Decision modelA decision model in decision theory is the starting point for a decision method within a formal (axiomatic) system. Decision models contain at least one action axiom. An action is in the form "IF is true, THEN do ". An action axiom tests a condition (antecedent) and, if the condition has been met, then (consequent) it suggests (mandates) an action: from knowledge to action. A decision model may also be a network of connected decisions, information and knowledge that represents a decision-making approach that can be used repeatedly (such as one developed using the Decision Model and Notation standard).
GeovisualizationGeovisualization or geovisualisation (short for geographic visualization), also known as cartographic visualization, refers to a set of tools and techniques supporting the analysis of geospatial data through the use of interactive visualization. Like the related fields of scientific visualization and information visualization geovisualization emphasizes knowledge construction over knowledge storage or information transmission.
Decision analysisDecision analysis (DA) is the discipline comprising the philosophy, methodology, and professional practice necessary to address important decisions in a formal manner. Decision analysis includes many procedures, methods, and tools for identifying, clearly representing, and formally assessing important aspects of a decision; for prescribing a recommended course of action by applying the maximum expected-utility axiom to a well-formed representation of the decision; and for translating the formal representation of a decision and its corresponding recommendation into insight for the decision maker, and other corporate and non-corporate stakeholders.
Interaction techniqueAn interaction technique, user interface technique or input technique is a combination of hardware and software elements that provides a way for computer users to accomplish a single task. For example, one can go back to the previously visited page on a Web browser by either clicking a button, pressing a key, performing a mouse gesture or uttering a speech command. It is a widely used term in human-computer interaction. In particular, the term "new interaction technique" is frequently used to introduce a novel user interface design idea.
Decision intelligenceDecision intelligence is an engineering discipline that augments data science with theory from social science, decision theory, and managerial science. Its application provides a framework for best practices in organizational decision-making and processes for applying machine learning at scale. The basic idea is that decisions are based on our understanding of how actions lead to outcomes. Decision intelligence is a discipline for analyzing this chain of cause and effect, and decision modeling is a visual language for representing these chains.
Management du système d'informationLe management du système d'information ou la gestion des systèmes d'information (aussi appelé dans un sens plus restreint : informatique de gestion et parfois management de la performance) est une discipline des sciences de gestion ou du management regroupant l'ensemble des connaissances, des techniques et des outils assurant la gestion de données et leur sécurité, et plus généralement l'organisation et la protection du système d'information.
Abstraction (informatique)En informatique, le concept d'abstraction identifie et regroupe des caractéristiques et traitements communs applicables à des entités ou concepts variés ; une représentation abstraite commune de tels objets permet d'en simplifier et d'en unifier la manipulation. thumb|upright=1.4|Différentes couches de logiciel, partant d'en bas, le matériel est programmé en langage binaire, via un firmware, qui permet une abstraction pour le noyau, puis lui même pour le système d'exploitation, qui a son tour permet une abstraction pour les applications.
User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.

L'interaction Homme-machine (ou interaction humain-machine), appelée IHM, s’intéresse à la conception et au développement de systèmes interactifs en prenant en compte ses impacts sociétaux et éthiques. Les humains interagissent avec les ordinateurs qui les entourent et cette interaction nécessite des interfaces qui facilitent la communication entre l'humain et la machine.
Arbre de décision (apprentissage)L’apprentissage par arbre de décision désigne une méthode basée sur l'utilisation d'un arbre de décision comme modèle prédictif. On l'utilise notamment en fouille de données et en apprentissage automatique. Dans ces structures d'arbre, les feuilles représentent les valeurs de la variable-cible et les embranchements correspondent à des combinaisons de variables d'entrée qui mènent à ces valeurs. En analyse de décision, un arbre de décision peut être utilisé pour représenter de manière explicite les décisions réalisées et les processus qui les amènent.
