Summary generating device, summary generating method, and computer program product

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

• extracting, by the featural script extracting unit, featural script information of words 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;
• generating, by the segment candidate generating unit, based at least in part on the extracted featural script information;
• estimating, by the structuring estimating unit, based at least in part on the generated candidates of segments and a structure estimation model, structure information comprising 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 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;
• and
• performing ordering of sets of the featural script information,
• 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.

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, 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;
• generating, based at least in part on the extracted featural script information, candidates of segments representing constitutional units for display;
• estimating, based at least in part on the generated candidates of segments and a structure estimation model, structure information comprising structure 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;
• and
• performing ordering of sets of the featural script information,
• 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.
