(English Abstract)
In this paper, we address the filtering problem of data stream data. In general, stream data are continuously generated, and the volume are very large. Therefore, in order to process such a large-capacity data stream in real time, a filtering algorithm should be used to sufficiently remove unnecessary data for analysis. However, since existing filtering algorithms are optimized for a single data type, it is difficult to precisely filter different data types with only one filtering algorithm. To solve this problem, in this paper we propose an Esper-based real-time filtering system that applies various filtering algorithms to Esper, a typical data stream management system (DSMS). The proposed system is designed and implemented based on the client-server model. First, the client transmits the user¡¯s input for filtering to the server and displays the filtering results received from the server in real time. The server filters the data stream in real-time according to the user input and returns the results to the client in real time. Experimental results on real data stream show that the proposed system filters data stream accurately and quickly. In addition, because it supports various filtering algorithms, we can easily filter various types of streams and compare the results. As a result, the proposed filtering system is considered to be an excellent system for extracting data more accurately and efficiently by selectively supporting a filtering algorithm suitable for the type of input data streams.
