Replication Package for “Robust and Efficient Log Anomaly Detection: A Hybrid ID-Semantic Approach for Evolving Systems”

This dataset contains the replication package for the article “Robust and Efficient Log Anomaly Detection: A Hybrid ID-Semantic Approach for Evolving Systems.” It includes the extended Deeploglizer-based implementation used in the experiments, the noise-generation scripts used to create template-evolution test data, the LLM prompt used for generating evolved templates, and the processed data/files required to reproduce the reported results on the HDFS and BGL datasets. The package supports three experimental settings within a unified LSTM-based pipeline: (1) the original ID-only baseline, (2) a semantic-only SBERT baseline, and (3) the proposed hybrid ID-semantic approach with OOV semantic fallback. README files are provided to explain the folder structure, installation steps, data preparation workflow, and experiment commands.
