Preferably, the network equipment 2, in the time of the initial inquiry message that obtains user, can provide corresponding answer information to user.But if the answer information quantity now obtaining is more, the network equipment 2 can start the process of above-mentioned steps S2-step S6 and carry out progressively clear and definite user's inquiry demand, to reduce the quantity of answer information, provide more accurate answer information thereby can be user.

Particularly, in step S1, user submits to the network equipment 2 by its subscriber equipment 1 by inquiry message, and correspondingly, the network equipment 2 receives this inquiry message.

At this, inquiry message can give expression to user and want the content of inquiring, particularly, whether inquiry message can be for example " within 2011, Finance and Economics University Of Jiangxi is how many in acceptance cut-off point of the examinee of Jiangxi Province ", " college entrance examination 600 points above which school ", " how the Cai Nengqu U.S. studies abroad ", " applicable my women T-shirt " etc.

For example, subscriber equipment 1 can present an interactive interface to user, submits inquiry message for user in this interactive interface, and subsequently, the inquiry message of user's input is sent to the network equipment 2 by subscriber equipment 1.

Wherein, inquiry message can word or the form such as voice input.For the inquiry message of phonetic entry, subscriber equipment 1 can carry out speech recognition to it, and is converted into after word, and word inquiry message is sent to the network equipment 2; And before the word inquiry message obtaining in identification sends, subscriber equipment 1 also can point out user to confirm that whether this voice identification result is accurate.Alternately, subscriber equipment 1 also can directly be sent to the network equipment 2 by voice inquiry message, this voice inquiry message is carried out to speech recognition by the network equipment 2.

In step S2, the network equipment 2, according to user's query information, is determined the Question Classification information of the corresponding described specific application area of this inquiry message.

The corresponding specific application area of inquiry message can determine according to key to the issue information wherein, and for example, the network equipment 2 carries out cutting to inquiry message, and inquires about predetermined keywords database, to determine the corresponding application of inquiry message.At this, key to the issue information means the information that in user's inquiry message can be used for problem to be described and/or can be used for inquiry to obtain the information of definite answer, such as keyword, key sentence etc. wherein.

Alternately, carrying out based on specific application area alternately between user and the network equipment 2, for example, the interactive interface of user and the network equipment 2 is the interactive interface for specific application area, such as college entrance examination consulting interface, consultation on the study abroad interface etc.

The Question Classification information in the network equipment 2 how to confirm inquiry message particular application fields will be illustrated below.

For example, the network equipment 2 can carry out cutting to inquiry message, and inquires about predetermined keywords database, with problem identificatioin keyword from the segmenting word being obtained, and then carrys out problem identificatioin classified information according to key to the issue word.Wherein, this keywords database can be a general keywords database, can be also the keywords database for specific application area.At this, also need a Question Classification storehouse, wherein preserve the corresponding relation of key to the issue word and Question Classification information, thereby the network equipment 2 can be inquired about this Question Classification storehouse and determine the Question Classification information of inquiry message.Preferably, this Question Classification storehouse can be a word bank in the information database in respective application field.

Concrete as, the network equipment 2 carries out cutting to inquiry message " how the Cai Nengqu U.S. studies abroad ", obtain multiple segmenting words, and inquire about predetermined keywords database, to obtain key to the issue word " U.S. ", " studying abroad " from these segmenting words, thereby the network equipment 2 determines that this inquiry message is " U.S.'s consultation on the study abroad " in the Question Classification information of " consultation on the study abroad " application.

Preferably, the network equipment 2 is inquired about predetermined keywords database, obtains key to the issue word and weight thereof in segmenting word; Subsequently, the network equipment 2 can carry out problem identificatioin classified information according to the key to the issue word that wherein weight is the highest.

Concrete as, the network equipment 2 carries out cutting to inquiry message " Finance and Economics University Of Jiangxi was how many in acceptance cut-off point of the examinee of Jiangxi Province in 2011 ", obtain multiple segmenting words, and inquire about predetermined keywords database, to obtain key to the issue information from these segmenting words, as keyword " 2011 ", " Finance and Economics University Of Jiangxi ", " Jiangxi Province ", " one ", " acceptance cut-off point ", wherein the weight of keyword " acceptance cut-off point " is the highest, thereby the network equipment 2 determines that this inquiry message is " score line inquiry " in the Question Classification information of " college entrance examination consulting " application.

