Abstract: Disclosed is a contents information search control system that, when automatic search of contents, such as game software, is performed with a terminal, such as a cellular phone, according to a user's preference, can reflect a change in user's interest or expansion of a target range of an interest. A change in user's interest is quantitatively grasped as an interest vector, and when the interest vector satisfies a predetermined condition, a search condition is updated to reflect the change in the user's interest in a search condition. In addition, expansion of a target range of the user's interest is quantitatively grasped as distance information, and when the distance information satisfies a predetermined condition, the search condition is updated to reflect the expansion of the target range of the user's interest in the search condition. The interest vector or the distance information is calculated from an automatic search result on the basis of contents selected by a user, and updated as occasion demands.

Abstract: A cellular phone of a member, who newly joins a group, creates a member list including a group ID and profile of a leader, and transmits a participation contact mail including a profile of the corresponding new member to a cellular phone of the leader. The cellular phone of the leader adds the profile of the new member to a member list after receiving the participation contact mail. The participation contact mail is transferred to the cellular phones of other existing members registered in the member list. The cellular phones of the existing members add the profile of the new member to their member lists in response to the received contact mail and transmit their profiles to the cellular phone of the new member. The cellular phone of the new member adds the profiles of the existing members to the member list in response to the received participation contact mail.

A change in user's interest is quantitatively grasped as an interest vector, and when the interest vector satisfies a predetermined condition, a search condition is updated to reflect the change in the user's interest in a search condition. In addition, expansion of a target range of the user’s interest is quantitatively grasped as distance information, and when the distance information satisfies a predetermined condition, the search condition is updated to reflect the expansion of the target range of the user's interest in the search condition. The interest vector or the distance information is calculated from an automatic search result on the basis of contents selected by a user, and updated as occasion demands.

Abstract: A player can easily select a desired game, and the information about players can be appropriately managed and provided. A user terminal transmits self-introduction information to a room master. The room master adds the self-introduction information from the user terminal to the player table list. Additionally, the self-introduction information is added to update history data, and a count value of the update history counter is incremented. The user terminal adds the current count value of the update history counter and ask the room master for an update history. Upon receipt of the update history requests from multiple user terminals, the room master transmits data to all user terminal members (addressed to the IRC channel) in the room. The data is transmitted sequentially from the update history data associated with the oldest update counter value in the requests to the update history data associated with the latest history counter value of the room master.

Abstract: An item for use in a game can be easily and appropriately dealt. When an item to be purchased is selected from an auction item list on the screen of the user terminal, and when a bid price which can be paid for the item is determined, the current bid price (old bid price) of the highest bidder is read. The read old bid price is compared with the new bid price, and it is determined whether the new bid price is the highest. If it is the highest price, then the player save data is read, and it is determined whether there is enough money to pay the bid price. If there is enough money to pay the bid price, the amount corresponding to the bid price is subtracted from the player save data.
