| 总结: | This paper presents a cross-cultural crowdsourcing platform, called <i>OurPlaces</i>, where people from different cultures can share their spatial experiences. We built a three-layered architecture composed of: (<i>i</i>) places (locations where people have visited); (<inline-formula><math display="inline"><semantics><mrow><mi>i</mi><mi>i</mi></mrow></semantics></math></inline-formula>) cognition (how people have experienced these places); and (<inline-formula><math display="inline"><semantics><mrow><mi>i</mi><mi>i</mi><mi>i</mi></mrow></semantics></math></inline-formula>) users (those who have visited these places). Notably, cognition is represented as a paring of two similar places from different cultures (e.g., Versailles and Gyeongbokgung in France and Korea, respectively). As a case study, we applied the <i>OurPlaces</i> platform to a cross-cultural tourism recommendation system and conducted a simulation using a dataset collected from TripAdvisor. The tourist places were classified into four types (i.e., hotels, restaurants, shopping malls, and attractions). In addition, user feedback (e.g., ratings, rankings, and reviews) from various nationalities (assumed to be equivalent to cultures) was exploited to measure the similarities between tourism places and to generate a cognition layer on the platform. To demonstrate the effectiveness of the <i>OurPlaces</i>-based system, we compared it with a Pearson correlation-based system as a baseline. The experimental results show that the proposed system outperforms the baseline by 2.5% and 4.1% in the best case in terms of MAE and RMSE, respectively.
