Embodiment 1

[0057] Figure 4 It is a flow chart of the patent early warning method of the present invention. The user needs to input the search formula, the file to be warned, and the warning threshold. Specifically include the following steps ( figure 1 ):

[0058] Step 1 In the data extraction stage, according to the search formula input by the user, extract and analyze in the intellectual property database and the domain knowledge base to obtain the patent special database.

[0059] Step 2 data preprocessing stage, its steps include:

[0060] Extract the title and abstract of the patent, and then perform Chinese word segmentation, part-of-speech tagging, merging synonyms, removing stop words, and word frequency statistics.

[0061] Step 3 data mining stage, its steps include:

[0062] Step 3.1 Carry out SOM self-organizing learning training on the patent vector text, and obtain the output node vector set Y. Here, we use SOM to map high-dimensional patent text data into a two-dim...

Embodiment 2

[0066] Figure 6 It is a flow chart of patent strategy coordinate analysis of the present invention. The user needs to enter a search query. Specifically include the following steps:

[0067] Steps 1, 2, and 3 are the same as in Embodiment 1.

[0068] Step 4 Result interpretation and analysis stage: analyze the strategic coordinates of patents of different subjects obtained after clustering, and send the technology strategic coordinates map to the user. In the technical strategy coordinate diagram, the centripetal degree represents the link strength between this type of patent and other types of patents, and the calculation method can be obtained by calculating the link strength between its characteristic words and other types of characteristic words. Density indicates whether the subject of this category of patents is closely related. The calculation method can be obtained by calculating the average number of times each pair of feature words appears in different documents ...

Embodiment 3

[0070] Figure 7 It is a flow chart of patent strategy coordinate analysis of the present invention. The user needs to enter a search query. Specifically include the following steps:

[0071] Steps 1, 2, and 3 are the same as in Embodiment 1.

[0072] In step 4, in the result interpretation and analysis stage, the clustered patent topics are analyzed. Each type of patent represents a different topic, and the internal similarity of the patent topics is high. Conduct technical life cycle analysis on patents with different themes, and send the obtained indicator curves and technology maturity data to users.

Abstract

The invention relates to the relevant technical field of patent information processing, in particular to a technical competition and patent early warning analysis method based on knowledge discovery. The invention provides an intelligent patent analysis method based on the knowledge discovery, and provides an analysis result with a high visual degree for a user. In brief, an intellectual property database and an industrial field knowledge library are extracted and analyzed to establish a thematic database and form a corresponding dataset. On the basis, data mining and knowledge discovery tools, including a vector space, a neural network, mathematical statistics and the like, are utilized to disclose deep information which is contained behind data, and a visual statement is provided for users. Finally, through patent early warning analysis, patent theme strategy coordinate analysis and patent theme life cycle analysis, technical competition and patent early warning are realized.

Description

technical field [0001] The present invention relates to the relevant technical field of patent information processing, specifically a technology competition and patent early warning analysis method. Background technique [0002] Today's society is in an innovative era, the Internet is becoming more and more popular, and high-tech is developing rapidly. The key to how an enterprise can keep ahead in the fierce technological competition environment is to improve the overall level of innovation of the enterprise. In a certain sense, the patent level of an enterprise represents the overall level of innovation of the enterprise. Therefore, enterprises can realize technological competition and patent early warning by analyzing existing patents. [0003] Most of the current popular technology competition and patent early warning analysis methods are manually operated, which is time-consuming and labor-intensive. The basic process is to manually set the retrieval formula, retriev...
