The interpretation of noun noun compounds
No full textThis thesis looks at conceptual combination, in particular it investigates how noun noun compounds are interpreted. Several themes run throughout the work. Real compounds (e.g. coat hanger, crab apple) are compared to novel ones (e.g. banjo cactus, zip violin). Also, compounds are examined in each of the possible permutations of artefacts (A) (e.g. coat, banjo) and natural kinds (N) (e.g. crab, cactus), (AA, AN, NA and NN).Experiments 1 - 4 examine noncompositionality in noun noun compounds. Possible sources of noncompositionality are investigated using both feature listing and feature rating tasks. Although some differences were found, results were similar between different types of compound, evidence of noncompositionality being found in each. The results also confirm that most of the meaning of a noun noim compound is derived from the second constituent (noun2).Experiments 5 and 6 look at two different types of compoimd interpretation - slot filling and property mapping. In experiment 5, slot filling is found to be the preferred interpretation type overall, but property mapping is more common in compounds composed of two natural kinds (NN). Experiment 6 examines possible factors influencing the choice between slot filling and property mapping interpretations. It was found that constituent similarity plays an important role, and also that this interacts with whether or not the constituents have important properties which clash. Experiment 7 looks at compound identification. Results suggest that the first constituent (nounl) may be critical in such tasks. Experiment 8 compares the importance of nounl and noun2 in determining the type of interpretation given to a compound. Neither position is found to be more influential than the other, although relational information does seem to be associated with specific nouns in each position. Throughout the thesis findings are related to current theories of conceptual combination, such as prototype models, the concept specialisation model and theories of compound interpretation by analogy
Empirical measurements of lexical similarity in noun phrase conjuncts
No full textThe ability to detect similarity in conjunct heads is potentially a useful tool in helping to disambiguate coordination structures - a difficult task for parsers. We propose a distributional measure of similarity designed
for such a task. We then compare several different measures of word similarity by testing whether they can empirically detect similarity in the head nouns of noun phrase conjuncts
in the Wall Street Journal (WSJ) treebank. We demonstrate that several measures of word similarity can successfully detect conjunct head similarity and suggest that the measure proposed in this paper is the most appropriate for this task
Noun, verb, and participation
No full textThe present article is a crosslinguistic discussion of the distinction between a word class of nouns and a word class of verbs in the UNI TYP framework of the dimension of PARTICIPATION (for a first overall sketch of PARTICIPATION see Seiler 1984). According to this framework the noun/verb-distinction (henceforth N/V-D) must be regarded as a gradable, continuous phenomenon ranging from the stage of a clear-cut distinction with no overlap to almost a non-distinction. Although there is no question that most, if not all, languages do differentiate between nouns and verbs, it is also quite apparent that the languages do so to a different degree and by different means, and that it only makes sense to use the terms "noun" and "verb" in different languages when one actually has a common functional denominator in mind (see below). After a general introduction to the notion of a noun/verb-continuum (chapter 1) the reader will be presented with a survey of languages as diverse as German. English, Russian, Hebrew, Turkish, Salish. and Tongan (see chapter 2) in support of the continuum hypothesis. In chapter 3 the facts are coordinated in an overall pattern of regularities underlying the Increase or decrease of categorical restrictions between the respective word classes. Also, chapter 3 raises the issue to what degree a N/V-D can be considered a matter of certain lexemes or a matter of the morphosyntactic environment of certain lexical units. Lastly, we shall seek for an answer to the question why it is not a necessary requirement for languages to draw a sharp distinction between a word class of nouns and a word class of verbs
Chapter 7. Multimodal noun phrases
No full textIn co-present interaction, our bodies are continuously available for sense- making. Linguists, however, have generally analyzed grammatical patterns, such as noun phrases, separately from the rest of human behavior. This chapter looks at a collection of cases in Swedish, English, and Estonian, where the speaker initiates a noun phrase but completes it with an embodied demonstration. Other participants treat this multimodal structure as complete and comprehensible. Building on earlier research on syntactic-bodily units (Keevallik 2013, 2017) this study calls into question the analytic boundary between language and the body and argues that grammatical projection cross-cuts modalities even within the assumedly robust noun phrase
AXEL: A framework to deal with ambiguity in three-noun compounds
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University, 6/12/2010.Cognitive Linguistics has been widely used to deal with the ambiguity generated by words in combination. Although this domain offers many solutions to address this challenge, not all of them can be implemented in a computational environment. The Dynamic Construal of Meaning framework is argued to have this ability because it describes an intrinsic degree of association of meanings, which in turn, can be translated into computational programs. A limitation towards a computational approach, however, has been the lack of syntactic parameters. This research argues that this limitation could be overcome with the aid of the Generative Lexicon Theory (GLT). Specifically, this dissertation formulated possible means to marry the GLT and Cognitive Linguistics in a novel rapprochement between the two.
