  2. 1. Machine-Printed and Handwritten Ethiopic Script Recognition

    Author : Yaregal Assabie; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HMM; Handwriting Recognition; OCR; Direction Field Tensor; Ethiopic Character Recognition; Amharic Word Recognition; Structure Tensor;

    Abstract : A written language is represented by using machine-printed or handwritten symbols called characters. For automatic recognition of written languages, handwritten script can be captured offline (by a scanner) and online (by electronic digital devices), whereas machine-printed text is captured offline.

  4. 2. Hidden Markov models : Identification, control and inverse filtering

    Author : Robert Mattila; Bo Wahlberg; Eric Moulines; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hidden markov models; system identification; method of moments; inverse filtering; abdominal aortic aneurysm; medical; markov decision process; structure; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The hidden Markov model (HMM) is one of the workhorse tools in, for example, statistical signal processing and machine learning. It has found applications in a vast number of fields, ranging all the way from bioscience to speech recognition to modeling of user interactions in social networks. READ MORE

  6. 4. Intelligent semi-structured information extraction : a user-driven approach to information extraction

    Author : Anders Arpteg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificiell intelligens; Informaitonsåtervinning; Artificial intelligence; Computer science; Datavetenskap;

    Abstract : The number of domains and tasks where information extraction tools can be used needs to be increased. One way to reach this goal is to design user-driven information extraction systems where non-expert users are able to adapt them to new domains and tasks. READ MORE

  7. 5. Sustainable Competence Development of Librarians in Pakistan

    Author : Syed Rahmat Ullah Shah; Högskolan i Borås; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainable competence development; motivated learning; socio-cultural learning; Library and Information Science; Biblioteks- och informationsvetenskap;

    Abstract : This thesis investigates proactive learning and competence development among academic librarians in Pakistan. The concept of motivation comes out of McClelland’s need theory, while the idea of competence development in this thesis emerges from the continuous contact of a person with the professional learning environment.
