I am looking for unsupervised methods for feature weighting in clustering of categorical data. I am very interested mainly in methods applied in subspace clustering of categorical data. Can anyone help me with some references of classical and recent methods? Clustering is not my field of expertise; due to this, I'm not sure if my references are the relevant ones.
Dear Joel,
Here are references of several some very cited papers that might be relevant for your needs.

Thank you, Yaakov.
I had already found some of these references. But, I'm not an expert in this field. And, due to this, I'm not so confident in my judgments about the relevance of them.
Your suggestions will be very helpful.
Two recent approaches were published in ICTAI 2014:
J. L. Carbonera and M. Abel, “Categorical data clustering:a correlation-based approach for unsupervised attribute weighting,” in Proceedings of ICTAI 2014, 2014.
