word2ind

단어를 인코딩 인덱스에 매핑하기

설명

예제

M = word2ind(enc,words)는 인코딩 enc에 있는 words의 인덱스를 반환합니다. 이 함수는 기본적으로 대/소문자를 구분합니다.

예제

M = word2ind(enc,words,'IgnoreCase',true)는 앞의 구문을 사용하여 대/소문자를 무시한 경우의 인덱스를 반환합니다. 인코딩의 여러 단어가 대/소문자만 다른 경우 이 함수는 그 중 하나에 해당하는 인덱스를 반환하며 어떤 특정 인덱스를 반환하지 않습니다.

예제 데이터를 불러옵니다. 파일 sonnetsPreprocessed.txt에는 셰익스피어 소네트의 전처리된 버전이 들어 있습니다. 파일에는 한 줄에 하나씩 소네트가 들어 있으며 단어가 공백으로 구분되어 있습니다. sonnetsPreprocessed.txt에서 텍스트를 추출하고, 추출한 텍스트를 새 줄 문자에서 문서로 분할한 후 그 문서를 토큰화합니다.

단어 인코딩을 만듭니다.

enc = wordEncoding(documents)
enc = 
  wordEncoding with properties:

      NumWords: 3092
    Vocabulary: [1x3092 string]

word2ind 함수를 사용하여 단어 "rose", "love" 및 "beauty"를 인코딩 인덱스에 매핑합니다.

words = ["rose" "love" "beauty"];
idx = word2ind(enc,words)
idx = 1×3

입력 단어 인코딩으로, wordEncoding 객체로 지정됩니다.

입력 단어로, string형 벡터, 문자형 벡터 또는 문자형 벡터로 구성된 셀형 배열로 지정됩니다. words를 문자형 벡터로 지정할 경우 이 함수는 인수를 단일 단어로 처리합니다.

데이터형: string | char | cell
