Text mining

What is text mining?

  • Identifies new search terms that you may not have considered, based on an existing set of key papers relevant to your topic
  • Software "mines" (analyses) the records and pulls out subject headings, text phrases and other data that helps you extend your search strategy to find new records

When is it useful?

  • Systematic reviews or extensive literature reviews where it is important you don't miss anything
  • Not necessary for standard literature searches

About text mining tools: Yale MeSH Analyzer

The Yale MeSH Analyzer creates a spreadsheet from a set of known articles, clearly setting out fields such as title, abstract, MeSH headings and author assigned keywords. Spreadsheets can be exported in an Excel format and they are easy to scan for search terms that you may never have thought of. These can then be used to search for new articles.

At the top are standard citations, but if you keep scrolling it will take you to a lovely MeSH Cloud where you can easily see the main subject headings used in those records. It looks something like this cloud from a different topic:
