LOGIFOLG is a system and method for finding implicit information that is not explicitly mentioned in the sentence, not contained in the synonyms of the particular word, not present in the concept the word belongs to, not found with statistical or concordance based analysis. Nevertheless, this implicit information is present and understood, implicitly, consciously or unconsciously, by everybody who reads the text. LOGIFOLG uses a computer software process, such as computer-executable program code, to discover this implicit information. The steps in this process are: analyzing user's written input, up to five successive and non-successive words in a sequence, understanding the meaning of the written input, finding implicit information in the written input and finally, displaying the implicit information as a variant of the original sentence. The subject matter of the invention deals with Artificial Reasoning, namely inductive and deductive reasoning, based on Natural Language written sentences. The medium is non-transitory.
