Lexical resources are essential for the development of Natural Language Processing and all the applications that come from it, Information Retrieval, Information Extraction, Summarization, Question Answering, Sentiment Analysis, Conversational Assistants, etc.. Even for English, the most analyzed language, there are still some missing resources, the existing lexica are not inter-related and information that could, in principle, be obtained from pooling resources together is not readily available. The situation is much worse for Portuguese, where we lack big projects that accumulated resources such as WordNet, COMLEX, VerbNet, the Penn TreeBank, FrameNet, GATE, NLTK, MindNet, Delph-IN, ParGram, GF, etc. Together with colleages I've embarked in a long-term project of building lexical resources for Portuguese and making them open, so that others can build on them. Our basic strategy is to do as much as we can automatically, but to try to verify the automatically created data, to the best of our abilities. I will describe the tools we created and the ones we are working on and why.
OBSERVAÇÃO PARA VISITANTES:
