Title: Functional Programming in C++: How to improve your C++ programs using functional techniques Author: Ivan Cukic Publisher: Manning Publications Co. Year: 2019 This book came out recently, about a week ago. I bought it immediately, and when I started to read it, I couldn’t put it down! Very informative and well written. If you […]
In my previous post I gave examples of modeling homeopathy remedies using Flora-2. Today I want to show an example from a completely different domain namely, Acupuncture. Acupuncture is an ancient system of Chinese medicine and is practised in many countries. It is based on the principle that our body has several meridians, which are pathways for […]
The idea of encountering different worlds with varying truths is an interesting one. It has deep connections to philosophy and logic. For a nice discussion, see this article. Today, we are going to take advantage of Flora-2‘s module system to simulate possible worlds. Flora-2 allows us to dynamically associate any knowledge base (KB) with any […]
In my last post, I got started with Flora-2 and showed how we can model homeopathic remedies from a therapeutics perspective. Although such a limited view of remedies can be helpful in treating acute ailments, for treating chronic diseases, a comprehensive understanding of the various remedies from the perspective of keynotes, kingdom classification and miasms […]
I am always on the lookout for a good Knowledge Representation (KR) system that facilitates modeling and reasoning about real-world knowledge. I have experience with KnowledgeWorks available in LispWorks since I have used it in a few projects. I have also taken a cursory look at PowerLoom and Racer. Last week, I came across Flora-2 and its commercial counterpart ErgoAI from […]
Calling a function (or function object) dynamically, through a pointer known at runtime, is a common programming scenario. Almost all languages support this use case. Lisp, for example, has apply and funcall. When using apply, you can see that the arguments are passed via a separate list object. With funcall, however, the arguments are passed […]
In the last post, I outlined an approach to convert a dependency graph (the result of dependency parsing) to RDF. The particular RDF format I used is Turtle, which is widely supported. Today, I would like to show how to load this RDF data in a Semantic Graph database and make queries on it. There […]
Dependency parsing is widely used these days, and many NLP tools give a dependency graph as the parsed representation of the input text. See for example, SpacY and TextRazor. The following is the dependency tree corresponding to the sentence Mary is drinking cold water: The above tree was generated using SpacY. You can see that […]
Recently I came across a nice Lisp-based Monadic Parser Combinator library written by Massung. Unlike the traditional parser generators such as ANTLR, this library allows us to embed the parser in Lisp. Similar libraries are available for other languages too (see, for example ParsecJ for Java). The original idea of Monadic parser is from Haskell’s Parsec […]
In my previous post, I showed how to build a C-based Windows DLL to execute Prolog predicates in the Sicstus Prolog engine. Today, I want to show how to build an executable (on Windows) from a C/C++ program that uses Sicstus prolog engine. The process is quite simple. In order to make things interesting, I am […]
