A faceted bROwSEr by any other name…

Saturday, August 25th, 2007

When doing research for my thesis, I’ve found that there’s an incredible amount of terms being used to describe the user interface paradigm known variously as faceted browsing, view-based search or several other names.

Some of the better known applications using this paradigm (or user interface design pattern, if you prefer) are Flamenco, Epicurious, Wine.com, and of course MuseumFinland which was made in our group.

Here’s a list of the terms I found, together with comments, just in case someone finds it useful.

I’ve ordered the terms based on the number of hits they give on Google, most popular first.

This should give an idea of the relative popularity of each.

Faceted search (165000 hits)
Somewhat misleading, since searching brings in mind text search. Nevertheless this seems to be an accepted general term for the paradigm.

Guided navigation (133000 hits)
A product by , often used to refer to the paradigm it implements. Also used, somewhat surprisingly, in the 3rd edition of the Polar Bear book (I would have preferred a more vendor-neutral term). The number of Google hits is surprisingly large. It is possible that the term (or just the two adjacent words) is used in some other context, although most hits I checked did seem to refer to Endeca or the paradigm.

Faceted browsing (81300 hits)
Used by the SIMILE project (e.g. Longwell, Exhibit). Also appears in Wikipedia in the form Faceted browser. I like the implication that this is just a special kind of browsing.

Faceted navigation (44800 hits)
Used in Welie’s design pattern collection and a spot is reserved in the Yahoo! design pattern collection as well, although the description is not yet there.

Faceted metadata (24500 hits)
Used by the Flamenco project. The problem with this term is that in some cases, the original metadata is not faceted and has to be restructured into facets first. Of course, what you get then is even more metadata. This term also doesn’t sound like a user interface thingie, it sounds like low-level technical stuff.

Dynamic taxonomies (800 hits)
Used by Giovanni M. Sacco in his papers, not many others.

Relational navigation (768 hits)
A term for their Seamark product. As far as I can tell this is just the same paradigm with a new name, but maybe they’ve added something to it.

View-based search (490 hits)
This was used by the HIBROWSE project, one of the first (if not the first?) user interfaces based on this paradigm. However, nowadays the term is only used by our research group. I think the term has something to do with the HIBROWSE interface having lots of small windows or views to the data, but no separate list of search results that would stand out – thus, all you had to work with were the views. More recent systems generally dedicate only a small amount of space to the facets/views and lots of space for the results.

Multi-facet search (327 hits)
Yet another name, used in some papers from our research group.

I am not aware of any significant differences in the meaning of these terms. AFAICT any application where one of the terms is appropriate could be described using any other. There are obviously some differences in emphasis of different aspects but the core meaning seems to be the same.

My personal recommendation would be to consider using either faceted browsing, faceted navigation or faceted search, in that order, when referring to the paradigm. The other terms are problematic, marginal and/or vendor-specific. Also, in all of these recommended terms, the connection to faceted classification (used in the library sciences) is fairly obvious.

Edit Aug 29: Added “multi-facet search”, which I forgot from the first round.

RDF – Hit’n’run in Doom style

Thursday, November 23rd, 2006

Does RDF resources and properties make you sick? No problem, you can now shoot them in a Doom style game called RDFRoom created by our Semantic Web collegues in Germany. The game is cool and makes semantic web researching even more fun than before!
Osma noticed also, that it is especially fun to shoot concepts in our soon-to-be-published General Finnish Ontology YSO. This might be the killer application of both the semantic web and ontologies! :)

(Thanks to Osma for finding the game and creating the patch to the game to support RDF with scandinavian characters.)

Inside Semantic Computing

Sunday, November 19th, 2006

Welcome to the blog of the Semantic Computing Research Group SeCo!

This blog has been launched as a more relaxed publishing channel for SeCo people and their views on semantic computing (e.g., semantic web), computing in general, life inside SeCo etc. This is also our experiment in using web 2.0 tools (such as blogs and wikis) as a part of our work.
We hope you enjoy reading the SeCo blog! Please don’t hesitate to give feedback!

Regards,
Kim

konvergointi – mitä se on?

Tuesday, October 24th, 2006

Olet kenties pohtinut mitä konvergointi on? Tässä näkemyksiä:

“Konvergointi tarkoittaa sitä, että hampaistosta, puremalihaksista ja muista kasvojen alueen kudoksista lähtevät
hermosäikeet yhtyvät samoihin keskushermoston ratoihin.” (http://www.tietoviikko.fi/doc.te?f_id=622235)

Toisaalta Tampereen teknillisestä yliopistosta varoitetaan, että “Konvergointi suuren mittakaavan diskreetissä
optimointitehtävässä on kuitenkin epävarmaa, koska vastaavien tehtävien ratkaisemisesta ohjelmalla ei ole tietoa.”
(http://www.tut.fi/units/me/tme/diplomityo/norja/nastran_optimization.htm)

Nimim. DowNtimE on puolestaan havainnut, että “Konvergointi onnistuu kyllä ihan hyvin mutta käynnistyksessä punainen
väri häiritsevän paljon “väärässä” verrattuna siniseen.” (http://www.dvdplaza.fi/forums/showthread.php?t=34420)

Hieman pelottavalta tuntuu se, että “Konvergenssillä tarkoitetaan silmien kykyä kääntyä sisäänpäin.”
(http://www.stadia.fi/opiskelu/sote/optometria/aineistot/naontutkimus/KLP.asp)

Eero Hyvönen puolestaan toteaa, että “konvergointi tarkoittaa entropian vähenemistä mentaalisessa avaruudessa”.

Ja eikun konvergoimaan! :)
