Description

A kind of answer method and system based on tree structure problem
Technical field
The present invention relates to e-commerce field, more particularly to a kind of answer method and system based on tree structure problem.
Background technology
Ecommerce mainly uses internet to be engaged in commercial affairs or activity, during ecommerce is carried out, ecommerce Enterprise needs to set online customer service in network side, provides the online solution of the related query of various commercial affairs for client by internet Answer, commercial affairs correlation query is related to the consulting of the association attributes of commercial product, e-commerce venture's correlated activation consulting and after sale Service consultation etc..With being continuously increased for client consulting amount, limited online customer service can not meet needs, in order to The ever-increasing consulting amount of client is met, answering system is set in network side, the various business of client proposition are automatically replied Related query.
When the answering system set in network side automatically replies the various business correlation query of client proposition, first, In consulting amount, the related query of commercial affairs that up to ten thousand clients are proposed can be replied simultaneously;Secondly, in time, can be with whole day 24 Hour replys the related query of commercial affairs that client is proposed.
At present, the related query of commercial affairs that answering system is generally proposed using matching way acknowledged client end, mainly using two Plant implementation method:
The first implementation method uses the answering system response based on way of search
Answering system based on way of search is received after the query of client transmission, and main utilize searches for key technology pair After query matching, find corresponding response message and be sent to client.
Search for key technology and mainly utilize reverse indexing mode, reverse indexing is called inverted index, and this data structure is deposited Store up information and the mapping relations of information position certainly in one or more documents, that is, full-text search.When response system System is received after the query of client transmission, query index is set up using query information as text, using reverse indexing mode The problem of being fitted on correspondence, is then sent to client by the response message of the set correspondence problem.In this process, query Information can be multiple phrases, by combining method of calling, and the accuracy rate that Secondary Ordering Algorithm improves matching is aided with index.
Answering system based on way of search has the answering system based on full-text index engine lucene, based on full text rope The models such as the solr of secondary encapsulation can also be carried out on engine lucene.
Fig. 1 is the method flow diagram that the answering system of the prior art based on way of search realizes response, its specific step Suddenly it is:
Step 101, the query for receiving by internet client input;
Step 102, to received client query use morphological analysis Language Processing, obtain after Language Processing doubt Ask;
Step 103, to after Language Processing query carry out syntactic analysis, obtain query information;
Step 104, using query information as text query index is set up, the database into answering system finds matching Multiple problems and corresponding response message;
Because query information can be multiple, thus index matching the problem of be also include multiple problems and it is corresponding should Answer information;
Step 105, quadratic dependence sequence is carried out to obtained multiple problems and corresponding response, obtain setting number The problem of degree of correlation highest and corresponding response message;
Step 106, corresponding response message the problem of the degree of correlation highest for setting number by internet is sent to visitor Family end.
