Overview

  • aim: to present the FCA as an applicable

method in the bibliometrics

  • method: Formal concept analysis (FCA)

Some Basic Objectives and Aims of Bibliographic Studies

  • citations and references (co-citations,

co-references)

  • co-authorship and scientific cooperation
  • journal impact factor

Some Basic Objectives and Aims of Bibliographic Studies

  • discovery of scientific influences and

knowledge flows

  • showing trends („hottest“ themes )
  • determining the influential journals, authors

and scientific ideas

  • strategic publishing

Quantitative and Qualitative Citation Analysis

Quantitative methods:

  • applying of statistical methods

Qualitative methods:

  • revealing of trends (citation or publication

trends, patterns of co-authorship)

  • visualisation – citation graphs, digrams

Formal Concept Analysis (FCA)

Formal Context Def.: A formal context K is a tripel (G,M,I) where

  • G is a set of objects
  • M is a set of attributes
  • I is a binary relation I ⊆ G×M

where (g,m) ∈ I is read as "object g has attribute m."

Formal Concept Analysis (FCA)

Formal Concept:

Def.: for A⊆G and B⊆M be A'={m∈M| ∀g∈A: (g,m)∈I} B'={g∈G| ∀m∈B: (g,m)∈I} Def.: (A,B) is a formal concept of the formal context (G,M,I) if A⊆G, B⊆M, A'=B and B'=A. A is called the extent and B the intent

  • f the concept.

SLIDE 12

Citation Analysis with FCA

  • The citation of a publication P is denoted by cite(P) or shorthand cP.
  • The intent of the object concept of cite(X), i. e. the citation of

publication X, is the set of publications citing X.

  • Example: The intent of the object concept c2 is {3,4,5,6}.
  • The extent of the atribute concept of a publication X is the set of

citations in X

  • Example: The extent of the atribute concept 3 is {c1,c2}.

Co-citation

  • Two publications are co-cited if

they both are cited by a third publication.

  • P,R∈Pub are co-cited iff

{cite(P), cite(R)}‘≠{}

  • Example:

1 and 2 are co-cited (both are cited by 3). cite(1)=c1, cite(2)=c2, {c1,c2}´= {3}

Petersen & Heinrich GFKL 2008 13

slide-14
SLIDE 14

Bibliographic Coupling

  • Two publications are

bibliographic coupled if they share a common reference

  • P,R∈Pub are bibliographic

coupled iff {P,R}´≠{}

  • The strength of the bibliographic

coupling is |{p,r}´| (the number of

references which both the publications share)

  • Example: 4 and 6 are

bibliographic coupled by c3, c2 ({4,6}´= {c3,c2}).

Co-autorship

  • The research: discovering and analising the scientific

cooperations in the field of bibliometrics

  • Query in Web of Knowledge:

informetr* OR bibliometr* OR scientometr* Result: 2460 Documents

  • Ranking of the authors and finding out who is the one

with the biggest sets of publications: Glänzel, W.

  • Exploring the cooperation patterns and showing a

method for the creating an author‘s cooperation profile

FCA in the Bibliometics - Advantages

  • an easy usage of different scales
  • allows a dynamic browsing of the data
  • shows logical implications
  • „Zooming“ – adding attributes or objects is

easy

Outlook

  • a model and a micro-bibliographic analysis
  • high potential for visualisation of citation

dependecies

  • mining logical connection in sets of

bibliographical data

  • FCA as a supporting method
  • tools for enrichment of bibliographical data

and for personal archiving
