In one or more embodiments of the present application, as shown in fig. 4, there is a synonym relationship, a paranym relationship, and an anti-synonym relationship in the constructed idiom knowledge graph, and if idiom entity a, idiom entity B, idiom entity C, and idiom entity D are idiom entities in the idiom knowledge graph, and idiom entity a and idiom entity B are synonym relationships, idiom entity a and idiom entity C are paranym relationships, and idiom entity a and idiom entity D are anti-synonym relationships, then the idiom entity a and idiom entity B should have identical feature labels.
Step 506: and acquiring a problem statement input by a user, performing Chinese word segmentation on the problem statement, and acquiring text data corresponding to a target idiom in the problem statement.
In one or more embodiments of the present application, after obtaining a question sentence input by a user, the system firstly performs word segmentation on the question sentence through a chinese word segmentation technology of natural language processing, thereby extracting the target idiom from the question sentence, and obtaining a substring corresponding to the target idiom, i.e. text data.
Step 508: and acquiring idiom entities matched with the text data corresponding to the target idiom from the corpus database based on the text data corresponding to the target idiom and a pattern matching algorithm so as to identify the target idiom.
In one or more embodiments of the present application, the system performs matching with a substring corresponding to the target idiom as a mode (keyword) based on a pattern matching algorithm, and with the corpus database as a target, and searches the corpus database for the target idiom so as to identify the target idiom.
Step 510: and determining at least one characteristic label corresponding to the target idiom in the idiom knowledge graph.
In one or more embodiments of the present application, after determining the target idiom, the system further determines at least one feature tag corresponding to the target idiom through an idiom knowledge graph, where the feature tag is already marked and manually audited, and is used for marking attribute or description information of the target idiom, for example, meaning of the idiom "darkness ageing bin" is "confused enemy from front, used for covering an attack route of the person, and makes a sudden attack from a flank, which is a surprise of clashing the person and wonder, and by extension, means to confuse the person with obvious actions, make an unprecedented strategy, and also say to perform activities in a hidden manner. ", its signature may include" military "," purported "and" surreptitious ", etc.
Step 512: and acquiring at least one idiom entity with the identical feature tag with the target idiom from the idiom knowledge graph as a candidate idiom based on at least one feature tag corresponding to the target idiom, and generating an idiom recommendation list corresponding to the at least one candidate idiom.
In one or more embodiments of the present application, since a plurality of feature labels are set for each idiom entity in the idiom knowledge graph, the system only needs to match the feature labels in the idiom knowledge graph, so as to obtain at least one idiom entity having the same feature label as the target idiom as a candidate idiom, and generate an idiom recommendation list corresponding to the at least one candidate idiom, so that the selected candidate idiom and the main morpheme of the target idiom can be ensured to be the same.
Step 514: and carrying out similarity calculation on the word embedding vector corresponding to the target idiom and the word embedding vector corresponding to each candidate idiom in the idiom recommendation list respectively to obtain a similarity value corresponding to each candidate idiom and the target idiom.

By utilizing the connection between the idioms and the corresponding feature labels, the method and the device distinguish the synonyms from the synonyms, so that the synonyms required by the user are distinguished, the mixed synonyms are filtered, and the candidate idioms in the idiom recommendation list can be interchanged with the target idioms under any context.
Fig. 6 shows a method for generating a idiom synonym list according to an embodiment of the present disclosure, wherein the generating method of the idiom synonym list is described by taking generation of the idiom synonym list as an example, and the method includes steps 602 to 620.
Step 602: the method comprises the steps of obtaining structured data from a preset corpus database, wherein the structured data comprises a plurality of idiom entities, a plurality of feature tags, idiom attribute information, semantic relation information among the idiom entities and tag relation information among the idiom entities and the feature tags.

Step 604: and constructing a idiom knowledge graph according to the structured data, so that the idiom knowledge graph contains idiom entities with semantic relations, and attributes and at least one feature label corresponding to each idiom entity.
In one or more embodiments of the present application, as shown in fig. 4, there is a synonym relationship, a paranym relationship, and an anti-synonym relationship in the constructed idiom knowledge graph, and if idiom entity a, idiom entity B, idiom entity C, and idiom entity D are idiom entities in the idiom knowledge graph, and idiom entity a and idiom entity B are synonym relationships, idiom entity a and idiom entity C are paranym relationships, and idiom entity a and idiom entity D are anti-synonym relationships, then the idiom entity a and idiom entity B should have identical feature labels.
Step 606: and acquiring word embedding vectors corresponding to each idiom entity in the idiom knowledge graph from a preset Chinese character word and sentence embedding corpus.
