Querying the Semantic Web with Racer + nRQL
نویسندگان
چکیده
This paper introduces a description logic query language for retrieving A-box individuals that satisfy specific conditions. The language is substantially more expressive than traditional concept-based retrieval languages offered by previous description logic reasoning systems. The new language is implemented in the Racer system. We demonstrate the applicability of nRQL (new Racer Query Language) to OWL semantic web repositories and evaluate the performance of the current state of the art query answering engines for description logics using the Lehigh University Benchmark (LUBM).

Development of a server to support the formal semantic web query language OWL-QL
In this abstract we present a server that supports OWL-QL query-answering dialogues by making use of the reasoning capabilities of the DL reasoner Racer. Currently, users can use Racer to query an OWL knowledge base using nRQL or DIG. Our primary goal in developing an OWL-QL server is to oer as many as possible reasoning functions of Racer in the standard query language OWL-QL. This rst version...
متن کاملQuery Answering Systems in the Semantic Web
In this paper a new query answering system is presented for querying knowledge bases in the Semantic Web. The implementation follows the DAML+OIL Query Language Abstract Speci cation (DQL) and supports acyclic conjunctive queries. The system uses a Description Logic (DL) reasoner to answer the queries and the conjunctive queries are transformed into DL retrieval or boolean queries. After the in...
متن کاملUsing Selectional Restrictions to Query an OWL Ontology
This paper discusses the linguistic module of an Ontology Natural Language Interaction System that is based on semantic restrictions. The system, called ONLI, takes as input questions in unrestricted natural language, translates them into nRQL, an extension to the RACER ontology query language, then generates answers as returned by the RACER ontology reasoning server. Translation into nRQL is d...
متن کاملGraphical Interfaces for Racer: Querying DAML+OIL and RDF Documents
In this paper, we introduce RICE, a graphical application for interacting with the description logic inference server Racer. Comparing RICE with OilEd, we address the problem of visualizing and querying A-boxes w.r.t. predefined Tboxes. We discuss examples with T-boxes and A-boxes that are derived from DAML+OIL and RDF documents, respectively. Thus, the visualization tools discussed in this pap...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
