This paper is devoted to the study of textual inference, the presenta-tion of different applications of the Recognition of Textual Inference (RTE) and the main levels of textual inferences. We show the stages of development of the challenge Pascale RTE, which is implemented to assess the advances of re-search groups in this field, and we conclude with the presentation of some in-ference methods used by research groups evaluated in the challenge Pascal RTE.
