CPoint Installation

• The CPoint PowerPoint Add-In can be installed by
  clicking
• Tools
• Add-Ins
• Add New
• And selecting CPoint.ppa (and OK the forms) .

12
CPoint Version 0.9.4 New Features (I)

• New Features
• Installation Without Premises CPoints
  installation is now independent of the
  MSXML-library ? the import feature was placed
  into a separate CPoint module CPointImport

13
CPoint Configuration (CPoint.ini)

• CPoints Configuration data
• is handled by
• CTools ? CPoint Manager
• is stored in
• the CPoint.ini file.
• The location is predetermined to be
  C/CPoint.ini
• (as most users have the right to write on that
  drive).
• If no CPoint.ini file is found by the CPoint
  Manager, it will create a default one.

14
CPoint Goal

• What is it for?
• The objective of CPoint consists in the
  conversion of the content of a PowerPoint
  presentation to the semantic, XML-based data
  format OMDoc e.g. as input for computer-supported
  education systems like ActiveMath.

15
CPoint PPT Content

• What is the content of a PPT show?
• (Obviously,) the text and pictures (generally the
  objects themselves)
• The given textual, presentational, and
  placeholder structure
• Grouping of objects

16
CPoint Semantic Markup

• Semantic Markup of objects
• The quality of content is much higher if it is
  categorized. Naturally, this has to be done
  (mostly) manually.
• The categorization provides additional
  information for each object.
• The semantic markup information can be
  manipulated with CPoint

17
PowerPoint Document Structure

• The top-level structure of a PowerPoint
  presentation is given by slides.
• Each slide contains objects, e.g.
• Textboxes
• Shapes
• Images
• Tables

18
PowerPoint Object Properties

• An object is assigned certain properties like
• text structure, e.g.
• Lists
• Ordered lists
• Unordered lists
• Or presentational structure, e.g.
• Colors, bold fonts, italic fonts
• Or a special predefined placeholder slot, e.g.
• Title
• Subtitle

19
PowerPoint Additional Information

• Within a slide the user can group objects.
• Press the Shift button and select objects (at
  least two and no title object)
• Rightclick and select Grouping ? Group

• Every object can store additional information
  with the help of a VBA (Visual Basic) program.

CPoint
20
CPoint Architecture

• CPoint is
• a collection of VBA macros which allow the user
  to semantically markup slide objects.
• A conversion tool to migrate the content of a
  PowerPoint presentation (either annotated
  information or intrinsic structure) to other data
  formats like OMDoc. And from here to HTML or HTML
  Slides.
• A connection tool to other applications

21
CPoint Objects
First, let us determine our terminology

• Object
• Any element in a PowerPoint show
• PPT Object
• Any element in a PowerPoint show pertaining to
  its presentation
• Abstract Object
• Any element of a PowerPoint show not pertaining
  to its presentation. These are created by the
  CPoint Macros in behalf of the semantic markup.
  They can be changed from visible to invisible via
  Visualize button.
• Semantic Object
• Any annotated PPT object or abstract object.
• Theories, Definitions, Assertions, ProofSteps,
  Examples, and Exercises are considered the main
  semantic objects.
• These are universal, interdisciplinary terms even
  though they sound mathematical (see the main
  semantic objects model)!

22
CPoint Collections

• A (CPoint) collection is a group of PowerPoint
  presentations with an associated internal
  namespace. Each presentation has a collection
  wide unique id. Once a presentation is contained
  in a collection, CPoint has access to it. With
  the CPoint manager the user can define
  collections.

23
CPoint Overview Semantic Markup

• Categorize
• Categorize the objects e.g. as example or theorem

• Restrict search space by
• object name,
• category,
• presentation,
• text (Title or CPoint Data, Match Case)
• Semantic or non-semantic.

