| Abstract(in English) | System logs are important for network operation. However, automatic log analysis is difficult because the logs are large scale and free format text that dependes on each device. Existing analysis results are not always useful in terms of network operation due to lack of semantic information of logs. In this work, we try to extract semantics of logs by topic modeling, which is a typical method in natural language processing. Through the examples of log time series labeling based on extracted semantics, we expect our method will bridge the gap between numerical analysis results and operational usefulness in log analysis. |
