Self-describing Elements

 Titles  “Authors” (i.e., persons, families, corporate

bodies associated with the resource)

 Publication information (places of publication,

publishers, dates)

 Series  Identifiers: ISBN, URLs, etc.  Etc. (extent, dimensions, etc.)

Objective data (helps with “recall” – adjusted

through relevance ranking and other algorithms of search engines)

6

slide-7
SLIDE 7

Added Descriptors (Added Value)

 Controlled vocabularies

 Authority data: name/subject terms

 Classification numbers  Other categorizations (e.g., genre/form)  “Added value” images, sound, etc.

Subjective data (helps with precision of a search)

slide-8
SLIDE 8

Multiple Perspectives

 Bibliographic data  Authority data

 Names (Persons, corporate bodies,

families, works/expressions)

 Classification numbers, Subject

terms, Genre/Form

slide-9
SLIDE 9

Name Authorities

 VIAF (Virtual International Authority File)

 Persons  Corporate bodies  Families  Places (geographic names)  Works/expressions (“uniform titles”)

 Linked to dictionaries, biographical tools,

images, and resources and other “Linked data”

  • n the Web

Subject Authorities

 Controlled vocabularies

 Basis/scope

 Same/similar: LCSH, RAMEAU, RVM  Different: LCSH vs. MeSH

 Coverage

 Concepts – Biophysics, Literature, History, Thermoreceptors  Events – War of 1812 ; Hague, Treaty of, 1717  Historical periods – Jurassic, Post-modern  Etc.

Subjects: Lessons Learned

 IFLA’s MulDiCat – Multilingual

Dictionary for Cataloguing Terms and Concepts

 LCSH/RAMEAU/RVM – linked data

experiments

 MACS (Multilingual Access to Subjects) –

LCSH/RAMEAU/GND

Mapping: Multilingual Issues

 11

 mathematicsmatematica  algebraalgebra  Feironželezorauta

 1n (one to many)

 Ambiguity: Football = Soccer? American football?

katumus = remorse,regret,repentance

vacation homes = loma-asunnot, lomakodit hiking = vaellus, retkeily

 10

 geyser, tsunami  stork

slide-18

Mapping vs. Complementing

 Linked data mapping experiments:

 LCSH/RAMEAU/RVM  MACS

 ALTERNATIVE: Complementarity of terms

in bibliographic records

slide-19
SLIDE 19

Complementarity

 Linked bibliographic records for the same

resource

 multiple controlled vocabularies/terms  multiple classification numbers  linked descriptions with natural language

notes

 Linked digital resource

 natural language from the resource itself

Different Perspectives

 Different points of view of

catalogers/indexers

 academic background of the person doing the

describing

 training in applying cataloging rules, classification

schemes, subject terminology

 Complement each other  Beneficial to add terms/numbers in

bibliographic records for the same resource to provide access to the resource

21

slide-22
SLIDE 22

Classification

 Shelf organization = one number

 But often a work is “about” many topics

 Classified catalogs – multiple class numbers

for retrieval

 To cover multiple concepts of the work

 Local budgetary decisions: Limited amount

  • f numbers/terms assigned

 International links increase subject access

22

slide-23
SLIDE 23

Benefits

 Reduce costs worldwide – share the

descriptions, share the work

 Increase access for researchers/users

 Let all the descriptors serve – multiple perspectives

 Share globally
