They usually use techniques such as image processing, RFID devices, among others. Social network mining has emerged as a low-cost alternative. However, social networks come with several challenges such as informal language and misspellings. This paper proposes a method to extract traffic accident data from Twitter in Spanish. The method consists of four phases. The first phase establishes the data collection mechanisms. The second consists of vectorially representing the messages and classifying them as accidents or non-accidents. The third phase uses named entity recognition techniques to detect the location. In the fourth phase, locations pass through a geocoder that returns their geographic coordinates. This method was applied to Bogota city and the data on Twitter were compared with the official traffic information source; comparisons showed some influence of Twitter on the commercial and industrial area of the city. The results reveal how effective the information on accidents reported on Twitter can be. It should therefore be considered as a source of information that may complement existing detection methods.<\/jats:p>","DOI":"10.3390\/info13010026","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T23:35:09Z","timestamp":1641771309000},"page":"26","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Extraction and Analysis of Social Networks Data to Detect Traffic Accidents"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2628-1173","authenticated-orcid":false,"given":"Nestor","family":"Suat-Rojas","sequence":"first","affiliation":[{"name":"Programming Languages and Systems\u2014PLaS Research Group, Department of Systems and Industrial Engineering, Universidad Nacional de Colombia, Bogota 999076, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9113-1369","authenticated-orcid":false,"given":"Camilo","family":"Gutierrez-Osorio","sequence":"additional","affiliation":[{"name":"Programming Languages and Systems\u2014PLaS Research Group, Department of Systems and Industrial Engineering, Universidad Nacional de Colombia, Bogota 999076, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6687-1429","authenticated-orcid":false,"given":"Cesar","family":"Pedraza","sequence":"additional","affiliation":[{"name":"Programming Languages and Systems\u2014PLaS Research Group, Department of Systems and Industrial Engineering, Universidad Nacional de Colombia, Bogota 999076, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,10]]},"reference":[{"key":"ref_1","unstructured":"Cookson, G., and Pishue, B.
