Semantics
- When you describe something as a small set of objects and
actions, you are defining the semantic space.
- The real world isn't like that.
- As you scale up, you'll suffer from the symbol grounding problem.
- What does this symbol mean.
- At the last research away day, I ended up speaking with David Turner
about meaning.
- David knows some stuff about Formal Semantics
- I got into CAs from Natural Language Processing, trying to get
a handle on meaning or Natural Semantics
- Classic Logic is all about symbol manipulation.
- The symbols aren't grounded in reality.
- CAs on the other hand can be grounded in reality.
- You don't define a "dog", you learn the concept through
seeing lots of instances of it.
- Resolving the meaning problem by hooking up with reality is
a nice way to solve the semantics problem.
- CAs thus can solve problems that symbol systems just won't
encounter.
- HCI people might ask why did they not try that link, they tried all
the others? They forgot. They didn't recognise it. CAs will
provide new answers.
