1. 1. 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

3. 2. Towards a framework for analyzing IT strategy management in public sector : a case for IT organisations in the public sector

   Författare :Anayanci López Poveda; Paul Johannesson; Lazar Rusu; Anne Håkansson; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IT strategy management; strategic management of IT; IT service management; public sector; small medium sized IT organizations.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Small/medium sized public sector IT organisations combine several characteristics that difficult the effective use of an IT strategy. Research has reported small/medium sized organisations as using unstructured and informal IT management initiatives, which frequently leads to inexistent or incipient use of IT strategy. LÄS MER

4. 3. Integrating Security in Software Engineering Process: The CSEP Methodology

   Författare :Esmiralda Moradian; Anne Håkansson; Bengt Carlsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In today’s organizations, a vast amount of existing software systems is insecure, which results in compromised valuable assets and has negative consequences on the organizations. Throughout the years, many attempts have been made to build secure software systems, but the solutions proposed were limited to a few add-on fixes made after implementation and installation of the system.

7. 5. Context Knowledge Base for Ontology Integration

   Författare :Dan Wu; Anne Håkansson; Carl-Gustaf Jansson; Jelena Zdravkovic; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ontology integration; semantic and pragmatic integration; context; knowledge base; rules; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Ontology integration is a process of matching and merging two ontologies for reasons such as for generating a new ontology, thus creating digital services and products. Current techniques for ontology integration, used for information and knowledge integration, are not powerful enough to handle the semantic and pragmatic heterogeneities. LÄS MER
