Abstract: A method for identifying documents that are similar in content to an input document includes receiving a request for identifying similar documents from among a plurality of candidate documents, retrieving document classification attributes for the input document and the candidate documents, where the document classification attributes are document level attributes.

Abstract: Systems, methods, and software are disclosed herein for facilitating enhanced canvas presentation environments. In an implementation, a user interacts with a touch-enabled display system capable of displaying items on a canvas. In response to a gesture made by the user with respect to an item being displayed, a format-specific interaction model is identified based on a format associated with the item. A response to the gesture may then be determined using the interaction model and the response rendered for display.

Abstract: Technology is disclosed herein that enhances communication and collaboration at a distance. In an implementation, a portal engine provides a communication and content portal through which users situated in different locations may interact and collaborate with each other. The portal includes an always-on, bi-directional video link through which the users may communicate over video. The portal may also include a digital white-board or other surface link over which shared content may be exchanged.

Abstract: Disclosed herein are systems, methods, and software to enhance avatar technology. An avatar engine identifies a session profile to apply to an avatar session when evaluating user actions generated by a user for potential expression in avatar actions associated with an avatar. The engine evaluates the user actions to determine if the user actions agree with the session profile for the avatar session. When the user actions do agree, they may be expressed through the avatar. For at least a user action that does not agree with the session profile for the avatar session, the avatar is driven to express a modified version of the user action that does agree with the session profile.

Abstract: Implementations disclosed herein include systems, methods, and software for enhanced presentations. In at least one implementation, motion information is generated that is associated with motion of a subject captured in three dimensions from a top view perspective of the subject. A control is identified based at least in part on the motion information and a presentation of information is rendered based at least in part on the control.