This bond between opposing theories provided the means to design a computational template (the AXEL System) by realising syntax and semantics at software levels. An instance of the AXEL system was created using a Design Research approach. Planned iterations were involved in the development to improve artefact performance. Such iterations boosted performance-improving, which accounted for the degree of association of meanings in three-noun compounds.
This dissertation delivered three major contributions on the brink of a so-called turning point in Computational Linguistics (CL). First, the AXEL system was used to disclose hidden lexical patterns on ambiguity. These patterns are difficult, if not impossible, to be identified without automatic techniques. This research claimed that these patterns can assist audiences of linguists to review lexical knowledge on a software-based viewpoint.
Following linguistic awareness, the second result advocated for the adoption of improved resources by decreasing electronic space of Sense Enumerative Lexicons (SELs). The AXEL system deployed the generation of “at the moment of use” interpretations, optimising the way the space is needed for lexical storage.
Finally, this research introduced a subsystem of metrics to characterise an ambiguous degree of association of three-noun compounds enabling ranking methods. Weighing methods delivered mechanisms of classification of meanings towards Word Sense Disambiguation (WSD). Overall these results attempted to tackle difficulties in understanding studies of Lexical Semantics via software tools
Coordinate noun phrase disambiguation in a generative parsing model
No full textIn this paper we present methods for improving the disambiguation of noun phrase (NP) coordination within the framework of a lexicalised history-based parsing model. As
well as reducing noise in the data, we look at modelling two main sources of information for disambiguation: symmetry in conjunct structure, and the dependency between conjunct lexical heads. Our changes to the baseline model result in an increase in NP coordination dependency f-score from 69.9% to
73.8%, which represents a relative reduction in f-score error of 13%

Is the scope of phonological planning constrained by the syntactical role of the utterance constituents?
No full textFive experiments looked the effect of repeated phonemes in the production of color adjective+noun phrases in English ("green gun"), or noun+color adjective phrases in Spanish and French. Whereas phoneme repetition sped up naming latencies in the case of prenominal color adjectives, it induced inhibition in the postnominal case. We argue that these dissociation is not compatible with a genuine crosslinguistic difference in the scope of phonological encoding. Rather we explain it in terms of the interplay between an activation gradient, coding word order, and an activation bias, coding the syntactical role of the utterance constituents
Genitive quantifiers in Japanese as reverse partitives
No full textQuantificational determiners in Japanese can be marked with genitive case. Current analyses (for example by Watanabe, Natural Language and Linguistic Theory, to appear) treat the genetive case marker in these cases as semantically vacuous, but we show that it has semantic effects. We propose a new analysis as reverse partitives. Following Jackendoff (MIT-Press, 1977), we assume that partitives always contain two NPs one of which is phonologically deleted. We claim that, while in normal partitives the higher noun is deleted, in reverse partitives the lower noun is deleted
Employers’ Perception and Expectations of Professional Competency of Distance Learning Graduates: A Tracer Study of Nursing Graduates of the National Open University of Nigeria (NOUN)
No full textThis tracer study was designed to track National Open University of Nigeria (NOUN) graduate nurses in their places of work with a view to ascertaining their level of professional competency and to explore employers’ expectation of graduate competencies. The study employed the descriptive survey design. Participants included 222 NOUN alumni who graduated in nursing programme and a corresponding 222 heads/top-level managers of the organizations where the graduate nurses were employed. Multiple instruments were used to collect data including competency test, survey questionnaire, and direct observation. A number of remarkable findings emerged from this study, both expected and unexpected. Majority of sampled graduates appeared to possess high level of professional competency in all three competency dimensions measured. A significant proportion of employers seemed to hold high perception regarding the graduates. In matching the employers’ perception of ODL graduates against actual competencies of NOUN graduate nurses with the use of quadrant analysis, the resulting values showed that a significant proportion of the graduates met and exceeded employer expectation.</p
