PyWordNet is a Python interface to the WordNet database of word meanings and lexical relationships. It presents a concise interface to WordNet, that allows the user to type expressions such as N['dog'], hyponyms(N['dog'] ), and closure(ADJ['red'], SYNONYM) to query the database.
html2db.xsl converts an XHTML source document into a Docbook output document. It provides features for customizing the generation of the output, so that the output can be tuned by annotating the source, rather than hand-editing the output. This makes it useful in a processing pipeline where the source documents are maintained in HTML, although it can be used as a one-time conversion tool too.
