VISUALIZING CONTENT REFERENCED IN AN ELECTRONIC DOCUMENT

Description

TECHNICAL FIELD

This disclosure relates generally to the technical fields of software and/or hardware technology and, in one example embodiment, to system and method for visualizing content referenced in an electronic document.

BACKGROUND

Many documents are generated in today's electronic society. An electronic document can include an object that provides an illustration or a visualization of a portion of the text in the document. For example, a United States patent document often has one or more drawings that appear close to the beginning of the document, while references to these drawing appear throughout the written description of the patent. For example, a document may have a figure titled “FIG. 1A” on page 2 of the document, which is referenced on page 12 of the document (e.g., page 12 of the document may include the text “FIG. 1A is a diagram illustrating . . . ”). When a user is reading the text on page 12 that references FIG. 1A, he might not remember all the details of FIG. 1A and may need to go back to page 2 to get the detailed information, and then return back to page 12. This may be very inconvenient and distracting from the flow of ideas. Existing viewing applications lack functionality that provides a convenient method to link a table or a figure in an electronic document to the text that is referring to such illustrative object.

DETAILED DESCRIPTION

In the following detailed description, numerous specific details are set forth to provide a thorough understanding of claimed subject matter. However, it will be understood by those skilled in the art that claimed subject matter may be practiced without these specific details. In other instances, methods, apparatuses or systems that would be known by one of ordinary skill have not been described in detail so as not to obscure claimed subject matter.

Some portions of the detailed description which follow are presented in terms of algorithms or symbolic representations of operations on binary digital signals stored within a memory of a specific apparatus or special purpose computing device or platform. In the context of this particular specification, the term specific apparatus or the like includes a general purpose computer once it is programmed to perform particular functions pursuant to instructions from program software. Algorithmic descriptions or symbolic representations are examples of techniques used by those of ordinary skill in the signal processing or related arts to convey the substance of their work to others skilled in the art. An algorithm is here, and generally, considered to be a self-consistent sequence of operations or similar signal processing leading to a desired result. In this context, operations or processing involve physical manipulation of physical quantities. Typically, although not necessarily, such quantities may take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared or otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to such signals as bits, data, values, elements, symbols, characters, terms, numbers, numerals or the like. It should be understood, however, that all of these or similar terms are to be associated with appropriate physical quantities and are merely convenient labels. Unless specifically stated otherwise, as apparent from the following discussion, it is appreciated that throughout this specification discussions utilizing terms such as “processing,” “computing,” “calculating,” “determining” or the like refer to actions or processes of a specific apparatus, such as a special purpose computer or a similar special purpose electronic computing device. In the context of this specification, therefore, a special purpose computer or a similar special purpose electronic computing device is capable of manipulating or transforming signals, typically represented as physical electronic or magnetic quantities within memories, registers, or other information storage devices, transmission devices, or display devices of the special purpose computer or similar special purpose electronic computing device.

As used herein, a “document” or “an electronic document” refers to electronic media content that is accessible by computer technology. For example, a document can be a file that is not an executable file or a system file and includes data for use by a computer program. An example of a document includes a single or multiple files that are accessible by and/or associated with electronic document processing applications such as word processing applications, document viewers, email applications, presentation applications, spreadsheet applications, diagramming applications, graphic editors, graphic viewers, enterprise applications, and other applications. Therefore, as explained in more detail below, a document may be composed of alphanumeric texts, symbols, images, videos, sounds, and other data. It should be appreciated that a document can have a variety of file formats that, for example, may be identified by data within a document and/or by the filename extension. Examples of file formats that may be associated with a document include Adobe Portable Document Format (PDF), Microsoft DOC format, Hypertext Markup Language (HTML) format, Extensible Markup Language (XML) format, Microsoft XLS format, Tag Image File Format (TIFF), Rich TextFormat (RTF), and Report File Format (RPT).

Method and system are described that facilitate visualizing content referenced in an electronic document. In one embodiment, the system is configured to allow a user to access an illustrative object (e.g., a table or a drawing) that is present in an electronic document from a location where the document text is referring to that illustrative object. Example method and system described herein utilize a float window feature with an illustrative object referenced in the text when a user positions the cursor over the text that references that object. In one embodiment, when the cursor is moved away from the referencing text, the float window is removed from the display screen. The method and system described herein may be utilized, beneficially with personal computer devices including desktop computers, laptop computers, and devices with smaller screen size, e.g., touch pads or smart phones.

