Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings, but the present invention is not limited thereto.
Fig. 1 shows a schematic flow chart of an author and mailbox correspondence method according to an embodiment of the present invention. As shown in FIG. 1, according to one embodiment of the present invention, a mailbox is first located in a file found to include works of known authors, step 101. The files including the works of the known authors are, for example, word files, web pages, PDF files, etc., and these files include some information such as captions, footnotes, etc. in addition to the text of the works of the known authors, and these information usually include information of the authors, such as names, work units, brief descriptions, etc., and of course, may also include information of their contact ways, such as mailboxes.
The known author may be an author known in advance to obtain a mailbox thereof, or an author obtained in a retrieval result obtained by retrieving a specific theme file or the like, and now needs to obtain a mailbox thereof.
There are various methods for extracting mailbox addresses from files, for example, for a word file, a search function provided by the word itself may be used, for a txt file, Easy Email extra software, a FileEmail extra for a PDF file, etc. may be used, and some simple JAVA programs may be provided to implement this function. Persons skilled in the art who have the benefit of this disclosure may use any now known or future known method to extract mailbox addresses from a file, and will not be described in detail herein. When a plurality of mailboxes are found, the subsequent steps can be carried out one by one, or the subsequent steps can be carried out every time one mailbox is found.
Next, in step 102, the number of files in which the known author and the mailbox co-occur, that is, the amount of co-occurrence of the author and the mailbox, is counted in the files including the works of the known author.
Then, in step 103, the collaborators of the known author in the file where the known author and the mailbox co-occur are obtained. For example, assuming that a known author is Zhao big and has 100 files containing his work, in case of looking for his mailbox, the mailbox finish 2017@163.com was found in step 101 and a total of 95 files containing the author Zhao big work were found containing this mailbox. Of these 95 pieces, there may be 50 pieces that are done individually by Zhao and 45 pieces that are done in cooperation with a human. The collaborators (collaborators) are searched for file by file, for example, the collaborators who collaborate with Zhao Da, such as Qian's two, Zhang's three, Li's four, Zhou Wu's five, Wu Lu, Zheng Qi, Wang Jiu, Cheng Shi, etc. (purely for the purpose of facilitating understanding of the present invention, no actual collaborating work is suggested or explained), etc., can be formed into a list or stored in a database, and are operated one by one for the collaborators in subsequent operations.
Then, in step 104, the number of co-occurrences of each collaborator and the mailbox in the file containing the works of the known collaborators, namely the co-occurrence amount of the collaborators and the mailbox, is counted. That is, the number of co-occurrences of each collaborator with the mailbox is found in 100 documents containing known works of the author Zhao and Da. For example, the possible result is that qian di and the mailbox finish 2017@163.com co-occur 10 times, 4 times for zhang, 6 times for lie, 3 times for friday, 7 times for wu luo, 5 times for zheng qi, 5 times for wangjiu, and 5 times for cheng shi.
The difference between the author and mailbox co-occurrence and the collaborator and mailbox co-occurrence is then determined at step 105. Assuming that the threshold is 80% of the co-occurrence of the author and mailbox, i.e. 95 x 80% — 76 times, the difference between the co-occurrence of the author and mailbox and the co-occurrence of the collaborator and mailbox is greater than the threshold for each collaborator, and thus in step 106, mailbox fineart2017@163.com is associated with the known author zhao. In one embodiment, the threshold may be set to 1, i.e., the mailbox and the known author may be associated as long as all other authors have a lower co-occurrence with the mailbox than the collaborator. If the difference is less than zero, i.e., a number of co-occurrences of a collaborator with the mailbox is greater than a number of co-occurrences of the known author with the mailbox, the mailbox may be deemed not to be associated with the known author and operations for the next mailbox may begin.
