چکیده

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 employs novel ontology projection techniques to enable faceted navigation for OWL 2. SemFacet relies on PAGOdA and HermiT for logical reasoning and on JRDFox and Sesame for storing and querying RDF triples.

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...

SemFacet: Faceted Search over Ontology Enhanced Knowledge Graphs

In this demo we present the SemFacet system for faceted search over ontology enhanced Knowledge Graphs (KGs) stored in RDF. SemFacet allows users to query KGs with relatively complex SPARQL queries via an intuitive Amazon-like interface. SemFacet can compute faceted interfaces over large scale RDF datasets by relying on incremental algorithms and over large ontologies by exploiting ontology pro...

Faceted search over RDF-based knowledge graphs

Knowledge graphs such as Yago and Freebase have become a powerful asset for enhancing search, and are being intensively used in both academia in industry. Many existing knowledge graphs are either available as Linked Open Data, or they can be exported as RDF datasets enhanced with background knowledge in the form of an OWL 2 ontology. Faceted search is the de facto approach for exploratory sear...

Querying Ontologies in Relational Database Systems

In many areas of life science, such as biology and medicine, ontologies are nowadays commonly used to annotate objects of interest, such as biological samples, clinical pictures, or species in a standardized way. In these applications, an ontology is merely a structured vocabulary in the form of a tree or a directed acyclic graph of concepts. Typically, ontologies are stored together with the d...

بررسی هستان شناسی های توسعه یافته مبتنی بر اصول هستان شناسی های منبع باز زیست پزشکی

Background and Aim: Ontologies facilitate data integration, exchange, searching and querying. Open Biomedical Ontologies (OBO) Foundry is a solution for creating reference ontologies. In this foundry, the design of ontologies is based on established principles which allow for their interactions as a single system. The purpose of this study is to determine the main features of ontologies develop...
