PROBLEM TO BE SOLVED: To enhance the estimation accuracy of movement means estimation by enabling the extraction of a feature amount which acquires sequence changes of a feature of an individual positioning point from a GPS track.SOLUTION: A sequence expression extraction unit 30 extracts sequence expression having information, such as a movement time to each positioning point on the basis of GPS track segments stored in DBs 10, 20, and stores the sequence expression in DBs 40, 50. A sequence feature amount extraction model generation unit 60 generates a sequence feature amount extraction model on the basis of stored data of the DBs 40, 50, and stores the sequence feature amount extraction model in a DB 70. A sequence feature amount extraction unit 80 extracts a sequence feature amount by using the sequence feature amount extraction model of the DB 70, and stores the sequence feature amount in a DB 90. A feature amount connection unit 120 stores a connection feature amount obtained by connecting the conventional basic feature amount stored in a DB 110 and the sequence feature amount stored in the DB 90 in a DB 130. An estimation model generation unit 140 generates an estimation model on the basis of the stored data of the DB 130, and stores the estimation model in a DB 150.SELECTED DRAWING: Figure 1
【課題】GPS軌跡から個々の測位点の特徴の系列的な変化を捉えた特徴量を抽出可能とすることで移動手段推定の推定精度を高める。【解決手段】系列表現抽出部30は、DB10,20に格納されたGPS軌跡セグメントに基づき各測位点に対して移動時間などの情報を持たせた系列表現を抽出し、DB40,50に格納する。系列特徴量抽出モデル生成部60は、DB40,50の格納データに基づき系列特徴量抽出モデルを生成し、DB70に格納する。系列特徴量抽出部80は、DB70の系列特徴量抽出モデルを用いて系列特徴量を抽出し、DB90に格納する。特徴量連結部120は、DB110に格納された従来の基本特徴量と、DB90に格納された系列特徴量とを連結させた連結特徴量とをDB130に格納する。推定モデル生成部140は、DB130の格納データに基づき推定モデルを生成し、DB150に格納する。【選択図】図1
