Detailed Description
The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the disclosure and that no limitation of the disclosure is intended. It should be further noted that, for ease of description, only some of the structures associated with the present disclosure are shown in the drawings, rather than the entire structure.
In the following embodiments, optional features and examples are provided in each embodiment, and various features described in the embodiments may be combined to form multiple alternatives, and each numbered embodiment should not be regarded as only one technical solution.
Example one
Fig. 1 is a flowchart of a word recommendation method provided in an embodiment of the present disclosure, where this embodiment is applicable to a word recommendation situation, and the method may be executed by a word recommendation apparatus, where the apparatus may be composed of hardware and/or software, and may be generally integrated in a device having a word recommendation function, where the device may be an electronic device such as a server, a mobile terminal, or a server cluster. As shown in fig. 1, the method specifically includes the following steps:
at least one round of dialog between the user and the machine is obtained, step 110.
In this embodiment, when a user needs a word to describe a current situation or a certain phenomenon, at least one round of conversation with the machine is performed to describe a purpose, paraphrase, or related word, etc. In this embodiment, the process of acquiring at least one turn of dialog between the user and the machine may be: collecting voice information input by a user, and performing semantic recognition on the voice information to obtain semantic information; determining feedback information according to the semantic information; acquiring new voice information input by a user according to the feedback information, and performing semantic recognition on the new voice information to obtain new semantic information; and judging whether a command for stopping the conversation is detected, if not, determining new feedback information according to the new semantic information, and returning to execute the operation of collecting new voice information input by the user according to the feedback information until the command for stopping the conversation is detected.
The manner of detecting the instruction to stop the dialog may be that voice information input by the user is not collected within a set time, and the set time may be any value between 5 and 10 seconds. Specifically, a user inputs description or paraphrase about a target word through voice, the machine performs semantic recognition on collected voice information, whether feedback information is generated or not is judged according to the semantic information, namely whether the description needs to be supplemented by the user is judged through the semantic information, if yes, the feedback information is generated, the user inputs supplemented new voice according to the feedback information, and the new voice information is subjected to semantic recognition to obtain new semantic information. If the command for stopping the conversation is not detected, whether the user needs to continue supplementing the description is judged according to the new semantic information until the command for stopping the conversation is detected, and at least one round of conversation between the user and the machine is obtained.
Step 120, at least one keyword in at least one round of conversation is extracted.
In this embodiment, keywords are extracted from sentences spoken by the user in at least one pair of dialogs. Extracting at least one keyword in at least one round of conversation, comprising: obtaining sentence templates corresponding to sentences spoken by a user in at least one pair of conversations; and determining keywords respectively corresponding to each sentence spoken by the user according to the sentence template to obtain at least one keyword.
The sentence template is composed of a plurality of word slots, and each sentence template specifies that the words in the word slots are set as the keywords of the current sentence. The sentence patterns can comprise judgment sentences, passive sentences, prepositive object, component omission sentences, prepositive object in negative sentences, prepositive object in question sentences, prepositive object in prepositive object sentences, postpositive stationary sentences, postpositive idiom and the like, and the sentence patterns can comprise cardinal-predicate sentences, non-cardinal-predicate sentences, passive sentences, inverted sentences, accompanying sentences, linkage sentences and the like. For example, for a decision sentence, the sentence is "the subject-predicate" if "A is B", then the words in the object will be determined as keywords in the decision sentence.
Optionally, determining the keywords corresponding to each sentence spoken by the user according to the sentence template may be implemented in the following manner: segmenting the current sentence spoken by the user according to the sentence pattern and/or the sentence pattern to obtain at least one word; and respectively filling at least one word into a word slot of a sentence template corresponding to the current sentence to obtain a keyword corresponding to the current sentence.
Specifically, after the sentence spoken by the user is divided into at least one word according to the sentence pattern and the sentence pattern, the at least one word obtained by the division is filled into the word slot of the corresponding sentence template, so as to obtain the keyword corresponding to the current sentence. For example, assuming that a sentence pattern of a sentence spoken by a user is a subject predicate, the sentence is divided to obtain words corresponding to the subject, words corresponding to the predicate, and words corresponding to the object, and the three words are filled in word slots in a subject predicate template, and if words located in the subject word slots and the predicate word slots in the subject predicate sentence template are specified as keywords, words corresponding to the subject and the predicate in the sentence are the keywords.
And step 130, searching the target words in a preset tree-shaped library according to at least one keyword, and pushing the target words to the user.
The preset tree-shaped library can be obtained by collecting a Chinese word set and adding a label to each word in the word set according to the word sense; and carrying out grade division on the word set according to the label to obtain a preset tree-shaped library.
The way of collecting chinese words may be from a thesaurus, or an official dictionary. Specifically, at least one tag is added to a word according to the word sense of the word, and a word set may be ranked according to the number of tags, for example: the word that has a label is one-level word, and the word that has two labels is the second grade word, and the word that has three labels is tertiary label. For example: the label of running is "run", and is a first-level word, the label of "thousand miles a day" is "run + fast", and is a second-level word, and the label of "fasthorse jiabian" is "run + fast + animal", and is a third-level word.
Searching a target word in a preset tree-shaped library according to at least one keyword, wherein the searching comprises the following steps: if the number of the keywords is multiple, ranking the multiple keywords; and searching step by step in a preset tree-shaped library according to the sorted keywords to obtain the target words.
When a plurality of key words exist, the key words are firstly sorted according to the grades, and finally, the sorted key words are searched step by step in a preset tree-shaped library to obtain the target words. The ranking of the keywords may be ordered according to the parts of speech of the words, for example: the real word is ranked higher than the particle word, and the ranking from high to low for the real word may be: nouns, verbs, adjectives, quantifiers, and the like, and the levels of the fictional words can be adverbs, linguistics, conjunctions, and the like from high to low. For the keywords with the same part of speech, the rank can be determined according to the number of words of the words, and the higher the number of words, the higher the rank. And if the parts of speech of the two keywords are the same and the number of words is also the same, determining the grade according to the sequence of the first letter. For example, assume that the ordered keywords are: when the user runs, fast runs and resembles a bird, firstly, words related to running are searched according to the running, then words of the fast runs are searched by combining the fast running, and finally, the searching is continued by combining the bird-liked word to obtain the target word of 'walking as if flying'.
Optionally, searching for the target word in the preset tree library according to at least one keyword includes: acquiring a limiting condition of a target word; and filtering the target words according to the defined conditions.
Wherein the limitation condition may be a limitation on the number of digits. And (4) assuming that the limiting condition is 4-word words, filtering out non-four-word words in the target words to obtain the final target words. And after the target words are obtained, pushing the target words to the user.
According to the technical scheme, at least one round of conversation between a user and a machine is obtained, at least one keyword in at least one round of conversation is extracted, and finally, the target word is searched in the preset tree-shaped library according to the at least one keyword, and the target word is pushed to the user. According to the word recommending method disclosed by the embodiment, keywords in the sentence are obtained based on multiple rounds of conversations between the user and the machine, the target word is searched in the preset database according to the keywords and pushed to the user, and the word recommending accuracy is improved.
