Year of Graduation: 2017

Today one can hardly imagine linguistics without digital corpora, which are widely used in various research. Since they propose fast and handy instruments for searching, a user can get a list of examples of her interest. While it is useful for professional use, sometimes it is also in need to demonstrate those results in an illustrative way. Recently, Gambette & Véronis 2010 presented TreeCloud – an instrument for visualizing a text in a form of a tree that reflects semantic proximity between the words. TreeCloud make it possible to visualize two levels of text information - ratio of word occurrences in a text as well as semantic relations between them. The original version of TreeCloud has several issues including high dependence on the external software, restriction on some operating systems and languages of the text input. In the present paper, we introduce upgraded version of TreeCloud visualization tool adopted for usage on Russian National Corpora, available as web-based application (http://1-dot-treecloud-web.appspot.com/), and as java desktop application with minimum dependencies (https://github.com/aleksandrachasch/treecloud).
