We examine the viability of building large polarity lexicons semi-automatically from the web. We begin by describing a graph propa- gation framework inspired by previous work on constructing polarity lexicons from lexi- cal graphs (Kim and Hovy, 2004; Hu and Liu, 2004; Esuli and Sabastiani, 2009; Blair- Goldensohn et al., 2008; Rao and Ravichan- dran, 2009).
