Contextual Information Portal Generator

The Contextual Information Portal (CIP) Generator is a focused crawler that takes a topic as its input and crawls the web for pages relevant to that topic. The pages are downloaded, and indexed for use later without a network connection. One basic use of a CIP is to serve as a bootstrapping mechanism for a web proxy cache behind a slow or intermittent connection. The CIP crawler could be used at the deployment location as a prefetcher. Alternatively, a CIP could be constructed elsewhere with a a better connection and then shipped to the deployment site using a portable storage device (e.g. flash drive, hard drives, and DVDs).

Another way to use a CIP is as an information resource for building offline applications. An example of this is to use a CIP to build an education portal. An education portal can be generated easily using a course syllabus as the input of topics. To interact with such a portal we have developed a simple bookmarking tool as a Firefox plugin to create, edit, and share lesson plans. To use the portal the teacher simply searches and browses the pages in the portal and builds a lesson plan that can be used during class by the teacher or for the students to use directly.



CIPs may also be adapted to mobile devices with some associated storage via flash storage and a web browser. Ie. on an Android phone.

Deployments

Site #1: Kalpakkam, India

Preliminary user study of CIP + RuralCafe with lesson plan bookmarking tool in Kalpakkam, India. We worked with a teacher in an after-school program to use the set of tools to evaluate ease of lesson plan construction.



Site #2: Nairobi, Kenya

I worked with Strathmore University in Nairobi to coordinate students for teaching using the CIP + RuralCafe offline web portal. I setup a pilot deployment at five peri-urban schools near Nairobi, Kenya:
