Information Management is
  • Identifying information needs
  • Locating information sources
  • Selecting information sources
  • Organizing information
  • Disseminating information

3
S.R. Ranganathans Five Laws
  • Books are for use
  • Every reader his book
  • Every book its reader
  • Save the time of the reader
  • A library is a growing organization
  • (From Jesse H. Shera. Libraries and the
    Organization of Information. Hamdon, CT Archon
    Books, 1965)

5
Information Context
  • Information systems have collections and
    policies. Their effectiveness is based on
  • Reliability
  • Efficiency
  • Security
  • Quality
  • Etc.
  • Response time
  • Accuracy
  • Through put
  • Relevancy
  • Economy

6
Information
  • Categories of Information
  • Are they external or internal?
  • What do contents reflect?
  • What are the available formats?
  • Are there any specific terms and conditions to
    access?
  • How are the systems regarding speed, accuracy,
    consistency, and accountability?
  • What about costs?

7
Standards
  • Internal and External Standards
  • Are there any standards?
  • Are those standards internal, external, or both?
  • Do they comply with the stated standards?
  • Who (or unit) has the responsibility in
    implementation, monitoring and evaluation of
    standards?

8
Defining Information Needs
  • Users of Information
  • Do they belong to different groups?
  • Who are they?
  • What are their information needs?
  • How would information help?

9
Bibliographical Record
  • Serves users and also information providers
  • Data elements relevant to a document
  • Controlled vocabulary
  • House-keeping aspects

10
Level of Description (1.0D)
  • Base the choice of a level of description on the
    purpose of the catalogue or catalogues for which
    the entry is constructed
  • First Level of Description (1.0D1)
  • Second Level of Description (1.0D2)
  • Third Level of Description (1.0D3)

    experimenting with computers to produce books
  • 1964 - The recording of library of congress
    bibliographical data in machine readable form
  • 1965 - LC/CLR/ARL sponsored a conference to
    determine requirements for a machine readable
    record

32
MARC (Machine Readable Cataloging)

    records for English language monographs on
    magnetic tape to 16 participating libraries
  • 1968 - The MARC pilot project. Final report on a
    project sponsored by the Council on Library
    Resources, Inc (includes description of work and
    reports of the participating libraries)

33
MARC (Machine Readable Cataloging)

    data conversion is necessary (time-consuming and
    costly)

50
OCLC, MARC, SGML and HTML
  • In descriptive (text) mark up contents of a
    document is structured not the physical format
  • Document contents (chapter, paragraph, footnote,
    bibliography) are categorized using codes for
    effective retrieval to meet different needs

51
SGML
  • Standard Generalized Mark Up Language (SGML) is
    referred to as Metalanguage
  • Developed in 1970 as GML (General Mark Up
    Language) meets national and international
    standards (ISO 8879)

52
SGML
  • Permits description of structured information
    through syntax (classes of documents) called DTDs
    (Document Type Definitions) written with specific
    applications
  • 3 projects TEI (The Text Encoding Initiative)
    BFAP (Berkeley Finding Aid Project) and DIAP
    (Columbia University Digital Image Access Project)

Four Major Classification Schemes
  • Library of Congress Classification (LCC)
  • The scheme of classification drawn up by Herbert
    Putnam in 1897. Although based in some respects
    on the Dewey Decimal Classification and Cutters
    expansive schemes, it does not conform to
    theoretical rules for classification. It was
    quite explicitly compiled to meet the needs of
    the librarys huge collection of books and is too
    detailed and complex to use in small libraries.
    It has however, been adopted by research and
    university libraries throughout the world.

87
Four Major Classification Schemes
  • Dewey Decimal Classification (DDC)
  • Devised by Melvil Dewey and first published in
    1876, since when it has been revised nineteen
    times. Knowledge is divided into the ten main
    classes, each designated by a numeral form zero
    to nine, which can be then subdivided by the
    addition of two numerals before a decimal point
    and further numerals after it. It has a relative
    index which shows the relation of each subject
    that is indexed to a larger subject (or class
    division). The published schedules have been
    extended and modified in successive editions.

(1997). International Encyclopedia of Information
and Library Science.
88
Four Major Classification Schemes
  • Universal Decimal Classification (UDC)
  • Essentially an elaborate expansion of the Decimal
    Classification of Melvil Dewey, using various
    symbols in addition to Arabic numerals to create
    long and expressive notations for particular
    documents. This makes it particularly appropriate
    for use in specialist libraries and collections,
    and its adoption by the International
    Organization for Standardization (ISO) has
    ensured its worldwide use. It was developed by
    the Insitut Internationale de Bibliographie, now
    FID, under the direction of Paul Otet and Henri
    la Fontaine.

89
Four Major Classification Schemes
  • Colon Classification (CC)
  • Designed by S.R. Ranganathan, it is based on the
    classficiation of any subject by its uses and
    relations, which are indicated by numbers divided
    by a colon . It was the first example of an
    analytical-synthetic classification, in which the
    subject field is first analyzed into facets, and
    class numbers are provided for most topics but
    are constructed combining the classes of the
    various unit schedules of which the scheme
    consists. It has proved particularly popular in
    India and has inspired classification researchers
    in many parts of the world.

