چکیده

Data on the Semantic Web is semi-structured and does not follow one fixed schema. Faceted browsing [23] is a natural technique for navigating such data, partitioning the information space into orthogonal conceptual dimensions. Current faceted interfaces are manually constructed and have limited query expressiveness. We develop an expressive faceted interface for semi-structured data and formally show the improvement over existing interfaces. Secondly, we develop metrics for automatic ranking of facet quality, bypassing the need for manual construction of the interface. We develop a prototype for faceted navigation of arbitrary RDF data. Experimental evaluation shows improved usability over current interfaces.

Querying Life Science Ontologies with SemFacet

Faceted search is the de facto query paradigm in e-commerce and it has been recently adapted for the Semantic Web. In this demonstration we present our faceted search system SemFacet and show how it can enhance access to RDF and OWL 2 datasets and OWL 2 ontologies in the domain of life sciences. SemFacet combines keyword and faceted search and it is based on a solid theory, in particular it emp...

Faceted Search over OWL 2 Life Science Datasets and Ontologies with SemFacet

Faceted search is the de facto query paradigm in e-commerce applications. Recently this approach was adapted to the context of the Semantic Web. In this demonstration we present our faceted search system SemFacet and show how it can enhance access to RDF and OWL 2 datasets and OWL 2 ontologies in the domain of life sciences. SemFacet combines keyword and faceted search and it is based on a soli...

Reconciling faceted search and query languages for the Semantic Web

Faceted search and querying are two well-known paradigms to search the Semantic Web. Querying languages, such as SPARQL, offer expressive means for searching RDF datasets, but they are difficult to use. Query assistants help users to write well-formed queries, but they do not prevent empty results. Faceted search supports exploratory search, i.e., guided navigation that returns rich feedbacks t...

Scalewelis: a Scalable Query-based Faceted Search System on Top of SPARQL Endpoints

This paper overviews the participation of Scalewelis in the QALD-3 open challenge. Scalewelis is a Faceted Search system. Faceted Search systems refine the result set at each navigation step. In Scalewelis, refinements are syntactic operations that modify the user query. Scalewelis uses the Semantic Web standards (URI, RDF, SPARQL) and connects to SPARQL endpoints.

FacetOntology: Expressive Descriptions of Facets in the Semantic Web

The formal structure of the information on the Semantic Web lends itself to faceted browsing, an information retrieval method where users can filter results based on the values of properties (“facets”). Numerous faceted browsers have been created to browse RDF and Linked Data, but these systems use their own ontologies for defining how data is queried to populate their facets. Since the source ...
