This study proposes a methodology for inferring the bike trip purpose based on bike-share and point-of-interest (POI) data. Because the purpose of a trip involves decision-making, its inference necessitates an understanding of the spatiotemporal complexity of human activities. Thus, the spatiotemporal features affecting bike trips were selected from the bike-share data, and the land uses at the origin and destination of the trips were extracted from the POI data. During POI type embedding, the data were augmented considering the geographical distance between the POIs and the number of bike rentals at each bike station. We further developed a ground truth data construction method that uses temporal mobile and POI data. The inference model was built using machine learning and applied to experiments involving bike stations in Seocho-gu, Seoul, Korea. The experimental results revealed that optimal performance was achieved with the use of decision tree algorithms, as demonstrated by a 78.95% overall accuracy and 66.43% F1-score. The proposed method contributes to a better understanding of the causes of movement within cities.<\/jats:p>","DOI":"10.3390\/ijgi10050352","type":"journal-article","created":{"date-parts":[[2021,5,20]],"date-time":"2021-05-20T06:13:45Z","timestamp":1621491225000},"page":"352","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Public Bike Trip Purpose Inference Using Point-of-Interest Data"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8459-0260","authenticated-orcid":false,"given":"Jiwon","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Civil and Environmental Engineering, Seoul National University, Seoul 08826, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyun","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of Civil and Environmental Engineering, Seoul National University, Seoul 08826, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3618-4924","authenticated-orcid":false,"given":"Jiyoung","family":"Kim","sequence":"additional","affiliation":[{"name":"Social Eco Tech Institute, Konkuk University, Seoul 05029, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1231","DOI":"10.1007\/s11067-017-9366-x","article-title":"Exploring Bikesharing Travel Patterns and Trip Purposes Using Smart Card Data and Online Point of Interests","volume":"17","author":"Bao","year":"2017","journal-title":"Netw.