And for example, the network equipment 2 can carry out cutting to inquiry message, and segmenting word that interrogative is wherein adjacent merges, to obtain key sentence, and the Question Classification information of inquiring about default Question Classification template base and obtain inquiry message.Preferably, in the time that the number of words of inquiry message is less, the network equipment 2 is according to directly obtaining Question Classification information according to inquiry message inquiry Question Classification module library.Now, the network equipment 2 still needs to obtain the key to the issue word in inquiry message, for the follow-up answer information of obtaining.

Concrete as, the network equipment 2 carries out cutting to inquiry message " Finance and Economics University Of Jiangxi was how many in acceptance cut-off point of the examinee of Jiangxi Province in 2011 ", interrogative wherein " is how many " and is adjacent segmenting word " acceptance cut-off point " merging, thereby obtain key sentence " acceptance cut-off point are how many ", accordingly, the network equipment 2 is inquired about default Question Classification template base to obtain this inquiry message is " score line inquiry " in the Question Classification information of " college entrance examination consulting " application.

At this, inquiry message can be for meeting the character string of natural language custom arbitrarily; And because the network equipment 2 is not searched for according to inquiry message simply, but determine the Question Classification information of this inquiry message corresponding to specific application area, therefore, the network equipment 2 can be understood user's issue requirement better.

Preferably, the network equipment 2 can, according to the issue type information of a upper inquiry message of user's submission, be determined the Question Classification information of current inquiry message.

For example, current inquiry message is " that Beijing University? " key to the issue information is wherein " Beijing University ", and a upper inquiry message be " Tsing-Hua University OK? " the Question Classification information of a upper inquiry message is " school's brief introduction ", and the network equipment 2 can determine that the Question Classification information of current inquiry message is also " school's brief introduction ".

The network equipment 2 can, below at least under 3 kinds of situations, take this mode to determine the Question Classification information of current inquiry message:

1) when the key to the issue information in current inquiry message is not enough to determine the issue type information of current inquiry message, for current inquiry message " that Beijing University? ", key to the issue information " Beijing University " wherein fails to match Question Classification information in Question Classification storehouse.

2) dimensional information corresponding to key to the issue information of current inquiry message belongs to one of dimensional information corresponding to the key to the issue information of an inquiry message, for example, in multiple dimensional information of a upper inquiry message " Finance and Economics University Of Jiangxi was how many in acceptance cut-off point of the examinee of Jiangxi Province in 2011 " correspondence, comprise the dimensional information " time " that key to the issue information " 2011 " is corresponding, current inquiry message " 2012? " in only key to the issue information " 2012 " corresponding dimensional information " time ".

3) current inquiry message meets specific template, as " that XX? ", or " XX? " Deng.

In step S3, the network equipment 2, according to this Question Classification information, is determined corresponding other the supplementary dimensional information of this Question Classification information.

At this; for determining the corresponding answer information of inquiry message of a certain Question Classification; except existing key to the issue information in inquiry message, the network equipment 2 also needs to know the information under one or more other dimensions conventionally, supplements the corresponding problem side information of dimensional information.

For example, be the inquiry message of " score line inquiry " for Question Classification information, conventionally need the time, the specifying information of the dimension such as university's title, enrollment provinces and cities, department (literal arts or natural sciences) obtains definite answer information.

For another example, the inquiry message that is " universities and colleges are entered oneself for the examination in college entrance examination " for Question Classification information, needs the specifying information of the dimensions such as Entrance Examination, examinee location, department to obtain definite answer information conventionally.

And for example, be the inquiry message of " U.S.'s consultation on the study abroad " for Question Classification information, conventionally need the specifying information of the dimensions such as education background, TOEFL score, IELTS achievement to obtain definite answer information.

Also as, be the inquiry message of " commercial product recommending " for Question Classification information, conventionally need the specifying information of the dimensions such as trade name, sex, material, style, size to obtain definite answer information.

At this, also need a problem dimension storehouse, wherein preserve the corresponding relation of Question Classification information and dimensional information, thereby the network equipment 2 can be inquired about this problem dimension storehouse and determines the corresponding all dimensional information of a certain Question Classification information.Preferably, this problem dimension storehouse also integrates with foregoing problems class library, and also can be a word bank in the information database in respective application field.

