    A partial order and partial reliable connection (POC) is an end-to-end transport connection authorized to deliver objects in an order that can differ from the transmitted one. The service that this connection provides is also authorized to lose a number of objects. The POC approach establishes a conceptual link between both connectionless best-effort (CL) and connection oriented (OC) protocols. Th... View full abstract»

    The paper discusses the interface needs for the emergence of new authoring tools for the creation of multimedia documents. We think that it is possible to break down the specify-and-run process of most existing tools to have more direct editing functions close to a “wysiwyg” approach. After identifying the requirements of direct editing for multimedia documents, we describe an authorin... View full abstract»

    A growing amount of tasks are expected to be delegated to software agents by human users. Such agents carry personal data of the user and act on his behalf. If mobile software agents leave the users' host, the users are left with an uncomfortable lack of knowledge about and control over “what's going on”. The authors believe that an important remedy for this lies in sophisticated visua... View full abstract»

    Multimedia documents are different from traditional text documents, because they may contain encodings of raw sensorical data. This fact has severe consequences for the efficient indexing and retrieval of information from documents in large unstructured collections (e.g. WWW), because it is very difficult to automatically identify generic meanings from visual or audible objects. A novel method for... View full abstract»