29
CPoint The Navigator Button Scope

• The value of the Navigator Button for Selection
  Boxes determines the scope of the elements in the
  adjoining selection box.
• Possible Values are
• Home theory
• Imported theories
• Local presentation
• Abstract object
• Collections
• MBase (still to come)

30
CPoint The Navigator Button Navigating

• The Scope Order is defined to be
• H lt I lt L lt A lt C lt M
• The Navigator Button allows 3 actions
• Clicking
• Moves the scope one up and starts at the
  beginning if being at the end.
• DoubleClicking
• Moves the scope one down and goes to the end if
  being at the start.
• RightClicking
• Opens a Search Restriction Interface (if
  available) or creates an abstract object (if
  scope A)

31
CPoint The Navigator ButtonSearch Restriction
by Categories
AbstractObject2
Manipulate the selection in the adjoining
selection box by using the Search Restriction
Interface for Categories, I.e. restrict the
search space by filtering those objects out which
category wasnt selected.
In this example the categories assertion and
axiom are selected, a search will deliver all
assertion and axiom objects of the current
presentation in the respective combo box in the
calling form.

CPoint How To Categorize (I)

• Select one object

• Click the Categorize button

• Decide whether the object is a sequel.

• If not
• - Decide on the didactic role.
• - Rightclick the Categories box.
• - Select a
• category.

• Create a title and save this information for this
  object!
• The information is NOT stored in a database but
  directly with the object. As a consequence a copy
  of this object also copies all its data and even
  the object name (which might lead to CPoint
  malfunctions).

35
CPoint How To Categorize (II)

• What else is there besides categories?

? Determine the Content Type

• ? Decide on the content type details

• Have a look at the already supplied meta- and
  content information
• or create or modify it

Finding the Right Category

• Category categorization and role assignment
• Finding the best correct category is not as
  easy as you might think (e.g. there are lots of
  correct categories to choose from).
• Restrict yourself first to the content categories
  as finding the most important categories first
  is easier.
• ? Look for the main semantic objects!

Categorization Process

• Find the theories and categorize them, determine
  their range (largest main semantic objects).
• Find the existing symbols, then define or declare
  them (smallest main semantic objects).
• Find the assumed theories and symbols, import the
  according theories in the resp. theory details
  form.
• Pick the PPT objects you can clearly identify as
  semantic objects and categorize them accordingly
• (intermediate main semantic objects).
• By now you have a starting list of the main
  semantic objects.
• Try to find the semantic objects they belong to.
  If you cant find it, decide whether you need to
  create an abstract object for this superordinate
  concept.
• Categorize the remaining PPT objects with their
  according assignment to a semantic object if
  sensible.

42
CPoint Content Forms

• How do I provide more content to a PPT object?
• Select ONE PPT object
• Click the Content button
• Depending on the categorization the user can
  supply additional information for the selected
  object.

• What else?
• Update basic information title and description
• Check or update the meta information

• Comment this object (e.g. write down the things
  you say when giving the talk)

Content Reference System

• Some objects relate to other objects,
• e.g. an answer should belong to a certain
  question, but it should not pertain to a code
  object.
• Those relationships are explained in more detail
  on the following slides

45
Content Reference System Theory and Primitive
Symbols

• A theory is a collection of concepts and their
  properties. It can cover any kind of object.
  Definitions, axioms, and assertions must either
  have an assigned theory or a covering theory.
• The theory area is determined by a given slide
  range All objects on the slides in the given
  range belong to this theory. Theory ranges may
  not overlap.
• Primitive Symbols can be created from within a
  theory details form or manually. Often, in a PPT
  presentation concepts are not defined, but rather
  introduced by their properties (stated in axioms).

46
Content Reference System Definition and Defined
Symbols

• A definition always defines a symbol. The user
  doesnt have to select a PowerPoint object for a
  symbol. It is created on request from within the
  Definition content form if it doesnt exist yet.
  Several symbols maybe defined by one definition.
• A symbol belongs to a definition and is thereby
  assigned a theory. The content form of a
  definition object will list all (defined) symbol
  objects for it. Similarly, the content form of a
  theory will list all the defined symbols
  belonging to this theory.

47
Content Reference System Symbol Declaration
Symbol name may not contain spaces
For a defined symbol the theory is inherited from
the definitions theory

Content Reference System Assertion and
ProofSteps

• An assertion may have an assigned proof.
• The proof may consist of several proof steps.
• The first of these should reference the
  assertion, which it will prove (it is therefore
  called the proof).
• Each subsequent proof step has to reference a
  preceding one to complete the proof.

