Re: Hierarchical Facets?
: creating a generic facet framework. It would be interesting to know if : any work has been published which enumerates the design patterns : involved. I found Marti Hearst's research paper "Design Recommendations : for Hierarchical Faceted Search" very useful... : http://flamenco.berkeley.edu/papers/faceted-workshop06.pdf You know ... i keep hearing about flamenco, one of these days i should really take it for test drive and see what's under the hood. Thanks for hte link to the paper ... I'm much of an academic, so I tend to forget that there are people out there doing hardcore research into these things. : month etc. That would require the query server to further split the : counts depending on how it was to be presented in the user interface. yeah ... for non trivial collections, the seperation between UI and functionality is a lot blurrier when dealing with facets because computing *everything* the UI *might* wnat to expose can be prohibitive. : Sure, sites like epicurious.com with their fixed number of simple facets : can be catered for in Solr. Future sites, based on thousands of facets, : some hierarchical, some Tag-like and some numerical would struggle I think! I don't know about that ... CNET has hundreds of thousands of products, with tens of thousands facet constraints ... and Solr seems to be doing ok for us :) -Hoss
Re: Hierarchical Facets?
I don't know about that ... CNET has hundreds of thousands of products, with tens of thousands facet constraints ... and Solr seems to be doing ok for us :) Touché... I'm impressed :-) Still... I've got to write an application that will allow users to assign a detailed subject classification to documents. I've just received a copy of the Bliss Bibliographic Classification. Like Flamenco, this scheme is also often mentioned in academic papers a lot because it is an instance of faceted classification rather like Ranganathan's colon classification scheme. I've been meaning to read it for a while to see what all the fuss is about... should keep me quiet for a while. - David
Re: Hierarchical Facets?
: You know ... i keep hearing about flamenco, one of these days i should : really take it for test drive and see what's under the hood. i still haven't looked under the hood, but i did puruse the owners manual... http://flamenco.berkeley.edu/data.html ...flamenco requires that all of your facets and all of your data be imported at teh same time. and while it's not neccessary for you to specify that an documents mpas to each level of a hierarchyical facet term (ie: you can say this doc maps to "Boston" you don't have to say it maps to "US>MA>Boston") you do have to specify that Boston is a child of MA which is a child of US when loading the data -- it doesn't look like there is anyway to redefine the hierarchy on the fly, so it ammounts to the same amount of precomputed information as the approach Yonik described earlier. >From what I can tell in the online Demos, Flamenco also doesn't seem to attempt anything special regarding weighting differnet depths of the hierarchy based on the current set of results -- for each hierarchical facet, the nodes at the highest level that have matches are displayed. (NOTE: i'm not sure if that's a limitation of the system, or an attempt at making the UI consistent) ... ths is the area where i think hierarchical facets are particulararly tricky, programaticly guess what the most usefull subset of the hierarchy to display would be based on the constraints the user has already applied. >From what I can tell: functionality could be added to Solr to do everything Flamenco does right now and still support updates -- all that's really needed is something to maintain the Facet configurations (order of fields, pretty lables, and Hierarchy of terms) in memory. Hell, if someone was so inclined, they could write a "flamenco importer" to parse the .tsv files Flamenco currently uses. -Hoss

: I hope someone could give it a try to reproduce what I have seen. so that we : can proove it's not a problem for all. FYI: I've had the "java -jar start.jar" Jetty instance running on my box for over 48 hours now ... no problem loading the Admin page. I'll check it again on monday. -Hoss
Re: Admin page went down
cool, I actually hope it's just my boxes. let me know. -Hui On 11/3/06, Chris Hostetter <[EMAIL PROTECTED]> wrote: : I hope someone could give it a try to reproduce what I have seen. so that we : can proove it's not a problem for all.
