Abstract
The information processing device generates headings from structured documents. The acquisition means acquires a structured document including headings and texts. The feature word extraction means extracts feature words from subordinate elements of the heading for the headings included in the structured document. The heading generation means generates a new heading corresponding to the subordinate elements based on the extracted feature words.
Claims12
An information processing device comprising:
- a memory storing instructions;
- and
- one or more processors configured to execute the instructions to:
- acquire a structured document including a heading and text;
- generate, for the heading included in the structured document, a matrix of frequency of occurrence of words appearing in documents of subordinate elements of the heading;
- extract, for the heading, feature words by reducing dimensions of the words appearing in the documents using principal component analysis (PCA);
- generate a new heading based on the extracted feature words;
- and
- generate a corrected structured document by replacing the heading with the new heading.
An information processing method performed by a computer and comprising:
- acquiring a structured document including a heading and text;
- generating, for the heading included in the structured document, a matrix of frequency of occurrence of words appearing in documents of subordinate elements of the heading;
- extracting, for the heading, feature words by reducing dimensions of the words appearing in the documents using principal component analysis (PCA);
- generating a new heading based on the extracted feature words;
- and
- generating a corrected document by replacing the heading with the new heading.
A non-transitory computer-readable recording medium storing a program executable by a computer to perform processing comprising:
- acquiring a structured document including a heading and text;
- generating, for the heading included in the structured document, a matrix of frequency of occurrence of words appearing in documents of subordinate elements of the heading;
- extracting, for the heading, feature words by reducing dimensions of the words appearing in the documents using principal component analysis (PCA);
- generating a new heading based on the extracted feature words;
- and
- generating a corrected document by replacing the heading with the new heading.
