A brief CV
I came to academia late in life after an apparently random working life as a cinema projectionist, printer, editor, broadcaster, public servant
and union official.
When I look back on it the central thread has been one of information. Information in many forms, prepared using many techniques, delivered to differing numbers of people, to be used in different ways.
In 1994, I began to keep track of information systems journals, which resulted in the creation of the
Index of Information Systems Journals which has been in continuous operation
since then. It was only logical that when the Excellence in Research for Australia project came along, that I would be entangled in the
journal ranking and analysis side of it.
The need to categorise the journals in the Index lead to research into the way people perceive and categorise information.
To undertake that I have been using the literary ontology of Roman Ingarden and Boisot's Social Learning Cycle. The resulting thesis was awarded the 2012 ACPHIS medal for the Best Australian IS PhD Thesis. Here's a tag cloud of the thesis:

The cost in terms of the activities used to gain information is negligible compared to the
value of the information to which the perpetrators can gain access. The perception of the loss involved in such activities
has to shift to the value of information obtained. This change will more accurately reflect the loss that the victim has suffered.

The scholarly publication model is discussed and the impact of the current technological change on knowledge and communication generally on the scholarly publication model is set out. The proposal is made that rather than open access being the cause of the apparent and impending collapse of the scholarly publication industry, it is but one driver of a far wider change in scholarly publication. That change will have effects that extend well beyond the simple decision of whether a publication should be available by subscription or by one of the forms of open access. A number of other changes to scholarly publication are also itemized. The change is inevitable but its extent is as yet unclear.
Lamp J.W. & S.K. Milton (2012) "The social life of categories: An empirical study of term categorization."
Applied Ontology, 7(4), pp449-470
Most classification schemes in common use are actually categorization schemes which fall somewhere on a continuum between unstructured, uncontrolled lists of terms and formal classifications. Over time, terms change meaning and acquire new definitions. This paper presents the results of an approach that used the librarianship principle of consensus to form categories of terms and to relate those categories using a domain reference group. Boisot's Social Learning Cycle (SLC) was then used as a model with which to explain category variations. The single study undertaken in this investigation demonstrated the value of the SLC for explaining the variations between reference group members, and showed the potential for explaining category changes over time. This identifies areas in which consensus is breaking down or emerging, allowing for focused maintenance of categorical schemes. Applied Ontology website
Lamp J.W. & J. Fisher (2010) "ERA Distribution of Information Systems Journals"
Australasian Journal of Information Systems, 16(2), pp5-17
The Excellence in Research for Australia (ERA) initiative being conducted by the Australian
Research Council (ARC), mandates a single journal and conference ranking scheme over every academic
discipline in Australia. A universal publication outlet ranking list mandated by a government agency
is unique and has attracted interest and comment both within Australia and overseas. Equally, the
interest shown has come from all sectors involved in academic publishing - authors, reviewers,
publishers - and from commercial and open access publishers. This paper investigates the
distribution of information systems journals over the various ERA parameters and comments on a
claim of bias whereby the ranking of a journal is positively influenced by the number of years
it has been in existence in the areas of information systems and business journals. Clear evidence
of the diversity of the information systems discipline is observed. The benefits of a multidisciplinary
foundation for information systems is also noted. Longer established journals are shown to attract higher
rankings and possible reasons for and implications flowing from this are discussed.

The purpose of this article is to review and comment on the Australian Government's
entry into the journal ranking domain. It provides a review and reflection on the approach and potential impact of
the direction taken. This project is arguably the largest of its type and the effects on academic publishing and
the survival of journals could be far reaching. The article draws together current material on the Australian Government's
activities and provides details of the scope of the journal ranking project.

Since Fisher, Shanks, & Lamp (2007) was written and published further work has been
undertaken on the development of the Australian Information Systems Journal and Conference
Rankings list. More details became available late in 2007 on the DEST requirements relating to
journal and conference rankings for the RQF. A newly installed Federal Government resulted in the
abandonment of the RQF, replaced with ERA (Excellence in Research for Australia). It was
therefore appropriate to provide an update of the revised Ranking list and the process undertaken to
arrive at the updated list. Although the RQF in its current form has been abandoned, ERA also
requires a ranked journal list.

