In information query process, query expansion can effectively resolve the problem related to low
query efficiency caused by ambiguous short query terms. This study proposes a query expansion approach
based on ontology and local context analysis. Ontology-based query expansion enables the addition of
standardized descriptive information for search query, while local context analysis, through document library
analysis, offers more relevant information for inquiry. We combine advantages of the two methods to expand
the keywords semantically. Experimental analysis indicates that our method can effectively improve the search
recall and precision.
Key words: Local context analysis, ontology, query expansion, relevance calculation, , ,
