  applications relevant to digital libraries and
  library services.
• Topic Map was searched in the following Dbs
• Academic OneFile
• JSTOR

Libraries
5
Lourdi, 2006 A multi-layer metadata schema for
digital folklore collections

• Topic Maps helpful for managing heterogeneous
  collections
• Ex Digital folklore collections
• Handwritten texts
• 3D Objects
• Sound recordings

• Discusses
• Interoperability between metadata schemas
• Presents
• Topic Map approach for developing metadata
  mappings

6
Inglesias, 2007 Topic maps and the ILS An
undelivered promise

• Overview of current Topic Map use in library
  field
• As part of ILS
• Addresses Topic Maps
• Potential
• Challenges

• Findings
• Converting MARC data into Topic Map standard is
  difficult
• Vendors and libraries need to find ways to
  structure data for easier conversion
• Unnecessarily-high barrier to entry
• More training material and software needed

Searching
8
Yi, 2008 Information organization and retrieval
using Topic Maps-based ontology results of a
task-based evaluation

• Question
• How does a Topic Maps-based ontology approach
  affect users searching performance?
• Recall Search time
• Compared to thesaurus-based retrieval system

• Results
• Topic Maps-based ontology had significant and
  positive effect on both recall search time
• Implications
• Information Retrieval System designs would
  benefit from a Topic Maps-based ontology

Dotsika, 2010 Semantic APIs Scaling up towards
the Semantic Web

• Topic Maps are similar to Resource Description
  Framework (RDFs)
• Semantic Applications Programmers Interface (API)
• Turns unstructured text (from websites, etc.)
  into a contextual framework
• Information discovery
• Generates XML code (mostly RDF)

11
Dotsika, 2010 Semantic APIs Scaling up towards
the Semantic Web

• Topic Maps API
• Topic Map API Interfaces (In development)
• User-friendly topic map applications (in
  development)
• Semi-automatically generate Topic Maps
• Currently no Semantic APIs supporting Topic Maps

• Topic Maps Semantic Tagging
• Not yet standardized
• High level of modeling power / granularity
• No browser support, XHTML attributes
• Medium level of simplicity
• Moderate implementation costs

12
Newman, 2010 Visualizing search results and
document collections using topic maps

• Explores 2D visualizations of Topic Map search
  results
• Visualizing document collections reveals semantic
  structure
• Allows a better understanding of an entire set of
  results

• Vis. Doc. Collns (Contd)
• Avoids search results that are too broad or too
  narrow
• Allows better understanding of relationships
  between various lines of research

13
Newman, 2010 Visualizing search results and
document collections using topic maps

• Discussion
• Techniques for assessing Topic Maps validity and
  accuracy
• Challenges of producing useful 2D maps of
  documents

• Conclusions
• Global Topic Map visualizations less useful
• Local Topic Map visualizations better for
  navigating collections
• Shows only a few dozen closely related documents

14
Kim, 2007 A methodology for constructing of
philosophy ontology based on philosophical texts

• Method for using Topic Maps to construct a
  philosophy ontology based on philosophical texts
• Ontology
• Explicit formal specification of terms, which
  represent the intended meaning of concepts, in
  the domain and relations among them.

• Primary goal of ontology
• Share and reuse domain knowledge among people or
  machines, i.e. software
• Crucial factor for the success of many
  knowledge-based applications
• Semantic Web
• Data Warehouse
• Knowledge Mgmt. Sys.
• E-Commerce
• E-Learning

15
Kim, 2007 A methodology for constructing of
philosophy ontology based on philosophical texts

• Problem
• Developing ontologies within real-world knowledge
  domains takes huge efforts
• Solution?
• Ontology mgmt. system based on Topic Maps

• Mgmt. system can be applied to other learning
  domain ontologies
• History
• Literature
• Arts
• Music

16
Dotsika, 2009 Uniting formal and informal
descriptive power Reconciling ontologies with
folksonomies

• Ontologies and folksonomies are currently the
  webs main classification schemes
• Ontologies formal, top-down, slow-growing
• Folksonomies informal, bottom-up, fast-growing
• Adoption of a standard to reconcile the two
• Create quality assurance
• Enhance web information quality and findability
  

17
Dotsika, 2009 Uniting formal and informal
descriptive power Reconciling ontologies with
folksonomies

• Available standards
• Topic Maps
• RDFs
• Problem
• Ontologies and folksonomies are too different
• No common framework for quality assurance possible

• Interim-Solution
• Attempt to identify requirements for integrating
  ontologies and folksonomies

18
Learning
19
Dicheva, 2006 TM4L Creating and browsing
educational topic maps

• Information seeking
• Task-performing information support
• Information need, task-oriented, requiring a
  strategy
• Difficult on Web
• Results often inaccurate, biased, dated, or
  superficial

• Ontologies can aid information seeking
• Concepts relations-driven
• Improves info. exploration
• Topic Maps as ontologies for Web learning
• Framework for TM-based Learning Repositories
• TM4L

20
Shih 2007, Organizing learning materials through
hierarchical topic maps An illustration through
Chinese herb medication

• Topic Maps for digital learning
• Compiling diverse material
• Comprehensive view of concepts and their
  interrelationships

• Self-Organizing Maps (SOM) and Topic Maps
• Both text-mining techniques
• Used together
• Automatically generate professional learning
  materials
• Turn large amounts of information into useful
  learning resources ()

21
Venkatesh, 2008 Topic Maps as indexing tools in
E-Learning Bridging theoretical practical gaps
between information retrieval and educational
psychology

• Investigates the use of topic map technologies in
  an online course management system
• Case study
• 38 graduate students
• Topic Map in use at large N. American University
• Assignment browse repository of essays to
  compile ill-structured essay task
  

22
Venkatesh, 2008 Topic Maps as indexing tools in
E-Learning Bridging theoretical practical gaps
between information retrieval and educational
psychology

• Results (gathered from interviews and log files)
• Topic Maps semantic nature
• Improved performance and task understanding
• Enabled pursuit of distinct browsing paths based
  on individual level of task understanding

• Topic Maps useful for Course Mgmt. Systems
• Subject-centric
• Identifies core concepts
• Searchability
• Associative
• Links topics for easy knowledge-acquisition
• Classificatory
• Allows for step-by-step learning approach
