Example Embodiment

[0034] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0035] Step 1.1, set the data source format to standard xml format, such as the following format:

[0036]

[0037] maxOccurs="unbounded">

[0038]

[0039]

[0040] type="xs:string" / >

[0041] Step 1.2, set 97 search fields as described in the summary of the invention, and process the xml data source file into a format containing these fields;

[0042] Step 1.3, set 18 optimized search fields as described in the summary of the invention, and the code information of these fields is included in the xml data source file;

[0043] Step 2. Take three servers, each with one shard as an example, import the patent into the MongoDB database cluster and set it to 3 shards;

[0044] Step 3. Also take three servers, each with one shard as an example, import patents into SolrCloud, and build indexes according t...

Abstract

The invention discloses a method for processing massive patent information and realizing optimized retrieval. The method comprises the following steps of processing patent data and setting necessary optimized retrieval fields; importing the processed patent data into a MongoDB-based database cluster and performing data storage and calling; importing the processed patent data into a SolrCloud-based full-text retrieval system and establishing a distributed index; and establishing a patent vector calculation and adjustment system combined with the optimized retrieval fields and used for sorting optimized retrieval results. According to the method, the optimized sorting of the retrieval results according to patent contents and user feedback is realized on the premise of low server resource utilization rate.

Description

technical field [0001] The invention belongs to the technical field of patent information processing, and relates to a method for optimizing patent retrieval effect by processing patent information. Background technique [0002] In the current era of rapid technological innovation and new inventions and creations, a large number of inventions and creations are submitted in the form of patent applications every day, and a large number of new patents are published and authorized every week. For individuals and organizations engaged in inventions or creations, or interested in inventions and their achievements, it is necessary to fully mine these patent information containing inventions, and to research and use their contents through retrieval and analysis. A very meaningful thing. However, because patent applications often contain a lot of relatively worthless "junk" patents, it becomes very difficult to find truly valuable patents from a large number of retrieved patent docu...
