The purpose of this paper is to show that future prices do not have to be known to make successful investments and that anticipating movements (increases or decreases) of the price can be sufficient. Probabilistic classification systems based on pattern recognition theory appear to be a good way to reach this objective. Moreover, they include some other advantages, principally in terms of risk management. Results show satisfactory classification hit rates but a rather poor translation into financial gains. This paper tries to identify causes of this problem and proposes some ideas of solution.

Marketing Information and Knowledge in Boutique Hotels: A Qualitative Study

The International Journal of Knowledge, Culture, and Change Management: Annual Review, 2011

The popularity of boutique hotels brings more intense competition to the hospitality industry in ... more The popularity of boutique hotels brings more intense competition to the hospitality industry in Chiang Mai, Thailand. The entrepreneurial hotel owners, who are mostly architects, introduced the unique designs, personalized accommodation and service facilities to differentiate themselves from conventional hotels, resorts and guesthouses. However, these entrepreneurs often lack a background of business and marketing, so they need to augment their marketing strategy in order to survive in an over-supply market. The success ...

In this work we describe how we will try to extend an authoring tool (Sephyr/Phoenix) in order to facilitate the reusability of learning objects. This tool previously forecasted for building a conceptual segmentation, will be connected to a learning object repository (Ariadne Knowledge Pool), and combined with an automated LOM generator, it will allow the creation or the re-composition, based on a conceptual ...

Strategic Alignment and IT Project Portfolio Management

With this holistic perspective in mind, we redesigned the dysfunctioning IT project portfolio management process of one of the FTSE 100 global companies. The new process aims at better identifying, evaluating and balancing projects in the light of business strategy. A complementary knowledge management system was conceived to achieve adequate integration of business processes and human capital. Linked together, they enable appropriate alignment between corporate business strategy, IT strategy and operations. We developed and implemented a support system showing the distribution of the projects according to retained performance indicators. The results obtained are well in line with the decision makers' needs and well tuned to their business strategy. To fully leverage the benefits of this approach, this framework should be extended to the complete organizational process.

An engine for performing numerical analysis is integrated with the knowledge-based systems, allowing a dynamic, computer-guided analysis. The user interactively defines the domain, problem and goal, while the software progressively refines the task using feedback, questions and data analysis. This process, while not requiring knowledge of neural networks, can help the user build a successful neural network application.

Phoenix tool: a support to semantic learning model

We noticed that the learning object enriched by its Metadata is not sufficient for an easy reuse and most of the time their granularity is not enough thin. We try in this paper to insist on the importance of the context as well as the granularity for a best reuse. We will present a Semantic Learning Model (SLM) facilitating the reusability of learning objects according to a pedagogical context. Our main contribution in this paper is the explanation of the decomposition process of pedagogical entities using an authoring tool called PHOENIX.

On the same way the federation of Learning Object Repositories could conduct to the same difficulty while wanting to obtain a critical mass of learning object in order to facilitate their reusability. In this paper we describe a model, called SLM model and present a tool facilitating the decomposition process and the creation of multi source documents. ...

Towards a semantic learning model fostering learning object reusability

First of all, we present four key criteria for an efficient authoring tool: adaptive level of granularity, flexibility, integration and interoperability. Secondly, we introduce and describe our six-level Semantic Learning Model (SLM) designed to facilitate multi-level reuse of learning materials and search by defining a multi-layer model for metadata. Finally, after mapping different learning content models ...
