QLISP: A language for the interactive development of complex systems


This paper presents a functional overview of the features and capabilities of QLISP, one of the newest of the current generation of very high level languages developed for use in Artificial Intelligence (AI) research.QLISP is both a programming language and an interactive programming environment. It embeds an extended version of QA4, an earlier AI language, in INTERLISP, a widely available version of LISP with a variety of sophisticated programming aids.The language features provided by QLISP include a variety of useful data types, an associative data base for the storage and retrieval of expressions, the ability to associate property lists with arbitrary expressions, a powerful pattern matcher based on a unification algorithm, pattern-directed function invocation, "teams" of pattern invoked functions, a sophisticated mechanism for breaking a data base into contexts, generators for associative data retrieval, and easy extensibility.System features available in QLISP include a very smooth interaction with the underlying INTERLISP language, a facility for aggregating multiple pattern matches, and features for interactive control of programs.A number of applications to which QLISP has been put are briefly discussed, and some directions for future development are presented.SRI Tech.Note 120, AI Center, SRI International, Inc., Menlo Park, Calif.

Haskell: Data Analysis Made Easy Udemy


A staggering amount of data is created everyday; analyzing and organizing this enormous amount of data can be quite a complex task. Haskell is a powerful and well-designed functional programming language that is designed to work with complex data. It is trending in the field of data science as it provides a powerful platform for robust data science practices. This course will introduce the basic concepts of Haskell and move on to discuss how Haskell can be used to solve the issues by using the real-world data. The course will guide you through the installation procedure, after you have all the tools that you require in place, you will explore the basic concepts of Haskell including the functions, and the data structures.

A Simple Introduction To Data Structures: Part One – Linked Lists


The world of programming is always changing. We are constantly finding better ways to do what it is that we do. That is a great thing. Iteration is a very powerful concept. However, there are a few ideas and constructs in the computer science world that remain constant.

Scala: A Hybrid Language for Big Data


Scala is a highly scalable general purpose programming language that combines aspects of both object-oriented and functional programming. It's become increasingly important in the world of data science, rivaling more established languages like Java and Python. One of the main drivers of Scala's rise to prominence has been the explosive growth of Apache Spark (which is written in Scala), giving Scala a well-earned reputation as a powerful language for data processing, machine learning, and streaming analytics. What is Scala, and what makes it so well suited to handling big data? In this article we're going to look at what sets Scala apart as a programming language, why it's becoming increasingly important to data scientists, and what skills you should look for in a Scala developer.
