CROSS REFERENCE TO CO-PENDING APPLICATION  
       [0001]     This application is a continuation-in-part of co-pending U.S. application Ser. No. 11/032,383, filed Jan. 10, 2005, the contents of which are incorporated herein in its entirety, which claims the benefit of the priority filing date of U.S. Provisional Patent Application Ser. No. 60/535,383 filed Jan. 9, 2004, the contents of which are incorporated herein in its entirety. 
     
    
     BACKGROUND  
       [0002]     The present invention relates in general to the production of student compositions. Available word processing software products for personal computers have added new features over the years. Although these new features appear to increase product functionality, they have the negative effect of making the software more and more difficult to use, thereby limiting its actual use.  
         [0003]     Available products rely more and more on artificial intelligence (AI), but manual intervention is still required because AI capabilities are not foolproof. Compared to the real intelligence afforded by structured SGML and XML documents, AI comes up short. Structured documents are content-based whereas documents produced with available word processing software are based on the presentation format.  
         [0004]     Content-based structured documents provide a variety of benefits over format-based documents including the ability to publish the same text in multiple presentation styles to all types of media and to reuse and interchange information without regard for presentation style.  
         [0005]     A major problem for production of structured documents is document creation. Available tools for producing structured documents require significant training and specialized knowledge, both of which are inappropriate for the student age group. At the same time, conversion of documents authored in conventional word processors is a time-consuming and error-prone process that is also not appropriate for the student age group.  
         [0006]     The present apparatus and method utilizes menu-free, point-and-click, user-chosen graphical user interfaces that can be personalized by users to make the advantages of structured documents easily accessible to students for their school compositions without special training or expert knowledge.  
         [0007]     Some of the documents students write include any of the following:  
         [0008]     Poetry: Haiku, Limerick, Sonnet;  
         [0009]     Fiction: Short Story, School Play;  
         [0010]     Reports: Book Report, Lab Report, General Report;  
         [0011]     Non-Fiction: Essay;  
         [0012]     Research: Term Paper, Research Paper, Thesis, Dissertation.  
         [0013]     Student compositions such as these have specific requirements for structure and formatting. The “rules” are fairly simple for poems, but other documents, such as lab reports, have a lot more rules. Students encountering these documents for the first time are not familiar with the rules and naturally can use all the help they can get to adhere to the structure and formatting requirements.  
         [0014]     Even older students experienced in writing student compositions can use help with research papers. Research papers have the most complex structural and formatting requirements which include font size, margins and indents as well as complex rules for bibliographic and citation information. The requirements vary according to the citation style used, which depends on the field of study and the requirements of the school and instructor.  
         [0015]     There are many citation styles in use today. The “Big Three” citation style organizations publish their rules as follows:  
         [0016]     American Psychological Association (APA) publishes a Publication Manual for use in the fields of psychology, sociology, business, economics, nursing, social work, and justice administration. To readily identify recent research, text citations show the author&#39;s surname and the year of publication.  
         [0017]     Chicago/Turabian style publishes Manual for Writers of Term Papers, Theses, and Dissertations for use in the humanities, social sciences and natural sciences. In addition to text citations in the text, it allows footnotes and end notes, depending on the field of study.  
         [0018]     Modern Languages Association (MLA) publishes a MLA Handbook for Writers of Research Papers for high school and undergraduate college students and a MLA Style Manual and Guide to Scholarly Publishing for graduate students, scholars, and professional writers. MLA style is used in humanities research. For text citations, to make quotations easy to find, text citations use the author&#39;s surname and the page number(s) in the cited work.  
         [0019]     Some students need just one citation style during their academic careers, but others are not so lucky. A psychology professor may specify APA, a paper for a literature course may need MLA style, and the school may require Chicago/Turabian for theses and dissertations.  
         [0020]     It is important to bear in mind that accurate citations make the difference between research and plagiarism, and many instructors deduct grade points for citation errors. Others have a less stringent policy, but student grades may still be adversely affected by citation errors. The comments of one English professor reveal the student&#39;s dilemma:  
         [0021]     “There are professors out there who insist on letter-perfect papers before they&#39;ll even read them . . . I tell my students that I correct citation mechanics on papers, but don&#39;t factor such things into the grade. And I try to follow that, though I confess I don&#39;t always succeed. A paper that&#39;s sloppy in the citations will inevitably lower my opinion of the writer, and even if I try consciously to treat him or her fairly, the damage has been done. Conversely, a paper that&#39;s prepared to professional standards inevitably impresses me, and I might end up being more generous to it than to an equally good paper.” 
         [0022]     Most students cannot afford to pay an expert to ensure their papers are prepared to professional standards. The present invention incorporates the expert knowledge into the software. Formatting requirements and rules for bibliographies and citations are built into the software so students can get the same professional results without the expense of hiring a professional to review their papers.  
         [0023]     WO98/34179, U.S. Pat. No. 5,557,720 and U.S. Pat. No. 5,140,521 describe techniques for processing structured documents. In general, these patents relate to either altering a structured document or processing such documents to generate styled output for either display or printing.  
         [0024]     Thus, it would be desirable to provide a process for students to use a variety of menu-free, point-and-click graphical user interfaces to easily, accurately, and efficiently produce student compositions as structured documents that may include tables, graphics, and equations.  
