CrePS Projects

Here are some systems I implemented to set up and investigate a framework for Creative Problem Solving (CrePS), together with relevant papers.

comRAT – C is a system that can solve the Remote Associates Test – in its compound form. The Remote Associates Test is a creativity test of the following form – given words:

MEDAL  –  LINING  –  BULLET

what is a word that relates to all three?1

comRAT can solve these problems and create new Remote Associates Tests. If you want to read more about comRAT, this is a short paper on it:

  • Oltețeanu, Ana-Maria and Falomir, Zoe (2014) – Towards a Compound Remote Associate Test Solver based on Language Data. In Proceedings of the Catalan Conference of Artificial Intelligence, Frontiers in Artificial Intelligence and Applications, IOS Press. DOI: 10.3233/978-1-61499-452-7-249

For an ampler treatment of it you can read this more advanced paper online:

new! comRAT – V – We have recently extended this work towards the visual domain. For example, a visual query in the same style would look like this:

question-1-glove-handle-pen

Can you tell what the answer is?2

A paper reflecting this work has just been presented. I will put up a link to this as soon as it is available:

  • Oltețeanu, Ana-Maria, Gautam Bibek and Falomir, Zoe – Towards a Visual Remote Associates Test and its Computational Solver, in: Proceedings of the International Workshop of Artificial Intelligence and Cognition, AIC 2015

OROC is a system that can do creative Object Replacement and Object Composition. Thus OROC can answer question of the type:
– what can I use to put a nail in the wall if I don’t have a hammer? AND
– what can I make a Hammer from?

OROC has been evaluated with the Alternative Uses Test. This is a test for divergent thought/creativity in which the participant is given an object, let’s say Stone, and is asked to come up with as many uses as possible for that object. For example: a stone can be used as a paperweight, a stone can be used to put nails in the wall, etc.

The evaluation of the Alternative Uses Test is partly done with human judges. If you want to be a judge and also answer a few queries for yourself go here. More about OROC can be read here:

Radicioni, Cognitive Systems Research, vol. 39, pp. 15-32 . doi:10.1016/j.cogsys.2015.12.011

CreaCogs is the theoretical framework under which these systems and other forthcoming ones are built. CreaCogs is a creative problem-solving framework emphasizing a type of knowledge organisation which allows restructuring and re-representation.

These papers present the framework and its principles in theoretical and then more formal terms:
