Knowledge Organization = Information Organization?
Abstract:
Are the terms ―information organization‖ (IO), ―organization of information‖ (OI) and ―information architecture‖
(IA) synonyms for knowledge organization (KO)? This study uses bibliometric methods, among others, to
determine some relations between these terms and their meanings. Apparently the data shows that these terms
should not be considered synonyms because each of the terms IO, OI, IA and KO produce a different set of high
ranked authors, journals and papers. In many cases the terms are, however, used interchangeably (and thus
indicating synonymity) and it is argued that the underlying theoretical principles are identical but that the different
terms tend to be applied in different contexts: KO in the library context; IA in the web-context and IO and OI in more
unspecified ways.
Introduction
The present study is concerned with the relations between four terms from the literature
of library and information science (LIS):
Information organization (IO),
Organization of information (OI),
Information architecture (IA) and
Knowledge organization (KO)
More precisely, it is about whether or not these terms should be considered synonyms?
Synonymy being defined as the semantic relation that holds between two terms that can—
in a given context—be said to express the same meaning. The term KO is well established
and the International Society for Knowledge Organization (ISKO) and its publications,
including the journal Knowledge Organization, are among the core actors in this field. IA,
on the other hand, is a rather new term, which in some contexts seems to be more ―hot,‖
technologically advanced or prestigious term. The two other terms: IO and OI are included
in this examination in order to clarify the meaning of closely related terms. Are there
differences in meaning or are the different expressions attributable, in part, to what Konrad
(2007) termed ―poor terminological hygiene‖? The methodology applied in this study is
also suggested for examining concepts and relations in other fields and it is therefore an
approach to KO applied on the field itself.
Method
Each of these four terms were searched in Social Science Citation Index (SSCI) both in the
whole database (Table 1) and limited to LIS (Table 2) in January 2011. For each term and
each database was ranked 1) the most cited authors 2) the most cited journals or works and
3) the most cited references. The content in these tables is analyzed. Core texts in KO and
IA are also examined in order to compare the theoretical issues involved.
Results
The rankings of the bibliometric investigation are displayed below.

Data Analysis
If we compare the five most cited authors in the whole of SSCI the first observation is that
there is no overlap: Each of the four concepts has a unique set of most cited authors (which
of course change if more than just the top five is considered; data not shown), seemingly
indicating that we are dealing with four separate fields.
a) The term KO is dominated by authors from LIS: The three most cited researchers in rank
#1 often attend the same conferences and publish in the same journals. Dahlberg is the
founder of the International Society for Knowledge Organization (ISKO) and the journal
Knowledge Organization. In rank #1 only Chi et al. (1981) and Kogut & Zander (1992) are
from outside LIS (respectively from cognitive science and knowledge management)
indicating that the term is also used in those fields. The first three are well known
researchers in LIS as are all researchers in rank #13. The three most cited journals are from
LIS: J.Doc, Knowledge Organization and JASIST. The fourth and fifth most cited journals
are from psychology (Cognitive Psychology) and Management (The Academy of
Management Review).
b) Concerning the term IO: Cognitive psychologist G.A. Miller was most cited in rank #4
(however in a new search made on 2012-01-02 Svenonius and Miller switched places).
Elaine Svenonius is a well know scholar in KO. Her book The Intellectual Foundation of
Information Organization (2000) is clearly a work from the tradition of LIS and KO, which
has chosen the label IO rather than KO (and therefore indicating synonymity between these
terms). Her book appears under both KO (rank 15) and IO (rank 6+18). Returning to rank
#4: A. Baddeley is a cognitive psychologist, while M.E. Porter and D.E.Z and are
management scholars. In the social sciences, the term IO is thus not dominated by LIS
11
researchers, and within LIS (rank #16) Nicolas Belkin and Peter Ingwersen are not foremost
known for their contributions to KO. C.W. Choo is researcher in knowledge management.
