In the paper, we first discuss the rules to distinguish false detection events in RFID object trajectories. Then, as a unified cleaning framework, we establish a probabilistic region connection graph to represent region detection features, region connection relationships, and region transition probabilities between neighboring physical regions. Focusing on interpolating the missing events, we suggest two path-based probabilistic cleaning strategies, namely, the Most Likely Path (MLP) strategy and the Highest Weighting Probability Path (HWPP) strategy.<\/jats:p>","DOI":"10.1145\/3124104.3124107","type":"journal-article","created":{"date-parts":[[2017,7,13]],"date-time":"2017-07-13T20:02:09Z","timestamp":1499976129000},"page":"3-10","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Probabilistic cleaning over trajectory events of mobile RFID objects"],"prefix":"10.1145","volume":"9","author":[{"given":"Guoqiong","family":"Liao","sequence":"first","affiliation":[{"name":"Jiangxi University of Finance &amp; Economics, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Philip S.","family":"Yu","sequence":"additional","affiliation":[{"name":"University of Illinois at Chicago"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qianhui","family":"Zhong","sequence":"additional","affiliation":[{"name":"University of Oulu, PL, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sihong","family":"Xie","sequence":"additional","affiliation":[{"name":"Lehigh University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changxuan","family":"Wan","sequence":"additional","affiliation":[{"name":"Jiangxi University of Finance &amp; Economics, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dexi","family":"Liu","sequence":"additional","affiliation":[{"name":"Jiangxi University of Finance &amp; Economics, Nanchang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2017,7,13]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1401890.1551566"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2442968.2442971"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.5555\/2514943.2515388"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/11687238_40"},{"volume-title":"Proceeding of the 5th International Conference on Advanced Geographic Information Systems, Applications and Services. 2013:  125--132","author":"Al-Serafi A.","key":"e_1_2_1_5_1","unstructured":"A.
