Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail.
Below in conjunction with Figure of description, embodiments of the invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.And in not afoul situation, the feature in embodiments of the invention can be combined with each other.
Embodiments of the invention provide a kind of intelligent answer robot of personalization, particularly a kind of two-way question answering system of personalization meeting user characteristics, intelligent sound assistant, chat robots, the automatically intelligent service system such as customer service and expert system can be widely used in, initiatively can put question to user, or initiatively initiate some topics to user.Wherein, the personality preference of the problem proposed to user or topic and the user of initiation, age, sex and occupation etc. are relevant, and these problems are more mated with user characteristics.Thus the behavioural habits of user are analysed in depth by the two-way interactive of user and question and answer robot, and will react on the analysis result of user initiatively in question mechanism, form the degree of intelligence that benign cycle improves system.
Before carrying out active enquirement, needing to build the domain model for carrying out semantic parsing and/or semantic classification model, identifying the input information representation user view out of user.In a preferred example, intention assessment engine judges by domain model the intention that user is possible.Draw above-mentioned domain model by training every field data separately, it is a kind of classification model in essence, utilizes semantic subsumption algorithm the order that user inputs can be referred to different fields.As user's input " Spicy diced chicken with peanuts ", judge that user view may follow restaurant, menu and encyclopaedia to have relation by semantic subsumption algorithm.Described semantic subsumption algorithm is a Semantic Similarity Measurement mode by using the modes such as regular expression, syntactic analysis, grammatical analysis or keyword resolution to realize, and its data basis is then a large number of users, the FIELD Data of training domain model.
Before carrying out active enquirement, also need to build user information database and store the customer parameter relevant to the sex of user, age, occupation, hobby and trip mode etc.This user information database is the mutual topic in order to identify user in follow-up active question process.Such as, user profile comprises age, sex, birthday, hobby, constellation and local etc., also comprises between occupation, travel modal, WA, taste of diet and frequent activity venue etc.
Such as, the information of party A-subscriber is " 8 years old, man, October 1 birthday, Beijing, local ".If the question information that intelligent robot receives party A-subscriber's input is " where you are ", then system judges that mutual topic can be relevant to customer parameter " local ", namely using " Beijing, local " this information of party A-subscriber as reference information.The problem of the active question that system goes out has " I is Pekinese, and you are also Pekinese ", or " I is Shanghai people, and you are Pekinese "
System initiatively can also initiate topic within user's long-time sluggish time period.For the information of above-mentioned party A-subscriber, the topic that system is initiatively initiated is such as " place which Beijing has joyful " or " Safari Park, Beijing is joyful " etc.
Below in conjunction with specific embodiment, two-way question and answer data processing method and system are described in detail.
embodiment one
Fig. 1 is the flow chart of steps of two-way question and answer implementation method.
In step S101, build domain model as described above and/or semantic classification model.
In step s 102, the user information database storing user profile is built.This user information database stores initial customer parameter, and can carry out improving and upgrading to user information database in follow-up question answering process.
In step s 103, obtain user's question information and carry out intention assessment.
Specifically, first gather the command information of user's input, then command information is converted to normative text format information, and pre-service is carried out to text formatting information, thus obtain question information to be identified.Wherein, the command information of user's input can be at least one in phonetic order, text instruction or positioning instruction.
Pretreatment operation can comprise denoising, intelligent correction, word segmentation processing and named entity recognition etc.Wherein, denoising mainly filters out the insignificant words such as invalid word, stop-word, does not affect the intention of user's input after filtration; Correction process is, according to phonetic error correction, mode such as statistics error correction, semantic error correction etc., correction process is carried out in the input of user's erroneous input or speech recognition errors, draws relatively accurate input; Word segmentation processing and named entity recognition carry out participle by modes such as Hidden Markov Model (HMM) to user's input, and mark each part of speech, also marks accordingly for named entity simultaneously.
Such as user's input " going to Xizhimen how to walk ", then " go " and noun " Xizhimen " by obtaining taxis verb after participle, the named entity simultaneously obtaining " Xizhimen " is place name, and " how walking " represents that user's is intended that inquiry route.
In this step, semanteme parsing can be carried out based on the domain model built in advance and/or semantic classification model to input information and identify user view.If the input information of user is clear and definite asked questions, such as " today, weather how " " goes to Xizhimen how to walk " etc., then directly can recognize the intention of user from problem.
