Dear Saket,

This problem has been addressed in psychology/psycholinguistics in the form of feature norm experiments, where participants are asked to list defining features for given words.

Data from some of these experiments is available online. See for example http://ppw.kuleuven.be/concat/workshop2007.php

Some people who have run such experiments: Ken McRae and Gabriella Vigliocco for English, and Sabine Schulte im Walde and Alissa Melinger for German.

All the best, Katrin
