Abstract:
The present disclosure discloses an artificial intelligence based method and apparatus for segmenting a sentence. A specific embodiment of the method includes: lexing a to-be-segmented original sentence to obtain a set of words in the original sentence; performing sentence segmentation steps on a to-be-segmented sentence having an initial value being the original sentence; using the sub-sentence fragment not belonging to the set of words as the to-be-segmented sentence and continuing to perform the sentence segmentation steps, if the sub-sentence fragment not belonging to the set of words exists; and storing the original sentence in association with the plurality of sub-sentence fragments each time obtained by performing the sentence segmentation steps. The embodiment generates a segmentation result obtained by performing a multi-layered segmentation to the original sentence.

Claim (Index 2):
The method according to  claim 1 , wherein the segmenting the to-be-segmented sentence into a plurality of sub-sentence fragments according to a record of being searched in a search engine for a word combination composed of a single word or different words in the to-be-segmented sentence comprises:\n extracting at least one type of feature vector according to the record of being searched in the search engine for the word combination composed of the single word or the different words in the to-be-segmented sentence; inputting the at least one type of feature vector into a recurrent neural network model to determine a segmentation point for segmenting the to-be-segmented sentence based on a sequence output by the recurrent neural network model, wherein the recurrent neural network model is used to characterize a correspondence between the at least one type of feature vector extracted according to the record of being searched in the search engine for the word combination composed of the single word or the different words in the to-be-segmented sentence and a description for whether words in the to-be-segmented sentence are in a sequence at the segmenting; and segmenting the to-be-segmented sentence into the plurality of sub-sentence fragments according to the determined segmentation point.
