Embodiment Construction

[0037] Since the existing data search technology searches based on the text content such as the word frequency and position of the participle words of the search keyword, this kind of search often ignores the search demand information and obtains wrong search results. Generally, the data search method considering the search demand needs to first count the demand probabilities of the search keywords and their participle words in the search log, and establish a demand probability model. When searching according to the search keywords, the search requirements of the search keywords and their participle words are determined according to the probability model. Then it is necessary to calculate the correlation between various requirements and the search page to obtain the correlation between the requirements of the search keyword and the searched pages, and display the searched pages according to the correlation. However, this search method needs to establish a probability model bas...

Abstract

The invention provides a data search device and a method thereof. The device comprises a segmentation module, a score obtaining module, a matching calculation module and a search ordering module, wherein the segmentation module is used for performing segmentation on received search keywords to obtain segmented words of the search keywords; the score obtaining module is used for obtaining the field score of the segmented word of at least one search keyword and calculating the field score of the search keyword according to the field score of at least one segmented word; the matching calculation module is used for calculating the field scores of the search keywords respectively and searching the matching degree of the field scores of all documents searched according to the search keywords; the search ordering module is used for ordering the documents searched according to the search keywords based on the matching degree. According to the method and the device, a search result which meets the search requirement better can be provided according to the search keyword.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a device and method for data search. Background technique [0002] With the development of Internet technology, the amount of network information data is also increasing, such as a large amount of video information in video websites, information released by a large number of users in website forums, and massive historical logs of users. In order to achieve a certain operational purpose, it is necessary to obtain data that meets the demand from a large amount of network information. [0003] Existing data search technologies mostly use search based on search keywords (queries), and the search engine server feeds back pages matching the search keywords including search results according to the input search keywords. And, sorting is performed in the search results, and the pages most relevant to the search keywords are ranked at the top. [0004] However, existing data search...
