In the prior art, when identifying a synonymous text, auxiliary processing needs to be performed on the text by depending on auxiliary tools such as a word segmentation tool, part of speech analysis, sentence template extraction and the like to obtain core words, and whether the two core words are synonymous or not is determined by an editing distance between the two core words. The edit distance refers to the number of times a character string needs to be changed into another character string, and the edit distance may represent the difference between the two character strings. When the editing distance between two words is smaller than or equal to a preset value, determining the two words as synonyms; and when the edit distance between the two words is larger than a preset value, determining the two words as non-synonyms. In reality, the non-synonym pair with a small editing distance exists, so that the recognition accuracy of the synonym text is low.

It will be further understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, or sections, these elements, components, or sections should not be limited by these terms.

Fig. 1 is a schematic flow chart of a method for prompting a synonymous text according to the present invention, where the synonymous text refers to a text having the same or similar meaning as an input text, and as shown in fig. 1, the method includes the following steps:
s1, dividing the input text into word units;
wherein the input text may be a single word, such as a keyword or the like input by the user. Or a phrase consisting of a plurality of words. The word unit can be specifically a Chinese word, an English word and the like. The invention can adopt word segmentation tools (such as a Hanlp word segmentation device, an Ansj word segmentation tool and the like) to segment the input text into word units.
S2, determining a target word unit from the word units according to the segmentation condition of the input text,
specifically, if the input text is a single word in step S1, the segmentation condition of the input text is as follows: and when the input text is segmented into only one word unit, taking the only one word unit as a target word unit.
If the input text is a phrase in step S1, the segmentation condition of the input text is: and when the input text is segmented into at least two word units, selecting one of the at least two word units as a target word unit according to the part of speech and/or the word frequency. The word frequency refers to the frequency of word units appearing in a predetermined corpus or a predetermined document. When the part of speech and the word frequency are simultaneously used for determining the target word unit, the priority of the part of speech and the priority of the word frequency are preset, for example, the priority of the part of speech is higher than the priority of the word frequency, the target word unit is selected according to the part of speech, and if the parts of speech of all the word units are the same, the target word unit is selected according to the word frequency. Taking the example of selecting the target word unit according to the part of speech, wherein the part of speech may include: nouns, adjectives, verbs, and words other than the three parts of speech, the present invention can preset the priority of each part of speech, such as: the priorities of nouns, adjectives, verbs, and words other than the three parts of speech increase in order. And then selecting the word unit with the highest word priority as the target word unit. For example, the user inputs "no time", which is divided into two word units of "no" and "time", and the part of speech priority of "no" is higher than that of "time", and then "no" is the target word unit.
S3, obtaining candidate words corresponding to the target word unit through a preset model to form a candidate set,
wherein the candidate word is a synonym or a synonym of the target word unit; the method comprises the steps of training a plurality of word2vec models by obtaining different corpora as a training set; and obtaining candidate words corresponding to the target word unit through each trained word2vec model to form a candidate set. Thus, a target word unit has a plurality of candidate sets, and candidate words in each candidate set may be the same or different. Multiple word2vec models trained on different corpuses guarantee the comprehensiveness of the candidate words.
When each word2vec model obtains a candidate set of a target word unit, firstly inputting the target word unit into a trained word2vec model to obtain a word vector of the target word unit output by the word2vec model; acquiring candidate word vectors with the similarity between the word vectors and the target word unit smaller than a threshold value; and converting the candidate word vectors into corresponding candidate words to form a candidate set. Where the word2vec model is a group of models used to generate word vectors. After training is complete, the word2vec model may be used to map each word to a vector, which may be used to represent word-to-word relationships. In the invention, the similarity of the word vectors can be calculated by the Euclidean distance, the cosine distance, the edit distance, the Hamming distance and the like between the two.
