A web platform for collecting text annotation and experiment data online.
LMEDS was originally developed for conducting Rapid Prosody Transcription annotations over the internet. Since then it has been extended for doing a number of different types of perceptual experiments (memory tasks, AXB-type tasks, etc.).
Ver 2.5.3 (May 29, 2019)
- Bugfix for boundary and prominence sequences not rendering properly.
Ver 2.5.2 (Feb 23, 2019)
- Critical bugfix for Python 3. Cgi was not executing properly.
- Test support for Python 2.6 was removed.
Ver 2.5 (Jun 29, 2017)
- 'Javascript refactor' (no new features) - the Javascript code used to be generated by the Python code. It has mostly been pulled out and placed into .js files that are linked to in the html header.
Ver 2.4 (Nov 02, 2016)
stimulus presentation can now be automatically randomized for each user
- post-processing scripts unscramble the individual output orders while marking the order users did the task in
task timeout and media-less support (i.e. reading tasks) added to media_choice pages
limits can be set on the minimum and maximum number of prominences and boundaries that can be made on a text in prominence- and boundary- marking- pages.
keyboard keys can be bound to buttons on a page (e.g. the 'p' button can be used to play audio or 'enter' can be pressed to submit a response)
numerous bugfixes and code cleanup
Ver 2.3 (May 17, 2016)
- Video now supported with the same controls and functionality as audio
- User scripts utilities can now be run from a web browser for great ease of use
- Sliding scales are now a supported widget
- New syllable-marking page (branch of prominence-marking pages)
- Experiment participants can now relogin and resume from where they left off
- Integration tests added for greater reliability. Also, numerous bugfixes.
Ver 2.2 (Dec 15, 2015)
- Added support for python 3.x (tested on 3.5)
Ver 2.1 (Sep 18, 2015)
- Replaced the many AXB page classes with one flexible audio_choice class
Ver 2.0 (Aug 12, 2015)
- First public release.
- Inclusion of user script utilities.
- Numerous bugfixes and stability improvements (audio is significantly less error prone).
- Offline server for running experiments locally.
- Companion website.
Ver 1.5 (May 19, 2014)
- Object oriented refactor
- Numerous bugfix and stability improvements.
Ver 1.0 (December 04, 2013)
- First stable release
Python 2.7.* or above
Python 3.3.* or above

LMEDS needs to be installed on a server and probably needs to be done by someone with a technical background. Once installed, experiments can be built with no programming experience. Please see the document LMEDS_manual.pdf for instructions on installation and use.
Please see the manual for instructions on installing LMEDS on a server, running LMEDS on a local computer (no server required), or for using the included user scripts.
