Now that we have a basic Lexical Analysis and have identified syntax (sentences  and parts of speech), we need to add customer dictionaries for identifying the  tokens that are necessary for identifying customer complaints: Products,  packages, and their attributes.

Preferred practice:  The best resource for finding words and patterns is your  collection data. It is always better to use dictionaries rather than using rules.  Dictionaries are easier to maintain and expand, and also better for  performance.  The source of customer dictionaries is managed by a local database in the ICA  Studio project.