Arlene G. Taylor is a well-known author of a textbook in KO (Taylor & Joudrey, 2009). It
appears that IO is sometimes used as synonym for KO, but in general what is found under
that term is very mixed.
c) The term OI is mostly used by psychologists and cognitive scientists (whether or not
cognitive science is a fruitful theoretical basis for KO cannot be discussed in the present
paper). In Rank #7 none of the researchers are from LIS. In rank #19 Raya Fidel and
Barbara Kwasnik are from KO, the others from other subfields of LIS. This term is therefore
the term with the weakest link to KO and what is found under it is also very mixed.
d) Finally, the term IA designates what appears to be a ―new‖ field. A core text is
Morville & Rosenfeld (2006) (1st edition: Rosenfeld & Morville, 1998) and this text is the
highest ranking in both rank #11 and #23 just as one of the authors is the highest ranking
author in both rank #10 and #22. Although this book is focusing on web-design, it contains
a lot of traditional topics from KO, such as hierarchy, folksonomies, metadata, thesauri, and
faceted classification. I am not saying that nothing is new in this field (and it is certainly
attracting some talented people), but I would say that it is an exaggeration to speak of a
new field because the overlap with KO is high, and the intellectual basis is too closely
related (in other words: each field is too small in substantive content to be separated from
the other). In my opinion IA is to some extent ―old wine in new bottle‖ and the tendency to
create new labels may have some negative effects in fragmenting the field.
Discussion
Does KO = IO? What differences does it make whether we prefer the term knowledge or
the term information in LIS and in KO? There are different views on this issue in the
literature. D. A. Kemp (1988, p.3) argued that "knowledge retrieval" should substitute
"information retrieval"; Van Rijsbergen and Lamas, on the other side, wrote:
―In the early days of Information Retrieval (van Rijsbergen, 1979), people used to qualify their statements
about information retrieval (IR) by saying that really they were working on document retrieval. It was
denied strenuously that information was being retrieved. As Lancaster (1968) wrote, ―An information
retrieval system does not inform (i.e., change the knowledge of) the user on the subject of his inquiry. It
merely informs on the existence (or non-existence) and whereabouts of documents relating to his request.‖
The situation has changed. We believe that the purpose of an information retrieval system
is to provide information about a request and that a request is a representation of an
information need that an IR system attempts to satisfy.‖ (van Rijsbergen & Lalmas, 1996,
p. 386).
There are strong indications that the term ‗information‘ became popular with library
science and documentation more because of its appeal than for its scientific merits (cf.
Capurro & Hjørland, 2003; Hjørland, 2000; Furner, 2004). These authors, among others,
argue against van Rijsbergen & Lamas‘ point of view. A document can be said to
materialize the knowledge produced and thus to represent knowledge. Documents may also
be said to have the potential to inform people. The criteria of when documents represent
knowledge (what is knowledge?) or when documents inform people (what is information?)
have been the focus of much discussion. Buckland (2012), for example, finds that
information science is concerned with what people know (i.e., with knowledge), and his
arguments are related to a deeper concern about the fruitful development of LIS: it is rather
important issues that are at stake. It may be argued that knowledge and information can be
used as synonyms in LIS, and a textbook by Rowley & Hartley (2008) used the title
Organizing knowledge but adds the subtitle: An Introduction to Managing Access to
Information. In this way some authors may try to attract people whichever of these terms
12
they might prefer and again indicating the connection between the terms IO, OI, IA and KO.
I‘ll argue, however, that knowledge should be the preferred term in LIS—and thus that KO
should be preferred among the four terms considered in this article.
The present study has used bibliometric methods and has considered different disciplines,
which is a concept in the sociology of science. The methods and theories used here are thus
much more related to fields like ―the theory of knowledge‖ and ―the sociology of
knowledge‖ than to ―information theory‖, indicating an important relation to other
disciplines concerned with knowledge. My suggestion is, in other words, that the term
―knowledge‖ moves us relatively away from fields like information theory and computer
science towards fields such as social semiotics, science studies and the study of documents
and their role in human activities (―activity theory‖). I believe that such a ―social turn‖ is
very important for developing LIS as a scholarly discipline.
