Handling disfluencies in spontaneous language models
No full textIn automatic speech recognition, a stochastic language model (LM) predicts the probability of the next word on the basis of previously recognized words. For the recognition of dictated speech this method works reasonably well since sentences are typically well-formed and reliable estimation of the probabilities is possible on the basis of large amounts of written text material. However, for spontaneous speech the situation is quite different: disfluencies distort the normal flow of sentences and written transcripts of spontaneous speech are too scarce to train good stochastic LMs. Both factors contribute to the poor performance of automatic speech recognizers on spontaneous input. In this paper we investigate how one specific approach to disfluencies in spontaneous language modeling influences recognition performance.status: Publishe
Linguistic knowledge and word sense disambiguation
No full textThe main research question I try to answer in the my thesis is which linguistic knowledge sources are most useful for word sense disambiguation (WSD), more specifically word sense disambiguation of Dutch. The goal of the project was to develop a tool which is able to automatically determine the meaning of a particular ambiguous word in context, a so called word sense disambiguation system. In order to achieve this, I make use of the information contained in the context, namely the words surrounding the ambiguous word, and additional underlying information (such as syntactic class and structure) to build a statistical language model. This model is then used to determine the meaning of examples of that particular ambiguous word in new contexts.
My results on the (unseen) Senseval-2 test data show that adding structural syntactic information in the form of dependency relations instead of PoS of the context leads to an error-rate reduction of 8% for the word form model. Furthermore, the lemma-based approach (introduced in this thesis) outperforms the word form-based approach independently of the features included in the model. We can observe an error rate reduction of 10% with regard to the lemma-based model including PoS in context, and a reduction of 6% of errors with regard to the best model based on word forms.
Comparing the results on the test data to results obtained with a different system, using Memory-Based Learning (MBL) as a classification algorithm, both the word form-based classifiers and the lemma-based classifiers from my system produce higher accuracy. The lemma-based model actually leads to an error rate reduction of 10% if compared to the MBL WSD system.
In my maximum entropy system, especially the addition of deep linguistic knowledge greatly improves accuracy. In combination with an approach taking advantage of morphological information, the lemma-based approach, the best results for WSD of Dutch on the Senseval-2 data set are obtained. Our system achieves significantly higher disambiguation accuracy than any results for Dutch that have been reported in the literature up to now and is thus state-of-the-art for Dutch WSD.
Core technologies for conjunctively written South African languages
No full textDuring this SADiLaR funded project, enriched corpora for the four official South African languages with a conjunctive orthography,
i.e. isiNdebele (NR), isiXhosa (XH), isiZulu (ZU), and Siswati (SS) was developed. The corpora consist of approximately 50,000 tokens,
parallel on sentence level, with English as source language, for each language. Each language’s corpus was annotated on three levels, namely morphological analysis, part of speech and lemmatisation (see: https://repo.sadilar.org/handle/20.500.12185/546).
Using the annotated data, 12 core technologies, i.e. morphological analysers, POS taggers and lemmatisers for each of the four languages were developed and packaged in a single graphical user interface (UI)
Misplaced Women?
No full textMisplaced Women? is an ongoing interdisciplinary art project (2009-2017) by Tanja Ostojić that has been conceived as both an internet—platform and a real platform organized in public spaces in the cities across the globe to discuss the issues of migration, displacement, security, privacy, and exposure. It is manifested in a series of performances by the author herself, as well as delegated performances, individual or group performances predominantly by women, and performance workshops conducted by Tanja Ostojić herself. Essentially, the performance score might include unpacking, rummaging and detailed searching of the entire content, pockets, purses, wallets, personal suitcases and bags on sites that are relevant to migration, such as airports, train stations, Western Union Money Transfer services, police stations for foreigners who want to obtain residence permits, etc. Participants performing at authentic locations might repeat similar actions that build upon the basic proposal of the Misplaced Women? concept, i.e. they deal with positions andexperiences of people in transit, migration, and exile.Misplaced Women? is an ongoing interdisciplinary art project (2009-2017) by Tanja Ostojić that has been conceived as both an internet—platform and a real platform organized in public spaces in the cities across the globe to discuss the issues of migration, displacement, security, privacy, and exposure.
