1. Rating Scales for Collective Intelligence in Innovation Communities Why Quick and Easy Decision Making Does Not Get it Right > Christoph Riedl IvoBlohm Jan Marco Leimeister Helmut Krcmar
12. Dimensions of Idea Quality An idea‘s originality and innovativeness Ease of transforming an idea into a new product An idea‘s value for the organization An idea‘s concretization and maturity Source: [1, 2, 3]
14. Research Model Judgment Accuracy Rating Scale H1+ Rating Satisfaction H2+ H1: The granularity of the rating scale positively influences its rating accuracy. H2: The granularity of the rating scale positively influences the users' satisfaction with their ratings.
15. Research Model User Expertise Judgment Accuracy H3a Rating Scale H1+ Rating Satisfaction H2+ H3a: User expertise moderates the relationship between rating scale granularity and rating accuracy such that the positive relationship will be weakened for high levels of user expertise and strengthened for low levels of user expertise.
16. Research Model User Expertise Judgment Accuracy H3a H3b Rating Scale H1+ Rating Satisfaction H2+ H3b: User expertise moderates the relationship between rating scale granularity and rating satisfaction such that the positive relationship will be strengthened for high levels of user expertise and weakened for low levels of user expertise.
26. Research Design Promote/Demote Rating 5Star Rating ComplexRating
27. So much for the data space and its attributes. Next, we have to think about who our users are and what they want to do. All lifelogging applications are first of all about 5. Results
33. ANOVA Results N = 313, *** significant with p < 0.001, ** significant with p < 0.01, * significant with p < 0.05
34. ANOVA Results Post-hoc comparisons: Complex rating scale leads to significantly higher rating accuracy than promote/demote rating and 5-star rating (p < 0.001)
35.
36.
37. Regression Results There is no direct and no moderating effect of user expertise. The scale with the highest rating accuracy / rating satisfaction should be used for all user groups.
38. Correlations of Expert Rating and Rating Scales Additional Slide (not partofthepresentation)
44. Design and test of a model to analyze the influence of the rating scale on rating quality and user satisfaction.
45.
46. Simple scales have low rating accuracy and low satisfaction Design recommendations for user rating scales for idea evaluation
