TAILIEUCHUNG - Báo cáo khoa học: "ConsentCanvas: Automatic Texturing for Improved Readability in EndUser License Agreements"

We present ConsentCanvas, a system which structures and “texturizes” End-User License Agreement (EULA) documents to be more readable. The system aims to help users better understand the terms under which they are providing their informed consent. ConsentCanvas receives unstructured text documents as input and uses unsupervised natural language processing methods to embellish the source document using a linked stylesheet. | ConsentCanvas Automatic Texturing for Improved Readability in EndUser License Agreements Oliver Schneider Alex Garnett Department of Computer Science University of British Columbia 201-2366 Main Mall Vancouver BC Canada V6T 1Z4 oschneid@ axfelix@ Abstract We present ConsentCanvas a system which structures and texturizes End-User License Agreement EULA documents to be more readable. The system aims to help users better understand the terms under which they are providing their informed consent. ConsentCanvas receives unstructured text documents as input and uses unsupervised natural language processing methods to embellish the source document using a linked stylesheet. Unlike similar usable security projects which employ summarization techniques our system preserves the contents of the source document minimizing the cognitive and legal burden for both the end user and the licensor. Our system does not require a corpus for training. 1 Introduction Less than 2 of users read End-User License Agreement EULA documents when indicating their consent to the software installation process Good et al. 2007 . While these documents often serve as a user s sole direct interaction with the legal terms of the software they are usually not read as they are presented in such a way as is divorced from the use of the software itself Friedman et al. 2005 . To address this Kay and Terry 2010 developed what they call Textured Consent agreements which employ a linked stylesheet to augment salient parts of a EULA document. Unlike summarization-driven approaches to usable security this is achieved without any modification of the underlying text minimizing the cognitive and legal burden for both the end user and the licensor and removing the need to make available a supplementary unmodified document Kelley et al 2009 Far-zindar 2004 . We have developed a system ConsentCanvas for automating the creation of a Textured Consent document from an unstructured EULA based on the .
