    摘要: Since most search engines retrieve documents strictly based on keywords, they cannot obtain other content that is similar in idea but different in keywords. Therefore, semantic query expansion is very important and ontology is a critical foundation for supporting semantic query expansion. Ontology has been used in Information Retrieval, Data Category, Library Sciences and Medical Sciences; however, its use is rare in the Military Domain. There are two purposes for this research. The first is to use a `Military Dictionary` database as a fundamental and combine it with the procedure of formal concept analysis to automatically construct the relationship between military ontology and vocabulary concepts. The second is to use military news from the `Defense Technology Military Database` as a training data resource, to design a novel query expansion with the Keyword to Formal Concept Query Expansion (K2FCQE) algorithm and then to proceed query mode verification. The results of this research verify that the K2FCQE is more efficient than other query expansions. © 2014 IEEE.
