1. 6. With or without context : Automatic text categorization using semantic kernels

   Författare :Johan Eklund; Högskolan i Borås; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; automatic text categorization; subject classification; machine learning; computational linguistics; support vector machines; semantic kernels; term weighting; divergence from randomness; Library and Information Science; Biblioteks- och informationsvetenskap;

   Sammanfattning : In this thesis text categorization is investigated in four dimensions of analysis: theoretically as well as empirically, and as a manual as well as a machine-based process. In the first four chapters we look at the theoretical foundation of subject classification of text documents, with a certain focus on classification as a procedure for organizing documents in libraries.

   Sammanfattning : This thesis addresses the topic of grounding in human-robot interaction, that is, the process by which the human and robot can ensure mutual understanding. To explore this topic, the scenario of a robot holding a presentation to a human audience is used, where the robot has to process multimodal feedback from the human in order to adapt the presentation to the human's level of understanding.

4. 8. Mining for Meaning : using computational text analysis for social inquiry

   Författare :Miriam Hurtado Bodell; Marc Keuschnigg; Måns Magnusson; Peter Hedström; Laura Nelson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Text-as-data; Analytical sociology; Meaning-making; Computational text analysis; Computational social science;

   Sammanfattning : People interpret their surroundings through associations, determining what they perceive as belonging or not belonging together. For instance, one individual may view immigrants as a beneficial addition to the domestic labor market, while another may perceive them as a threat to job opportunities for native citizens. LÄS MER

5. 9. Classification along genre dimensions : exploring a multidisciplinary problem

   Författare :Mikael Gunnarsson; Högskolan i Borås; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Library and Information Science; Biblioteks- och informationsvetenskap;

   Sammanfattning : This thesis treats the sociotechnical notion of genre as a conflation of a communicative situation and a community of practices involved in producing and using documents. It explores the ways in which documents may be mapped to the sociocultural contexts from which they emanate. LÄS MER

7. 10. A Utopian Quest for Universal Knowledge : Diachronic Histories of Botanical Collections between the Sixteenth Century and the Present

   Författare :Anna Svensson; Sabine Höhler; Peder Roberts; Sverker Sörlin; Dániel Margócsy; KTH; []
   Nyckelord :HUMANIORA; HUMANITIES; history of botany; utopia; Oxford University Botanic Garden; pressed plants in books; botanical collection; classification; herbarium; Global Plants; digitisation; database; conservation; natural dyeing; botanikhistoria; utopi; Oxford University Botanic Garden; pressade växter i böcker; botaniska samlingar; klassifikation; herbarium; Global Plants; digitalisering; databas; växtfärgning; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

   Sammanfattning : This thesis explores the history of botany as a global collection-based science by tracing parallels between utopian traditions and botanical collecting, from their sixteenth-century beginnings to the present. A range of botanical collections, such as gardens, herbaria and classification systems, have played a central role in the struggle to discover a global or universal scientific order for the chaotic, diverse and locally shaped kingdom of plants.
