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
