A system for visually representing user behavior within an interactive voice response (IVR) system of a call processing center generates a complete sequence of events within the IVR system for plural calls to the call processing center, the plurality of calls being recorded from end to end. A call flow of the IVR system is modeled as a non-deterministic finite-state machine, such that a start state of the finite-state machine represents a first prompt of the IVR system, other states of the finite-state machine represent subsequent prompts at which a branching occurs in the call flow of the IVR system, exit conditions are represented as end states, and transitions of the finite-state machine represent transitions between call flow states triggered by data inputted by a user or by internal processing of the IVR system. The complete sequences of events for the plural calls are provided to the finite-state machine to produce a two-way matrix of several counters. The data from the two-way matrix is represented as a state-transition diagram.

An XML parsing system includes a pattern-matching system 1 that receives an input stream 2 of characters corresponding to the XML document to be parsed, and provides an output 3 for subsequent processing in software by a processor 4. The pattern matching system 1 includes two main components, a controller in the form of a programmable state machine 5, which is programmed with an appropriate state transition diagram 6, and a character processing unit 7 in the form of a token and character handler. The programmable state machine 5 controls the character processing unit 7 to, e.g., compare characters in the input character stream 2 with other received or stored characters. The character processing unit 7 then provides feedback to the programmable state machine controller 5, e.g., as to whether the compared characters match, so that the programmable state machine controller 5 can then parse the received document accordingly.

State-transition-diagram information storing means stores information concerning a state transition diagram where source nodes of a source structured document transit in order of occurrence from the head thereof. Extracting means extracting, a pair consisting of a new node and a corresponding source node in accordance with order of occurrence. Matching means determining whether the source and new nodes in the selection pair have matchingness, on the basis of their descriptions. Node qualifying means qualifying the source node as a node to be used for the new node. Transition-history information generating means generates, as transition-history information, information concerning a transition history regarding the node to be used. Degree-of-approximateness detecting means detects a degree of approximateness between the source structured document and the new structured document on the basis of the transition-history information.

Data life cycle policies are developed by classifying data into data classes based upon predetermined data attributes. States are then specified in which the data classes may reside. Components are defined that support one or more of the states. Transfer agents support transferring data from one component to another component. A state transition diagram is prepared for each data class, including one or more conditions that are necessary for each transition between states. An algorithm is applied to the state transition diagram which generates policies that generate life cycle actions if the data or file belongs to the class, the present state of the data or file, and if the conditions for the transitions between the states for each data class have been met. The algorithm provides a method and system for developing data life cycle policies.
