In this chapter, we focus on the multimedia service data preprocessing and feature extraction, which are core steps in the multimedia QoE evaluation. Specifically, multimedia service data collection and preprocessing is firstly introduced. We briefly describe three representative datasets: (1) IPTV service dataset collected by operator; (2) OTT service dataset collected from students in Nanjing University of Posts and Telecommunications; (3) dataset crawled across the web. Then, we highlight our works about feature extractions for user-related IFs, containing five aspects: viewing time ratio calculation, user interest inference, user type classification, user behavior analysis, and user emotion parsing from their comments in danmaku.
