Abstract:
The National Science & Technology Information Service (NTIS) provides knowledge map services with an integrated information of national R&D information and science & technology information. In order to solve the request of the users in real time, this paper presents a real-time knowledge map service that retrieves and aggregates the needed data and creates the map services on the fly. To select and aggregate the needed information on the fly, we used the slice and dice method, which is one of the most widely used methods in data warehousing and on-line analytical processing (OLAP) approach. In addition, we show some examples of knowledge map services, which analyze and visualize the status and the topic-trend of the national R&D information based on the real-time data selection and aggregation.
