1. Infotools Harmoni IHU: Constructions
September 2017 Presented by: Janine Takle

2. Overview Constructions are used to create new items in a project
Items can be constructed using items that already exist in the project, or with user entered values
Once created, constructions are automatically updated when new sources are added
Infotools Harmoni itself is source agnostic

3. Creating Headings

4. Creating Headings
A new heading can be created using add heading in the edit menu
The add heading option is only available if the selected item in the dictionary tree is a single axis or heading
The heading is inserted above the selected item

5. Creating Axes
There are 3 different ways to start creating a new axis … let’s have a look at them

6. Creating Axes
A new axis with elements that already exist in another axis can be created either by selecting and dragging existing elements into space
Elements can only be dragged out to create a new axis when one, or more, elements from the same axis are selected
The new axis will be added to the data dictionary in the position the elements are dragged to

7. Creating Axes
A new axis with elements combined from other axes can be created by using combine items in the construct menu
The created axis appears above the first item selected to be included in the new axis
The combine items option will only create a new axis when there are two, or more, unconstructed axes selected
The ability to apply combine items to constructed axes will be available in upcoming versions

8. Creating Axes
A new axis in which to create your own elements can be created by using new axis in the construct menu
The created axis appears above the item selected
The axis will not be saved into the dictionary until both the axis has a name, and there is at least one named element

9. Creating Elements

10. Creating Elements
Existing unconstructed elements can be combined together into a new element using combine items
The combined element appears above the first item selected for inclusion

11. Creating Elements
Elements can be created in constructed axes using new element in the construct menu
New elements appear below the element selected
After defining an element there is also an option below the definition to add a new element

12. Defining Elements
An element definition defines the condition that must be true for the data records to be included in the element
The expression editor is the interface by which the definition is entered
The expression editor supports both typing and dragging and dropping to build the expression
When typing, the possible options are displayed for selection, use the arrow down key to highlight the option choice, and Enter to select it

13. Defining Elements
An element can be defined using a single Axis.Element condition simply by dragging a single element into the expression editor
Dragging in more than one element from the same axis into the definition assumes an or relationship across elements
Dragging in elements from different axes into the definition assumes an and relationship

14. Defining Elements
An element can be defined using any combination of Boolean Logic, including ands, ors, brackets and nots in the expression editor
And decreases the number of data records being included
Or increases the number of data records being included
Brackets are used to determine the order of calculation
Not is to be used with either and or or

15. Defining Elements Measures can be used in the definition of an element
When using measures, the condition is still identifying the condition that must be true in order for data records to be included in the new element
A comparative operator must be used when using a measure to define an element, i.e. >, <, <=, >=, <>, =

16. Creating Measures

17. Creating Measures
A new measure can be created by using new measure in the construct menu
Measures contain a single value for each respondent
Records to be excluded from the measure’s count need to be assigned a missing value
3.4e38 is Infotools Harmoni’s missing value
Measures can be built using values from other measures, or from values entered explicitly in the definition

18. Creating Measures
An if statement is an effective way of assigning different values to different data records
The syntax for if is:
if(condition, value if true, value if false)
The value assigned to those records that satisfy the if condition (i.e. the condition is true), is different to the value assigned to those that don’t (i.e. the condition is false).

19. Creating Measures
When there are more than 2 different values to assign, more if statements can be nested into the value if false
For example, if we want to assign the Yes elements in the Question axis to have a value of 1, and the No answers a 0, while the Don’t Know responses, and those that didn’t give a response are not to be included in the measure, the syntax would be:
if(Question.Yes, 1, if(Yes.No, 0, 3.4e38))

20. Creating Measures Measures can be defined using calculations, i.e.
addition using +
subtraction using -
multiplication using *
division using /
For example, a Total Alcohol Spend measure could be calculated by adding together the measures Off-License Spend and On- License Spend
Off-License Spend + On-License Spend

21. Creating Weights

22. Creating Weight
A new weight can be created by using new weight in the construct menu
Weights contain a single value for each respondent
Weights are defined using all the same techniques as used for defining measures

23. Tips & Tricks

24. Tips & Tricks Constructions can use items in one or many sources
Both conditions in an and relationship must exist in at least one source, or no records will be included in the construction
Not all conditions in an or relationship need to exist in any one source in order for records to be included in a constructed element

25. Tips & Tricks
The most reliable way of including an item in a complex definition is through typing to display the list of matching labels, then selecting them from the displayed list
When typing the text to match, the possible matches are only displayed when they are similar, not identical

26. Tips & Tricks Related enhancements coming up in the roadmap:
Constructions from constructions
Default weights
Making a constructed weight a default weight
Making a renamed weight a default weight
Weight target matrix

28. Try it yourself

30. Try it yourself…?
Use the sav files for Moon Landing found in
Create a multiple response axis that combines together these axes, then remove the 0 element that contains all the respondents that said 0 (i.e. No) in at least one of contributing axes:

31. Try it yourself…
Combine the age elements together to create fewer categories
Create a new Target Segments axis with the following elements
Frequent Flyer Retirees
= 65+ Years and Visited the Moon more than twice
Coastally Focused Females
= Visited A Beach and A Marine Park/Reserve and not A geothermal park, A glacier, A national park, or Hot pools

32. Try it yourself…
Create an Other Costs measure containing the amount spent that wasn’t on Airfares or Packages, i.e. the amount left after subtracting Airfares and Packages from Total Spend
Create a Demographics heading and move Gender, Age, and Traveller Type into it
Create a Gender Weight that adjusts the gender proportions to 50/50

33. Answers/Hints Try it yourself 3. Other Costs measure
Coastally Focused Females
Frequent Flyer Retirees
2. Target Segments definitions
Try it yourself

34. Answers/Hints
To change this to 50/50 we need to assign all males a weight of (50/45) and all females need a weight of (50/55)
Across all 3 Moon Landing sources, the Male/Female distribution is 45/55
5. Gender weight
