Shopping Butler

A conversational shopping agent for the TechJam Conversational E-Commerce Search Challenge. Shopping Butler routes each turn onto one of two tracks — a narrow, phrase-locked Buying track once the customer has stated concrete constraints, or a wide, category-driven Browsing track while they haven't — then re-scores the retrieved candidates by verbatim constraint-phrase containment to close in on the customer's hidden target product within 10 turns.

The name reflects what it's built to do: attend closely to what the customer actually says, ask only the follow-up questions that narrow the search, and find the right product in as few turns as possible.