         [0025]     It would also be desirable to provide students with the benefits of structured documents including:  
         [0026]     consistent formatting appropriate for the type of student composition;  
         [0027]     automatic system-generation of document contents such as text, numbering, graphics, symbols, spacing, punctuation, table of contents, list of tables, list of illustrations, citations, bibliography, list of references, list of works cited, and index as appropriate to the type of student composition;  
         [0028]     the ability to change presentation style and associated system-generated material at any time; and  
         [0029]     the ability to reuse portions of existing student compositions in new compositions without regard for presentation style or system-generated material.  
         [0030]     It would also be desirable to help improve student grades by providing automated tools to validate structured document content against applicable rules for the type of student composition as well as links to approved Internet sites related to the types of student compositions.  
         [0031]     Finally, it would be desirable to provide a better homework experience for students by delivering: consistently and correctly formatted documents in less time than needed with currently available tools; a user-friendly computer-game-like interface with sound effects and animation accompanying dialogs and messages; useful tools; and educational information about student compositions.  
       SUMMARY  
       [0032]     According to the invention, there is provided a document production process carried out by a system consisting of:  
         [0033]     customized structured document software;  
         [0034]     a set of predefined SGML and/or XML Document Types designed for student compositions each of which includes a Document Type Definition (DTD) that defines a document structure with required and optional SGML/XML elements and attributes suitable to the type of student composition; a variety of stylesheets supporting presentation styles suitable to the type of student composition; and other electronic files and scripts as needed to customize the Document Type for the type of student composition;  
         [0035]     a variety of menu-free, point-and-click graphical user interfaces that include an authoring/editing window, a print preview display window; elements that can be used in each particular type of student composition; educational information about each type of student composition; automated tools to validate the composition content against the rules for the student composition; and Internet links appropriate to the type of student composition; and  
         [0036]     optional computer-game-like sound effects and animation accompanying system dialogs and messages.

     DETAILED DESCRIPTION  
       [0055]     As shown periodically in  FIG. 1 , the present invention is a software program which can be loaded from a computer storage media, i.e., a CD, into a memory for execution by a processor, or downloaded from a telecommunication network and allows users to choose from a variety of graphical user interfaces  20  from a variety of themes including, but not limited to, cockpits (boat, plane, race car, motorcycle, space ship); desktops (student, office, doctor, lawyer, scientist, president); music (stereo controls, electronic music console, electronic keyboards); nature (beach bag, mountain climbing kit, fishing tackle box); playing field (baseball, basketball, football, hockey, soccer, tennis); vanity table (manicure set, makeup kit, jewelry box); each of which provides access to electronic files with existing structured documents  22  and the ability to create electronic files with new structured documents based on the type of school composition to be produced. The graphical user interface  20  also provides point-and-click access to a Tool Palette  30 , Message Console  32 , Tag Palette  34 , and Global properties  37  and Local Properties  36  as shown in  FIGS. 2-6 .  
         [0056]     Each type of school composition is an SGML or XML Document Type named for the type of composition and consisting of a Document Type Definition (DTD) file, stylesheets files, and other electronic files and scripts necessary to create and customize the Document Type. The Document Types include but are not limited to: Haiku,  FIG. 9 , Book Report,  FIG. 3 , Research Paper,  FIG. 4 , Term Paper, Essay, Lab Report, Short Story, School Play, Sonnet, Limerick.  
         [0057]     A structured document is created, added to, and changed according to the framework defined in the Document Type DTD.  
         [0058]     The new or existing document is displayed in the Edit Window  40 ,  FIG. 3 , portion of the user-selected graphical user interface. In the displayed structured document, iconic pictures (“tags”) represent SGML/SML elements. The first tag in the document represents the Document Type.  
         [0059]     Within the Edit Window, the program supports the authoring and editing tasks of typing, backspacing, deleting, moving, copying, pasting, spell checking, etc. The graphical user interface  20  provides point-and-click access to file-related and editing-related operations.  
         [0060]     The graphical user interface  20  also displays a palette of the tags  34  that can be inserted into the structured document. The allowable tags  34  depend on the type of school composition to be produced. For example, the tags  34  for a haiku poem are not the same as the tags  34  for a Book Report, and the Equation tag  34  that is allowed in a Research Paper is not available in a Sonnet.  
         [0061]     Within a structured document, the allowable tags  34  may change depending on the location of the cursor in the document. For example, if the cursor is located in the body of a Book Report Document, available tags  34  include paragraphs and lists, neither of which is available when the cursor is located in the title of the Book Report.  
         [0062]     This context-sensitivity ensures that the structured document is always properly structured according to the Document Type Definition for that type of school composition. Similarly, although tags as well as text can be cut and copied, tags  34  that are required for the document structure are not allowed to be deleted and tags  34  are not allowed to be pasted in a location that would violate the document structure. Whenever possible, the program transforms the disallowed tag into an allowed tag.  
         [0063]     To insert an available tag, the user clicks on it in the Tag Palette  34  and begins typing. Alternatively, the user can begin typing anywhere a paragraph is allowed and a paragraph tag  34  will be automatically inserted around the typed text.  
