This e-book constitutes the completely refereed post-workshop lawsuits of the ninth foreign Workshop on Mining internet information, WEBKDD 2007, and the first overseas Workshop on Social community research, SNA-KDD 2007, together held in St. Jose, CA, united states in August 2007 at the side of 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 handle all present matters in net mining and social community research, together with conventional net and semantic net purposes, the rising functions of the internet as a social medium, in addition to social community modeling and analysis.

Ca) in 2006. The brainstorming format within a limited time frame is recognized as a useful approach to dispersed and large-scale collaboration. Thus, it is useful to analyze the discussions, and explore how people reached the resultant “big deas” of the Jam. 3 Innovation Jam Background In 2001, IBM introduced the Jam concept through a social computing experiment to engage large portions of its global workforce in a web-based, moderated brainstorming exercise over three days [8]. What became known as the “World Jam” was eventually followed by six additional internal, corporate-wide Jams, drawing employees into discussions about everything from management to company values.

The three largest threads were selected for analysis, with the first discussing “Sustainable energy systems”, the other on “Digital entertainment” and the third on “Global travel” with 622, 405 and 776 posts respectively. To determine whether a series of posts have a focused discussion or not, we compare the content similarity as well as the number of unique contributors. We preprocess the texts in each post using the bag-of-words representation described before, and then calculate the averaged cosine similarity between 10 adjacent posts in a time-based consecutive order.

The weighted clique score W is computed with the following formula: W = t · 2n−1 where t is the time score for the given user. , vn is the set of vertices, E is the set of edges, and eij is the edge between vertices vi and vj : . – Degree centrality or degree of a vertex vi : deg(vi ) = j aij where aij is an element of the adjacent matrix A of G . 2|{eij }| n – Clustering coefficient: C = n1 i=1 CCi , where CCi = deg(vi )(deg(v : i )−1) vj ∈ Ni , eij ∈ E. Each vertex vi has a neighborhood N defined by its immediately connected neighbors: Ni = {vj } : eij ∈ E.
