We propose that similarity is determined by the transformation distance between representations: entities which are perceived to be similar have representations which are readily transformed into one another, whereas transforming between dissimilar entities requires many transformations. We present three experiments that indicate that similarity is strongly influenced by transformation distance...

According to the transformational approach to similarity, two objects are judged to be more similar the simpler the transformation of one of the object representations into the other. This approach draws inspiration from the mathematical theory of Kolmogorov complexity, but otherwise remains an informal theory to this day. In this paper we investigate several different ways in which the informa...

Predicting entailment between two given texts is an important task upon which the performance of numerous NLP tasks depend on such as question answering, text summarization, and information extraction. The degree to are similar has been used extensively a key feature in much previous work predicting entailment. However, using similarity scores directly, without proper transformations, results s...
