基于概念格的信息检索及其树形可视化
Information retrieval based on concept lattice and its tree visualization
摘要
Abstract
Concept lattice as a significant data representation of formal concept lattice has been widely used in knowledge acquisition and information retrieval for embodying the generalization and specialization relationship vividly and succinctly among concepts. In the process of using concept lattice for retrieval, the presenting structure of concept lattice is easily making edges crossover as the number of concepts and their relationships grow significantly, giving rise to confused vision and target information omission. To solve this problem, combining the advantages of concept lattice in information retrieval with the regularity of tree structure in visualization, firstly it stores data information using concept lattice structure, then changes the lattice structure into tree structure before displaying to the users, so that users can not only search target information through multiple paths but also have a clear browsing. Finally, the method is applied to music classification and retrieval, and experimental result shows that the method is efficient and effective.关键词
