| Abstract(in English) | Data stream is becoming increasingly important in several domains such as finance, sensor network environment, manufacture, network monitoring. The most fundamental support needed in these applications is efficient monitoring of time series data streams, and a subsequece-matching mechanism is required. In this paper, we propose a new function to recognize the similarity between subsequences, and then present an efficient sequence matching algorithm for data streams. Several experiments with synthetic and real data sets show that our algorithm works well as expected ; it can efficiently detect sequence trends in the data sets. |
