summarySupervised methods provide the best performances for Information Extraction (IE), but require labeled data that is costly to create. We introduce a new IE task, Semantic Context Path (SCP) tagging, that extracts richer information than simple named entity recognition, while allowing for easier creation of training data than for relation extraction. In this presentation, we (1) define the SCP tagging task, (2) describe an efficient method to create training data for the task, and (3) design and evaluate baselines extraction models for SCP tagging on English and Korean. These models are integrated into a dedicated map interface allowing semantic navigation through user' comments.
