Eta photoproduction study with the upgraded Glasgow tagger at MAMI
… by the Glasgow Photon Tagging Spectrometer (the “tagger”). The upgrade of MAMI necessitated the corresponding upgrade of the tagger. The work of this thesis included assisting in the upgrade and calibration of the tagger before using the completed spectrometer in the measurement of differential …

Searching for exotic Higgs boson decays using a low mass double b-tagger
… and application of a newly developed double b-tagger for use in the context of exotic Higgs decays. After the discovery of the Higgs boson at the Large Hadron Collider, an effort to measure its properties in detail has ensued. Current measurements only constrain non- Standard Model or “exotic” …

An Evaluation of POS Taggers for the CHILDES Corpus
<p>This project evaluates four mainstream taggers on a representative collection of child-adult’s dialogues from Child Language Data Exchange System. The nine children’s files from Valian corpora and part of Eve corpora have been manually labeled, and rewrote with LARC tagset. They served as gold …

Creating large semantic lexical resources for the Finnish language
… to contribute to the development of a semantic tagger for Finnish. This tool is a parallel of the English Semantic Tagger which has been developed at the University Centre for Computer Corpus Research on Language (UCREL) at Lancaster University since the beginning of the 1990s and which has over …

Part-of-speech tagging and partial parsing for Irish using finite-state transducers and constraint grammar
… texts. Following this, we describe our POS tagger for Irish, implemented using Constraint Grammar Disambiguation Rules, and vislcg2 software. The POS tagger currently achieves an f-score of 95% on development data and 94.35% on unseen test data. This tagger has been used to tag the 30 …

Improving a supervised CCG parser
… in CCG parsing. First, we test novel supertagger-parser combinations to identify the parsing models and algorithms that benefit the most from recent gains in supertagger accuracy. Second, we attempt to lessen the future burdens of assembling a state-of-the-art CCG parsing pipeline by …

Answering definitional questions before they are asked
… constructs, with the help of a part-of-speech tagger and a named-entity recognizer. My system, named CoL. ForBIN, extracts entities and their definitions, and stores them in a database. This reduces the task of definitional question answering to a simple database lookup.

Classification of semantic relations in different syntactic structures in medical text using the MeSH hierarchy
… a set of doctors' notes using a part of speech tagger and a parser. Each compound was labeled with a semantic relationship, and each word in the compound was mapped to its corresponding entry in the MeSH hierarchy. MeSH includes only medical terminology so it was extended to include everyday, …

Sentence Simplification for Text Processing
… resources used to train and evaluate this sign tagger (Chapter 2) and the machine learning method used to implement it (Chapter 3). The second syntactic analysis method exploits the sign tagger and identifies the spans of compound clauses and complex NPs in input sentences. In Chapter 4 of the …

Imputation of Microsatellite Markers With Tag SNPs
… data. We investigate four imputation methods: Tagger, Vertex Discriminant Analysis (VDA), IMPUTE2, and BEAGLE. We achieve an accuracy of 93% with VDA in our subsample of Caucasians with manual 5-HTTLPR genotypes. Further, we find that for the entire Caucasian subsample without manual genotypes, …

Automatic Lexicon Generation for Unsupervised Part-of-Speech Tagging Using Only Unannotated Text
… as a component of an unsupervised part-of-speech tagger, making it truly unsupervised, requiring only unannotated text. The algorithm is discussed in detail, along with its background, and its performance. Experimentation shows that the proposed algorithm performs within 3% of the baseline, the …

The effects of part–of–speech tagging on text–to–speech synthesis for resource–scarce languages
… are not trivial. Firstly, an automatic tagger is required to tag the text to be synthesised with POS categories, but state-of-the-art POS taggers are data-driven and thus require large amounts of labelled training data. Secondly, the subsequent processes in TTS that are used to apply the …

A corpus-trained parser for systemic-functional syntax
