docke起動(ファイル共有）macOSでpdfファイルのあるフォルダを共有して起動。

macOS

$ docker run -v /tmp/sae:/tmp/sae -it ubuntu /bin/bash

dockerでPDFの道具導入。poppler-utils にpdftotextが入っているらしい。
編集するかもしれないのでvimを入れる。

ubuntu

# apt update; apt -y upgrade
# apt install -y poppler-utils vim

awkのプログラムは

wc.awk

# Print list of word frequencies
# https://researchmap.jp/jomd7nobo-45644/

{
    $0 = tolower($0)    # 
    gsub(/[^a-z_ \t]/, " ", $0)  #
    for (i = 1; i <= NF; i++)
        freq[$i]++
}

END {
    for (word in freq)
        printf "%s\t%d\n", word, freq[word]
}

awk実行

ubuntu

# awk -f wc.awk j1979-da.txt > wc.txt

しまった。どうも表の中の単語を抽出してないっぽい。
いつもは日本語訳をつけるが、今回は見送り。

と思ってvimで開くと、最初の表は単語を抽出している。

検討は明日にしよう。

20211112 2320追記

明日にしようと思ったが、数字も入れて単語帳にしてみて確かめた。

    gsub(/[^a-z_ \t]/, " ", $0)  
を
    gsub(/[^0-9a-z_ \t]/, " ", $0)

にした。

Qiitaで逆リンクを表示しなくなったような気がする。時々、スマフォで表示するとあらわっることがあり、完全に削除したのではなさそう。

４月以降、せっせとリンクリストを作り、統計を取って確率を説明しようとしている。
2025年２月末を目標にしている。
