Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, yet should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can by the scope of the present disclosure complete convey to those skilled in the art.
Fig. 2 shows the process flow diagram of the information search method based on vertical search channel according to an embodiment of the invention, as shown in Figure 2, the method starts from step S101, wherein, receives the user of client transmission at the searched key word of the first vertical search channel input.
Vertical search is also that the searched key word providing according to user is retrieved.When user uses vertical search service, at the first vertical search channel, be also that user is by inputting searched key word to be checked in the search column of the selected current vertical search channel of self-demand.Client is obtained this searched key word and is sent it to vertical search engine, and vertical search engine finds the content of this searched key word of coupling in the index database of setting up in advance.Different from universal search, vertical search is the theme with a particular category, only captures and the industry subject correlation message of paying close attention to, and according to theme feature, sets up targetedly corresponding indexed search mode, screening mode, and ways of presentation.
With universal search similarly, user can use vertical search service in many ways, for example, the vertical search channel on universal search website, in search column, button click after inputted search keyword, obtains result.Or, by the vertical website in access specific industry, field, obtain service.In above situation, normally using searched page as client-side program, by searched page, generate request, by browser, to search engine, send this request.Yet in method provided by the invention, client is not limited to searched page.For example, the vertical search of different industries service also provides the client software on multiple terminals such as operating in smart mobile phone, panel computer conventionally, and user can provide searched key word to these clients, completes generation and the transmission of searching request.
Vertical search engine receives after searched key word, and method 100 enters step S102, wherein, searched key word is carried out to semantic analysis, draws all information types of meeting consumers' demand according to the result of semantic analysis.
The searched key word that user provides is the foundation of vertical search engine judgement user information needed type.The searched key word of user's input is generally natural language, and vertical search engine cannot directly be understood the intention that searched key word comprises, and therefore, it is necessary that searched key word is carried out to semantic identification.
Particularly, due to the diversity of natural language input method, the searched key word of user's input also may be also lack of standardization, or be piling up of a plurality of keywords.Therefore, a kind of method of semantic analysis is first searched key word to be carried out to segmenting word processing, and the natural language sequence that is about to user's input is cut into significant word, and the result of then processing according to segmenting word, carries out user view identification.
In prior art, there is multiple segmenting word method, for example, the segmenting method based on string matching, the segmenting method based on understanding and the segmenting method based on statistics etc.Those skilled in the art can choose according to demand, or Integrated using several different methods.
It is basis that the result that segmenting word processes is take in intention identification, yet same segmenting word the possibility of result includes multiple intention.For example, the keyword in Fig. 1 " Liu Dehua ", although segmenting word is processed, can identify " Liu Dehua " for performing art star's name, the intention that this searched key word represents may be various, comprises picture, film, TV play, music download etc.For guaranteeing that user's request is met, the intention identification in step S102 should be considered all possible intention.
Similar with segmenting word, in prior art, also there is multiple intension recognizing method, as vocabulary coupling, statistical model, the methods such as rule parsing, those skilled in the art can according to circumstances select flexibly.
In step S102, can also further consider the demand intensity of each intention of same searched key word, for example, to searched key word " MoonlIght on the Lotus Pond ", its intention may comprise song " MoonlIght on the Lotus Pond " download, " MoonlIght on the Lotus Pond " community, and prose " MoonlIght on the Lotus Pond ".Wherein, the demand that song is downloaded may be higher, and for example 50%, and other demands are lower.
After drawing all information types of meeting consumers' demand, method 100 enters S103, wherein, judges whether the first vertical search channel provides all information types of meeting consumers' demand.
In practice, the intention power that the deterministic process in this step is described in can integrating step S102 carries out.Demand intensity to the difference intention of same searched key word quantizes, and for example, the scope of intention power is made as to 0 to 100%, and intensity level increases progressively with user's desirability.If the intention power of the information type that the first vertical search channel provides is higher than setting threshold, for example, 95%, think that this channel provides all information types of user's request; Otherwise, think that the first vertical search channel can not meet consumers' demand.
In the example shown in Fig. 1, to " Liu Dehua " this searched key word, after the intention identification of step S102, judged user substantially suitable to the intention power of the information types such as picture, film, news, music, and the first vertical search channel in Fig. 1, the picture searching channel that user selects has only returned to personage's picture, apparently, in this case, the first vertical search channel does not provide all information types of meeting consumers' demand.
And for the stronger keyword of some professionals, for example, it is the first vertical search channel that user be take the vertical search channels such as academics search, library, inputted therein searched key word " phaselocked loop ", at this moment, can think, all users' demand is all the contents such as technical documentation, paper substantially, and also the first vertical search channel can provide all information types of meeting consumers' demand.
