    1. 1. “ Seek, and ye shall find:” Using Controlled Vocabularies to Enhance Access to Cultural Information SLA Seattle June 16, 2008
    2. 2. Controlled Vocabularies: an Overview Murtha Baca Head, Vocabulary Program Getty Research Institute SLA Seattle June 2008
    3. 3. TYPOLOGY of DATA STANDARDS <ul><li>Data structure standards (metadata element sets): </li></ul><ul><ul><li>MARC, EAD, Dublin Core, CDWA, VRA Core </li></ul></ul><ul><li>Data content standards (cataloging rules): </li></ul><ul><ul><li>AACR (  RDA), ISBD, CCO, DA:CS </li></ul></ul><ul><li>Data value standards (vocabularies): </li></ul><ul><ul><li>LCSH, LCNAF, TGM, AAT, ULAN , TGN, MeSH </li></ul></ul><ul><li>Data format standards (standards expressed in machine-readable form): </li></ul><ul><ul><li>MARC, MARCXML, EAD, CDWA Lite XML, Dublin Core Simple XML schema, DC Qualified XML schema, VRA Core XML schema </li></ul></ul>
    4. 4. What are vocabularies? <ul><li>Maps to guide people to information </li></ul><ul><ul><li>creating / filling </li></ul></ul><ul><ul><li>searching / researching </li></ul></ul><ul><ul><li>organizing / classifying / thinking </li></ul></ul><ul><li>Collections of terminology where relationships between terms are represented </li></ul><ul><li>Data value standards (i.e. what is used to “fill” metadata elements/categories or “containers” of information) </li></ul>
    5. 5. “ Knowledge bases” -- bodies of knowledge represented by language (glossaries, dictionaries, thesauri, word lists) What are vocabularies?
    6. 6. Types of terms in vocabularies <ul><li>personal names: Collate, Charles B. </li></ul><ul><li>geographic names: Campbeltown (Argyll and Bute, Scotland, UK) </li></ul><ul><li>object names: clack valve </li></ul><ul><li>corporate names: Cambrian Railways </li></ul><ul><li>iconographic subjects and themes: The Legend of John Henry </li></ul><ul><li>genre terms: political cartoons, fish stories </li></ul><ul><li>multilingual equivalents: flat car (English) = Schienenwagen (German) = platforma (atklata) (Latvian) </li></ul>
    7. 7. What is a controlled vocabulary? <ul><li>A tool for consistency in the language used in the recording and retrieval of information </li></ul>
    8. 8. What is a controlled vocabulary? <ul><li>An organized arrangement of words and phrases that are used to index content and/or to retrieve content through navigation or a search </li></ul><ul><li>Typically a vocabulary that includes preferred terms and has a limited scope or describes a specific domain </li></ul>
    9. 9. Types of Controlled Vocabularies
    10. 10. Controlled Lists <ul><li>Simple lists of terms used to control terminology </li></ul><ul><li>In a well-constructed controlled list: </li></ul><ul><ul><li>Each term must be unique (no homographs). </li></ul></ul><ul><ul><li>Terms should all be members of the same class. </li></ul></ul><ul><ul><li>Terms should not be overlapping in meaning </li></ul></ul><ul><ul><li>Terms should be equal in granularity or specificity. </li></ul></ul><ul><ul><li>Terms are arranged alphabetically or in another logical order. </li></ul></ul>
    11. 11. Controlled Lists cont. <ul><li>May include terms from other controlled vocabulary resources (especially standard published vocabularies) </li></ul><ul><li>For some elements or fields in a database, a controlled list may be sufficient to control terminology, particularly where the terminology for that field is limited and unlikely to have synonyms or ancillary information. (Example: artists’ roles in ULAN, place types in TGN). </li></ul>
    12. 12. <ul><li>Controlled list: A simple list of terms used to control terminology </li></ul>manuscripts miscellaneous paintings photographs sculpture site Installation texts vessels Example of a controlled pick list for Classification Patricia Harpring, 2008 © J. Paul Getty Trust
    13. 13. <ul><li>A list comprising sets of terms that are considered equivalent </li></ul><ul><li>No preferred term </li></ul><ul><li>Generally used for search and retrieval, providing access to content that is represented in natural, uncontrolled language </li></ul>Felis domesticus Synonym ring list Jean-Baptiste Perroneau, Portrait of Magdaleine Pinceloup, © J.

    14. 14. Compilations, usually in alphabetical order, that combine separate concepts into a “string,” as in the Library of Congress Subject Headings (LCSH) Commercial fishing -- Japanese competition Salmon fisheries -- law and legislation -- California Subject Headings
    15. 15. Pre-coordination of terminology is a characteristic of subject headings; subject headings typically combine several unique concepts together. Subject Headings cont. Subject headings--Pictures. Pictures--Computer network resources. World Wide Web--Subject access.
