Morphological Segmentation During Silent Reading
… tested two hypotheses about the properties of morphological segmentation: (a) that it applies on phonemic representations, and (b) that it outputs affixal information that is taken up and used at representational levels higher than the lexical one. In two experiments, participants' …

Morphological Segmentation in Czech using Word-Formation Network
Morfologická segmentace se zabývá dělením slov na morfémy - nejmenší jednotky nesoucí význam. Jedná se o nízkoúrovňový problém z oblasti zpracování přirozeného jazyka. Jelikož se morfologická segmentace někdy používá jako metoda předzpracování dat, její zlepšení může pomoci algoritmům řešícím …

Morphological segmentation : an unsupervised method and application to Keyword Spotting
… we present a new unsupervised algorithm for morphological segmentation that utilizes pseudo-semantic information, in addition to orthographic cues. We make use of the semantic signals from continuous word vectors, trained on huge corpora of raw text data. We formulate a log-linear model that …

Biases in segmenting non-concatenative morphology
Segmentation of words containing non-concatenative morphology into their component morphemes, such as Arabic /kita:b/ 'book' into root [check symbol]ktb and vocalism /i-a:/ (McCarthy, 1979, 1981), is a difficult task due to the size of its search space of possibilities, which grows exponentially as …

Unsupervised multilingual learning
… for core text processing tasks, such as morphological segmentation, part-of-speech tagging, and syntactic parsing. Besides these traditional NLP tasks, we also present a multilingual model for lost language deciphersment. We test this model on the ancient Ugaritic language. Our results …

Context-dependent type-level models for unsupervised morpho-syntactic induction
… methods for part-of-speech (POS) induction and morphological word segmentation by modeling linguistic phenomena previously not used. For both tasks, we realize these linguistic intuitions with Bayesian generative models that first create a latent lexicon before generating unannotated tokens in …

Coexistence of Slow Magnetoacoustic Waves and Thermal Limit Cycles in a Coronal Bright Point
… mechanisms. Our analysis method includes spatial morphological segmentation and running Fast Fourier Transform (FFT) techniques. For 37 regions of interest within a BP, the mean intensity of 171 and 193 Å EUV emissions are used to estimate the temperature and electron number density of the coronal …

Infixer: A Method for Segmenting Non-Concatenative Morphology in Tagalog
… I present a method for coercing a widely-used morphological segmentation algorithm, Morfessor (Creutz and Lagus 2005), into accurately segmenting non-concatenative morphological patterns. The non-concatenative patterns targeted—infixation and partial-reduplication—present problems for many …

Vessel identification in diabetic retinopathy
… in fundus photographs. It de-velops two vessels segmentation strategies and assess their accuracies. A literature review of retinal vascular segmentation found few results, and indicated a need for further development. The two methods for vessel segmentation were investigated in this thesis are …

Morphological Competence in English: Comparing Advanced L2 and L3 English Learners
This thesis compares morphological competence in advanced Mandarin-speaking second-language (L2) learners (n=63) and Uyghur-speaking third-language (L3) learners (n=40) of English, focusing on derivational word parts knowledge, morphological awareness, and processing ability. Existing research on …
