I'm not doing any active work on it at the moment, but my favorite approach
has been Mark Jones' active production networks, which are one of those
schemes that lies in the twilight between symbolic and connectionist. Like
Copycat, it is based on a semantic net with spreading activation and variable
connection strengths. The network looks like the tree of a grammar, with lots
of extra links, and the text is fed in by sequentialy "lighting up" the
terminal nodes that correspond to words. After each one, the network
reconfigures itself to interpret the next word/phrase appropriately.
There is no formal distinction between nodes holding syntactic and semantic
information. Indeed, if you "light up" nodes corresponding to a semantic
situation, the network can be jogged to produce sentences describing it.
Sounds interesting. I found some papers on it, but couldn't locate a
home page for Jones or the software. Do you have any good URLs to
share that Google isn't coughing up?
