TLDR
Object-based knowledge representation systems are systems expressly designed for representing knowledge in the form of objects and classes and are better suited for providing representation services for knowledge-based systems than are object-oriented programming systems.About:

Terminological Representation, Natural Language & Relation Algebra
TL;DR: This paper establishes a link between Kl-one-based knowledge representation concerned with terminological representation and the work of P. Suppes and M. Bottner in computational linguistics and shows how this link can be utilised for the problem of finding adequate terminological representations for given information formulated in ordinary English.

TL;DR: MRI provides the best tools for definition ofLDHIV syndrome and reveals variable phenotypes among LDHIV patients, suggesting a novel split phenotype among LDhIV patients of either dorsocervical or intra-abdominal fat accumulation.
Journal ArticleDOI
A description logic approach for representing engineering design standards
TL;DR: How description logic can be used to represent the knowledge contained in engineering design standards is discussed and examples of the LRFD and UBC codes modeled in description logic are given to demonstrate the power of description logic languages as representational tools for engineering knowledge in general and design standards in particular.

Introducing Knowledge Representation Techniques in Database Models
TL;DR: The main point is to introduce the concept of defined class, i.e., class whose structural description gives necessary and sufficient conditions for an object to belong to it.

A mathematical introduction to logic
TL;DR: A comparison of first- and second-order logic in the case of SETs shows that the former is more likely to be correct and the latter is less likely.

An overview of the KL-ONE Knowledge Representation System
TL;DR: KL-ONE as mentioned in this paper is a system for representing knowledge in Artificial Intelligence programs and has been used in both basic research and implemented knowledge-based systems in a number of places in the AI community.

A logic of implicit and explicit belief
TL;DR: This paper point out deficiencies in current semantic treatments of knowledge and belief and suggest a new analysis in the form of a logic that avoids these shortcomings and is also more viable computationally.

TL;DR: This specification presents adescription of the standard Programmer Interface for the Common Lisp Object System, a object-oriented extension to Common Lisp as defined in Common Lisp: The Language, and provides a facility for declaring new types of method combination.

Krypton: A Functional Approach to Knowledge Representation
TL;DR: The authors have developed a design strategy for avoiding these types of problems and have implemented a representation system based on it, called Krypton, which clearly distinguishes between definitional and factual information.
