Acquiring Activities of People Engaged in Certain Occupations

摘要

We present a system to acquire knowledge on the activities of people engaged in certain occupations. While most of the previous studies acquire phrases related to the occupation, our system acquires pairs of a verb and one of its arguments, which we call activities. Our system acquires activities from sentences written by people engaged in the target occupations as well as from sentences whose subjects are the target occupations. Through experiments, we show that the activities collected from each resource have different characteristics and the system based on the two resources would perform robustly for various occupations.
