Streamlit + CLI visa chatbot; JSON-powered, swap for any country (demo: Nigeria). # **Visa InfoBot** Visa InfoBot is a portable visa-information chatbot. It separates the conversation logic from the data, so you can reuse the same app with any country’s rules by swapping a single JSON file. This demo uses Nigeria as the example dataset: type a country (e.g., “Bolivia” or “How about Iran?”) and the bot tells you whether a visa is required to enter Nigeria. If a visa is needed, it guides you through visa types and shows the relevant requirements. --- ## Features - Friendly onboarding (“Which country are you from?”) - Country detection in free text (e.g., “How about Iran?”) - Instant visa decision (visa-free vs visa-required) - If visa-required → quick-reply chips for visa types - **General + specific** requirements in one answer - Mid-flow country switch + “same-country” nudge - Admin sidebar: visa-free/required lists & simple analytics - Two interfaces: **HTML web demo** and **CLI (Command-line Interface)** Note: HTML web demo is accessible at: Click here to try the demo --- ## Project Structure ``` Visa-InfoBot/ ├─ visa_demo.html # HTML web interface (primary demo) ├─ interface.py # CLI chat (optional) ├─ Conversation # JSON config (prompts, countries, visa text) ← required ├─ data_loader.py # Helpers for classic intent model ├─ rule_based.py # Greetings/farewell & small rules ├─ model_intent.py # Tfidf + Naive Bayes (fallback intent model) ├─ visa_intent_model.pkl # (optional) saved model └─ README.md ``` --- **Troubleshooting** - **File not found:** Conversation The app can’t see its config file. Make sure a file named Conversation (capital C, no extension) is in the same folder as streamlit_app.py. If you renamed it, update CONFIG_PATH in streamlit_app.py. - **New chat doesn’t clear** Streamlit keeps session state between reruns. Use Sidebar → Admin → New chat to reset. The app also auto-resets when the Conversation file changes (modified time/size). - **Enter doesn’t send (requires two presses)** First, enter didn’t send? Just type …
