Patent display method based on innovation direction tree

Abstract

The invention provides a patent display method based on an innovation direction tree, and the method comprises the steps: setting an innovation direction keyword as a root node, and retrieving a patent database; performing text clustering on the retrieved files, and setting various common concepts as primary child nodes according to clustering results; performing text clustering on the newly obtained class-containing files associated with the sub-nodes, and setting a common concept of each subclass as a next-level sub-node belonging to the corresponding sub-node according to a clustering result; and circulating the step S3 until the distance between the newly obtained file in the subclass associated with each child node and the common concept of the subclass is smaller than or equal to a preset concept distance threshold. According to the patent display method based on the innovative direction tree, the retrieval results are classified and displayed through the tree diagram, automaticclassification of the retrieval results is achieved, a user can conveniently and finally overview and screen retrieval files, and therefore retrieval efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to a method for displaying patents based on an innovation direction tree. Background technique [0002] With the development of science and technology, people pay more and more attention to intellectual property protection, and patent is one of the most important means in intellectual property protection. Since most new technologies appear in the form of patents at the beginning, the patent database centrally stores a large amount of the latest technical information. By using the patent database, you can learn about the latest technologies in various industries, thereby avoiding repeated development, avoiding infringement, and even analyzing the technology research and development status and strategies of competitors, as well as the development of the entire technology industry. [0003] However, patent research is a relatively time-consuming and laborious work. Beca...

Problems solved by technology

[0004] Although the national patent offices of the open patent databases provide convenient patent search engines, they only provide a single query function, but cannot provide further intelligent analysis functions

For further statistical and technical analysis of the found patent information, if manual operation is not only time-consuming and laborious, but also not accurate enough