In addition, the sight conjunctive word in user's question information can also first be extracted, according to the context identification dialogue scenarios of described sight conjunctive word and current session.Carry out semanteme according to domain model to described question information again to resolve, in described dialogue scenarios, carry out intention assessment.Wherein, dialogue scenarios represents User Status and user's request etc., for accurately judging that user view is replied accurately to provide in follow-up answer process.In this course, mainly rely on the descriptor extracted in the context of current session and decide, the judging to resolve as semanteme of sight provide effective support, improves greatly semantic accuracy rate of resolving.
Such as, the information of party B-subscriber is " man, Shanghai, local, bank clerk, trip of driving ".And in the dialogue of party B-subscriber and robot system, once there is information such as " road of today blocks up very much, late again " " getting on the bus seldom in road ".If the question information of party B-subscriber is " going to Xizhimen how to walk ", then determine that " Xizhimen " is for sight conjunctive word, system identification is that party B-subscriber will drive to go to Xizhimen to current dialogue scenarios, recognizes being intended to " obtaining the jam situation of current location to Xizhimen " of party B-subscriber in this dialogue scenarios.
In step S104, generate the first response result corresponding to question information according to user view.Such as, the question information for user " goes to Xizhimen how to walk ", if system recognize user in step s 103 be intended that inquiry driving route, then the first response result provided is " drive route of the shortest path from current location to Xizhimen "; Or recognize being intended to " obtaining the jam situation of current location to Xizhimen " of user in step s 103, then the first response result provided is " obtain the jam situation of current location to Xizhimen, and provide rational bypass route ".
In step S105, question information is mated with the customer parameter stored in user information database, when the two forms association, perform following step S106, enter flow process of initiatively asking a question.If the two can not form association, be then back to step S103.
Such as, the information of above-mentioned party A-subscriber is " 8 years old, man, October 1 birthday, Beijing, local ", then customer parameter is " age ", " sex ", " birthday " or " local ".If the question information that system acceptance inputs to party A-subscriber is " near have what dining room ", then recognize being intended in " dining room of finding nearby " of user, now user view and customer parameter do not form and associate, and directly export the first response result to user view.Such as, the first response result of output is " 500 meters have Malus spectabilis dining room eastwards ".
If the question information that system receives party A-subscriber's input is " you this year how old ", then user view forms with customer parameter " age " and associates, and triggering is initiatively asked a question mechanism.In subsequent step, system is to providing the first response result, and generates the problem " I 5 years old this year, you have 8 years old " of question.
In step s 106, initiatively the ask a question problem corresponding with question information is generated according to the session rules preset.Described in last example, if the question information that system receives party A-subscriber's input is " you this year how old ", then the problem generating initiatively question is " you have 8 years old ".In step s 107, described first response result and described problem of initiatively asking a question is exported.
Fig. 2 is a preferred example of process of initiatively asking a question.System can calculate the problem of multiple possible active enquirement according to the question information of user.System also can offering question storehouse, for storing all problems that may put question to.The session rules preset can be the maximum matched rule initiatively between asked questions and customer parameter.
In fig. 2, extract at least one to be selected problem corresponding with question information first in step s 201, then, in step S202, calculate the matching degree of at least one problem to be selected described and customer parameter.Next, in step S203, select the problem the highest with customer parameter matching degree as problem of initiatively asking a question; And, when the matching degree calculated is too low, it fails to match to be then judged as at least one problem to be selected described and customer parameter, generates the problem of initiatively asking a question adapted to customer parameter in step S204, makes the problem of initiatively asking a question generated more meet user characteristics.
Such as, C user is the little girl of 6 years old, if system acceptance to C user put question to as " we play games OK together ", and in user information database, do not match the hobby of C user, then design the problem more meeting little girl's feature, system initiatively question is " good, to come together how to play Barbie doll ".
Such as, D user is 50 years old, if the D user that system receives puts question to as " having the game what is joyful ", and in user information database, does not match the hobby of D user, then designing the problem of initiatively puing question to is " how carrying out fighting landlord ".
In addition, if the problem to be selected calculating the highest corresponding matching degree in the result of acquisition in step S202 is not unique, then in step S203, carry out Stochastic choice, namely from the problem multiple to be selected of correspondence the highest matching degree Stochastic choice problem as problem of initiatively asking a question.
