Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to attached
During figure, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary is implemented
Embodiment described in example does not represent all embodiments consistent with the application.On the contrary, they be only with such as
The example of the consistent apparatus and method of some aspects be described in detail in appended claims, the application.
For comprehensive understanding the application, numerous concrete details are refer in the following detailed description, but art technology
Personnel are it should be understood that the application can be realized without these details.In other embodiments, public affairs are not described in detail
Method, process, component and the circuit known, are obscured in order to avoid undesirably resulting in embodiment.
Fig. 1 is a kind of schematic flow sheet of Email screening technique shown in the exemplary embodiment of the application one, such as Fig. 1
Shown, methods described includes：
Second title of step S101, the first title of the selected mail of acquisition first, and the second selected mail.
Wherein, user first selects therein two when being intended to screen the Email (abbreviation mail) that title is repeated
Mail is sealed, then the Email screening plant of post-processing system obtains the title of two envelope mails of user's selection, respectively
For the second title of the first title of the first selected mail, and the second selected mail.
Step S102, compares first title and second title, judges that the first intersection accounts for first title
Or whether the ratio of second title is more than or equal to default threshold value, first intersection is first title
The part overlapped between second title.
After first title and second title is got, judge that the first intersection accounts for first title or institute
Whether the ratio for stating the second title is more than or equal to default threshold value, that is, has judged whether there is coincidence between the two simultaneously
Part and intersection whether meet account for the first title ratio be more than or equal to default threshold value condition, or overlap
Whether part, which meets, accounts for condition of the ratio of the second title more than or equal to default threshold value.Wherein, the first coincidence part is judged
The ratio for dividing the ratio for occupying the first title still to occupy the second title can be made with sets itself with the longer title of length
The judgement of ratio is occupied for the first intersection, the degree of accuracy of judgement can be improved, is preferably mode.
In one embodiment, step S102, can include：
Step a1, relatively first title and second title length；
Step a2, if the length of first title is more than or equal to the length of second title, described first is marked
Topic as referring to title, will second title title as a comparison, if the length of second title is more than described the
The length of one title, using second title as referring to title, by first title title as a comparison.
For the contrast of the first title and the second title, which can also be randomly assigned to refer to title, then another is
Contrast title.But when the mode of contrast is word for word to contrast a title with another title, for the mark word for word decomposed
Topic length (i.e. character number) shorter can be improved to specific efficiency, it is therefore preferred to using the shorter title of length as by
The title that word is decomposed, that is, contrast title, while the longer title of another length is as referring to title.Two titles
During equal length, one conduct of any of which can be selected to refer to title, in the present embodiment, two length for heading phases
Deng when, with the first entitled reference title, this is a kind of embodiment, not limit must be with the first entitled reference
Title.
It is longer to refer to title with length after the length of the first title and the second title is compared, length it is shorter for pair
Than title, that is, if the length of first title is more than or equal to the length of second title, by described first
Title is as referring to title, by second title title as a comparison, if the length of second title be more than it is described
The length of first title, using second title as referring to title, by first title title as a comparison.
Step a3, j-th of character by i-th of character of the contrast title successively with the reference title is compared,
Judge whether j-th of character of i-th of character for contrasting title and the reference title be identical, wherein, j=k (i-1)
To k (i), k (i-1) is the sequence number in the reference title at first with the i-th -1 character identical character of the contrast title,
K (i) is the sequence number in the reference title at first with i-th of character identical character of the contrast title, and k (i-1) is less than
K (i), k (i) are less than or equal to the character length m of the reference title, and the kth (i) for recording k (i) and the reference title is individual
Character Ck(i)；
Step a4, judges whether i is less than or equal to n-1, wherein, n is the character length for contrasting title；
Step a5, if i is less than or equal to n-1, calculates i=i+1, and return to step a3, otherwise, performs step a6.
