The work gives overview of its three main topics: semantic web, information extraction and ontology learning. A method for identification relevant information on web pages is described and experimentally tested on pages of companies offering products and services. The method is based on analysis of a sample web pages and their position in the Open Directory catalogue. Furthermore, a modfication of association rules mining algorithm is proposed and experimentally tested. In addition to an identification of a relation between ontology concepts, it suggest possible naming of the relation.

Traditionally manufacturing job shops either have a process layout or a product layout. The advantages of one type of layout tend to be a disadvantage for the other. Hybrid cellular constructs represents a novel fusion of process and product layouts. In this thesis, hybrid cellular constructs specifically Hybrid Flow Shops and Reoriented andamp; Reshaped Cells are clearly described in terms of their structure, key features, and modes of operation. An engineering procedure is illustrated by cases and particular manufacturing circumstances where each concept would be most useful are identified. This thesis then defines the lean practices that are compatible with the structure in question and identifies what practices are incompatible. It suggests how to modify lean practices to fit and at least obtain some benefits for the incompatible ones. Finally, a procedure for design of logistics management systems for assembly cells and lines is presented.

We investigate a new approach for SMT system training within the streaming model of computation. We develop and test incrementally retrainable models which, given an incoming stream of new data, can efficiently incorporate the stream data online. A naive approach using a stream would use an unbounded amount of space. Instead, our online SMT system can incorporate information from unbounded incoming streams and maintain constant space and time. Crucially, we are able to match (or even exceed) translation performance of comparable systems which are batch retrained and use unbounded space. Our approach is particularly suited for situations when there is arbitrarily large amounts of new training material and we wish to incorporate it efficiently and in small space. The novel contributions of this thesis are: 1. An online, randomised language model that can model unbounded input streams in constant space and time. 2. An incrementally retrainable translationmodel for both phrase-based and grammarbased systems. The model presented is efficient enough to incorporate novel parallel text at the single sentence level. 3. Strategies for updating our stream-based language model and translation model which demonstrate how such components can be successfully used in a streaming translation setting. This operates both within a single streaming environment and also in the novel situation of having to translate multiple streams. 4. Demonstration that recent data from the stream is beneficial to translation performance. Our stream-based SMT system is efficient for tackling massive volumes of new training data and offers-up new ways of thinking about translating web data and dealing with other natural language streams.

No. of bitstreams: 1 Cristina Mayer.pdf: 1995903 bytes, checksum: 09a2f90db9b38ad6cba6cbb1553e52b5 (MD5) Previous issue date: 2018-08-31 / Conselho Nacional de Pesquisa e Desenvolvimento Científico e Tecnológico - CNPq / The main goal of this research was to look at Web text varieties, specifically in social networks and consumer generated content such as comments, reviews and complaints in English through the Multidimensional Approach (MD) for register variation analysis leading to a set of dimensions of variation across Web registers. Web registers have been the object of several MD investigations (BERBER SARDINHA, 2014; BIBER et al., 2015; BIBER; EGBERT, 2015, 2016); however, these studies have not focused on social networks and consumer generated content. To fill this gap, a corpus of 15 of these registers was designed and compiled, the CoUGC – Corpus of User Generated Content, and three separate multidimensional analyses (MD) were conducted on the corpus, as well as a canonical correlation analysis. The first one was the additive MD analysis, in which the registers were added to the Dimensions of Variation of English by Biber (1988). The second one was a ‘mainstream’ MD analysis, in which the coocurrence of lexicogrammatical variables was analyzed and 4 dimensions were interpreted, representing the functional parameters underlying the variation across the registers. The third analysis, in turn, was based on the traditional MD analysis; however, it was conducted with lexical variables (BERBER SARDINHA, 2014; 2017; no prelo). This analysis revealed 5 thematic dimensions, which reflected semantic groupings. A canonical correlation analysis was then run to explain the relationship between the functional and lexical dimensions. All the analyzes led to the study of the use of the language by Web users / O objetivo principal desta pesquisa foi o estudo de variedades de texto da web, especificamente em redes sociais e conteúdo gerado por consumidores, como comentários, críticas e reclamações em língua inglesa por meio da Abordagem Multidimensional (AMD) para análise de variação de registro, que leva a um conjunto de dimensões de variação de registros da web. Os registros da web foram objeto de várias pesquisas em AMD (BERBER SARDINHA, 2014; BIBER et al., 2015; BIBER; EGBERT, 2015, 2016). No entanto, esses estudos não tiveram como foco redes sociais e conteúdo gerado pelo consumidor. Para preencher essa lacuna, um corpus de 15 desses registros foi desenhado e compilado, o CoUGC - Corpus of User Generated Content e três análises multidimensionais (AMD) foram realizadas no corpus, além da análise de correlação canônica. A primeira foi a AMD aditiva, na qual os registros do corpus de estudo foram mapeados nas Dimensões de variação do inglês de BIBER (1988). A segunda foi uma análise AMD funcional tradicional, na qual foi analisada a coocorrência das variáveis lexicogramaticais e foram identificadas 4 dimensões, que representaram os parâmetros funcionais subjacentes à variação entre os registros. A terceira análise, por sua vez, baseou-se na AMD tradicional, entretanto com variáveis lexicais (BERBER SARDINHA, 2014; 2017; no prelo). Essa análise revelou 5 dimensões temáticas, que refletiram agrupamentos semânticos. Foi feita então uma análise de correlação canônica para a observação da relação entre os dois conjuntos de dimensões, funcional e lexical. Todas as análises permitiram o estudo da linguagem dos usuários da web
