  1. 1. Can We Predict Business Cycles With Natural Language Processing?

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Albert Flak; [2021]
    Keywords : Business Cycles; Economic Narratives; Natural Language Processing NLP ; Latent Dirichlet Allocation LDA ; Word Embeddings;

    Abstract : For centuries, many economists have attempted to solve the puzzle of business cycles; what explains them, and is it possible to predict them? The great amount of electronically available textual data, together with the recent advancements in unsupervised natural language processing are bound to offer new ways of analysing these perennial questions. Inspired with the emergence of narrative economics as a new field of economic analysis, I propose a novel research design to computationally extract business cycle sentiment from textual data on economic expectations.

  2. 2. Evaluating the Trade-offs of Diversity-Based Test Prioritization: An Experiment

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Ranim Khojah; Chi Hong Chao; [2020-12-03]
    Keywords : Diversity-based testing; Test Case Prioritization; Natural Language Processing NLP ; Level of Testing LoT ;

    Abstract : Different test prioritization techniquesdetect faults at earlier stages of test execution. To this end,Diversity-based techniques (DBT) have been cost-effective byprioritizing the most dissimilar test cases to maintain effectivenessand coverage with lower resources at different stages of thesoftware development life cycle, called levels of testing (LoT).

    Abstract : Natural language processing (NLP) is a vibrant area of research with many practical applications today like sentiment analyses, text labeling, questioning an- swering, machine translation and automatic text summarizing. At the moment, research is mainly focused on the English language, although many other lan- guages are trying to catch up. READ MORE
