Link Prediction of Social Networks Based on Weighted Proximity Measures
TLDR
An improved method for predicting links based on weighted proximity measures of social networks based on an assumption that proximities between nodes can be estimated better by using both graph proximity measures and the weights of existing links in a social network. Expand
Breaking News Detection and Tracking in Twitter
TLDR
An application called “Hotstream” is developed based on the proposed method to collect, group, rank and track breaking news in Twitter, and boosts scores on proper nouns to improve the grouping results. Expand

TLDR
This paper proposes a fast algorithm called LP&BRIM, based on a joint strategy of two developed algorithms -- label propagation (LP), a very fast community detection algorithm, and BRIM, an algorithm for generating better community structure by recursively inducing divisions between the two types of nodes in bipartite networks.

Advanced modularity-specialized label propagation algorithm for detecting communities in networks
A modularity-specialized label propagation algorithm (LPAm) for detecting network communities was recently proposed. This promising algorithm offers some desirable qualities. However, LPAm favorsExpand

TLDR
Experimental results show that the new bipartite modularity proposed by Guimera and Barber allows one-to-many correspondence between communities of different vertex types. Expand
How Does Label Propagation Algorithm Work in Bipartite Networks?

TLDR
This paper investigates a recently proposed community detection algorithm—label propagation algorithm (LPA), and proposes a new algorithm to make it more suitable for bipartite networks, and demonstrates that the new algorithm is more stable than the standard LPA. Expand

Link Prediction based on Structural Properties of Online Social Networks
TLDR
An improved method for predicting links based on weighted proximity measures of social networks, based on an assumption that proximities between nodes can be estimated better by using both graph proximity measures and the weights of existing links in a social network. Expand
Extracting Users' Interests from Web Log Data

  • 18 December 2006
TLDR
A method for extracting subgraphs representing users' main interests from a site-keyword graph which is generated from augmented Web audience measurement data (Web log data) and shows that it succeeds in finding sub graphs which contain most of the sites that users are interested in. Expand
