 finalists in the Amsterdam Science & Innovation Award 2015.
CTcue has collaborated with our group, has employed one of our PhD students, and their product and services are in part based on our publications, such as:

NWO has awarded 12M Euro to CLARIAH, a project to build a digital infrastructure for software, data, enrichment, search and analytics in the Humanities.  Frank van Harmelen, Maarten de Rijke en Cees Snoek are among the 9 scientists that form the core team of the project. See http://clariah.nl/, http://bit.ly/TERNC0, http://bit.ly/1mWtnje for more details.

Recently the Linked Data Benchmark Council (LDBC) launched its portal http://ldbcouncil.org

LDBC is an  organization for graph and RDF data management systems benchmarking that came out of a EU PF7 project by the same name (ldbc.eu).

The LDBC will survive the EU project and be industry supported and operate with ldbcouncil.org as its web presence.

Also, LDBC announced public drafts of its two first benchmarks. Public draft means that implementations of benchmark software and technical specification documents are available, and ready for public testing and comments. The two benchmarks are

– the Semantic Publishing Benchmark (SPB – http://ldbcouncil.org/benchmarks/spb) which is based on the BBC use case and ontologies, and

– the Social Network Benchmark (SNB – http://ldbcouncil/benchmarks/snb) on which an interactive workload has been released. Later, a Business Intelligence and a Graph Analytics will follow on this same dataset. The SNB data generator was recently used in the ACM SIGMOD programming contest, which was about graph analytics.

The ldbcouncil.org website also holds a blog with new and technical backgrounds of LDBC. The most recent post is about “Choke-Point based Benchmark Design”, by Peter Boncz.
