A Methodology to Create Ontology-Based Information Retrieval Systems
نویسندگان
چکیده
Modern information retrieval systems need the capability to reason about the knowledge conveyed by text bases. In this paper a methodology to automatically create ontologies and class instances from documents is proposed. The ontology is defined in the OWL semantic web language and it is used by a logic programming framework, ISCO, to allow users to query the semantic content of the documents. ISCO allows an easy and efficient integration of declarative, object-oriented and constraint-based programming techniques with the capability to create connections with external databases.

Public Transport Ontology for Passenger Information Retrieval
Passenger information aims at improving the user-friendliness of public transport systems while influencing passenger route choices to satisfy transit user’s travel requirements. The integration of transit information from multiple agencies is a major challenge in implementation of multi-modal passenger information systems. The problem of information sharing is further compounded by the multi-l...
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...

متن کاملSemantic Enrichment of a Web Legal Information Retrieval System
Intelligent text information retrieval systems need the capability to deal with the semantics of the content of their text bases. In order to satisfy this requisite it is necessary to extract semantic information from the documents and to be able to make inferences about it. A methodology to semi-automatically transform a traditional web IR system into a semantic aware one is proposed. The meth...
