Specific embodiment
The implementation of present disclosure is more fully described below with reference to accompanying drawings.Although showing the disclosure in attached drawing Certain implementations of content, it should be understood that, present disclosure can be realized by various forms, and not answered This is construed as limited to the implementation illustrated here, provides these on the contrary and is achieved in that for more thorough and complete geography Solve present disclosure.It should be understood that the attached drawing and being given for example only property of implementation of present disclosure act on, it is not intended to Limit the protection scope of present disclosure.
In the description of the implementation of present disclosure, term " includes " and its similar term should be understood as opening Include, i.e., " including but not limited to ".Term "based" should be understood as " being based at least partially on ".Term " implementation " Or " implementation " should be understood as " at least one implementation ".Term " first ", " second " etc. may refer to difference Or identical object.Hereafter it is also possible that other specific and implicit definition.
Diversified search engine has been had already appeared at present.User can into search engine input inquiry to obtain Query result.For ease of description, the example of user query is described referring first to Fig. 1.Fig. 1 diagrammatically illustrates user's input The diagram 100 of inquiry.As shown in Figure 1, user can input description inquiry in the query frame 120 provided by search engine 110 The query text of information.Query information in this for example can be user and it is expected the problem of understanding.For example, when user it is expected inquiry When whom the wife of famous movie star " Zhang Ming " is, " whom the wife of Zhang Ming is " can be inputted into query frame 120.In another example when with At the time of certain bus is inquired in family expectation when table, " No. 103 bus timetable " can be inputted.Then, search engine 110 can be with Subsequent searches are executed according to the information parsed from inquiry.However, since the language expression of users is accustomed to different, use Family may use diversified language expression in search, for example, may include various oral expressions or again in inquiry Multiple content.This leads to the query information of 110 indigestion user of search engine and then accurately cannot return to inquiry knot to user Fruit.
It has been proposed determining the special entity for including in inquiry based on constraint (for example, entity class and attribute) at present Attribute technical solution, however the entity in inquiring may and be unsatisfactory for constraint condition, thus cause mistake.It also proposes at present User is helped based on search key is prompted the user with to determine the technical solution of the information of inquiry.For example, when user inputs When " Zhang Ming ", the user can be prompted " birthday ", " height ", the attributes such as " first signature song " are in order to user's selection.However, the technology Scheme provides prompt based on limited attribute set predetermined, can not cover the various query informations of users.This When, how to determine that the query information of user becomes a problem to be solved.
In order at least be partially solved the deficiency in above-mentioned technical proposal, according to the exemplary realization of the disclosure, provide A kind of technical solution of query processing.Hereinafter, it will refer to the exemplary realization that Fig. 2 is broadly described the disclosure.Fig. 2 is schematic Show the block diagram 200 of the technical solution of the example implementations query processing according to present disclosure.As shown in Fig. 2, can To receive true inquiry 210 from the user, and a group object 220 and one group of category are determined from inquiry 210 from the user Property 230.Multiple entities and attribute can be respectively included in a group object 220 and one group of attribute 230 in this.
At least one reality of the alternate information of description inquiry can be generated based on a group object 220 and one group of attribute 230 Body attribute is to 240.Entity attribute in this may rely on physical quantities in a group object 220 and one group to 240 quantity Number of attributes in attribute 230.It then, can be for each entity attribute to assessing.According to the exemplary reality of the disclosure Existing mode, can be come in a manner of scoring quantitative evaluation as a result, for example, can be commented with the numerical value in the section 0-100 to determine Point, or discrete way can also be waited to determine scoring using high, medium and low.For example, can be determined based on historical experience each The assessment 250 of entity attribute pair, and select an entity attribute to use (for example, selection scoring is highest) based on assessment 250 In the information 260 of description inquiry.
It is realized using above-mentioned example, the content of text in inquiry 210 inputted by actual analysis user can extract The problem of with user associated potential entity and attribute.Then, by composite entity and attribute and to combined entity attribute To assessing, the information for assessing and then determining the expectation inquiry of user's most probable can be determined based on historical experience.By this method, User's expectation can be accurately obtained to solve the problems, such as.Further, it is also based on acquired entity attribute pair, is searched to construct Index other downstream models in holding up.
According to the example implementations of the disclosure, since entity in this and attribute are not predetermined, but It is directly obtained from user query, may adapt to handle various user query, and can contribute to find new entity- Relation on attributes.It can directly be handled for a large amount of inquiries from the user, and to obtain more accurate result.
