Creating Sentiment Corpora from Microblogging Using Machine Learning

A. Alghamdi
2015 International Journal of Sciences  
Microblogging, on the other hand, reduces the cost of creating the resources.  ...  Our proposed approach to machine learning is to use active learning which aims to make the process of resource creation more effort and time efficient.  ...  A number of approaches have been proposed for sample selection, and the one we will be using is uncertainty sampling (Lewis, 1995) , which is the most commonly used query framework (Settles, 2009 ).  ...

A transfer learning based framework of crowd-selection on twitter

Zhou Zhao, Da Yan, Wilfred Ng, Shi Gao
2013 Proceedings of the 19th ACM SIGKDD international conference on Knowledge discovery and data mining - KDD '13  
In this demo, we show our framework that tackles the problem of crowdsourced task assignment on Twitter according to the social activities of its users.  ...  The central problem is simple but tricky: given a crowdsourced task, who are the most knowledgable users to ask?  ...  Many existing works have studied the problem of crowd selection on microblogs [2, 5, 3, 9] . However, they select the workers for crowdsourced tasks based on only trustiness.  ...
