The amount of information in term of documents, available to users as a result of information retrieval process for the purpose of resolution of decision problems is a major factor that determines whether economically viable decisions would be made or not. Various works in the literature had addressed the challenges of representing the documents wi...
In most search systems, mapping queries with documents employs techniques such as vector space model, naïve Bayes, Bayesian theorem etc. to classify resulting documents. In this research studies, we are proposing the use of the concept of basic categories to representing the user's level of knowledge based on the concepts he employed during his sea...
The central object of this topic is Information Technology (IT). However, the concern is not to present what IT is because the addressed audience is composed of experts in IT. The presentation will focus on the exploitation of IT, developing WHY IT should be exploited and HOW in relation to entrepreneurship and wealth creation. Simple and concrete...
The development of a research, teaching, or application of competitive (economic) intelligence requires a strategic and transverse vision in regards to related issues. It is essential to integrate the role of culture when interpreting results, either from the training of a specialist or in respect to a country or region. The authors of this book, m...
An application’s conceptual model is the “mental map" that the designers employ to present information logically. A hallmark of usable design is when both the designer’s conceptual model and the end users’ conceptual models are in alignment. In this paper, we present the User and Usage Constraints in Information Systems Development as applicable to...
The final goal of Information Retrieval (IR) is knowledge production. However, it has been argued that knowledge production is not an individual effort but a collaborative effort. Collaboration in information retrieval is geared towards knowledge sharing and creation of new knowledge by users. This paper discusses Collaborative Information Retrieva...
Knowledge is attributed to human whose problem-solving behavior is subjective and complex. In today's knowledge economy, the need to manage knowledge produced by a community of actors cannot be overemphasized. This is due to the fact that actors possess some level of tacit knowledge which is generally difficult to articulate. Problem-solving requir...

It is essential to know the role of culture in order to interpret the results, either from the training of a specialist or in respect of a country or region. An expert group, supported by t...
Two popular views about the concept of information are the "information as a process" and "information as a product". While there has been much research about the two paradigms, one recurrent question has been where is the place of interpretation in information utilization? A growing trend is the concept of annotation which encourages individual in...
A fuzzy logic based Quality of Service (QoS) brokering model for e-commerce to manage system and network resources is presented in this study. This model takes into consideration limited bandwidth between clients and their Internet Service Providers; and similarly the client’s system capabilities. The QoS brokering system was modelled, developed, a...

Contrairement à d'autres pays tels que le Brésil ou la France qui ont su identifier le cercle vertueux généré par le concept de triple hélice résidant dans la mise en réseau de l'Etat, du secteur industriel et des universités, l'intelligence compétitive ne fait l'objet d'aucune politique publique dans certains pays d'Afrique tels que le Nigéria. Dè...
Information and Communication Technologies (ICT) has practically penetrated into all spheres of life. Therefore a closer look at the impact of ICT in public financial management and performance is highly justified. Public finance is defined as a field of economics concerned with paying for collective or governmental activities, and with the adminis...
Knowledge sharing has become a household name in many organizations and communities. Our concern is on how to facilitate knowledge sharing in Collaborative Information Retrieval (CIR). In CIR, there exist various types of knowledge that can be shared among users. In this paper we highlighted these knowledge and the CIR activities in which they can...
In this paper we present collaborative information retrieval (CIR) for decision making. We take Economic Intelligence (EI) as application domain and we propose an approach for managing CIR among actors in the domain. EI process has information as a central object. In EI, we consider the translation of a decision making problem to information search...
Les langages d'indexation sont des outils d'aide à la recherche d'information.

The information universe from a company point of view has changed in the last fifteen years. In fact, companies are many that are aware of the strategic information dimension. Thus, some years ago, when we talk about information management in enterprise, we talk implicitly about the documentation chain. Nowaydays, many others information approaches...
The search for information still depends on the knowledge available on the information sought and their uses. Founded on the principle of search content, the knowledge available on the information sought will result in the specification of information needs, often in the form of research equation. This principle applies regardless of the search age...
The exponential growth of multimedia information and the development of various communication media generated new problems at various levels including the rate of flow of information, problems of storage and management. The difficulty which arises is no longer the existence of information but rather the access to this information. When designing mu...
The current Information Retrieval Systems return hundreds or thousands of documents in response to a query. Users consider only the first 20 or 30, but documents are often sorted according to the query and the results are perhaps not relevant to the users’ needs. This situation is even more problematic when non expert users have difficulties in exp...

Within the framework of our studies, we regard economic intelligence as a scientific object. Thus, it is not sufficient to consider only the definitions of the concept for its comprehension. In our approach, we regard economic intelligence as a process. This process is composed of the stages of identification of a decisional problem, translation of...
The objective of most users for consulting any information database, information warehouse or the internet is to resolve one problem or the other. Available online or offline annotation tools were not conceived with the objective of assisting users in their bid to resolve a decisional problem. Apart from the objective and usage of annotation tools,...
Automatic text analysis widened the perspective of work on document contents by opening up the studies on the linguistic productions. In this case, we are using annotation as a case study. In our approach, annotation is defined as textual, graphic or sound information, attached to document source (text, photo, audio sequence or video sequence : mul...

In confusing and complex environments, the decision-maker needs
several types of information to help him in his decision-making
process. However, when the decision problem is complex and badly
defined, the decision-maker may not be able to express his
informational needs. This fact encourages us to help the
decision-maker pose the good questions, i...

The idea of personalizing the interactions of a system is not new. With stereotypes the users are grouped into classes where
all the users in a class have similar characteristics. Personalization was therefore not on individual basis but on a group
of users. Personalized systems are also used in Intelligent Tutoring Systems (ITS) and in information...
