The goal of the task is to detect and analyze the event contents in real world Chinese news texts. It consists of finding key verbs or verb phrases to describe these events in the Chinese sentences after word segmentation and part-of-speech tagging, selecting suitable situation descriptions for them, and anchoring different situation arguments with suitable syntactic chunks in the sentence. Three main sub-tasks are as follows: (1) Target verb WSD; (2) Sentence SRL; (3) Event detection.