         [0064]     The graphical user interface  20  hides tags  34  except for tags that can be moved or deleted. For tags  34  that can be moved or deleted, the single tag or the end tag of any double tag is displayed in conjunction with a symbol, which serves as a handle  50 , as show in  FIG. 6 . A tag  34  that is not allowed to be moved does not have a handle  50 . For example, the title tag in a chapter cannot be moved because it belongs in one place, which is at the beginning of the chapter. A paragraph tag, however, can be moved to a variety of places, so the end tag of the paragraph tag contains a handle  50 . The graphical user interface  20  allows the user to choose the appearance of the handle  50  from a variety of symbols including, but not limited to, an airplane, a floral symbol, and a triangle.  
         [0065]     Within a structured document, tags  34  contain color-coded tag borders  52  as property indicators, as shown in  FIG. 6 . For example, tags  34  that have a red border have properties that a user may change, and tags  34  with a black border have no changeable properties. Further, the color-coded tag border can also act as an indicator of formatting that has been specified by the student. For example, a lime border can indicate that a user has specified single spacing and standard paging.  
         [0066]     Textual tags interfere with the reading and writing processes. The graphical user interface  20  displays graphics in association with all start, end, and single tags in order to communicate tag information to users without the need for them to read textual tags. The interface approach is designed to utilize both halves of the human brain. The right half of the brain, which receives information from the left eye, processes colors and graphics. The left half of the brain, which receives input from the right eye, processes black and white. The left half of the brain handles reading but does not see graphics. As shown in  FIG. 6 , the graphical user interface  20  is set up to place tags  34  on the left side of Edit Window  40  where it is easy for the left eye to see. Thus, it will be easier for a user to process tag information through the right brain while reading and writing is accomplished through the left brain. The result is that tags are displayed, but they are invisible to the left brain, so they do not impede the user&#39;s authoring and editing.  
         [0067]     At any time, the structured document displayed in the Edit Window  40  can be previewed so its print image is displayed in the side-by-side Preview Window  42  that is also part of the graphical user interface. The user can click on text in the Preview Window  42  and be linked to the location of that text in the Edit Window  40 .  
         [0068]     Formatting is linked to the tags  34  in the structured document but is stored separately from the document text, which enables the document to be instantly formatted into a variety of presentation styles. Default presentation styles can be used to produce a correctly formatted school composition in minimum time.  
         [0069]     Formatting can be changed at any time by choosing a different predefined presentation style and/or modifying the Properties (SGML/XML attributes) associated with each tag  34  by simply double-clicking on the tag in the Edit Window  40  to display a dialog for viewing and changing Properties. There is no need to select text or tags in the Edit Window  40  to change formatting properties.  
         [0070]     The tag  34  representing the Document Type has properties that affect the entire document (Global Properties  37 ) while the properties for other tags affect only the text inside those tags (Local Properties  36 ).  
         [0071]     Global Properties  37  include the language of the document, paper size, font color, background color, background image. Global Properties  37  also include a variety of predefined styles each with its own font(s), color scheme, and layout designed to facilitate and enhance readers&#39; perception of the document contents. The Global Properties  37  associated with a Document Type tag depend on what is suitable for that Document Type. Citation Style is a Global Property in the Research Paper Document Type that is not available in the Haiku Document Type.  
         [0072]     One or more frequently used Global Properties  37 , such as Document Font, is displayed directly in the graphical user interface, see  FIGS. 3, 6 ,  8 , and  9 , in a way that users can manipulate with a mouse to select the desired setting.  
         [0073]     Some Global Properties  37  are available as Local Properties  36  on non-Document Type tags to override the properties set on the Document Tag. For example, the Global Properties  37  may specify the bullet list style for the entire document, but if a different style is desired for a particular bullet list, its Local Properties  36  can be set to override the Global Properties  37 . Global  37  and Local Properties  36  can be used together as desired to craft custom presentation styles for the document.  
         [0074]     To access Global Properties, the user double clicks on the icon  37  in  FIG. 3  after a tag, or clicks once after the tag  34  then clicks on the icon tag properties  39 . Similarly, to access Local Properties, the user double clicks on the icon  36  in  FIG. 3  after a tag, or clicks once after the tag  34  then clicks on the tag properties icon  39 .  
         [0075]     Structured documents produced with the program can be previewed  44 ,  FIG. 1 , printed  46  to paper or electronic file, and saved as HTML  48  with formatting based on the printed image.  
         [0076]     The contents of the Edit Window  40  can be printed with or without tags.  
         [0077]     Tools are provided for each Document Type whose purpose is to validate structured student documents against the rules for the type of composition. For example, the Haiku Document Type has a Check Haiku tool  54  to check the syllable count for each line of the Haiku poem and report lines with the incorrect number of syllables.  
         [0078]      FIGS. 7-9  depict a different graphical user interface  20  suited, by example, for a female. The same Tool Palette  30 , Message Console  32 , Tag Palette  34  are employed and presented for selection by the user.  
         [0079]     The following example of a Research Paper Document,  FIG. 4 , illustrates how the program works.  
         [0080]     The Research Paper Document Type will automatically format the paper according to the citation style chosen by the student. The student just needs to type inside the appropriate tags. The software will do the rest as described below.  
         [0081]     In the graphic shown in  FIG. 15 , which shows the beginning of a Research paper Document, the Paragraph, Figure and Equation tags are “double tags” with a “start tag” and a smaller matching “end tag.” Double tags and single tags use different color schemes so it is easy to tell them apart. The user types in between double tags.  
