How do you define a metamodel?

Definition. A metamodel is a model that consists of statements about models. Hence, a metamodel is also a model but its universe of discourse is a set of models, namely those models that are of interest to the creator of the metamodel.

Which model is know as a meta-model?

The Spiral model is called a Meta-Model because it subsumes all the other SDLC models. The spiral model uses the approach of the Prototyping Model by building a prototype at the start of each phase as a risk-handling technique.

What is meta-model in object oriented analysis and design?

A meta-model defines concepts and their relationships thanks to a class diagram. A meta-model only defines structure (no semantic). A model is an instance of a meta-model if it respects the structure defined by the meta-model. The UML meta-model defines the structure that all UML models must have.

What is a meta-model is understanding a meta-model important?

A metamodel is a representation (a model) of a modeling language; it formalizes the aspects and the concepts used by a modeling language, and models the domain in question. Learn more in: Models Oriented Approach for Developing Railway Safety-Critical Systems with UML.

What is a metamodel used for?

A metamodel or surrogate model is a model of a model, and metamodeling is the process of generating such metamodels. Thus metamodeling or meta-modeling is the analysis, construction and development of the frames, rules, constraints, models and theories applicable and useful for modeling a predefined class of problems.

What is the meta-model used for?

The meta-model in Neuro-linguistic programming (or meta-model of therapy) is a heuristic set of questions designed to specify information, challenge and expand the limits to a person’s model of the world. It responds to the distortions, generalizations, and deletions in the speaker’s language.

What is meta-model in machine learning?

Meta-learning in machine learning refers to learning algorithms that learn from other learning algorithms. Most commonly, this means the use of machine learning algorithms that learn how to best combine the predictions from other machine learning algorithms in the field of ensemble learning.

Why do we need meta models?

Common uses for metamodels are: As a schema for semantic data that needs to be exchanged or stored. As a language that supports a particular method or process. As a language to express additional semantics of existing information.

What is the meaning of the term metamodeling?

Metamodeling. Thus metamodeling or meta-modeling is the analysis, construction and development of the frames, rules, constraints, models and theories applicable and useful for modeling a predefined class of problems. As its name implies, this concept applies the notions of meta- and modeling in software engineering and systems engineering.

Which is the best description of a metamodel?

Various types of metamodels include polynomial equations, neural network, Kriging, etc. “Metamodeling” is the construction of a collection of “concepts” (things, terms, etc.) within a certain domain.

How is metamodeling used in the Semantic Web?

Dean Allemang, Jim Hendler, in Semantic Web for the Working Ontologist (Second Edition), 2011 Metamodeling is the name commonly given to the practice of using a model to describe another model as an instance. One feature of metamodeling is that it must be possible to assign properties to classes in the model.

Which is an example of a metamodeling language?

QVT is based on the meta-object facility (MOF). Among many other model transformation languages (MTLs), some examples of implementations of this standard are AndroMDA, VIATRA, Tefkat, MT, ManyDesigns Portofino . Meta-models are closely related to ontologies.

How do you define a metamodel? Definition. A metamodel is a model that consists of statements about models. Hence, a metamodel is also a model but its universe of discourse is a set of models, namely those models that are of interest to the creator of the metamodel. Which model is know as a meta-model?…
