Sentence boundary disambiguation (SBD), also known as sentence breaking, sentence boundary detection, and sentence segmentation, is the problem in natural language processing of deciding where sentences begin and end.
Word segmentation is the problem of dividing a string of written language into its component words. In English and many other languages using some form of the Latin alphabet, the space is a good approximation of a word divider (word delimiter), although this concept has limits because of the variability with which languages emically regard collocations and compounds.
For most spoken languages, the boundaries between lexical units are difficult to identify; phonotactics are one answer to this issue. One might expect that the inter-word spaces used by many written languages like English or Spanish would correspond to pauses in their spoken version, but that is true only in very slow speech, when the speaker deliberately inserts those pauses.
Sentence breaking (also known as sentence boundary disambiguation and sentence detection) – given a chunk of text, finds the sentence boundaries. Sentence boundaries are often marked by periods or other punctuation marks, but these same characters can serve other purposes (e.g. marking abbreviations).
The development of connectionist models that when implemented are able to successfully learn words and syntactical conventions [43] supports the predictions of statistical learning theories of language acquisition, as do empirical studies of children's detection of word boundaries. [44]
Word boundary detection In the known spoken language, there are no gaps between words; where to situate the word boundary many times depends on what choice makes the most sense grammatically and given the context.

For example, Millotte et al. (2010) tested 16-month olds, observing how children use phonological phrase boundaries to constrain lexical access. When infants heard a prosodic boundary, they were able to detect the existence of a word boundary.