52
Content Reference System Example

• An example is an object (likely a symbol)
  together with a property (for which it is an
  example for, e.g. definition or assertion) and a
  statement relating the object and the property.
• For instance 4 is an even number.
• The integer 4 is the object.
• The property is even or even number.
• The statement is the sentence.
• Usually, the statement will be considered the
  example, but the real object is the one
  described in the statement and this object should
  be referenced within the content form.

53
Content Reference System Exercise Solution -
Hint

• An exercise can be accompanied by one or more
  hints for solving it or even a solution. Clearly,
  these belong together.
• Therefore a solution or a hint object can
  reference an exercise.

54
CPoint Metadata

• The metadata form allows the user to input
  metadata according to the Dublin-Core standard
• (http//dublincore.org).
• The default language is English, but if you
  declare the custom tag language for the PPT show
  (in the properties), then this will be taken.
• LastUpdate Dates are updated
• when an object is annotated or annotailed,
• But not automatically when metadata are updated.
  This allows the user to update dates manually.
• Creators and Contributors can be added by
  overwriting the current text and either using the
  enter key or leaving that input field.

55
CPoint Convert To OMDoc (What is it?)

• CPoints Convert To OMDoc is a conversion macro
  
• PowerPoint (PPT) ? OMDoc

• OMDoc is an XML-based interlingua for
  mathematical communication.
• See http//www.mathweb.org/omdoc for more
  information.
• OMDoc is used in computer-assisted education
  systems like ActiveMath and searchable
  mathematical databases like MBase
• (see http//www.activemath.org
• and http//www.mathweb.org/mbase respectively).

56
CPoint Convert To OMDoc (What does it?)

• If an object is assigned a category ( role),
  then that information will be used to create an
  OMDoc element for it (in the OMDoc file). The
  intrinsic structure (given by PowerPoint) is
  preserved as much as possible.
• If an object is not assigned a role, the best-fit
  OMDoc structure will be heuristically determined
  by CPoint honoring the possibly annotated (
  assigned in categorize form) content type.

57
CPoint Convert To OMDoc (Input)

• PPT presentation
• Linked images
• If the PPT presentation contains linked images,
  the user will be asked whether the program shall
  break the link or not (naturally just for the
  OMDoc document). If the link is kept, then the
  linked image should be made available. Its path
  information in the resulting OMDoc is the same as
  it was in the PowerPoint presentation. If it was
  relative, then it might be wrong in the OMDoc
  (check it!).

58
CPoint Convert To OMDoc (Output)

• ../capsule/ltPPT namegt.omdoc
• If the folder ../capsule doesnt exist, it will
  be created.
• JPG-files for objects used in the presentation
• One copy of each slide as JPG-file

59
CPoint Convert To OMDoc (Fonts)

• For the creation of special symbols like
  a(alpha) there are (at least) two ways to go
  in PPT
• Using the Symbol Font
• Using Insert Symbol with a specified font, e.g.
  Symbol
• These have different effects on the OMDoc output
• OMDoc output as OpenMath object with reference to
  a migration theory Symbol
• OMDoc output as character reference (e.g.
  x3B1). Depending on the font this character
  reference might or might not be a Unicode
  character reference!

60
Where Not to Use Categories

• On the following slides we supply examples for
  PPT objects which carry content by themselves.
• Categorizing these objects might result in
  information loss
• charts
• tables
• embedded OLE objects

The red box indicates the category in each
example and is itself categorized as Warning!
61
Example Chart
No category!
If you categorize a chart, then the chart
information is lost to the OMDocize macro.
62
Example Table
No category!
If you categorize this object, the table
structure is lost.
63
Where to Use Categories

• On the following slides we give categorized
  examples
• Please, dont use the ResetAll button
• on this documentation (as this results in the
  destruction of the example annotations). Dont be
  scared now if you accidentally hit the button,
  you will be asked for confirmation!
• ResetAll is helpful for learning the
  categorization process.
• Please, use the other buttons!
• We recommend not to save these changes as they
  might be inconsistent with the adjoining text.

The yellow box indicates the category in each
example and is itself categorized as Comment!
