FEAST - A Multistep, Feedback Centric, Freshness Oriented Search Engine

This work aims at a multi-step feedback centric Web search engine ensuring the retrieval of relevant fresh live results instead of those existing in the indexes. The methodology is based on the new concept called "micro search" which in turn creates the "micro indexes". These micro-indexes are the key factors utilized in re-ranking the selected documents. A prototype of the system called FEAST (freshness enriched active searching technology) has been implemented. The results of experiments conducted on FEAST are encouraging and they confirm the improved quality of information retrieved.
