These posts collectively contain a wealth of insights into how masses perceive their surroundings. Therefore, extracting people's perceptions from social media posts can provide valuable information about pertinent issues such as public transportation, emergency conditions, and even reactions to political actions or other activities. This paper proposes a novel approach to extract such perceptions from a corpus of social media posts originating from a given broad geographical region. The approach divides the broad region into a number of sub-regions, and trains language models over social media conversations within these sub-regions. Using Bayesian and geo-smoothing methods, the ensemble of language models can be queried with phrases embodying a perception. Discrete and continuous visualization methods represent the extent to which social media posts within the sub-regions express the query. The capabilities of the perception mining approach are illustrated using transportation-themed scenarios. <\/jats:p>","DOI":"10.1142\/s0218194014400129","type":"journal-article","created":{"date-parts":[[2015,3,9]],"date-time":"2015-03-09T09:02:41Z","timestamp":1425891761000},"page":"1273-1299","source":"Crossref","is-referenced-by-count":1,"title":["Discovering Perceptions in Online Social Media: A Probabilistic Approach"],"prefix":"10.1142","volume":"24","author":[{"given":"Derek","family":"Doran","sequence":"first","affiliation":[{"name":"Department of Computer Science &amp; Engineering, Kno.e.sis Research Center, Wright State University, Dayton OH 45435, USA"}]},{"given":"Swapna S.","family":"Gokhale","sequence":"additional","affiliation":[{"name":"Department of Computer Science &amp; Engineering, University of Connecticut, Storrs CT 06269, USA"}]},{"given":"Aldo","family":"Dagnino","sequence":"additional","affiliation":[{"name":"Industrial Software Systems, Data Analytics, ABB Corporate Research, 940 Main Campus Drive, Raleigh NC 27603, USA"}]}],"member":"219","published-online":{"date-parts":[[2015,3,9]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-947X(2004)130:1(94)"},{"key":"rf3","doi-asserted-by":"publisher","DOI":"10.1109\/TPAMI.1983.4767370"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1177\/016001700761012710"},{"key":"rf7","first-page":"322","author":"Burns A.","year":"2009","journal-title":"Communications Policy & Research Forum"},{"key":"rf9","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9364(2000)126:2(105)"},{"key":"rf10","doi-asserted-by":"publisher","DOI":"10.1016\/j.cag.2013.10.008"},{"key":"rf17","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-29262-0_8"},{"key":"rf20","volume-title":"Still stuck in traffic: Coping with peak-hour traffic congestion","author":"Downs A.","year":"2004"},{"key":"rf21","doi-asserted-by":"publisher","DOI":"10.1145\/1961209.1961211"},{"key":"rf22","doi-asserted-by":"publisher","DOI":"10.1049\/ip-vis:19952064"},{"key":"rf23","doi-asserted-by":"publisher","DOI":"10.1109\/MIS.2011.52"},{"key":"rf24","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-947X(2006)132:4(331)"},{"key":"rf25","first-page":"38","volume":"1509","author":"Ha T.-J.","year":"1995","journal-title":"Transportation Research Record"},{"key":"rf28","doi-asserted-by":"publisher","DOI":"10.3141\/2169-05"},{"key":"rf32","doi-asserted-by":"publisher","DOI":"10.1061\/(ASCE)0733-9364(2007)133:2(105)"},{"key":"rf35","doi-asserted-by":"publisher","DOI":"10.1016\/j.tranpol.2010.04.009"},{"key":"rf36","first-page":"31","volume":"5","author":"Lotan G.","year":"2011","journal-title":"Int.