FIG. 1 shows a diagram of a computer system 100 that may be used to provide method and system for visualizing content referenced in an electronic document may be implemented, in accordance with an example embodiment. The computer system 100 comprises one or more processors including a processor 110 coupled to a memory 120 and a viewing application 130. The viewing application 130 includes a float window nodule 132. The float window module may be implemented as a module that is part of the viewing application 130 or as a plug-in that can be utilized with the viewing application 132. The float window module 132, in one example embodiment, is configured to allow a user to access an illustrative object that is present in an electronic document from a location where the document text is referring to that illustrative object. FIG. 2 is a block diagram illustrating a system for visualizing content referenced in an electronic document, e.g., implemented as the floating window module 132.

FIG. 2 is a block diagram illustrating a system 200 for visualizing content referenced in an electronic document. In one example embodiment, the system 200 for visualizing content referenced in an electronic document may be associated with a viewing application and may correspond to the floating window module 132 of FIG. 1. Each of the modules of the system 200 may be implemented utilizing at least one processor.

As shown in FIG. 2, the system 200 includes an access module 202, a reference detector 204, and a float window loader 206. The access module 202 may be configured to open electronic documents. As mentioned above, an electronic document may include descriptive textual content, as well as illustrative objects, such as, e.g., tables and drawings (or figures). An illustrative object may be identified by a label, e.g., “Table 1” if the illustrative object is a table, or “FIG. 1,” if the illustrative object is a drawing. The reference detector 204 may be configured to detect that a cursor, controlled by a user, is positioned over text in the descriptive content that refers to the illustrative object (e.g., over a label “Table 1” or “FIG. 1”).

The reference detector 204 cooperates with the float window loader 206, which is configured to respond to detecting the cursor being positioned over text in the descriptive content referring to the illustrative object by loading the associated illustrative object into memory and rendering the illustrative object in a float window. The float window may be presented in a display area of the document viewing application, e.g., as shown in FIG. 5, which is described further below. The reference detector 204 may also cooperate with a cursor presentation module 208. The cursor presentation module 208, shown in FIG. 2, may be configured to present change the shape of the cursor the cursor being positioned over text in the descriptive content referring to the illustrative object. For example, the cursor presentation module 208 may present a cursor as a shape indicating availability of the float window functionality.

In one example embodiment, the reference detector 204 detects that a cursor is positioned over text referring to an illustrative object by recognizing that certain text is tagged with a reference label. The reference detector 204 may be configured to identify text tagged with a reference label as referring to the associated illustrative object. The tagging of text (an alpha-numeric string) may be performed by a document preparation module 210 shown in FIG. 2. In one embodiment, the document preparation module 210 may be configured to detect an illustrative object in an electronic document, determine an identification label associated with the illustrative object, scan the electronic document to detect one or more text items that refer to the illustrative object, and tag each of these text items with a reference label that corresponds to the identification label. As mentioned above, a document may be provided in a variety of formats, including Adobe® Portable Document Format (PDF).

The system 200, as shown in FIG. 2, comprises a plurality of components (or modules), some of which may be implemented as part of a viewing application (e.g., the viewing application 130 of FIG. 1), while others may be implemented as either part of the viewing application or as part of a plug-in that cooperates with and functions in conjunction with the viewing application. For example, the access module 202 may be provided as part of a document viewing application, while the reference detector 204, the float window loader 206, the cursor presentation module 208, and the document preparation module 210 may provided as part of a plug-in associated with the document viewing application. Example operations performed by the system 200 for visualizing content referenced in an electronic document are described with reference to FIG. 3.

FIG. 3 is a flow chart illustrating a method 300 for visualizing content referenced in an electronic document, in accordance with an example embodiment. The method 300 may be performed by processing logic that may comprise hardware (e.g., dedicated logic, programmable logic, microcode, etc.), software (such as run on a general purpose computer system or a dedicated machine), or a combination of both. In one example embodiment, the processing logic resides at the computer system 100 of FIG. 1 and, specifically, at the system 200 shown in FIG. 2.

