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. The method also includes comparing the document classification attributes of the input document with classification attributes of the candidate documents to identify a subset of the candidate documents having matching document classification attributes, retrieving semantic entities from the input document and from candidate documents in the subset, pairwise comparing the semantic entity attribute of the input document with the semantic entity attribute of the candidate documents in the subset to identify semantic entities having matching semantic attributes, calculating a content similarity score between the semantic entity of the input document and the semantic entity of the candidate document in the subset, calculating a total similarity score for the candidate documents in the subset based on the content similarity score, a number of matching document classification attributes, and weight factors, and selecting similar documents from the subset based on the total similarity score.

System and method of determining content similarity by comparing semantic entity attributes

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.

Enhanced canvas environments

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.
