Abstract

A summary generating device includes a featural script extracting unit, a segment candidate generating unit, and a structuring estimating unit. The featural script extracting unit extracts featural script information of the words included in text information. Based on the extracted feature script information, the segment candidate generating unit generates candidates of segments that represent the constitutional units for the display purpose. Based on the generated candidates of segments and based on an estimation model for structuring, the structuring estimating unit estimates structure information containing information ranging from information of a comprehensive structure level to information of a local structure level.

Claims

1. A summary generating device comprising:

a featural script extracting unit that extracts featural script information from text information;

a segment candidate generating unit implemented in computer hardware comprising one or more hardware processors that, based at least in part on the extracted feature script information, generates candidates of segments representing constitutional units for display; and

a structuring estimating unit implemented in computer hardware comprising one or more hardware processors that estimates structure information based at least in part on the generated candidates of segments and an estimation model for structuring, the structure information comprising information organized from a comprehensive structure level to a local structure level.

2. The summary generating device according to claim 1, further comprising a voice recognizing unit that performs voice recognition with respect to voice data and generates the text information based on the voice recognition of the voice data, wherein

the featural script extracting unit extracts featural script of words included in the generated text information.

3. The summary generating device according to claim 2, wherein

the voice recognizing unit generates the text information to include character information of utterances and timings of the utterances, and extracts audio features of the voice data, and

the featural script extracting unit extracts timings corresponding to the character information and extracts the audio features as surrounding information with respect to the words.

4. The summary generating device according to claim 1, further comprising a display format converting unit that converts the estimated structure information into a display format for viewing.

5. The summary generating device according to claim 1, wherein, the structuring estimating unit presents the structure information with a priority determined based at least in part according to similarities between the structure information and the estimation model, the estimation model comprising learning data obtained from one or more prior processing results.

6. The summary generating device according to claim 4, wherein the display format converting unit changes the display format according to a user instruction.

7. A summary generating method implemented by a summary generating device, the summary generating method comprising:

extracting featural script information of words from text information;

generating, based at least in part on the extracted feature script information, candidates of segments representing constitutional units for display; and

estimating, based at least in part on the generated candidates of segments and an estimation model for structuring, structure information comprising information organized from a comprehensive structure level to a local structure level.

8. A computer program product comprising a non-transitory computer readable medium that comprises a summary generating program, wherein the summary generating program, when executed by a computer, causes the computer to perform:

extracting featural script information of words from text information;

generating, based at least in part on the extracted feature script information, candidates of segments representing constitutional units for display; and

estimating, based at least in part on the generated candidates of segments and an estimation model for structuring, structure information comprising information organized from a comprehensive structure level to of a local structure level.
