Zusammenfassung:To provide a device capable of easily learning an operating state that damages a work machine.SOLUTION: An operating state calculation device for a work machine includes a processor and an output device. The processor calculates a feature vector with operation information as a feature amount in each time, and assigns a classification ID to the feature vector on the basis of a classification model. The processor calculates damage received by the work machine at each time on the basis of a plurality of pieces of operation information. The processor stores a database obtained by associating time, the classification ID, and the damage with each other. The processor calculates a representative value of the damage of each classification ID on the basis of the database, generates a sentence representing an operating state of a work machine corresponding to the classification ID by connecting word phrases corresponding to the magnitude of a plurality of feature amounts constituting a representative feature vector of the classification ID, and outputs to the output device operation information obtained by associating the sentence with the representative value of the damage calculated for the classification ID linked to the representative feature vector used to generate the sentence.SELECTED DRAWING: Figure 2 【課題】作業機械にダメージを与える動作状態を容易に知ることのできる装置を提供する。【解決手段】作業機械の動作状態算出装置は処理装置と出力装置を備える。処理装置は、稼働情報を特徴量とする特徴ベクトルを時刻毎に演算し、分類モデルに基づいて特徴ベクトルに分類IDを付与する。処理装置は、複数の稼働情報に基づいて、作業機械が受けたダメージを時刻毎に演算する。処理装置は、時刻、分類ID及びダメージを紐付けたデータベースを記憶する。処理装置は、データベースに基づいて、分類ID毎のダメージの代表値を演算し、分類IDの代表特徴ベクトルを構成する複数の特徴量の大きさに対応する語句を繋ぐことにより、分類IDに対応する作業機械の動作状態を表す文を生成し、その文と、その文の生成に用いた代表特徴ベクトルに紐付けられている分類IDに対して演算されたダメージの代表値と、を関連付けた動作情報を出力装置に出力する。【選択図】図2
