粵文錯別字修正器

呢個係隻粵文錯別字修正器，會自動改正常見嘅粵文錯別字。

本修正器採用嘅正字法見粵文常見錯別字

依賴

Python >= 3.9
PyCantonese

用法

隻修正器可以輸入多個文檔，然後默認輸出到 /output 度。佢默認輸入文件入面每一行都係一句話。運行下面嘅命令就得：

# 可以指定輸出路徑
python3 main.py --inputs input1.txt input2.txt --outdir output
# 亦可以剩係指定輸入，輸出會默認喺 /output
python3 main.py --inputs input.txt

原理

錯別字修正主要分兩種：規則錯別字同上下文錯別字。規則錯別字可以直接通過正則表達式替換嚟解決，例如on9永遠都可以直接替換成戇鳩，無需考慮上下文。上下文錯別字需要睇埋個詞嘅意義同語境先可以判斷得到佢個正字係乜。所有嘅規則錯別字都直接用正則表達式替換嚟修復，規則全部放喺 regular.txt 入面。上下文錯別字嘅修復規則都寫喺 rules.py 入面。每句輸入都會先修復規則錯別字，然後用 PyCantonese 分詞同標詞性，跟住rules.py先會根據每個詞詞性同上下文嚟修正錯別字。