         [0082]     The Cross Reference, Bibliography Magician and Graphic tags are “single tags.” Only one tag is needed because it opens a dialog. A sample dialog is shown in  FIG. 16  for the Cross Reference tag.  
         [0083]     When students want to include a citation in the text of their papers, they will insert the Bibliography Magician tag, the Research Paper Document&#39;s most powerful tag.  FIG. 17  shows how students will enter only the raw information about the source they are citing into a dialog box.  
         [0084]     The program will do the rest, providing the spacing, punctuation, abbreviations, underlining and anything else required for the chosen citation style. For example, the following graphic shows how the citation information entered in the Bibliography Magician dialog above will be formatted when MLA style is selected:  
         [0085]     cupy uf cak vux noaw yerw phuno (Rockefeller 34).  
         [0086]     When APA style is chosen, the citation will be formatted as shown in the graphic below:  
         [0087]     cupy uf cak vux noaw yerw phuno (Rockefeller 1955).  
         [0088]     In addition to inserting the citation in the text, the invention generates the list of works cited in the paper. For example, the citation below shows the Rockefeller entry when MLA style is selected:  
         [0089]     Rockefeller, John D. IV. (1955)  Autobiography.  New York: Random.  
         [0090]     The following citation shows the same entry in APA style:  
         [0091]     Rockefeller, J. D., IV (1955)  Autobiography.  New York: Random.  
         [0092]     The program will also provide the correct title for the list of works cited. When the chosen citation style is MLA or Chicago/Turabian, “Works Cited” will be inserted; when APA style is selected, “References” will be generated.  
         [0093]     In addition, when Chicago/Turabian style is chosen, the program will generate a title page, table of contents, list of figures and list of tables. Also, an abstract will be required and a dedication will be allowed. If the student changes the citation style from Chicago/Turabian style to MLA or APA, the title page, table of contents, list of figures, list of tables, abstract and dedication will not appear in the preview or printout.  
         [0094]     To generate the bibliography in the College/University Edition, the user selects a citation style from a dialog box and then previews or prints the document. If the user does not specify a style, the default style (MLA) is used. At any time the user can select another citation style and preview or print the document to generate the bibliography in the new citation style. The bibliography is not part of the document. It is generated when the document is previewed or printed and exists only in the output. The input contains only the citation information embedded in the text.  
         [0095]     Students naturally want to re-purpose their research papers when possible. The program will make it easy. Students will be able to:  
         [0096]     copy citations from existing Research Paper Documents and paste them in new Research Paper Documents without concern for the citation style. The invention will format the new paper according to the selected citation style; and/or  
         [0097]     change from one citation style to a second to a third, and back again, with a click of the mouse. The invention will automatically re-format the citations and the list of references/works cited using whatever spacing, punctuation and formatting are appropriate for the selected citation style.  
         [0098]     All Research Paper Document formatting is completely automatic. The program will:  
         [0099]     format text according to its tag  34 , including automatic numbering of lists, outlines, footnotes, table, equations and figures;  
         [0100]     insert cross reference text;  
         [0101]     format footnotes and end notes;  
         [0102]     include the appropriate page headers, footers and numbering;  
         [0103]     insert citation information in the text in accordance with the chosen citation style;  
         [0104]     generate the list of references/works cited with the title required by the citation style;  
         [0105]     generate a title page, table of contents, list of tables, and list of figures when appropriate for the citation style; and/or  
         [0106]     generate an index if desired.  
         [0107]     The Research Paper Document will include features such as:  
         [0108]     a WYSIWYG Table Designer that enables students to easily create, edit and format tables as well as copy tables from Microsoft Excel;  
         [0109]     a WYSIWYG Equation Creator that enables students to easily create, edit and format complex equations;  
         [0110]     a Document Map feature to enable users to easily navigate long documents; and/or  
         [0111]     excerpts from supported citation style guides as electronic files that students can search to quickly locate the information they need.  
         [0112]     The program is an application of PTC/Arbortext&#39;s Arbortext Editor™ software that is implemented by accomplishing tasks including, but not limited to, the following:  
         [0113]     providing the following application programs for each type of student composition to be supported in the product. Together these electronic files comprise an SGML or XML Document Type.  
         [0114]     Document Type Definition (DTD) which defines the structure of the Document Type; for example haiku.dtd.  
         [0115]     Format Output Specification Instance (FOSI) which specifies the formatting for documents authored according to the structure defined in the DTD including the screen display formatting in the Edit Window; for example, haiku.fos.  
         [0116]     Document Type Configuration File (DCF) which customizes the Document Type within Arbortext Editor; for example haiku.dcf.  
         [0117]     An SGML/XML sample document for each Document Type; for example, haiku.xml.  
         [0118]     An SGML/XML Catalog electronic file that includes the SGML/XML Public Identifier for each Document Type and its location in the electronic file system to enable Arbortext Editor to find the relevant files for each Document Type.  
