La subjectivité des estimations et des perceptions, la complexité de l’environnement, l’interaction entre sous-systèmes, le manque de données précises, les données manquantes, une faible capacité de traitement de l’information, et l’ambiguïté du langage naturel représentent les principales formes d’incertitude auxquelles les décideurs doivent faire face lorsqu’ils prennent des décisions stratégiques à l’aide de systèmes d’intelligence économique. Cette étude utilise un paradigme de « soft computing » pour identifier et analyser l’incertitude, que nous associons à la notion de facteurs de risque d’information. Pour cela, nous proposons un modèle de rapprochement exploitant des ontologies, ainsi qu’un modèle baptisé « FuzzyWatch » fondé sur la logique floue. Nous avons modélisé le processus de prise de décision depuis la définition du problème jusqu’à la réponse à la question : « est-il raisonnable de décider ? ». Un diagramme causal d’Ishikawa permet de prendre en compte les facteurs intangibles dans cette approche. Le cadre de référence du rapprochement de connaissances a été prévu pour faciliter le partage et la réutilisation de connaissances entre les utilisateurs et la machine. En complément, les facteurs intangibles, les émotions, les ambiguïtés du langage naturel sont pris en compte à l’aide de fonctions d’appartenance floues. Les outils de la logique floue ont été également utilisés au niveau des ontologies (« FuzzOntology »). Au niveau du processus de recherche d’information, l’introduction d’une fonction de mise en correspondance floue, appelée « FuzzyMatch », améliore le taux de rappel et subséquemment le processus d’intelligence économique. Le modèle « Fuzzontologique » autorise une prise en compte flexible de facteurs intangibles et incertains, offrant ainsi un moyen de traiter l’ambiguïté du langage naturel. FuzzyMatch permet de réduire les problèmes de données manquantes. A l’aide de ces modèles, le processus de décision en intelligence économique bénéficie d’une réduction des risques liés à l’information lors du processus de recherche.

Subjective estimation and perception, complexity of the environment under study, interaction amongst subsystems, lack of precise data, missing data, limited information processing capacity and ambiguity in natural languages are major forms of uncertainty facing Decision Makers in the process of delivering strategic decisions in economic intelligent systems. This study employs soft computing paradigm to capture and analyze uncertainty based on information risk factors via our proposed knowledge reconciliation model based on ontology and the FuzzyWatch model. We modeled the process of decision making from the point of problem definition to decision delivery (translation credibility) and include intangible factors with the fish-bone architecture. Ontological framework for Knowledge Reconciliation was developed to facilitate knowledge sharing and reuse among both human and computer agents while intangible factors, emotions and ambiguities in natural languages were captured with fuzzy membership function. We extended this operation with fuzzy that is – what ontology captures is interpreted by fuzzy techniques (FuzzOntology). The fuzzy match relation for information retrieval tagged “FuzzyWatch” improves the information search result thus reducing the risk of missing data which is of grave consequence in Economic Intelligence process. FuzzOntological model facilitates a flexible means of capturing intangible and uncertain factors as a means of resolving the ambiguity in natural languages. FuzzyWatch assists in reducing missing data problems. Future decisional process will contend with lesser information retrieval risks in Economic Intelligence process using this model.

ACKNOWLEDGEMENT
To my supervisors both home and abroad Professor (Mrs.) Odile Thiery and Professor
(Mrs.) Adenike Oyinlola Osofisan, I am very grateful. Their candid encouragement,
patience and the pain in reading over and over this work is note worthy.

To the duo of Professor Samuel Ajila (Carleton University, Ottawa, Cananda) and Eric
Boutin (Universite du sud Toulon var, France) for accepting to read through and serve as
external examiners during the defence of this work, thank you for your laudable
comments.

I equally want to extend sincere appreciation to Professor Amos Abayomi David who
took it upon himself to give the opportunity to me. His doggedness and resilience, words
of wisdom and encouragement, readiness to serve, listen and advice is very uncommon.
Thank you very much sir. His households are very wonderful; I cannot forget the
scintillating meal of “Mrs. Prof”.

The contributions of colleagues and friends at SITE LORIA, France are well appreciated.
First and foremost, to my friend and co-supervisor Gerald Duffing, who assisted
tremendously in the success of this work. Sincere greetings go to Victor Omoyibo of
France, Y’aman, Bros SOJ, Baba, Hannen, Chedia, Pierre, and Stefan who on many
occasions assisted in French translation.

To the French government ambassador to Nigeria that facilitates the scholarship for this
work. To the manager of foreign students both CNOUS and CROUS and wonderful
people like Rojo, Jeanick and Benedict, thank you very much.

To my sister and friend, whom I closely got acquainted with in the last lap of the
program, Rudzz Rakotomalala surnamed Abake. Her supports, endearing words makes
me feel at home in France, how I wish I could turn back the hands of time? Regard to her
daughter Miangaly (Miangy).

To my students and colleagues at the University of Ibadan, particularly my soul mate
Olumide Longe, Junbor, Dokita Robert, Dr. Akinkunmi, Alake Daramola and others too
numerous to mention, thank you.

To all my family members, holding the forth while am not at home, prayerfully
supporting me in this work, I am greatly indebted to you all. I really love and appreciate
you. Thanks for being there. Abraham-Marian Onifade dynasty shall enlarge in grace.

And to Him, Eternal, who has made ALL things beautiful in His time, Merci Seigneur
