Recent Developments in Bridging the Semantic Gap Problem

Abstract: In this talk, I will present a summary of my PhD thesis which is about bridging the semantic gap between sensor data and ontological knowledge. The focus will be on the recent developments in heterogeneous knowledge integration as a solution for the semantic gap issue. I will also introduce the two research projects: Semantic Robot and E-care@home, with the goal of addressing the knowledge integration problem. In Semantic Robot, we are aiming to provide a semantic layer to a 3D topographic map and making the objects in the 3D map reasoning ready for different purposes such as querying and navigation. Likewise, in Ecare@home which is a Swedish interdisciplinary distributed research environment, our focus is on the development of methods that provide interpretation of the heterogeneous data coming from different types of sensors in conjunction with both medical and environmental knowledge in order to provide e-services for the elderly residing in their homes.

Survey on Ontology Engineering tooling

Posted on by

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.

Even more LiU Research at ISWC 2016 – Ontology Design Patterns

Posted on by

In addition to the work mentioned in a previous post about ISWC, the LiU Semantic Web research team has also been very active in the Ontology Design Patterns (ODPs) sub-community at ISWC.

On Monday (October 17), Karl Hammar co-arranged the tutorial session Ontology Design Patterns for Linked Data Publishing. The tutorial was very well-received, with over 30 participants learning about ODP theory and practice, and evaluating Karl’s XD for WebProtégé ODP tooling.

On Tuesday (October 18), Karl also co-arranged the 7th Workshop on Ontology and Semantic Web Patterns, at which he also presented two papers: Template-Based Content ODP Instantiation and How to Document Ontology Design Patterns. In total there were twelve presentations given at the workshop, two keynote talks, and a town hall meeting discussing future directions of research and other issues of weight to the ODP community. Approximately 25 people attended the workshop, and the quality of the work presented and of the subsequent discussions was excellent.

HannesEbnerOn Monday next week, October 31, Hannes Ebner of MetaSolutions AB will give a talk in our series of Semantic Web seminars. The title of his talk is:

From Research to Business – Enabling Agile Information Management with Linked Data

Abstract: MetaSolutions was founded in 2011 as a spin-off from research on Web Architecture and Linked Data. Even today the Linked Data technology stack builds the foundation of the company’s product platform that allows organisations to manage their information in a more agile way. Hannes Ebner, one of the two founders, will talk about how a product emerged from research prototypes, which common business problems the company tackles, and how the application of Linked Data became a competitive advantage.

Time and date: 11am, October 31, 2016

Location: Campus Valla, Building B, Room “Charles Babbage”
