(Operation)
Hereinafter, the operation of the candidate network presentation system according to the embodiment of the present invention will be described with reference to the drawings.

  First, the user operates the terminal device 4 to access a mail server (not shown) and send and receive mail. Also, the activity phase history 30 is updated by accessing the activity phase history management server according to the progress of the activity item.

  Further, when the user wants to know an expert who corresponds to the ongoing activity item, the user operates the terminal device 4 to operate the personal network candidate presentation server 1. The human network candidate presentation server 1 operates as described below when a presentation request is received.

  FIG. 7 is a flowchart showing an operation example of the candidate connection presentation server according to the embodiment of the present invention.

  First, the feature word extraction unit 10A acquires (case ID, phase) of an activity item currently being executed by the user from the activity phase history 30 and substitutes it into the set Z (S1). When the set Z is not an empty set, that is, when there is an active matter being executed by the user (S2; No), an arbitrary (case ID, phase) is extracted from the set Z and substituted into X (S3). When there is no activity item being executed by the user (S2; Yes), the operation is terminated.

  Next, the user's mail message related to X (case ID, phase) is acquired from the mail history 20 to extract feature words, and a set A is created (S4). Note that a method for extracting feature words from a mail message is performed using, for example, a TF / IDF method described below.

は、頻出する単語について値が大きくなる。また、単語ｔ_ｉを含むメールの数をＭ（ｔ_ｉ）とし、全メール数をＭとすると、

は、めずらしい単語について値が大きくなる。以上より、

は、特徴的に頻出する単語について値が大きくなるため、ＴＦＩＤＦ（ｔ_ｉ）が大きくなる単語ｔ_ｉを特徴語とする。 First, if the appearance frequency of the word t _i is F (t _i ),

Increases for frequently occurring words. Also, if the number of emails containing the word t _i is M (t _i ) and the total number of emails is M,

Increases the value for rare words. From the above,

Since the value of a characteristically frequent word increases, the word t _i having a large TFIDF (t _i ) is used as a characteristic word.

  Next, a set B is created using the feature words of (case ID, phase) of the completed activity case from the feature word extraction result 11B extracted in the past (S5), and a set B similar to the set A, that is, being executed The phase of the activity item having the feature word similar to the feature word extracted from the phase of the activity item is extracted, the similarity r is calculated, and the set K is created (S6). The method of calculating the similarity r is performed by the method described below.

である。ただし、Ｐ（ｔ）は、特徴語ｔが特徴語抽出結果１１Ｂのエントリーに出現する確率であり、単語ｔを含むエントリーの出現頻度をＥ（ｔ）とすると、

である。なおｒは、Ｒ（Ａ，Ｂ）から求められた値である。 For feature word sets A and B, R (A, B) is the similarity between the two.

It is. However, P (t) is a probability that the feature word t appears in the entry of the feature word extraction result 11B, and the appearance frequency of the entry including the word t is E (t).

It is. R is a value obtained from R (A, B).

  Next, when the set K is not an empty set, that is, when there is a phase of a similar activity item (S7; No), an arbitrary item (item ID, phase, r) is extracted from the set K and substituted for Y (S8). ). When there is no phase of a similar activity item (S7; Yes), another item (item ID, phase) is extracted from the set Z, and steps S3 to S6 are repeated.

  When the Y phase is after the X phase, that is, when the Y phase is a phase that occurs in the future than the running phase (S9; Yes), the phase arrival required to reach the Y phase from the running phase is reached. Time t is calculated (S10). If the Y phase is before the X phase (S9; No), the (project ID, phase, r) is ignored and the process returns to step S7.

  The user set of Y is regarded as an expert, and is stored as the candidate connection result 11C together with the phase arrival time t and the similarity r (S11), and steps S7 to S11 are repeated.

  Next, the display means 10C displays the candidate connection extraction result 11C as shown in FIGS. 6A to 6C. These displays are displayed on a display unit (not shown) provided in the terminal device 4.

[Other embodiments]
The present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the step S9 in FIG. 7, the future phase (project ID, phase, r) is extracted from the phase being executed. However, the past phase may be extracted and used for behavior analysis or the like.

  In addition, the feature word extraction unit 10A, the personal network candidate extraction unit 10B, and the display unit 10C used in the above embodiment may be read from a storage medium such as a CD-ROM into a storage unit in the apparatus, the Internet, or the like. You may download to the memory | storage part in an apparatus from the server apparatus etc. which are connected to this network. Moreover, you may implement | achieve part or all of the means used by the said embodiment by hardware, such as ASIC.