    16. 16. Taxonomies/Classifications Vocabularies that organize a body of knowledge for a defined domain into conceptual categories, e.g. Nomenclature for Museum Cataloging , ICONCLASS. The Greek heroic legends Story of Hercules (Heracles) Labors of Hercules Hercules chokes the Nemean lion Hercules kills the Hydra of Lerna Hercules captures the Ceryneian hind Hercules captures the Cretan bull http://www.iconclass.nl/
    17. 17. Compilations of terms representing single concepts . Thesauri explicitly express relationships among terms via a semantic structure. <visual works by form> dioramas diptychs medals medallions (medals) polyptychs triptychs Thesauri
    18. 18. Authority Files <ul><li>Compilations of authorized terms or headings used by a single information system, organization, or consortium for cataloging, indexing, and documentation. </li></ul><ul><li>Main purpose is to regulate usage . </li></ul><ul><li>Include synonyms (“ See” references) and related or associated terms (“ See also” references). </li></ul><ul><li>Examples include Library of Congress Name Authority File (LCNAF), local authorities for names, subjects, etc. </li></ul><ul><li>Authority files may take the form of thesauri, word lists, etc.—in other words, any kind of vocabulary can be used as an authority. </li></ul>
    19. 19. More on Thesauri
    20. 20. Thesauri <ul><li>Terms in a thesaurus may have the following three types of relationships: </li></ul><ul><ul><li>Equivalence </li></ul></ul><ul><ul><li>Hierarchical </li></ul></ul><ul><ul><li>Associative </li></ul></ul>
    21. 21. Thesaural Relationships <ul><li>Equivalence </li></ul><ul><ul><li>synonyms, spelling variations, language variations </li></ul></ul><ul><li>Hierarchical </li></ul><ul><ul><li>broader to narrower </li></ul></ul><ul><ul><ul><li>whole/part </li></ul></ul></ul><ul><ul><ul><li>genus/species </li></ul></ul></ul><ul><li>Associative </li></ul><ul><ul><li>related concepts </li></ul></ul>
    22. 22. Equivalence Relationship : Terms/names denote the same thing—a preferred name is used for displays <ul><li>Bulgarini, Bartolomeo </li></ul><ul><li>(Sienese painter, circa 1337-1378) </li></ul><ul><li>Lorenzetti, Ugolino </li></ul><ul><li>Master of the Ovile Madonna </li></ul><ul><li>Ovile Master </li></ul>example from ULAN
    23. 23. Equivalence Relationship <ul><li>still lifes </li></ul><ul><li>still life </li></ul><ul><li>still-lifes </li></ul><ul><li>still lives </li></ul><ul><li>nature morte </li></ul><ul><li>natura morta </li></ul><ul><li>stilleven </li></ul><ul><li>Stilleben </li></ul><ul><li>vie coye </li></ul><ul><li>ontbijtje </li></ul><ul><li>banketje </li></ul>
    24. 24. Whole/Part Relationship : “children” or narrower terms are part of the parent or broader term <ul><li>España..........................(nation) </li></ul><ul><li>Andalucía.......................(region) </li></ul><ul><li>Almería.........................(province) </li></ul><ul><li>Cádiz...........................(province) </li></ul><ul><li>Córdoba.........................(province) </li></ul><ul><li>Granada.........................(province) </li></ul><ul><li>Huelva..........................(province) </li></ul><ul><li>Málaga..........................(province) </li></ul><ul><li>Sevilla.........................(province) </li></ul>
    25. 25. Genus/Species Relationship : “children” represent types of the “parent” or broader term <ul><li>funerary sculpture </li></ul><ul><li>brasses </li></ul><ul><li>effigies </li></ul><ul><li>gisants... </li></ul><ul><li>haniwa </li></ul><ul><li>tomb slabs </li></ul><ul><li>ushabti </li></ul>
    26. 26. Associative Relationship : terms are related conceptually, but not necessarily hierarchically <ul><li>Descriptor: charterhouses </li></ul><ul><li>Hierarchy: Built Complexes and Districts </li></ul><ul><li>Scope note - Carthusian monasteries. </li></ul><ul><li>Alternate Forms of Speech {ALT}: </li></ul><ul><li>charterhouse </li></ul><ul><li>Synonyms and spelling variants {UF}: </li></ul><ul><li>certose </li></ul><ul><li>charter houses </li></ul><ul><li>chartreuses </li></ul><ul><li>Related concepts: </li></ul><ul><li>Carthusian (Religions hierarchy) </li></ul>
    27. 27. indexer thesaurus: A thesaurus designed to control terminology and guide indexers in the choice of terms. See also end-user thesaurus . indexing: Also called human indexing . The process of evaluating information and designating indexing terms by using controlled vocabulary that will aid in finding and accessing the cultural work record. Refers to indexing done by human labor, not to the automatic parsing of data into a database index , which is used by a system to speed up search and retrieval. indexer thesaurus