There has been an increasing focus internationally on the quality and impact
of research outputs in recent years. Several countries, including the United Kingdom and New
Zealand have implemented schemes to base the funding of research on research quality. The Australian government is planning to implement a Research Quality Framework (RQF) in the
next few years that will impact greatly on funding of research in Australian universities.
A key issue for Australian researchers is how the quality and impact of research is defined
and measured in their discipline areas. Although peer review is widely used to assess the
quality of research outputs, it is expensive and labour intensive. Other surrogate quality
measures are often used. This paper focuses on measuring the quality of research outputs
in the information systems discipline. We argue that measures such as citation indexes are
inappropriate for information systems and that the publication outlet is a more suitable indicator of quality. We present a ranking list of journals for the information systems
discipline, and discuss the approach we have taken in developing the list. We discuss
how the ranking list may be used in defining and measuring the quality of information systems
research outputs, the limitations inherent in the approach and discuss lessons we have
learned in developing the list.
Lamp J.W. (2007) "Perceptions of Gender Balance of IS Journal Editorial Positions"
Communications of the AIS, 20, pp124-133
An analysis of 18,854 editorial positions on IS journals was undertaken to
examine the perceived gender balance of those positions as an indication of their contribution
towards a positive role model for females considering an IS academic career. The nature and
extent of perceived gender balance is examined in terms of overall composition of editorial
positions, journal prestige and the specific area within IS covered by a journal. The results
indicate that perceived gender balance of editorial positions reflects that of ICT academia
generally, and that female representation appears to be concentrated in journals covering
areas that are traditionally seen as female occupations eg health, education, librarianship.
As such, little or no encouragement is given to females considering an IS academic career.
Lamp J.W. (2006) "Recognition as a distinguishing characteristic of IS journals"
Australasian Journal of Information Systems, Vol 13 No 2, pp7-16
The number of journals publishing information systems (IS) research has grown
dramatically over the past few decades. This has resulted in an environment where authors
have a wider choice of journals in which to place articles. Electronic journals are now as
readily recognised by authorities as print journals. This paper provides firm evidence in
support of the assertion that the number of journals publishing IS research have increased.
The paper also examines the Australian context where the selection of a journal in which to
place an article is influenced by recognition from the Department of Education Science and
Training (DEST). In Australia, obtaining DEST recognition as a recognised research journal
is not an onerous task, and yet a significant number of IS journals have not done this.
Publishing in a DEST recognised journal is essential for Australian researchers to contribute
to their organisation's research quantum and hence research funding. Attention is drawn to an
increasing number of IS journals not recognised by DEST, and consequent action is recommended.

Attempts to produce adequate and long-lived subject indexes of information systems and computer science
research have failed. In this paper we report preliminary results of an approach by which the terms expressed in
research literature, such as that in information systems, can be systematically and meaningfully categorised. The
approach is based on Roman Ingarden's ontological theory of the written scholarly work: its nature, existence,
and categorisation, and builds on Grounded Theory: a rigorous grounded qualitative research method
addressing how meaningful categories can be analysed from text and related to each other. We have found that
the key guiding unit of analysis operationalising Ingarden's approach through Grounded Theory is the "reported
research activity" and that the process is possible although labour intensive. On the basis of using the approach,
we propose simple steps to improve the quality of keywords in reported research.

Proceedings of the Eighteenth Australasian Conference on Information Systems, University of Southern Queensland, 478-486
The Research Quality Framework uses Thomson-ISI citation benchmarks as its main set of objective measures of research quality.
The Thomson-ISI measures rely on identifying a core set of journals in which the major publications for a discipline are to be found. The core
for a discipline is determined by applying a non-transparent process that is partly based on Bradford's Law (1934). Yet Bradford was not
seeking measures about quality of publications or journals. How valid then is it to base measures of publication quality on Bradford's Law?
We explore this by returning to Bradford's Law and subsequent related research asking "what is Bradford's Law really about?" We go further,
and ask "does Bradford's Law apply in Information Systems?" We use data from John Lamp's internationally respected Index of Information
Systems Journals to explore the latter question. We have found that Information Systems may have a core of journals only a subset of
which is also in the list of Thomson-ISI journals. There remain many unanswered questions about the RQF metrics based on Thomson-ISI and
their applicability to information systems.

