To make information retrieving more efficient and maximally realize metadata sharing and reusing, this paper proposes using EIM and EIM-based semantic similarity function to process semantic information comparison among words, making the system with a relatively better semantic information expression capability for the business domain.
This similarity algorithm could be implemented in business information retrieving system, and experimental results show that this algorithm has better precision and recall rates for business information retrieving and effectuates semantic information service of business domain.
