Abstract
A method for extracting Anchorable Information Units (AIUs), from a Portable Document Format (PDF) file, which may either be created using either an editor or by scanning in documents. The method includes parsing the portable document format document into textual portions and non-text portions, and extracting structure from the textual portions and the non-text portions. The method further includes determining text within textual portions, and text the non-text portions, and hyperlinking a plurality of keywords within the textual portions and non-text portions to a related document.
Claims28
A system for processing a multimedia data file to provide information supporting user navigation of multimedia data file content, comprising:
- a content parser to identify text and image content of a data file;
- an image processor for processing said identified image content to identify embedded text content;
- a text sorter for parsing said identified text and said identified embedded text to locate text items in accordance with predetermined sorting rules;
- and
- memory for storing a navigation file containing said text items.
A graphical User interface system supporting processing of a multimedia data file to provide information supporting user navigation of multimedia data file content, comprising:
- a menu generator for generating,
- one or more menus permitting User selection of, an input file and format to be processed;
- and
- an icon permitting User initiation of generation of a navigation file supporting linking of input file elements to external documents by parsing and sorting text and image content to identify text for incorporation in a navigation file.
A method of creating an anchorable information unit in a portable document format document, comprising the steps of:
- extracting a text segment from the portable document format document;
- determining a context of the segment, wherein the context is selected from a context sensitive hierarchical structure;
- and
- defining the text segment as an anchorable information unit according to the context.
A program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform method steps for creating an anchorable information unit file from a portable document format document, the method steps comprising:
- parsing the portable document format document into textual portions and non-text portions;
- extracting structure from the textual portions and the non-text portions;
- determining text within textual portions, and text the non-text portions;
- and
- hyperlinking a plurality of keywords within the textual portions and non-text portions to a related document.
