Example two
Please refer to fig. 2, which is a flowchart illustrating a user intention recognition method according to a second embodiment of the present invention, including the steps of:
step S11, obtaining a question sentence sent by a user aiming at a preset fixed sentence pattern, and obtaining a fixed word stored in the preset fixed sentence pattern;
wherein the word-separating sentence includes a plurality of questioning words, and the preset fixed sentence pattern is a sentence beginning with "how" or ending with "how to do", for example, "how to raise the attention of children? "," how do children's attention is not high? "therefore, the fixed words in this step are" how "and" how to do ";

Step S21, matching the words of the question sentence without the fixed words with a local word library, and segmenting the question sentence according to the matching result to obtain the segmented words;
wherein the word-separating sentence includes a plurality of question words, for example, when the question sentence is "how to raise the attention of the child? If the word is 'how, improving, child, attention' and 'how' is a sentence component which is not divided;
step S31, matching the question words with a locally stored coding database to obtain question codes;
wherein, the corresponding code of the word segmentation in the code database is:
increase-tigao 1; child-haizi 1; de 1; attention-zhuyili 1
Step S41, the question codes are sequentially connected according to the order of the question words to obtain a coded sentence;
wherein, the corresponding coding sentence is 'how to tigo 1 haiizi 1de1zhuyili 1';
step S51, matching the coding sentence with the question-answer library and judging whether a matching result exists;
the question-answer library is provided with a plurality of specific question sentences which are used for asking the method for asking something and started in 'how' or ended in 'how' and corresponding code combinations so as to increase the matching success probability;
preferably, at least 1 special question of each matter is coded and combined to ask the method for the matter to start with 'how' or end with 'how' so that the matter is 'just title';
for example, the codes of the question-answering library for how to tigo 1haizi1de1zhuyili1 are combined into a semantic library a, which includes the codes:
firstly, the method comprises the following steps: how tigo 1haizi1de1zhuyili 1; how tigo 2haizi2de2zhuyili 2; how tigo 3haizi3de3zhuyili 3; how is the tigoanhanidinezhuyiliin, wherein M, N, A represents a positive integer greater than or equal to 1, how is sentence fixed
the words corresponding to the tigao 2-tigaoN codes may be:
(1) "enhanced" homophones or mispronounced characters, such as: "body height";
(2) the synonyms of "increase" such as: "lift";
(3) the homonym word of "raise" (i.e. the word which does not greatly affect the sentence meaning of the whole sentence after replacing "raise") is as follows: "reinforcement", "lifting", "training", etc.;
the same improvement on the same homonym heterotypic or mispronounced characters, similar meaning words and homonymous meaning words is achieved for words corresponding to the haiizi 2-haiizin codes, such as: "kids", "children", "girls", etc.;
de2～deN；
the theory of the words corresponding to zhuyili 2-zhuyiliN codes on homophones, allopathic or mispronounced characters, similar meaning words and similar meaning words is improved as same as that of the words;
the semantic library A comprises the following codes:
II, secondly: what is what hapizi 1zhuyili1bu1gao1 should be, and the corresponding sentences are encoded as follows: how do children have low attention? (ii) a haizi2zhuyili2bu2gao 2; haiizizhuyiilnbugaon, wherein the principle is the same as above;
the semantic library A comprises the following codes:
thirdly, the method comprises the following steps: what hapizi 1de1zhuyili1bujizhong1 does is, the corresponding sentences are encoded as follows: how do the children's attention not concentrate?
The semantic library A comprises the following codes:
n: in principle, sentences are all special questions for asking the questions of the method beginning with 'how' or ending with 'how to do', the semantics are the same, but the arrangement and combination of the words are different;
in semantic library a, for "how do you raise the attention of children? In the coding combination of the special question for asking the method, the corresponding coding of how to quickly promote the attention of the child is used as the positive title of how to kuaisu1tigao1haizi1de1 zhuyilii 1, and the others are matching solutions;
in the step, specific questions of the method for asking questions about what starts or what ends of the method are collected manually, and the semantic library where the codes are located is built by applying synonyms, confusing words, characters and the like, and matching solutions and titles are determined;
in this step, the questioner is guided to treat the question rationally by manually setting the form of the "positive title". Such as: when the user searches for "children do not learn how to play well", the corresponding positive title may be: how to help children change habits of greeting and not learning or how to cultivate learning interests of children, so that the intention of the users is recognized, a good teaching function is also played, and the work efficiency of the users is greatly improved;
when the judgment result of the step S51 is yes, step S61 is performed;
step S61, displaying the matched matching solution and the positive title;
for example, when a user asks: "yesterday bought a pair of shoes in the market, the merchant did not invoice and worried about how can not deal with after sale? "the existing computer technology still has difficulty in providing satisfactory results for users through a large number of algorithms.
In this embodiment, the user may be guided to ask a question: "how do the merchant do not give invoices? The problem that the user does not buy shoes after selling is solved, the accuracy of user intention identification is improved, and the time of the user is greatly saved;
further, it should be noted that:
(1) in the specific question asking the method at the beginning of ' how ' or ending of ' how do ', the beginning of ' how ' can be replaced by question pronouns such as ' how ' and ' how
(2) In the specific question asking about the method beginning with "how" or ending with "how to do", the "how to do" at the end of the sentence may be replaced by question pronouns such as "how to do", and the like.
(3) In the specific question sentence which asks the method at the beginning of 'how' or at the end of 'how to do', the 'how' of the sentence head and the 'how to do' of the sentence tail can be coded outside the sentence meaning;
in the embodiment, the questions are limited by the specific question beginning with 'how' and ending with 'how' and the semantic expression range is greatly limited by the specific question ending with 'how' and 'how' so that the thinking of the questioner is combated, the questions are more targeted by the method, the workload of an answerer is reduced, the accuracy of answering the questions is improved, the information exchange cost is reduced on the whole, the subsequent matching and marking aiming at the coding of the questions are effectively facilitated by designing the participles of the question, the intention of the user is accurately inquired by designing the participles marked by the coding and the local question-answering library, the answer result is inquired according to the intention, and the identification efficiency aiming at the intention of the user is effectively improved.
