1 Introduction
The rapid development of Internet application has greatly increased the information available on the
Internet, causing it difficult to carry out the first step towards E-commerce - ECommerce information retrieval.
The problem how to efficiently retrieves valuable information from huge mounts of information remains to be solved. Traditional information retrieval depends on techniques such as contents, indexes, and keywords, with advantages of being simple and speedy, while the
primary drawback is that those techniques could not mine the inner relationships among information and the retrieval results could not precisely and comprehensively meet user demands.
Since there being lack of a single semantic description for the entire internet information
resources, users could not properly locate the relevant contents and services [1].
The problem to realize intelligent business information retrieval relies on making the meaning of the internet information resources understandable by the retrieving system and facilitating the semantic integration of information resources.
Based on WordNet, Ray Richardson proposed the knowledge-based information retrieval method[2] by calculating the semantic distance between concepts, while the distance could be used to compute the similarity between the inquiring conditions and web pages.
Though the precision and recall rates on information retrieval are not so idealistic, this method has
provided a direction for semantic information retrieval.
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.
