This question's explanation and your answers so far.
次の事例のうち，AIを導入することによって業務の作業効率が向上したものだけを全て挙げたものはどれか。 a 食品専門商社のA社が，取引先ごとに様式が異なる手書きの請求書に記載された文字を自動で読み取ってデータ化することによって，事務作業時間を削減した。 b 繊維製造会社のB社が，原材料を取引先に発注する定型的なPCの操作を自動化するツールを導入し，事務部門の人員を削減した。 c 損害保険会社のC社が，自社のコールセンターへの問合せに対して，オペレーターにつなげる前に音声チャットボットでヒアリングを行うことによって，オペレーターの対応時間を短縮した。 d 物流会社のD社が，配送荷物に電子タグを装着して出荷時に配送先を電子タグに書き込み，配送時にそれを確認することによって，誤配送を削減した。
正解 The correct answer is “ア (a, c)”. The only cases that can be said to have introduced AI are those that improved operational efficiency by using intelligent processing such as recognition and judgment by AI. In a, the highly variable characters on handwritten invoices, whose formats differ for each client, are automatically recognized by AI and turned into data, reducing clerical work time through AI character recognition (AI-OCR). In c, before connecting a caller to an operator, a voice chatbot conducts the interview, shortening handling time with AI technologies such as speech recognition and natural language processing. Therefore the two cases made more efficient by AI are a and c, and “ア”, which lists exactly these two with nothing missing or extra, is correct.
“b, c”. c is AI, but b is RPA (Robotic Process Automation) that automates the routine PC operation of ordering raw materials; it is automation that mechanically repeats fixed steps and does not use recognition or judgment by AI. Because it includes b, which is not an AI case, it is wrong.
“b, d”. b is, as stated above, RPA and not AI. d is a mechanism that writes the delivery destination to an electronic tag (RFID) and reads and verifies it during delivery; this too is not AI but RFID, a wireless identification technology. Neither is an AI case, so it is wrong.
“c, d”. c is AI, but d is the writing and verification of the delivery destination via an electronic tag (RFID), and does not use recognition or judgment by AI. Because it includes d, which is not AI, it does not amount to listing only AI cases, so it is wrong.
