Abstract: Various embodiments of this disclosure relate to digital documents and, more particularly, to facilitating active reading of one or more digital documents by creating dynamic project views of a virtual workspace. A virtual workspace includes a document and document objects associated with the document, where each document object can relate to a respective portion of the document. According to a method, a document object is tagged with a tag including a first value selected from a first category. A request is received for an automated arrangement of the document objects by the first category. The document object is assigned a first coordinate in a dimension of the virtual workspace, where the first coordinate is computed based on the first value in the tag. Based on the request, the document object is automatically repositioned within the virtual workspace to the first coordinate in the dimension.

Abstract: Review systems and methods facilitate active reading by providing a flexible environment in which users can examine documents. A review system may include a virtual workspace, a document view region, a preview region, and optional document objects. The virtual workspace may simulate a desktop or other physical workspace. The document objects may be created from one or more documents through tools of the review system. These document objects may be independently moveable throughout the virtual workspace as needed to facilitate the user's active reading process, and the document objects within a single workspace may refer to more than a single document. The review system may also include analytical tools enabling the user to analyze his and others' use of the tools as applied to selected documents.

Abstract: An image compression technique in which patterns identified, the means of separating the image components, the parameterization of the patterns, and the lower level numerical encodings are all designed around a narrow class of images, such as two-dimensional projections of three-dimensional visualizations of data generated by numerical weather simulations. The process analyzes an image in terms of perceptual constructs of the human visual system and searches for patterns among analyzed abstractions of the image. The image is then described in terms of the perceptual constructs and the patterns found among them. The image is re-represented by describing the image as a collection of parameterized versions of the patterns prevalent in that class of image. A resulting description is taken outside of the context of abstract patterns. Redundancies in the description are looked for and the data is re-represented so as to eliminate the redundancies and compress the description.