         [0119]     Programs and scripts in Arbortext Command Language (ACL), XML-based User Interface (XUI), Java, and/or other application programming languages to:  
         [0120]     display the graphical user interfaces;  
         [0121]     activate the buttons, controls, and tools in the graphical user interfaces;  
         [0122]     provide functionality for tools and features;  
         [0123]     provide software programs, scripts, databases, and other electronic files and use ACL, Java, and/or other application programming languages to integrate them into Arbortext Editor as described in Arbortext Editor documentation to support product features such as hyphenation, syllable counting, rhyme checking, and verbal proofreading:  
         [0124]     specialty dictionaries (medical, legal, etc.);  
         [0125]     Syllabic dictionaries;  
         [0126]     rhyme databases;  
         [0127]     text-to-speech technology;  
         [0128]     provide access from within the product to online databases such as ISBN/ISSN information and develop ACL, Java, or other programs and/or scripts to automatically populate elements and attributes in a Research paper Document with information from the database;  
         [0129]     provide product help information including, but not limited to, the following tasks and deploy in the program as HTML online help according to Arbortext Editor documentation;  
         [0130]     information about how to use, and when applicable how to personalize all product features;  
         [0131]     interactive tutorials on how to use, and when applicable how to personalize all product features;  
         [0132]     educational information about student documents to be written by subject matter experts;  
         [0133]     a list of Internet links to sites related to student documents to be compiled by subject matter experts; and  
         [0134]     reproduction of excerpts from citation style guides and other reference materials as part of product online help information;  
         [0135]     Given the ingenuity of some young people, unused Arbortext Editor functionality could be disabled so it is not possible for users to access more than they purchased.  
         [0136]      FIG. 10  is a flowchart showing how a student clicks on the Paragraph tag in the Tag Palette ( 34 ), step  60 . Custom scripting translates the click into the Arbortext Editor ACL command “it para”, step  62 , which inserts a Paragraph tag at the next place it is allowed in the structured document as dictated by the Document Type Definition (DTD), step  64 . The FOSI stylesheet then causes the tag to be displayed as a graphic icon for the first tag in the tag pair (Start Tag) ( 34   a ) and a smaller matching graphic icon for the second tag in the tag pair (End Tag) ( 34   b ), step  66 . For tags or elements that are allowed by the DTD to be moved to different locations in the document, settings in the DCF configuration file cause an additional icon to be displayed with the Paragraph Start Tag and/or End Tag icon, step  68 .  
         [0137]      FIG. 11  is a flowchart showing in steps  70 ,  72  and  74 , how the Check Haiku tool ( 54 ) available with the Haiku Document Type is activated by the student to count the syllables in each line of the haiku poem, check them against the number of syllables that should be included in each of the three lines of a haiku poem, and report the results to the student in the Message Window ( 32 ).  
         [0138]      FIG. 12  shows part of the XML DTD that defines the Haiku Document Type&#39;s structure and the elements (“tags”) allowed, specifically: the singleton tags Graphic, Bold, Italic, Underline, Newline, and Tab, and the tag pairs Haiku, Title, Your-Name, Line 1 , Line 2 , and Line 3 .  
         [0139]      FIG. 13  shows an XML document instance that uses the following tags: Haiku, Graphic, Title, Your-Name, Line 1 , Line 2 , and Line 3 . It includes only text and tags. Specifically, no formatting information is included.  
         [0140]      FIG. 14  shows one of the ways the document instance in  FIG. 13  can be formatted for print. The formatting for each tag is stored in a separate file and applied to the document shown in  FIG. 13  when it is previewed or printed. The formatting is never stored with the text and tags as shown in  FIG. 13  which means any number of stylesheets can be applied to the structured document to produce different formatted output.  
         [0141]     Many additional features can be provided as described below.  
         [0142]     Additional Graphical User Interfaces:  
         [0143]     additional graphical user interfaces can be added, including new themes and color combinations.  
         [0144]     Additional Citation Styles:  
         [0145]     Both MLA and Turabian/Chicago styles include alternate formats that can be added to the Research Paper Document:  
         [0146]     MLA Style includes Works Cited at the end of a paper to provide reference information. An earlier style, now going out of date, is to use footnotes. This style can be supported in the Research Paper if absolutely necessary. Footnote formatting in Arbortext Editor has limitations; and  
         [0147]     Turabian/Chicago style has an alternate citation style that numbers each citation and lists the numbered references at the end of the paper. The citation in text is a number in square brackets. This citation style can be supported in the Research Paper.  
         [0148]     Support can also be added for other popular citation styles required by colleges/universities and academic associations and journals. For example:  
         [0149]     Harvard Style, required at Harvard and other colleges and universities;  
         [0150]     Yale Style, required at Yale and other colleges and universities;  
         [0151]     CBE (Council of Biology Editors) Style, used by writers in the applied sciences and the medical sciences; and  
         [0152]     MHRA (Modern Humanities Research Association) Style, required by some humanities journals.  
         [0153]     Two additional variations of the author-date style in brackets (2]) are popular and can be supported. These styles are used in some computer-related journals.  
         [0154]     Some of the many other citation styles used by various disciplines are listed below:  
         [0155]     Chemistry—The ACS Style Guide: A Manual for Authors and Editors;

         [0167]     Sciences—American National Standard for the Preparation of Scientific Papers for Written or Oral Presentation.  
         [0168]     Additional Bibliography Magician Features:  
         [0169]     In the College/University Edition, additional bibliography features can be provided in the Research Paper Document. For example:  
         [0170]     A “no-tags” view of the document could be selected for easy onscreen reading, using icons to represent citations in text. Double-clicking on an icon would display the citation.  
         [0171]     A “draft” of the list of references/works cited could be generated without printing the entire document.  
