In Search of a Common Thread: Enhancing the LBD Workflow with a view to its Widespread Applicability
Literature-Based Discovery (LBD) research focuses on discovering implicit knowledge
linkages in existing scientific literature to provide impetus to innovation and research
productivity. Despite significant advancements in LBD research, previous studies contain
several open problems and shortcomings that are hindering its progress. The overarching
goal of this thesis is to address these issues, not only to enhance the discovery
component of LBD, but also to shed light on new directions that can further strengthen
the existing understanding of the LBD work
ow. In accordance with this goal, the thesis
aims to enhance the LBD work
ow with a view to ensuring its widespread applicability.
The goal of widespread applicability is twofold. Firstly, it relates to the adaptability of
the proposed solutions to a diverse range of problem settings. These problem settings
are not necessarily application areas that are closely related to the LBD context, but
could include a wide range of problems beyond the typical scope of LBD, which has traditionally
been applied to scientific literature. Adapting the LBD work
ow to problems
outside the typical scope of LBD is a worthwhile goal, since the intrinsic objective of
LBD research, which is discovering novel linkages in text corpora is valid across a vast
range of problem settings.
Secondly, the idea of widespread applicability also denotes the capability of the proposed
solutions to be executed in new environments. These `new environments' are various
academic disciplines (i.e., cross-domain knowledge discovery) and publication languages
(i.e., cross-lingual knowledge discovery). The application of LBD models to new environments
is timely, since the massive growth of the scientific literature has engendered
huge challenges to academics, irrespective of their domain.
This thesis is divided into five main research objectives that address the following topics:
literature synthesis, the input component, the discovery component, reusability, and
portability. The objective of the literature synthesis is to address the gaps in existing
LBD reviews by conducting the rst systematic literature review. The input component
section aims to provide generalised insights on the suitability of various input types in the
LBD work
ow, focusing on their role and potential impact on the information retrieval
cycle of LBD.
The discovery component section aims to intermingle two research directions that have
been under-investigated in the LBD literature, `modern word embedding techniques'
and `temporal dimension' by proposing diachronic semantic inferences. Their potential
positive in
uence in knowledge discovery is veri ed through both direct and indirect
uses. The reusability section aims to present a new, distinct viewpoint on these LBD
models by verifying their reusability in a timely application area using a methodical reuse
plan. The last section, portability, proposes an interdisciplinary LBD framework that
can be applied to new environments. While highly cost-e cient and easily pluggable, this framework also gives rise to a new perspective on knowledge discovery through its
generalisable capabilities.
Succinctly, this thesis presents novel and distinct viewpoints to accomplish five main
research objectives, enhancing the existing understanding of the LBD work
ow. The
thesis offers new insights which future LBD research could further explore and expand
to create more eficient, widely applicable LBD models to enable broader community
benefits.Thesis (Ph.D.) -- University of Adelaide, School of Computer Science, 202
