Description

  The present invention relates to a content presentation device and a content presentation program, and more particularly to a content presentation device and a content presentation program for presenting more appropriate recommended content to a viewer.

  Conventionally, a technique for generating a viewer's preference profile based on a viewing history has been disclosed. They usually generate preference profiles that use program information (summary sentences, genres, performers, etc.) and user (viewer) operation histories in order to estimate individual preferences (for example, patent literature). 1 and 2, see Non-Patent Document 1).

  According to the technique disclosed in Patent Document 1, in order to recommend an appropriate program at the timing requested by the viewer in response to the viewer's program preference, the history information is stored when the recommended button on the remote control is operated. Based on the past channel history information stored in the means, a program similar to a program that can be provided at the current time and often viewed during this time period is selected, and the channel is switched as a recommended program to reproduce the broadcast. If the viewer operates the recommended button on the remote control again within a certain period of time, the next recommended program is selected, the channel is switched and output to the broadcast playback means, and the recommended program is selected. The weight of the presentation pattern is changed.

  Further, in the technique disclosed in Patent Document 2, program information storage means for storing program information, program switching monitoring means for monitoring user operations performed at the time of program selection, program switching monitoring means, and program information A favorite program storage means for obtaining a user's favorite program based on the program priority calculation using the program information storage means and the favorite program storage means, and calculating the calculated program priority. It is used to inform users of recommended programs.

  In the technique disclosed in Non-Patent Document 1, a preference model, which is one of individual sensitivity models, is constructed from product preference information using a CAM (Category-guided Adaptive Modeling) method, and the product is obtained by text mining. Product recommendation suitable for the user's preference is performed based on the assigned sensitivity word and the obtained model.

  Furthermore, there is an information processing apparatus that collects a user's viewing history, determines a viewing schedule in each time frame based on the collected viewing history, and proposes to the user (see, for example, Patent Document 3).

  In the technique disclosed in Patent Literature 3, a preference value indicating a user's viewing trend in each time frame is calculated from the collected user's viewing history, and further, evaluation indicating characteristics of broadcast content, recorded content, and on-demand content. By calculating the value, broadcast content, recorded content, and on-demand content are mixedly arranged in the time frame on the same time axis according to the degree of similarity between the preference value and evaluation value for each time frame, and viewed A schedule is being generated.

  By the way, for example, when a broadcast station provides content such as a program using a VOD (Video On Demand) service or the like, there are many long-time programs whose program length is 30 minutes or 60 minutes or more. Therefore, the viewer preliminarily adjusts the program scale and the schedule that can be viewed by the viewer, and further selects the program to be viewed according to the purchase price and preference.

  For example, general office workers, OLs, students, and the like tend to watch long-length programs slowly on weekday nights and from midday to night on holidays according to their schedules. In many cases, in the morning, users listen to only interesting stories while listening to the program. Furthermore, the viewer views the program while confirming whether or not new costs are incurred by viewing the program.

  However, in the above-described prior art, since the program is selected based on the preference information regardless of the program scale, for example, the selection of the program according to the tendency of the viewer over a certain period such as one week or one month, etc. Is not done. In other words, if a program reflecting a habit that the viewer does not notice is provided, it will be comfortable for the viewer, but there has been no specific method for that purpose.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a content presentation apparatus and a content presentation program for presenting more appropriate recommended content to a viewer.
