- A credit card fraud monitoring system. it was developed in part from the application of knowledge discovery in databases (kdd) techniques see also: knowledge discovery in databases. probabilistic context free grammar (pcfg) these are grammars that are developed from large databases of text. the grammars attach probabilities to the various productions in the grammar. if the grammars are developed using supervised learning (i.e., a tagged text corpus), the probabilities can be directly estimated by counting the various productions and perhaps smoothing or otherwise post-processing the results. for an unsupervised corpus, some form of estimation and maximization strategy needs to be employed.
