WebActually, what you suggest (converting categorical attributes to binary values, and then doing k-means as if these were numeric values) is another approach that has been tried before (predating k-modes).

WebFigure 7: Accuracy and MRR using the description of text and tf-idf feature weighting. This second model uses tf-idf weighting instead of binary weighting using the same description field. You can see that the accuracy is 0.63 and MRR is 0.51 a slight improvement. This is a good indicator that the tf-idf weighting works better than binary ...
