Abstract: A system redacts content in a multi-layered document by executing a content modifier process that redacts a first portion of content in a source layer and then automatically redacts related content in at least one target layer. The content modifier process overlays the source redaction region on corresponding areas of other layers in the document to identify target redaction regions in those other layers that contain target content. In turn, the content modifier process automatically identifies and redacts the target content within target redaction regions.

Abstract: A robust, lightweight, bottom-up segmentation method for Internet content. According to the present invention, individual segments are created based upon weights assigned according to document structure and markup elements and semantics. Smaller segments are then merged into larger segments by determining which portions of the content page are related to each other. The remaining segments are then intelligently divided based upon device constraints.

Abstract: Various technologies and techniques detect lists in vector graphics based documents and use them in meaningful ways. The system detects at least one list in a vector graphics based document using a set of rules. Pattern detection logic identifies characters, symbols, numbers, letters, and/or images that may start a list. Additional pattern detection logic determines if a list exists. The system can identify and parse bulleted lists, numbered or lettered lists, and nested lists that are any combination of both. Once identified, the content is translated into a modified format. The content can be output to a destination application in the modified format that is more suitable for output or use by the destination application.

Abstract: A mixed text and image layout algorithm capable of supporting Unicode text and arbitrary content definitions for geometric layout with worst case two-pass layout placement procedure. Layout of Unicode text requires a number of distinct processing steps commencing with classification of input characters into contiguous groups of identical directionality, writing system and possibly script (and language) followed by mapping of character groups to glyphs for display purposes followed by a layout taking into account font display characteristics, embedded directionality level and shape of container for layout contents. Layout is best-case achieved in a single layout pass and worst-case in two passes. During layout information is cached to facilitate incremental changes to an existing layout in order to minimize refresh operations for editing display purposes. An optional two-pass operation on the layout result may be used to generate ordered rendering operation to support so-called Z-index display.

Abstract: To correct at least one extraneous or missing space in a document, weights are assigned to tokens contained in a dictionary. Each token is defined by an ordered sequence of non-space symbols. The weights are assigned based on at least one of a token length and frequency of occurrence of the token in the document. Corrected text is generated from text of the document by applying an ordered sequence of symbol-level transformations selected from a group of symbol-level transformations including at least (i) deleting a space, (ii) inserting a space, and (iii) copying a symbol. The ordered sequence of symbol-level transformations is optimized respective to an objective function dependent upon the weights of tokens of the corrected text.

Abstract: A system and method is provided for enabling an electronic device to efficiently access information content. A server browser accesses the information content over a network. The accessed information content is retrieved and adapted for presentation for the electronic device. A serializer dynamically formats the adapted information content according to a client browser. The client browser receives and presents the information content on the electronic device. An event translator is included to provide additional compatibility with commercially available client browsers. The information content is formatted to selectively minimize the horizontal scrolling required to view the content. The need for horizontal scrolling is selectively removed where not necessary to preserve the context. Each component or sub-component of the original area, such as a frame, table row, table cell or nested table, is considered separately and may be preserved, resized, or replaced.

Abstract: Methods and apparatus for calculating paragraph layout. A method begins with a first node in a paragraph and calculates an optimal line break scheme for paragraph layout that ended in the node. For every subsequent node in the paragraph, the method calculates an optimal line break scheme for paragraph layout that ends respectively in every subsequent node. Each optimal line break scheme is calculated by minimizing the total of a penalty value of a current line and all preceding penalties of all preceding lines. The preceding penalties of all preceding lines are defined by a previously calculated optimal line break scheme.

Column minimum widths and column maximum widths may be selected to enhance user comprehension of data displayed in the table. Each column may be associated with a variable representing an order, and the columns may be resized in ascending sequence based on the order variable.

Abstract: A layout adjustment method for determining a layout of a page to be formed on a printing medium includes a generation step which generates a template including a plurality of partial areas, to which data are inserted, a setting step to set a link between two partial areas of the plurality of partial areas to connect the two partial areas, a first adjustment step to generate first layout indicating positions and sizes of the two partial areas, and a printing conditions setting step to set a binding margin for printing a document including the template. In addition, a correction step corrects the template on the basis of the binding margin set in the print conditions setting step, and a second adjustment step generates a second layout indicating the positions and the sizes of the two partial areas adjusted on the basis of the sizes of data to be inserted in the two partial areas and the template corrected in the correction step.

