To provide solutions to these issues, this paper presents Knowledge Puzzle, a tool for knowledge construction from the Web. Its main contribution to Web-based learning is the personalization of information structure on the Web to cope with the knowledge structure in the learners mind. Self-directed learners will be able to adapt the path of instruction on the Web to their way of thinking, regardless of how the Web content is delivered. The way to achieve that is to provide learners with a meta-cognitive tool that enables them to bring knowledge gained from the Web to the surface and visualize what they have in mind. Once we get the learners viewpoint externalized, it will be converted to a hypermedia layer that will be laid over the Web pages visited by the learner. The attached layer adapts the views of Web pages to the learners information needs by associating information pieces that are not already linked in hyperspace and attaching the learners notes to the page content.

The third one measures the change in normative dependencies like obligations and prohibitions introduced by norms. The fourth one measures changes in coalitions. If one of the first three measures is high, then the fourth measure is probably high too, if the change in agents and dependencies is a cause for a change in coalitions. If the first three measures are low, but the change in coalitions is high, it is due to internal processes like violations of the coalition agreements. }, added-at = {2009-06-16T15:00:02.000+0200}, address = {New York, NY, USA}, author = {Boella, Guido and van der Torre, Leendert and Villata, Serena}, biburl = {http://www.bibsonomy.org/bibtex/2be75d71770ce5214483a919753f381bf/ht09}, booktitle = {HT '09: Proceedings of the Twentieth ACM Conference on Hypertext and Hypermedia}, interhash = {4797aeda13d2cbe6340413329cf0d589}, intrahash = {be75d71770ce5214483a919753f381bf}, keywords = {dependence engineering ht2009 measures networks poster pp158 requirements social}, month = {July}, paperid = {pp158}, publisher = {ACM}, session = {Poster}, timestamp = {2009-06-16T15:00:02.000+0200}, title = {Four Measures for the Dynamics of Coalitions in Social Networks}, year = 2009 }
