I am back working as an AI researcher (after more than 2 decades working in academic IT). &lt;br /&gt;
&lt;br /&gt;
My previous foray into AI (from 1998 until 2001) included working with the Cyc ontology fairly intimately.&lt;br /&gt;
&lt;br /&gt;
I'm now wanting to understand a whole bunch of the underpinnings in terms of how data is handled (and/or might better be handled?) with regard to organization (categories, types, and some hard core computer science stuff that I'm very much in the beginning stages of learning).&lt;br /&gt;
&lt;br /&gt;
So I thought this list might be a good resource for at least a limited subset of all that I want to know more about.&lt;/div&gt;</summary>
