Trust and Reputation

Long ago (1998! An eternity on the scale of the web), my friend Pierre-Marie Martin wrote a text on the relevance of information on the Internet (in french).
I just read it again, and I once again measure its quality and timeliness.

At that time, there was not even Google, which has successfully exploited the relationship between relevance and the links in a page. The relevance of A is reinforced by the relevance of all the pages that have a link to A.
All pages linked to A contribute to create the referent of trust that Pierre-Marie was referring to.

In 1998, there was not yet the phenomenon of communities. An interesting aspect of the community is the freedom to participate to discussions. Or the freedom of non-participating.
The fact that we can choose to read a blog or not is, I think, the key to the confidence that we can give to its author. All the readers, free of their opinions and views, form this new form of trust referent.

That's what eBay does with its evaluation system. Sellers and buyers grade each other, and the result is a trust referent.
I personally find this system too simple to generate a real confidence. Just make an agreement with a friend (I would not say an accomplice) to improve your score.

Because trust is not a summable concept. As the Google PageRank, trust is built in a network.
Stephane Krieger has defined in his doctoral thesis an interesting concept: ~ ~ the partial transitivity of trust ~ ~.
I always partially trust someone. This someone partially trust another person. And after a few steps, it has no value. If A trusts B trusts C, which trusts D, it is very likely that A will only moderately trust D.

On the Internet, it is necessary to create confidence in the communities that would be based on such a network of partial trust. Only then we will be able to enrich, filter, classify and value the contents of communities.
We are developing the tools to create this network. Contact for more information.
