Abstract :
The purpose of this paper is to improve retrieval efficiency to muli-attribute instance knowledge. The paper expressed multi-attribute instance knowledge as a model with multi-attribute and tree structure, which synthetically apply similarity calculation method of value type attribute and of imprecise value type attribute and of word type attribute, which optimized step of calculation and order of calculation, and improved retrieval efficiency.
