1. StockBroker (An NLP Dialog Manager) Client Dr. Wang, Researcher, Speech Recognition, IBN, Yorktown Heights, NY Developed by Arati Avhad Larry Lefever

2. Introduction The application is essentially a “dialog manager” that supports natural language commands for buying and selling stock in corporations. Two servers are used, a "Classer" and a "Parser". These servers provide the Natural Language Processing functionality.

3. Use Cases Currently, only two "use-cases" are supported: Buy shares of a stock Sell shares of a stock - The user enters a natural-language request to buy/sell stock. Expected format (some variations allowed): “... {action}... {integer}... {shares | dollars | percentage}... {stock-symbol} - The application responds with confirmation of the requested action - The application displays the ready-message