    28. 28. A thesaurus designed for direct access by searchers rather than for use by indexers. Instead of controlling the terminology, the purpose of an end-user thesaurus is to help searchers find useful terminology for improving, narrowing, and broadening their queries. end-user thesaurus
    29. 29. A vocabulary constructed with the goal of being interoperable with an existing vocabulary, e.g. a specialty vocabulary such as a conservation thesaurus that is intended to be linked to the superstructure of a larger vocabulary, such as the AAT. satellite vocabulary
    30. 30. Vocabularies provide <ul><li>intellectual “paths” that can improve access to information </li></ul><ul><li>Harlem Renaissance </li></ul><ul><li>Negro Renaissance </li></ul><ul><li>New Negro Movement </li></ul><ul><li>Renaissance, Harlem </li></ul><ul><li>Renaissance, Negro </li></ul>Jacob Lawrence Tombstones , 1942 Example from the AAT
    31. 31. Why do we need vocabularies? <ul><li>Because of national and regional differences: lorries vs. trucks , lifts vs. elevators, Tom Thumb golf courses vs. miniature golf courses </li></ul><ul><li>Because of historical vs. contemporary names: Iran vs. Persia vs. Islamic Republic of Iran </li></ul><ul><li>Because of political and social changes: KhoiKhoi vs. Hottentot </li></ul><ul><li>Because of linguistic differences: Titian vs. Tiziano vs. Titien ; pottery vs. keramik vs. céramique </li></ul><ul><li>To disambiguate homographs: sinopia (pigment -- Materials hierarchy) vs. sinopia (preliminary drawing -- Visual Works hierarchy) </li></ul>
    32. 32. Why do we need vocabularies? <ul><li>Thesaural relationships provide greater research/searching capabilities: </li></ul><ul><li>drawings </li></ul><ul><li><drawings by function> </li></ul><ul><li>preliminary drawings </li></ul><ul><li>underdrawings </li></ul><ul><li>sinopie </li></ul>
    33. 33. Issues in vocabulary-enhanced searching <ul><li>User interfaces are problematic </li></ul><ul><li>Optimally, controlled vocabularies should be used both on the “back end” and on the “front end” to be most effective </li></ul><ul><li>Economics: consistent implementation of controlled vocabularies is time- and labor-intensive </li></ul><ul><li>Vocabulary control is almost non-existent on the Web at present </li></ul>
    34. 34. Search “ARES” Against Getty Web site
    35. 35. “ ARES” did not match any pages
    36. 36. Improve recall by ORing equivalent names (Ares, Mars)
    37. 37. “ Ares OR Mars” now retrieves 37 pages
    38. 38. Search “ARES” Against Google (returns 1,250,000 pages; none of first 6 pages are relevant)
    39. 39. Increase precision by ANDing the broader/parent term of ARES, “Major Gods”
    40. 40. “ Ares AND Major Gods” now narrow to 506 hits (all first 7 pages are relevant)
    41. 41. Recall and Precision <ul><li>Note that when searching “Ares” against the Getty site, it retrieves nothing. So we need to include synonyms/equivalents (OR “Mars”) to improve recall. When performing the same search against Google, however, it returns too many hits. So we need to combine the broader term (AND “Major Gods”) to improve precision. This illustrates how important it is for a retrieval system to be flexible and let the user decide how to refine the search according to specific situations. </li></ul>

    46. 46. notes Gaudí was influenced by Catalonia's medieval history and architecture. His works display a respect for craftsmanship and structural logic. He was also inspired by forms in nature, using it in structure and ornament, creating a highly personal, organic style. His work is characterized by sculptural plasticity, the manipulation of light, and the use of mosaics and polychromy. His later style is classified as Catalan Modernisme, a style related to Art Nouveau. roles architect, landscape architect, furniture designer geographic location Reus (Spain) Barcelona (Spain) nationalities Catalan, Spanish bibliography Contemporary Architects (1987) Enciclopedia universal ilustrada (1978-1983) Encyclopedia of world art (1959-1987) Grove Dictionary of Art online (1999-) LC Name Authority Headings [online] (2002-) Elements of a ULAN record related people studied with: Juan Martorell Montells life dates Birth Date: 1852 Death Date: 1926 names Gaudí, Antoni Gaudí y Cornet, Antonio Cornet, Antoni Gauí Gaudí i Cornet, Antoni artist 500014514
