In the method, a text part defined by a user using a 1st language L1 is extracted (a), a token-like text part is generated by expressing the text part by tokens (b), parts of speech in the token-like text part are defined and a defined text part in which at least one speech part indicator is added to a word is generated (c), the defined text part is lemmatized, and when a word or a lemma is obtained in each word of the defined text part, the word or the lemma is generated (d), the text part determining a lemma in each word is translated and at least one equivalent word (each equivalent word of each word can be translated to a 2nd langage L2) is generated in each word (e), and the equivalent word is formated in order to define an inquiry sutable for retrieving the information of the 2nd language L2 (f).</p> |
