Play list generation device, audio information provision device, audio information provision system, method, program and recording medium

A play list generation method for generating a play list of a first set of audio information streams in an order to be reproduced by a reproduction device, the play list generation method comprising the steps of:

• receiving a condition of a target to which the first set of audio information streams reproduced by the reproduction device are to be provided;
• acquiring a transfer information stream which represents a transfer of impressions given to the target by reproduction of a second set of audio information streams in a prescribed order based on the condition;
• and
• selecting, from a first plurality of audio information streams stored in a first database, a second plurality of audio information streams which give the target a transfer of impressions proximate to the transfer of impressions represented by the transfer information stream, and generating a play list including the selected second plurality of audio information streams as the first set of audio information streams.

A program for causing a computer to execute generation processing of a play list of a first set of audio information streams in an order to be reproduced by a reproduction device, wherein the generation processing includes the steps of:

• receiving a condition of a target to which the first set of audio information streams reproduced by the reproduction device are to be provided;
• acquiring a transfer information stream which represents a transfer of impressions given to the target by reproduction of a second set of audio information streams in a prescribed order based on the condition;
• and
• selecting, from a first plurality of audio information streams stored in a database, a second plurality of audio information streams which give the target a transfer of impressions proximate to the transfer of impressions represented by the transfer information stream, and generating a play list including the selected second plurality of audio information streams as the first set of audio information streams.

A computer-readable recording medium storing a program for causing a computer to execute generation processing of a play list of a first set of audio information streams in an order to be reproduced by a reproduction device, wherein the generation processing includes the steps of:

• receiving a condition of a target to which the first set of audio information streams reproduced by the reproduction device are to be provided;
• acquiring a transfer information stream which represents a transfer of impressions given to the target by reproduction of a second set of audio information streams in a prescribed order based on the condition;
• and
• selecting, from a first plurality of audio information streams stored in a database, a second plurality of audio information streams which give the target a transfer of impressions proximate to the transfer of impressions represented by the transfer information stream, and generating a play list including the selected second plurality of audio information streams as the first set of audio information streams.

An audio information provision system, comprising:

• a server for generating a play list of a first set of audio information streams in an order to be reproduced by a reproduction device;
• and
• a terminal connected to the server via a network,
• wherein:
• the terminal includes a condition input section for receiving a condition of a target to which the first set of audio information streams reproduced by the reproduction device are to be provided,
• the server includes:
• a database storing a plurality of audio information streams,
• a transfer information stream acquisition section for acquiring a transfer information stream which represents a transfer of impressions given to the target by reproduction of a second set of audio information streams in a prescribed order based on the condition,
• a play list generation section for generating a play list for selecting, from the first plurality of audio information streams stored in the database, a second plurality of audio information streams which give the target a transfer of impressions proximate to the transfer of impressions represented by the transfer information stream, and generating a play list including the selected second plurality of audio information streams as the first set of audio information streams, and
• an output section for outputting the generated play list, and
• the terminal includes:
• a storage section for storing the play list received from the server, and
• the reproduction device for reproducing the first set of audio information streams.
