This booklet constitutes the completely refereed post-workshop court cases of the ninth overseas Workshop on Mining internet info, WEBKDD 2007, and the first foreign Workshop on Social community research, SNA-KDD 2007, together held in St. Jose, CA, united states in August 2007 along with the thirteenth ACM SIGKDD overseas convention on wisdom Discovery and information Mining, KDD 2007.

The eight revised complete papers awarded including an in depth preface went via rounds of reviewing and development and have been rigorously chosen from 23 preliminary submisssions. the improved papers deal with all present concerns in net mining and social community research, together with conventional net and semantic internet purposes, the rising purposes of the net as a social medium, in addition to social community modeling and analysis.

To compute S , we must first scale and normalize 46 G. Creamer et al. each of the previous statistics which we have gathered. The contribution, C, of each metric is individually mapped to a [0, 100] scale and weighted with the following formula: wx · Cx = wx · 100 · xi − inf x sup x − inf x where x is the metric in question, wx is the respective weight for that metric, the sup x and inf x are computed across all i users and xi is the value for the user. This normalization is applied to each of the following metrics: 1.

Unlike previous IBM Jams where preparation was not necessary, the Jam required familiarization with emerging technologies which were described in online materials made available to participants prior to the event. Individual contributions to the Jam came in the form of “postings,” or messages in reply to other contributors and to questions posed under a moderated topic area. As shown in Figure 1, groups of such postings are defined as “threads”. For five weeks following Phase 1 of the Innovation Jam, a multi-discipline, international cross-IBM team analyzed more than 37,000 Phase 1 posts to identify the most promising suggestions, resulting in 31 identified topics or “big ideas” as listed in Table 4.

O1 Average pairwise distance between the contributors within a big idea 4 . O2 Standard deviation of the pairwise distances between the contributors 4 . O3 Total number of pairwise distances between all the contributors involved. O4 Maximum pairwise distance between the contributors. O5 Minimum pairwise distance between the contributors. 046 Table 3.
