Expert and Corpus-Based Evaluation of a 3-Space Model of Conceptual Blending
This paper presents the 3-space model of conceptual
blending that estimates the figurative similarity between Input
spaces 1 and 2 using both their analogical similarity and the interconnecting
Generic Space. We describe how our Dr Inventor model
is being evaluated as a model of lexically based figurative similarity.
We describe distinct but related evaluation tasks focused on 1)
identifying novel and quality analogies between computer graphics
publications 2) evaluation of machine generated translations of text
documents 3) evaluation of documents in a plagiarism corpus. Our
results show that Dr Inventor is capable of generating novel
comparisons between publications but also appears to be a useful
tool for evaluating machine translation systems and for detecting and
assessing the level of plagiarism between documents. We also
outline another more recent evaluation, using a corpus of patent
applications
Can a Computationally Creative System Create Itself? Creative Artefacts and Creative Processes
This paper begins by briefly looking at two of the dominant
perspectives on computational creativity; focusing
on the creative artefacts and the creative processes respectively.
We briefly describe two projects; one focused
on (artistic) creative artefacts the other on a (scientific)
creative process, to highlight some similarities
and differences in approach. We then look at a 2-
dimensional model of Learning Objectives that uses independent
axes of knowledge and (cognitive) processes.
This educational framework is then used to cast artefact
and process perspectives into a common framework,
opening up new possibilities for discussing and comparing
creativity between them. Finally, arising from
our model of creative processes, we propose a new and
broad 4-level hierarchy of computational creativity,
which asserts that the highest level of computational
creativity involves processes whose creativity is comparable
to that of the originating process itself
Embedding a Creativity Support Tool within Computer Graphics Research
We describe the Dr Inventor creativity support tool that
aims to support and even enhance the creativity of active research
scientists, by discovering un-noticed analogical similarities between
publications. The tool combines text processing, lexical analysis and
computational cognitive modelling to find comparisons with the
greatest potential for a creative impact on the system users. A multi-year corpus of publications is used to drive the creativity of the
system, with a central graph matching algorithm being adapted to
identify the best analogy between any pair of papers. Dr Inventor
has been developed for use by computer graphics researchers, with
a particular focus on publications from the SIGGRAPH conference
series and it uses this context in three main ways. Firstly, the
pragmatic context of creativity support requires the identification of
comparisons that are unlike pre-existing information. Secondly, the
suggested inferences are assessed for quality within the context of a
corpus of graphics publications. Finally, expert users from this
discipline were asked to identify the qualities of greatest concern to
them, which then guided the subsequent evaluation task
