Abstract

Big Data on Internet contains information valuable for enterprise decision making, but also challenges their traditional customized information service mode. Keyword-based search supplies as a complementary mechanism to discover the required information from Big Data, while its passive service mode and low precision brings down the efficiency of decision making. To solve the problem, a method is proposed by keeping aware of the decision making context, dynamically recognizing information requirement, automatically activating search process, based on domain knowledge previously built reflecting the latent relations between decision task types and the information required. From user view, decision making is not intercepted, and information focused on his current decision task is actively discovered, sent and displayed as support, so as to improve the efficiency.
