Modeling Grammars: a New Perspective on an Old Problem
نویسندگان
چکیده
A core activity in information systems development involves understanding the conceptual model of the domain that the information system supports. Any conceptual model is ultimately created using a conceptual-modeling (CM) grammar. Accordingly, just as high quality conceptual models facilitate high quality systems development, high quality CM grammars facilitate high quality conceptual modeling. This paper seeks to provide a new perspective on improving the quality of CM grammar semantics. For the past twenty years, the leading approach to this topic has drawn on ontological theory. However, the ontological approach captures just half of the story. It needs to be coupled with a logical approach. We show how ontological quality and logical quality interrelate and we outline three contributions of a logical approach: the ability to see familiar conceptual-modeling problems in simpler ways, the illumination of new problems, and the ability to prove the benefit of modifying CM grammars.

متن کاملProcedural Modeling as an Analytical Tool for 3D Survey in Urban Design Assessment
This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...
متن کاملModeling Perspective Using Adaptor Grammars
Strong indications of perspective can often come from collocations of arbitrary length; for example, someone writing get the government out of my X is typically expressing a conservative rather than progressive viewpoint. However, going beyond unigram or bigram features in perspective classification gives rise to problems of data sparsity. We address this problem using nonparametric Bayesian mo...
متن کاملGenGraph: A Multi-Grammar and Multi-Perspective Business Modeling Tool - Overview of Conceptualization and Implementation
Within the information systems field, modeling of business systems results in complex information models which demand appropriate tool support. This paper discusses the motivation and development of a generic editor for information modeling. Our approach enables the user to configure the concepts of the utilized modeling grammars. So, this approach does not implement a specific set of modeling ...
متن کاملModeling and assessment of new urbanist principles in center neighborhoods in Kashan
The most important problem of the worn- ut context in urban is that these textures can not meet the needs of contemporary life. This can be of tissue due to the specific characteristics of a rare opportunity to play an effective role in sustainable development, one of the main strategies in this area can be a new urbanism approach. The aim of this study is to evaluate the principles of new urba...
