A data processing system for delivering an open profile personalization system based profile data structures that contain one or more interest nodes. The interest nodes include respective sets of targets and qualifiers, where the targets and qualifiers comprise typed-attributes to be used in the filtering of information files for delivery as a result set for the interest nodes. Targets and qualifiers are applied the typed-attributes of available information files to produce the filtered set. Web pages showing the personalized results include tools based on sophisticated content analysis to assist the user in creation and editing of the open profile. A method for presenting and updating the web pages is responsive to the use of these tools.

Information display system based on user profile data with assisted and explicit profile modification

In accordance with one aspect of the present invention, disclosed is an image analysis and conversion method and system, where digital ink images are converted to structured object representations of the digital ink images, capable of being edited by a structured text/graphics editor.

Method and apparatus to convert digital ink images for use in a structured text/graphics editor

An image analysis and conversion method and system. Bitmapped ink images are converted to structured object representations of the bitmapped images, which may be read and edited by a structured text/graphics editor. The structured object representations correlate to perceptually salient areas of the bitmapped images. The structured object representations are editable by the structured text/graphics editor to allow a user to generate alternative interpretations of the bitmapped images.

A print management system includes a policy that determines a protection level for a document to be printed. The document is printed using forgery detection and deterrence technologies, such as fragile and robust watermarks, glyphs, and digital signatures, that are appropriate to the level of protection determined by the policy. A plurality of printers are managed by a print management system. Each printer can provide a range of protection technologies. The policy determines the protection technologies for the document to be printed. The print management system routes the print job to a printer that can apply the appropriate protections and sets the appropriate parameters in the printer. Copy evidence that can establish that a document is a forgery and/or tracing information that identifies the custodian of the document and restrictions on copying of the document and use of the information in the document are included in the watermark that is printed on the document. A document can be verified as an original or established as a forgery by inspecting the copy evidence and/or tracing information in the watermark.

A system and method for receiving, analyzing, and managing a database of calendar information obtained from a variety of source documents. Information derived and extracted from calendar documents is used establish a database of events. Extraction of relevant information from the calendar documents is facilitated by guidance in the form of user input, document templates, or other specification of the structure and content of the calendar documents.

Distributed document-based calendaring system

A system and method for receiving, analyzing, and managing key information extracted from input documents in multiple document genres. A document &ldquo;genre&rdquo; is the social environment that defines the document's expected structure and content. Information is extracted from the input documents based on their genre, and is synthesized into a distributed genre document, or database, representing all extracted information from all input documents. An output document having a selected genre is created by assembling information from the database consistent with the selected genre.

Dynamic content database for multiple document genres

A display array element including a substrate, a prism rotatable relative to the substrate, and a fluid conduit defined in part by the substrate. The prism has a first viewable surface having fist reflectance characteristics and a second viewable surface having second reflectance characteristics. The fluid conduit permits direction of fluid against the prism to rotate the prism to selectively allow viewing of one of the first and second viewable surfaces.

A system for automatically generating indexes for handwritten notes captured as digital ink in a computer is disclosed. Ink words are identified, and features of the ink words are computed. Pairwise distances or match scores, which measure the distance in the features between two ink words, are calculated. A clustering technique selects equivalence classes of ink words. Index terms, which are non-uniform through-out the notes, are selected from the equivalence classes of ink words. The system generates an index from the index terms, including displaying pages numbers where the index terms are located in the notes as well as hyper-linking the index terms. A technique to identify a threshold for use in clustering the ink words is also disclosed.

A search and recommendation system employs the preferences and profiles of individual users and groups within a community of users, as well as information derived from shared document bookmarks, to augment Internet searches, re-rank search results, and provide recommendations for documents based on a subject-matter query. The search and recommendation system operates in the context of a shared bookmark manager, which stores individual users' bookmarks (some of which may be published or shared for group use) on a centralized bookmark database connected to the Internet. The shared bookmark manager is implemented as a distributed program, portions of which operate on users' terminals and other portions of which operate on the centralized bookmark database.

A bistable flap array display in which flaps selectively cover portions of a background substrate in response to fluid flow and a flap catchment mechanism, each flap rendering at least one pixel of the display. The catchment mechanism can be electrostatically based and the fluid can reduce the charge required to operate the catchment mechanism by creating a partial vacuum that lifts the flaps until the flow can impinge on the flap directly.

A processor measures skew of lines in an image by obtaining a first, coarse approximation to skew direction and then using the first approximation to obtain a second, fine approximation that is more precise than the first. A third, even more precise approximation can be obtained using the second approximation, and further successive approximations can be similarly obtained. In an image of text, the first approximation can be obtained by finding the direction in which characters are closest together, since intercharacter distances are typically smaller than interline distances. This direction can be determined by measuring distances from selected pixels at edges of connected components across white pixels to edges of other connected components. The measured distances in each direction can be combined to obtain a central value for the direction, such as an average. The central values form a profile indicating central value as a function of direction. The minima separated by 180&deg; within the profile indicate the direction of intercharacter spacing, which provides a first approximation of the skew direction. Alternatively, the first approximation can be obtained by finding a direction that has the largest variance in black pixels per line, because the lines in the direction of skew either have many black pixels due to characters in a line or few black pixels due to spaces between lines. The second approximation can then be obtained by determining which one of a number of directions close to the first approximation has the largest variance in black pixels per line. The range of directions used to obtain the second approximation can be based on the angle separating directions used in obtaining the first approximation.
