ALP: An Autocode List-Processing Language

Morphism: a Symbolic List Processing Language

With the formal study of natural languages, we have obtained some residual results which greatly increase our power of logical manipulation. Coupled with a computer, our language extends enormously the external logic of our computing device. This paper is concerned with a well-defined symbolic list processing language and a set of operators for this language. These operators, which we call morp...

Automation of a problem list using natural language processing

BACKGROUND The medical problem list is an important part of the electronic medical record in development in our institution. To serve the functions it is designed for, the problem list has to be as accurate and timely as possible. However, the current problem list is usually incomplete and inaccurate, and is often totally unused. To alleviate this issue, we are building an environment where the...

ALP: A programming language for reactive intelligent agents

ALP is a logic-based language for modelling intelligent behaviour in a dynamic environment. Originated in the tradition of production systems both the recognition and action phases are substantially improved. An incremental bottom-up reasoning mechanism enables the recognition of complex situations in a changing world. Situations are described in a purely declarative manner by means of a Horn c...

An Algebraic Language Processing Environment

Natural language processing: an introduction

OBJECTIVES To provide an overview and tutorial of natural language processing (NLP) and modern NLP-system design. TARGET AUDIENCE This tutorial targets the medical informatics generalist who has limited acquaintance with the principles behind NLP and/or limited knowledge of the current state of the art. SCOPE We describe the historical evolution of NLP, and summarize common NLP sub-problems...
