1. 1. Studies in knowledge representation : modeling change - the frame problem : pictures and words

   Författare :Lars-Erik Janlert; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analogical; artificial intelligence; digital; exemplification; frame problem; Goodman; knowledge representation; metaphysics; model; pictorial representation; symbol theory;

   Sammanfattning : In two studies, the author attempts to develop a general symbol theoretical approach to knowledge representation.The first study, Modeling change -the frame problem, critically examines the - so far unsuccessful - attempts to solve the notorious frame problem. LÄS MER

3. 2. Notations supporting knowledge acquisition from multiple sources

   Författare :Åke Malmberg; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Knowledge Acquisition; Knowledge Representation; Expert Systems; Knowledge Engineering; XML; Distributed Systems; Knowledge Repository; Presence; SGN; Informatics; computer and systems science; Informatik; data- och systemvetenskap; Computer science; Datavetenskap;

   Sammanfattning : Today many organizations are geographically distributed, and the number of international organizations is increasing. Managing knowledge in a distributed organization may include a knowledge repository. LÄS MER

4. 3. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process

   Författare :Anne Håkansson; Andreas Hamfelt; Harald Kjellin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Artficial Intelligence; Knowledge-Based Systems; Knowledge Acquisition; Graphic Representation; Visualisation; Unified Modelling Language; Modelling Rule-based Systems; Visual programming; Declarative Programming; Information Networks; User-Centered Design; Knowledge Interface; Datavetenskap; Computer science; Datavetenskap; datalogi; Computer Science;

   Sammanfattning : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. LÄS MER

5. 4. Knowledge Technology Applications for Knowledge Management

   Författare :Kent Andersson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Informatics; computer and systems science; Constraints; Simulation; Model-Based Diagnosis; Knowledge Management; Knowledge Technology; Informatik; data- och systemvetenskap; Informatics; computer and systems science; Informatik; data- och systemvetenskap; datorteknik; Computer Systems;

   Sammanfattning : We investigate how the knowledge in knowledge technology applications for knowledge management can be represented to let the user directly manage the knowledge content of the applications.In paper I we design a representation of diagnosis knowledge that allows the user to add new components and inspect the function of the device.

7. 5. Knowledge based perceptual anchoring : grounding percepts to concepts in cognitive robots

   Författare :Marios Daoutis; Silvia Coradeschi; Amy Loutfi; Angelo Cangelosi; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; anchoring; knowledge representation; cognitive perception; symbol grounding; common-sense information; Datavetenskap; Computer and Systems Science;

   Sammanfattning : A successful articial cognitive agent needs to integrate its perception of the environment with reasoning and actuation. A key aspect of this integration is the perceptual-symbolic correspondence, which intends to give meaning to the concepts the agent refers to { known as Anchoring. However, perceptual representations alone (e.g. LÄS MER
