Title:
COMPUTER PROGRAM, METHOD AND DEVICE FOR LEARNING HORN CLAUSE COMPOSED OF LITERAL OBTAINED BY EMBEDDING VARIABLE INTO NATURAL LANGUAGE
Document Type and Number:
Japanese Patent JP2020047030
Kind Code:
A
Abstract:
To mechanically learn and deduce a horn clause having a form which is close to a natural language.SOLUTION: A common partial character string in a single text being a learning source is replaced by using a variable which should be constrained by the same value. A horn clause and a co-occurrence tree using a literal which is obtained by embedding the variable into a natural language are obtained. A possibility of a notation fluctuation such as a variable name is automatically dissolved from an integrated view point of the variable name which is replaced from the same term, a character of a substituted value, and a positional relationship of the same name variable between a plurality of the single texts. The adoption/non-adoption and the reliability of the horn clause or the like are calculated by using an adaptable text number, and the adoption/non-adoption, the reliability and the necessity of the horn clause are decided depending on a degree at which the horn clause can derive a character string which does not exist in the text, or a degree allowing the derivation of an existing character string. A user is made to possess a sense by outputting the mechanically-learnt regularity from a text aggregation which is aggregated by being selected by the user. A single replacement prohibition character string which should not be replaced singly is used, and the user learns the horn clause by adding the texts which are conditionally merged to each other to the horn clause.SELECTED DRAWING: None
