Abstract

Selected character strings are automatically found by performing an automatic search of a text to find character strings that match any of a list of selected strings. The automatic search includes a series of iterations, each with a starting point in the text. Each iteration determines whether its starting point is followed by a character string that matches any of the list of selected strings and that ends at a probable string ending. Each iteration also finds a starting point for the next iteration that is a probable string beginning. The selected strings can be words and multiple word expressions, in which case probable string endings and beginnings are word boundaries. A finite state lexicon, such as a finite state transducer or a finite state automation, can be used to determine whether character strings match the list of selected strings. A tokenizing automation can be used to find starting points.
