Method for determining technological development vein diagram

Abstract

The invention discloses a method for determining a technological development vein diagram. The method comprises the steps that important patent literature is found in a background according to a specific index, and then co-occurrence analysis method selection is carried out; one of co-citation analysis, co-classification analysis and co-word analysis is selected; if a co-citation analysis method is selected, a technological development vein is analyzed according to a quoting relation and the time dimension; if co-classification analysis or co-word analysis is selected, the technological development vein is determined according to the technical relation correlation degree on the time relationship and the time dimension. The technological development vein diagram can reflect the research hotspot and the core technology in a certain technical field, the quoted development trend of the patented technology is accurately grasped, therefore, change information of the technology frontier can be effectively acquired, and important significance is achieved.

Description

technical field [0001] The invention relates to the field of patent information research, in particular to a method for determining a technological development context map. Background technique [0002] As patent information, it is not only simple collation and processing, but more importantly, deep processing to obtain deep information. As a patent information research, the four main elements of technology, people, time and place are generally used to carry out two-dimensional and multi-dimensional combination, and then conduct qualitative, quantitative, vector, model and mathematical correlation analysis to obtain implicit technical information. , Business intelligence, rights intelligence and related laws. [0003] The research method of technological development context is to select the types of patent documents related to the research topic, statistically analyze the technical problems solved in the patent documents in a certain period, and form technical groups of dif...

AI Technical Summary

Problems solved by technology

Derwent manual codes can be used to study the network structure between technologies and technologies by using the method of common class analysis. Through detailed analysis of the technology network, the key technologies in each technology cluster can be further judged, but there is a certain calculation volume and complexity

However, starting from the patent classification number to discuss the technical relevance of the field, due to the extremely limited information capacity of the patent classification number, it is difficult to accurately reflect the true relationship between technologies

[0007] The co-word analysis uses the co-occurrence of words or phrases to describe the relationship between concepts, which has better applicability, but it is rare in patent measurement. This is because there are no keywords in patent documents, so the word still a difficulty

Although the existing Derwent analyst software can truncate the patent documents in the Derwent patent database, to select the words that can reflect the relevant technology from the massive vocabularies intercepted requires the analyst not only to have intelligence In addition to analytical ability, he also has high professional knowledge, which brings certain difficulties to the analysis