Research into domain specific ontologies is difficult to treat empirically. This is because it is difficult to ground domain ontology while simultaneously being true to its guiding philosophy or theory. Further, ontology generation is often introspective and reflective or relies on experts for ontology generation. Even those relying on expert generation lack rigour and tend to be more ad-hoc. We ask how Grounded Theory can be used to generate domain specific ontologies where appropriate high level theory and suitable textual data sources are available. We are undertaking generation of a domain ontology for the discipline of information systems by applying the Grounded Theory method. Specifically we are using Roman Ingarden's theory of scientific works to seed a coding family and adapting the method to ask relevant questions when analysing rich textual data. We have found that a guiding ontological theory, such as Ingarden's, can be used to seed a coding family giving rise to a viable method for generating ontologies for research. This is significant because Grounded Theory may be one of the key methods for generating ontologies where substantial uniform quality text is available to the ontologist. We also present our partial analysis of information systems research.

Attempts to produce an adequate and long-lived subject indexing of information systems
research have failed. In this paper we seek to address this by proposing an approach by which the terms
expressed in research literature, such as that in information systems, can be systematically and
meaningfully categorised. The approach is significant in that it draws upon rigorous and philosophically
compatible bodies of work in two areas. Firstly, from work addressing the nature, existence, and
categorisation of literary expression found in research papers (Roman Ingarden's ontological analysis of
the scientific work of art). Secondly, from qualitative research methods addressing how meaningful
categories can be analysed from text and related to each other (Grounded Theory). The resulting approach
has potential to be applied in many scientific disciplines beyond information systems and form the
intellectual core of an information tool in e-Research.

fluence Creativity in Requirements
Engineering", Proceedings of the European Conference on Information Systems (ECIS2005), Regensburg, Germany.
In many disciplines, creativity has been recognised as an important part of problem solving.
In business, creativity enables the generation of better solutions and provides an opportunity
to gain a competitive advantage. In Information Systems (IS) creativity assists developers in
finding solutions to difficult problems by helping to efficiently utilise available resources and
allows the more effective planning and running of complex projects. One of the most
important aspects of IS development is Requirements Engineering (RE), the development
activity aimed at understanding the needs and wants of IS customers. While previous RE
researchers suggested that creativity is crucial in building high quality information systems,
fostering creative outcomes in RE is difficult as it is affected by the multifaceted socioorganisational
context within which IS development commonly takes place. This paper
reports findings from an empirical study into creativity in RE. Specifically, it reports various
contextual factors which were found to influence the creativity of individuals and their teams.

The examination of a practical issue with a web site has lead directly to the
consideration of the need for, and impact of, an approach based on fundamental theories of
"what is" to examine what information systems research is and the relations of the component
areas of endeavour. This paper presents an examination of the use of the philosophical field
of ontologies, and specifically the use of the ontological approaches upon which to base
categories of information systems research activities. This theoretical analysis is intended
to be used as the basis from which to develop a methodology to undertake the development of
the categorial scheme.

Development" Proceedings of the Fourteenth Australasian Conference on Information Systems

This paper discusses how interpersonal conflict between IS developers and clients can
disrupt IS projects. It is suggested how potential problems can be avoided by getting the 'soft' factors
right which can lead to improvements in information systems development (ISD) processes. However little
is being done in most organisations to review success from this perspective. Measurement of ISD quality
tends to favour the product rather than the human drivers that influence the development of the product.
Several ideas are put forward that can be used to resolve conflict and to better involve stakeholders
in the ISD process.

relatively large teams of between 9 and 16 and tackle a challenging, realistic
project during a single semester.

