1. 21. Generalized Hebbian Algorithm for Dimensionality Reduction in Natural Language Processing

   Författare :Genevieve Gorrell; Arne Jönsson; Robin Cooper; Alexander Rudnicky; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Generalized Hebbian Algorithm; Language Modelling; Singular Value Decomposition; Eigen Decomposition; Latent Semantic Analysis; Vector Space Models; Computational linguistics; Datorlingvistik;

   Sammanfattning : The current surge of interest in search and comparison tasks in natural language processing has brought with it a focus on vector space approaches and vector space dimensionality reduction techniques. Presenting data as points in hyperspace provides opportunities to use a variety of welldeveloped tools pertinent to this representation. LÄS MER

3. 22. An Ontological Approach to support Knowledge Sharing between Product Design and Assembly Process Planning (APP)

   Författare :Baha Hasan; Jan Wikander; Mauro Onori; Jonathan C. Borg; Jos'e Barata; Pär Mårtensson; Monica Bellgran; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; knowledge sharing; Ontology; semantics; assembly knowledge; assembly design and assembly process planning.; Production Engineering; Industriell produktion;

   Sammanfattning : Modern manufacturing organizations have to cope with several critical issues arising from the need for mass customization such as short product life-cycles, an increasing number of product variants and frequently changing customer requirements. One of the main factors that could aid overcoming those challenges is the use of information and communication technology (ICT) applications over a collaborative manufacturing environment, in which all stakeholders share and exchange knowledge across different manufacturing domains and applications.

4. 23. Aspects of Declarative Memory Functioning in Adulthood : Cross-Sectional and Longitudinal Studies

   Författare :Michael Rönnlund; Elizabeth Maylor; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; aging; episodic memory; sematic memory; encoding support; crosssectional; longitudinal; Psykologi; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : The general objective of the thesis was to examine aspects of declarative memory functioning across the adult life span. The four papers were based on data collected as part of the Betula Prospective Cohort Study (Nilsson et al., 1997) and included largescale population-based samples of participants in the age range 35 to 90.

5. 24. Transitivity in discourse : A comparison of Greek, Polish and Swedish

   Författare :Ann Lindvall; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; agentivity; affectedness; aspect; boundedness; cognitive semantics; definiteness; discourse semantics; dynamism; functionalism; givenness; Greek; language typology; lexical semantics; modality; Modern Greek; Polish; transitivity; Swedish; translation; Linguistics; Lingvistik;

   Sammanfattning : This work assumes that various linguistic forms in different languages are related to common cognitive functions and semantic properties. A cognitive function - presumably universal - is information transmission. LÄS MER

7. 25. Efficient Communication via Reinforcement Learning

   Författare :Emil Carlsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Why do languages partition mental concepts into words the way the do? Recent works have taken a information-theoretic view on human language and suggested that it is shaped by the need for efficient communication. This means that human language is shaped by a simultaneous pressure for being informative, while also being simple in order to minimize the cognitive load. LÄS MER