On the other hand, according to an embodiment of the present invention, if in step 104, the number of co-occurrences of a partner with the mailbox finish 2017@163.com is large, for example, the number of co-occurrences of two and the mailbox finish 2017@163.com is 80, then in step 105, it is determined that the difference between the co-occurrence amount of the partner and the mailbox and the co-occurrence amount of the partner and the mailbox is less than the threshold, which indicates that the occurrence of the mailbox may be due to the co-occurrence of two and may be influenced by other factors, and although the number is still less than 95 times of co-occurrence amount of the partner and mailbox, the mailbox should not be directly associated with the known partner. At this time, in step 107, the co-occurrence rate of the author and the mailbox is counted, that is, the ratio of the file co-occurring between the known author and the mailbox in the file containing the work of the known author, that is, the co-occurrence rate of the author and the mailbox is counted. For example, in the above example, the file containing the known work by the author Zhao is 100 pieces, of which 95 pieces appear the mailbox finish 2017@163.com, with an occurrence rate of 95%. Then, in step 108, the co-occurrence rate of each collaborator and the mailbox is counted, that is, the ratio of the file co-occurring between each collaborator and the mailbox in the file containing the work of each collaborator, that is, the co-occurrence rate of the collaborator and the mailbox is counted. In this step, the file to be retrieved is not limited to the file containing the work of the known author, but only the file containing the work of each collaborator. In this step, according to one embodiment, the file including the known author and the collaborative works of the collaborators may be deleted from the file containing the works of the collaborators. For example, when the co-occurrence rate of the second money and the mailbox finish 2017@163.com is counted, the file containing the cooperative work of the second money and the Zhao-da is excluded. For example, the statistical results may be two 1% of money, three 0% of Zhang, etc. The difference between the author and mailbox co-occurrence and the collaborator and mailbox co-occurrence is then calculated at step 109. If the author and mailbox co-occurrence rates differ significantly (above a predetermined threshold) from each of the collaborators and mailboxes, then an author is associated with a mailbox in step 106.
On the other hand, according to an embodiment of the present invention, if there is a case where the difference is not significant, for example, the case where the co-occurrence rate of lie four and the mailbox reaches 94%, and the difference between the occurrence rates is lower than a threshold (for example, 15%), it indicates that the mailbox may be affected by some factors, such as a reference to a file, and the like, and it is not desirable to directly associate the mailbox with the known author. At this time, in step 110, a distance between the mailbox address and the known author and a distance between the mailbox address and the collaborator in a file including the collaborative works of the known author and the collaborator are calculated. In the above example, that is, in a file of a collaborative work including known author Zhao Da and associate Li four, the distance of the mailbox address fineart2017@163.com from the Zhao Da name and the distance of the mailbox address fineart2017@163.com from the name of Li four are determined. There are various methods for calculating such a distance, such as a file layout method, a layout block of a file is obtained, a distance between two letters in the same block is shorter than a distance between two letters in different blocks, and the number of characters between two letters is calculated as a distance for the same block, and the like. Those skilled in the art may take various methods known now or in the future to calculate these distances. Then, in step 111, a probability that the distance between the mailbox address and the known author is less than the distance between the mailbox address and the collaborator is determined. For example, if zhao da and li ji collaborate on 10 pieces of works, and the distance between the mailbox and zhao da is smaller than the distance between the mailbox and li ji for 9 pieces of documents, it can be determined that the probability that the distance between the mailbox address and the known author zhao da is smaller than the distance between the mailbox address and the collaborator li ji is 90%. Associating the mailbox with the known author in step 106 when the probability that the distance between the mailbox address and the known author is less than the distance between the mailbox address and the collaborator is greater than a predetermined threshold (e.g., 70%).
Fig. 2 shows a schematic block diagram of a mailbox and author corresponding apparatus according to an embodiment of the present invention. The description of the block diagram can be used to explain the method of the present invention, and the foregoing description of the method can also be used to understand the mailbox and author corresponding apparatus of the present invention.
