Intro

To showcase cross-collection search, we need to do some co-referencing BM/Yale&Getty.

  • Manual co-referencing work will be done by BM/YCBA students/interns. Onto to load and check
  • Yale already does coreference to VIAF/ULAN.
  • Choose a dozen or so constituents that would be good for demonstration purposes, and manually add to BM data URIs for VIAF, ULAN, etc
  • Vlado: It makes sense to match not just people, but some other terms as well: places, object types, subjects... Whatever it'd be interesting to demo cross-collection search with.
  • Emmanuelle made a list of terms to be coreferenced (see next section)

Coreference Data

Vladimir put the coreferencing data to a Google sheet. Ask one of the editors (Vladimir, Dominic, Lec, Emmannuelle) for access.

It has the following columns:

  • term name
  • main thesaurus used by Yale (ULAN, TGN or AAT)
  • respective thesaurus used by BM
  • BM term matched, if different from the first column
  • additional vocabularies (eg VIAF, LCNAF for Actors). TODO these are not needed if Yale uses consistently one thesaurus.
    Note: VIAF incorporates ULAN (has more records) though it has fewer details per record
  • extra details used for disambiguation (eg life years)

Tasks

Tasks as of 4 Sep 2013:

  • Yale should ensure the IDs in col B are actually used in the RDF export, else coref won't happen
  • we're still missing some BM codes in col D (esp in Objects and Subjects). Barry or Dominic, could you add this?
  • Jana, can you task one of the devs to generate coref statements? I'm pretty sure I've seen a JS library for access to Google Docs

E.g. the first line should be:

<http://vocab.getty.edu/ulan/500026846> owl:sameAs <http://collection.britishmuseum.org/id/person-institution/23457>. # John Constable

sameAs (RKD example)

From the above sheet we'll generate the required coreference statements. We created such statements by hand for RKD (1 artist and some major cities):

How to search for BM terms

  1. Go to http://test.researchspace.org:8081/sparql (ask the same people for crendentials)
  2. Enter a query like this one 
    select * {?s rdfs:label "Giovanni Battista Borra"}
  3. Examine the results: first by scheme (URL prefix), and if needed click through to details (eg from person-institution/n to person-institution/n/birth to person-institution/n/birth/date to see the year of birth)
  4. Copy the identifier (only) to the "BM" column
  5. If the term is not the same as in the first column, record in column "BM match"

It takes some imagination to find some of the terms, eg:

  • None of the 3 place matches for "London" is the one we're looking for. You need to enter "London England" to find it (but since we've done coreferencing to RKD data, we had that one previosly)
  • even case matters. Eg "Hadleigh castle" doesn't find it, you need to type "Hadleigh Castle"

It's a pity that currently you need to use such crude techniques, but this UI (Forest) is only intended for developers.
In the future we should put the same autocomplete index that is used for RS search onto the Forest search at http://test.researchspace.org:8081/.

Explore narrower terms

The AAT Object 300041338 "intaglio print" corresponds to BM object x8049 "nature print". How did I find this guy, if it has no altLabel mentioning "intaglio"?

  • first found BM x12179 "intaglio print; intaglio, intaglio-print, nature print": but this is a Technique not Object.
    Learned why it's called "nature print": "class of printmaking using metal plates inked so as to print from the incisions (lines or dots) rather than the surface". I guess the ink naturally goes into the incisions rather than the surface.
  • then found the broader BM object term x8577 "print"
  • then explored its narrower terms with this query: 
    select ?s ?pref (group_concat(?al; separator=", ") as ?alt) {
  ?s skos:broaderTransitive <http://collection.britishmuseum.org/id/thesauri/x8577>;
    skos:prefLabel ?pref; skos:altLabel ?al
} group by ?s ?pref
  • And there you have it, in the middle of 31 objects, right between "merchant's mark" and "new year-print" is our guy: "nature print"
