Text mining is the process to discover knowledge (or information, patterns) from text data, which are unstructured or semi-structured, by kinds of transformation of a text.
Researchers use text mining tasks such as:
Basic text analysis
Advanced text analysis (From Underwood, T. (2012). Where to start with text mining.)
Datasets are the basis for getting started a text mining project. Some textual data application programming interfaces (APIs) / platforms are openly accessible to the public and some of them are available to the HKU community.
Government and institution data
Open data for research
