Trust/Reputation in Search
I've been wondering whether reputation can be conveyed in any other way in search algorithms than Google's PageLink algorithm (which seems to me to be a measure of popularity - albeit in a network sense - rather than of reputation). I was reading an article in the ASIST Journal called "When Documents Deceive" by Clifford A. Lynch on the bus home, and came across the phrase:
"The question of formalizing and recording expectations...[of] trust in behavior [is] very poorly explored. There are a number of avanues: certification or rating services that might be consulted, or webs of individuals vouching for behaviour of others"I'd been pondering whether it might be possible (particularly in an intranet) to modify a search engine so that when a user rates a page, he or she can also see in his/her search results how people like him/herself have rated the pages and/or how people he or she trusts rated the pages. This might seem a bit daft, but I was wondering whether, a bit like FOAF, a search engine could have a "who do you trust?" section, where you log-in, and then identify other people on a database whose opinion you trust. Search results might gain extra weighting within the overall results based on their "reputation" rating 9where the results would be specific to your trust network). I suppose the problem is placing the burden on users of registering and keeping their "trust networks" up to date, and the fact that it would become a very large database, but that detail could be ironed out by brains greater than my own.