Wherein, i=1,2 ... n, and during i=1, k (0)=1.For contrast title, each character for contrasting title is pressed
Contrasted with reference to the character sequence (i.e. conventional string characters put in order) of title with referring to title, judge that it is
It is no identical with reference to some character in title.The first character of title will be contrasted by the character sequence pair with reference to title
Than when, if take turns to some character with reference to title, the current character contrasted is identical with the character in contrast title,
Complete of contrast need not then be continued and refer to title, the character is with reference to the first character in title at first with the contrast title
Identical character is accorded with, can now be recorded with reference to title and the current character identical character contrasted in contrast title,
And record sequence number (subscript of such as character string dimension) of the character in reference to title.Because title is to connect in itself
Continuous character string, the part that one title is overlapped with another title can not be unordered discrete.When the first of contrast title
Individual character with reference to title some character it is identical when, with reference to title this character be exactly second of contrast bebinning character,
When namely second character of contrast title with reference to title with being contrasted from being contrasted with reference to title for second
Beginning character starts, similarly, when second character for contrasting title is identical with some character with reference to title, with reference to title
This character be exactly third time contrast bebinning character, that is, contrast title second character with reference to title carry out
During contrast since the bebinning character for being used for third time contrast with reference to title, by that analogy.
Above-mentioned execution logic can be expressed as following procedure step：For i=1,2 ... n, by the of the contrast title
J-th character of the i character successively with the reference title is compared, judge the contrast title i-th character and
Whether j-th of character of the reference title identical, wherein, j=k (i-1) to ki, k (i-1) be the reference title at first
With it is described contrast title the i-th -1 character identical character sequence number, k (i) be the reference title at first with it is described right
Than the sequence number of i-th of character identical character of title, k (i-1) is less than k (i), and k (i) is less than or equal to the reference title
Character length m, record k (i) and the reference the title individual character C of kth (i)k(i)。
Specifically, will j-th of character progress of the 1st character that title be contrasted successively with the reference title
Compare, judge whether j-th of character of the 1st character for contrasting title and the reference title be identical, contrasted
Cheng Zhong, kth (1) character with reference to title is identical with the 1st character for contrasting title, then wheel contrast is so far, its
In, j=k (0) to k (1), k (0)=1, k (1) is less than or equal to the character length m of the reference title, then records k (1)
And the individual character C of kth (1) of the reference titlek(1)；Then judge whether i is less than or equal to n-1, wherein, n is described
The character length of title is contrasted, judges whether 1 be less than or equal to n-1 herein, illustrate n=10, that is, judges whether 1 is small
In equal to 9, undoubtedly this wheel 1 is less than 9；Then order calculates i=i+1, then i=2, and return to step a3, that is, by institute
State j-th character of the 2nd character of contrast title successively with the reference title to be compared, judge the contrast mark
Whether the 2nd character of topic and j-th of character of the reference title are identical, in comparison process, with reference to the kth (2) of title
Character is identical with the 2nd character for contrasting title, then wheel contrast is so far, wherein, j=k (1) to k (2), k (2)
Less than or equal to the character length m of the reference title, kth (2) individual character of k (2) and the reference title is then recorded
Ck(1)；By that analogy.In above-mentioned steps, if i is more than n-1, illustrate that each character for contrasting title has all been contrasted
Finish, thus turn to step a6 and carry out subsequent step.
In said procedure step, it is possible to which when the character for contrasting title has not been contrasted also, k (i) has equalized to ginseng
Examine the character length m of title, then when next round is contrasted, by since with reference to title last character,
But in this case with reference to also by can be identical with the character in contrast title without character, therefore having no effect on execution in title
Logic.
Step a6, judges Ck(i)Between whether there is adjacent character；
Step a7, if Ck(i)Between whether there is adjacent character, calculate Ck(i)Between adjacent character account for described first
Whether the ratio of title or second title is more than default threshold value.
Wherein, for the C of all recordsk(i), judge Ck(i)Between whether there is adjacent character, if it is not, than
To title with being discrete character with reference to title identical character, it is impossible to be used as intersection.If there is adjacent character,
These adjacent characters are then calculated into the number of adjacent character as the first intersection, the number divided by first are marked
The length of topic, or divided by the second title length, obtain the ratio that the first intersection accounts for the first title or the second title.
