Modeling Time and Identity

I really like ideas described in this presentation by Rich Hickey.

Link on InfoQ:

One of the fundamental requirements for future computing: explicit representation of “values” and changes in time.

“… The future is a function of the past, it doesn’t change it …”

“… We associate identities with a series of causally related values …”

Presented ideas are very close to my own understanding of new subject-centric programming model

Paraconsistent Reasoning in Ontopedia

I did a short presentation about paraconsistent reasoning in Ontopedia on TMRA 2009.


  • Paraconsistent reasoning allows to collect assertions from
    various sources and “safely” infer new information
  • Paraconsistent reasoning works well together with constraint
    languages (such as TMCL)
  • Paraconsistent reasoning supports evolutionary approach to
    building large assertion systems
  • We do not need to “fix all errors” before we can reason