Abstract: One embodiment of the present invention provides a system that facilitates detecting white space tables within a document, wherein a white space table is comprised of text arranged in rows and columns, wherein at least some of the rows and columns are separated by bands of white space rather than by lines. The system operates by identifying an area that includes consecutive lines of text objects with an amount of white space between text objects greater than a specified value. Note that a text object is a string of text without an amount of white space greater than the specified value. The system then determines if the text objects on consecutive lines have widths that are within a specified tolerance of each other. If so, the system checks the spaces between the consecutive lines of text objects to determine if they belong to a single white space table or multiple white space tables.

Abstract: Architecture of one or more algorithms for autofitting objects with non-trivial geometries in documents. The algorithms autofit rectangular objects (such as floaters), when the objects contain both left and right aligned objects, autofit tables, determine correct sizes of a parent object and its child object when the width of the parent object is unknown (referred to as an auto-width), and the width of the parent's child object is expressed in percentages of the parent object width. A two-pass algorithm determines the best (or optimal) sizes of margins, borders, and paddings of objects where any combination thereof can have fixed width, auto width, and/or percentage-expressed width. Additionally, the algorithms can recursively calculate the optimal widths of objects inside other objects, where the outer object width is undefined. The algorithms can process an unlimited number of nesting levels.

Abstract: Methods and computer programs for automatically creating a text layout in an electronic design for a product to be printed. A number of defined text elements are available for user text entries. The product layout is based a user-selected image, if any, and on the text elements having user-supplied text content. Text elements without text content are disregarded. Positioning of user text entries is determined based on the size of the text entries, defined text element spacing distances, and defined positioning rules. Creating a layout incorporating user-supplied text entries and/or image may include cropping or resizing of other design elements in the product design and wrapping of relatively long text entries onto multiple lines.

Abstract: A method and device for displaying a document written in a Western language in a readable form without decreasing the utilization efficiency of a display screen. When a tail of a word to be displayed goes beyond an end of a line on the screen and the number of characters contained in the word does not exceeds a reference value, a line feed is inserted immediately before the word to perform word-wrapping, and when the number of characters contained in the word exceeds the reference value, a line feed is inserted halfway within the word to display divided parts of the word on different lines.

Abstract: The present invention is a system and method for showing as much horizontal data as possible without requiring horizontal scrolling while maintaining the attributes and benefits of a tabular display. This is achieved by dynamically splitting a row into two or more sub-rows when the row data would otherwise exceed the available horizontal space of the table control. This avoids the necessity to scroll, excessively compress the data or expand the table control. This is accomplished by the system having a tabular display unit for implementing the method comprising the steps of receiving a minimum size value of the tabular display; receiving a maximum size value of the tabular display; and dynamically splitting the horizontal data if the horizontal data exceeds the available horizontal space of the table control.

Abstract: The object of the invention is to easily and simply output a document including an image in a desired layout.

The script includes multiple drawing control commands that individually adjust output positions with regard to a plurality of images to be output in a preset output range. The sequence of arrangement of the multiple drawing control commands specifies the overlapping state of the plurality of images. The script of this construction enables the user to readily define and change the overlapping state and thereby attain a desired layout.

Abstract: A structure and method for automatically creating a dictionary for clustering text documents performs a first pass for each of the documents to determine a frequency of each word in each of the documents, creates a Hashtable of most frequently occurring words in the documents, performs a second pass for each of the documents to determine a frequency of phrases in each of the documents that contain only words in the Hashtable, adds the most frequently occurring phrases to the Hashtable, and outputting outputs the most frequently occurring words and the most frequently occurring phrases as the dictionary.

Abstract: Table elements, such as HTML elements, are automatically formatted relative to a change in visual appearance of a displayed decorative panel. The decorative panel comprises a plurality of separate but visually related regions defined by the table elements, and organized in predefined logical relationships to each other. A visual change causes an automatic revision to one or more attributes of the table elements that define the regions affected by the visual change. The visual change and automatic formatting are preferably accomplished with a Web page design tool, which identifies the decorative panel from comments associated with the table elements but do not affect rendering by a conventional browser. Visual properties of the decorative panel are mapped to the attributes, so that when the visual appearance is changed, a corresponding attribute is automatically revised. The resulting revised table elements are validated against predetermined inference rules that define valid patterns of regions.

Abstract: An apparatus, method, computer system, and computer program product to optimize space available for displaying text descriptions in a limited area, such as a sidebar. Space is optimized by displaying only the maximum portion of the text describing each selection that will fit within the limited area, thereby allowing space to display additional text descriptions in the remaining portion of the limited area. Positioning a pointer over the maximum portion of the text causes the complete portion of the text to be displayed. The complete portion of the text can serve as a link to content related to the text. Space is also optimized by providing a thin scroll bar to add space for displaying content within a window.
