The other is knowing how we got to where we are – what is the heritage of ideas and practice on which we may draw. Vickery, B. C. (2004). A long search for information (Occasional Papers, No. 213). Graduate School of Library and Information Science, University of Illinois at Urbana Champaign. Footer 3 Three groups: Library Research Circle (India) 1951 Classification Research Group (UK) 1952 Classification Research Study Group (North America) 1959 As far as general libraries are concerned, classificatory research in the USA has taken a less spectacular form (than in Great Britain). Yet it is interesting to note that a [USA] Classification Research Group was set up … in 1959; possibly there will be a slow recognition of the value and techniques of facet and phase analysis.” Sayers, W.C.B.

Rosenfeld and Morville’s (2002) Information Architecture for the World Wide Web. Facet analysis in section 5.3.4 of the ANSI/NISO Z39.19-(2005) Guide to the Construction Management and Format of Controlled Vocabularies. NCSU Endeca / faceted browsing and navigation Flamenco - Marti Hearst Footer 9 “Low-hanging fruit”? Hearst (2008) “facets refer to categories used to characterize information items in a collection.” Reamy (2009) “facets are often derived by analysis of the text of an item using entity extraction techniques or from pre-existing fields in the database such as author, descriptor, language, and format. This approach permits existing web-pages, product descriptions or articles to have this extra metadata extracted and presented as a navigation facet” Footer 10 Strengths of facet analysis Theory drawn from practice Foregrounding domain interests information seeking strategies tasks domain vocabulary Footer 11 General site “facets” in use (2008 La Barre) Library [10] Reference [9] Museum [8] Business [3] Shopping [3] Society [3] Topic/ subject Location Author Date/year Country/region Content When Category Brand Price Title Genre Keyword Who Format Language Type 12 Michèle Hudon, Université de Montréal Virtual library of education resources Literature review (information seeking needs) FACETS: Agent (who?), Activity or process (what?), Method or tool (how?), Space or context (where?), Time (when?), and foundations (general documents) Classification of resources DDC/ Educator’s Reference Desk Assign descriptors ÉDUthès : Thésaurus de l’éducation.

(Broughton, 2001, p. 67; Mills, 2004, p. 268). (1)one characteristic of division is applied at a time [conceptual analysis] (2) division steps should be logical and proximate (3)division should be exhaustive (Mills, 2004, pp. 551). Footer 25 Planes of work Idea: The work of FA takes place in the Idea plane, where an entity is analyzed into component parts Verbal: FA continues here as further sorting and transformation of the selected categories/facets or terms occur. Notational: work of FC -- translating selected terms into notation. 26 Facet Analysis (FA) Faceted classification (FC) FA - (analytical technique) • Listing of characteristics of the entities in a universe (exhaustive, mutually exclusive) FC - (synthetic structure) • Division of entities in a universe (by one characteristic at a time) FC – (structure of synthesis) • Synthesis – combine relevant facets: Schedule of terms for description Assignment of notation 27 Background FA/FC Universal Decimal Classification • Otlet, La Fontaine -Documentalists • 1904-1907 – scheme published Bliss Bibiliographic Classification • Henry Evelyn Bliss • 1908 (practice) 1923-1933 (theory) Colon Classification • S. R. Ranganathan, • 1933 (practice) 1937-1967 (theory) (La Barre, 2000, 2003) 28 More FA / steps Identify domain / entities Mapping the scope • (Context) Examine the domain • (Content) Survey the literature • (Users) Who? Information needs? Label/ sort • Begin analysis with a list of “standard categories” (provisional guide) PMEST/ Who/ Where/ How/ What/ When • Result: set of homogeneous mutually exclusive groups (facets) • Formulate every distinctive logical category and possible relation Cluster /order • In-depth analysis of categories • Cluster terms/ objects into arrays or groups which share a common characteristic 29 Average number of facets Reference (5) Business (18) Shopping (20) Society (7) Library (6) Search Browse (1) 9 (12) 3.5 (13) 3.5 (5) 3 (6) 10 (5) 1.6 (7) 4.4 (10) 3.4 (2) 3 (6) 5.8 30 Facets in use topic/subject 28 category 21 form(at) 19 location 17 brand 13 language 11 author 10 price 10 type 9 country/region 7 title class number date/year genre library content keyword what who 7 6 6 6 6 5 4 4 4 31 Footer 32 Footer 33 Footer 34 35 36 37
