Problems solved by technology

Existing sorting technologies for vertical search engines are sorted according to certain attributes of search results, such as price, time, user evaluation, etc. The sorting basis of each sorting method is relatively single-sided, and it is impossible to comprehensively sort products. Sort by value
[0008] (3) Low ease of use
The existing sorting technology for vertical search engines needs to re-select the result sorting method after the user enters the search term, which is not easy to use

Embodiment

[0030] Such as figure 1 As shown, a method for arranging industrial products vertical search engines based on utility analysis of search results is disclosed in this embodiment, Q is a search term, and D i For the i-th search result, when Q has M search results, 0≤i≤M, the vertical search engine arrangement technique includes the following steps:

[0031] Step 1: Search term Q and search result D i Participate.

[0032] The second step: the search term after the word segmentation and the search result of the segmentation service D i Carry out the result utility F calculation.

[0033]Step 3: Arrange all the search results according to the result utility F calculated in the second step, the results with high result utility F are ranked first, and the results with low result utility F are sorted at the bottom.

[0034] The pair search term Q and search result D in the first step i Word segmentation is a parallel relationship, you can pair the search term Q and the search re...

Abstract

The invention relates to a search result utility analysis-based industrial product vertical search engine arranging technology. Q is a search entry; Di is the ith search result; when Q has M search results, i is greater than or equal to 0 and less than or equal to M. The vertical search engine arranging technology comprises the following steps: segmenting the search entry Q and the search result Di; carrying out result utility F calculation on the segmented search entry and the segmented search result Di; arranging all the search results according to the result utility F, wherein the results with high result utility F are ranked close to the front and the results with low result utility F are ranked close to the back. According to the technology, the result utility is calculated and the search results are ranked according to the result utility, so that the correlation degree of the search results is greatly improved and the user experience and the ranking correctness are improved.

Description

technical field [0001] The invention belongs to the field of search engines, and in particular relates to a vertical search engine arrangement method for industrial products based on utility analysis of search results. Background technique [0002] The current search engine result ranking technology is mainly divided into two categories: one is the search result ranking technology for universal search engines; the other is for vertical search engine result ranking technology. The search result ranking technology for pervasive search engines includes web page ranking technology (PageRank technology) and word frequency-inverse text frequency technology (TF-IDF technology). [0003] PageRank technology is a search result ranking technology for universal search engines. This technology understands all web pages in the Internet and the hyperlink relationship between web pages as a "directed graph" data structure, that is: each web page is a node in the graph, and each hyperlink ...
