• Slot-based semantic knowledge graph is built as • Word-based lexical knowledge graph is built as With two knowledge graphs, we build the edges between slots and slot-fillers to integrate them as shown in Figure 3.
the combined graph can be formulated as and E ws correspond to slot-to-slot relations, wordto-word relations, and word-to-slot relations respectively (Chen and Metze, 2012; Chen and Metze, 2013).
