Description of the drawings
Illustrate the embodiment of the present invention or technical solution of the prior art in order to clearer, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it is clear that, the accompanying drawings in the following description is only this
Some embodiments of invention, for those of ordinary skill in the art, without creative efforts, can be with
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is a kind of method flow diagram of information processing of the present invention.
Specific embodiment
Below in conjunction with the attached drawing in the present invention, the technical solution in the embodiment of the present invention is carried out it is clear, completely retouch
It states, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, all other reality that those skilled in the art is obtained under the premise of creative work is not made
Example is applied, belongs to protection scope of the present invention.
The method of a kind of information processing of the embodiment of the present invention, as shown in Figure 1, including the following steps：
Step S01, extracts the coordinate of all words in document files, and according to all words of coordinate pair of each word into
Row branch；
Step S02, removal time format content, space and colon obtain the grapholect of every row from the word of every row；
Step S03 calculates the gap between adjacent character in often capable grapholect, and according to gap to the standard of every row
Word is grouped；
According to character types each in the grapholect of every row, cutting processing is carried out to the grapholect of every row by step S04
To obtain row cutting result；
Step S05 summarizes the row cutting result of every row output.
Specifically, cutting processing includes：When grapholect includes Chinese and English, according to the gap between character and
Character local width is split Chinese word language with English word.
Specifically, cutting processing is specially：When whether inter-character space two neighboring in grapholect is in the first prepsetting gap
During with the second prepsetting gap, whether the overlapping range for judging two neighboring character is more than that predetermined word is wide；If so, two neighboring word
Symbol belongs to same；If not, cutting is carried out to two neighboring character.When in grapholect character there are during lateral overlap, when
When inter-character space is between half word is wide with zero, illustrate former and later two characters there are lateral overlap, and overlapping range does not surpass
The wide half of word is crossed, thinks that front and rear character belongs to one piece at this time, does not do cutting；If overlapping range is more than the wide half of word,
Carry out cutting.
Specifically, cutting processing is specially：When the difference in height of two neighboring character is more than preset height ratio, to adjacent
Two characters carry out cutting, processing character cause situation not of uniform size；The difference in height of former and later two characters is more than 20%, then it is assumed that no
Belong to one text block, carry out cutting.
Specifically, cutting processing is specially：When character is located among bracket in grapholect, then two neighboring character is judged
Belong to same.
Such as in processes when English mixes situation, " DR diagnosis reports list ", in this text, " D " and " R " and " R "
Gap between " examining " is simultaneously unequal, but because DR, which is English character and distance, is less than the 10% of local width, then recognizes
To belong to a word, so the word judges the clearance condition between " diagnosis report list " below, hair as a whole
Now their gap is all identical, so this kind of situation is not done and is divided.
Such as during processing lateral overlap situation, when -0.5 word is wide<gap<When 0 (gap represents the inter-character space of adjacent character),
Former and later two characters are represented there are lateral overlap, and overlapping range is no more than the wide half of word, such case thinks front and rear character
One piece is belonged to, does not do cutting, such as overlapping is more than half, then carries out cutting.
When handling other situations, when the number of words in line of text be no more than 2, then do not do cutting.
Specifically, branch is specially：For there is overlapping up and down or hang the row at angle, it is classified as same a line.
Specifically, removal time format content, space and colon obtain the grapholect of every row from the word of every row
Before step, further include with preset regular expression time format contents extraction comes out in the word of every row the step for.
Specifically, for there is overlapping up and down or hang the row at angle, it is classified as same a line.
Specifically, the contents extraction of time format in file is come out with default regular expression.
Such as：The default regular expression of extraction time is as follows：
'(20\d\d-\d{1,2}-\d{1,2}.*:\d\d:D d) ' #2017-03-05 forms；
u'：(\d\d-\d{1,2}-\d{1,2}.*:\d\d:D d) ' # date collecteds：16-08-16 12:02 form；
U'(20 d d d { 1,2 } moons d { 1,2 } .*:\d\d:D d) ' #2017 forms on March 4, match pattern
In containing Chinese, use unicode encode；
'(20\d\d/\d{1,2}/\d{1,2}.*:\d\d:D d) ' #2017/02/27 forms；
'(\d{1,2}/\d{1,2}/20\d\d.*:\d\d:D d) ' #27/02/2017 forms；
'(20\d{6}\d\d:\d\d:\d{0,2})'#20160329 08:10 forms；
Wherein, it is regular expression before #, is associated annotation after #.
As unit of character, branch's processing is carried out with the corresponding coordinate of character for a kind of method of information processing of the present invention,
It is grouped after grapholect is obtained by calculating the gap between word, row cutting processing.This kind of method removes field value from
Cumbersome configuration during cutting realizes zero configuration cutting, is adapted to various text layouts so that structuring extraction process become it is simple,
It is adaptable.
The present invention is further described by specific embodiment above, it should be understood that, here specifically
Description, should not be construed as the restriction to the spirit and scope of the invention, and one of ordinary skilled in the art is reading this explanation
The various modifications made after book to above-described embodiment belong to the range that the present invention is protected.
