## What it is
AnyQ is Baidu's open-source FAQ-based question answering framework with a configurable, plugin-based architecture covering question analysis, retrieval, matching, and re-ranking. It includes SimNet, a semantic text matching framework with models like BOW, CNN, RNN, MM-DNN, MatchPyramid, MV-LSTM, and K-NRM implemented in PaddlePaddle and TensorFlow.

## Use cases
- build a faq chatbot for customer support
- match user questions to predefined answers semantically
- serve question answering over an http api
- train semantic matching models for chinese text
- customize retrieval and ranking plugins for a qa system

## When to choose
- you need a self-hosted FAQ question answering system with Chinese language support
- you want a plugin-based QA pipeline you can customize with custom retrieval or matching logic
- you need semantic matching models integrated into a retrieval system

## When to avoid
- you need a modern, actively maintained project with recent updates
- you want a managed cloud QA service rather than self-hosted C++ deployment
- your use case is English-only open-domain question answering
