In this event, we will welcome researchers who are active in the field of digital humanities to teach us about “regular expressions” in an easy-to-understand manner. A “regular expression” is a way to specify a pattern of characters to make search and replace convenient. For example, they are very useful when searching for a specific word in a large amount of text, or when trying to find a word in a consistent format. If you use it well, it will make your work much easier. However, it is also true that there are some tricks and unexpected pitfalls. In this workshop, we will introduce some “little tricks” for those who want to use regular expressions for the first time, or for those who want to learn them properly again. If you want to handle characters better or organize data more easily, please feel free to join us!