Hereinafter, the more details of information of Fig. 3 description in relation to determining inquiry be will refer to.Fig. 3 diagrammatically illustrates root According to the flow chart of the inquiry processing method 300 of the example implementations of present disclosure.At frame 310, it is determined whether receive To inquiry 210, such as inquiry from the user.If it is determined that receiving inquiry 210 from the user, then method 300 advances to Frame 320.At frame 320, a group object 220 and one group of attribute 230 can be extracted from the text of inquiry 210.Hereinafter, will Describe respectively how from inquiry 210 text in extract entity and attribute more details.According to the exemplary realization of the disclosure Mode can execute text analyzing for inquiry 210 to extract one group of keyword from inquiry 210.
Keyword in this is, for example, the notional word in text with certain sense, including name, place name, mechanism name, proprietary Noun etc..For inquiry " whom the wife of Zhang Ming is ", keyword for example may include: Zhang Ming, wife.It then, can be with base The entity in a group object is determined in a set of keyword of extraction.At this point, a group object may include two entities: Zhang Ming, wife Son.For inquiry " No. 103 bus timetable ", keyword for example must include: bus, timetable.
According to the example implementations of the disclosure, attribute library can be pre-defined (for example, attribute dictionary or with other The attribute list of format storage).Attribute dictionary in this may include description candidate attribute associated with inquiry.It can be based on Historical experience carrys out defined attribute dictionary.For example, the certain information that can be frequently inquired based on a large number of users are come defined attribute dictionary. According to the example implementations of the disclosure, attribute dictionary may include: that the users such as wife, timetable, height, birthday may close The information of note.Then, it can be extracted from inquiry 210 and be matched with the text of attribute dictionary using as the attribute in one group of attribute.
For example, attribute may include " wife " for inquiry " what the wife of Zhang Ming cries ".In another example if belonging to " what " property dictionary further include, then one group of attribute may include two attributes at this time: wife, what.In another example for inquiry For " No. 103 bus timetable ", since attribute dictionary includes " timetable ", then one group of attribute may include a category at this time Property, that is, timetable.
In some cases, the inquiry 210 of user's input may include complicated syntactic structure.According to the example of the disclosure Property implementation, for inquiry 210 execute syntactic analysis, generate description inquiry 210 in word between grammer dependence Dependent tree, and a group object and one group of attribute are extended based on dependent tree.It hereinafter will refer to Fig. 4 and describe related language The more details of method dependent tree.Fig. 4 diagrammatically illustrates looking into for one according to the example implementations of present disclosure The block diagram of the syntactic dependency tree 400 of inquiry.
In Fig. 4, the text that each expression of node 410,420,430,440 and 450 is extracted from inquiry 210, and node Between line indicate two texts between grammer dependence.For example, the relationship 462 between node 410 and node 420 Indicate DE relationship, that is, used between the text of former and later two nodes " " connection of word structure.Similarly, in node 420 and node Relationship 464 between 430 also illustrates that DE relationship.Thus, node 410,420 and 430 collectively constitutes a phrase " wife of Zhang Ming Son ".The expression subject-predicate relationship of relationship 466 between node 430 " wife " and node 440 " crying ", and node 440 " crying " and node Relationship 468 between 450 " what " indicates dynamic guest's relationship.
Typically, if between two texts being relationship (referred to as fixed middle relationship, the abbreviation between attribute and centre word For ATT), then attribute plays modification or restriction effect to centre word.It needs to extend centre word using attribute at this time, so as to accurately simultaneously And comprehensively obtain entity/attribute meaning.In the syntactic dependency tree 400 described above with reference to Fig. 4 and there is no fixed middle passes System, thus at this time without extension.
For inquiry " No. 103 bus timetable ", it can determine that a group object includes public affairs using method as described above Vehicle is handed over, and one group of attribute includes timetable.Fig. 5 diagrammatically illustrates being directed to according to the example implementations of present disclosure The block diagram of the syntactic dependency tree 500 of another inquiry.Fig. 5 shows based on analysis inquiry " No. 103 bus timetable " and determines Syntactic dependency tree 500.In Fig. 5, node 510,520,530 is the text for including respectively in inquiry, and relationship 542 and 544 Respectively illustrate the relationship between corresponding node.For example, relationship 542 indicates node 510 " 103 tunnel " and 520 " public transport of node Relationship between vehicle " is surely middle relationship, then can extend the entity " bus " having determined based on node 510 at this time.
