Social Bookmarking and Web Search

17 05 2007

Are social bookmarking site better at Search than Google?  Do sites like del.icio.us , digg, reddit provide better search result?

I have tried some searches on 50 Matches, a search engine that crawls only sites linked on digg, reddit, or del.icio.us. 50 Matches returns only the top 50 results in each search (hence the name). The result is discouraging.

While for some specific technical terms the result from 50 matches are good, searching for general topics is not good at all.

There are probably two problems: query engine and the the specificity of sources. Today the tags information can be useful to tune the actual result from search engines and probably as vertical search in the tag engine community.

But if you don’t expect to have in the first place the official web site for your search term, but you want to know what’s going on for a certain subject, social bookmarking is maybe better.

I suppose it would a good idea to build vertical search collecting data from specific social bookmarking or try to build a “social google”.  But how incentivate billions of people to save and tag websites?

Tagging

11 05 2007

One of the most relevant aspect of the web 2.0 approach is the participation of people to create and classify information. Tags linked to hyperlinks, maps, photos, objects, video and people are the real revolution of web 2.0. They totally changes the transfer and classification of knowledge.

Information that today compose knowledge are chosen and transferred (with some piece of paper) by recognized experts of the related matter.

Now a totally new taxonomy made by tags linked to information by the community (known ad folksonomy) could change the way we find information and also which information are transferred through time.

When we tag links on del.icio.us , images on Flickr, objects in MyThings, places in MyMaps (and a lot of other places) and share this information with other users, we are building the tomorrow knowledge. Think about it when save a tag.

Recently we can also tag people and share this information on Spock. Globally sharing this information could lead to a level of transparency never reached.

Even better if we consider that from the chaos of tagging a new order is coming.
