Citations and Research Evaluation

• The need for research evaluation
• Introduction of Web of Science in 2001
• Utilization as a research evaluation tool
• The number of citations received by papers
• Impact factor of the journalpublishing those
  papers

Perhaps a little excessive?
10
Cautions for Use of Citation Metrics

• Scope of journals included in the DB (Mostly
  European and American, Core journals only)
• Field-dependent differences (Circumstances
  surrounding paper/citations)
• The significance of citations (excessive
  self-citations, courtesy/critical citations)
• Slippage loss of counting due to variants and
  journal title changes

11
Cautions for Use of Impact Factors

• Average number of citations in the journal(not
  each paper )
• Different citation trends by document
  type(Review journals )
• Calculated for the past 2 years (Basic v.s.
  applied fields )
• Differences between general and specialized
  journals

12
2-Step Map

• Draw an arrow to the 2 highest citing journals
  (exclude self-citation)
• Avoid overlapping of the arrows
• Present each journal proportionate to its
  publication size

A 1.012
Receiving many arrows Core
B 2.345
C 3.242
13
Advantages of 2-Step Map

• Relationships between journals can be observed
  visually
• Tendencies that are often missed with citation
  metrics can be recognized
• Journals that receive many arrows Core journals
  ? journals with high impact factors

Advantages of Maps Based on Subscriptions

• Degree of availability of journals receiving many
  arrows
• Gaining an understanding of the importance of a
  journal
• Relationships between fields and balance of
  journals purchased

31
Assessment by Researchers

• Gaps between the arrow concentrations and their
  professional perceptions
• Are maps based on subscriptions limited?

32
Example Fisheries Science
Limnology and Oceanography
Marine Ecology Progress Series
33
What is Causing This Gap?

• Citation data for non-subscribed journals also
  needed?
• Citation data for related fields also needed?

• Comparison of this map to another map including
  all journals in the field

2-Step Map of the Overall Field

• Map of all journals in the field subscription
  information

• Facilitates the holistic picture of the field
• Helps to recognize essential journals that have
  not been subscribed

36
Effectiveness of 2-Step Map

• Visually recognize the trends that are difficult
  to be drawn by citation metrics alone
• Journals with high IF values ? Journals that
  receive many arrows
• Observe the relationships between journals and
  categories
• Observe the research trends within fields
• Utility in journal collection development by
  adding subscription information
• Utility for journal evaluation supplementing IF
  values

Researchers show high level of interest!
37
Issues Surrounding 2-Step Map

• Limitations due to JCR
• For 1-year sets of data, journals cited over a
  long period of time are not well presented
• Journals included in the JCR are limited
• Journals after title change are treated as new
  journals

38
Issues Surrounding 2-Step Map

• Difficulty in Extracting Appropriate Field
• Research fields becoming interdisciplinary and
  segmentalized
• JCR Category ? Research focus of your institution
  
• Complex nature of data extraction and map
  creation

39
Difficulty in Extracting Appropriate Field

• Graduate School of Agricultural Science(Plant
  sciences)
• Plant Sciences ? (Too broad)
• Agronomy ? (Content is irrelevant)
• Essential to know the research focus before
  starting!

40
Field Analysis Based on Journal Usage Survey

• Journals in Use (2005)
• Journals in which our faculty published their
  work
• Journals that were cited in their work
• Analysis of the use frequency and the fields of
  these journals

Effective Application to Library Collection
Development

• Determine the field(s) you wish to analyze
• Create a 2-Step map with all journals in the
  field(s)
• Add subscription information
• Add usage frequency information

46
Multiple Indicators for Collection Development

• Use a variety of indicators to make multi-faceted
  and comprehensive evaluation
• Associate with the characteristics of the
  research focus
• Also keep in mind the characteristics of each
  journal
• 2-Step Map
• Impact Factors (2, 5, 10 years)
• Statistics on Electric Journals usage (COUNTER)
• Researcher surveys

47
Conclusions

• Overcoming excessive reliance in impact factors
• Providing researchers with accurate information
• Enhancement of the JCR for utilization of
  multiple indicators
• Facilitating easier data extraction
• IF values longer than 2 years
• Refining category schemes
• Handling journal title changes
