A range of visualization types and control mechanisms to support knowledge discovery are presented. These include corpus- and document-specific views, iterative topic modeling, search, and visual filtering. Drill-down functionality is provided to allow analysts to visualize individual document sections and their relations within the global topic space. Analysts can search across a dataset through a set of expansion techniques on selected document and topic nodes. Furthermore, analysts can select relevant subsets of documents and perform real-time topic modeling on these subsets to interactively visualize topics at various levels of granularity, allowing for a better understanding of the documents. A discussion of the design and implementation choices for each visual analysis technique is presented. This is followed by a discussion of three diverse use cases in which TopicNets enables fast discovery of information that is otherwise hard to find. These include a corpus of 50,000 successful NSF grant proposals, 10,000 publications from a large research center, and single documents including a grant proposal and a PhD thesis.\n          <\/jats:p>","DOI":"10.1145\/2089094.2089099","type":"journal-article","created":{"date-parts":[[2012,10,12]],"date-time":"2012-10-12T20:56:02Z","timestamp":1350075362000},"page":"1-26","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":81,"title":["TopicNets"],"prefix":"10.1145","volume":"3","author":[{"given":"Brynjar","family":"Gretarsson","sequence":"first","affiliation":[{"name":"University of California Santa Barbara"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"O\u2019Donovan","sequence":"additional","affiliation":[{"name":"University of California Santa Barbara"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlin","family":"Bostandjiev","sequence":"additional","affiliation":[{"name":"University of California Santa Barbara"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tobias","family":"H\u00f6llerer","sequence":"additional","affiliation":[{"name":"University of California Santa Barbara"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arthur","family":"Asuncion","sequence":"additional","affiliation":[{"name":"University of California Irvine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Newman","sequence":"additional","affiliation":[{"name":"University of California Irvine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Padhraic","family":"Smyth","sequence":"additional","affiliation":[{"name":"University of California Irvine"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,2]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"Analyzer M. 2010.
