Abstract

An information processing apparatus includes a display, an input unit, and a controller. The input unit is configured to receive an input of a first keyword from a user. The controller is configured to retrieve first character information including the input first keyword from a database configured to store a plurality of character information items converted from a plurality of voice information items by voice recognition processing, extract a second keyword that is included in the first character information acquired by the retrieval and is different from the first keyword, and control the display to display a list of items including first identification information with which the acquired first character information is identified and the second keyword included in the first character information.

Claims

1. An information processing apparatus, comprising:

a display;

an input unit configured to receive an input of a first keyword from a user; and

a controller configured to

retrieve first character information including the input first keyword from a database configured to store a plurality of character information items converted from a plurality of voice information items by voice recognition processing,

extract a second keyword that is included in the first character information acquired by the retrieval and is different from the first keyword, and

control the display to display a list of items including first identification information with which the acquired first character information is identified and the second keyword included in the first character information.

2. The information processing apparatus according to claim 1, wherein

the controller

retrieves, when an operation of the user to select the second keyword included in the displayed items is received, second character information including the second keyword from the database,

extracts a third keyword that is included in the second character information acquired by the retrieval and is different from the second keyword, and

controls the display to display a list of items including second identification information with which the acquired second character information is identified and the third keyword included in the second character information.

3. The information processing apparatus according to claim 1, wherein

the database stores a plurality of summary information items obtained by summarizing the plurality of character information items, and

the controller

acquires, when an operation of the user to select one of the displayed items is received, a summary information item corresponding to the selected item from the database, and

controls the display to display the acquired summary information item.

4. The information processing apparatus according to claim 3, wherein

the controller

controls the display to display the summary information item in a state where a third keyword included in the summary information item is selectable,

retrieves, when an operation of the user to select the displayed third keyword is received, third character information including the third keyword from the database,

extracts a fourth keyword that is included in the third character information acquired by the retrieval and is different from the third keyword, and

controls the display to display a list of items including third identification information with which the acquired third character information is identified and the fourth keyword included in the third character information.

5. The information processing apparatus according to claim 3, wherein

the controller replays, when an operation of the user to designate an arbitrary position of the displayed summary information item is received, one of the plurality of voice information items that corresponds to a character information item as a summary source of the summary information item, from a replay position corresponding to a character string displayed at the designated position.

6. An information processing method, comprising:

receiving an input of a first keyword from a user;

retrieving first character information including the input first keyword from a database configured to store a plurality of character information items converted from a plurality of voice information items by voice recognition processing;

extracting a second keyword that is included in the first character information acquired by the retrieval and is different from the first keyword; and

displaying a list of items including first identification information with which the acquired first character information is identified and the second keyword included in the first character information.

7. A program causing an information processing apparatus to execute the steps of:

receiving an input of a first keyword from a user;

retrieving first character information including the input first keyword from a database configured to store a plurality of character information items converted from a plurality of voice information items by voice recognition processing;

extracting a second keyword that is included in the first character information acquired by the retrieval and is different from the first keyword; and

displaying a list of items including first identification information with which the acquired first character information is identified and the second keyword included in the first character information.
