碩士 === 國立臺灣科技大學 === 資訊管理系 === 106 === In the evolution of human-computer interface, modern desktop applications make use of the prevalent graphical user interfaces.It’s visually simpler, intuitive, and easier for users to work with. Icons are parts of the graphical user interfaces for a computer system. They are pictograms displayed on a computer screen in order to help a user navigate a computer system. In general, the same type of documents are often represented by the same icon, so it may lead to lots of identical icons that are not distinctive. As users can’t quickly recall the contents of the document from the icons so it will increase the time of retrieval. Our research provides a system which can automatically generate icons associated with a document’s context semantics. Firstly we find keywords through document contents analysis and retrieve the images of keywords. Next, we make use of saliency detection and image segmentation to extract the image foreground. Finally, the icon is generated from a image collage. The resulting icons can enhance the representation of files in a Graphical User Interface by providing semantically and graphically distinguishable symbols. In addition to icons, we also provide other presentations for documents. Using text analysis and sentiment analysis we present documents by auditory and visual information. Through our system, users can improve their associated memory and quickly evoke the contents of the documents by different feelings before the file is opened.
