Predictions based on Twitter — A critical view on the research process

摘要: Twitter data is increasingly used to make predictions about real-world events. However recently, several studies directly or indirectly questioned proposed prediction procedures. In this paper, we conduct a literature review investigate the research processes adopted by previous in detail. We first identify actors involved, and then study how they influence different phases of process. found that up four perform sampling, filtering, classification assessment decisions throughout development models. If these reasons behind them are not sufficiently documented, developed methods cannot be reproduced future consequently their validity reliability hard assess.
