Assessing the significance of spatiotemporal co-occurrences plays an important role in the spatiotemporal frequent pattern mining applications of moving region objects. A spatiotemporal version of the popular Jaccard measure has been used for measuring the strength of spatiotemporal co-occurrences. We will demonstrate the shortcomings of the Jaccard (\n            <jats:italic>J<\/jats:italic>\n            ) measure when it is used for assessing the significance of co-occurrences among spatiotemporal instances with highly different spatiotemporal evolution characteristics. We will present two extended novel measures (\n            <jats:italic>J<\/jats:italic>\n            <jats:sup>+<\/jats:sup>\n            and\n            <jats:italic>J<\/jats:italic>\n            <jats:sup>*<\/jats:sup>\n            ) that address the problems linked to the\n            <jats:italic>J<\/jats:italic>\n            measure. Our work includes algorithms for the significance measure calculations, the proofs and explanations about the key properties of measures, and a detailed experimental evaluation section. Our experiments include in-depth relevancy and running time analyses demonstrating the suitability of our proposed measures for spatiotemporal frequent pattern mining algorithms.\n          <\/jats:p>","DOI":"10.1145\/3139351","type":"journal-article","created":{"date-parts":[[2017,11,3]],"date-time":"2017-11-03T12:34:28Z","timestamp":1509712468000},"page":"1-35","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":9,"title":["Measuring the Significance of Spatiotemporal Co-Occurrences"],"prefix":"10.1145","volume":"3","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9799-9265","authenticated-orcid":false,"given":"Berkay","family":"Aydin","sequence":"first","affiliation":[{"name":"Georgia State University"}]},{"given":"Ahmet","family":"Kucuk","sequence":"additional","affiliation":[{"name":"Georgia State University"}]},{"given":"Rafal A.","family":"Angryk","sequence":"additional","affiliation":[{"name":"Georgia State University"}]},{"given":"Petrus C.","family":"Martens","sequence":"additional","affiliation":[{"name":"Georgia State University"}]}],"member":"320","published-online":{"date-parts":[[2017,11,2]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/170036.170072"},{"key":"e_1_2_2_2_1","volume-title":"Retrieved","author":"Aydin Berkay","year":"2016","unstructured":"Berkay Aydin . 2016 .
