Claim:
1. A method for detecting a dangerous expression based on a particular theme, comprising: acquiring, by a first electronic apparatus, from text data for learning, a first subset of the text data associated with the particular theme and with particular time period information; extracting second text data containing negative information, based on an appearance of at least one negative word, from the acquired first subset of the text data; extracting a first at least one word different from the at least one negative word and having a high correlation with the extracted second text data, wherein the first at least one word is determined to have a high correlation with the extracted second text data based on a first product divided by a second product being greater than one, wherein the first product comprises a first number of portions of the text data for learning multiplied by a second number of appearances of the first at least one word in the first subset of the text data for learning, wherein the second product comprises a third number of portions of the first subset of the text data for learning multiplied by a fourth number of appearances of the first at least one word in the text data for learning; determining that the extracted first at least one word different from the at least one negative word is the dangerous expression based on the particular theme and creating a learned learning model associating the dangerous expression to the particular theme; acquiring, by a second electronic apparatus, a second subset of text data associated with the particular theme, wherein the first electronic apparatus is connected to the second electronic apparatus by a network, and wherein the second subset of text data comprises text for posting on a social networking site; detecting that the dangerous expression determined to be the dangerous expression by the learned learning model exists in the second subset of text data acquired by the second electronic apparatus; displaying, on a screen of the second electronic apparatus, an indication that the second subset of text data contains the dangerous expression; and posting, from the second electronic apparatus and to the social networking site, a modified version of the second subset of text data in response to the indication that the second subset of text data contains the dangerous expression, wherein the modified version of the second subset of text data is generated based on user input.
