We introduce an alternative approach to ex- tracting word pair associations from corpora, based purely on surface distances in the text. We contrast it with the prevailing window- based co-occurrence model and show it to be more statistically robust and to disclose a broader selection of significant associative re- lationships - owing largely to the property of scale-independence. In the process we provide insights into the limiting characteristics of window-based methods which complement the sometimes conflicting application-oriented lit- erature in this area.
