Abstract: According to one embodiment, an electronic apparatus including group specifying module configured to specify a cluster group including clusters in content being played back, an access module configured to access a collection of arbitrary cluster groups relevant to the cluster group specified by the group specification module, a search module configured to searching for content specified by a cluster group included in the collection accessed by the access module, and a content presentation module configured to present a result of search by the search module.

Abstract: According to one embodiment of the present disclosure, a first data file, a second data file, a third data file and a file controlling logic portion are provided. In the first data file, basic data of a plurality of programs are stored. The basic data indicates a plurality of attributes related to each program. The second data file associates viewers with a plurality of programs. The third data file associates programs with a plurality of viewers. The file controlling logic portion is configured to access the first to third data files, generate a cluster in which data is associated depending on a theme and specify a viewer and/or a program included in the cluster.

Abstract: A message exchange unit receives and distributes a message in a community in which a plurality of users participates. A message memory stores the message received by the message exchange unit. An extraction rule memory stores an extraction rule applicable for the message. The extraction rule includes an extraction pattern, an extraction target and a display format. An information extraction unit extracts information from the message stored in the message memory by referring to the extraction rule. An extraction result memory stores extraction result information by the information extraction unit. An extraction result editing unit edits the extraction result information stored in the extraction result memory. A message generation unit generates another message representing editing of the extraction result information.

Abstract: A content management system for managing contents including at least one of a video image and an audio, which are received from a network or a broadcast including a wired or wireless connection and are stored in a storage device for storing the received contents in association with content information, includes a human relationship table which records information relating to a plurality of entries utilizing the content management system, an entry searching section which searches one of entries as a query destination of an evaluation relevant to designated contents stored in the storage device, using the human relationship table, a content evaluation information acquisition section which acquires evaluation information from the query destination with respect to the designated contents, and a content reduction section which determines a method of reducing the designated contents based on the evaluation information.

Abstract: An answer support system includes an extracting unit to extract sentences of question made by a questioner, asking back of an answerer to the question, a reply of the questioner to the asking back, and an answer made by the answerer from a plurality of messages exchanged between the questioner and the answerer based on a reply relationship between the messages, a paragraph structure and sentence representation of each message, and a storing unit to store the extracted sentences in association with each other. In response to a new question, plural sets of sentences of question, asking back, reply, and answer stored in the past are searched for a set similar to a sentence of the new question, and a search result is presented in a manner that the sentences of question, asking back, reply, and answer are associated with the set similar to the sentence of the new question.

Abstract: A message receiving unit receives a message from a user. A message memory stores a plurality of messages each received by the message receiving unit. A set decision unit decides whether the received message is related to at least one message stored in the message memory. A set information memory stores a message set including the received message and the at least one message if the set decision unit decides that the received message is related to the at least one message. A set information edit unit edits a set relation among a plurality of message sets in response to the user's indication. The set information memory stores the set relation edited by the set information edit unit.

Abstract: A learning support system detects an input operation by each user, whenever he operates his terminal apparatus, stores a learning history of each user whenever input operation is detected, learning history including input operation and first time period which is time period from starting time when he starts learning until when input operation is detected, to obtain set of learning histories corresponding to each user and being stored from starting time until when he finishes to learn learning material, retrieves, whenever predetermined time period elapses from starting time corresponding to first user, one learning history, to obtain retrieved learning history whose first time period is equal to second time period from starting time corresponding to first user until when predetermined time period elapses, from sets of learning histories corresponding to second user, and displays retrieved learning history on first user's terminal apparatus.

Abstract: A teaching material memory stores teaching material consisting of multimedia data. A teaching material presentation unit presents the teaching material. An operation unit inputs operation information from a learner for the teaching material presented. A condition information input unit acquires condition information representing the learner's condition. A learning condition decision unit decides a learning condition of the learner based on the condition information, presentation situation of the teaching material, and the operation information. A learning condition memory correspondingly stores the learning condition and the presentation situation of the teaching material as time series information. A presentation method decision unit determines a presentation method of the teaching material and the time series information based on the learning condition. A learning condition presentation unit presents the time series information to the learner based on the presentation method.
