Meaning-Text Theory
During some recent reading, it struck me that a useful framework for thinking about and talking about sentence generation is the MTT or “meaning-text theory” of Igor Mel’cuk, et al Here is one readable reference:
Igor A. Mel’čuk and …

Semantic dependency relations
I spent the weekend comparing the Stanford parser to RelEx, and learned a lot. RelEx really does deserve to be called a “semantic relation extractor”, and not just a “dependency relation extractor”. It provides a more abstract, …

Sentence Patterns
I’ve recently resumed work on the question-answering chatbot, and am trying to get it to comprehend a broader range of questions and statements. The “big idea” is to create a number of “sentence patterns” that the pattern matcher can …

scheme shell
I needed the ability to hand-edit opencog data while other processes were running. And so I hacked with guile for a while, and now there’s a scheme shell for opencog.
