With the development of information technology in recent years, log analysis has gradually become a hot research topic. However, manual log analysis requires specialized knowledge and is a time-consuming task. Therefore, more and more researchers are searching for ways to automate log analysis. In this project, we explore methods for train log analysis using natural language processing and unsupervised machine learning. Multiple language models are used in this project to extract word embeddings, one of which is the traditional language model TF-IDF, and the other three are the very popular transformer-based model, BERT, and its variants, the DistilBERT and the RoBERTa. In addition, we also compare two unsupervised clustering algorithms, th...
