    Abstract: This invention provides methods and apparatuses for segmenting text. A method for segmenting a text including a plurality of sentences comprises: extracting a plurality of evidences and a plurality of inferences from the text; for each of said inferences, determining a preferred position for each of said evidences based on the text and/or segmentation histories, wherein the preferred position represents the position that the evidence is the most likely to take in a sequence of evidences which are used to make the inference; and segmenting the text into a plurality of sections by determining one or more of boundaries between every two consecutive sentences in the text as section boundaries based on the preferred positions for the evidences. By virtue of the present invention, the segmentation will be more accurate.