         [0172]     The list of references/works cited could be displayed in a separate window side by side with the Editor Window so the user could double-click on each item in the list of references/works cited in the separate window and be taken to the location of the text citation in the Editor Window.  
         [0173]     The program could generate an electronic file with all the unique citations in all SGML/XML documents in the directories specified by the user and provide an interface that lets the user easily insert existing citations in new documents.  
         [0174]     Additional Document Types:  
         [0175]     Support for other types of documents to be determined can be added to the product, as discussed below.  
         [0176]     School-Related Documents:  
         [0177]     Examples of school-related documents that could be supported include:  
         [0178]     Club Newsletter; Literary Magazine; School Newspaper; Student Web site; and Yearbook.  
         [0179]     Personal Correspondence Document Types:  
         [0180]     Personal Correspondence Document Types could also be supported, for example:  
         [0181]     Thank-You Letter; Letter to a Friend; Letter to a Relative; Holiday Gift List; Party Invitation; and Greeting Card.  
         [0182]     Email Document:  
         [0183]     An Email Document (HTML document type) could be added to enable students to author email using their favorite invention graphic user interface.  
         [0184]     A personal journal/web log Document Type can be added to enable students to author a personal journal/web log using their favorite invention graphic user interface.  
         [0185]     Additional Educational Content:  
         [0186]     More educational content can be added:  
         [0187]     Users could choose a “Flash Card” feature to display a new “tip” or “hint” every time they start up the invention. Users could choose the subject matter: capitalization, grammar, punctuation, spelling, etc. Students who consider the subject matter unpleasant may find it more palatable in small bites.  
         [0188]     For daily vocabulary building, Merriam-Webster&#39;s Word of the Day at http://www.m-w.com/cgi-bin/mwwod.pl, which features a new vocabulary word every day, could be displayed in a browser whenever the student starts the invention.  
         [0189]     Additional Tools:  
         [0190]     New tools and features can be added, depending on the Document. For example:  
         [0191]     A Rhyme Minder can be added to Poetry Documents to check the rhymes in poems and to suggest rhyming possibilities.  
         [0192]     A Proof Reader tool could be added to read the paper aloud (using text-to-speech technology) while the student follows the text onscreen or in a printout.  
         [0193]     Depending on the capabilities of text-to-speech technology, a School Play could be read aloud using different voices for the different roles as selected by the user. This is possible because in the invention School Play Document, the roles, stage directions, acts, scenes, etc. will be identified by tags.  
         [0194]     A document differencing feature can be added to the College/University Edition, using Arbortext Editor&#39;s Compare.  
         [0195]     Additional Reference Materials:  
         [0196]     Other reference materials can be added to the online Help for the Research Paper Document. For example, excerpts from handbooks on research and statistical methods could be included. As new citation styles are added, reference materials for the newly supported academic disciplines can be added.  
         [0197]     Additional Languages:  
         [0198]     Arbortext Editor supports many languages, as shown in the following list:  
         [0199]     1. Arabic  
         [0200]     2. Catalan  
         [0201]     3. Chinese (simplified)  
         [0202]     4. Chinese (traditional)  
         [0203]     5. Czech  
         [0204]     6. Danish  
         [0205]     7. Dutch  
         [0206]     8. English (UK)  
         [0207]     9. English (US)  
         [0208]     10. Finnish  
         [0209]     11. French  
         [0210]     12. French (Canadian)  
         [0211]     13. German  
         [0212]     14. Greek  
         [0213]     15. Hebrew  
         [0214]     16. Italian  
         [0215]     17. Japanese  
         [0216]     18. Korean  
         [0217]     19. New Norwegian (Nynorsk)  
         [0218]     20. Norwegian (Bokmål)  
         [0219]     21. Polish  
         [0220]     22. Portugese  
         [0221]     23. Portugese (Brazilian)  
         [0222]     24. Russian  
         [0223]     25. Spanish  
         [0224]     26. Swedish  
         [0225]     27. Swiss German  
         [0226]     The program can be made available in these languages and marketed throughout the world.  
         [0227]     Additional Links to Internet Resources:  
         [0228]     Links to Internet resources such as the WordNet Dictionary can be added.  
         [0229]     Hyperlinks:  
         [0230]     A tag can be added to the Document Types that would treat the text in the tag as a URL. Students could include URLs in their papers so that teachers could review the papers in the invention and link to the Internet sites to quickly verify references to online sources.  
         [0231]     ISBN/ISSN-Based Citations:  
         [0232]     ISBN and ISSN numbers are used to identify most books and serials. It may be feasible to support an online feature that allows users to type in an ISBN or ISSN number that the Bibliography Magician would decode into text surrounded by the appropriate tags. Users would have to enter the specific page number(s) referenced. Bowker maintains the ISBN database and publishes it as Books in Print which can be accessed via Bowker&#39;s online service.  
         [0233]     Text Macros:  
         [0234]     Arbortext Editor supports SGML/XML text entities which allow the user to define a text string as a macro. To change every occurrence of the string, only the macro definition must be changed.  
         [0235]     Abbreviation/Acronym Wizard:  
         [0236]     A Wizard could be provided to properly handle abbreviations and acronyms. Abbreviations and acronyms can be presented in one of two styles, depending on the academic discipline:  
         [0237]     1. For the first occurrence, the spelled out term is followed by the abbreviation or acronym in parentheses; for example, “Modern Language Association (MLA).” For subsequent occurrences, just the abbreviation/acronym is used.  
