The Natural Language and Speech Group at the University of Lisbon's Department of Informatics provides several online linguistics tools for processing text. The Sentence Chunker tool marks sentence and paragraph boundaries and unwraps sentences split between lines. Tokenizer segments text into lexically relevant tokens.
Some of the provided tools are designed specifically for use with the Portuguese language. These tools include a Part-of-Speech (POS) Tagger, a Constituency Parser, and a Computational Grammar for language processing. These services can be accessed via the LX-Center SOAP API.
The following is a list of how-to and tutorial content that matched your search term. ProgrammableWeb's how-to content comes from two sources; full-blown tutorials that we publish ourselves and other highly relevant tutorials that we find elsewhere on the Web. This list represents on combination of both tutorial types and if you go to ProgrammableWeb's API University, you'll not only be able to find more, they are organized based on your role (API providers or developers who consumes APIs). If you know of a tutorial that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
