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)
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)
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)
Exploratory search systems help users learn or investigate a topic. The richness of the linked open data can be used to assist this task. We present a method that selects and ranks linked data resources that are semantically related to the user's interest. The objective is to focus the user's attention on a meaningful subset of highly informative resources.(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)
Despite the widespread use of Web 2.0 techniques in our entire surrounding environment, which tend to make it more social, more dynamic and driven by users, some domains have not really changed yet. This is the case for (e-)books which reading remains mainly a solitary activity - or which is done at least without appropriate collaborative tools. However,(More)