         [0238]     2. For the first occurrence, the abbreviation/acronym is followed by the spelled out term in parentheses; for example, “ICs (integrated circuits).” After that, just the abbreviation/acronym is used.  
         [0239]     One or more tags for abbreviations/acronyms can be added to appropriate Document Types. When the first abbreviation/acronym tag is inserted, the user would be asked to supply the abbreviation/acronym and the complete term. Then the tag can be inserted, copied, cut, pasted, deleted and moved around without regard for what comes first. When the Document is previewed and printed, the abbreviation/acronym will be correctly presented according to the style selected by the user.  
         [0240]     Auto Outline:  
         [0241]     A feature could be added to automatically create a dynamic outline of a Document from the title tags for divisions such as chapters, sections, subsections, etc. When the text in a title tag changes, the next preview or print would show the updated outline with the new title text.  
         [0242]     Auto Summary:  
         [0243]     An auto summary feature could be added. Artificial intelligence for automatic summarization could be combined with the real intelligence provided by SGML/XML tags to create a better auto summary than what is available with existing word processors.  
         [0244]     Main/Sub Documents;  
         [0245]     Arbortext Editor supports SGML/XML file entities which allow the user to easily create a main document that references subdocuments. This feature is useful for long documents, such as theses and dissertations.  
         [0246]     Change Bars:  
         [0247]     A change bars feature can be added to the College/University Edition of the invention. Dissertation committees, for example, would find change bars useful.  
         [0248]     Arbortext Editor already supports change bars. Change markup can be tag pairs or singleton tags that can straddle block elements. Multiple levels of change bars can be supported.  
         [0249]     In the Editor Window, added text can be shown in color, underlined or presented with other formatting that appears only in the Editor Window, not in preview or print.  
         [0250]     In the Editor Window, text in &lt;delete&gt; tags can be collapsed and its presence indicated by a graphic. Text that is deleted can also be displayed with specific formatting in the Editor Window, but neither the text nor formatting will appear in preview or print. It may be possible to use the Docmap view to display only those lines with deleted text.  
         [0251]     TEX Tags:  
         [0252]     Arbortext Editor can interpret TEX coding, so the Research Paper Document in the College/University Edition of the invention can be enhanced by the addition of one or more “TEX tags” for users to enter TEX coding directly. This would allow the user to copy complex equation coding from an existing TEX document and paste it into a Research Paper Document without using Easy Equations. When the user previews or prints the document, the equation appears in the same format as in the TEX document.  
         [0253]     Note that TEX tags are needed in order to import LaTex files with equations. Refer to Import/Export Documents, below.  
         [0254]     Import/Export Documents:  
         [0255]     In addition to the Save As Web Page feature, various import/export features are possible:  
         [0256]     Framemaker, Interleaf, Word. Arbortext Editor currently supports import from Interleaf and import/export from/to Word and Framemaker. This capability can be added once the necessary configuration files are developed for each document.  
         [0257]     Other SGML/XML. Import of SGML/XML files from other products such as WordPerfect can be supported.  
         [0258]     Import/Export of TEX/LaTex files from/to Research Paper Documents can be developed for the College/University Edition. One or more TEX tags (see TEX tags) is required to handle import of equations.  
         [0259]     HTML. HTML documents can be imported and automatically formatted using one of the pre-defined formats selected by the student. Note that these formats would be optimized for paper output, using formatting that is not available with CSS and producing fewer pages than printing from a browser. Additional pre-defined formats for HTML can be added over time.  
         [0260]     ASCII. The HTML file generated by File→Save As Web Page can be stripped of HTML markup to create an ASCII version of a Document that includes generated numbering, symbols and text, but no formatting except spaces and line breaks. Note that symbols would be limited to ASCII or extended ASCII characters. Simple tables would be formatted using spaces and line breaks, but complex tables would be problematic. Graphics would appear as “Graphic Name Here.” It may be possible to convert simple equations into properly formatted ASCII text. Complex equations would appear as “Equation Number Here.” 
         [0261]     Specific Page Count:  
         [0262]     ACL and FOSI coding can be combined to format documents such as Book Report and Term Paper to fit the number of pages specified by the user.  
         [0263]     Save As SGML/XML:  
         [0264]     Arbortext Editor supports Save As SGML and Save As XML to save XML as SGML and vice versa. This capability can easily be provided.  
         [0265]     Include/Exclude Sections:  
         [0266]     Arbortext Editor supports SGML marked sections which identify text to be included in or excluded from preview and print. This functionality could be added to the Research Paper Document.  
         [0267]     Output to PDF:  
         [0268]     Arbortext Editor supports output to PDF, including PDF and URL links. This feature can easily be enabled.  
         [0269]     Student Document Tracking:  
         [0270]     The program could provide a document tracking feature designed especially for students. For example: File→Track Documents, File→Close and  
         [0271]     File→Exit could provide an interface to track documents worked on in that session. Students could:  
         [0272]     designate each document as “final” or “draft” with a draft number and/or date;  
         [0273]     establish due dates for draft and final versions;  
         [0274]     designate a document as “submitted” and record the date of submission;  
         [0275]     enter the grade received on each paper; the invention could respond with grade-specific spoken messages (for example, entering an “A” could cause the software to respond with “Congratulations!”); and  
         [0276]     enter any notes about the paper, for example, if it contains a frequently used citation that could be copied and pasted into a future paper  
         [0277]     Each draft and final version could be uniquely named and saved in a separate archive directory so that any particular version could be easily restored at any time.  
