Microsoft's Marc Smith is leading the charge in the hunt for the Holy Grail of social
computing. I'm not a total convert to his brand of social reductionism,
but I have to admit that he has some really compelling ideas (and
toys!
). If you ever get a chance to
hear Marc speak, don't pass it up.
CNET: So could all of this
ultimately add up to a better search engine? Marc Smith: If things
go well, we'll have a better search engine. This remains early, initial
research, but our results look promising. Reranking results based on social
histories does do a better job, and I do believe we will deliver interfaces that
will find people who are debators, fine, but also those who are answer
people...It turns out that people have a lot to give each other. There's a lot
of knowledge to share, and 2 percent of every population is motivated to be a
knowledge sharer. Most of us have to rely on signs or symbols that suggest a
person is reliable. With doctors you have their diplomas, the way the office
looks, and most important, who referred you--these are all indicators that we
rely on. We are trying to create analogous tools for online environments where
that data is latent, is not manifest in the interfaces
visibly. ... CNET:
Tell me about the AURA (Advanced User Resource Annotation)
project. Smith: AURA is about
extending NetScan: "What if you could use NetScan with a pocket computer and
attach threads to things?" We use the Toshiba e740 and a Compact Flash bar-code
reader, run AURA software, and can walk up to any bar-coded object, any
ISBN-coded object, scan it, and the device brings back information about that
object…We imagine being able to walk up and down the aisle of a grocery store
and have a handheld computer rate everything with a green light, a red light, a
skull and crossbones.
In Hong Kong, during the height of
the SARS outbreak, there was a system that could tell you which buildings had
had confirmed SARS cases. Now that's a reputation system.
...
[series of questions about analysis of newsgroup
postings]
Smith: ...
frequency distribution of thread properties is very illuminating .... But
how do you know [newsgroup
posters] have value? It's not just the number of days you come back.
There are three other metrics, which tend to be ratios. One is the ratio of
replies: How many times did you reply to someone else, or start a thread?
Spammers may show up every day, but they don't reply. With a very low
reply-to-post ratio, I would say that that is a person who starts a lot of
conversations but never replies to anyone else, and it's probably a spammer.
Showing up every day is not enough--you have to respond to other people. It's
also thread-to-post. How many threads did you touch, how many messages did you
write? If you wrote 10 times, all into one thread, that's a low ratio. You have
a high conversational concentration. ... high reply-to-post indicates a
flame warrior, because they tell you you're an idiot and they put all their
messages into a few threads--so they also have a low thread-to-post
ratio.
...
CNET: When you talk about a reputation system,
I'm reminded of the eBay system. Smith: We're similar but different--eBay is an
explicit feedback system, and we are an implicit feedback system. With eBay,
buyers rate sellers, and sellers rate buyers, after they conduct a transaction.
It's what people say about you. But there are real problems with this--most of
all inflation, the "Beverly Hills-adjacent" problem. If you read the L.A. real
estate section, everything is "Beverly Hills-adjacent." So there is this
tendency to inflate. There have been empirical studies of reputation ratings at
eBay that suggest that just going by reputation ratings at eBay is not an
indication that you're not going to get a fraudulent
transaction.
