Abstract
Provided are systems, methods, and devices for providing word replaceability information through word vectors. Within a database system, a text document is received, then processed into a number of sub-sentences or sub-segments. The processing involved delimiting one or more sentences within the text document by one or more punctuation marks. Next, a number of n-gram combinations are generated according to co-appearances of n-grams within the sub-sentences. Distance metrics are determined between the n-gram co-appearances for each n-gram combination. Finally, word replaceability information is provided for one or more words or n-grams within the text document, based on the distance metric.
