Embodiment Construction

[0010] The present invention will be further described below in conjunction with embodiment.

[0011] A method for searching patent documents, which is used in a computer system for searching by keywords including a patent document database. The computer system is provided with a keyword category table, and the keyword category table records plural technical categories, and each technology The plural feature word corresponding to the category.

[0012] Compare the keyword entered by the user with the keyword category table, analyze the technical category the keyword belongs to, and then search the patent documents belonging to the technical category according to the keyword to find the required patent document.

[0013] Wherein, the vocabulary that is synonymous with or associated with the feature word is recorded in the keyword category table.

[0014] The characteristic words in the keyword category table respectively correspond to a specific weight value, and the computer ...

Abstract

The invention relates to a method of patent literature retrieval used for a computer system comprising a patent literature database and retrieving in keyword. The invention is characterized in that: a keyword classification table is arranged in the computer system and the keyword classification table records plural technology classifications and a plural character-word corresponding with each technology classification; keyword inputted by a user is compared with the keyword classification table and the technology classification which the keyword belongs to is analyzed, and then the needed patent literature is retrieved according to the keyword in the patent literatures belonging to the technology classification. Because adopting the method, the invention has the advantages that: when retrieving, the method firstly processes to determine for the technology classification, so as to remove a plurality of disrelated patent literatures to process to retrieve again; and retrieval efficiency is greatly improved.

Description

technical field [0001] The invention relates to the relevant technical field of patent information processing, in particular to a method for searching patent documents. Background technique [0002] In the patent document retrieval tools, there are provided "keyword" queries, but sometimes only the "keyword" query will often find the patent documents you don't need. Therefore, some official websites also provide higher-level queries. For example, in addition to inputting "keywords", users can also limit which years of patent documents are searched, or which patent applicants belong to patent documents, etc. Among them, the most important and most useful technical constraints are technical classifications, such as the most famous and widely used IPC (International Patent Classification, International Patent Classification) classification. Restricting the "International Patent Classification" is quite easy to use, but there is a problem that the "International Patent Classifi...