As shown in FIG. 3, the method 300 commences at operation 310 when the access module 202 of FIG. 2 opens electronic documents. In one embodiment, the electronic document includes descriptive textual content, as well as illustrative objects, such as, e.g., tables and drawings (or figures). At operation 320, the reference detector 204 of FIG. 2 detects that a cursor is positioned over text in the descriptive content that refers to the illustrative object (e.g., over a label “Table 1” or “FIG. 1”). While an illustrative object may be self contained in that it has all context needed for its rendering, in some embodiments the context associated with the main window (e.g., settings such as color, font, etc.) is collected before the illustrative object is rendered in a float window.

At operation 330, the float window loader 206 of FIG. 2 responds to the reference detector 204 detecting the cursor being positioned over text in the descriptive content referring to the illustrative object by loading the associated illustrative object into memory. At operation 340, the float window loader 206 renders the illustrative object in a float window. The float window may be presented in a display area of the document viewing application, e.g., as shown in FIG. 4.

FIG. 4 is an example user interface 400 illustrating visualizing content referenced in an electronic document, in accordance with an example embodiment. Shown in FIG. 4 is a display area of a document viewing application 410. Displayed in the display area 410 is a portion of an electronic document that includes textual references to drawings, in the form of alpha-numeric strings that read “FIG. 1A,” “FIG. 1B,” “FIG. 1C,” etc. The text that reads strings that read “FIG. 1A” is identified with reference numeral 412. Shown in FIG. 4 is a cursor 414 positioned over the text 412. The shape of the cursor indicates that float window functionality is available with respect to the text 412. In one example embodiment, the float window functionality may be invoked by clicking on the text 412. In response, a float window 420 is presented, displaying the drawing (FIG. 1A) referenced by the text 412.

FIG. 5 is a flow chart illustrating a method 500 for preparing an electronic document, in accordance with an example embodiment. The method 500 may be performed by processing logic that may comprise hardware (e.g., dedicated logic, programmable logic, microcode, etc.), software (such as run on a general purpose computer system or a dedicated machine), or a combination of both. In one example embodiment, the processing logic resides at the computer system 100 of FIG. 1 and, specifically, at the system 200 shown in FIG. 2.

As shown in FIG. 5, the method 500 commences at operation 510 when the document preparation module 210 of FIG. 2 detects an illustrative object in an electronic document. As mentioned above, the electronic document may include descriptive textual content, as well as illustrative objects, such as, e.g., tables and drawings (or figures). An illustrative object has an identification label. For example, an identification label for a drawing may be “FIG. 1.” An identification label for a table may be “Table 1.”

At operation 520, the document preparation module 210 determines an identification label associated with the illustrative object. At operation 530, the document preparation module 210 scans the electronic document to detect whether there are any text items that refer to the illustrative object. At operation 540, the document preparation module 210 tags each of these detected text items with a reference label that corresponds to the identification label. the document preparation module 210 As described above, a tag may be used by the reference detector 204 of FIG. 2 to detect that certain text in the descriptive content in an electronic document refers to a particular illustrative object and that a cursor is positioned over text in the descriptive content that refers to the illustrative object.

The document preparation module 210 also adds a link to the associated illustrative object such that the text that refers to the illustrative object can function as a control that can be activated and cause the launching of a float window displaying the illustrative object.

In one example embodiment, a viewing application, also termed an electronic document reader, may be provided with a default configuration that comprises regular expressions for use in matching tagged text in an electronic document. For example, assuming that the tagged text in electronic documents includes strings such as “Figure,” “Fig,” “Table,” and “Chart,” a viewing application default configuration may include regular expressions shown in Table 1 below.

TABLE 1

‘Figure(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

‘Fig(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

‘Table(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

‘Chart(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

For example, in order to locate and tag a table labeled “Table 2.1 Different Formats Used by Microsoft in the Past 10 Years,” a script shown in Table 2 below may be utilized.

TABLE 2

import re

m = re.search (‘Table(.{0,5})([0-

9]+)(.{0,1})([0-9]*)’, ‘Table 2.1

Different Formats Used by Microsoft in

the Past 10 Years’, re.IGNORECASE)

if m is None :

print “\nnone matched!”

else:

print (“\n%s” % m.group(0))

A viewing application may then execute commands linking the tagged text “Table 2.1” to the corresponding table object in the electronic document.

