Automatically building concept structures and displaying concept trails for the use in brainstorming sessions and content management systems

The automated creation and the visualization of concept structures become more important as the number of relevant information continues to grow dramatically. Especially information and knowledge intensive tasks are relying heavily on accessing the relevant information or knowledge at the right time. Moreover the capturing of relevant facts and good ideas should be focused on as early as possible in the knowledge creation process. In this paper we introduce a technology to support knowledge structuring processes already at the time of their creation by building up concept structures in real time. Our focus was set on the design of a minimal invasive system, which ideally requires no human interaction and thus gives the maximum freedom to the participants of a knowledge creation or exchange processes. The initial prototype concentrates on the capturing of spoken language to support meetings of human experts, but can be easily adapted for the use in Internet communities that have to rely on knowledge exchange using electronic communication channels.

Real-Time generation of topic maps from speech streams

Topic Maps are means for representing sophisticated, conceptual indexes of any information collection for the purpose of semantic information integration. To properly fulfil this purpose, the generation of Topic Maps has to base on a solid theory. This paper proposes the Observation Principle as the theoretical fundament of a future scientific discipline Topic Maps Engineering. SemanticTalk generates sophisticated, conceptual indexes of speech streams in real-time. Reflecting the Observation Principle, this paper describes how these indexes are created, how they are represented as Topic Maps and how they can be used for semantic information integration purposes.

Generating semantic contexts from spoken conversation in meetings

SemanticTalk is a tool for supporting face-to-face meetings and discussions by automatically generating a semantic context from spoken conversations. We use speech recognition and topic extraction from a large terminological database to create a network of discussion topics in real-time. This network includes concepts explicitly addressed in the discussion as well as semantically associated terms, and is visualized to increase conversational awareness and creativity in the group.

SemanticTalk: software for visualizing brainstorming sessions and thematic concept trails on document collections

In this demonstration we introduce a technology to support knowledge structuring processes already at the time of their creation by building up concept structures in real time. Our focus was set on the design of a minimal invasive system, which ideally requires no human interaction and thus gives the maximum freedom to the participants of a knowledge creation or exchange processes. The system captures and displays spoken dialogs as well as text documents for further use in knowledge engineers tools.

Using digital communication structures to support knowledge management

IT-based knowledge management is often considered under the aspect of information storage and retrieval only. Although the theory of organizational knowledge management reflects on the description of communication structures and communication events between partners, the support of the users by information technology systems does not meet the expectations at all. This contribution describes an approach and a software implementation that uses digital communication structures, which result from the use of new forms of communication infrastructures, to facilitate an easier access to relevant information that can be qualified by identification with the knowledge creator.

Prozessorientiertes Wissens management durch kontextualisierte Informationsversorgung aus Geschäftsprozessen

Die bedarfsgerechte Bereitstellung von Informationen ist ein wesentlicher Bestandteil des IT-gestutzten Wissens managements. Wahrend solche Informationsrechercheprozesse in der Vergangenheit oft als eigenstandige Problemklasse aufgefasst wurden, versuchen neuere Ansatze das situative Informationsbedurfnis der Benutzer zu berucksichtigen. Dieser Beitrag zeigt unter Bezug auf das laufende Forschungsprojekt PreBIS auf, wie unter Berucksichtigung wertschopfender Geschaftsprozesse im Unternehmen Kontextinformationen automatisch fur die Informationsbereitstellung abgeleitet werden konnen und wie dieser, als Kontextualisierung bezeichnete Bereitstellungsprozess verallgemeinert werden kann.

KnowBiT: knowledge management in the biotechnology industry

Due to the scarce supply in personnel, the immanent significance of knowledge and the need for company-spanning cooperation, much is demanded from knowledge management solutions in the biotechnology industry. Together with a biotechnology company, an application-oriented solution was developed within the scope of the KnowBiT project to meet these requirements. The main emphasis was put on knowledge inquiry and knowledge transfer without the need to adapt the existing knowledge intensive processes. Thereby, the integrated application of new communication infrastructures was used to facilitate the access to information and to qualify it by identifying it with knowledge carriers or domain experts.
