A fuzzy database and knowledge base environment for intelligent retrieval

We discuss an environment that permits flexible modeling and fuzzy querying of complex data and knowledge including uncertainty. With such an environment, one can have intelligent retrieval of information from knowledge- intensive applications. In this study, we specifically describe the details (the model, inference mechanism, etc,) of the fuzzy knowledge base system (coupled with a fuzzy object-oriented database system, namely FOOD) of this environment.

Transformation of conceptual models to executable High Level Architecture federation models
Özhan, Gürkan; Oğuztüzün, Mehmet Halit S. (Springer, 2015-01-01)
In this chapter, we present a formal, declarative, and visual model transformation methodology to map a domain conceptual model (CM) to a distributed simulation architecture model (DSAM). The approach adheres to the principles of model-driven engineering (MDE). A two-phased automatic transformation strategy is delineated to translate a field artillery conceptual model (ACM) into a high-level architecture (HLA) federation architecture model (FAM). The produced model is then compiled by the code generator to ...
Flexible querying in an intelligent object-oriented database environment
Koyuncu, M; Yazıcı, Adnan; George, R (2000-10-28)
Many new-generation database applications demand intelligent information management necessitating efficient interactions between database gr. knowledge bases and the users. In this study we discuss evaluation of imprecise queries in an intelligent object-oriented database environment, IFOOD. A flexible query evaluation mechanism, capable of handling different data types including complex and imprecise data and knowledge is presented and key language issues are addressed.
A logic programming framework for modeling temporal objects
Çiçekli, Fehime Nihan; Sergot, M (1996-10-01)
We present a general approach for modeling temporal aspects of objects in a logic programming framework. Change is formulated in the context of a database which stores explicitly a record of all changes that have occurred to objects and thus (implicitly) all states of objects in the database. A snapshot of the database at any given time is an object-oriented database, in the sense that it supports an object-based data model. An object is viewed as a collection of simple atomic formulas, with support for an ...
A computer-supported methodology for requirements modelling in CIM for small and medium size enterprises: A demonstration in Apparel Industry
Hashemipour, M; Anlagan, O; Kayaligil, S (1997-01-01)
This paper discusses the first phase of a computer-assisted methodology for implementing CIM within small and medium enterprises. Some of the existing methodologies and tools were furnished by extra items to ease the process for small and medium size manufacturing companies. The methodology aims at using limited expertise, limited staff, and minimising cost. The existing analysis tools (i.e. DFDs, ELH, and tools in the GRAI methodology) were modified and a new tool was developed (PIFR) to shed light on the ...
A fuzzy deductive object-oriented database model
Bostan, B; Yazıcı, Adnan (1998-05-09)
Object-oriented and deductive database models are two different paradigms in database modeling. As has been pointed out by many researchers, [1], [6], [14], each of these data models has its shortcomings when dealing with database/knowledge-base applications. Therefore, it is believed that combining object-oriented concepts with those of deductive database modeling results in a powerful data model especially for knowledge-intensive applications. In these applications, it is important to model and manipulate...