Although the relationship 544 between node 520 " bus " and node 530 " timetable " remains as relationship in surely, by In at this time, " timetable " has been labeled as " attribute ", thus is no longer extended.Entity after extension is " 103 tunnel public transport Vehicle ".In this way, it is possible to determine the real content of entity in a manner of more accurate and is comprehensive.At this point,
At frame 330, it is based on a group object 220 and one group of attribute 230, generates the information 260 for being used to describe inquiry extremely A few entity attribute is to 240.At least one entity attribute is to an entity attribute in 240 to including coming from a group object An entity in 220 and an attribute in one group of attribute 230.
Specifically, a category can be selected from one entity of selection in a group object 220 and from one group of attribute 230 Property.Can entity and attribute based on selection, generate an entity attribute pair.For inquiry " what wife of Zhang Ming cries ", institute The group object and one group of attribute extracted can be expressed as follows:
One group object: { Zhang Ming, wife };
One group of attribute: wife, what.
At this point, 4 entity attributes pair can be obtained by composite entity and attribute: (Zhang Ming, wife), (Zhang Ming, it is assorted ), (wife, wife), (wife, what).It will be understood that since entity and attribute should be indicated with different texts, then (wife, wife) can be deleted from above-mentioned entity attribute centering at this time, and finally obtain following three entity attributes pair: ( It is bright, wife), (Zhang Ming, what), (wife, what).
For inquiry " No. 103 bus timetable ", an extracted group object and one group of attribute can be expressed as follows:
One group object: { No. 103 bus };
One group of attribute: { timetable }.
At this point, by composite entity and attribute 1 entity attribute pair can be obtained: (No. 103 buses, timetable).
Return to Fig. 3, at frame 340, at least one entity attribute centering corresponding entity attribute to assessing.Root According to the example implementations of the disclosure, the assessment of each entity attribute pair can be determined based on historical experience.For example, being directed to The given entity attribute pair of at least one entity attribute centering, the scoring of available entity attribute pair and the spy of entity attribute pair Mapping relations between sign.In the operational process of search engine, which kind of shape can be obtained from the historical search of a large number of users The entity attribute of formula is to can obtain higher scoring, and the entity attribute of which kind of form is to can obtain lower scoring.
Here, for some entity attribute for, it can be with the feature of the entity attribute pair as the mark entity The identifier of attribute pair.Further, mapping relations can be the assessment based on one group of sample entity attribute pair and one group of sample The training of the feature of entity attribute pair and obtain.Thus, the feature based on mapping relations and given entity attribute pair can be true Surely the assessment of given entity attribute pair.
According to the example implementations of the disclosure, above-mentioned mapping relations can be trained based on the method for machine learning. For example, some sample entity attributes of the problem of may be selected that correct reflection user during the training period are to training the mapping Relationship, so that the mapping relations can export higher scoring when receiving the input similar to sample entity attribute pair. In another example can choose not some sample entity attributes of the problem of can correctly reflect user during the training period to training this to reflect Relationship is penetrated, so that the mapping relations can export lower comment when receiving the input similar to sample entity attribute pair Point.
According to the example implementations of the disclosure, during subsequent operation, it is also based on subsequently received reality The information of body attribute pair updates the mapping relations.In this way, it is possible to make determining information that can more be reflected in specific time The interior concern the most of section.For example, it is assumed that frequently occurring user query " what wife of Zhang Ming cries " or similar in the recent period Inquiry can then update mapping relations so that higher scoring is provided to (Zhang Ming, wife) for entity attribute, so as to more Accurate mode determines the information of user query.
According to the example implementations of the disclosure, the feature for giving entity attribute pair includes various contents.For example, It may include at least any one in following: the position of the entity of entity attribute centering in queries;The length of entity;Entity category The position of the attribute of property centering in queries;The length of attribute;The ratio of the length of the total length and inquiry of entity and attribute;With And the text distance between entity and attribute;The distance of entity and attribute in dependent tree.
Hereinafter, the more details that Fig. 6 describes the feature in relation to entity attribute pair be will refer to.Fig. 6 is diagrammatically illustrated According to the example 600 of the feature of the entity attribute pair of the example implementations of present disclosure.As shown in fig. 6,610 table of field Show the position of the entity of entity attribute centering in queries, the length of 620 presentation-entity of field, 630 presentation-entity attribute of field The position of the attribute of centering in queries;The length of the expression attribute of field 640;The total length of field 650 presentation-entity and attribute With the ratio of the length of inquiry;Text distance between 660 presentation-entity of field and attribute;And 670 presentation-entity of field and Distance of the attribute in dependent tree.