Subject terminology should not be used as buzzwords. There is a tendency to change
terminology in this way. Sheila Webber shows how many courses in England shift titles
from ‗information science‘ to ‗information management‘ simply because the word science
is not popular among the students that one wishes to attract. She wrote:
" In course names, Information Management is the phrase in the ascendant. This is most obvious when
looking at UK undergraduate course titles. . 'Engineering: Electrical and Information Sciences', which is
the only course [out of 74] to mention IS. None of the other courses use this phrase. 'Information
management' is the title of 38 courses. There are 18 course titles using the word 'studies', e.g. 'Information
Studies', 'Information and Library Studies'. Of the 56 courses mentioning information management or
studies, 45 are dual degrees with a subject obviously outside the discipline, e.g. 'Information Management
and Business Studies (the most popular combination)." (Webber, 2003, 325-326).
Webber finds that this tendency is an expression of a fad and an indication that the term
"management" is popular among students trying to choose an education programme while
the term "science" does not have the same appeal. She further puts the question (p. 328):
""Library and Information Management": is it merely an umbrella term and administrative
convenience? Is it a new name for IS [information science]? Is it a different discipline?" In
a similar way may many phrases containing the word ‗information‘ (i.e. ‗information
retrieval, information organization, etc.) are being used more because of their appeal than
their scientific merits. At the School of Information Studies at the University of Wisconsin-
Milwaukee, for example, the name of the subject has recently changed from KO to IO. This
is just a change in name, not a change in what is being taught. I do not believe that it is
healthy for scholarship to use terminology as buzz-words in order to attract students, to try
to raise the image of a dusty profession, to follow fad or whatever. I do not believe that
science and scholarship should be constructed on the basis of what can be sold. It is the
other way round: Things should be sold because they have inherent qualities, which the
broader society learns to respect and in this way making the names of the fields popular.
An analysis of the theoretical problems involved demonstrates that all of the fields: KO,
IO, OI and AI are primarily concerned with subjects, concepts, and semantic relations
between concepts. The basic theoretical knowledge is therefore the same in the fields
covered by the four terms, although IA is more about organizing subjects and concepts on
the web, whereas KO has traditionally been more (but not exclusively) related to libraries
and bibliographic databases. However, from the perspective of academic research, such
differences are superficial, not essential.
In a thesaurus for the domain of LIS, Knowledge organization (KO) should therefore be the
preferred term (descriptor), while the other examined terms: IO, OI and IA should be lead-in
terms (also termed non-preferred terms, synonyms, non-descriptors or entry terms).

Conclusion
This study has argued that it might be a good idea to continue to use the term knowledge
organization and to connect KO better with other disciplines devoted to the study of
knowledge.
The study has also explored the contextual issues related to the use of the four terms KO,
IO, OI and AI. Philosopher Wittgenstein is famous for his ―use theory‖ of meaning: You
have to study the use of language in order to understand its meanings. Miller & Leacock
(2000) raised the following question: ―Why isn‘t a dictionary a good theory of the lexical
component of language?‖ The answer they provide is that dictionaries lack contextual
information that would enable a user to make the correct association between senses and
actual contexts. They provide the example, Our families erode a lot, which sounds bizarre
until you read the definition of erode: ‗eat out, eat away‘. Thesauri—and most kinds of
knowledge organization systems (KOS)—also lack such contextual knowledge (this is not,
however, the case with, for example, historical dictionaries which may provide detailed
information about how words have been used).
The shortcoming of traditional KOS may be countered by bibliometric studies such as the
one made in the present article: this is a way to examine the terms in different contexts in
which their meanings are negotiated and may be more or less stabilized (KO and IA seem
rather stabilized compared to IO & OI). The study has thus demonstrated how bibliometrics
─ accompanied with a study of the contents of the most cited works ─ may be used in order
to study how concepts are used in different fields and thereby as a tool for organizing
knowledge.
