In addition, the technical solution without carrying out additional mark to text, belongs to unsupervised algorithm, thus save a large amount of mark at
This.
The generation method of text snippet provided by the above embodiment described in detail below.
Multiple sentences in target text are obtained first.In the step, can according to specified punctuation mark to target text into
Row is split, to obtain multiple sentences.For example, specified punctuation mark include fullstop "." and branch ";", then, utilize target text
In this punctuation mark "." and ";" target text is split after, can be obtained multiple sentences.
After getting multiple sentences in target text, can be predicted according to preset subject classification mode each sentence with
The first tightness between designated key.Wherein, subject classification mode may include topic model or subject classification rule.Specified master
Topic can be theme involved by the content of text of any target text, such as designated key is that sport, cuisines etc. are all kinds of
Theme.
Topic model is the statistical model clustered in a manner of unsupervised learning to the implicit semantic structure of collected works,
Semantic analysis and text mining can be carried out to each sentence in text, such as text is collected, classify and is dropped by theme
Dimension etc..
In one embodiment, it can be predicted between each sentence and designated key using existing any topic model
First tightness.For example, designated key is sport, then can analyze each sentence when using topic model analysis target text
In include the information arbitrarily relevant to sport such as basketball, swimming, running, body-building, and then these information predictions by analyzing
The first tightness between each sentence and designated key out.Wherein, the frequency for occurring word relevant to sport in sentence is higher, should
The first tightness between sentence and designated key is also higher.
In another embodiment, the between sentence and designated key is predicted using preset subject classification rule
One tightness.Subject classification rule may include such as under type:
Firstly, determining the corresponding descriptor of designated key.
Wherein, descriptor may include keyword relevant to designated key.For example, designated key is sport, then descriptor
It may include keyword " sport ", " movement " etc..Descriptor can be set according to the actual demand of user, such as, if it is desired to it is raw
At text snippet relevant to " sport " this major class, then can set descriptor includes " sport " and " movement ";If wanting to generate
Be related to the text snippet of all related subjects of " sport ", then can set the descriptor more refined, such as may include " sport ",
" basketball ", " shuttlecock " and " swimming " etc..
Secondly, analyzing sentence, to determine the number of the related term comprising descriptor and/or descriptor in sentence
Mesh.
Wherein, the related term of descriptor may include the near synonym of descriptor.For example, descriptor is " cuisines ", then to sentence
When being analyzed, word similar in a kind of meaning such as " cuisines " that include in sentence, " food " can be excavated.
Again, according to the number for the related term in sentence including descriptor and/or descriptor, sentence and designated key are predicted
Between the first tightness;Wherein, the number and the first tightness of the related term in sentence comprising descriptor and/or descriptor it
Between be positively correlated.That is, the number of the related term in sentence comprising descriptor and/or descriptor is more, the sentence and designated key it
Between the first tightness it is higher.
Then the similarity between each sentence is determined.In one embodiment, existing any similarity operator can be used
Method calculates the similarity between each sentence.For example, between each sentence Levenshtein distance (i.e. string encoding away from
From) as the similarity between each sentence.
After determining the similarity between each sentence, the first tightness predicted is modified using assignment algorithm.
In one embodiment, assignment algorithm is Pagerank algorithm.It, can be close to first in the following way based on this
Degree is corrected at least once:
Firstly, being created between each node using each sentence as a node according to the similarity between each sentence
Relational network figure.
In the step, when creating relational network figure, it can be determined the need for establishing according to the similarity between each sentence each
Side between sentence node.Specifically, determining the two sentences pair when the similarity between two sentences reaches preset threshold
There are a lines between two nodes answered, and then according to the side between each sentence node, can create between each sentence node
Relational network figure.
Fig. 2 shows the relational network figures between each sentence node in a specific embodiment.As shown in Fig. 2, relational network
It include tri- sentence nodes of A, B, C in figure, wherein due to the similarity between sentence A and sentence B, between sentence A and sentence C
Reach preset threshold, therefore there are a line, sentence node A and sentence sections between corresponding sentence node A and sentence node B
There is also a lines between point C;Since the similarity between sentence B and sentence C is not up to preset threshold, corresponding sentence
Side is not present between node B and sentence node C.
Secondly, determining that each first tightness is the corresponding initial weight of each sentence.
Again, according to relational network figure, iteration at least once is carried out to initial weight using Pagerank algorithm, is obtained each
The corresponding final weight of sentence.
In the step, the mode that initial weight is multiplied with Iterative Matrix can be used and be iterated, such as following equation (1),
In, A is Iterative Matrix, PnThe weight obtained for nth iteration.It is preset until the difference between the corresponding weight of each sentence is less than
When threshold value, iteration can be stopped, the weight obtained at this time is the corresponding final weight of each sentence.
Pn+1=APn (1)
The corresponding final weight of each sentence, the second tightness between as each sentence and designated key.
After obtaining the second tightness between each sentence and designated key, can according to the second tightness to each sentence into
Row processing, to obtain the text snippet relevant to designated key of target text.
In one embodiment, each sentence can be ranked up and is spliced according to the sequence of the second tightness from big to small
Processing, obtains orderly text;Then determine that the orderly text is the text snippet relevant to designated key of target text.
In one embodiment, corresponding first sentence of the second tightness for reaching the second preset threshold can be first filtered out,
Then the sequence according to corresponding second tightness of each first sentence from big to small, is ranked up each first sentence and stitching portion
Reason, to obtain the text snippet relevant to designated key of target text.
In the present embodiment, the corresponding sentence of the second tightness of certain threshold value is reached by filtering out, and to these sentences
It is ranked up, splices, the tightness of the text snippet obtained and designated key can be made higher.
