Fig. 3 shows the flow of the method for improving stop words search validity according to another embodiment of the invention Figure.As shown in figure 3, this method comprises the following steps:
Step S201, receives the search keyword that user provides.
Search engine server receives the search keyword that user provides in a variety of ways, for example, user is in search homepage Middle input search keyword, searched page generates the searching request for including search keyword.Searched page is by corresponding service provider There is provided, its file format is usually HTML, the page is shown in a browser, request generation code is with html language, java scripts It is included in etc. form in page source code.Searched page is handed over by browser based on the agreements such as HTTP and search engine server Mutually.
Step S202, in the search keyword for disabling retrieval user's offer in dictionary pre-established.
Step S203, judges whether to retrieve search keyword in dictionary is disabled.
Whether the step uses the method for Keywords matching to judge the search keyword of user's input for stop words.Stop words Included in storehouse and be searched the search keyword that engine server is judged as stop words.By this search keyword and stop words Keyword in storehouse matches, and if the situation that the match is successful occurs, then the search keyword by this input is judged as stopping Word, and perform step S204;If matching is unsuccessful, this search is handled as normal searching, step S205 is performed.
Dictionary is disabled typically to be provided by search service provider.Deactivation dictionary is set up to further comprise:Examine search engine index Whether the search keyword in storehouse is stop words, and the search keyword examined as stop words is included into deactivation dictionary.
First, disable dictionary can by common numeral, letter without certain sense etc. examine be stop words, such as 1,2, 130th, a, b, ze, while needing the search keyword with its meaning such as exclusion 58,110,126.
Whether it is stop words that a certain keyword can be examined according to the desirability of user.The demand of user can pass through Keyword search number of times, search result clicking rate etc. embody.For example, search engine server can record search keyword one The information such as searching request quantity, search rate in the section time, by request amount is larger and search rate is less than the pass of certain threshold value Keyword is included as stop words.The stop words of this typical type includes:First, eh, Oh, the Chinese character such as small.
Alternatively, examined according to the search result clicking rate of search keyword.Under normal circumstances, search engine service Device can at least meet the portion requirements of user to the returning result of non-stop words, therefore, and the result clicking rate of normal searching is higher. And stop words can not reflect the real intention of user, search result is seldom clicked on to user's usually not meaning.Search is drawn Holding up server can count to substantial amounts of searching request, draw the average result of each search keyword in a period of time Clicking rate, regard search keyword of the average result clicking rate under predetermined threshold value as stop words.For example, data according to statistics, The average result clicking rate of normal searching more than 1.5 times, and stop words search average result clicking rate under 0.05, then Can be some numerical value in 0-0.05 by threshold preset.
