Then, the time event status information generation unit 100a generates time event status information about the display start time of the document information (S103). Then, the utterance status information generation unit 100d collects the voice around the user terminal 14 (S104). Then, the person situation information generation unit 100c identifies a person associated with the value of the situation detail information of the person situation information (S105). In the process shown in S105, for example, a server that detects a person recorded in a call record or e-mail transmission / reception record, and associates and manages the user name and the current location of the user terminal 14 used by the user. Inquiries are made. The processes shown in S104 and S105 are continued until the display of the document information by the display control unit 98 is completed (S106: N).

  When the display of the document information by the display control unit 98 is completed (S106: Y), the person situation information generation unit 100c ends the identification of the person (S107), and the utterance situation information generation unit 100d receives the voice. The collection of is terminated (S108). Then, the time event status information generation unit 100a generates time event status information for the display end time of the document information (S109). Then, the utterance status information generation unit 100d generates utterance status information based on the voice collected in the process shown in S104 (S110). Then, the time event status information generation unit 100a generates time event status information about the weather and news specified based on the display start time and display end time of the document information (S111). Here, for example, the time event status information indicating the current information in the period from the given time before the display start time of the document information to the time after the given time of the display end time of the document information is generated. Then, the person situation information generation unit 100c generates person situation information about the person specified in the process shown in S105 (S112). Then, the status information transmission unit 102 transmits the various status information generated as described above to the document information search device 12 (S113), and the processing shown in this processing example is terminated.

  In addition, this invention is not limited to the above-mentioned embodiment.

  For example, the situation information registration unit 78 may associate the authority information with the received situation information and store it in the situation information storage unit 62. The authority information indicates an identifier of a user who is permitted or prohibited from using the associated status information. Then, the search process execution unit 70 executes a search process for the situation information that is determined to be usable by the user of the user terminal 14 that is the transmission source of the search condition based on the associated authority information. May be. Specifically, for example, authority information indicating that only the user of the user terminal 14 that is the transmission source of the situation information can be used may be associated with the situation information. In this way, for example, the user of the user terminal 14 can search the document information using the situation information corresponding to the situation when the user browses the document information.

  Further, the division of roles between the document information search device 12 and the user terminal 14 is not limited to the above. For example, it is assumed that the status information receiving unit 76 of the document information search device 12 has received location status information whose status detailed information values are “Chiba Prefecture”, “Tokyo”, and “Kanagawa Prefecture”, respectively. In this case, the situation information registration unit 78 may generate place situation information including “Kanto region” as the value of the situation detailed information, and store it in the situation information storage unit 62.
