Networked Information Resources

1
Networked Information Resources

• Information about information indexing, tagging,
  and social bookmarking

2
Human-literature interface

• Central concern of information science the
  effective intermediation between people and
  literature

3
What causes the concern

• Information overload
• Specialized knowledge, fragmented literature

4
Information overload

• What information consumes is rather obvious it
  consumes the attention of its recipients. Hence
  a wealth of information creates a poverty of
  attention, and a need to allocate that attention
  efficiently among the overabundance of
  information sources that might consume it
• Herbert Simon (as quoted by Hal Varian in
  Scientific American, Sept. 1995).

5
How literatures are integrated

• Review articles, meta-analysis (e.g. Annual
  Review of Genomics and Human Genetics )
• Special issues (e.g. Nucleic Acids Research
  annual database issue JASIST bioinformatics
  issue)
• New disciplines (e.g. Bioinformatics Computers
  Chemistry)
• Citations indexing
• Subject Indexing and descriptive cataloging
  (human and machine)
• Knowledge discovery systems (e.g. collaborative
  filtering, Arrowsmith)
• book buying network
• 
  

6
Bibliographic control

• Describing
• Descriptive cataloging
• Subject indexing
• Citation indexing
• Exploiting (traces of evidence)
• How

7
New forms of bibliographic analysis

• Citation/link analysis (bibliographic coupling,
  co-citation coupling, author co-citation
  analysis)
• Collaborative filtering (behavioral and social
  aspects)
• Swansons undiscovered public knowledge

Author Co-citation Analysis

• Clustered configurations of names often reveals
  shared schools of thought or methodological
  approach, collaborative and student-mentor
  relationships, ties of nationality and other
  relationships

11
Resource representation discovery

• Machine/automatic indexing
• Human generated metadata (prepared by authors,
  users, indexers)

12
Metadata

• Metadata is structured information that
  describes, explains, locate, or otherwise make it
  easier to retrieve, use, or manage an information
  resource.

13
Indexing languages

• Natural language (machine extracted terms from
  document, e.g. Google and other full-text search
  engines)
• Controlled vocabulary (used by the indexer to
  create bibliographic records e.g
  http//www.ulcc.ac.uk/unesco/
• Folksonomy (user generated terms for resources
  sharing e.g. http//www.librarything.com/ )

14
Folksonomy

• combining "folk" and taxonomy, refers to the
  collaborative but unsophisticated way in which
  information is being indexed on the web. Instead
  of using a centralized controlled vocabulary,
  users are encouraged to assign freely chosen
  keywords (called tags) to pieces of information.
• e.g.
• http//del.icio.us/