The rapid growth of the Internet and the ease with which
information can be provided via such services as the World Wide Web has created
a publication and information dissemination network with a highly chaotic
component. It is questionable whether the current practices, services and tools

which some order, quality assurance and scalability can be introduced into the

will also consider the implementation and impact of the NIB.

The need for the teaching of professional skills to
undergraduates in areas such as communications, team work, conflict resolution,
and ethics has for some time been articulated by the information systems
profession. These skills are particularly required by information systems
graduates. Changes to the traditional systems development life cycle towards
use of package software, prototyping, distributed computing, JAD etc have all
placed a further demand on interpersonal skills as opposed to technical skills.
While this need has been recognised by some universities, there have been a
number of approaches to the incorporation of these skills into the teaching
programme. This paper describes how professional skills teaching has been
introduced within the University of Tasmania's undergraduate programme.

This paper examines how object-oriented extensions to the Petri
Net formalism provide flexible structuring primitives which can aid the
modelling of network protocols. A key benefit is the support for incremental
modelling. As a result, a protocol can be modelled as a collection of services,
each of which can be expressed as the enhancement of a basic service, in which
case, both the structure of the basic service and the nature of the enhancement
can be clearly identified. More importantly, the evolution of a protocol
through a sequence of standards can be expressed by progressive refinements.
The object-oriented extensions are captured in the formalism of Object Petri
Nets, with a textual language form referred to as LOOPN++, both of which are
introduced in this paper. The incremental modelling capabilities and their
benefits are demonstrated for the Z39.50 Protocol for Information Retrieval.
Lamp, J.W. (2011) Information categorisation: an emergent approach University of Melbourne
The explosion of information and of naive users on the
Internet has highlighted problems of effective access to information. One response to
the problem of effective access to information is to classify the information into
categories based on the nature of the information being classified. Existing information
classifications are typically developed by committees or imposed by organisations and
have proved difficult to maintain. This investigation developed a two phase method to
systematically determine and analyse information categories in a specific domain as
perceived by domain experts. The initial phase, the Term Extraction Phase, applied the
librarianship approach of literary warrant guided by Ingarden's Ontology of Literature
to research papers from a specific domain to discover what is studied in the domain.
The approach is significant in that it draws upon rigorous and philosophically compatible
bodies of work in two areas. Firstly, from work addressing the nature, existence, and
categorisation of literary expression found in research papers. Secondly, from qualitative
research methods addressing how meaningful terms can be analysed in text and related to
each other. We have found that such a guiding ontological theory can be used to seed
coding families giving rise to a viable method for generating categorisations for further
research. We have also found that the key guiding unit of analysis operationalising
Ingarden's approach is the "reported research activity" and that the process is
practical although labour intensive. The second phase, the Term Categorisation Phase,
used the librarianship approach of consensus to have domain experts form categories
from the terms generated in the first phase. Examining those categories using pairwise
comparisons allowed the identification of similar categories based on the common
categorisation of terms in the coding family. The pairwise comparisons were undertaken
manually, but the development of an automated tool to perform these comparisons would
enhance this aspect of the phase. Boisot's Social Learning Cycle (SLC) was used as a
model with which to explain category variations. The single performance of the Term
Categorisation Phase undertaken in this investigation demonstrated the value of the
SLC for explaining the variations between domain experts, and showed the potential
for explaining category changes over time using the SLC and repeated performances of
the Term Categorisation Phase. This investigation makes a number of contributions.
The investigation demonstrated that the two librarianship approaches of literary
warrant and consensus are not necessarily mutually exclusive and that both have
much to offer at different stages of the categorisation process. A method was
devised which provides a more rigorous and systematic approach to analysing and
categorising text. The method consists of two phases which are loosely coupled and
could be used independently. A very significant aspect is the ability to view
categorisation as a dynamic process. That enables the examination of categorisation
and classification schemes and for the identification of areas within those schemes
which require attention. The method is not a tool to develop a complete classification
scheme, but seeks to contribute insights on how to progress the development of mature schemes.
