In this article we describe a retrieval schema which goes beyond the classical information retrieval keyword hypothesis and takes into account also linguistic variation. Guided by the failures and successes of other state-of-the-art approaches, as well as our own experience with the Irena system, our approach is based on phrases and incorporates linguistic resources and processors. In this respect, we introduce the phrase retrieval hypothesis to replace the keyword retrieval hypothesis. We suggest a representation of phrases suitable for indexing, and an architecture for such a retrieval system. Syntactical normalization is introduced to improve retrieval effectiveness. Morphological and lexico-semantical normalizations are adjusted to fit in this model. 相似文献

Donald Norman changed and continues to change the way in which we live our technology-infused and technology-based lives. Norman was one of the founders of the field of cognitive science and based on that work, he went on to create the field of user-centered design. It is the latter work for which he was awarded the 2006 Benjamin Franklin award in Computer and Cognitive Science. When one works within the paradigm of user-centered design, technology is created so that it is based on human cognitive capabilities, and is therefore, usable.1 When technology is not designed in this way, it is often experienced as unusable.In creating the field of user-centered design, Donald Norman works at a conceptual level; his influence is therefore both widespread and profound. 相似文献
