Title:
Harmful write detection device and detection method on the Internet
Document Type and Number:
Japanese Patent JP6301119
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a detection device and a detection method capable of effectively and efficiently detecting harmful posting on the Internet.SOLUTION: An Internet harmful posting detection device includes: a knowledge base configured by classifying words of harmful expressions as specific words into a plurality of categories in advance; a specific-word acquisition means acquiring specific words in each category while referring to a specific word list of the knowledge base for text posted on a predetermined Internet website; related-expression acquisition means acquiring a related expression including each of the specific words acquired by the specific-word acquisition means; association calculation means calculating an association of the expression acquired by the related-expression acquisition means with each category of the specific word included in the related expression; and determination means defining a maximum value of the association obtained by the association calculation means as a harmful polarity value of the posted text, and determining whether the harmful polarity value is harmful as compared with a preset threshold.
