    Scalable Text Mining with Sparse Generative Models

    No full text
    The information age has brought a deluge of data. Much of this is in text form, insurmountable in scope for humans and incomprehensible in structure for computers. Text mining is an expanding field of research that seeks to utilize the information contained in vast document collections. General data mining methods based on machine learning face challenges with the scale of text data, posing a need for scalable text mining methods. This thesis proposes a solution to scalable text mining: generative models combined with sparse computation. A unifying formalization for generative text models is defined, bringing together research traditions that have used formally equivalent models, but ignored parallel developments. This framework allows the use of methods developed in different processing tasks such as retrieval and classification, yielding effective solutions across different text mining tasks. Sparse computation using inverted indices is proposed for inference on probabilistic models. This reduces the computational complexity of the common text mining operations according to sparsity, yielding probabilistic models with the scalability of modern search engines. The proposed combination provides sparse generative models: a solution for text mining that is general, effective, and scalable. Extensive experimentation on text classification and ranked retrieval datasets are conducted, showing that the proposed solution matches or outperforms the leading task-specific methods in effectiveness, with a order of magnitude decrease in classification times for Wikipedia article categorization with a million classes. The developed methods were further applied in two 2014 Kaggle data mining prize competitions with over a hundred competing teams, earning first and second places

    This bibliography was compiled by two reference librarians, Patricia Dawson and David Hudson with the goal of making it easier of tracking down material on Iowa history and culture. This supplements the Iowa History Reference Guide published in 1952 by William Petersen

    The potential for using composted municipal waste in agriculture

    No full text
    This thesis addresses the relationship between urban waste and agriculture using an interdisciplinary systems approach. The environmental, economic, socio-cultural and political potential for using municipal waste compost (MWC) in urban and peri-urban agriculture in Accra, Ghana, was explored from different stakeholder perspectives and scales of enquiry. A pluralistic methodology was used in order to address different parts of the research and a critical reflection was made by the researcher on the carrying out of interdisciplinary research using these approaches. Waste management and composting practices were studied, as was urban and peri-urban agricultural systems. A series of farmer participatory experiments were carried out with urban vegetable growers to test the effects of using MWC from two different composting plants in Accra alongside current farmers’ practices. The perspectives of different stakeholders were also assessed through a combination of methods, including semi structured and informal interviews, participatory appraisal techniques, formal surveys, group discussions and workshops. Compost quality assessments revealed that the compost from the small-scale James Town plant was of higher quality than that produced at the large-scale Teshie/Nungua plant. Compost applications had a positive effect on crop growth. However, vegetable producers primarily used chicken manure as a fertility input and compared to this, the compost was inferior, particularly in relation to crop establishment and in creating a higher water demand. The growers were happy with the crop performance from compost, but saw the watering issue as a potential problem. They agreed that compost would be an attractive alternative during the rainy season. They also liked the fact that they did not need to apply compost to each crop, as they did with chicken manure. Whilst, growers would be willing to use and pay for MWC, both composts were too expensive to represent a viable alternative to other fertility inputs. However, given an appropriate blend of public-private-community partnerships and scales of operation which could harness opportunistic alignments between the needs of different actors, composting and its use in agriculture has potential in contributing towards sustainable development in the urban environment of Accra. With some modest policy support, the possibilities for improving quality and financial viability are considerable. Providing quality and price can meet the needs of growers, there is a market for MWC in Accra

    Translation and westernisation in Turkey (from the 1840s to the 1980s)

    No full text
    This thesis examines the role and function translations played in Turkish history, especially within the framework of its Westernisation movement from the mid-nineteenth to the late twentieth centuries. A descriptive approach is adopted, aiming to identify cultural patterns which shape and reflect translational decisions and help to a better portrayal of the socio-cultural context of translation during the time span examined. To this end, the thesis seeks to describe in detail historical, political, literary and linguistic factors which have affected the translation activity. The main assumption of this thesis is that acculturation was used as the main strategy in translations from Western languages during the periods which were marked with an extensive translation activity, especially during the nineteenth century and the first decades of the Republican era. This acculturation strategy not only helped to enrich the target literary system, bringing new literary models (genres), new subject matter, developing the language and giving rise to a new Turkish literature, it also had an effect upon the broader socio-cultural polysystem, especially on the process of identity creation. The analysis of the social, political and cultural conditions and policies suggests that the status given both to the source and target cultures has been the main factor for the acculturation. As examined in the last part of the thesis, a shift of power relations in the Turkish context, especially after the 1980s, marked a new kind of an acculturation strategy and a certain movement of resistance. The thesis concludes that there is need to know more about different translation histories in order to learn more about the acculturation process and to move beyond a Eurocentric view, and an interdisciplinary approach should be taken for such research

    Settlement & ceramics in Southern Iran: An analysis of the Sasanian & Islamic periods in the Williamson collection

    No full text
    Between 1968 and 1971, Andrew George Williamson carried out one of the most extensive and ambitious archaeological surveys undertaken in the Near East. Williamson’s survey of over 1,200 archaeological sites distributed widely through southern Iran represents the most detailed archaeological study of the region. Williamson's untimely death in Oman in 1975 prevented the work from being completed or published, and as a result, the information from his pioneering study have remained generally obscure. A sizable portion of the finds that Williamson collected during the survey (17,000 sherds) were exported to the UK and deposited at the Ashmolean Museum in Oxford, along with much of the documentation associated with the project. A full synthesis of this material has not until now been attempted. Recognising the important scientific value of Williamson's survey, a detailed study of the Collection was initiated with the aim of: 1) providing a complete catalogue of the Collection; 2) creating a list and map of all sites that Williamson visited and 3) analysing the resulting dataset. The discussion presented below, which describes the results of the research on the Collection, has been broken into two sections. The first section describes Williamson’s work and the contents of the Collection (Chapter 1), and explains the methodology and approach that has been taken during this study (Chapter 2). The second section uses the data generated from the study to analyse regional settlement trends (Chapter 3) and the changing distribution of a selection of key ceramic wares (Chapter 4). Together these themes contribute towards a model for the long-term economic development along the northern shores of the Persian Gulf, ๒ an area that has previously suffered from a major lack of primary archaeological research. Drawing on this study and the more detailed now be possible, for the first time, to set out a scheme that covers the Persian Gulf region as a whole