  • In 1923, Sears List of Subject Headings (Sears)
    was introduced to small libraries

Subject Access to Information
  • Two Main Viewpoints
  • Natural Language VS. Controlled Vocabulary
  • Controlled Vocabulary Systems
  • Evolution
  • Alphabetic VS. Classified Arrangement
  • Current Scenario
  • Library of Congress Subject Headings
  • Sears List of Subject Headings
  • Medical Subject Headings
  • Others

Comparison of Natural and Controlled Language
Natural Language Strengths High specificity gives precision. Excels in retrieving individual terms- names of persons, organizations, etc. Exhaustively gives potential for high recall. Does not apply to title-only databases. Up-to-date. New terms immediately available. Words of author used- no misinterpretation by indexer. Natural language words used by searcher. Low input costs. Easier exchange of material between databases- language incompatibility removed. Controlled Language Weaknesses Lack of system specificity, even in detailed systems. Lack of exhaustively. Cost of indexing to level of natural language prohibitive. Also terms may be omitted in error by indexers. Not immediately up-to-date. Time lag while terms are added to the thesaurus. Words of authors liable to be misconstrued. Errors in indexing terms can cause losses. Artificial language has to be learned by the searcher. High input costs. Incompatibility a barrier to easy exchange.
Both natural and controlled language systems
offer the same powerful search aids- truncation,
word proximity, etc.

Comparison of Natural and Controlled Language
(cont.)
Natural Language Weaknesses Intellectual effort placed on searcher. Problems arise with terms having many synonyms and several species. Syntax problems. Danger of false drops through incorrect term association. Exhaustively may lead to loss of precision. Controlled Language Strengths Eases the burden of searching Controls synonyms and near-synonyms and leads to specific natural language concepts to the nearest preferred terms to broaden search Qualifies homographs Provides scope notes Displays broader, narrower and related terms Expresses concepts elusive in free text. Overcomes syntax problems with compound terms and other devices. At normal levels of indexing, avoids precision loss through over-exhaustively (i.e. retrieval of minor concepts of peripheral interest). An asset in numerical databases and multilingual systems.
Both natural and controlled language systems
offer the same powerful search aids- truncation,
word proximity, etc.

Controlled Vocabularies
  • Subject Approach
  • Point out what a library/information source or
    database has on a particular subject
  • Point out what a library/information source or
    database has on a related subjects
  • Two popular pre-coordinated subject heading lists
    in the US
  • The Library of Congress
  • Sears List of Subject Headings

Controlled Vocabularies
  • Other lists are in specific fields

    purpose of the information package (e.g., who the
    intended users are) in the following
  • Title and subtitle.
  • Table of contents or equivalent.
  • Preface and/or introduction (etc.).
  • Illustrations and their captions.
  • Identify names used as subject concepts.
  • Identify role(s) of any geographic name(s)
    present.
  • Identify chronological elements.
  • Identify form of the item being analyzed.
  • Construct a sentence giving analysis of what this
    information package is about.
  • Identify index terms from the sentence to be
    searched in the controlled vocabulary.
  • Translate the terms into specific headings from
    the controlled vocabulary list.
  • Construct the hierarchy (discipline/subdiscipline/
    concept/topic, etc.) into which the aboutness
    falls.
  • Convert the hierarchy into a classification
    notation.

Mechanization of Bibliography
  • Automation first entered in 1870s with the
    introduction of typewriters (Lot of discussion)
  • In 1890s, the documentation Movement in Europe
  • Development of Professional Organizations and
    Scientific Research
  • UDC was discussed in 1892 conference in Brussels
    (organized by Otlet and LaFontaine)
  • In 1937, the American Documentation Institute was
    formed. In 1968 changed its name to ASIS. In 2000
    became ASIS T

117
Mechanization of Bibliography
  • In 1938, FID was established
  • In 1928, Eastman Kodaks technological advance in
    microfilm
  • World War II- Information Explosion
  • In 1945, Vannevar Bush opened a new era
    (associative index)
  • In the 1950 and 1960s many mechanization
    attempts
  • Creation of MARC format at LC
  • OCLC (online college library center)
  • RLIN (research libraries network) in 1977

118
How does system design relate to the organization
or information?
  • System design holds together the metadata that
    serve as surrogates for the information package
    within a domain.
  • Before computerization, the people who created
    surrogate records were the same people who
    organized them, so system design was not a
    separate process.
  • Panizzis rules proposed the contents of
    surrogate records and also the standards for
    cataloging them.
  • Cutters rules included an emphasis on
    collocation (logical juxtaposition of records)
    and a design for the card catalog and filing.
  • Each edition of ALA filing rules has assumed that
    the system design is based on a card catalog.

119
System designs differ, so users must learn each
system by asking
  • How does the system accept queries? Commands?
    Forms? Menus? Command structure?
  • Can one search by Author? Title? Subject?
    Form/genre? Keywords? Combinations? Exact
    word-for-word matches?
  • Are Boolean searches allowed? Order of
    operations? Default AND or OR? How are search
    results displayed? In what order?
  • Are guides presented before actual listings of
    records? How do they divide up (organize)
    responses? How do you sift through a multiscreen
    response?
  • What kinds of information are included in records
    in the database? Is coded data translated in a
    meaningful way?
  • Is a record displayed in full or briefly, and
    what is included at each level of detail?

120
System designs differ, so users must learn each
system by asking
  • Do records contain subject data in the form of
    controlled vocabulary?
  • Does the system support controlled vocabulary by
    displaying relationships between subjects?
    (Broader, narrower, and related terms)
  • How are author searches interpreted by the
    system- exact match, near match, keyword?
  • Which keys on keywords have special functions in
    the system? (Ctrl, Alt)
  • How are hyphens, punctuation, symbols treated?
    Normalization algorithms?
  • Does the system remember where the user is in a
    search? Navigation?
