document: On business activity modeling using grammars Web based applications offer a mainstream channel for businesses to manage their activities . We model such business activity in a grammar-based framework . The Backus Naur form notation is used to represent the syntax of a regular grammar corresponding to Web log patterns of interest . Then , a deterministic finite state machine is used to parse Web logs against the grammar . Detected tasks are associated with metadata such as time taken to perform the activity , and aggregated along relevant corporate dimensions .
