TECHNICAL FIELD OF THE INVENTION
The present invention relates to an information sharing server and an information sharing program for sharing information by electronic mail.
[0002]
[Prior art]
2. Description of the Related Art In recent years, knowledge database technology for linking information sharing to corporate management has been receiving attention. However, the conventional knowledge database requires the user to input in a predetermined format, so the user is troublesome to input and tends to avoid the input, and after all, data input is often performed. There is no present.
[0003]
In order to avoid this problem, a system that does not require the user to input data in a specific format is required. In other words, if the user can input information from a task that the user performs on a daily basis without requiring the user to input a special format, data can be efficiently stored.
[0004]
With the development of network technology in recent years, users frequently use e-mail even in business or private use. Therefore, it has become known that if the contents of an e-mail are stored and organized, it is possible to construct an effective knowledge database based on information obtained by the user. A typical example is disclosed in JP-A-2002-44124. If the user's e-mail is sequentially recorded and stored in this manner, it is possible to extract various information from information included in the e-mail later.

[0006]
[Problems to be solved by the invention]
The invention disclosed in the above publication realizes browsing and recording of e-mail among a plurality of users by providing an e-mail server (e-mail management system) different from the e-mail server.
[0007]
When using ordinary e-mail software, records of e-mail transmission / reception remain only at the user terminal used by each user, and the e-mail is forwarded in order to view it from other user terminals Extra work such as having you do it will occur. In order to avoid this, the invention disclosed in this publication discloses a configuration in which an electronic mail management system stores an electronic mail record in addition to an electronic mail server.
[0008]
However, in the case of the system configuration as described above, another new e-mail server (e-mail management system) is added to the existing e-mail server, so that the e-mail server is multiplexed. Therefore, system management becomes complicated and complicated. Further, there is a problem that it is actually necessary to remodel the e-mail server in order to construct this multiplex configuration.
[0009]
Further, in the invention disclosed in the above publication, all e-mails of the user pass through the e-mail management system. Therefore, if any trouble such as system down occurs in the e-mail management system, However, there is also a problem that the user cannot send and receive the e-mail itself. Furthermore, since all e-mails are stored in the e-mail management system, all e-mails that you do not want to share or that contain contents that are difficult to view if viewed by a third party, such as trade secrets, are all shared. Will be.
[0010]
In addition, in the invention disclosed in the above publication, the classification of electronic mails by category is merely a filtering process, and information is not automatically extracted from transmission and reception of electronic mails.
[0011]
[Means for Solving the Problems]
In view of the above problems, the present inventor has invented an information sharing server that can share information by e-mail without modifying the existing e-mail server. That is, as a first solution, an e-mail account unique to the information sharing server for sharing the information described in the e-mail is created in the e-mail server. The above problems were solved by specifying the e-mail account of the shared server. In the present invention, the information sharing server is handled as the same line as the user terminal, and it is not necessary to add any changes to the e-mail server. In addition, since e-mail is not transmitted / received via the information sharing server, even if some trouble occurs in the information sharing server, if the e-mail server is operating normally, the user terminal is not used. Has no effect on sending and receiving e-mail.

[0012]
As a second solution, instead of creating an e-mail account unique to the information sharing server, an e-mail account of a specific user may be assigned to the information sharing server. For example, if the email account of the user A is “a@xxx.com”, “a@xxx.com” is also assigned to the information sharing server as the email account. As a result, the electronic mail server transmits all the electronic mails addressed to the user A to the information sharing server, so that the electronic mail can be shared. When the user A transmits an e-mail from the user terminal and desires to share the e-mail, the user A adds his or her own e-mail address “a@xxx.com” to the original destination. Is automatically transmitted to the information sharing server, so that the information can be shared.
