morpheme-match

morpheme-match provide match function that match token with sentence.

形態素解析したトークンを元に、文章にマッチするトークンが含まれているかをチェックするライブラリ。

Install

Install with npm:

Usage

createTokenMatcher(expectedTokens): function

createTokenMatcher() return function(token): { match: boolean, tokens?: Array, skipped? Array }.

We want to check "名詞かもしれない" contain "かも" token. Write following:

See example code with azu.github.io/morpheme-match/#名詞(かも)しれない.

import {createTokenMatcher} from "morpheme-match";
const matchToken = createTokenMatcher([
    {
        "surface_form": "かも",
        "pos": "助詞",
        "pos_detail_1": "副助詞",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "*",
        "conjugated_form": "*",
        "basic_form": "かも",
        "reading": "カモ",
        "pronunciation": "カモ"
    }
]);
const tokens = [
    {
        "surface_form": "名詞",
        "pos": "名詞",
        "pos_detail_1": "一般",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "*",
        "conjugated_form": "*",
        "basic_form": "名詞",
        "reading": "メイシ",
        "pronunciation": "メイシ"
    },
    // Hit!
    {
        "surface_form": "かも",
        "pos": "助詞",
        "pos_detail_1": "副助詞",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "*",
        "conjugated_form": "*",
        "basic_form": "かも",
        "reading": "カモ",
        "pronunciation": "カモ"
    },
    {
        "surface_form": "しれ",
        "pos": "動詞",
        "pos_detail_1": "自立",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "一段",
        "conjugated_form": "未然形",
        "basic_form": "しれる",
        "reading": "シレ",
        "pronunciation": "シレ"
    },
    {
        "surface_form": "ない",
        "pos": "助動詞",
        "pos_detail_1": "*",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "特殊・ナイ",
        "conjugated_form": "基本形",
        "basic_form": "ない",
        "reading": "ナイ",
        "pronunciation": "ナイ"
    }
];
const result = tokens.some(token => {
    const {match} = matchToken(token);
    return match;
});
console.log(result);// true

If want to get matched token, write following:

let resultTokens = [];
const result = tokens.some(token => {
    const {match, tokens, skipped} = matchToken(token);
    resultTokens = tokens;
    return match;
});
console.log(resultTokens);
/*
[ { surface_form: 'かも',
    pos: '助詞',
    pos_detail_1: '副助詞',
    pos_detail_2: '*',
    pos_detail_3: '*',
    conjugated_type: '*',
    conjugated_form: '*',
    basic_form: 'かも',
    reading: 'カモ',
    pronunciation: 'カモ' } ]
*/

Tips

morpheme-matchは_から始まるキーを無視するため、メタ情報は_で書き込む事ができます。

const matchToken = createTokenMatcher([
    {
        "surface_form": "かも",
        "pos": "助詞",
        "pos_detail_1": "副助詞",
        "pos_detail_2": "*",
        "pos_detail_3": "*",
        "conjugated_type": "*",
        "conjugated_form": "*",
        "basic_form": "かも",
        "reading": "カモ",
        "pronunciation": "カモ",
        "_cature": "$1"
    }
]);

キー_skippableがtrueの場合はマッチしない場合は無視されます。

const matchToken = createTokenMatcher([
    {
        "surface_form": "かも",
    },
    {
        "surface_form": "、",
        "_skippable": true,
    },
    {
        "surface_form": "しれ",
    },
]);
