The use of language for communication purposes introduces a semantic gap in data processing. We have developed a new tool called semantic distance to overcome this gap. A previous presentation of our tool was based on an empirical approach. Here, we examine the properties and theoretical foundation of semantic distance from a rationalistic perspective. We present an epistemological framework to explain the meaning of semantic distance. As a tool, the purpose of semantic distance is the exchange of data or knowledge based on linguistic expressions between software components. We propose a review of the relationship between language and its representation for data processing based on the underlying philosophical assumptions. Description logic is a new paradigm in the medical informatics community to express relations between terms in "is-a" hierarchies. The utility of semantic distance is compared to description logic for communication purposes in different use cases.
Beyond to be in fashion, the knowledge management (KM) is by itself a powerful strategic weapon for managing organizations. In a first part, the authors analyze strategic concepts related to management, emphasizing the attachment between KM and competitive advantage. Finally, the authors tie the KM to learning process ("tacit knowledge", "socialization", "externalization", "combination", and "internationalization").