Such as, the information of above-mentioned party B-subscriber is " man, Shanghai, local, bank clerk, trip of driving, hobby music and outdoor exercises ".If system receives the enquirement of party B-subscriber for " it is movable what weekend has ", the problem to be selected then calculating the highest matching degree in step S202 has two, be " weekend goes to hear a concert " or " weekend goes to drift about " respectively, in step S203, Stochastic choice one exports as the problem of initiatively asking a question subsequently.This design considers in current user information database to determine most suitable problem of initiatively asking a question, and needs again to put question to get more, more detailed user profile to user.Therefore, Stochastic choice problem exports.
As can be seen from above-mentioned analysis, according to the two-way question and answer data processing method that the present embodiment provides, intelligent robot not only can answer user the problem proposed, and can also design the problem that conforms to user characteristics and put question to user, makes interested to interactive process of user.
embodiment two
Fig. 3 is the flow chart of steps of the two-way question and answer data processing method that the present embodiment provides.With embodiment one unlike, user can also feed back in two-way question answering system to the answer of problem of initiatively asking a question, on the one hand user information database is carried out supplementary and perfect, also intelligent training is carried out to system on the other hand, make system in question answering process subsequently, design the problem of feature of being more close to the users.
In figure 3, the identical symbol logo of the step identical with embodiment one, be mainly described in detail to the feedback procedure of the present embodiment and the training process of flow process of initiatively asking a question at this, other guide repeats no more.
In step S108, receive second response result of user for described problem feedback of initiatively asking a question.For above-mentioned party B-subscriber, if party B-subscriber puts question to " you how old " to intelligent robot, robot answers and initiatively puts question to " I have five years old, you ".Party B-subscriber is " I have 30 years old " to " you " this second response result that initiatively asked questions feeds back.
In step S109, in the second response result, extract the related information of customer parameter, and upgrade the customer parameter of user information database according to related information.That is, intelligent robot extracts the information associated by customer parameter " age " in the second response result is " 30 years old ".Then the user information database of party B-subscriber is upgraded, add " age is 30 years old " this information.
In step s 110, according to the second response result, flow process of initiatively asking a question is trained, mate with the customer parameter after making the problem of initiatively asking a question of generation and upgrading.Get back to step S105 and step S106 afterwards, generate the problem of initiatively question.Specifically, the process of training flow process of initiatively asking a question comprises the renewal of matching process and the renewal of dialogue criterion.Be embodied in after with the addition of new customer parameter in user information database or being revised as new customer parameter, the customer parameter after needing according to renewal mates, and determines whether there is association; Correspondingly, in subsequent step according to dialogue criterion select with upgrade after the highest problem of customer parameter matching degree.Like this, by carrying out intelligent training to system, make system in question answering process subsequently, design the problem of feature of being more close to the users.
Such as, if party B-subscriber puts question to " having good-looking film recently " in dialogue next time, it is calculate matching degree according to the parameter " 30 years old age " of question information and party B-subscriber and " sex is the male sex " that robot upgrades session rules, the first response result generated is " " trump secret service " is hunky-dory ", and the problem of the active question of generation is " you like seeing action movie ".
embodiment three
Fig. 4 is the flow chart of steps of the two-way chat data disposal route that the present embodiment provides.Compared with above two embodiments, the method for the present embodiment can not only realize nan-machine interrogation, can also initiate the chat topic meeting user characteristics, can promote the experience of user, possess stronger practicality in the chat process of class of talking in professional jargon.
Fig. 4 is the improvement made on the basis of Fig. 3, and the step identical with Fig. 3 repeats no more.
After step s 102, the chat message that step S111 receives user is performed.Subsequently, according to the customer parameter design chat scenario upgraded in user information database in step S112, and in step S113, under chat scenario, the dialogue of talking in professional jargon meeting customer parameter is generated.Perform the answer that step S108 receives user again.
Such as, first party B-subscriber initiates to chat " playing games; It rs boring really " everyday, robot is according to the parameter upgraded in party B-subscriber's information " 30 years old age ", design the scene of chat for " user is on furlough ", generate the conversation message of class of talking in professional jargon for " 30 years old also play games, not promising " everyday.
It should be noted that, these two processes that active is asked a question and initiation is chatted complement each other and promote.Initiatively the interaction point of question is more, more can form the customer parameter reacting user characteristics in more detail, thus in chat process, initiate user interested or meet the topic of user's application demand, forms more well interaction with user.