         [0278]     Document tracking would have different functionality and styling for the College Prep Edition and the College/University Edition. In both editions, this feature could be turned on and off at the Preferences level.  
         [0279]     Homework Joke of the Day:  
         [0280]     Students could set Preferences to see or hear a new joke about homework whenever they start the software. Users would provide the content by submitting their jokes on the Web site. Those who submit jokes could feel particularly motivated to upgrade to each new release so they could see if their submissions were approved for inclusion in the product.  
         [0281]     Bibliography Database  
         [0282]     For serious researchers, a bibliography database feature could be added to the College/University Edition that would enable students to copy citation information from a web site and “paste” it in a database. The database would include links to web sites so citations can be verified at a later date. Students would also be able to enter information directly into the database. Users would be able to click on citations in the database and have them automatically inserted in the proper tags in a Research Paper document.  
         [0283]     Database searching and reporting features could also be provided.  
         [0284]     Table Templates:  
         [0285]     Pre-formatted templates for table layouts used in various scholarly disciplines.  
         [0286]     Commenting Feature:  
         [0287]     A commenting feature that enables students to add comments in the document such as “Verify this quotation” that can be toggled on and off in the screen display and draft prints but will not appear in final printouts. A report can be generated that lists all comments in the document.  
         [0288]     Editorial Assistant:  
         [0289]     An Editorial Assistant feature will provide useful information regarding conventions used in the various Document Types. For example, in Document Types such as Essay and Research Paper, abbreviations such as “i.e.” will be detected real-time or during a batch Check Document process. A dialog will:  
         [0290]     alert the user to the meaning and correct usage of it and similar abbreviations such as “e.g.”;  
         [0291]     advise when the spelled-out phrase is preferred to an abbreviation; and  
         [0292]     enable insertion of the correct form of the desired abbreviation or phrase.  
         [0293]     Preferences settings will control this feature.  
         [0294]     Clip Art Organizer:  
         [0295]     A clip art organizer with a library of graphics pertinent to student documents should be added to the product to increase its user-friendliness. Each new release of the software would include new graphics.  
         [0296]     Spoken Messages:  
         [0297]     The product could support spoken messages in addition to displayed messages. Spoken messages seem especially appropriate for younger users.  
         [0298]     Hands-Free Operation:  
         [0299]     Arbortext Editor currently responds to some spoken commands using a speech recognition software product. As speech recognition technology improves, a hands-free version could be pursued to widen accessibility. Spoken commands seem natural with the invention&#39;s menu-free graphical user interface.  
         [0300]     Touch-Screen Operation:  
         [0301]     To widen accessibility, touch-screen operation will be investigated as a potential replacement/supplement for a mouse device. The invention&#39;s menu-free graphical user interface is especially well-suited to touch-screen operation, especially compared with traditional menu-based products such as Microsoft Word.  
         [0302]     Field of Study Editions:  
         [0303]     Editions can be packaged according to the field of study. For example, the following editions could be created with the appropriate electronic reference materials and links:  
         [0304]     Medical Edition with a medical spelling dictionary; and  
         [0305]     Legal Edition with a legal spelling dictionary.  
         [0306]     Early Grades Edition:  
         [0307]     An edition for younger children could also be provided.  
         [0308]     Citation Editions.  
         [0309]     Some college/university students need only Turabian/Chicago style, some need both MLA and APA while others need Turabian/Chicago, MHRA, and MLA. New editions can be created by packaging together related citation styles and pricing them accordingly. One possibility is a Humanities Edition with Turabian/Chicago, MHRA, and MLA.  
         [0310]     Language Editions:  
         [0311]     Multilingual editions can be created for different regions of the world, for example:  
         [0312]     Canadian Edition—English/French  
         [0313]     Asian Edition—Chinese/Japanese/Korean  
         [0314]     Companion Products:  
         [0315]     Companion products that are SGML/XML-based can be developed to complement the invention. Students deserve software that meets their special needs. SGML/XML technology enables seamless sharing of the same tagged information.  
         [0316]     Student Calendar:  
         [0317]     An online Calendar feature based on a school year with semesters, semester breaks, etc., could be provided to enable students to easily plan and schedule their time. University-specific editions could easily be developed.  
         [0318]     Desktop Suite:  
         [0319]     A Desktop Suite can be provided so users do not need Microsoft Office or its components. A Desktop Suite would minimally include presentation and spreadsheet software in addition to the word processor and above-described Student Calendar.  
         [0320]     For example, a title, paragraph and bullet-list (tags and text) could be copied from a word processing Document and pasted into a presentation. In the presentation, the pasted text would be formatted according to the stylesheet in effect. As with the word processor, the formatting for a presentation could be changed at any time simply by selecting a different stylesheet.  
         [0321]     The word processor and presentation software could be combined into one product sharing the same .sgm/.xml files without the need for importing or conversion. New Document Types for correspondence, professional reports, etc., are also possibilities so users do not need any other word processor software.
