Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but it will be appreciated by those skilled in the art that the present application may be practiced without these specific details. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the embodiments.
Fig. 1 is a schematic flowchart illustrating an email screening method according to an exemplary embodiment of the present application, where as shown in fig. 1, the method includes:
step S101, a first title of a first selected mail and a second title of a second selected mail are obtained.
When a user wants to screen e-mails with repeated titles (e-mails for short), two of the e-mails are selected first, and then the e-mail screening device of the mail processing system acquires the titles of the two e-mails selected by the user, which are the first title of the first selected e-mail and the second title of the second selected e-mail respectively.
Step S102, comparing the first title with the second title, and determining whether a ratio of a first overlapping portion to the first title or the second title is greater than or equal to a preset threshold, where the first overlapping portion is an overlapping portion between the first title and the second title.
After the first title and the second title are obtained, whether the proportion of the first overlapped part in the first title or the second title is greater than or equal to a preset threshold value or not is judged, that is, whether the overlapped part exists between the first title and the second title and whether the proportion of the overlapped part in the first title is greater than or equal to the preset threshold value or not is judged, or whether the proportion of the overlapped part in the second title is greater than or equal to the preset threshold value or not is judged. The ratio of the first overlapped part occupying the first title or the ratio of the first overlapped part occupying the second title can be set by self, and the title with longer length is used for judging the occupation ratio of the first overlapped part, so that the judgment accuracy can be improved, and the method is a better mode.
In one embodiment, step S102 may include:
a step a1 of comparing the lengths of the first title and the second title;
step a2, if the length of the first title is greater than or equal to the length of the second title, using the first title as a reference title and the second title as a comparison title, and if the length of the second title is greater than the length of the first title, using the second title as a reference title and the first title as a comparison title.
For the comparison of the first title and the second title, it is also possible to randomly designate which one is the reference title and then the other is the comparison title. However, when the comparison is made by comparing one title with another title word by word, the shorter length (i.e., the number of characters) of the title used for word by word decomposition improves the comparison efficiency, and therefore, it is preferable that the title with the shorter length is used as the title for word by word decomposition, that is, the comparison title, and the other title with the longer length is used as the reference title. When the lengths of the two titles are equal, any one of the two titles may be selected as a reference title, and in this embodiment, when the lengths of the two titles are equal, the first title is taken as the reference title.
After comparing the lengths of the first title and the second title, the longer title is used as a reference title, and the shorter title is used as a comparison title, that is, if the length of the first title is greater than or equal to the length of the second title, the first title is used as the reference title, the second title is used as the comparison title, and if the length of the second title is greater than the length of the first title, the second title is used as the reference title, and the first title is used as the comparison title.
Step a3, comparing the ith character of the comparison title with the jth character of the reference title in sequence, and determining whether the ith character of the comparison title is the same as the jth character of the reference title, wherein j is k (i-1) to k (i), k (i-1) is the serial number of the character in the reference title which is the first character same as the ith character of the comparison title, k (i-1) is less than k (i), and k (i) is less than k (i)Or equal to the length m of the reference header, record k (i) and the k (i) th character C of the reference headerk(i)；
Step a4, judging whether i is less than or equal to n-1, wherein n is the character length of the comparison title;
step a5, if i is less than or equal to n-1, calculate i ═ i +1 and return to step a3, otherwise, execute step a 6.
Where i is 1, 2 … … n, and when i is 1, k (0) is 1. For the comparison title, each character of the comparison title is compared with the reference title according to the character sequence (namely the conventional character string character arrangement sequence) of the reference title, and whether the character is the same as a certain character in the reference title is judged. When the first character of the comparison title is compared according to the character sequence of the reference title, if the character currently compared in the comparison title is the same as the character when a certain character of the reference title is reached, the comparison of the whole reference title does not need to be continued, the character, namely the character which is the first character in the reference title and is the same as the first character of the comparison title, at this time, the character which is the same as the character currently compared in the comparison title is recorded, and the serial number (such as the subscript of the character string array) of the character in the reference title is recorded. This is because the titles themselves are continuous character strings, and the portions of one title that overlap another title cannot be scattered out of order. Similarly, when the second character of the comparison title is the same as the certain character of the reference title, the character of the reference title is the starting character of the third comparison, that is, the second character of the comparison title is compared with the reference title, starting from the starting character of the reference title for the third comparison, and so on.
