Duckling is a Clojure library that parses text into structured data:
“the first Tuesday of October” => {:value "2014-10-07T00:00:00.000-07:00"
:grain :day}
You can try it out at https://duckling.wit.ai
See our blog post announcement for more context.
To use Duckling in your project, you just need two functions: load! to load the default configuration, and parse to parse a string.
(ns myproject.core
(:require [duckling.core :as p]))
(p/load!) ;; Load all languages
(p/parse :en$core ;; core configuration for English ; see also :fr$core, :es$core, :zh$core
"wake me up the last Monday of January 2015 at 6am"
[:time]) ;; We are interested in :time expressions only ; see also :duration, :temperature, etc.
;; => [{:label :time
;; :start 15
;; :end 49
;; :value {:type "value", :value "2015-01-26T06:00:00.000-02:00", :grain :hour}
;; :body "last Monday of January 2015 at 6am"}]See the documentation for more information.
