Method and apparatus for quickly searching for contents required to be queried

Abstract

The invention discloses a method and an apparatus for quickly searching for contents required to be queried. The method comprises the steps of acquiring various data from the internet, and performing associated storage on the data and corresponding nodes in a graphic structure in a graphic database; converting non-structured data into structured data capable of analyzing applications; performing cleaning and building a unified data model; establishing a data warehouse by adopting an HBase, and loading the cleaned data into the data warehouse; associating dispersed data through company names, abbreviations or stock codes, and storing the dispersed data in the corresponding nodes according to modes of nodes and relationships in the graphic structure; extracting the data stored in each node from the graphic structure, and establishing a Chinese index; and inputting a statement required to be queried, searching for related graphic structures by adopting a traversal algorithm, and arranging the searched graphic structures according to correlation values. According to the method and the apparatus, the retrieval can be quickly carried out; the query is efficient and accurate; relatively good experience can be provided for users; and the matching efficiency is relatively high.

Description

technical field [0001] The invention relates to the field of search engines, in particular to a method and device for quickly searching for content to be queried. Background technique [0002] Search engines rely on web crawlers to effectively collect relevant web page information from the massive Internet data. How to improve the search efficiency of web crawlers is a research hotspot in this field. A traditional web crawler includes a protocol processing module. URL (uniform resource locator, also known as webpage address, is the address of a standard resource on the Internet) consists of two parts: a protocol module and a detection module. Among them, the protocol module is used to provide the network protocol required by the web crawler to solve how to obtain web pages; the detection module is responsible for sorting the collected URL information and processing duplicate content on the network to improve the search efficiency of the web crawler.

Problems solved by technology

[0003] However, general crawler search has the following shortcomings: because the goal of crawling is to cover as large a network as possible, the results of crawling will inevitably contain a large number of web pages that users do not need; For data with a certain structure, general search engines are mostly based on keyword retrieval, and it is difficult to realize the requirements for querying semantic information and intelligent indexing engines
