    Ontogator: Combining View-And Ontology-Based Search With Semantic Browsing

    The authors show how the benefits of the view-based search method, developed within the information retrieval community, can be combined and extended with the benefits of ontology-based annotations and search, developed within the Semantic Web community. As a proof of the concept, they have implemented an ontology- and view-based image...

    Testing and Debugging Techniques for Answer Set Solver Development

    This paper develops automated testing and debugging techniques for answer set solver development. The paper describes a flexible grammar-based black-box ASP fuzz testing tool which is able to reveal various defects such as unsound and incomplete behavior, i.e. invalid answer sets and inability to find existing solutions, in state-of-the-art answer...

    Floating Content: Information Availability in Urban Environments

    Content sharing via the Internet is a widespread means for people to foster their relationships irrespective of physical distance. While network-based social applications are essential to overcome distances and connect people around the world, relying on infrastructure services for location-aware services may often not be desirable. In this paper, the...

    Parameter-Free Spatial Data Mining Using MDL

    Consider spatial data consisting of a set of binary features taking values over a collection of spatial extents (grid cells). It proposed a method that simultaneously funds spatial correlation and feature co-occurrence patterns, without any parameters. In particular, it employs the Minimum Description Length (MDL) principle coupled with a natural...
