ChatterBot

A Python-based conversational engine that uses machine learning to generate automated responses from collections of real-world dialogue.

ChatterBot utilizes a language-independent design to train bots in any tongue (English, Spanish, and German included) by processing data sets into a logic-based search graph. The library employs a series of Adapter classes (Storage, Logic, and Preprocessors) to handle everything from SQL database management to Levenshtein distance calculations for statement matching. It is built for developers who need a self-contained, trainable NLP solution without relying on external cloud APIs.