A viewing application may also be provided with a configuration GUI to let a user add their own custom regular expressions to the default configuration, such as, e.g., a regular expression for tagging a string that starts with the word “Formula.” An example of a formula and an associated text is shown in Table 3 below.

TABLE 3

The finial formula 3.2.5 is,

\begin{matrix} L = \log_{2} (\max (\sqrt{{(\frac{\partial u_{texel}}{\partial x_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial x_{s}})}^{2}}, \sqrt{{(\frac{\partial u_{texel}}{\partial y_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial y_{s}})}^{2}})) \\ = \log_{2} (\sqrt{\max ({(\frac{\partial u_{texel}}{\partial x_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial x_{s}})}^{2}, {(\frac{\partial u_{texel}}{\partial y_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial y_{s}})}^{2})}) \\ = \frac{1}{2} \log_{2} (\max ({(\frac{\partial u_{texel}}{\partial x_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial x_{s}})}^{2}, {(\frac{\partial u_{texel}}{\partial y_{s}})}^{2} + {(\frac{\partial v_{texel}}{\partial y_{s}})}^{2})) \end{matrix}

In this scenario, auser can use configuration GUI to add his own regular expression ‘Formula(.{0,5})([0-9]+)(.{0,1})([0-9]*)’ to get all formula photos and tagged text tracked.

EXAMPLE IMPLEMENTATION

Example system and method for visualizing content referenced in an electronic document may be implemented as described below.

A viewing application configuration may include two lists: one list being a list of regular expressions for various formats of tagged text of illustrative objects (e.g., tables, charts, formulas, figures, etc.), the other list being a so-called priority list that includes respective expected positions of the tagged text in an electronic document. An example of these two lists is shown in Table 4 below.

TABLE 4

Tagged Text:

‘Figure(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

‘Fig(.{0,5})([0-9]+)({0,1})([0-9]*)’

‘Table(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

‘Chart(.{0,5})([0-9]+)(.{0,1})([0-9]*)’

Position Priority:

Priority 1: ‘The first line of text just below the illustrative

object’

Priority 2: ‘The first line of text just above the illustrative

object’

In one embodiment, a viewing application records and stores tagged text, an associated illustrative object, and the context associated with the illustrative object in a designated container. Such container (called “Manager” in the example shown in Table 4 below) may include a list of structures (structures called “ManagedItem” in the example shown in Table 5 below), where each “ManagedItem” structure has elements such as tagged text, illustrative object id, and illustrative object context.

TABLE 5

ManagedItem {

Illustrative Object ID,

Illustrative Object Context ,

Tagged Text}

Manager = List < ManagedItems>

An example algorithm for finding a tagged text in an electronic document is shown below in Table 6.

TABLE 6

Read configuration list of tagged text regular expression

Read configuration list of text position priority

Initialize “Manager”,

Scan Document,

Loop1: get next illustrative object (table / figure)

Created a new “ManagedItem”,

Set illustrative object ID of that “ManagedItem”

Collect “Context” of that illustrative object, set it to “Context” of that

“ManagedItem”

Loop2: iterator priority position rule to get corresponding text around

that illustrative object.

Loop3: iterator matching conditions to get matched tagged text

If get matched tagged text ,

Set matched tagged text to “tagged text” of that

ManagedItem

Exit loop3: matching conditions

Exit loop2: priority positions

End Loop3

End Loop2

If ManagedItem's tagged text has a valid value

Put ManagedItem in to Manager.

Else (note: after Loop2 × Loop3, there is no matched tagged text

found)

Illustrative has no match tagged text, skip it.

End Loop1

An example algorithm for redrawing referenced tagged text is shown below in Table 7.

TABLE 7

Loop1: Iterate “ManagedItem” in “Manager”,

Get tagged text

Scan all text in the document and search tagged text

While: find one

Redraw it as hotlinked Tagged Text

Link it to related ManagedItem

End While

End Loop1

An example algorithm for displaying illustrative objects is shown below in Table 8.

TABLE 8

When the cursor moves over the tagged and linked text

If its FloatWindow showing

Skip

Else

Get its ManagedItem,

Get illustrative object ID

Get its illustrative object display context

Create a float window

Load illustrative object

Draw illustrative object with its display

context.

When the cursor moves out of the tagged and linked text

If FloatWindow showing

Destroy the illustrative object

Destroy the float window

Else

Skip
