Taxonomy in Lucene
Hi
I want to include Taxonomy feature in my search.
Does Lucene support Taxonomy? How?
If not, is there in different way to add Taxonomy feature in the Lucene
search?

Dipak

The Lucene in Action book provides an example solution for indexing
synonyms using WordNet.
They core of the approach is - to my understanding - to add to equip
synonym Tokens with the very same positions as the "original" Tokens and
add them to the TokenStream.

Hello Dipak,
I'm interested by an answer here if you find one.
The way we have solved this in intergeo (or... are about to) is to use
query expansion, we explain that in:
http://www.activemath.org/~paul/pubs/cross-curriculum-search.html
more hints welcome.

Re: Taxonomy in Lucene
Posted by "Karsten F." <ka...@fiz-technik.de>.
Hi John,
I intended to compare xtf with hierarchical facet browsing in browseengine
(selection expansion).
I found PathFacetCountCollector/PathFacetHandler#getFacetsForPath, and I
think that the implementation in xtf has a lot of advantages.
So I suggest you to reuse the xtf-source for that (GroupCounts.addDoc in
package org.cdlib.xtf.textEngine.facet).
Best regads

Re: Taxonomy in Lucene
Posted by John Wang <jo...@gmail.com>.
wiki:http://bobo-browse.wiki.sourceforge.net/
this describes the upcoming 2.0 release, which is in the ill-named
branch: BR_DEV_1_5_0
We are still doing some development work on that, feel free to check out the
branch and we will be doing a release shortly.
some features we aimed for 2.0 and also reasons for the api changes:
1) support for selection expansion: The ability to select a value in a
field, and allow the sibling facets to come back, e.g. intersect with other
fields and keep the current field not intersect with selected value. This is
rather tricky to be fast, e.g. doing 2 searches.
2) allow the framework, ability to handle derived data, e.g. build facets
from data not necc. on index. Some examples, in linkedin's case, being able
to facet on different distances of the social graph, etc.
3) Being able to handle multi valued facets, e.g. 1 docid -> into multiple
values.
4) being able to do 1) on range facets.
etc..

Hi John,
I will take a look in the bobo-browse source code at week end.
Do you now the xtf implementation of faceted browsing:
starting point is
org.cdlib.xtf.textEngine.facet.GroupCounts#addDoc
?
(It works with millions of facet values on millions of hits)
What is the starting point in browseengine?
How is the connection between solr and browseengine ?
Thanks for mention browseengine. I really like the car demo!

We are doing lotsa internal changes for performance. Also upgrading the api
to support for features. So my suggestion is to wait for 2.0. (should
release this this month, at the latest mid jan) We can take this offline if
you want to have a deeper discussion on browse engine.

hi glen,
possible you will find this thread interesting:
http://groups.google.com/group/xtf-user/browse_thread/thread/beb62f5ff9a16a3a/16044d1009511cda
was about a taxonomy like in your example.
Also take a look to the faceted browsing on date in
http://www.marktwainproject.org/xtf/search?category=letters;style=mtp;facet-written=
In solr 1.3 the faceted browsing was implemented with filter for each
possible value.
The implementation in xtf is quite more sophisticated (
http://xtf.wiki.sourceforge.net/programming_Faceted_Browsing ).
I am not familiar with current version of solr.

: >From what I understand:

not inherently, that's just one of the most common mental models. The
common approaches for dealing iwth faceted search in Lucene all work
equally well when dealing with a taxonomy as long as your faceting code is
*aware* of hte taxonomy and only computes the facet counts it needs to
based on the users "current" location in the taxonomy (unless of course
you want ll the counts for hte entire taxonomy in all cases -- in which
case no pecial logic is needed: only your presentation layer needs to care
about the taxonomy)
the simple faceting support provided out of the box by solr can easily be
used for taxonomy based faceting if you encode your taxonomy breadcrumbs
in the docs (a google search for "solr hierarchical facets" will give you
lots off discussion on this).

A taxonomy in general has an arbitrary depth:
Example: Biological taxonomy:
Kingdom Animalia
Phylum Acanthocephala
Class Archiacanthocephala
Phylum Annelida
Kingdom Fungi
Phylum Ascomycota
Class Ascomycetes
Order Acarosporales
Family Acarosporaceae
Genus Acarospora
Acarospora admissa

Hi Dipak,
Which kind of "Taxonomy"?
Where is the difference to "faceted browsing" in your case?
