• Text Categorization as a Graph Classification Problem (2015, methodology): “This representation was first used in keyword extraction and summarization (Ohsawa et al., 1998; Mihalcea and Tarau, 2004) and more recently in ad hoc IR (Blanco and Lioma, 2012; Rousseau and Vazirgiannis, 2013).”
• Event Detection and Tracking in Social Streams (2009, methodology): “Mory et al. (Mori, Miura, & Shioya 2004; 2006) used features extracted from the KeyGraph (Ohsawa, Benson, & Yachida 1998) in which each maximally connected component, which is called a foundation or basic concept, is chosen as a document feature.”
