Construction Of A Vertical Search Engine For Patent Information

The development of the Internet has brought huge amounts of data, provides people more information. At the same time, how to accurately provide the necessary information is a problem they have to face. Traditional search engines, such as Baidu, Google, their basic functions have already meet users’ needs. When a user needs to retrieve information for a particular topic, the shortcomings, such as timeliness, low coverage, easily lead Trek, of these traditional general-purpose search engines, will be manifested. Based on the problems that exist in the general search engines, vertical search engine become the search engine development in a different direction.At first, this paper describes the overview of the vertical search engine, and the principle of the search engine, full-text retrieval technology, as well as a brief introduction to Chinese word segmentation. Then, The framework technology of Lucene.net search engine, segmentation, index and search works are introduced in this paper. This paper analyzes the design and patent-oriented vertical search engine system on the basis of in-depth understanding of search technology. The functions of the system can be divided into data import, index creation and retrieval functions. The system gets data by crawling, index and create index database by indexer, and provide users with a search function by the retrieval module. Configuration files are used during the process of indexing, so that the system has a certain degree of configurability. At the same time, multithreading mechanism are used to crawl and index the data. The efficiency of index procedure is improved."Vertical Search Engine for Patent Information" in this article is a patent-oriented vertical search engine. This system is able to provide users with professional patent search service, and users can use the system to import patent data into the database, establish patents index database, as well as patent information quick search and advanced search and so on. An effective solution to the problems existing in the general search engine for patent is completed, it can provides users with a more precise search function for patents.
