Search Engine - Supervised Rankings

Was going through various online journals on search engines when i stumbled upon this document published by mondosoft. Its interesting as they have argued the importance of human intervention in search engines. I wish i could attach the entire pdf here, but you may be able to download it from here
This document mainly covers points about gathering user behaviour data, interpreting and analyzing log data, providing informative results etc. Its worth a read. I am trying to get more whitepapers from them.
We have also concluded on similar findings. Our bottleneck lies in implementation. Don't even think that we are technically incapable. Its just that sometimes too much discussions amongst bright people results in a very stringent priority list. The best approach could be to have a clear plan for 6 months and work towards it. Its however easily said than done. For us, market feedback and faster turnaround time in crucial. We are always on our toes.
I am planning to write a small journal on search engine implementation soon....
