RESEARCH ON CONSTRUCTION OF PATENT DYNAMIC TECHNOLOGY EFFECT MATRIX

摘要

The analysis of patent effect matrix can reveal the relationship between technology and effect in the patent literature, resolve obscure information content and potential technical characteristics, and find out technical focus and blank spots to avoid technology minefields. The construction of effect matrix is the prerequisite for the analysis of patent effect matrix. Currently, it needs the efforts of the intelligence analyst, the domain expert or the enterprise technician to interpret each patent document in detail so as to understand the technical and utility information. In view of this, this paper puts forward a method of constructing dynamic technology effect matrix based on domain ontology, information extraction, and semantic annotation and so on. And the implementation and application in the chemical field show our method can achieve good results.
