A Comparative Study to Analyze the Performance of Advanced Pattern Recognition Algorithms for Multi-Class Classification
2021
This study aims to implement the following four advanced pattern recognition algorithms, such as “optimal Bayesian classifier,” “anti-Bayesian classifier,” “decision trees (DTs),” and “dependence trees (DepTs)” on both artificial and real datasets for multi-class classification. Then, we calculated the performance of individual algorithms on both real and artificial data for comparison. In Sect. 1, a brief introduction is given about the study. In the second section, the different types of datasets used in this study are discussed. In the third section, we compared the classification accuracies of Bayesian and anti-Bayesian methods for both the artificial and real-life datasets. In the four…
Word sense disamibiguation combining conceptual distance, frequency and gloss
2004
Word sense disambiguation (WSD) is the process of assigning a meaning to a word based on the context in which it occurs. The absence of sense tagged training data is a real problem for the word sense disambiguation task. We present a method for the resolution of lexical ambiguity which relies on the use of the wide-coverage noun taxonomy of WordNet and the notion of conceptual distance among concepts, captured by a conceptual density formula developed for this purpose. The formula we propose, is a generalised form of the Agirre-Rigau conceptual density measure in which many (parameterised) refinements were introduced and an exhaustive evaluation of all meaningful combinations was performed.…
Passive in motion: the Early Italian auxiliary andare (‘to go’)
2014
The Italian construction andare ‘to go’ + (transitive) past participle expresses a passive meaning when occurring in a perfective past tense (1), whereas it conveys an additional deontic sense of (impersonal) obligation when used in an imperfective tense (2) (Bertinetto 1991; Giacalone Ramat 2000). A further constraint on the passive reading is represented by the semantics of the participle, necessarily expressing a negative value of ‘loss/destruction’; this value is moreover conceived as ‘non-intentional’, as the impossibility to express the agent (*da qualcuno) shows: (1) I documenti andarono distrutti. (*da qualcuno) the documents go. prf.3pl destroy.pst.ptcp.pl (by someone) ‘The documen…
Measuring Effort in Subprocesses of Subtitling
2021
There has been noticeable growth in the use and production of intralingual and interlingual subtitles due to technological advances and accessibility legislation. While the reception of subtitles has been increasingly studied over the years, there are only a few empirical studies that investigate the process of subtitling. This contribution gives initial results from a study that investigates the impact of reference material during post-editing of NMT of audiovisual content via language. The focus is on transcription and translation processes, the two main subprocesses of the complex task of interlingual subtitling. Applying well-established methods from TPR, key-logging and eye tracking, t…
Using a Computerised Corpus in the Construction of a Bilingual Phraseological Dictionary
2016
It is generally acknowledged that one of the main purposes of bilingual dictionaries is to provide learners with relevant and sufficient information about the grammatical, lexical and phraseological units of a language (Yong and Peng 2007: 20). Furthermore, this must be done in a way that is both convenient and comprehensible for very specific kinds of users (Cabre 2007: 80–81; Pecman 2008: 205), namely, non-native speakers who are still developing their linguistic and discourse competence but who have not fully attained the intuitive ability to tackle major grammatical issues. It follows that this kind of learner cannot rely on previous discourse experience and sociolinguistic training in …
Pronunciation Learning Strategy Chains: A Qualitative Approach
2014
Language learning is a daunting process frequently enhanced by a number of factors, for example, language learning strategies deployed in an orchestrated manner (Oxford 1990). Similarly, pronunciation learning may be supported by effective strategies used either separately or in logically combined chains. However, little attention has been given so far to the strategies L2 learners employ when learning the target language pronunciation, not to mention pronunciation learning strategy chains. Hence, there have been a limited number of empirical investigations into pronunciation learning strategies (PLS) in general and in particular the ones following the qualitative design (cf. Bukowski 2004;…
ERP qualification exploiting waveform, spectral and time-frequency infomax
2008
The present contribution briefly introduces an event related potential (ERP) detector. The specified detector includes three kinds of features of ERP. They are the ERP waveform feature, ERP spectral feature and ERP time-frequency feature respectively. According to these characteristics, two parameters are defined to reflect the timing feature of ERP. The mismatch negativity (MMN) is taken as the example to design an exact qualification detector. The experiment validates that the computer can automatically detect the raw trace to reflect the quality of the dataset, qualify the filtered trace to test whether the artifacts have been filtered out, and select the ERP-like component to reject art…
A practical solution to the problem of automatic word sense induction
2004
Recent studies in word sense induction are based on clustering global co-occurrence vectors, i.e. vectors that reflect the overall behavior of a word in a corpus. If a word is semantically ambiguous, this means that these vectors are mixtures of all its senses. Inducing a word's senses therefore involves the difficult problem of recovering the sense vectors from the mixtures. In this paper we argue that the demixing problem can be avoided since the contextual behavior of the senses is directly observable in the form of the local contexts of a word. From human disambiguation performance we know that the context of a word is usually sufficient to determine its sense. Based on this observation…
Automatic identification of word translations from unrelated English and German corpora
1999
Algorithms for the alignment of words in translated texts are well established. However, only recently new approaches have been proposed to identify word translations from non-parallel or even unrelated texts. This task is more difficult, because most statistical clues useful in the processing of parallel texts cannot be applied to non-parallel texts. Whereas for parallel texts in some studies up to 99% of the word alignments have been shown to be correct, the accuracy for non-parallel texts has been around 30% up to now. The current study, which is based on the assumption that there is a correlation between the patterns of word co-occurrences in corpora of different languages, makes a sign…
MultiROMs and Online Applications Used for Teaching Phonetics in a Secondary School: A Critical Review
2012
The aim of the article is to evaluate the quality of the materials used to teach pronunciation in a Polish secondary school. Although the analysis covers all kinds of aids available for teachers, including a coursebook accompanied by a CD, the authors focus mainly on MultiROMs and online resources connected with a given book. The findings allow the authors to conclude which coursebook sets seem to be most effective in shaping students’ pronunciation and which exercises are most helpful, taking into consideration the level of students’ English. Additionally, the authors’ idea was to check whether these books take into consideration the aspects of pronunciation which prove to be especially di…
