Abstract: A data search system 1 conducts a search through a plurality of pieces of search target data to which at least date and time information is attached as attached data. The data search system includes search means for searching the plurality of pieces of search target data for keyword-matching data including a search keyword, and extracting, as a linked search keyword, the date and time information on a time period that is included in the attached data attached to the keyword-matching data, linked search means for searching the plurality of pieces of search target data for whether there exists linked matching data to which attached data including a time period that is close to the time period of the linked search keyword is attached, and output means for outputting the keyword-matching data and the linked matching data.

Abstract: A content evaluation apparatus and a content evaluation method that can distribute contents that a user potentially needs without any omissions. A history class separation unit generates a separation plane for separating in a separation plane a characteristic vector of a selected content and characteristic vectors of non-selected contents stored in a browsing history table. A user characteristic vector calculation unit generates a user characteristic vector based on an orthogonal vector perpendicular to the separation plane thus generated and stores the user characteristic vector in a user characteristic vector management table. Subsequently, when a recommendation request receiving unit receives a recommendation request, a content evaluation unit evaluates the contents based on the stored user characteristic vector.

Abstract: A service recommendation system and a service recommendation method capable of improving the probability of the estimation of a user task and recommending a service depending on a user task can be provided. The user role obtaining unit 210 of the service recommendation server 100 obtains the role of a user, and the task estimating unit 207 estimates a user task from a task model associated with the obtained user role and stored in the task knowledge DB 103. The service knowledge retrieving unit 208 retrieves a service capable of assisting a user task obtained from the task estimating unit 207.

Abstract: A recommendation information generation apparatus and a recommendation information generation method that can select a similar user appropriately even if the amount of history information is small. In an information distribution server, a user characteristic vector calculation unit calculates a user characteristic vector of each of users, and a similar user calculation unit calculates the degree of similarity between the users based on the calculated user characteristic vector of each of the users. The similar user calculation unit then selects a similar user who is similar to a first user based on the calculated degree of similarity. A relevance evaluation unit generates recommendation information for the first user based on the characteristic vector of the selected similar user.

Abstract: Providing an information providing system and an information providing method capable of providing detail information required for a user to execute his/her scheduled activity smoothly.

Abstract: The present invention provides a task selection assistance apparatus, and a task selection assistance method, which enable burdens on a user to be alleviated in selecting a task for solving a problem. A domain candidate determining portion 210 determines domain candidates to be presented to the user from among domains stored in a task model DB 102, and a domain candidate transmitting portion 201 transmits the domain candidates to a portable terminal 101. A user selected domain obtaining portion 203 obtains a domain, which has been selected by the user, from the portable terminal 101, and the task candidate determining portion 211 determines task candidates to be presented to the user from among tasks stored in the task model DB 102 based on the domain selected by the user.

Abstract: A search server 14 comprises a plurality of search target databases 24, 26 each storing search target information and task IDs to indicate classifications according to the search target information in correspondence to each other; a user action database 22 storing searching information and task IDs in correspondence to each other; a query receiver 20 for receiving a query containing a query character string from a mobile communication terminal 12; a user action determiner 23 for specifying a task ID associated with the query, with reference to the query character string and the information stored in the user action database 22; a facility selector 25 and a Web content selector 28 for acquiring the search target information corresponding to the specified task ID from the plurality of search target databases 24, 26; and a search result information generator 30 for generating search result information to the query from the acquired search target information.

Abstract: The invention provides an information delivery apparatus and information delivery method that can improve the rate of access by a user. A task node designation unit acquires task information related to contents sent by a contents transmission unit, and the contents transmission unit sends the acquired task information to the user, thereby making it possible to assist the actions of the user suitably. Consequently, since task information that is related to the contents, for example, task information which can cause the user to consider performing an action of some kind in relation to the content can be also viewed, the user is encouraged to perform new actions, whereby the access rate to the content can be improved.

Abstract: In the mobile telephone 1 relating to the present invention, a control section 2 performs control for switching between a non-active state which refuses inputs to an application program, and a rest state in which the application program is temporarily halted. The control section 2 performs control for switching the execution state of the application program from the non-active state to the rest state, in accordance with instructions from an input section 3. The control section 2 further performs control for switching the execution state of the application program from the non-active state to the rest state, in accordance with a function contained in an application program.

Abstract: A mobile telephone 2 having a function for downloading and executing an application A from a network server comprises a communications module execution control system 1. The judging section 132 acquires and refers to an attribute information file 14. If the attribute information file 14 contains a (UseTelephone=call) definition, then the judging section 132 judges that the call section 102 is to be executed by the application A, and if there is no UseTelephone key, then it judges that the call section 102 is not be executed by the application A. If the UseTelephone value is not “call”, then the judging section 132 judges that the download of the application A is not allowed. The control section 136 controls the download and execution of the application A, in accordance with the judgement from the judging section 132.
