Research of Information Retrieval Based on Web Semantic Similarity
Yang‐Xin Yu, L.Y. Wang · Applied Mechanics and Materials · 2011
An important research of information retrieval technology is how to express the intention of users accurately and make a sensible judgment on the semantic similarity between conceptual entities. A scheme is presented to calculate the semantic similarity, which takes multi-inheritance of entities and property values into consideration , and then optimizes the computing process based on the tree structure of inheritance relationship. When the instance multiple inheritances are relatively complex, the accuracy rate is more pronounced than existing methods. The experimental results show that the scheme proposed in this paper can calculate semantic similarity more accurately even in ontology-based knowledge base.
