Nope. Parts of speech of words are ambiguous and you need some statistical method of disambiguation. Plus, you need something to guess the possible tags for unknown words (e.g. speakers of English are able to guess that 'supercalifragilistiexpialigetic' is an adjective even when they see it for the first time because they can generalize from other words with -etic. Still, I wouldn't call part-of-speech tagging parsing. Here's some parsing demo: http://nlp.cs.berkeley.edu/Main.html#parsing http://nlp.cs.berkeley.edu/Main.html#parsing
