Summary generating device, summary generating method, and computer program product
First Claim
1. A summary generating device comprising:
- a memory; and
one or more processors configured to function as a featural script extracting unit, a segment candidate generating unit and a structuring estimating unit, whereinthe featural script extracting unit extracts featural script information from text information, the featural script information including at least one of a part-of-speech and metadata of a logical element included in the text information, property information of the part-of-speech, and system information related to the summary generating system;
the segment candidate generating unit generates, based at least in part on the extracted featural script information, candidates of segments representing constitutional units for display, and performs ordering of sets of the featural script information; and
a structuring estimating unit estimates structure information comprising structural elements based at least in part on the generated candidates of segments and a structure estimation model, the structural elements comprising a comprehensive structural element that has a comprehensive structure level and a local structural element that has a local structure level, the comprehensive structure level representing a broadest structural element within a hierarchy of the structural elements and the local level representing a narrowest structural element within the hierarchy of the structural elements, the structure estimation model including learning data obtained by learning display formats suitable for displaying and summary results edited or decided prior to the estimation,wherein, the structuring estimating unit presents a structural element of the structural elements having a likelihood that is higher than another structure element of the structural elements, the likelihood being the likelihood with respect to the estimation model.

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.
