How can computers distinguish the coherent from the unintelligible, recognize new information in a sentence, or draw inferences from a natural language passage? Computational semantics is an exciting new field that seeks answers to these questions, and this volume is the first textbook wholly devoted to this growing subdiscipline. The book explains the underlying theoretical issues and fundamental techniques for computing semantic representations for fragments of natural language. This volume will be an essential text for computer scientists, linguists, and anyone interested in the...

Research in robust open-domain text processing has seen considerable progress in the last couple of decades. It is probably fair to say that language technology tools have reached satisfactory performance at the level of syntactic processing. Therefore, it is timelier than ever to consider deep semantic processing as a serious task in wide-coverage natural language processing. This is a step that requires the integration of syntactic parsing, named entity recognition, anaphora resolution, thematic role labelling, word sense disambiguation with fine-grained semantic analysis. Accurate...

This book is a collection of papers by leading researchers in computational semantics. It presents a state-of-the-art overview of recent and current research in computational semantics, including descriptions of new methods for constructing and improving resources for semantic computation, such as WordNet, VerbNet, and semantically annotated corpora. It also presents new statistical methods in semantic computation, such as the application of distributional semantics in the compositional calculation of sentence meanings. Computing the meaning of sentences, texts, and spoken or texted dialogue...

O Prolog e uma linguagem de programacao, mas uma linguagem pouco usual. A designacao "Prolog'' e abreviatura de "Programming with Logic'' e a relacao com a logica e o que da ao Prolog o seu perfil especial. No seu amago esta uma ideia surpreendente: nao dizer ao computador o que fazer. Em vez disso, descrevem-se as situacoes relevantes e a computacao e efetuada quando se fazem perguntas. O Prolog deduz novos factos acerca das situacoes descritas e devolve essas deducoes como respostas. Porque aprender Prolog? Em primeiro lugar, a sua divisa "dizer qual e o problema em vez de dizer como o...