For example, as shown in fig. 2, taking an example of obtaining a candidate set of a target word unit by using three word2vec models, firstly, training the three word2vec models by using different corpora, for example: the method comprises the steps of training a first word2vec model by adopting open-source corpora, training a second word2vec model by adopting a first corpus (such as a juvenile subject corpus) inside an enterprise, and training a third word2vec model by adopting a second corpus (such as a high school subject corpus) inside the enterprise. If the text input by the user is a test paper, the test paper is a target word unit, and the test paper is input into each trained word2vec model. Each word2vec model outputs a word vector of the test paper, calculates Euclidean distances between the word vector of the test paper and other word vectors to obtain similarity between the word vector of the test paper and other word vectors, takes the other word vectors with the similarity smaller than a threshold value as candidate word vectors, and converts the candidate word vectors into candidate words to form a candidate word set. For example, the candidate word set of the "test paper" obtained by the first word2vec model is: paper, examination questions, test paper, true questions, examination, interim, early, end, and exercise questions. The candidate word set of the test paper obtained by the second word2vec model is as follows: examination questions, examination papers, examinees, examination paper reading, examination questions, composition, examination, pen test, question setting and examination room. The candidate word set of the test paper obtained by the third word2vec model is as follows: the test paper is composed of a small section, a paper, an end-of-term test paper, an interim test paper, a monthly exam paper, a test question, a test coupon.
S4, sorting the candidate words in the candidate set to obtain a comprehensive sorting candidate set corresponding to the target word unit;
in a mode of sequencing candidate words in a candidate set, a weighted sequencing mode is adopted, and a candidate set output by each word2vec model is obtained; determining the total weight of the candidate words according to the preset weight of the candidate words and the arrangement positions of the candidate words in each candidate set; and sorting the candidate words in each candidate set according to the total weight of the candidate words. Therefore, the candidate words output by different word2vec models are sorted according to the synonymy recognition accuracy between the candidate words and the target word unit, and the synonymy recognition accuracy of the target word unit is improved. The arrangement positions of the candidate words in each candidate set may be arranged according to the similarity between the word vector of the candidate word and the word vector of the target word unit.
Specifically, the total weight Pi of the candidate word i can be obtained by the following formula:
Pi＝pi×[rank(Ai)+rank(Bi)+…+rank(Ni)]
wherein pi is a preset weight of the candidate word i, rank (ai) is an arrangement position of the candidate word i in the word2vec model output candidate set with the number of A, rank (Bi) is an arrangement position of the candidate word i in the word2vec model output candidate set with the number of B, and rank (Ni) is an arrangement position of the candidate word i in the word2vec model output candidate set with the number of N.
Taking the candidate word "test question" in fig. 2 as an example, assuming that the preset weight of the candidate word "test question" is 0.9, the candidate word "test question" is ranked second in the first word2vec model, first in the second word2vec model, and eighth in the third word2vec model, then the total weight of the candidate word "test question" is: 0.9 × (2+1+ 8).
And S5, prompting the synonymous text of the input text according to the segmentation condition of the input text and the comprehensive sorting candidate set.
Specifically, if the input text is a single word in step S1, the segmentation condition of the input text is as follows: the input text is segmented into only one word unit, and the step comprises the following steps:
s51, filtering out target words meeting conditions from the comprehensive sorting candidate set according to preset word length, preset part of speech and preset word frequency;
for example, the preset word length may be set as: greater than 1 byte and less than 4 bytes; the preset part of speech may be set to be the same as the part of speech of the target word unit, and the preset word frequency refers to the frequency of occurrence of the candidate word in a predetermined corpus or a predetermined document, and may be specifically set according to a training sample of the word2vec model.
And S52, prompting the target words according to the sequence of the target words in the comprehensive sorting candidate set.
Specifically, the target words may be sequentially displayed from front to back according to the order of the target words in the comprehensive ranking candidate set.
If the input text is a phrase in step S1, the segmentation condition of the input text is: the input text is segmented into at least two word units, and the step includes:
s501, acquiring candidate words N before the total weight in the comprehensive ranking candidate set;
wherein, N can be set according to the needs of users.
S502, combining other word units segmented from the input text with the candidate words N before the total weight to obtain N candidate texts;
taking the input text "what time" as an example, it is segmented into "what" and "time", the "what" being the target word unit, and the "time" being the other word units segmented from the input text. If "what" corresponds to the candidate word at the top 9 of the total weight in the comprehensive ranking candidate set: any, what, other, what, each, where, various, everything; then 9 candidate texts are obtained: any time, what time, other times, which times, each time, where time, various times, all times.
S503, sorting the candidate texts according to the historical occurrence frequency of the candidate texts;
the historical frequency of occurrence refers to the frequency of occurrence in the historical query documents. And if the historical occurrence frequency of a plurality of candidate texts is zero, sequencing the candidate texts with the historical occurrence frequency of zero according to the similarity between the word vectors corresponding to the candidate words and the word vectors corresponding to the target word unit.
S504, presenting the candidate texts according to the sequence of the candidate texts.
