Michelle Brook, Peter Murray-Rust, and Charles Oppenheim have published "The Social, Political and Legal Aspects of Text and Data Mining (TDM)" in D-Lib Magazine.
Here's an excerpt:
The ideas of textual or data mining (TDM) and subsequent analysis go back hundreds if not thousands of years. Originally carried out manually, textual and data analysis has long been a tool which has enabled new insights to be drawn from text corpora. However, for the potential benefits of TDM to be unlocked, a number of non-technological barriers need to be overcome. These include legal uncertainty resulting from complicated copyright, database rights and licensing, the fact that some publishers are not currently embracing the opportunities TDM offers the academic community, and a lack of awareness of TDM among many academics, alongside a skills gap.
