Description
Technical field
The data structured process field of unstructured data in terms of the invention belongs to big data research, be related to it is a kind of by
It is related to the pdf document cutting method of stock right transfer theme.
Background technology
Unstructured data is included to be converted to user with file existing for WORD, EXCEL, PDF, TXT, audio, video
It is friendly, be used directly for statistical analysis and the structural data of application includes the data that are stored in the form of SQL or ORCAL
Etc. the difficult point for being the more urgent demand of current big data application field and research.
There are some achievements in the data structured method of the current file for the shorter PDF format of length, in document
The main thought of existing method is converted to for this completely unstructured existing data first by source PDF document → with XML
Or WORD forms have the file of this semi-structured data, by canonical method → be ultimately converted to SQL or ORCAL shapes
The data of structuring existing for formula；And there is conversion efficiency in both idea and methods when XML or WORD text lengths are larger
It is relatively low, conversion error rate it is higher the deficiencies of.
The content of the invention
The shortcomings that it is an object of the invention to overcome above-mentioned prior art, there is provided a kind of by being related to stock right transfer theme
Pdf document cutting method, this method can efficiently, accurately realize the pdf document cutting for being related to stock right transfer theme.
To reach above-mentioned purpose, it is of the present invention by the pdf document cutting method for being related to stock right transfer theme include with
Lower step：
1) service scripts stored with PDF format is obtained by distributed interconnection crawler technology；
2) carry out being related to stock right transfer according to the service scripts with PDF format storage that operation layer demand obtains step 1)
The business layer analysis of theme, it is determined that being related to the language Expressive Features of the pdf document of stock right transfer theme, keyword and keyword mark
Topic；
3) the PDF texts for being related to stock right transfer theme are determined by the pdf document and step 2) that are related to stock right transfer theme
The language Expressive Features of part carry out keyword to source pdf document page by page and the canonical of keyword title is searched for, it is determined that including key
The page number information set P of the pdf document of word and keyword title；
4) the abnormal page number in the pdf document page number information set P obtained to step 3) using page number exception removal mechanisms at work
It is removed, the pdf document page number information set P after must removingfinal；
5) pdf document page number information set P after the removal obtained according to step 4)finalTo source pdf document carry out on
The cutting of stock right transfer theme, complete the pdf document cutting for being related to stock right transfer theme.
Set SRT={ SRT including keyword and keyword title1,SRT2,SRT3,SRT4,SRT5, wherein, SRT1Table
Show counterparty, SRT2Represent counterpart, SRT3Represent to transfer the possession of the total number of share of stock of equity, SRT4Represent to transfer the possession of equity shareholding equity, SRT5Table
Show exchange hour.
The page number value information collection for being related to the pdf document of stock right transfer theme is combined intoP1={ include SRT1's
The page number value set of pdf document }；P2={ include SRT2Pdf document page number value set；P3={ include SRT3PDF text
The page number value set of part }；P4={ include SRT4Pdf document page number value set；P5={ include SRT5Pdf document page
Code value set }.
Step 4) concrete operations are：The pdf document page number information collection obtained using page number exception removal mechanisms at work to step 3)
The abnormal page number closed in P is removed, the pdf document page number information set P after must removingfinal；
When in pdf document page number information set P the page number value corresponding with second element of page number value corresponding to the first element it
Difference is more than pthreshold, i.e., | p2-p1|>pthresholdWhen, then remove the first element in pdf document page number information set P and correspond to the page number
Value；When the page number value corresponding with element second from the bottom of page number value corresponding to element last in pdf document page number information set P
Difference be more than pthreshold, i.e., | pm-pm-1|>pthresholdWhen, then remove element last in pdf document page number information set P
Corresponding page number value, the pdf document page number information set P after must removingfinal。
The invention has the advantages that：
It is of the present invention by the pdf document cutting method for being related to stock right transfer theme in concrete operations, first obtain with
The service scripts of PDF format storage, then determine to be related to the language Expressive Features of the pdf document of stock right transfer theme, keyword and
Keyword title, it is then determined that the pdf document page number information set P comprising keyword and keyword title, while to improve PDF
File page number information aggregate P accuracy and reliability, realize and pdf document page number information set P is about simplified, the present invention passes through
The abnormal page number in the pdf document page number information set P that page number exception removal mechanisms at work obtains to step 3) is removed, Ran Houzai
The pdf document for completing to be related to stock right transfer theme according to pdf document page number information set P after removal is cut, so as to effectively carry
The precision and reliability of height cutting, have universality and stronger application foundation.

Embodiment one
With reference to figure 1, according to the business layer analysis of the pdf document to being related to stock right transfer theme, it is determined that being related to stock right transfer
Pdf document language Expressive Features, keyword and keyword title, be related to the keyword of the pdf document of stock right transfer theme
And keyword title is defined as counterparty, " counterpart, transfers the possession of total number, transfers the possession of shareholding equity and exchange hour；It is crucial using this
Word and keyword title find the page number information set of the source pdf document where keyword and keyword title using regularity conditions
P, it is corresponding to be combined into P with counterparty page number collection1={ 15,22,25 }, it is corresponding to be combined into P with counterpart page number collection2=
{ 22,23,28 }, the corresponding page number collection with transferring the possession of total number are combined into P3={ 25,28,31 }, it is corresponding with transferring the possession of shareholding equity
Page number collection is combined into P4={ 25,31 }, it is corresponding to be combined into P with exchange hour page number collection6={ 15,28,31,45 }, then be related to equity
The page number collection for transferring the possession of the source PDF document of theme is combined into P={ 15,22,25,28,31,45 }；According to page number exception removal mechanisms at work, then
What is formed is related in the page number value set P of the source pdf document of stock right transfer theme, the first element page corresponding with second element
Code is respectively 15 and 22, and the difference of its page number value is more than given threshold value pthreshold=3, then give up to fall in page number information set P
One element corresponds to page number value 15, then the page number collection for being now related to the source pdf document of stock right transfer theme be combined into 22,25,28,
31,45 }, and in page number information set P the element second from the bottom page number corresponding with element last is respectively 31 and 45, its page number
The difference of value is more than given threshold value pthreshold, then give up to fall element page number value 45 last in page number information set P, now
The page number collection for being related to the source pdf document of stock right transfer theme is combined into Pfinal={ 22,25,28,31 }；According to this page number set
Theme cutting is carried out to source pdf document, that is, cuts page 22, page 25, page 28 and page 31 in the pdf document of source, stamps
Watermark, form the pdf document of the design stock right transfer theme of new cutting.
