Abstract: In a client, an input receiver receives utterance data inputted through the client and utterance data inputted through a different client and received by a receiver, and then stores the utterance data in a past log storage as a past log. When the input receiver receives new utterance data, a reference information generator determines preceding utterance data referred to by the new utterance data, from the past log, generates reference information indicating a reference relationship, and then stores the reference information in a reference information storage. Then, a transmitter transmits the new utterance data and the reference information to the different client, and a display controller displays the utterance data stored as the past log, the new utterance data, and an indicator based on the reference information.

Abstract: By applying a privacy policy, which describes and manages a policy for disclosure of preference information, to the preference information, it is determined whether or not to disclose some or all of the information to a third party based on classification as a result of matching by a matching system. The description of a privacy policy makes it possible to achieve a meaningful communication by disclosing preference information to others within a detailed range while keeping the preference information undisclosed if the user does not wish disclosure thereof, such as disclosing only preference information including preferences matching those of the other user or disclosing only preference information including preferences shared in a certain user group.

Abstract: A method and system are provided for automating scheduling of a plurality of resources. Initially, the resources that are potential candidates for scheduling are selected, and a time interval for scheduling the selected resources is submitted. Scheduling results are determined by automatically concatenating the availability of the resources based upon the submitted time interval. The scheduling results are presented to a user with the presentation of the results illustrating the availability of the selected resources.