Wherein, be calculated with the length of the length of the first title also the second title ratio can with sets itself, both all can, with
The longer title of length is conducive to improving the degree of accuracy to calculate, thus can according to step a1 result, come select length compared with
Long title calculates ratio.Ck(i)Between, it is possible that one section of character is adjacent, but it is not phase with another section of adjacent character
Adjacent, that is, it is possible that the adjacent character of multistage, then every section of adjacent character all be look at into one first coincidence
Part, calculates ratio, and the ratio of each calculating is judged to each first intersection.
Step S103, if first intersection accounts for first title or the ratio of second title is more than or waited
In default threshold value, the mail to be selected that title includes first intersection is searched in mail to be found；
Step S104, selected state is set to by the mail to be selected.
Wherein, if the first intersection accounts for the ratio of first title or second title more than or equal to default
Threshold value, then can determine the corresponding mail of two titles to repeat mail.It is segmentation weight between first title and the second title
Close, as long as there is first intersection to account for the ratio of first title or second title more than or equal to default
Threshold value, you can determine the corresponding mail of two titles (the first selected mail and the second selected mail) to repeat mail.So
It is more than or equal to the first intersection of default threshold value according to the ratio for accounting for first title or second title afterwards,
Title is searched in mail to be found and includes the mail to be selected of first intersection, wherein, the mail to be found can be with
It is to be checked for whole mails, or unread mail (unread mail is denoted as new mail in some mail box systems)
When looking for mail for whole mails, the lookup for repeating mail is not limited only to unread mail or new mail, and this mode is conducive to
Mail is repeated to history to operate.The lookup can use the conventional method that mail is searched by title.Find
Title includes the mail to be selected of first intersection, is the mail repeated with the first selected mail and the second selected mail.
Then the mail found is set to selected state.If the first intersection accounts for first title or second mark
The ratio of topic is less than default threshold value, it is determined that the corresponding mail of two titles is not to repeat mail, can terminate to perform
Journey, can also show the prompting of the two non-duplicate mails of envelope mail, facilitate user to re-start selection.
In addition, for step S102, its execution logic can also use gradation segment lookup formula to contrast, it is specially：First from
A conduct is randomly assigned in first title or the second title and refers to title, another title, or as walked as a comparison
Rapid a1 is the same, compares the length of two titles, then chooses the shorter title as a comparison of wherein length, another is used as ginseng
Examine title；Then in first time contrasts, searched whether in reference to title in the presence of overall contrast title, the lookup
Conventional String Searching Algorithm can be used, if it is present performing length and ginseng that step S103 judges contrast title
Whether the ratio for examining title is more than or equal to default threshold value, if it is, determining that the first title and the second title are corresponding
Mail is repeats mail, if it is not, then the corresponding mail of two titles is not to repeat mail；If do not deposited with reference in title
In overall contrast title, then contrast title is segmented according to default length, the default length is by default
Threshold value determines that the character length that is segmented into headed by the first character for contrasting title is preset length interception contrast title
The first segmentation is obtained, is that preset length interception contrast title obtains the by character length headed by second character for contrasting title
Two-section, by that analogy, obtains t segmentation, then searches whether there is the first segmentation in reference to title, if deposited
Then illustrating that the first intersection of the first title and the second title is equal to default threshold value, and may not necessarily be further continued for
Search whether there is other segmentations, if it does not exist, then searching whether there is the second segmentation in reference to title, with such
Push away, as long as with reference to any one existed in title in t segmentation, you can determine the first of the first title and the second title
Intersection is equal to default threshold value, so that it is determined that the corresponding mail of two titles is repetition mail, its first intersection
It is segmented with reference to present in title.Above-mentioned implementation compares step a1 to step a7 mode, although step is compared
Less, but the degree of accuracy is relatively low, for the angle for improving accuracy rate, step a1 to step a7 is preferably mode.
