Corpora are an important tool for linguistic research. Regular expressions, as a key text-matching tool, can provide precise corpus search functions. With the help of text editors that support regular expressions, they can also assist in organizing corpora, helping to build text corpora. At the same time, regular expressions can support corpus annotation. This lecture first introduces the basic concepts, principles, and matching rules of regular expressions, and then, using EmEditor as an example, demonstrates their applications in corpus searching, construction, and annotation, providing useful corpus tools for beginners.
