Aerospace Information System based on Semantic Technonogies and Ontology Management - A Web Portal for Semantic Search and Document Categorization

This paper describes a semantic search tool based on our experience in using a new lexical domain ontology for aerospace integrated with an open source general purpose ontology to support aerospace engineers in the timely semantic retrieval of the knowledge. The semantic search module represents an integrated tool dedicated to the semantic search, extraction and classification of information and knowledge in aerospace domain. It describes the implementation of a disambiguation algorithm based upon these ontologies and a new interesting graphical user interface for semantic searches is presented. Furthermore, next to the domain ontology, a taxonomy for classifying aerospace documents is also proposed. The document classification algorithm that leverages the deep integration between the proposed lexical domain ontology and taxonomy is also described. Finally, some considerations about the usage of the semantic search module by the side of domain experts, semantic experts or common users are reported.
