Problems solved by technology

However, the search grammars supported by these websites are quite different, so that users must pay attention to different search rules when searching patent information websites in different countries, which consumes manpower and reduces efficiency.
In the traditional search program design, there is no unified grammar description method; in the grammar analysis, the search string is matched word by word, and its grammar rules are embedded in the code; Java code is written manually; and the grammar maintenance is difficult and the logic is complicated

Embodiment Construction

[0012] like figure 1 Shown is a system architecture diagram for implementing the syntax conversion method for patent information retrieval of the present invention, which includes a plurality of client computers 1, at least one server 2, at least one database 3 and a network 4 connecting them. The user enters a search string through the client computer 1 and sends it to the server 2. The server 2 performs grammatical analysis on the search string, quickly searches the relevant patent information from the database 3, and sends the search results to the user after processing. terminal computer 1; if there is no relevant patent information in the database 3, the server 2 can automatically perform grammar conversion on the input search word string, that is, translate the grammar into the search grammar of the corresponding national patent website, and conduct the search through the network 4 to the patent website of the corresponding country. Search and get search results.

Abstract

Disclosed is a grammar conversion method for patent information indexing which can automatically convert indexing grammar into different indexing grammars of each patent information website of different countries. The method comprises following steps of: inputting indexing string; performing grammar analysis on entered indexing string; generating grammar tree after cutting indexing string automatically; optimizing the grammar tree; performing meaning analysis and type checking on optimized unit; converting grammar by translating the analyzed grammar into different indexing sentences via loading different Schema languages; generating sentences adapting for network database indexing grammars of each country patent bureau, also, generating SQL indexing sentences and XML or other forms indexing sentences.

Description

【Technical field】 [0001] The invention relates to an information retrieval method, in particular to a syntax conversion method for patent information retrieval. 【Background technique】 [0002] Patent information refers to the collection of information including patent application, authorization, patent legal status, patent technical content, etc. knowledge base. Patent information is of great significance to technological progress and scientific research and development. Therefore, if you are an inventor, you should know what you know and know the development process of the technology you have mastered; if you are an entrepreneur, you should monitor competitors’ new products and patents obtained by competitors; if you are engaged in applied research, you must Pay attention to new patents and patents under review in related fields from time to time to grasp the development trend of key technologies. Patent search can help R&D personnel and enterprises to track technologica...
