The Impact of Semantic Document Expansion on Cluster-Based Fusion for Microblog Search

Searching microblog posts, with their limited length and creative language usage, is challenging. We frame the microblog search problem as a data fusion problem. We examine the effectiveness of a recent cluster-based fusion method on the task of retrieving microblog posts. We find that in the optimal setting the contribution of the clustering information is very limited, which we hypothesize to...

Comment on "Quantifying Long-term Scientific Impact"

The paper comments on “Quantifying long-term scientific impact”. It indicates that there is a mistake of [D. S. Wang, C. Song, A. L. Barabási. Quantifying long-term scientific impact, Science, 342, 127 (2013)].

Comment on “ Quantifying long - term scientific impact ”

Wang et al. (Reports, 4 October 2013, p. 127) claimed high prediction power for their model of citation dynamics. We replicate their analysis but find discouraging results: 14.75% papers are estimated with unreasonably large m (>5) and l (>10) and correspondingly enormous prediction errors. The prediction power is even worse than simply using short-term citations to approximate long-term citati...

Background for Condensed Cluster Fusion

For explaining the experimentally claimed anomalous excess heat phenomena in metal-D(H) systems, the condensed cluster fusion (CCF) theory has been proposed and elaborated[1-8] since 1989. This paper reviews the latest status of CCF theory development. The paper explains the following key aspects: classical mechanics and free particle fusion, fusion rate theory for trapped D(H) particles, stron...
