Clustering-based patent map making and representing method

Abstract

The invention provides a clustering-based patent map making and representing method, which comprises the following steps: extracting features by adopting a text mining technology, mapping unstructuredpatent text information into a low-dimensional space, clustering by adopting a CFSFDP algorithm, and analyzing the features of patent texts in the same cluster by combining unstructured information,therefore, the patent map represented by the directed graph is obtained, and the obtained result can reflect the technical development process of the target technical field more truly and accurately.

Description

technical field [0001] The invention relates to the field of patent map production, in particular to a patent map production and representation technology based on a clustering algorithm. Background technique [0002] Patent map is a form of presenting and summarizing various patent-related information and information, that is, statistical analysis, analysis and arrangement of patent information in the target field, and the results are made into chart information with a similar map pointing function. Compared with other patent management analysis methods, the patent map is more comprehensive, and its presentation form makes it more intuitive and comprehensive, and it is also more convenient and efficient in terms of analysis and utilization. The patent map can point out the direction of technological development for enterprises, and help enterprises analyze and summarize the distribution and use of technologies, thereby helping enterprises to carry out effective intellectual...

Problems solved by technology

Subsequently, this technology was also introduced into South Korea, the United States, Singapore and other places, and has been widely used. However, our country has little research and application on it, which is not conducive to the development of my country's patented technology and industry.

The reason for this situation is that on the one hand, insufficient attention has been paid to it, and on the other hand, it is also because of the technical difficulty in making patent maps

[0004] The amount of information involved in the patent map is huge, and the compilation, analysis and production are extremely cumbersome. For ordinary enterprises, such a task is difficult to complete

[0005] In this field, the current method of making patent maps is mainly to first formulate relevant search strategies according to the project fields that require patent analysis, and use this strategy to conduct blanket search and comparison of patent management maps, patent technology maps, patent rights maps, etc. , investigation, and finally summarized into a patent map, which is labor-intensive, time-consuming and labor-intensive; in addition, both structured and unstructured projects are not fully utilized in the production process and presentation of patent maps, and only one of them is used to make patent maps. Not using the other or just adding another information on the completed patent map
