These activities are collected in an activity log, (e.g. Facebook Wall, Google+ Stream, etc.) on the user’s social network profile.

There is also some overlap with Discussion 67 (1979) on State-Selected Kinetics and Discussion 75 (1983) on Intramolecular Kinetics. However, the present symposium di†ers from all these in two very important ways : (1) condensed-phase reactions are also included, and (2) the discussion is focused exclusively on theory. With these aspects in mind one could include a number of earlier predecessor...

In this paper, we investigate generating a set of query-focused summaries from search results. Since there may be many topics related to a given query in the search results, in order to summarize these results, they should first be classified into topics, and then each topic should be summarized individually. In this summarization process, two types of redundancies need to be reduced. First, ea...

How can we succinctly describe a million-node graph with a few simple sentences? Given a large graph, how can we find its most ‘important’ structures, so that we can summarize it and easily visualize it? How can we measure the ‘importance’ of a set of discovered subgraphs in a large graph? Starting with the observation that real graphs often consist of stars, bipartite cores, cliques and chains...

One often overlooked challenge is determining the best way to report those disparities associated with multiple attributes such as income, education, sex, and race/ethnicity. This article proposes an analytical approach to summarizing social disparities in health, and we demonstrate its e...
