This article is a preliminary survey of some methods, techniques and tools aimed at managing corporate knowledge from a corporate memory (CM) designer's perspective. In particular, it analyzes problems and solutions related to the following steps: detection of needs of CM, construction of the CM, its diffusion (specially using the Internet technologies),(More)
Personalised multimedia access aims at enhancing the retrieval process by complementing explicit user requests with implicit user preferences. We propose and discuss the benefits of the introduction of ontologies for an enhanced representation of the relevant knowledge about the user, the context, and the domain of discourse, as a means to enable(More)
A personalised system is a complex piece of software made of many interacting parts, from data ingestion to presenting the results to the users. A plethora of methods, tools, algorithms and approaches exist for each piece of such a system: many data and metadata processing methods, many user models, many filtering techniques, many accuracy metrics, many(More)
In the real world, relationships between objects (for example, dependencies among them) play an important role. Therefore, knowledge representation formalism should offer powerful enough capabilities to represent them. In this paper, we aim to represent complex relations among all kinds of concepts, and to express the dynamic behaviour associated to such(More)
Many visualization systems have been designed and developed to address the ever-growing mass of temporal data. The multiple aspects of time (linear vs cyclic, instant vs interval, different units etc.) have been represented in different manners in existing visualization systems. A design space is thus needed to analyse and compare different visual(More)
This paper supports the Discovery Hub demonstration proposal. Web growth, both in size and diversity, and users' growing expectations increase the need for innovative search approaches and technologies. Exploratory search systems are built specifically to help user in cognitive consuming search tasks like learning or investigation. Some of these systems are(More)
In Concurrent Engineering, several participants (designers, managers,...) stemming from different specialities, collaborate in order to build a system. In this paper, we propose a representation with the Conceptual Graph formalism to keep a trace of the design process in Concurrent Engineering as a project memory. Such design process is a cycle of(More)
