UNIVERSITY OF GLAMORGAN
SCHOOL OF COMPUTING - HYPERMEDIA RESEARCH UNIT

3 year EPSRC Research Associate
Salary:  £15,205 - 23,199 depending on qualifications and experience.

For a project in collaboration with the Science Museum, unlocking access to
NMSI's collections database. The project explores how the semantic structure
underlying information can enhance intelligent browsing and search tools.
You should possess a postgraduate qualification or relevant experience in
computing or information science and a programming/database background. You
will join an active hypermedia research unit specialising in the cultural
heritage domain.


You will conduct independent research but also work as part of a team. You
will liase with the Science Museum, the mda, and other collaborators.
Knowledge of any of the following would be an advantage: database
programming; information science; thesaurus or classification theory; Museum
collections and IT. You will be expected to become familiar with previous
thesaurus research in information science and measures of semantic
closeness. You will design, program and evaluate research prototypes of
thesaurus-based retrieval tools employing semantic closeness measures. You
will conduct evaluations with users and analyse results. You will have the
opportunity to write and collaborate on academic publications.

Overview
Facilitating access to information is a topical concern. Major efforts are
underway to digitise collections for the Internet while existing databases,
previously the domain of the professional, are being opened to a new range
of users. Problems of information access are well known, and are heightened
when users are unfamiliar with indexing conventions. There is a critical
need for tools that will assist users to formulate and refine queries, and
navigate through information space. The recent growth of cultural heritage
applications has served as a major impetus in promoting access to multimedia
collections and has coincided with a concern by museums to rethink their
public role. As a result, there has been a move to unlock collections
databases to the public, which has foregrounded the question of 'access
points' and indexing practice.  One of the most commonly used controlled
vocabulary indexing tools is the thesaurus. More powerful use of thesauri in
retrieval is seen as key to widening  public access. Advantages of the
semantic relationships between index terms in faceted thesauri are widely
recognised, however their potential has yet to be realised in retrieval. The
project will identify heuristics to guide expansion of strings of query and
index terms, in order to yield a wider set of semantically close terms.
These will be applied in novel navigation and retrieval tools that are not
dependent on exact matching of keywords. The proposed research involves
close collaboration with the Science Museum in its attempts to promote wider
access to its collections database.
