| Abstract(in English) | Recently, a new generation of mining algorithms is necessary for real-time analysis and query response in data stream applications: for example, outlier detection from sensor network data, prediction of stock price data, web access analysis from click stream data and so on. In this paper, we propose methods for automatic trend detection over time-series data streams to discover useful knowledge. We validate the accuracy and affectivity of our methods by analyzing stock price data and news articles. According to the resultant classifiers which disclose the correlation between stock data and news articles, we can predict rise/drop trend of stock price when given a newly released news article. |
