Construction Informatics issues in engineering, computer science, and ontology

چکیده
Civil engineers operate with such notions as tree–structured cost frames and graph–structured project plans. We show how a cost frame denotes a possibly infinite set of project plans and, vice–versa, how a project plan denotes a possibly infinite set of cost frames. The civil engineer, we claim, operates freely in a domain where cost frames determine project plans, namely the project plans which can be executed within the financial restrictions defined by the given cost frame, and vice– versa. In this paper, we model this two–way connection and show that it forms a Galois connection. We thus believe that our contribution, in its mathematics, captures an everyday concern of civil engineers in planning, management, and control of building projects. 66 Models of two civil engineering concepts and their Galois connection

Centralized Clustering Method To Increase Accuracy In Ontology Matching Systems
Ontology is the main infrastructure of the Semantic Web which provides facilities for integration, searching and sharing of information on the web. Development of ontologies as the basis of semantic web and their heterogeneities have led to the existence of ontology matching. By emerging large-scale ontologies in real domain, the ontology matching systems faced with some problem like memory con...
متن کاملOntological Engineering from the Informatics Perspective
In this report we present an introductory overview of ontological engineering from the informatics (computer science) perspective. The term “ontology” is inherited from philosophy,in which it is a branch of metaphysics concerned with the nature of being. Ontologies are knowledge management and representation techniques that can be analyzed theoretically using concepts from description logic for...
متن کاملFuzzy Domain Ontology Discovery for Business Knowledge Management
Ontology plays an essential role in the formalization of business information (e.g., products, services, relationships of businesses) for effective human-computer interactions. However, engineering of domain ontologies turns out to be very labor intensive and time consuming. Recently, some machine learning methods have been proposed for automatic discovery of domain ontologies. Nevertheless, th...
متن کاملAn Extension of an Environment for Building/using Ontologies "hozo" toward Practical Ontology Engineering
Through the spread of ontological engineering, many technologies and software tool for ontology construction were developed. By using them, many ontologies have been constructed in various domains. On these backgrounds, we have been developing an ontology engineering environment “Hozo” and using the tool to construct a lot of ontologies in various domains such as medical science, bioinformatics...
متن کاملAnalysis of Flow of Nanofluid through a Porous Channel with Expanding or Contracting Walls using Chebychev Spectral Collocation Method
In this work, we applied Chebychev spectral collocation method to analyze the unsteady two-dimensional flow of nanofluid in a porous channel through expanding or contracting walls with large injection or suction. The solutions are used to study the effects of various parameters on the flow of the nanofluid in the porous channel. From the analysis, It was established that increase in expansion r...
