Text Analytics in Social Media [chapter]

Xia Hu, Huan Liu
2012 Mining Text Data  
The rapid growth of online social media in the form of collaborativelycreated content presents new opportunities and challenges to both producers and consumers of information.  ...  In this chapter, we first introduce the background of traditional text analytics and the distinct aspects of textual data in social media.  ...  For example, tag "Japan Earthquake" does not contain any words or phrases related to "Nuclear Crisis" while we learn that these two events are related from recent news.  ...

Ranking Documents Based on the Semantic Relations Using Analytical Hierarchy Process

Ali I., Hesham A., Rabab S.
2016 International Journal of Advanced Computer Science and Applications  
In this work, we present a method for utilizing genealogical information from ontology to find the suitable hierarchical concepts for query extension, and ranking web pages based on semantic relations  ...  So, it provides an accurate solution for ranking documents when compared to the three common methods.  ...  The second method is a ranking process for documents based on the semantic relation between document contents and the query terms. II.  ...

A Consolidated System for Robust Multi-Document Entity Risk Extraction and Taxonomy Augmentation [article]

Berk Ekmekci, Eleanor Hagerman, Blake Howald
2019 arXiv   pre-print
As the taxonomy expands, the amount of relevant information increases and multi-sentence extractions become more preferred, but this is tempered against entity-risk relations become more indirect.  ...  We introduce a hybrid human-automated system that provides scalable entity-risk relation extractions across large data sets.  ...  Acknowledgments Thank you to anonymous reviewers from NAACL Industry Track as well as Matt Machado, Nathan Maynes, and Scott McFadden for support and feedback.  ...

Visual Exploration of Spatial and Temporal Variations of Tweet Topic Popularity [article]

Jie Li, Siming Chen, Gennady Andrienko, Natalia Andrienko
2018 Eurographics Conference on Visualization  
Our approach includes an analytical pipeline and a multi-view visualization tool.  ...  As attempts of topic extraction from very short texts like tweets may not produce meaningful results, we aggregate the texts prior to applying topic modelling techniques.  ...  There are about 6900 different hashtags; we created for each hashtag 78 documents (78 weeks) for topic extraction.  ...
