Summary: | PROBLEM TO BE SOLVED: To provide a general-purpose data creation device for creating target data from start data.SOLUTION: A data creation device comprises: template creation means for dividing learning target data collected in advance into multiple event sentences describing an event, associating the event sentences with a prescribed item included in learning start data collected in advance, and then permuting prescribed elements included in the event sentences into generalization tags to generate event templates; learning means for performing learning of a prediction model for an event sequence with respect to a prescribed item sequence, based on the event templates and the learning start data; and target data creation means for predicting an event sequence from the sequence of the prescribed item included in the start data input based on the prediction model, and permuting the generalization tag included in the event sequence to a specific character string included in the input start data to generate target data.SELECTED DRAWING: Figure 3
【課題】出発データから目的データを作成する汎用的なデータ生成装置を提供すること【解決手段】データ生成装置は、予め収集された学習用目的データをイベントを記述するイベント文に分割し、このイベント文と予め収集された学習用出発データに含まれる所定の項目とを対応づけ、イベント文に含まれる所定の要素を汎化タグに置換してイベントテンプレートを生成するテンプレート生成手段と、イベントテンプレートと学習用出発データに基づいて所定の項目の系列に対するイベントの系列の予測モデルの学習を行う学習手段と、予測モデルに基づいて入力された出発データに含まれる所定の項目の系列からイベント系列を予測し、このイベント系列に含まれる汎化ダグを入力された出発データに含まれる具体的な文字列に置換して目的データを生成する目的データ生成手段を備える。【選択図】図3 |
