Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.

As shown in Figure 1, the official documents and correspondence Improvement may include following steps:

Step S102, the content of text of official documents and correspondence to be rewritten is obtained.

In specific implementation, official documents and correspondence to be rewritten may include the official documents and correspondence of marketing to be promoted, and can also be and is promoting marketing In official documents and correspondence, for example in promoting the function of marketing a APP (application program), the content of text of initial official documents and correspondence usually comes The APP details about the APP function characteristics filled in from developer or developer, the details stress to show the core for having APP At this moment heart function just will include the official documents and correspondence of APP details, carry out in the advertisement position being placed in the media such as Website page, the APP page Marketing is promoted, to attract the attention of user by the content of text shown, read, or even clicks the link of official documents and correspondence, into Enter specific marketing instruction page etc..

It should be noted that the word content that can also include from official documents and correspondence obtains out content of text, it is not reinflated here Explanation.

Step S104, word segmentation processing is carried out to the content of text, obtains several participles.

In specific implementation, word segmentation processing is carried out using dictionary, wherein dictionary can be the dictionary manually established, and dictionary can To be the dictionary for having collected the vocabulary for needing to be rewritten official documents and correspondence fields, it can quickly and accurately be treated change by dictionary in this way The content of text for writing official documents and correspondence is matched, and several participles are marked off, and participle obtained so also has with official documents and correspondence fields Biggish correlation.

In some embodiments, can also head and the tail identifier be added to the participle, head and the tail identifier can be passed through in this way To reflect position of the participle in sentence, moreover it is possible to reflect the relationship of the participle with front and back participle, it is subsequent so as to be convenient for Rewriting operation.

Step S106, according to the specified term pair of at least one of the domain knowledge base of the official documents and correspondence fields to be rewritten Several participles are rewritten.

Wherein, the domain knowledge base is the knowledge pre-established according to the specified term in the text data of corpus Library, the specified term are the term in official documents and correspondence field with business scenario meaning.

It should be noted that being also commonly referred to as the reality in the field with the term of business scenario meaning in official documents and correspondence fields The corresponding term of body knowledge, wherein entity mobility models are the knowledge of the entity in field with specific meanings, so specified term can For the corresponding word of entity mobility models in field；One or more participle is rewritten in addition, can be, when being multiple When participle is rewritten, with regard to carrying out rewriting participle using corresponding excessively a specified term.

For example, the corresponding specified term of entity mobility models may include having in marketing domain: festivals or holidays are (such as: National Day, mid-autumn Section etc.), popular cyberspeak (such as: pricking the old iron of the heart, vertical flag), marketing hot word (such as: also not fastly action, it is slow with one's hands without) Deng.

It in some embodiments, can be to the participle for obtaining out from the content of text of official documents and correspondence to be rewritten, using replacement side Formula, which is realized, rewrites, that is to say, that can be by domain knowledge base, with participle accessed from the content of text of official documents and correspondence to be rewritten The term (i.e. specified term) of corresponding entity mobility models, the directly accessed participle of replacement, and then obtain in new text Hold, not only remained the meaning of original text content in this way, but also the similar core meaning can be expressed by new content of text, enriches The expression way of content.

For example, the similar corresponding marketing hot word " not taking action fastly also " of the meaning at this moment can be used when segmenting as " quickly take action ", Or the replacement such as " quick-moving to have ", " slow with one's hands nothing ".

It in some embodiments, can also be to the participle for obtaining out from the content of text of official documents and correspondence to be rewritten, using slotting Enter mode and realize rewriting, that is to say, that can be and accessed from the content of text of official documents and correspondence to be rewritten by domain knowledge base Participle has the corresponding term of entity mobility models being closely connected, and is inserted into the anterior/posterior position of accessed participle, and then obtain To new content of text.

For example, current date has closed on National Day, and the marketing official documents and correspondence traveled is want to carry out favorable sale before festivals or holidays At this moment National Day, the corresponding term of preferential movable entity mobility models etc. can be inserted into the content of text of tourism official documents and correspondence by activity In, specifically it is inserted into the adjacent position accordingly segmented.

It in some embodiments, can also be to the participle for obtaining out from the content of text of official documents and correspondence to be rewritten, using deleting The mode of subtracting realizes rewriting, that is to say, that can according to the specified term in domain knowledge base, will with entity mobility models correlation (such as Similarity) low word, it is deleted away from participle, to only be left have the participle being closely connected with entity mobility models.

In some embodiments, it can also be the term of the related entity mobility models according to domain knowledge base, to extract The corresponding term of entity mobility models in the content of text of official documents and correspondence to be rewritten, then again using the term extracted as described point Word not only ensure that participle was closely related with official documents and correspondence in this way, but also can guarantee the quantity of participle in suitable range.

It in some embodiments, can also be according to the corresponding head and the tail marker character of the participle, to rewrite the participle, specifically The rewrite methods such as replacement, insertion can be used in implementation, which is not described herein again.

Step S108, the revised content of text is carried out according to the different participles, generates the text to be rewritten The corresponding several candidate official documents and correspondences of case.

