This is an important tool for the automatic analysis of textual data (open questions, litterature works, magazine articles, essays, etc.). The software Alceste can be used in Sociology, Psychology, Surveys processing, Speeches analysis, Advices in Marketing, Advertising, Journalism, History, Law, Linguistics, Medecine, Documentary research, Press analysis, and finally in the fields there are lots of texts to process. The aim is to quantify a text to extract its strongest significant structures so as to draw the essential information contained in teh textual data. Describe, classify, assimilate, synthesize automatically a text is the interest of ALCESTE.Ĭategory : Computer-Assisted Qualitative Data Analysis Software Reinert) that these structures are closely linked to the distribution of the words in a text and that this distribution is rarely done at random. Source : An early prototype of ATLAS.ti was developed as part of the ATLAS Project (1989-1992) at the Technical University of Berlin. In 1993, Thomas Muhr released the first commercial version of ATLAS.ti, marking the beginnings of Scientific Software Development, now ATLAS.ti GmbH. Summary : ATLAS.ti is a powerful workbench for the qualitative analysis of large bodies of textual, graphical, audio and video data. It offers a variety of tools for accomplishing the tasks associated with any systematic approach to "soft" data-i.e., material which cannot be analyzed by formal, statistical approaches. Product: Atlas.ti Developer: Thomas Muhr Developer Site: Platform: Windows 95, Windows 98, Windows NT 4.0 Price: $395.00 (Educational-Single Copy) $715.00 (Standard- Single Copy) $1,580.00 (Educational-5 Pack) $2,860.00 (Standard-5 Pack) $1,440.00 (Educational Workstation-Qty. #Atlasti download mac trial#ĥ) Scope: Text, digital Audio and Video Analysis Free Trial Download: Ĭhristopher Collins, Sheelagh Carpendale and Gerald PennĭocuBurst is the first visualization of document content which takes advantage of the human-created structure in lexical databases. The authors used an accepted design paradigm to generate visualizations which improve the usability and utility of WordNet as the backbone for document content visualization. The techniques can be generalized to multiple documents.Ī radial, space-filling layout of hyponymy (IS-A relation) is presented with interactive techniques of zoom, filter, and details-on-demand for the task of document visualization. To use DocuBurst, a user loads a document of interest into the visualization, and chooses a WordNet node at which to root the visualization. Below, we see that "idea" was chosen to root the visualization, and the occurrences of concepts that fall under "idea" appear in the visualization. The gold coloured nodes indicate search results for nodes matching 'pl' at the beginning. The visualization can be used to drill down into the loaded document. A paragraph browser, with a fish-eye lens, at the right of the DocuBurst display shows which paragraphs in the document from beginning to end (top to bottom) contain the selected node. #Atlasti download mac full#īy clicking any of the paragraph numbers the full text of that paragraph is shown in the details window, with occurrences of the selected node highlighted in the text. Or see this description : a new data visualization method for representing document content by a radial space filling layout technique. "docuburst" aims to provide a more intuitive abstraction than those developed through statistical techniques.the root node is shown as a circle. highly coloured nodes have many occurrences, while almost transparent nodes have few occurrences.Īll other nodes are assigned to a sector of an annulus with angular width which is part of the parent node’s width, depending on the amount of word occurrences. Transana is software for professional researchers who want to analyze digital video or audio data.
