2. 1. Bootstrapping Named Entity Annotation by Means of Active Machine Learning

   Author : Fredrik Olsson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; corpus creation; data annotation; active learning; named entity recognition; machine learning; computational linguistics; natural language processing; information refinement;

   Abstract : This thesis describes the development and in-depth empirical investigation of a method, called BootMark, for bootstrapping the marking up of named entities in textual documents. The reason for working with documents, as opposed to for instance sentences or phrases, is that the BootMark method is concerned with the creation of corpora. READ MORE

4. 2. Analysis of large-scale metagenomic data

   Author : Fredrik Boulund; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; DNA analysis; big data; antibiotic resistance; hidden Markov models; high-performance computing; distributed computing; distributed computing;

   Abstract : The topic of this thesis is the analysis of large data sets of DNA sequence data produced from modern high-throughput DNA sequencing machines. Using such machines to sequence the genetic content of a microbial community produces a metagenome. This thesis comprises three research papers, all connected to the study of large metagenomic data sets. READ MORE

5. 3. The role of fault management in the embedded system design

   Author : Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Management; Resilient system; Recovery methodology.; Computer Science; datavetenskap;

   Abstract : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.

   Abstract : Introduction: This compilation licentiate thesis focuses on open government data (OGD). The thesis is based on three papers. OGD is a system that is organized when publishers collect and share data with users, who can unrestrictedly reuse the data. In my research, I have explored why it can be challenging to cultivate OGD.

7. 5. Business Intelligence Utilisation through Bootstrapping and Adaptation

   Author : Wanda Presthus; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Business Intelligence; Utilisation; Bootstrapping; Adaptation; Installed Base; Information Infrastructure;

   Abstract : Business Intelligence (BI) has traditionally been viewed as a technology-driven, rational process, which would lead to better decision-making in organisations. Fact-based decisions are expected to reduce costs and increase income for a company, but also, for example, prevent crime and illness on a more global scale. READ MORE
