Sentence data analysis information generation device using ontology, sentence data analysis information generation method, and sentence data analysis information generation program

An ontology-based text data analysis information generation method comprising:

• generating dependence relationship tree information that indicates, in a tree structure, a dependence relationship between words in text data to be analyzed;
• extracting a subject, a predicate, and an object from the text data based on the dependence relationship tree information, and generating graph information that indicates, in a graph structure, triple information of ontology that consists of the extracted subject, predicate, and object;
• and
• extracting two suitable components from the text data, acquiring broader concept information that is common between the two components, and adding the acquired broader concept information to the graph information as a parent node that is common between the two components so as to generate text data analysis information.

A non-transitory computer readable medium storing one or more instructions causing a computer to execute:

• generating dependence relationship tree information that indicates, in a tree structure, a dependence relationship between words in text data to be analyzed;
• extracting a subject, a predicate, and an object from the text data based on the dependence relationship tree information, and generating graph information that indicates, in a graph structure, triple information of ontology that consists of the extracted subject, predicate, and object;
• and
• extracting two suitable components from the text data, acquiring broader concept information that is common between the two components, and adding the acquired broader concept information to the graph information as a parent node that is common between the two components so as to generate text data analysis information.
