Abstract

The facts module of VISO defines vocabulary for stating facts from (empiric) visualisation research.

This module contains vocabulary to state facts from (empirical) visualisation research, but not the facts themselves. This choice was made, to allow for easy exchange of the fact base. See http://purl.org/viso/facts/empiric/ for our collection of such facts, collected from literature.

Classes

Graphic Design Criterionc

http://purl.org/viso/facts/Graphic_Design_Criterion

Rankings can be done for graphic design criteria such as effectiveness and expressiveness.

  • »The codification of graphic design criteria in a form that can be used by the presentation tool [...] The graphic design issues are codified as expressiveness and effectiveness criteria for graphical languages. «

Object Properties

:appropriate_to_visualizeop

http://purl.org/viso/facts/appropriate_to_visualize

has super-properties

States that a visual means is not only expressive enough to encode some data classification type (such as ordinal data), but that is also appropriate/acceptable/suitable to encode it. The appropriateness criteria and the facts given in this data set are based on the the Figure "Fig. 3-26" in: J��rg Engelhardt, von, ���The Language of Graphics��� (Institute for Logic, Language & Computation, University of Amsterdam., 2002). This is in turns based on a figure from MacEachren (p. 272) in: A. M MacEachren, How maps work (Guilford Press New York, 1995).

:appropriate_to_visualizeop

The expressiveness criteria and the facts given in this data set are based on the the Figure "Figure 25 - Expressiveness of Retinal Techniques" (p. 130) from Jock Mackinlay in ���Automating the design of graphical presentations of relational information���, ACM Trans. Graph. 5, Nr. 2 (1986): 110-141 .

Example

Visual means "A" expresses "Nominal Data" means that "A" can express nominal data. It does not state something on how well it is suited for this purpose or how effective it is.

Data Properties

:has_effectiveness_ranking_for_nominal_datadp

http://purl.org/viso/facts/has_effectiveness_ranking_for_nominal_data

has super-properties

Assignes an (ordinal) effectiveness value for encoding nominal data to a visual means. A visual means with a higher number is more effective than one with a lower number.

cf. example of superproperty

:has_effectiveness_ranking_for_ordinal_datadp

http://purl.org/viso/facts/has_effectiveness_ranking_for_ordinal_data

has super-properties

Assignes an (ordinal) effectiveness value for encoding ordinal data to a visual means. A visual means with a higher number is more effective than one with a lower number.

cf. example of superproperty

:has_effectiveness_ranking_for_quantitative_datadp

http://purl.org/viso/facts/has_effectiveness_ranking_for_quantitative_data

has super-properties

Assignes an (ordinal) effectiveness value for encoding quantitative data to a visual means. A visual means with a higher number is more effective than one with a lower number.

cf. example of superproperty

:has_effectiveness_ranking_valuedp

http://purl.org/viso/facts/has_effectiveness_ranking_value

This property only serves as an "abstract" convenience container for the more specific properties that allow assigning effectiveness values to nominal, ordinal and quantitative data. The effectiveness criteria and the facts given in this data set are based on the the Figure "Fig. 15 - Ranking of Perceptual Tasks" (p. 125) from Jock Mackinlay in ���Automating the design of graphical presentations of relational information���, ACM Trans. Graph. 5, Nr. 2 (1986): 110-141 .

Example

If visual means A has an effectiveness value of 4 and visual means B a value of 8, then visual means B is more effective than A for the given kind of data.

Warning: Although the range is float, the ranking value is purely ordinal, i.e. it does not allow statements such as A is 2 times more effective than B. It was therefore also made a subproperty of "has_ordinal_value".
