摘要：Organizational knowledge structure is a reflection of organizational knowledge system. In this paper, we study organizational knowledge structure's construction based on patent documents using text mining method. Its construction process is as follows: Firstly, patent documents of organization are collected and preprocessed. Secondly, key terms are extracted from patent documents as knowledge elements using a merge algorithm, and synonymous terms are merged using a Chinese thesaurus - TongYiCi CiLin and pattern matching. Finally, similarity between terms is counted based on co-occurrence of terms, and hierarchical relationships between terms are built using hierarchical agglomerative clustering algorithm (HAC), and then organizational knowledge structure is formed through visualization.
