Data mining is the process of using computational methods to retrieve and analyse large sets of data for the purposes of identifying patterns, trends and relationships.
Text mining, also referred to as text analysis, is a kind of data mining that uses computational methods to search for, extract and analyse text data. The purpose of text mining is to identify patterns, trends, or connections in textual material. Text and data mining (TDM) are often referred to together.
Use this guide to find resources and tools for TDM. See the Data visualisation guide for information about visually presenting your data.
Watch How does Text Mining Work? (YouTube video) to see how text mining can be used in research.

There is no specific exception in the Copyright Act for text or data mining. Copying or reformatting material without permission may therefore infringe copyright. See Australian Government: Text and data mining for more information on current law.
Licencing conditions specific to data and text mining vary from publisher to publisher. Downloading or scraping large amounts of data from a database may be prohibited. Ensure you understand any issues around copyright and licencing conditions for the content you wish to use before proceeding.
Ensure you have considered any ethical issues that might arise from your use of the content, particularly when working with sensitive information. The Association of Internet Researchers has established Ethical Guidelines for Internet Research to assist researchers to make ethical decisions. You can also refer to our Ethics and consent page for more information.
Text and data mining may involve working with and storing large data sets. To help ensure your data is stored securely, refer to the Research data management toolkit.
Text and data mining may involve the extraction and analysis of text or data from a range of sources including licenced library databases, open-source data, and researcher generated data.
