A natural language parser that could extract noun phrases for all medical texts would be of great utility in analyzing content for information retrieval. We discuss the extraction of noun phrases from MEDLINE, using a general parser not tuned specifically for any medical domain. The noun phrase extractor is made up of three modules: tokenization; part-of-speech tagging; noun phrase identificati...

This paper describes a system that resolves prepositional phrase attachment ambiguity in English sentence processing. This attachment problem is ubiquitous in English text, and is widely known as a place where semantics determines syntactic form. The decision is made based on a four-tuple composed of the head verb of the verb phrase, the head noun of the noun phrase, and the preposition and hea...

This paper introduces a new, unsupervised algorithm for noun phrase coreference resolution. It differs from existing methods in that it views coreference resolution as a clustering task. In an evaluation on the MUC-6 coreference resolution corpus, the algorithm achieves an F-measure of 53.6%, placing it firmly between the worst (40%) and best (65%) systems in the MUC-6 evaluation. More importan...

In this paper we argue that the concept of reprojection, often applied in the verbal domain, should be extended to the nominal domain. We develop an analysis according to which a moved N does not adjoin to a functional category; rather, it moves out of its projection and remerges with it. This movement is (indirectly) triggered by a certain kind of categorial probe feature that we call “Münchha...

Abstract Complex noun phrases (NP) are central to mature academic writing and often a focus of explicit teaching. The National Curriculum in England, for example, requires specific components NP complexity be taught at educational stages. However, the evidence base such practices is unclear. Research on emergence both limited dated. Moreover, some work has suggested that development late-occurr...

Adjectives in Basaá [ɓasaá] (Bantu, A43: Cameroon) are morphologically nominal: they possess inherent noun class and distinguish singular and plural (Dimmendaal 1988, Hyman 2003). Additionally, adjectives in Basaá function as the head of their noun phrase, in a sense to be made precise below. This challenges the standard assumption that noun phrases or DPs are projected (or headed) by nouns. Th...
