We use a four-pronged approach to analyze comments on the previous presentation "Comments on SlideShare: Their Mapping and Value-Added". The approaches are: 1- Timeline flow of comments 2) Clustering of comments 3) Social network analysis of commentators and 4) The spiral growth of comments' structure. Initial comments and their value have a big effect on subsequent comments and activities.

1. Comments in SlideShare: A Four-Pronged Study of Their Impact Ali Anani and Bas de Baar

2. Before A previous publication on “Comments on SlideShare: Their Impact and Value-Added” triggered more comments. The richness of comments triggered the publication of their detailed analysis using a four-pronged approach.

3. Techniques and Tools

4. Analysis of Comments Twenty comments were recorded over a ten days time span. These comments were recorded. A summary of these comments in their chronological order is shown in the next slide

5. Summary of Twenty Comments

6. Classification of Comments We used NeuroXL Classifier software to analyze comments and classify them in four clusters. Since the previous publication on comments on SlideShare used a quadrant, we opted to classify comments into four clusters to standardize the approach.

7. Four Clusters of Comments To be able to classify comments into four clusters we had first to turn the twenty judgmental comments into values. We did this by assigning the following values: High 8 and above Medium >6 and <8 Low <5 The results are shown in the next slide

8. Clusters of Comments

9. Clusters 1 and 2 Clusters 1 and 2 share the starting value of low-impacting comments. However; the two clusters have opposite paths. When one cluster is low the other cluster is high. Initial comments with low impacting value mostly end up having low or very moderate outcomes.

10. Clusters 3 and 4 Clusters 3 and 4 share having a high-impacting value at their initiation. They both end up having high impact on commentators. Initial high-value comments may lead to building new relations, generating new publications and opening new social structures. As we have a case in which the initial comment carried weight we decided to follow its impact over a ten-days period.

11. Analysis of Relation Build-up The comments and responses to them created new relationships among commentators. The next slide shows the resulting network structure. The darkness of the connecting lines is directly proportional to the strength of relationships among commentators. Faint lines indicate weak ties.

12. Social Network Structure among Commentators.

13. Statistics of Social Network Structure We used NodeXL software to analyze the emerging structure. The next few slides highlight the important statistics for those readers who might be interested.

14. General Statistics

15. More Statistics on the Resulting SNA

16. The Spiral Structure of Comments We used Goalscape software to study the spiral build-up of comments. Comments grow naturally and may have a spiral-like structure.

17. Initial Structure The main goal (highlighted in yellow) is surrounded by three daughter goals.

18. Explanation of the Initial Structure George Sciberras (xiby) made the first comment. Xiby emphasized the need for balanced feedback of comments. This comment invited for many more comments, Starting with a “diamond” comment may bring more valuable comments, or may stop later commentators from making comments for fear they would not match the first one. It is a two-edged sword.

19. Role of Subsequent Commets Anani drew attention to the harmful side effects of some comments Xiby highlighted the need to encourage new authors, and especially those who do not master the English language Anani concurred with xiby that tired minds nee light presentations

20. Outcome of Comments Prabakar supported Sheereen’s idea that collective minds work better that a single mind. Comments are the work of mind network These comments spurred Anani to write this presentation with Bas de Baar

21. Subgoals of Daughter Goals- Building the Spiral Structure

22. Good Comments Invite for More Prabakar advanced the idea of three dimensional evaluation of ideas Anani welcomed the idea, but showed concern that not all people are happy with three dimensional analysis Juao Maya decided to reevaluate his presentations prior to their publication projectShrink and three other sites embedded the presentation

23. Deferred Outcomes Anani and Prabakar decided to publish a joint presentation for SlidsShare Anani and bas de Baar will work together to expand the use of spiral structures

24. Third Level of the Spiral Structure

25. The Momentum of Comments Is Rising These comments reflected increased intensions for working together and reinforcing the social network structure of the participating commentators