Hereinafter, it will describe how to determine each of entity attribute pair to (Zhang Ming, wife) is example with entity attribute A feature.It will be understood that entity " Zhang Ming " is located at the 1-2 word in inquiry " what the wife of Zhang Ming cries ", thus can be true The position for determining entity is 1.Entity " Zhang Ming " includes two words, thus the length of entity is 2.Attribute " wife " is in inquiry " Zhang Ming Wife what is cried " in be located at the 4-5 word, thus can determine entity position be 4.Attribute " wife " includes two words, Thus the length of attribute is 2.The total length of entity " Zhang Ming " and attribute " wife " is 4, and the length inquired is 8, thus, entity Ratio with the length of the total length and inquiry of attribute is 4/8=0.5.Text distance between entity and attribute is 4-1=3.
According to the example implementations of the disclosure, the distance of entity and attribute in dependent tree is also based on to determine The numerical value of field 670.Fig. 4 is returned to, due to including 2 relationships between the node 410 of presentation-entity and the node 430 of expression wife 462 and 464, thus can determine that the distance of entity and attribute in dependent tree is 2.Thus, entity attribute is to (Zhang Ming, wife) Feature vector can be expressed as shown in Figure 6 (1,2,4,2,0.5,3,2).
Similarly, it for inquiry " what the wife of Zhang Ming cries ", is also based on aforesaid way and determines following two The feature vector of entity attribute pair: (Zhang Ming, what) and (wife, what).It will be understood that only schematically showing referring to Fig. 6 above An example for having gone out feature vector, according to the example implementations of the disclosure, feature vector can also include it is more or Less dimension.Then, can mapping relations and each entity attribute pair based on acquisition feature vector, to determine each reality The scoring of body attribute pair.
Fig. 3 is returned, at frame 350, after being directed at least one entity attribute to assessing, can be based on commenting Estimate result (that is, scoring) to select an entity attribute to the letter for describing inquiry from least one entity attribute centering Breath.Hereinafter, more details of Fig. 7 description in relation to determining query information be will refer to.Fig. 7 is diagrammatically illustrated according to the disclosure The block diagram 700 of the information that inquiry is determined based on the scoring of entity attribute pair of the example implementations of content.
Entity attribute is shown in FIG. 7 to 710,720 and 730.According to method as described above it is obtained scoring from Low to high sequence is ranked up, then entity attribute is highest to 730 scoring.At this point it is possible to select (Zhang Ming, wife) to make The information 740 solved it is expected for user.For inquiry " No. 103 bus timetable " above, since there is only one at this time A entity attribute, then at this time can be directly by the entity attribute to the information as inquiry to (No. 103 buses, timetable).
It hereinbefore describes how to determine information associated with the query to Fig. 7 referring to fig. 2.However, in some feelings Identified entity attribute really it is expected the problem of understanding to that may not can accurately reflect user under condition.Thus, really Entity attribute is determined to later, post-processing can also be performed, and does not meet expected entity attribute pair to filter out.
According to the example implementations of the disclosure, if the attribute of the entity attribute centering of selection includes predetermined word (such as the word for indicating query), can be to remove predetermined word in dependence.Assuming that attribute includes " whom wife is " similar knot Structure, then can be to delete word as " whom is " in dependence.
It, can be based on the word of the text of the attribute of the entity attribute centering of selection according to the example implementations of the disclosure Property carrys out Filtering entity attribute pair.For example, for inquiry " lip one encloses rubescent and pain ", it is assumed that the entity attribute selected to for (lip, rubescent).It is found by analysis, it is verb property that attribute is " rubescent " at this time.Thus it can consider determining information not It is accurate thus can abandon selected entity attribute pair.
It, can be based on the length of the text of the attribute of the entity attribute centering of selection according to the example implementations of the disclosure Degree, carrys out Filtering entity attribute pair.In this implementation, the threshold value of the text size of attribute can be set.When the entity of selection When the text size of the attribute of attribute centering is more than the threshold value, then selected entity attribute pair can be abandoned.
According to the example implementations of the disclosure, can the entity attribute centering based on selection whether include except one group real Other notional words other than body and one group of attribute, carry out Filtering entity attribute pair.For example, for inquiry " method of bamboo production cup ", Assuming that the entity attribute selected is to for (bamboo, make cup).It further include notional word " side in inquiry by analysis inquiry discovery Method ", and the notional word is not in the entity attribute pair of selection.At this time it is considered that determine information miss inquiry in it is interior Hold, thus selected entity attribute pair can be abandoned.
The multiple implementations for how handling the method 300 of inquiry are hereinbefore described in detail.According to the disclosure Example implementations, additionally provide for determine inquiry information 260 device.Hereinafter, it will refer to Fig. 8 to retouch in detail It states.
