These geo-textual data cover a wide range of topics. Users are interested in receiving up-to-date geo-textual objects (e.g., geo-tagged Tweets) such that their locations meet users' need and their texts are interesting to users. For example, a user may want to be updated with tweets near her home on the topic \"dengue fever headache\".<\/jats:p>\n          <jats:p>\n            AB@In this demonstration, we present SOPS, the &lt;u&gt;S&lt;\/u&gt;patial-Keyw&lt;u&gt;o&lt;\/u&gt;rd &lt;u&gt;P&lt;\/u&gt;ublish\/&lt;u&gt;S&lt;\/u&gt;ubscribe System, that is capable of efficiently processing spatial keyword continuous queries. SOPS supports two types of queries: (1) &lt;u&gt;B&lt;\/u&gt;oolean &lt;u&gt;R&lt;\/u&gt;ange &lt;u&gt;C&lt;\/u&gt;ontinuous (BRC) query that can be used to subscribe the geo-textual objects satisfying a boolean keyword expression and falling in a specified spatial region; (2) &lt;u&gt;T&lt;\/u&gt;empor&lt;u&gt;a&lt;\/u&gt;l &lt;u&gt;S&lt;\/u&gt;patial-&lt;u&gt;K&lt;\/u&gt;eyword Top-\n            <jats:italic>k<\/jats:italic>\n            Continuous (TaSK) query that continuously maintains up-to-date top-\n            <jats:italic>k<\/jats:italic>\n            most relevant results over a stream of geo-textual objects. SOPS enables users to formulate their queries and view the real-time results over a stream of geo-textual objects by browser-based user interfaces. On the server side, we propose solutions to efficiently processing a large number of BRC queries (tens of millions) and TaSK queries over a stream of geo-textual objects.\n          <\/jats:p>","DOI":"10.14778\/2733004.2733040","type":"journal-article","created":{"date-parts":[[2015,5,12]],"date-time":"2015-05-12T15:37:52Z","timestamp":1431445072000},"page":"1601-1604","source":"Crossref","is-referenced-by-count":24,"title":["SOPS"],"prefix":"10.14778","volume":"7","author":[{"given":"Lisi","family":"Chen","sequence":"first","affiliation":[{"name":"Nanyang Technological University, Singapore"}]},{"given":"Yan","family":"Cui","sequence":"additional","affiliation":[{"name":"Nanyang Technological University, Singapore"}]},{"given":"Gao","family":"Cong","sequence":"additional","affiliation":[{"name":"Nanyang Technological University, Singapore"}]},{"given":"Xin","family":"Cao","sequence":"additional","affiliation":[{"name":"Nanyang Technological University, Singapore"}]}],"member":"320","published-online":{"date-parts":[[2014,8]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/2463676.2465328"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1145\/2487575.2487617"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1145\/956863.956951"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.5555\/1394399"},{"key":"e_1_2_1_6_1","doi-asserted-by":"publisher","DOI":"10.14778\/2536336.2536340"}],"container-title":["Proceedings of the VLDB Endowment"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.14778\/2733004.2733040","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,12,28]],"date-time":"2022-12-28T09:42:43Z","timestamp":1672220563000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.14778\/2733004.2733040"}},"subtitle":["a system for efficient processing of spatial-keyword publish\/subscribe"],"short-title":[],"issued":{"date-parts":[[2014,8]]},"references-count":5,"journal-issue":{"issue":"13","published-print":{"date-parts":[[2014,8]]}},"alternative-id":["10.14778\/2733004.2733040"],"URL":"https:\/\/doi.org\/10.14778\/2733004.2733040","relation":{},"ISSN":["2150-8097"],"issn-type":[{"value":"2150-8097","type":"print"}],"subject":[],"published":{"date-parts":[[2014,8]]}}}
