What Are Topic Maps?

• The GPS of the information universe
• A Topic Map is a network of
• topics
• associations (between topics)
• occurences (of topics)

Development of Topic Maps

The TAO of Topic Maps

• The basic building blocks are
• Topics e.g. Puccini, Lucca, Tosca
• Associations e.g. Puccini was born in Lucca
• Occurrences e.g. http//www.opera.net/puccini/bi
  o.html is a biography of Puccini
• Each of these constructs can be typed
• Topic types composer, city, opera
• Association types born in, composed by
• Occurrence types biography, street map,
  synopsis
• All such types are also topics (within the same
  topic map)
• Puccini is a topic of type composer and
  composer is also a topic

The upper layer consists of topics and
associations Topics represent the subjects that
the information is about Like the list of topics
that forms a back-of-book index Associations
represent relationships between those subjects
Like see also relationships in a back-of-book

knowledge layer
The lower layer contains the content usually
digital, but need not be can be in any format or
notation can be text, graphics, video, audio, etc.

• Occurrences are information resources that are
  pertinentto a given knowledge topic
• The links (or locators) arelike page numbers in
  aback-of-book index

Independence of topic associations topic
occurrences (information resources)
Topic maps as portable semantic networks
12
The IFS of Topic Maps

• Subject identity
• Addressable and Non-addressable Subjects
• Ex
• subject is an information resource
• http//www.ontopia.net/tutorials/tm-intro.ppt
• subjects are not information resources
• Puccini, Lucca, Tosca, Madame Butterfly, love
  ......
• -gtuse Subject Indicators

13
Published Subject Indicators(PSI)

• A subject indicator that is published and
  maintained at an advertised address for the
  purpose of facilitating knowledge interchange and
  mergeability, either through topic maps or by
  other means.
• Ontology Mapping, Core Component, OASIS PSI .