Further, during judgement, it is also conceivable that the ageing of information, the keyword " Iphone5 " of take is example, and before listing, the intention overwhelming majority of this keyword of user search is news, and in rear a period of time of listing, user's intention is the contents such as purchase, information mostly, and after stopping production, user no longer pays close attention to the contents such as purchase, news, intention is concentrated substantially as encyclopaedia, question and answer etc., and user can be time dependent to the intention power of each information type.
Complete after above-mentioned judgement, method 100 enters step S104, wherein, if the first vertical search channel does not provide all information types of meeting consumers' demand, obtain the first Search Results of the first vertical search channel that searched key word is corresponding and the second Search Results of at least one the second vertical search channel, wherein at least one second vertical search channel provides the information type of meeting consumers' demand that the first vertical search channel unread provides.
Usually, the first user-selected vertical search channel at least can meet user's part demand, therefore, in step S104, first comprises from the search engine index storehouse of the first vertical search channel and obtains the first Search Results.
Meanwhile, in the situation that the first vertical search channel does not provide all information types of meeting consumers' demand, also need to from the index database of other vertical search channels, obtain second Search Results relevant to searched key word.Take picture searching as example, if in step S102, judged user to the demand intensity of picture a little less than, can from other vertical search channels, obtain the contents such as word, link.Fig. 3 shows the example returning results of the vertical search channel of the information search method based on vertical search channel.In Fig. 3, return results and compare with single picture, the URL link that has increased personage's concise and to the point character introduction, introduced in detail, relevant to personage and ageing stronger hot news, and the link of popular video, film etc., for user, select.
Similarly, for news search, can from the index database of other corresponding channels, obtain the information such as the picture relevant to news, video and track of issues; For map search, when certain place name of user search or mechanism, can obtain the character introduction of relevant place name, buildings picture etc.
Alternatively, for the validity of guarantee information, the second Search Results that obtains at least one the second vertical search channel that searched key word is corresponding is generally the index data base of at least one the second vertical search channel corresponding to the information type of meeting consumers' demand that provides from the first vertical search channel unread and fetches the second Search Results.That is to say, the acquisition of information outside the first vertical search channel should depend on the demand type that step S102 judges.Particularly, can be according to the intention power of analyzing in step S103, obtaining information from corresponding other channels of the information type with having certain intention power, ignores the information outside user view, the scope of search is limited within the scope of user interest, to improve system effectiveness.And for other lower information of demand intensity, can according to circumstances, suitably comprise or get rid of.
After the result of having obtained from the first vertical search channel and at least one the second vertical search channel, method 100 enters step S105, wherein, the first Search Results and described the second Search Results is integrated, and sent to client to represent.
As shown in Figure 3, the first Search Results is the personage picture relevant to searched key word " Liu Dehua ", and the second Search Results comprises profile, the news that attention rate is higher, and personage's up-to-date contents such as films and television programs of being correlated with.These results are floated and are presented at the left side of the first Search Results, even if user does not have this respect demand, also do not affect user and use.The form of integration can suitably be adjusted according to the content of the second Search Results, such as presenting with forms such as pop-up window, Framework Net Pages.
Above-mentioned integration processing further comprises according to the degree of correlation of the first Search Results and the second Search Results carries out reset according to default template to search results pages.First, second Search Results obtaining is shown after by relevancy ranking again.Here, first sequence comprises the sequence between type, is secondly the sequence of same type result.For example, in Fig. 3, preferentially having shown the profile that the degree of correlation is high in the second Search Results, is news and up-to-date video afterwards; And in results for video, only shown current two films and television programs the highest with personage's degree of correlation.
The template that reset provides in advance according to search service provider is carried out, and for example, by html language, jaVa script etc., writes in the source code of the page, and to the font size in the page, color, the embedded location of picture, video etc. etc. is set.
In the method providing in the above embodiment of the present invention, search engine is by processing the segmenting word of searched key word, intention identification waits semantic analysis, judge all information types of user's request, from the first vertical search channel, obtain the first Search Results, in the situation that the first Search Results does not provide the information type of meeting consumers' demand, from other relevant channels of the information type to user's request, obtain the second Search Results, after integrating, present.According to the method, the result obtaining combines the content of a plurality of vertical search channels, has comprised the various possible demands of user, and is not limited only to the current channel that user selects, thereby has reduced user's invalid operation, has reduced channel and has switched cost.
Fig. 4 shows the structural representation of the information retrieval device based on vertical search channel that one embodiment of the invention provides.As shown in Figure 4, this device comprises: receiver module 21, analysis module 22, judge module 23, result acquisition module 24 and integrate module 25.