Owing to may including the corresponding information of part dimension in the key to the issue information of inquiry message, thereby for its corresponding Question Classification information, the network equipment 2 also needs to obtain the dimensional information not comprising in this inquiry message, i.e. the corresponding supplementary dimensional information of inquiry message.

For example, key to the issue information " 2011 " the corresponding dimensional information " time " in " Finance and Economics University Of Jiangxi was how many in acceptance cut-off point of the examinee of Jiangxi Province in 2011 ", " Finance and Economics University Of Jiangxi " corresponding dimensional information " university's title ", " Jiangxi Province " corresponding dimensional information " enrollment provinces and cities ".Accordingly, the network equipment 2 comprises department in lower definite other the supplementary dimensional information of its Question Classification information " score line inquiry ".

For another example key to the issue information " 600 points " the corresponding dimensional information " Entrance Examination " in " college entrance examination 600 points above which school ".Accordingly, the network equipment 2 determines that under its Question Classification information " is entered oneself for the examination universities and colleges " other supplementary dimensional information comprise examinee location, department.

Also as, the corresponding dimensional information of key to the issue information " T-shirt " " trade name ", " Ms " corresponding dimensional information " sex " in " whether be applicable to my women T-shirt ".Accordingly, the network equipment 2 comprises material, style, size in lower definite other the supplementary dimensional information of its Question Classification information " commercial product recommending ".

In step S4, the network equipment 2 obtains and supplements the corresponding problem side information of dimensional information.

At this, problem side information is corresponding with supplementary dimensional information.For example, the problem side information corresponding with supplementary dimensional information " department " comprises literal arts or natural sciences; For another example, the problem side information corresponding with supplementary dimensional information " examinee location " includes but not limited to Beijing, Shanghai, Tianjin, Chongqing, Hebei etc.; And for example, the problem side information corresponding with supplementary dimensional information " education background " includes but not limited to master, scholar, high medium.

The mode that the network equipment 2 obtains problem side information at least comprises following 2 kinds:

1) network equipment 2 obtains problem side information by information inquiry or information processing voluntarily.

For example, in the network equipment 2, can from the user profiles of preserving in advance, obtain problem side information, particularly, in user profiles, preserve one or more user profile, such as, user's department, location, education background etc., the network equipment 2 obtains the information matching to supplementing dimensional information from these user profile.

And for example, the network equipment 2 can the IP address based on user obtains user's current location information; Or the mode that the network equipment 2 also can be located based on GPS is obtained user's current location information.The network equipment 2 can be using user's current location information as examinee location.

2) by obtaining alternately with user's one or many.

Particularly, according to predetermined group sentence rule, in order to supplement, dimensional information generation is corresponding supplements INQUIRE statement to the network equipment 2, and by one or many and user's the problem of obtaining alternately side information.

For example, the network equipment 2 can only add question mark, supplements accordingly INQUIRE statement thereby generate, such as " examination room? ", " total marks of the examination? " Deng.For another example, the network equipment 2 also can add prefix " may I ask you " and question mark, thus generate " may I ask your examination room? ", " may I ask your total marks of the examination? " etc. supplementary INQUIRE statement.

Preferably, the network equipment 2 can be according to the tone type of inquiry message, generates the corresponding INQUIRE statement that supplements.

For example, inquiry message is " parent, I am what school above? ", the supplementary INQUIRE statement that network equipment 2 generates can for " parent be may I ask how many points of total marks of the examination? "For another example, inquiry message is " Europe bar, which American university I can apply for? ", the supplementary INQUIRE statement that network equipment 2 generates can be " younger sister, how is your TOEFL score? "

The network equipment 2 can, according to the quantity of supplementing dimensional information, be determined the quantity of supplementary INQUIRE statement to be generated.For example, be each supplementary dimensional information, generate an independent supplementary INQUIRE statement; Or the network equipment 2 can, in conjunction with multiple supplementary dimensional information, generate a supplementary INQUIRE statement, such as, " parent may I ask 1) how many points of total marks of the examination? 2) where is examination room? 3) literal arts or natural sciences? "

Subsequently, the network equipment 2 will supplement INQUIRE statement and offer subscriber equipment 1; Then, subscriber equipment 1 presents supplementary INQUIRE statement on interactive interface, and receives the problem side information of user's input, is returned to the network equipment 2.