Word segmentation processing, shape are carried out to the content of text of the official documents and correspondence to be rewritten got according to above-mentioned steps S102~S108 At a number of participle, then go to rewrite participle using at least one specified term of domain knowledge base, and then to difference It, will be corresponding to automatically generate official documents and correspondence to be rewritten according to the obtained different content of text of the different participles of rewriting after participle is rewritten Several candidate's official documents and correspondences, since domain knowledge base is pre-established according to the content of text of corpus, which includes official documents and correspondence necks The corresponding term of a large amount of entity mobility models in domain, and entity mobility models are knowing in entity of the official documents and correspondence fields with specific meanings Know, specified content of text of the term from corpus, candidate official documents and correspondence obtained in this way, not only substantial amounts, but also official documents and correspondence Word content also will be more rich and varied, meet official documents and correspondence well and need with novelty, diversity and can follow current The demand of hot spot, in order to when these abundant in content colorful official documents and correspondences are promoted marketing to user, it is easier to be attracted to user Note that being conducive to improve user's clicking rate and conversion ratio.

For ease of understanding, here to show that small rated throws the marketing of pension fund by the corset advertisement position of APP in mobile phone For official documents and correspondence, it is illustrated.

As shown in fig. 7, the official documents and correspondence update method can comprise the following steps that

Step S302, the content of text of official documents and correspondence to be updated is obtained.

Step S304, word segmentation processing is carried out to the content of text, obtains several participles.

Step S306, term pair is specified according at least one of domain knowledge base of the official documents and correspondence fields to be updated The participle is rewritten.

Step S308, the revised content of text is carried out according to the different participles, generates the text to be updated The corresponding several candidate official documents and correspondences of case.

Step S310, it is given a mark based on language model to the candidate official documents and correspondence.

Wherein, language model be used for determine sentence probability model, wherein the probability of sentence be represented by P (W1, W2 ..., Wk), W1, W2 ..., Wk be sentence in each word segment.

Pass through language model in this way, so that it may determine the possibility degree that each word segment occurs in official documents and correspondence, and occur When in official documents and correspondence sentence, the whole clear and coherent degree of sentence, and then according to the clear and coherent degree of sentence, so that it may determine entire candidate official documents and correspondence Clear and coherent degree.

Specifically, can each candidate official documents and correspondence be input in language model, is counted using speech model to sentence probability It calculates, and using sentence probability as marking result.In this way, score is higher, a possibility that indicating the sentence physical presence bigger, the time Selection case more meets the expression of natural language, that is to say, that sentence score is higher, and the fluency of sentence is higher, and grammer is also got over Correctly, the candidate official documents and correspondence that such sentence is constituted, quality are also higher.

Step S312, the candidate official documents and correspondence after marking is pressed into preset more new strategy, updates the official documents and correspondence to be updated.

In specific implementation, more new strategy can be preset according to actual needs, for example more new strategy may include that the frequency updates Strategy, candidate official documents and correspondence Selection Strategy.

In specific implementation, one or several candidate official documents and correspondences outputs of marking higher (i.e. quality is higher) can be used for conduct Update the alternative official documents and correspondence of official documents and correspondence.It specifically, can be according to marking as a result, choosing the higher candidate official documents and correspondence of rewriting of marking as final Arithmetic result, according to marking as a result, press S*=ar gmax_i∈[1,T]S_i, determine each candidate official documents and correspondence S_iPut in order, with Convenient for selecting alternative official documents and correspondence according to more new strategy.

It should be noted that the official documents and correspondence Improvement in the content and previous embodiment of above-mentioned steps S302~S308 Step S102~S108 content it is close, which is not described herein again.

S302~S312 through the above steps passes through language model, it may be determined that is each generated out by statement sequence The sentence probability of candidate's marketing official documents and correspondence, and then according to the probability, it gives a mark to candidate official documents and correspondence, such score is bigger, indicates the marketing Official documents and correspondence more meets natural language expressing, and quality is also higher, and then goes to update using the higher official documents and correspondence of quality, it is easier to be attracted to use Family note that be conducive to improve user clicking rate and conversion ratio.

In this specification embodiment, n-gram language model is can be used in language model, and neural network language mould can also be used Type (NNLM), and then be trained using the text data in corpus.

In some embodiments, as shown in figure 8, following steps can be used in language model is trained:

Step S402, text data is obtained from corpus.

In specific implementation, corpus can be only with general corpus, since the text data of general corpus is by big Data are crawled and are collected into, and the language message for including is richer, thus established using the text data of general corpus and More accuracy, is predicted the marking result for obtaining candidate official documents and correspondence by the language model that training obtains.

Step S404, word segmentation processing is carried out to the text data.

Here word segmentation processing can refer to preceding description, and which is not described herein again.

Step S406, the first identifier is added to the participle.

By the first identifier, to obtain term (lexical item) sequence of every text, in order to go to instruct according to term sequence Practice language model.

Step S408, the participle that the first identifier is added is used for train language model.

According to above-mentioned steps S402~S408, by adding in participle using a large amount of text data in general corpus Enter the first identifier, to obtain each term sequence, and these term sequence train language models is utilized, due to general corpus The text data in library is that acquisition is crawled by big data, and not only these text datas more meet the expression of natural-sounding, but also Data are also richer, to will be preferably applied to the score of predicting candidate official documents and correspondence after language model is trained based on these data.

For ease of understanding, principle explanation is carried out to application of the official documents and correspondence update method in marketing official documents and correspondence below.

As shown in figure 9, constructing domain knowledge base by step S1~S3 first, and trained by step S4~S6 Language model can thus complete the rewriting and update of marketing official documents and correspondence by step S7~S11.

Specifically, step S1~S11 is briefly described as follows:
