Query expansion is a technique of information retrieval system which considered to the context of the user's queries in order to improve the retrieval effectiveness. There are several method expansion methods have been investigated. An ontology-based approach is one of the expansion approaches which used as knowledge-based for searching. This paper proposed an ontology-based query expansion using a concept of the combination of an IR technique and association rule mining to examine and evaluate of an agricultural expert retrieval systems. An association rule mining is applied in the inference engine in order to optimize the user's queries. A set of inference rules are also created to support the expertise retrieval task. The result set is depends on the new query which expands from user's queries as keywords using an agricultural ontology structures. The experts who have expertise in topics or keywords, type of plants and problem solving are the elements of the ontology and will be used to search the relevant publications. The experiments were conducted using publications from collections of the Thai National AGRIS center. The results show that the improvement of this expansion method yields better performance than using basic query expansion search with the F-measure equal to 98.87%.