As shown in fig. 2, according to an embodiment of the present invention, first, the mailbox search unit 201 searches for a mailbox in the searched file including the works of known authors. Next, the author and mailbox co-occurrence amount counting unit 202 counts the number of files in which a known author and a mailbox co-occur, that is, the author and mailbox co-occurrence amount, among files including works of the known author. Then, the partner acquiring unit 203 acquires the partner of the known author in the file where the known author and the mailbox co-occur. Next, the partner and mailbox co-occurrence amount counting unit 204 counts the number of co-occurrences of each partner and the mailbox, that is, the partner and mailbox co-occurrence amount, in the file containing the works of known authors. The number difference judgment unit 205 determines the difference between the author and mailbox co-occurrence amount and the collaborator and mailbox co-occurrence amount. Mailbox association unit 206 associates the known author with a mailbox when the difference is greater than a threshold. If the difference is less than zero, i.e., a number of co-occurrences of a collaborator with the mailbox is greater than a number of co-occurrences of the known author with the mailbox, the mailbox may be deemed not to be associated with the known author and operations for the next mailbox may begin.
On the other hand, according to an embodiment of the present invention, if the difference between the co-occurrence amount of the author and the mailbox determined by the number difference determination unit 205 and the co-occurrence amount of the author and the mailbox is less than the threshold, this indicates that the mailbox should not be directly associated with the known author. At this time, the author and mailbox co-occurrence rate counting unit 207 counts the author and mailbox co-occurrence rate, that is, the percentage of the file in which the known author and the mailbox co-occurrence rate in the file containing the work of the known author are counted, that is, the author and mailbox co-occurrence rate. At the same time or later, the partner and mailbox co-occurrence rate statistic unit 208 counts the partner and mailbox co-occurrence rate, that is, the rate of the file in which each partner and mailbox co-occur in the file containing the work of each partner, that is, the partner and mailbox co-occurrence rate. The file to be retrieved is not limited to a file containing the works of the known authors, but only a file containing the works of the respective collaborators. According to one embodiment, a file including the known author and the collaborative work of each of the collaborators may be deleted from a file containing the work of each of the collaborators. The ratio difference calculation unit 209 then calculates the difference between the author and mailbox co-occurrence rate and the collaborator and mailbox co-occurrence rate. If the co-occurrence rate of the author and the mailbox is greater than the co-occurrence rate of each of the collaborators and the mailbox (higher than a predetermined threshold), the mailbox associating unit 206 associates the author with the mailbox.
On the other hand, if there is the worse case, it indicates that the mailbox may be affected by some factor, such as a reference to a file, etc., it is not desirable to directly associate the mailbox with the known author. At this time, the distance calculating unit 210 calculates the distance between the mailbox address and the known author and the distance between the mailbox address and the collaborator in the file including the collaborative works of the known author and the collaborator. There are various methods for calculating such a distance, such as a file layout method, a layout block of a file is obtained, a distance between two letters in the same block is shorter than a distance between two letters in different blocks, and the number of characters between two letters or a combination of letters is calculated as a distance for the same block, and the like. Those skilled in the art may take various methods known now or in the future to calculate these distances. Then, the distance probability determination unit 211 determines the probability that the distance between the mailbox address and the known author is smaller than the distance between the mailbox address and the collaborator. For example, if zhao da and li ji collaborate on 10 pieces of works, and the distance between the mailbox and zhao da is smaller than the distance between the mailbox and li ji for 9 pieces of documents, it can be determined that the probability that the distance between the mailbox address and the known author zhao da is smaller than the distance between the mailbox address and the collaborator li ji is 90%. When the probability that the distance between the mailbox address and the known author is smaller than the distance between the mailbox address and the collaborator is larger than a predetermined threshold (e.g., 70%), a mailbox associating unit associates the mailbox with the known author.
The present invention can be realized in the form of software, which, when running or after being compiled, can make a processor with processing functions, such as a computer CPU, a field programmable gate array, a chip, a single chip, etc., realize the above functions, method steps, etc., and the software can be stored in a readable storage medium, such as a memory, a hard disk, an optical disk, a magnetic disk, etc.
The above detailed description of the invention is merely to give the person skilled in the art further insight into implementing preferred aspects of the invention, and does not limit the scope of the invention. Only the claims are presented to determine the scope of the invention. Therefore, combinations of features and steps in the foregoing detailed description are not necessary to practice the invention in the broadest sense, and are instead taught merely to particularly detailed representative examples of the invention. Furthermore, the various features of the teachings presented in this specification may be combined in various ways, which, however, are not specifically exemplified, in order to obtain additional useful embodiments of the present invention.
