kmeans generates ovelapping clusters

[djellel eddine Difallah]

Hello everyone,

I tried kmeans on some corpus with the same script as reuters but with -k 2

There are some terms in both generated clusters. In addition terms in a
cluster have a measure  .. somthing like   { .... animal:0.087, boat:3.559,
kitty:3.386, .....}

Isn't kmeans supposed to generate non overlapping clusters? and what does
that annotated measures mean?

Thanks !