The above-described execution logic may be expressed as the following program steps: for i-1, 2 … … n, the ith character of the comparison title is sequentially added to the reference titleIs compared with the jth character of the reference title, and whether the ith character of the reference title and the jth character of the reference title are the same or not is judged, wherein j is k (i-1) to ki, k (i-1) is the sequence number of the character which is firstly the same as the ith character of the reference title, k (i-1) is less than k (i), k (i) is less than or equal to the character length m of the reference title, and the k (i) and the kth (i) character C of the reference title are recordedk(i)。
Specifically, the 1 st character of the comparison title is sequentially compared with the jth character of the reference title, whether the 1 st character of the comparison title is the same as the jth character of the reference title is judged, if the kth character (1) of the reference title is the same as the 1 st character of the comparison title during comparison, the comparison is carried out until the pair is compared, wherein j is k (0) to k (1), k (0) is 1, and k (1) is less than or equal to the character length m of the reference title, and then the kth character (1) of the reference title and the kth character (1) C of the reference title are recordedk(1)(ii) a Then, judging whether i is less than or equal to n-1, wherein n is the character length of the comparison title, and here, judging whether 1 is less than or equal to n-1, for example, n is 10, namely judging whether 1 is less than or equal to 9, and undoubtedly, the round 1 is less than 9; then let i be i +1, then i be 2, and return to step a3, that is, compare the 2 nd character of the comparison title with the j th character of the reference title in turn, determine whether the 2 nd character of the comparison title is the same as the j th character of the reference title, and compare the k (2) th character of the reference title with the 2 nd character of the comparison title in the comparison process, where j is k (1) to k (2), k (2) is less than or equal to the character length m of the reference title, and then record k (2) and the k (2) th character C of the reference titlek(1)(ii) a And so on. In the above step, if i is greater than n-1, it indicates that each character of the comparison title has been compared, so the process goes to step a6 to perform the following steps.
In the above procedure steps, it is possible that when the characters of the comparison title have not been compared, k (i) is already equal to the character length m of the reference title, then in the next comparison, starting from the last character of the reference title, but in this case, none of the characters in the reference title will be the same as the characters in the comparison title, and therefore the execution logic will not be affected.
Step a6, judgment Ck(i)Whether there is an adjacent character in between;
step a7, if Ck(i)Whether there is an adjacent character between them, calculate Ck(i)Whether the proportion of adjacent characters in the first title or the second title is larger than a preset threshold value or not.
Wherein for all recorded Ck(i)Judgment of Ck(i)If there is no adjacent character, the character with the same comparison title and the reference title is a discrete character and cannot be used as a superposition part. If the adjacent characters exist, the adjacent characters are used as a first overlapped part, the number of the adjacent characters is calculated, and the number is divided by the length of the first title or the length of the second title to obtain the proportion of the first overlapped part in the first title or the second title. The calculation ratio of the length of the first title and the length of the second title may be set by itself, and both of them may be calculated by the title with a longer length, which is beneficial to improving the accuracy, so that the calculation ratio of the title with a longer length may be selected according to the result of step a 1. Ck(i)In between, a character adjacent to another but not adjacent to another character may occur, that is, a plurality of adjacent characters may occur, each adjacent character is viewed at a first overlapping portion, a ratio is calculated for each first overlapping portion, and each calculated ratio is determined.
Step S103, if the proportion of the first overlapped part in the first title or the second title is larger than or equal to a preset threshold value, searching a mail to be selected of which the title comprises the first overlapped part in the mail to be searched;
and step S104, setting the mail to be selected as a selected state.
