An Exploration of Representation Learning and Sequential Modeling Approaches for Supervised Topic Classification in Job Advertisements

This thesis applies the explorative double diamond design process borrowed to iteratively frame a research problem applicable in the context of a recruitment web service and then find the best approach to solve it. Thereby the problem focus is laid on multi-class classification, in particular the task of labelling sentences in job advertisements with one of six topics which were found to be covered in every typical job description. A dataset is obtained for evaluation and conventional N-Gram Vector Space models are compared with Representation Learning approaches, notably continuous distributed representations, and Sequential Modeling techniques using Recurrent Neural Networks. Results of the experiments show that the Representation Learning and Sequential Modeling approaches perform on par or better than traditional feature engineering methods and show a promising direction in and beyond research in Computational Linguistics and Natural Language Processing

The Politics of Financial Regulatory Reform

Financial regulators are key actors in a modern political economy given their role in determining the rules that govern savings and investments markets. This is an account of how two states, Britain and Germany, have sought to increase their oversight of financial markets by creating powerful new regulatory actors that are accountable to the political system. In both cases, this meant either ending or severe limiting the role of central banks and private actors as regulators. The aim is to show why domestic politics is key to understanding this major institutional change. Using a coalitional approach, this paper argues that politicians view the increased salience of financial regulation as a policy issue. The political response was triggered in large part by major changes in the composition of savings markets and the consequent privatization of risk , where voters are increasingly dependent upon financial markets in order to determine their future financial security. It argues that, for center-left parties, creating the new regulators allowed the parties to portray themselves as protecting the interests of voters while also appealing to more traditionally left suspicions about the power of both central banks and markets

Information Systems Methodologies in Use

Research into information systems development (ISD) methodologies is generally restricted to the creation or elaboration of methodologies or the provision of CASE support. This paper proposes that a fruitful area of research, which will provide insights into the effectiveness of ISD methodologies, must centre on the observation of the practice of systems developers, users and managers, and the study of methodologies in use. Such a programme requires certain techniques, ideally longitudinal ethnographic case studies. Preliminary results from a couple of case studies indicate that ISD methodologies are not used as prescribed but this does not necessarily prevent the successful completion of development projects
