How did we prepare the i.Experience mirror?
We recently updated the Greenfield site in preparation for:
- An internal OEIT project to replace the video players in selected courses with SpokenMedia project player.
- An internal OEIT project to demonstrate search through SpokenMedia transcript files for delivery via MIT’s Google Search Appliance integrated with Greenfield OCW courses.
- A joint project with MIT OpenCourseWare to test OER Recommender/Folksemantic.com recommendations with select OCW courses.
Here are the steps we used to prepare the i.Experience mirror of MIT OCW. This is our first second implementation of i.Experience.
Notes:
- I originally started writing this post in April, but I’ve updated it to include the most recent changes to the mirror site.
- I expect to produce a new version of this guide in mid-/late-August as OCW issues a new version of their mirror.
Dev Note: Google SA custom search
Summary
MIT’s OCW implementation uses MIT’s Google Search Appliance to support searching the OCW site. This Development Note discusses customizing this search mechanism to provide richer, more useful results.
Background
MIT’s OCW site contains static content. Unlike dynamic web sites where content can be assembled into a page on demand, each page at http://ocw.mit.edu exists fully formed waiting to be served. While this approach has advantages, it limits the ability of users to query specific results. The reason is that Google is simply looking for words; it doesn’t attribute any semantic meaning to these words. For the query “Marx”, Google depends on the user submitting the query to distinguish between Groucho and Karl.
Objective
Use of MIT’s Google Search Appliance yields multiple benefits. The primary benefit is that it leverages the current solution to return a richer query result set. MIT’s OCW has very high standards for stability, scalability, and conventionality. A solution that used its current solution would make it more attractive for future adoption. Another benefit is the power of the Google search algorithms. After all, “Google” is synonymous with online searching.

Integrating the SpokenMedia Player
We’ve put together an initial demonstration of how we might change the user experience for OCW videos
(There are still some CSS issues to work through. And we only converted over the first two minutes of the transcript file.)
And here’s the original.
i.Experience
i.Experience is OEIT’s first forary into a new, “Interactive Experience” for OpenCourseWare and Open Educational Resources.
We worked with MIT OCW to install a local mirror copy of OCW and have already modified it slightly (within the license and terms of use).
In the next few weeks we will do things such as:
- Incorporate the SpokenMedia Player into the video pages.
- Integrate the MITOEIT Recommender system (based on Folksemantic.com/OER Recommender technology)
- And…who knows, the sky’s the limit!
Welcome!
Welcome to Project Greenfield!
The MIT Office of Educational Innovation and Technology has launched Project Greenfield as an experiment to enable MIT faculty to explore how OpenCourseWare and Open Educational Resources might be used in new and innovative ways.
We’re just getting started, and we invite you to join us on this journey.
