Textmining Analysis


In patent analysis, it is often useful to examine the results of patent search results from the point of view of patent applicants, patent inventors, patent classifications, etc. besides clustering by patent text mining function. It is also unusual for important information to be obtained from the distribution of patent applicants and patent inventors. Patent / integration can be seen by overlaying distributions of patent applicants and patent inventors in the distribution of each patent document.

Patent analysis by patent applicant

Click the "Applicant" tab on the "Cluster" tab of the control. Then, the patent applicant of the patent search result visualized is displayed in order from the top patent applicant. You can freely color scheme for each patent applicant.

Also, when there are a large number of applicants (for example, found from the distribution chart) it takes time and effort to find the name of the patent applicant who wishes to color. In that case, by entering the patent applicant name (partial match) you wish to search in the "search input field" located at the top of the control, you can narrow down the target patent applicant from the patent applicant listed.

Patent analysis by patent inventor

Like the patent applicant, it can also color from the viewpoint of patent inventor included in the visualized patent search result;

Compare with distribution status of various categories such as patent classification

It is possible to compare distribution charts that are colored based on clusters, patent applicants, patent inventors, etc. with distributions such as patent classifications. First, click the "Classification" tab. Then, tabs of "important word", "patent classification", and "reference number" are displayed.

Analysis of distribution of important words

The important word is the ranking display of "Related words" related to each patent document obtained by patent analysis by patent text mining function for each number. For example, if you want to know how patent documents containing related words "product" are distributed, click "product" from the list. Then, "flag" is displayed next to the patent document including the related word "product".

The analysis of important words helps you to understand roughly what kind of distribution of patent documents are distributed in each content. Because similar patent documents are likely to contain common related words. For example, in the case of this search result, you can analyze the patent group as " patent documents related to products are distributed in the upper left of this distribution chart ".

Partial match search can also be performed on important words from the list.

Distribution analysis of patent classification

As well as important words, you can flag each patent document according to the patent classification of each patent document.

Of course, you can set flags based on various hierarchies (sections, class...) of each patent classification.

At that time, I think that it is assumed that you want to know the definition of patent classification. In that case, clicking on the classification with the "cls. exp" button pressed can hierarchically display the explanation of the patent classification. By doing this, you can understand the distribution situation of patent documents with a hint on the distribution of patent classification.

Patent number (published, granted number)

For example, you may want to know where a patent document number is plotted. In that case, you can quickly find out where in the visualized patch group the flag stands by looking for patent number from the reference number tab and clicking.

You can narrow down the patent number by partial match search. For example, I narrowed it down at 428;

Advanced use of patent text mining function

You can also combine important words, patent classifications, and patent document numbers to set flags. In this case, the document that includes "strap" as related term and which belongs to FI classification section "A42B1" is flagged. This makes it possible to streamline diversified patent analysis.
