This repository contains several bits of R code to undertake text mining to look for emergent trends and "weak signals".
- Background info on "weak signals" is on my blog @ Weak Signals and Text Mining I - An Introduction to Weak Signals
- An outline of relevant text mining techniques and some ideas for using them to look for weak signals is given in a follow-on posting @ Weak Signals and Text Mining II - Text Mining Background and Application Ideas
The text that is being "mined" is drawn from conference abstracts and community blog posts. In this wiki, the general term "document" refers to either an abstract or a blog posting.
- Code: Rising and Falling Terms
- Code: History Visualiser
- Code: Abstract Acquisition Scripts
- Output and Results
Output created using "Rising and Falling Terms" is currently a report formatted as an HTML page:
- Report on 2010 season conferences (ECTEL, ICALT, CAL, ICWL)
- 2010 season conferences (ECTEL, ICALT, CAL, ICWL)
- Rising Terms
- Falling Terms
- Established Terms
- Acknowledgements
Many thanks to contributors to R core and packages. The whole lot is thrilling!
