Method and device for measuring performance of search engines

Abstract

The invention provides a method and a device for measuring the performance of search engines. The method includes rating the correlation of at least one query result item obtained by at least one piece of Query by means of querying the to-be-measured search engines so as to obtain the first theoretical maximum score values of home page query results obtained by the various pieces of Query from the to-be-measured search engines; determining second theoretical maximum score values of the home page query results obtained by the various pieces of Query from the to-be-measured search engines according to rated values of the correlation of query result items obtained by the various pieces of Query from at least one reference search engine; measuring the performance of the to-be-measured search engines according to the first theoretical maximum score values and the second theoretical maximum score values. The method and the device in an embodiment of the invention have the advantages that in-depth and refined measurement results can be provided by the method and the device, and accordingly follow-up search engine optimization work can be effectively guided.

Description

technical field [0001] The invention relates to the technical field of information search, in particular to a method and device for measuring search engine performance. Background technique [0002] With the continuous development of Internet technology and the continuous expansion of information, people's demand for network information is getting higher and higher, and search engines have become an important tool for people to obtain network information. After the user inputs a query Query (search), the search engine usually returns the page containing the query Query to the user as a query result. [0003] In related technologies, when evaluating the relevance of a search engine, it is generally to obtain the first N query result items of each query Query, score them respectively, and perform evaluation according to the scoring situation. However, there may be many reasons why the query does not get a full score. For example, the query itself has no resources, such as "XX...

Problems solved by technology

However, there may be many reasons why the query does not get a full score. For example, the query itself has no resources, such as "XXXsdfdsf123", which is obviously meaningless, and there may be no relevant resources; All valid data is collected; another example is that the valid data collected by this query is not sorted, etc.

It can be seen that the current evaluation scheme cannot distinguish the above reasons, so it is urgent to provide a solution to this technical problem
