Abstract
The invention discloses a hypernym search method used for improving the keyword search efficiency. According to the method, a hypernym of a keyword is searched and matched with the keyword in published information, so that the search efficiency of the information with the full text keyword is improved through the hypernym of the keyword, and the search efficiency of information on the internet is further improved.
Description
Technical field
The present invention relates to computing machine and the communications field, particularly relate to the method for key word hypernym retrieval in information retrieval.
Background technology
In existing search technique, the semantic hypernym of the keyword in releasing news is usually used as the expanded search content of keyword, and at " a kind of method of issue, search information and device " (number of patent application: 201010507511.4), then the semantic restrictive word of hypernym as keyword is used, and using structured message label also as the one of hypernym, improve the rate of precision of information search by this method, and make structured message and unstructured information can be simultaneously searched.
But, in the present invention as stated above, in implementation step 805: after " being operated the selection of alternative hypernym by user; determine the hypernym of described search keyword ", implementation step 806 is: " mated with the issue keyword releasing news corresponding and the hypernym issuing keyword by search keyword, and mated with the hypernym issuing keyword by the hypernym of search keyword."; that is; the retrieval hypernym (no matter being the semantic hypernym of tree-shaped expression or the semantic hypernym of expressing with structured tag form) that searching system obtains all only mates the hypernym in releasing news, and does not mate the general keyword in releasing news.And although the method improves the accuracy of search information, the full property of full text information Check haves much room for improvement.
Such as: see Fig. 2,3, when obtaining keyword " Iphone4 " or " smart mobile phone " of retrieval user input, and when obtaining hypernym " manufacturer " of user's selection, the hypernym " manufacturer " obtained in the method only mates the hypernym in releasing news, and does not mate the keyword not carrying out hypernym mark.But the keyword " manufacturer " of not marking is if afterwards immediately following colon, be obviously also a kind of expression way of keyword hypernym, especially in text message.Therefore, although the method improves the accuracy of search information, the full property of Check need improve.
In order to address this problem, the present invention on aforementioned invention basis, also by the hypernym of the search keyword of acquisition with release news in general keyword and issue keyword and also mate immediately following the regular collocation of colon; To improve hypernym Information Retrieval Efficiency further.
Summary of the invention
A kind of hypernym searching method, by the hypernym of search keyword with release news in while hypernym mates, also will retrieve hypernym and the keyword in releasing news mates, to improve the recall precision of key word hypernym further.The method comprises the following steps:
Obtain the search keyword of user's input,
Participle is carried out to described search keyword,
By obtaining user to the selection operating result of alternative hypernym or automatically judge according to dependency rule, determine the hypernym of described search keyword;
The hypernym of search keyword is mated with the hypernym released news;
With or,
The hypernym of search keyword is mated with the issue keyword released news;
Extract the correspondence that the match is successful release news and show.
Wherein, the definition of hypernym is identical with " a kind of issue, the method for searching for information and device " (license number: ZL2010 1 05075111.4), and determines that the method for the hypernym of keyword is identical with foregoing invention.
Accompanying drawing explanation
Fig. 1: a kind of hypernym retrieval main flow chart
Fig. 2: user search interface schematic diagram
Fig. 3: user search interface schematic diagram
In Fig. 2, the input frame of top is search key input frame, and the word in the gridiron of below is the general alternative hypernym of structured way arrangement.
Word in " semantic hypernym node schematic diagram " on the right side of in Fig. 3 is the semantic hypernym of search key " IPhonge4 ", the optional multiple node of user.
" keyword " described in the present invention, refer to by issuing, retrieval user from primary input, through the character information of word segmentation processing.Wherein, namely word segmentation result is issue, search key.
" hypernym " that key word in the present embodiment is corresponding can be the word in any last layer after key word semanteme classification as shown in Figure 3 in tree structure, and hypernym can have the structured features as Fig. 2.
" alternative hypernym " described in the present invention, refers to the semantic hypernym of the keyword that Information issued, retrieval user can be supplied to select by application system of the present invention.Such as, the hypernym of the keyword " IBM Corporation, Apple " etc. of user's input is " manufacturer ".
Embodiment
The present invention is further illustrated below in conjunction with embodiment.
See Fig. 1, the present embodiment provides a kind of hypernym search method, and its main method flow process is as follows:
Step 101: the search keyword obtaining user's input,
Step 102: participle is carried out to described search keyword,
Step 103: to the search keyword after participle, by the corresponding relation of word and hypernym preset, determines the alternative hypernym of correspondence respectively,
Step 104: by user to the selection operation of alternative hypernym or system convention, determines the hypernym of described search keyword,
Step 105: by search keyword hypernym with release news in keyword mate,
With or,
By search keyword hypernym with release news in the regular collocation of issue keyword mate;
See Fig. 2, such as, in step 105, by obtain retrieval user select alternative hypernym " manufacturer " with release news in keyword mate with " manufacturer: " of " colon " regular collocation; It " has correlation technique to refer to " a kind of pragmatic keyword retrieval method and apparatus " (application for a patent for invention number: 201210256566.1).
Because the hypernym in text message keyword occurs with the form of keyword immediately following colon usually, therefore, by the hypernym of search keyword and release news corresponding " issuing keyword regular collocation "---keyword mates immediately following colon, can retrieve the hypernym in text message, the Check of further raising document information retrieval is complete and look into parasexuality.
Meanwhile, the keyword of semantic node hypernym matched text information that the retrieval user obtained by system is selected, compared with being match objects, also can improve the Check of information retrieval complete and look into parasexuality further with existing whole hypernym.Such as, when retrieval user is when have selected word " smart mobile phone " in any last layer after the classification of key word semanteme in tree structure after the search key " IPhone4 " inputted in keyword input frame, when not matching " IPhone4 " in releasing news, can retrieve with hypernym " smart mobile phone " keyword that releases news, call " manufacturer " relevant information of smart mobile phone.
Step 106: extract the correspondence of sending out that the match is successful and release news and show.
Such as, when the retrieval hypernym " manufacturer " of user's selection and the full text keyword " manufacturer: " in releasing news, the match is successful, and when having other Keywords matching success, then extract and issue corresponding the releasing news and show of keyword regular collocation " manufacturer: ".
