Next week, the 27th edition of The Web Conference (earlier called International World Wide Web Conference – WWW) will take place in Lyon, France, and different results of Semantic Web research at LiU will be present at the conference.

First, there is a research paper in the main research track of the conference by our Olaf Hartig and Jorge Pérez from the Universidad de Chile. The title of the paper is “Semantics and Complexity of GraphQL.

Additionally, Olaf will give an invited talk in the Web Stream Processing workshop at the conference. While the exact title of the talk is yet to be decided, the talk will present recent work about the RDF*/SPARQL* Approach to Statement-Level Metadata in RDF.

Find Olaf and talk to him if you also happen to be in the conference; he will be happy to tell you more about his research, as well as our other Semantic Web related research at LiU.


 

Survey on Ontology Engineering tooling

Karl Hammar is running a survey on user preferences with regard to ontology tooling, specifically tooling supporting Ontology Design Patterns. As an incentive to take part, a lottery will be held in a few weeks, at which Amazon gift cards to the amount of 50 USD each (or the equivalent in local currency for local Amazon sites), will be awarded to one out of every ten participants in this survey.

Any SemWeb people who are interested in participating in the survey and the lottery are welcome to do so: just follow the instructions below.

Survey Instructions

  1. Surf to http://wp.xd-protege.com, where a customized WebProtégé environment awaits. Register for an account and start a new project.
  2. Look at the scenario described at https://goo.gl/5cXeUP and the corresponding data sets at http://karlhammar.com/ontologies/2016/10/ISWC2016TutorialData.zip
  3. In the WebProtégé install mentioned above, under the tab ”Design Patterns”, check out the listed ontology design patterns from the scenario description.
  4. Try to model a couple of the competency questions from that scenario by way of instantiating ontology design patterns. To do so, find a pattern that you wish to use in the browser, and click the ”Use this pattern” button at the top of the pattern description page, which starts up a pattern instantiation wizard. It should be enough if you run through this wizard once or twice.
  5. Finally, once you’ve run through the wizard once or twice (which should hopefully take no more than 10-15 minutes), please fill out the survey at https://goo.gl/I1MWT4.

Semantic Web research at LiU

The Semantic Web is an extension of the traditional Web towards having machine processable content and interlinked data on the Web, with well-described semantics.

Ideally we would be able to view the whole Web as a large set of interconnected databases, which can be queried and browsed by software systems as well as human users. Semantic Web research at LiU includes areas such as ontologies and ontology engineering (ontology design patterns, ontology alignment and completion, ontology and alignment visualisation), graph databases and triple stores, querying the Web of data, RDF stream processing and complex event processing, as well as applications of these technologies in a number of fields, including open data, security, decision support systems, e-health and e-science, etc.

The aim of this blog is to report on the activities of our research group, and make results accessible to a wider audience.
