Duckling (old) is a Clojure library that parses natural language text into structured data, such as extracting dates, times, and durations from phrases. It is deprecated since May 2017 in favor of the rewritten Haskell version at facebook/duckling.
Use cases
- parse dates and times from natural language text
- extract durations and temperatures from user input
- turn phrases like 'the first Tuesday of October' into structured data
- build an NLU layer for a chatbot
- parse multilingual text into entities
When to choose
- you are already maintaining a legacy Clojure/JVM project that uses the original Duckling
- you need the original Clojure implementation for compatibility reasons
When to avoid
- starting a new project - use facebook/duckling (Haskell) instead
- you need actively maintained code or recent fixes
- you need a non-JVM runtime
