Journal of Spatial Information Science, 2020(20), pp. 51–55.1948-660Xhttps://hdl.handle.net/10877/12143This vision paper summaries the methods of using social media data (SMD) to measure urban perceptions. We highlight two major types of data sources (i.e., texts and imagery) and two corresponding techniques (i.e., natural language processing and computer vision). Recognizing the data quality issues of SMD, we propose three criteria for improving the reliability of SMD-based studies. In addition, integrating multi-source data is a promising approach to mitigating the data quality problems.Text6 pages1 file (.pdf)enurban perceptionsplacedata qualitynatural language processingcomputer visionsocial media dataGeography and Environmental StudiesArticle© 2020 The Authors.https://doi.org/10.5311/JOSIS.2020.20.665This work is licensed under a Creative Commons Attribution 3.0 Unported License.
