Mystem

The Elixir wrapper of the Yandex Mystem 3 morphological analyzer

A Quick Example

Lemmatization

iex(1)> text = "Красивая мама красиво мыла раму"
"Красивая мама красиво мыла раму"
iex(2)> {:ok, lemmas} = Mystem.lemmatize(text)
{:ok,
["красивый", "мама", "красиво", "мыть", "рама"]}
iex(3)> lemmas |> Enum.join(" ")
"красивый мама красиво мыть рама"

Getting grammatical information and lemmas.

iex(4)> {:ok, analyze} = Mystem.analyze(text)
{:ok,
  [
    %{
      "analysis" => [
        %{
          "gr" => "A=им,ед,полн,жен",
          "lex" => "красивый",
          "wt" => 1
        }
      ],
      "text" => "Красивая"
    },
    %{
      "analysis" => [
        %{"gr" => "S,жен,од=им,ед", "lex" => "мама", "wt" => 1}
      ],
      "text" => "мама"
    },
    %{
      "analysis" => [
        %{"gr" => "ADV=", "lex" => "красиво", "wt" => 0.8149252476}
      ],
      "text" => "красиво"
    },
