Siri don't parse

Siri is a natural language interface for the Apple iPhone 4S. It stands for Speech Interpretation and Recognition Interface and can answer your questions or make recommendations by delegating your requests to services on the web [ wiki link ]

Siri can’t parse pragmatics. The literal and rule-based contents of speech (semantics and syntax) are no problem. But the pragmatic content that’s supplied by context and culture is beyond Siri. However, roughly two-thirds of human communication requires intuiting one anothers meaning on a pragmatic basis [ thesis ]. We are pretty good at striking a balance between how specific and how general we need to be in order to keep the conversation rolling ..without either getting bogged down or sounding incomprehensible [ link ]. Computers on the other hand can’t do this. So, half the time I expect Siri to be either clueless ..or respond in gibberish.