If the proportion of the first overlapped part in the first title or the second title is greater than or equal to a preset threshold value, determining that the mails corresponding to the two titles are repeated mails. The first title and the second title are overlapped in a segmented mode, and as long as the proportion of a first overlapped part in the first title or the second title is larger than or equal to a preset threshold value, the mails (the first selected mail and the second selected mail) corresponding to the two titles can be determined to be the repeated mails. And then searching a mail to be selected with a title containing a first overlapped part in the mail to be searched according to the first overlapped part accounting for the first title or the second title, wherein the mail to be searched can be all mails or unread mails (some unread mails in an electronic mailbox system are marked as new mails), and when the mail to be searched is all mails, the searching of repeated mails is not limited to the unread mails or the new mails, which is favorable for operating historical repeated mails. The search may use a conventional method of searching for mail by title. The searched title comprises the mail to be selected of the first overlapped part, namely, the mail which is overlapped with the first selected mail and the second selected mail. And then setting the searched mail as the selected state. If the proportion of the first overlapped part in the first title or the second title is smaller than the preset threshold value, determining that the mails corresponding to the two titles are not the repeated mails, ending the execution process, and displaying a prompt of the two mails which are not the repeated mails, so that the user can conveniently select again.
In addition, for step S102, the execution logic may also use fractional segmentation search formula comparison, specifically: randomly assigning one of the first title and the second title as a reference title and the other as a comparison title, or comparing the lengths of the two titles as in step a1, and then selecting the shorter one as the comparison title and the other as the reference title; then in the first comparison, whether an integral comparison title exists in the reference title is searched, the search can use a conventional character string search algorithm, if yes, step S103 is executed to judge whether the ratio of the length of the comparison title to the reference title is larger than or equal to a preset threshold value, if yes, the mails corresponding to the first title and the second title are determined to be repeated mails, and if not, the mails corresponding to the two titles are not repeated mails; if no integral comparison title exists in the reference title, segmenting the comparison title according to a preset length, wherein the preset length is determined by a preset threshold value, the segmentation is to take the first character of the comparison title as a first character length to obtain a first segment, take the second character of the comparison title as a second character length to obtain a second segment, and so on to obtain t segments, then searching whether the first segment exists in the reference title, if so, indicating that the first overlapped part of the first title and the second title is equal to the preset threshold value, and no other segments exist in the reference title, if not, searching whether the second segment exists in the reference title, and so on, as long as any one of the t segments exists in the reference title, it can be determined that the first overlapped part of the first header and the second header is equal to the preset threshold value, so as to determine that the mails corresponding to the two headers are repeated mails, and the first overlapped part is the segment existing in the reference header. The above implementation has fewer steps than the implementation of step a1 to step a7, but has lower accuracy, and from the viewpoint of improving accuracy, the implementation of step a1 to step a7 is the better implementation.
After the email system sets the found email to be in the selected state, the repeated emails are displayed as checked in the mailbox interface. The e-mail system can also display an operation dialog box for the selected repeated mails, inquire whether the user performs operations of deleting, marking as read, marking as unread or moving to other folders on the mails, and count the selected repeated mails, such as counting the number of the repeated mails, and display the counting result for the user to refer.
According to the technical scheme provided by the embodiment, whether the e-mail is the repeated e-mail or not is automatically judged according to the two e-mails selected by the user, if the e-mail is the repeated e-mail, other repeated e-mails are found out according to the overlapped part and are set to be in the selected state, so that the user does not need to manually select each repeated e-mail, and the e-mail processing efficiency is improved.

step b3, comparing the ith character of the comparison title with the jth character of the reference title in sequence, and determining whether the ith character of the comparison title is the same as the jth character of the reference title, wherein j is k (i-1) to k (i), k (i-1) is the serial number of the character which is the first character of the reference title and is the same as the ith-1 character of the comparison title, and k (i) is the serial number of the character which is the first character of the reference title and is the same as the jth character of the reference titleThe sequence number of the character in the reference title which is the first character same as the ith character of the comparison title, k (i-1) is less than k (i), k (i) is less than or equal to the character length m of the reference title, k (i) and the kth (i) character C of the reference title are recordedk(i)；
B4, judging whether i is less than or equal to n-1, wherein n is the character length of the comparison title;
step b5, if i is less than or equal to n-1, calculating i ═ i +1, and returning to step a3, otherwise, executing step b 6;
step b6, judge Ck(i)Whether there is an adjacent character in between;
step b7, if Ck(i)Whether there is an adjacent character between them, calculate Ck(i)The adjacent characters account for the proportion of the first title, and whether the proportion is larger than a preset threshold value is judged;
where i is 1, 2 … … n, and when i is 1, k (0) is 1.
