14. A computer program product for domain specific normalization of a corpus of text, the computer program product comprising: a non-transitory computer readable storage medium comprising a device having computer readable program code embodied therewith, the computer readable program code comprising: computer readable program code for loading a corpus of text in memory of a computer; computer readable program code for determining a domain for the corpus of text by recognizing a presence of words or phrases in the loaded corpus of text that had been previously correlated to the domain; computer readable program code for retrieving a lexicon of replacement words for the determined domain, the lexicon comprising a set of source terms, at least one of the source terms being mapped to one of multiple different replacement terms having a complexity value aligned with an average complexity value for the multiple different replacement terms; and, computer readable program code for text simplifying the corpus of text using the retrieved lexicon by replacing existing words in the corpus of text with the replacement words.
