In the embodiment of the present invention, in the time releasing news, be that corresponding hypernym determined in the issue keyword releasing news, not only searched key word is mated with releasing news and issue keyword in when search, also by searched key word with issue the hypernym of keyword and mate, there is no the issue keyword that the match is successful or the information searching that causes of releasing news is not accurate enough and search the problems such as more irrelevant information to solve.
In the present embodiment, issuing keyword and searched key word can be one or more words, can be also in short or title, passage etc.
Hypernym corresponding to key word in the present embodiment can be the word in the semantic any last layer sorted out in rear tree structure of key word.For example, spanner, pliers can classify as jack board, and jack board can classify as instrument, and hypernym can have the structured features as Figure 1A.
Referring to Figure 1B, the main method flow process releasing news in the present embodiment is as follows:
Step 101: carry out the information that information issue acquisition are issued.
Step 102: obtain the issue keyword that releases news corresponding.Concrete, can obtain the issue keyword that releases news corresponding by user's input operation.Or, carry out participle to releasing news, obtain by the word obtaining after participle the issue keyword that releases news corresponding.
Step 103: the hypernym of determining described issue keyword.
Because step 102 and 103 has multiple specific implementation, introduce in detail below by two exemplary embodiments.
Referring to Fig. 2, the method flow releasing news while determining hypernym in the present embodiment is as follows:
Step 201: carry out the information that information issue acquisition are issued.
Step 202: carry out participle to releasing news, obtain by the word obtaining after participle the issue keyword that releases news corresponding.Preferably, carry out participle in this step to releasing news, the filtering word that has nothing to do, as the pronoun such as " ", " I ", auxiliary word and conjunction.Using remaining sincere word (as title, verb etc.) as issuing keyword.
Step 203: to the each issue keyword after participle, by default word and the corresponding relation of hypernym, determine respectively corresponding hypernym.For example, the hypernym of the word of the date such as year, month, day, minute, second time class is the time; The hypernym of the words such as province, city, street, shop, center is place; The hypernym of the word such as shirt, trousers is clothes.Do not enumerate, the corresponding relation of word and hypernym can be realized by database herein.As shown in Figure 3A, left side is to release news to example, and the hypernym corresponding with the title that releases news (being also to issue keyword) classified on right side first as.Or for example Fig. 3 B, adds concordance list by hypernym, after each issue keyword, increase corresponding hypernym, as the word in bracket.
For example, the information of issuing is the video of NBA Basketball Match, issuing keyword (or title) is the video of the NBA of XXX team Basketball Match on September 30, system carries out finding that there is the moon and day after participle and identification to keyword, generate or Automatically invoked hypernym " time ", identify " match " in Basketball Match, can generate or Automatically invoked hypernym " behavior ".
In step 203, also can export hypernym input frame to user, input hypernym by user.Or preferably, input alternative hypernym to user, this alternative hypernym can be provided by system, or, keyword is carried out providing after participle and identification, also can obtain hypernym according to the hypernym of user's Freely input, shown in Fig. 3 C, by user, the selection of alternative hypernym is operated to (as clicking operation), determine the hypernym of described issue keyword.
Referring to Fig. 4, the method flow releasing news by content structure in the present embodiment is as follows:
Step 401: carry out the information that information issue acquisition are issued.
Step 402: the issue keyword that releases news corresponding that obtains user's input by content structure.
