About the project
Government Service Query Classifier is an automaton-based chatbot built for an Automata Theory assignment. A Deterministic Finite Automaton implemented in pure Python moves through keyword-based state transitions to classify citizen queries into 12 Sri Lankan government services, or reject them. A Flask web interface shows the classification and the state transition, in English, Sinhala and Tamil.
