飲食店向け不動産物件の賃料は,不動産会社のベテラン営業職員が培ってきた経験や勘といった暗黙知に基づいて決定されている.賃料の決定要因としては,物件固有の情報である静的情報,物件周辺の情報である動的情報,物件の特徴などを含む潜在的情報が挙げられている.潜在的情報は,ベテラン営業職員による指標化が難しいとされる情報である.本研究では潜在的情報として,物件に付与されているキャッチコピーを用いる手法を提案する.キャッチコピーはDoc2Vec によりベクトル表現に変換し,ノイズを除去するため,品詞の選別を行なった.その結果,品詞の選別を行うことで推定精度が向上し,重回帰分析を用いた場合に,決定係数が0.611 と最も高い値が得られた.

Objective: In various fields, differences in eye-gazing patterns during tasks between experts and novices have been evaluated. The aim of this study was to investigate gazing patterns during neuro-endovascular treatment using an eye-tracking device and assess whether gazing patterns depend on the physician’s experience or skill.Methods: Seven physicians performed coil embolization for a cerebral aneurysm in a silicone vessel model under biplane X-ray fluoroscopy, and their gazing patterns were recorded using an eye-tracking device. The subjects were divided into three groups according to experience, highly experienced (Expert) group, intermediately experienced (Trainee) group, and less experienced (Novice) group. The duration of fixation on the anterior–posterior (AP) view screen, lateral (LR) view, and out-of-screen were compared between each group.Results: During microcatheter navigation, the Expert and Trainee groups spent a long time on fixation to AP, while the Novice group split their attention between each location. In coil insertion, the Expert group gazed at both the AP and the LR views with more saccades between screens. In contrast, the Trainee group spent most of their time only on the AP view screen and the Novice group spent longer out-of-screen.Conclusion: An eye-tracking device can detect different gazing patterns among physicians with several experiences and skill levels of neuroendovascular treatment. Learning the gazing patterns of experts using eye tracking may be a good educational tool for novices and trainees.

People under chronic stress cannot have appropriate care without self-reported health status. If their mental stress is quantitatively estimated with small sensors and data mining technologies, we can know their variation of mental state in their daily life. Sharing the information with others will help them not get worse. An application for smart phones which can check the variation of mental state as a life log is discussed in this paper.
