CH2 三個重要方法

corpus 的定義

the notion of “corpus” refers to a machine-readable collection of (spoken or written) texts that were produced in a natural communicative setting, and the collection of texts is compiled with the intention (I) to be representative and balanced with respe<:t to a particular linguistic variety or register or genre and (2) to be analyzed linguistically.

各種 corpora

general vs. specific

raw vs. annotated

幾種annoation:

  • lemmatized
  • POS tag
  • morphological
  • phonological
  • syntactically parsed
  • etc.

    歷時 vs. 共時

    靜態 vs. 動態

corpora能提供什麼資訊

簡單來說就是頻率：

  • 各種pattern的出現頻率
  • pattern之間的共同出現頻率

Frequency

詞的頻率。

但什麼是詞？不同語言中的詞。

type vs. token

從頻率能看出些什麼 (p. 14)

Collocation

Lexical Co-occurence

三種co-occurence

  • collocation (本篇重點)
  • colligation
  • collostruction

應用

  • 語言教學
  • 語義學

Concordance

(Lexico-)Grammatical Co-occurence

相較於collocation，concordance關注的是一個詞所處於的更大的脈絡。
