ECIR 2014: Proceedings of the 36th European Conference on IR Research on Advances in Information Retrieval - Volume 8416（2014）
Abstract
In this work we analyze the discussions on Twitter around the Human papillomavirus HPV vaccinations. We collect a dataset consisting of tweets related to the HPV vaccinations by searching for relevant keywords, by retrieving the conversations on Twitter, and by retrieving tweets from our user group mentioning semi-relevant keywords. We find that by tracking the conversations on Twitter relevant tweets can be found with reasonable precision. Although sentiments and opinions change regularly in a discussion, we find few cases of topic drift.