The network equipment 2 can provide supplementary INQUIRE statement to user one by one, and correspondingly, the network equipment 2 also one by one receives the problem side information that user returns, thus by repeatedly with user obtain alternately whole issue side information; Or, the network equipment 2 provides a supplementary INQUIRE statement, comprising the inquiry to multiple supplementary dimensional information, user can once or several times return to corresponding problem side information, thereby obtains alternately whole issue side information by one or many and user.

In addition, between the corresponding multiple supplementary dimensional information of some Question Classification, there is hierarchical relationship.For example, for inquiry message " how can going to the U.S.? ", its Question Classification information is " going abroad consultation ", the supplementary dimensional information of corresponding the first level of this Question Classification information is " object of going abroad ".

The problem side information corresponding with the supplementary dimensional information of this first level includes but not limited to travel, studies abroad, immigrant etc.And these problem side informations can be used for determining the supplementary dimensional information of next level, for example, and study abroad corresponding secondary supplementary dimensional information and include but not limited to education background, TOEFL score etc.

Therefore, the supplementary dimensional information that the network equipment 2 can be the first level according to predetermined group sentence rule generates corresponding supplementary INQUIRE statement, and generated supplementary INQUIRE statement is offered to subscriber equipment 1; Subscriber equipment 1 presents this supplementary INQUIRE statement to user on interactive interface, and receives the problem side information of user's input, sends it to the network equipment 2.

Then, the network equipment 2 is determined the supplementary dimensional information of next level according to the problem side information of user feedback, and generate the supplementary INQUIRE statement corresponding with it and offer user, until the network equipment 2 obtains all supplementary corresponding problem side informations of dimensional information.

At this, for the purpose of simple declaration, only give an example with two-layer hierarchical relationship, those skilled in the art will be understood that also can has three layers of even more hierarchical relationship between multiple supplementary dimensional information.For example, the supplementary dimensional information of the first level is the object of going abroad, the supplementary dimensional information of the second level is immigrant's kind, and problem side information includes but not limited to skill immigration or migration, investor etc. accordingly, and these problem side informations can be used for determining the supplementary dimensional information of the 3rd level.

In step S5, the network equipment 2, according to inquiry message and problem side information, is determined corresponding answer information.

At this, answer information is available to the information of user for response inquiry message.

The network equipment 2 determines that the mode of corresponding answer information includes but not limited to following 2 kinds:

1) information database of inquiring about pre-established specific application area is determined corresponding answer information.

At this, specific application area include but not limited to take an examination consulting, going abroad consultation, commodity purchasing consulting etc.

In internet, exist a large amount of source datas, belong to examination consulting field such as the source data in the websites such as, Sohu's college entrance examination, Sina's college entrance examination, Chinese education be online; Source data in the websites such as Baidu's education, golden Gillette consultation on the study abroad, New Orient service for studying abroad belongs to consultation on the study abroad field.

The network equipment 2 can gather a large amount of source datas that belongs to some specific application area from multiple websites, and then, the network equipment 2 extracts the corresponding structural data of each dimensional information from source data, to set up the information database of this specific application area.

For example, in source data, comprise the content relevant with acceptance cut-off point, and acceptance cut-off point are to be determined by time, university's title, enrollment provinces and cities, department (literal arts or natural sciences), enrollment batch these 5 dimensional information, for example, shown in following table one:

Table one

The network equipment 2 can extract as the corresponding structural data of each dimensional information in table one, and from other source datas, extracts equally in this way the relevant corresponding structural data of dimensional information of each college entrance examination, to set up accordingly the information database of college entrance examination consulting.

Those skilled in the art will be understood that; the process of establishing of the information database of above-mentioned score line is only for giving an example; and should not be regarded as any limitation of the invention; the process of establishing of the information database of any other existing or specific application area in the future; as applicable to the present invention; within should being included in scope of patent protection of the present invention equally, and be contained in this at this with way of reference.

After the information database of specific application area is set up, the network equipment 2 can be determined corresponding answer information by the information database of inquiry specific application area.

