Method and device for sequencing search results

Abstract

The invention relates to the field of internet information treatment and discloses a method and a device for sequencing search results. The method comprises the following steps of: acquiring corresponding search results and preset field attributions corresponding to the search results according to search keywords input by a user; calculating the field attribution of the search keywords according to the field attribution of each search result; respectively regulating the correlation of each search result with the search keywords and the authority of each search result according to the field attribution of each search result and the field attribution of the search keywords; and sequencing the search results according to the correlation and authority of each search result after regulation. Therefore, the sequencing accuracy of the search results are improved at the aspects of the correlation and the authority, the search quality is effectively improved, and the system performance is promoted.

Description

technical field [0001] The invention relates to the field of Internet information processing, in particular to a method and device for sorting retrieval results. Background technique [0002] With the development of Internet technology, the scope of application of search engine technology is becoming more and more extensive. When traditional search engines respond to users' retrieval needs, they mainly sort the retrieval results according to the following two parameters: one is the retrieval results (also known as url, uniform resource location), and the correlation between the search keywords (also known as query) input by the user, and the second is the authority of the url itself. The so-called authority can be based on the PageRank (page level) of the url or the url's It is determined by the SiteRank (site level) of the site. Generally speaking, the URL with higher relevance to the query ranks higher. In the case of similar correlation, the URL with higher authority rank...

Problems solved by technology

[0004] 1. Due to the short length of the query, it is difficult to perform semantic analysis on it, so the calculation of relevance generally depends on literal matching. There is also a literal match between url and query, and there will also be escapes, so that it is actually irrelevant For example, the query is "Mopan", and the subject of the url is "Mopanshan". The two are not related, but because of the literal match, the url with the subject "Mopanshan" also becomes the search result , if the url still has a higher PageRank at this time, it will make the url have a higher ranking, thereby affecting the correct ranking of other urls;

[0005] 2. At present, there is a common situation on the domestic Internet: Hackers use various technical means to attack authoritative sites such as governments and companies, and then inject low-quality pages in the fields of online games, gaming, and medical treatment under these sites. Inherit the SiteRank of the site where it is located, so it has a higher level of authority. When users enter queries in fields such as online games, gaming, and medical care, the rankings of these inferior pages are similar to or even higher than those of real authoritative sites in this field. , thus affecting the correct ranking of other urls;

[0006] 3. Some comprehensive super sites cover a very broad field and have a very high SiteRank. In fact, these super sites are not as authoritative as some specialized sites in certain fields, but because of these super sites The website has a higher SiteRank, so that the urls belonging to these super websites are more authoritative in the fields covered by the super websites than those specialized authoritative sites in the corresponding fields, and get an unfairly high ranking, which in turn affects other urls correct ranking of
