Although, the growing number of Internet users who can
play a prominent role in building collaborative groupware
systems, the ability to find helpers (tutors or other learners)
is still a challenging and important problem. Helpers
could have a lot of useful information about courses to be
taught, however, many learners fail to understand their presentations.
We suggest a new filtering framework, called a
pyramid collaborative filtering model, to trickle the number
of helpers down to just one. The proposed pyramid has four
levels. Moving from one level to another depends on three
filtering techniques: domain model filtering; user model
filtering; and credibility model filtering. Our experiments
show that this method greatly improves filtering effectiveness.
