This spatial significance has implications in various applications, trend detection being one of them. In this paper we propose a new algorithmic tool,\n            <jats:italic>GeoScope<\/jats:italic>\n            , to detect geo-trends.\n            <jats:italic>GeoScope<\/jats:italic>\n            is a data streams solution that detects correlations between topics and locations in a sliding window, in addition to analyzing topics and locations independently.\n            <jats:italic>GeoScope<\/jats:italic>\n            offers theoretical guarantees for detecting all trending correlated pairs while requiring only sub-linear space and running time. We perform various human validation tasks to demonstrate the value of\n            <jats:italic>GeoScope.<\/jats:italic>\n            The results show that human judges prefer\n            <jats:italic>GeoScope<\/jats:italic>\n            to the best performing baseline solution 4:1 in terms of the geographical significance of the presented information. As the Twitter analysis demonstrates,\n            <jats:italic>GeoScope<\/jats:italic>\n            successfully filters out topics without geo-intent and detects various local interests such as emergency events, political demonstrations or cultural events. Experiments on Twitter show that\n            <jats:italic>GeoScope<\/jats:italic>\n            has perfect recall and near-perfect precision.\n          <\/jats:p>","DOI":"10.14778\/2732240.2732242","type":"journal-article","created":{"date-parts":[[2015,5,12]],"date-time":"2015-05-12T15:37:52Z","timestamp":1431445072000},"page":"229-240","source":"Crossref","is-referenced-by-count":40,"title":["GeoScope"],"prefix":"10.14778","volume":"7","author":[{"given":"Ceren","family":"Budak","sequence":"first","affiliation":[{"name":"Microsoft Research"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodore","family":"Georgiou","sequence":"additional","affiliation":[{"name":"University of California, Santa Barbara"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Divyakant","family":"Agrawal","sequence":"additional","affiliation":[{"name":"University of California, Santa Barbara"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amr","family":"El Abbadi","sequence":"additional","affiliation":[{"name":"University of California, Santa Barbara"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2013,12]]},"reference":[{"key":"e_1_2_1_1_1","first-page":"1410","volume-title":"VLDB '07","author":"Bansal N.","year":"2007"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.14778\/2021017.2021022"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbi.2006.11.003"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.5555\/646255.684566"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/1871437.1871535"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.1145\/1061318.1061325"},{"key":"e_1_2_1_7_1","doi-asserted-by":"publisher","DOI":"10.1145\/1135777.1135949"},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.5555\/647912.740658"},{"key":"e_1_2_1_9_1","first-page":"1277","volume-title":"EMNLP '10","author":"Eisenstein J.","year":"2010"},{"key":"e_1_2_1_10_1","doi-asserted-by":"publisher","DOI":"10.1037\/h0031619"},{"key":"e_1_2_1_11_1","volume-title":"Brithis Medical Journal","author":"Gardner M.","year":"1995"},{"key":"e_1_2_1_12_1","volume-title":"WWE","author":"Glance N.
