A Semantic Search Engine for the International Relation Sector

Abstract

The Royal Institute Elcano 1 (Real Instituto Elcano) in Spain is a prestigious independent political institute whose mission is to comment on the political situation in the world focusing on its relation to Spain. As part of its dissemination strategy it operates a public website. In this paper we present and evaluate the application of a semantic search engine to improve access to the Institute's content: instead of retrieving documents based on user queries of keywords, the system accepts queries in natural language and returns answers rather than links to documents. Topics that will be discussed include ontology construction, automatic ontology population, semantic access through a natural language interface and a failure analysis.

PANTO: A Portable Natural Language Interface to Ontologies

“…POS tags, chunks, etc. Rodrigo et al tried to break down the query into words and form a formal query with words in their semantic search engine for the international relation sector [21]. Kang et al have also formed the SQL query with keywords in [22].…”

“…Kang et al have also formed the SQL query with keywords in [22]. As it is summarized by the authors in [21], "...the query construction is at present the weakest link in the chain...". Since PANTO combines the OntoTriples and the modifiers generated from the parse tree and the Lexicon, it can easily constructs the SPARQL query.…”
