Thesaurus Hierarchy - limit the number of broader terms precoordinated

Thesaurus Hierarchy - limit the number of broader terms precoordinated

When the Thesaurus Precoordinate registry entry is set to "True" the entire hierarchy is entered as a prefix to the chosen term.   

"For example, if chosen term C has a broader term B which has a broader term A, this Setting will result in the following text being displayed when C is chosen: A-B-C."

Whilst it is useful to know where in the hierarchy a specific term belongs - I don't want to see ALL the broader terms. It would be better to specify exactly how many broader terms are precoordinated.

For example; if using term F, we might want to see its broader term E (but don't want to see A, B, C or D).

Currently the Precoordinate entry adds very cumbersome terms (especially in Getty Hierarchies). For example - selecting the term "Public art" in AAT adds the value:

"Top of the AAT Hierarchies | Associated Concepts Facet | Associated Concepts | concepts in the arts | genres in the arts | art genres | Public art"

It would be useful to be able to specify the number of levels in the hierarchy that are precoordinated - and this might need to vary depending on the thesaurus.    For example: For APT thesaurus I may want to precoordinate 1 term, but for AAT, 3 might be required.

Has anyone discovered a way to solve this already, or developed a custom solution for this with KE?

Would anyone else find a more specific registry entry useful?

Many Thanks,

Rowena

Re: Thesaurus Hierarchy - limit the number of broader terms precoordinated

Hi Rowena,

You might be interested to know that KE has made some progress on revisions to the Thesaurus Module, in case you are not yet aware. I recall that you provided feedback on the "Thesaurus Enhancements in EMu" thread in this forum. Some of these developments were presented at the User Group meeting, at University of Pennsylvania, in 2015. I wonder if these changes might provide a better solution than setting a limit on the number of full term organizations to be displayed.

A new left pane is available in the Thesaurus Module, based on Archives View, that shows a hierarchical/tree display of every BT-NT organization for each term. A new Hierarchy tab can be added that displays a tree view of a term's full organization. That tab includes every distinct organization for a term (BT/NT, not Alternate or Use/Used For). Both are fairly new, and have only briefly been "in the wild" for live feedback. What I have seen so far, however, looks rather promising. In the current version, the loading of these views can be a bit sluggish, especially for terms with a large number of organizations. It is still a significant improvement, however, on the previous Browse View.

My main KE/Axiell contacts related to the Thesaurus enhancements have been Ian and Brad. If you are unable to obtains details about the recent Thesaurus Module changes/developments, or if I may be of any assistance, otherwise, please let me know. 

Best,

Will

Thanks for the leads, Will

If the presenter of the Thesaurus Paper from the North American User group is out there... and is willing to post it here / or PM me their paper that would be wonderful! (The papers are not published on this site yet )

Thanks,

We are preparing to implement the changes in our next upgrade, so would love to hear from those who are currently using it.

Thanks,

Re: Thesaurus Hierarchy - limit the number of broader terms precoordinated

Hi Rowena,

At the National Gallery of Australia we have been recently working with KE Software on the final developments for the IRN based thesaurus module for EMu 5.0.  This has the browse panel on the left hand side of the Thesaurus module in Query, Insert and Display, as well as a dynamic heirarchy tab - these are fantastic inclusions for module usability.

As an IRN based Thesaurus what displays in linked/referenced fields is generally set by the SummaryData (in our case anyway) and as such my understanding of the precoordinate setting may no longer apply, as the inherent structure has changed. 

The IRN based thesaurus is used in my understanding by a number of EMu clients in Australia and New Zealand and KE Software could provide them with the details for you.  In my knowledge we are one of the most recent clients (in Australia) to move to an IRN based thesaurus and are the primary testing site for EMu 5.0, as such I would be happy to answer any questions about that is of any help about the newer module.

There was also a presentation at the KE Software conference in Adelaide this year by Luca about the developments in EMu 5.0 including the IRN based thesaurus and I also presented on our use of the IRN based thesaurus at the NGA.

With EMu 5.0 (that we are currently testing) we are excited to say that we are working with the combination of UTF-8 encoding and the new IRN based Thesaurus module, which is a great combination especially if you are currently using the Getty Thesauri (AAT or TGN) as the Getty has moved to Unicode character sets.

Sadly I am not able to be any assistance with the EMu standard (non-IRN based) thesaurus however, your EMu client manager should be able to provide you with some contacts for those using it, if you don't get any feedback from the forum.

Warmest Regards,
Renee