In one or more embodiments of the present application, word embedding vectors corresponding to chinese words and phrase entities including idioms trained in advance by a model are already stored in an existing chinese word and sentence embedding corpus, and the system can load word embedding vectors corresponding to all limited idiom entities in the idiom knowledge graph for subsequent similarity calculation.
Step 608: and acquiring a problem statement input by a user, and identifying a target idiom from the problem statement input by the user.
In one or more embodiments of the present application, in a case where a user needs to find a synonym of a specific target idiom when inputting text through a terminal device, the user may directly ask a question to a system in a authoring tool, the system may obtain a question sentence input by the user, and identify the target idiom that the user wants to find the synonym from the question sentence input by the user, for example, in a case where the user needs to find a synonym idiom of a target idiom "dark place" to replace, the user may input a synonym of a question sentence "dark place" to ask the system, and the system may obtain the synonym of a question sentence "dark place" and identify the target idiom "dark place" from the synonym of a question sentence "dark place".
Step 610: and acquiring at least one candidate idiom with the same characteristic label as the target idiom from a preset idiom knowledge graph, and generating an idiom recommendation list corresponding to the at least one candidate idiom.
In one or more embodiments of the present application, a idiom knowledge graph is constructed by a system using a idiom knowledge graph construction method based on feature labels, after the system acquires the target idiom of a user question, the system matches at least one candidate idiom having the same feature label as the target idiom in the idiom knowledge graph through the feature label already marked in the idiom knowledge graph by the target idiom, and generates an idiom recommendation list corresponding to the at least one candidate idiom.
Step 612: and determining word embedding vectors corresponding to the target idioms and word embedding vectors corresponding to each candidate idiom in the idiom recommendation list based on the Chinese character word and sentence embedding corpus.
In one or more embodiments of the present application, the system determines, after loading, a word embedding vector corresponding to the target idiom and a word embedding vector corresponding to each candidate idiom in the idiom recommendation list from word embedding vectors corresponding to all limited idiom entities in the idiom knowledge graph.
Step 614: and based on a similarity algorithm, respectively calculating cosine similarity between the word embedding vector corresponding to the target idiom and the word embedding vector corresponding to each candidate idiom.
In one or more embodiments of the present application, the system calculates, based on a similarity algorithm, cosine similarity of a word embedding vector corresponding to the target idiom and a word embedding vector corresponding to each candidate idiom, where cosine similarity uses a cosine value of an included angle of two vectors in a vector space as a measure of a difference between two individuals, the cosine similarity is still kept as "1 when the two individuals are identical" in a high-dimensional case, is 0 when the two individuals are orthogonal, and is "1" when the two individuals are orthogonal, and compared with a distance measure, the cosine similarity is more focused on a difference of two vectors in a direction, rather than a distance or a length, and the formula is as follows:
in particular, since the cosine similarity measures the included angle of the space vector, and the difference in the direction is more than the position, there is also a case that the cosine similarity is high but the two idiom entities are anti-ambiguities, so that the feature labels are needed to ensure that the main morphemes between the candidate idioms and the target idioms are the same.
Step 616: and comparing the cosine similarity of the word embedding vector corresponding to the target idiom with the cosine similarity of the word embedding vector corresponding to each candidate idiom with a similarity threshold, and judging whether the cosine similarity of the word embedding vector corresponding to the target idiom and the word embedding vector corresponding to the candidate idiom is larger than or equal to the similarity threshold. If yes, go to step 618, if not, go to step 620.
Step 618: and reserving the candidate idioms in the idiom recommendation list.
In one or more embodiments of the present application, when the cosine similarity between the word embedding vector corresponding to the target idiom and the word embedding vector corresponding to the candidate idiom is greater than or equal to the similarity threshold, the similarity between the target idiom and the candidate idiom is considered to be higher, and the target idiom and the candidate idiom may be determined to be synonyms, so that the candidate idiom is reserved in the idiom recommendation list.
Step 620: and removing the candidate idioms from the idiom recommendation list.
In one or more embodiments of the present application, in a case where cosine similarity between the word embedding vector corresponding to the target idiom and the word embedding vector corresponding to the candidate idiom is smaller than the similarity threshold, it is considered that the similarity between the target idiom and the candidate idiom is weaker, and is insufficient to determine that the target idiom and the candidate idiom are synonyms, so that the candidate idiom is removed from the idiom recommendation list.
Alternatively, the similarity threshold may be 0.9.
According to the method, cosine similarity is calculated on the target idiom and each candidate idiom by using the word embedding vector, and the cosine value of the included angle of the two vectors in the vector space is used as the size for measuring the difference between two idiom entities, so that whether the two idioms are synonyms or not can be accurately and reliably judged.
