A graph-theoretic approach to extract storylines from search results

Ravi Kumar, Uma Mahadevan, D. Sivakumar
2004 Proceedings of the 2004 ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '04  
The core algorithmic task involved is to mine for signature structures in a robust graph representation of the search results. We present a very fast algorithm for this task based on local search.  ...  Our framework is axiomatically developed and combinatorial in nature, based on generalizations of the maximum induced matching problem on bipartite graphs.  ...  Our proposal to use signature structures as the one outlined above may be viewed as an application of ideas from link analysis-specifically the work of Kumar et al.  ...

DISTL: Distributed In-Memory Spatio-Temporal Event-based Storyline Categorization Platform in Social Media

Manu Shukla, Ray Dos Santos, Andrew Fong, Chang-Tien Lu
2016 Proceedings of the 2nd International Conference on Geographical Information Systems Theory, Applications and Management  
In this paper, we present DISTL, an event processing platform which takes as input a set of storylines (a sequence of entities and their relationships) and processes them as follows: (1) uses different  ...  Event analysis in social media is challenging due to endless amount of information generated daily.  ...  Rules Application As each of these rules are applied to a storyline for each event, if any rule is satisfied for a storyline against an event, the storyline is categorized under that event.  ...

SVEN: Informative Visual Representation of Complex Dynamic Structure [article]

Dustin L. Arendt, Leslie M. Blaha
2014 arXiv   pre-print
However, both of these classical techniques have significant drawbacks, so a new approach, Storyline Visualization of Events on a Network (SVEN) is proposed.  ...  SVEN encodes time in a natural manner, along the horizontal axis, and optimizes the vertical placement of storylines to decrease clutter (line crossings, straightness, and bends) in the drawing.  ...  Acknowledgements The authors would like to thank Paul Havig at AFRL for his guidance and helpful comments throughout the project.  ...

Chen Lin, Chun Lin, Jingxuan Li, Dingding Wang, Yang Chen, Tao Li
2012 Proceedings of the 21st ACM international conference on Information and knowledge management - CIKM '12  
Given a query of an ongoing event, we propose to sketch the real-time storyline of the event by a two-level solution.  ...  Comprehensive experiments on Twitter data sets demonstrate the effectiveness of the proposed methods in each level and the overall framework.  ...  We refer this problem as Generating Event Storyline from Microblogs (GESM). For example, Figure 1 presents the storyline based on an event query of "Egypt Revolution".  ...
