TexTonic visualizes hierarchical clusters of representative terms, snippets, and documents in a single, multi-scale spatial layout. Exploration is supported by interacting with the visualization and directly manipulating the terms in the visualization using semantic interactions. These semantic interactions steer the underlying analytic model by translating user interactions within the visualization to contextual updates to the supporting data model. The combination of semantic interactions and information visualization at multiple levels of the data hierarchy helps users manage information overload so that they can more effectively explore very large text collections. In this article, we describe TexTonic\u2019s data processing and analytic pipeline, user interface and interaction design principles, and results of a user study conducted mid-development with experienced data analysts. We also discuss the implications TexTonic could have on visual exploration and discovery tasks.<\/jats:p>","DOI":"10.1177\/1473871618785390","type":"journal-article","created":{"date-parts":[[2018,7,12]],"date-time":"2018-07-12T10:10:55Z","timestamp":1531390255000},"page":"339-356","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["TexTonic: Interactive visualization for exploration and discovery of very large text collections"],"prefix":"10.1177","volume":"18","author":[{"given":"Celeste Lyn","family":"Paul","sequence":"first","affiliation":[{"name":"US Department of Defense, Laurel, MD, USA"}]},{"given":"Jessica","family":"Chang","sequence":"additional","affiliation":[{"name":"US Department of Defense, Laurel, MD, USA"}]},{"given":"Alex","family":"Endert","sequence":"additional","affiliation":[{"name":"Georgia Institute of Technology, Atlanta, GA, USA"}]},{"given":"Nick","family":"Cramer","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]},{"given":"David","family":"Gillen","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]},{"given":"Shawn","family":"Hampton","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]},{"given":"Russ","family":"Burtner","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]},{"given":"Ralph","family":"Perko","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]},{"given":"Kristin A","family":"Cook","sequence":"additional","affiliation":[{"name":"Pacific Northwest National Laboratory, Richland, WA, USA"}]}],"member":"179","published-online":{"date-parts":[[2018,7,12]]},"reference":[{"key":"bibr1-1473871618785390","volume-title":"Illuminating the path: the research and development agenda for visual analytics","author":"Thomas JJ","year":"2005"},{"key":"bibr2-1473871618785390","first-page":"473","volume-title":"Proceedings of the 2012 SIGCHI conference on human factors in computing systems","author":"Endert A"},{"key":"bibr3-1473871618785390","doi-asserted-by":"publisher","DOI":"10.1109\/38.974518"},{"key":"bibr4-1473871618785390","first-page":"42","volume-title":"Proceedings of the IEEE conference on information visualization","author":"Risch JS"},{"key":"bibr5-1473871618785390","first-page":"131","volume-title":"Proceedings of the 2011 IEEE Pacific visualization symposium","author":"Alsakran J"},{"key":"bibr6-1473871618785390","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2016.2598447"},{"key":"bibr7-1473871618785390","doi-asserted-by":"publisher","DOI":"10.1109\/TVCG.2016.2598445"},{"key":"bibr8-1473871618785390","first-page":"201","volume-title":"Proceedings of the 2010 IEEE Pacific visualization symposium","author":"Gansner ER"},{"key":"bibr9-1473871618785390","doi-asserted-by":"publisher","DOI":"10.1023\/A:1008690008856"},{"key":"bibr10-1473871618785390","doi-asserted-by":"publisher","DOI":"10.1016\/0306-4573(93)90024-8"},{"key":"bibr11-1473871618785390","unstructured":"Feinberg J.
