Facets + Tags
Posted by David Weinberger
Siderean has always allowed their customers to embed hierarchical trees within their faceted classification system (example here) when appropriate. E.g., if someone is navigating via the geography category, the system can know that SoHo is in NYC which is in NY state which is in the US. And Siderean has shown an early curiosity about tags: Its fac.etio.us thought-experiment/demo turns del.icio.us bookmarks into a faceted system.
I got briefed by the company a couple of days ago and learned that future releases of their navigation software are going to incorporate tagging more directly, enabling users to annotate/tag the data they find. A faceted system might add a right amount of organization to a pile of tags, making that pile far more useful. Imagine a folksonomic faceted system…

David... multifaceted systems are nothing more than clusters of static "views" (from ideologically defined starting points)... views that make "visible" just sections from an always larger semiotic space.
The "tagging" ala del.ici.us, on the other hand, is like a open ended, real time, ongoing tropological exploration/"mapping" of the semiotic space. It is - at the same time - a process of discovery and creation (densification and enlargement) of this space.
Faceted systems are like documented "archaeologies" of past tropological practices like the "tagging".
Which means that, of course, you can easily "generate" faceted "views" from "tagging" data. The question would always be - who defines the starting "points of view"... and from what "point of view"... :)
To take your example about SoHo... how would the system know that I care about its geography. SoHo lives in a myriad of other dimensions. Geography is just one of them.

First, just to be clear: Faceted systems from places like Siderean and Endeca are real-time in that the paths are not pre-computed. They are dealing with information spaces that are too large to make that practical. But, as you say, the facets are designed ahead of time. That's why the intersection of tagging and FC is interesting.
Yes, SoHo as a facet can be known to live within the geography hierarchy, but SoHo as a tag can be in an indefinite number of dimensions (i.e., may I tagged it "Soho" because it reminds me of a cat of that name). Again, that's why I find the intersection of these two approaches interesting.

The software is simply great. Great service and very simple to use. Thank you for a very well written article.

That seems a good idea, especially for separating tags related to content of the bookmark from tags related to the bookmark itself (genre, attribute ...). Indeed, I think a separation should be made between tagging content, and "meta-tagging".
Yet, what's behind this, and how points of view are defined: Do you know if there's any kind of ontology to represent the spaces, and if there's some linguistic tools that can guess on which facet new terms belong (eg: tagging with a company name that have not been in the database before)

I found Siderean implementation very interesting and clever. Another innovative application from Bradley Allen and his team in facetede search market.
