[Python] csvの前処理

《 前処理の目的と内容 》

csvダウンロードした特許情報ファイルを編集して、分析に便利な情報を追加する前処理

  1. 〈出願件数〉
    「出願件数」の列(column)を作って、出願件数として全ての行(row)に「1」を入力

  2. 〈筆頭出願人(出願人分析用)〉
    「出願人」欄から、筆頭出願人を抽出。国籍(アルファベット2文字の国コード)が括弧書きされているとき、「出願人の国籍」の列(column)に出力。さらに抽出した「筆頭出願人」と同じデータを「筆頭出願人(名寄せ)」にコピー。「筆頭出願人(名寄せ)」は将来の名寄せ用の元データ。

  3. 〈最先の優先日(年次推移分析用)〉
    「最先優先日」と「最先優先年」の列(column)を追加。「出願日」と「優先日」の欄から最先の日を抽出して「最先優先日」として出力。さらに、抽出した「最先優先日」からその年を抜き出して「最先優先年」として出力。

  4. 〈筆頭IPC(技術分野分析用)〉
    「筆頭IPC(sub-class)」と「筆頭IPC(main-group)」の列(column)を追加。「IPC」の欄から、筆頭IPCを抽出して、サブクラス(先頭の4文字,”H01L”など)を「筆頭IPC(sub-class)」に、メイングループ(先頭の4文字,”H01L”などに続く「数字/数字」の前半部分)を「筆頭IPC(main-group)」に出力。

  5. 〈出願国(出願国分析用)〉
    「JP」「WO」「US」「EP」「CN」「KR」の列(column)を追加。「ファミリー公報」の欄から、作成した列(column)に相当する国・地域への出願があれば「1」なければ「0」を出力。その国・地域への出願の有無を表すフラグ。同じ国・地域内でのファミリー展開に応じた件数は無視して、単に有無のみを判定。

《 プログラムの構成 》

<入力>
csvダウンロードしたデータから構成したEXCELファイル
複数シートを想定して、シート名を指定して処理
<出力>
指定したシート内への列(column)の追加
<プログラム>
上記1~5は関数として定義。処理対象のWokkBook名(EXCELファイル名)とシート名を指定して必要な前処理を実行する関数を呼び出す。
