Facetted classification
Metadata? Thesauri? Taxonomies? Topic Maps! - Making Sense of It AllLars Garshol, Development Manager at Ontopia posted a - topic maps, ontologies, taxonomies, and more. Well worth the read, since it's a clear explanation that separates similar concepts that too often get muddled.
How to Make a Faceted Classification and Put It On the WebWilliam Denton has released a well written , created for the Faculty of Information Studies at the University of Toronto. Here's a bit about what you might expect to learn:
This paper will attempt to bridge the gap by giving procedures and advice on all the steps involved in making a faceted classification and putting it on the web. Web people will benefit by having a rigorous seven-step process to follow for creating faceted classifications, and librarians will benefit by understanding how to store such a classification on a computer and make it available on the web. The paper is meant for both webmasters and information architects who do not know a lot about library and information science, and librarians who do not know a lot about building databases and web sites. The classifications are meant for small or medium-sized sets of things, meant to go on public or private web sites, when there is a need to organize items for which no existing classification will do.
Putting Facets on the Web: An Annotated BibliographyWilliam Denton's covers the design faceted classification systems for the World Wide Web.
Keyword extraction and facet analysis for email archivesKathryn La Barre and Chris Dent have been experimenting with computational methods for creating a faceted access structure of the Unrev-II mailing list archives.
The email archive of the unrev-ii list is the basis for this ongoing project, to build an access tool for an email archive that also functions as a knowledge repository. Methods utilized in future iterations of the project will include traditional semantic analysis, clustering algorithms, and facet analysis.
They have a available, and have .

Data visualization through facetsPointed out by Steve Mulder on SIGIA: Iokio has a demo of a product selection tool that uses different facets to choose a digital camera. Sliders allow the user to adjust cost, weight, and resolution with real time feedback on available models. Thanks to Joe, who discovered a direct link to their .

BC Vickery up for grabsI Found a facsimile of Brian Campbell Vickery's
Faceted Classification Schemes . It would be truly excellent if someone could get the Vickery books (or excerpts of them) to be repro'd at a place that delivers. I just ordered a loan of this one from my corporate library.

Discussion is heating up a little and is dropping science on us. The great advantage in having PhDs and doctoral students discussing on the list is that a thorough understanding of the facet analysis and classification literature can inform practice. Already there is a great need to really define and understand what facet analysis is, what facet classification is, how they are done, etc. This is one case where I think it is necessary to be pedantic because I fear that misunderstanding of the terms may result in incompletely executed implementations that call themselves faceted classification systems. Before we start to throw these terms around liberally in meetings with decision makers, we should be sure we know what we are talking about and be able to answer the most basic as well as the more difficult questions about what facet analysis and classification is and how it will positively effect the user experience.
As someone who thought himself to have a very fundamental understanding of these concepts, the discussion of facet analysis and classification in the past year has done more to confuse these concepts than to clarify them in my opinion, and for that reason, I am glad that this new list was created. There seems to be a great desire to get the outcome of facet analysis -- the browsable faceted interface like Flamenco, but there hasn't been a lot of discussion about how the method of facet analysis takes place. The terms have not even been defined clearly enough in my opinion. I have heard them defined and discussed well in presentations, but we need the terms and the methodologies to approach facet analysis better summarized in accessible articles that can help practicing IAs.
New mailing list for faceted classificationPeter Van Dijk (Poor But Happy) and Phil Murray (Knowledge Management Connection) are starting .
All About Facets & Controlled VocabulariesKarl Fast, Fred Leise and Mike Steckel have started on Boxes and Arrows to make facetted classification and controlled vocabularies accessible to practicing IA's without LIS backgrounds. Look forward to it.
This is XFML, with a nice description of how XFML can be used to describe content from different points of view, like looking into the center of a gemstone from each of its multiple faces (facets). As with the concept of topic maps, this example illustrates how description can be done post content publishing when you use a format like XFML. This is the power of what Peter V's created, coupled with the facetmap tool. The descriptions and relationships of content can be overlayed on top of the content. Nice description and .
International Children's Digital Library: Facet browsing ZUIPeter V. pointed to the , a Java application that offers an interface for browsing an ebook catalog. What's unique about the catalog is that it offers a type of zoomable interface for browing categories such as About (Subject), Genre, Setting, Characters, etc. Clicking one facet drills you deeper into that facet tree, that is to say, reveals the sub-facets/categories and/or reveals the items within that node in a tiny thumbnail results window at top that you can expand to review hits. Each term you pick -- terms are the end-points, the buttons that don't have further sub-division -- is added to your collection (on top of the worm graphic) to show that you've combined terms in your search. You can click on one of the terms in that area to remove it from your search. The results window shows how your search terms have narrowed your results.
You have to have the Java Virtual Machine plug in installed to use this application. To start browsing by facet, click "Find books in category".
