Promoter Account Detection in Twitter
Twitter is an online social network and micro-blog that becomes an alternative media for sharing and getting information. In the political area, Twitter provides various features as a media to promote campaign and get a good imaging for political party or contestant. In order to get a good opinion from other users, the contestant can manipulate their success with a massive promotion. This promotion activity could lead to public opinion that is not consistent with the facts. So that, we need to determine whether this is promoter account or not. In this paper, we propose a new framework for promoter account detection. This framework based on twitter content to detect promoter account according to their existence in topic of promotion. This framework employs k-means approach in order to cluster topic of promotion based on twitter\u27s content. From each cluster, we evaluate the existence of promoter account. With very simple approach, the results obtained on experiment show that this framework is effective for promoter account detection
Enhancing Twitter Data Analysis with Simple Semantic Filtering: Example in Tracking Influenza-Like Illnesses
Systems that exploit publicly available user generated content such as
Twitter messages have been successful in tracking seasonal influenza. We
developed a novel filtering method for Influenza-Like-Illnesses (ILI)-related
messages using 587 million messages from Twitter micro-blogs. We first filtered
messages based on syndrome keywords from the BioCaster Ontology, an extant
knowledge model of laymen's terms. We then filtered the messages according to
semantic features such as negation, hashtags, emoticons, humor and geography.
The data covered 36 weeks for the US 2009 influenza season from 30th August
2009 to 8th May 2010. Results showed that our system achieved the highest
Pearson correlation coefficient of 98.46% (p-value<2.2e-16), an improvement of
3.98% over the previous state-of-the-art method. The results indicate that
simple NLP-based enhancements to existing approaches to mine Twitter data can
increase the value of this inexpensive resource.Comment: 10 pages, 5 figures, IEEE HISB 2012 conference, Sept 27-28, 2012, La