The searched key word that user provides is the foundation of search engine judgement user information needed type.The searched key word of user's input is generally natural language, and search engine cannot directly be understood the intention that searched key word comprises, and therefore, it is necessary by 22 pairs of searched key words of analysis module, carrying out semantic identification.
Particularly, due to the diversity of natural language input method, the searched key word of user's input also may be also lack of standardization, or be piling up of a plurality of searched key words.Therefore, analysis module 22 generally includes segmenting word processing module 220 and intention identification module 221, wherein, segmenting word processing module 220 is suitable for first searched key word being carried out to segmenting word processing, the natural language sequence that is about to user's input is cut into significant word, intention identification module 221 is suitable for the result of processing according to segmenting word, carries out user view identification.
Segmenting word processing module 220 can utilize multiple segmenting word method of the prior art to process searched key word, for example, and the segmenting method based on string matching, the segmenting method based on understanding and the segmenting method based on statistics etc.Those skilled in the art can choose according to demand, or Integrated using several different methods.
And for the stronger keyword of some professionals, for example, it is the first vertical search channel that user be take the vertical search channels such as academics search, library, inputted therein searched key word " phaselocked loop ", at this moment, judge module 23 can think, all users' demand is all the contents such as technical documentation, paper substantially, and also the first vertical search channel can provide all information types of meeting consumers' demand.
Usually, the first user-selected vertical search channel at least can meet user's part demand, and therefore, first result acquisition module 24 will obtain the first Search Results from the search engine index storehouse of the first vertical search channel.Meanwhile, in the situation that the first vertical search channel does not provide all information types of meeting consumers' demand, result is also obtained need to obtain second Search Results relevant to searched key word from the index database of other vertical search channels.Take picture searching as example, if judge module 23 judged user to the demand intensity of picture a little less than, or other intention demands are stronger, can from corresponding other vertical search channels, obtain the contents such as word, link.Fig. 3 shows result acquisition module 24 from other vertical search channel acquisition contents an example returning results.In Fig. 3, return results and compare with single picture, the URL link that has increased personage's concise and to the point character introduction, introduced in detail, relevant to personage and ageing stronger hot news, and the link of popular video, film etc., for user, select.
Similarly, if the first vertical search channel is news search, result acquisition module 24 can obtain the information such as the picture relevant to news, video and track of issues from the index database of other vertical search channels; If map search, when certain place name of user search or mechanism, result acquisition module 24 can obtain the character introduction of relevant place name, buildings picture etc.
Alternatively, for the validity of guarantee information, the second Search Results that result acquisition module 24 obtains at least one the second vertical search channel that searched key word is corresponding is generally in the index data base of at least one the second vertical search channel corresponding to the information type of meeting consumers' demand that provides with the first vertical search channel unread and fetches the second Search Results.That is to say, the acquisition of information outside the first vertical search channel should depend on the demand type that intention identification module 221 is judged.Particularly, the intention power that can analyze according to judge module 23, obtaining information from corresponding other vertical search channels of the information type with having certain intention power, ignores the information outside user view, the scope of search is limited within the scope of user interest, to improve system effectiveness.And for the too low information of demand, can according to circumstances, suitably comprise or get rid of.
As shown in Figure 3, the first Search Results is the personage picture relevant to searched key word " Liu Dehua ", and the second Search Results comprises profile, the news that attention rate is higher, and personage's up-to-date contents such as films and television programs of being correlated with.These results are floated and are presented at the left side of the first Search Results, even if user does not have this respect demand, also do not affect user and use.Integrate module 25 can suitably be adjusted the form of integration according to the content of the second Search Results, such as presenting with forms such as pop-up window, Framework Net Pages
The template that the reset of 25 pairs of the first Search Results of integrate module and the second Search Results provides in advance according to search service provider is carried out, for example, by html language, jaVa script etc., write in the source code of the page, to the font size in the page, color, the embedded location of picture, video etc. etc. is set.
In the device providing in the above embodiment of the present invention, receiver module 21 receives the user of client transmission at the searched key word of the first vertical search channel input; 22 pairs of keywords of analysis module carry out semantic analysis, and for example the segmenting word processing module by wherein 220 and intention identification module 221 draw all information types of meeting consumers' demand; Result acquisition module 24 obtains the first Search Results from the first channel searching, and in the situation that judging the first Search Results, judge module 23 do not provide the information type of meeting consumers' demand, from other relevant channels of the information type to user's request, obtain the second Search Results, after integrate module 25 is integrated, present.The result that this device finally obtains combines the content of a plurality of vertical search channels, has comprised the various possible demands of user, and is not limited only to the current channel that user selects, thereby has reduced user's invalid operation, has reduced channel and has switched cost.