For example, for inquiry message " within 2011, Finance and Economics University Of Jiangxi is in acceptance cut-off point of the examinee of Jiangxi Province ", the network equipment 2 determines that the key to the issue information of this inquiry message is " 2011 ", " Finance and Economics University Of Jiangxi ", " Jiangxi Province ", " a collection of ", " acceptance cut-off point ", and the problem side information of obtaining this inquiry message is " natural sciences ", therefore, the network equipment 2 is inquired about the information database of college entrance examination consulting, can obtain answer information " 555 points ".

Except the above-mentioned only inquiry mode using key to the issue information and problem side information as querying condition, the network equipment 2 also can be inquired about in conjunction with dimensional information, for example, using " time=2011 year ", " title=Finance and Economics University Of Jiangxi of university ", " enrollment provinces and cities=Jiangxi Province ", " enrollment batch=a collection of ", " inquiry of problem types=score line ", " department=natural sciences " as querying condition, inquire about the information database of score line, to obtain answer information.

2) for the inquiry message with prediction character, determine corresponding answer information in conjunction with current concern temperature.

For " college entrance examination in this year 600 points above which school ", " this year, which American School master's graduation can apply for " this class contains the inquiry message of predicting character, the network equipment 2 can not directly obtain corresponding answer information by Query Information database, but the network equipment 2 can be according to the historical data in information database, and in conjunction with the current concern temperature of this application, determine corresponding answer information.

Wherein, current concern temperature is that network operation daily record based on to nearly a period of time of a large number of users is carried out statistics and analysis and determined.For example, by recording and add up nearly three months information relevant with Tsing-Hua University that share of a large number of users in forum of Baidu, learn about the click of Tsing-Hua University, the operation amount of browsing, put question to, answering, thereby determine the current concern temperature to Tsing-Hua University, current concern temperature for example can embody by the form of weighted value, and weighted value is greater than 1, illustrates that current concern temperature is high, weighted value is less than 1, illustrates that current concern temperature is low.

Therefore, for " college entrance examination in this year 600 points above which school " this inquiry message, its key to the issue information is " this year ", " 600 points ", problem side information comprises " Beijing ", " natural sciences ", " a collection of ", the network equipment 2 can be recruited over the years according to each university first batch of natural sciences examinee's college entrance examination acceptance cut-off point in Beijing, carry a grade line, admission best result over the years, average mark, and in conjunction with the current concern temperature of each university, predict that each university recruits first batch of natural sciences examinee's college entrance examination acceptance cut-off point this year in Beijing, for example, calculate a certain university recruits first batch of natural sciences examinee's college entrance examination acceptance cut-off point over the years mean value in Beijing, and this mean value and the weighted value that embodies current concern temperature are carried out to multiplying, the result of this multiplying is recruited to first batch of natural sciences examinee this year as this university college entrance examination acceptance cut-off point in Beijing, subsequently, the network equipment 2 can select the wherein university name of acceptance cut-off point below 600 points to be referred to as answer information.

Preferably, in answer information, also can comprise answer summary info.

Wherein, answer summary info generates according to answer information, to summarize content, the statistical information etc. of answer information.

For example, for inquiry message " 600 points of which universities above? " the definite answer information of the network equipment 2 comprises " China University of Political Science & Law, Beijing Jiaotong University, Beijing Language and Culture University, University of Science & Technology, Beijing ... ", in this answer information, comprise 37 universities, therefore, the network equipment 2 can generate answer summary info " have 37 universities, wherein each university at least comprises 2 optional specialties ".

Preferably, the network equipment 2 also can, according to the corresponding relevant dimensional information of answer information, provide the answer information of again obtaining based on relevant dimensional information to user.

Wherein, answer information is generally to there being relevant dimensional information, for example, for inquiry message " 600 points of which universities above? " the definite answer information of the network equipment 2 comprises " China University of Political Science & Law's (science of law, journalism), Beijing Jiaotong University's (civil engineering work, biomedical engineering), Beijing Language and Culture University's (translation, English), University of Science & Technology, Beijing's (applied physics, Mathematics and Applied Mathematics) ... ", this answer information is each university's title (major name), and the relevant dimensional information corresponding to this answer information can be major name, therefore, the network equipment 2 also can obtain corresponding new answer information by the major name based on wherein relevant, as " civil engineering work (University of Science & Technology, Beijing, Beijing Jiaotong University), journalism (China University of Political Science & Law, Beijing Language and Culture University) ...
