In the previous post, we looked at the std::is_destructible<T> type trait. Today, let us try to understand another type trait std::is_empty<T>. As per the specification, is_empty<T>::value will return true in the following cases: – The class/struct has no non-static data member – The class/struct does not define a virtual function – The class/struct does not […]
In the last article, I explained the deleted destructor in some detail. Today, I would like to talk about a related construct, a type trait called std::is_destructible. Type traits, defined in the header <type_traits>, are a big help when it comes to implementing template metaprogramming. See this article for a nice introduction to type traits in […]
Since C++ 11, we can use the keyword delete to declare functions as deleted and thus prohibit the use of these functions in the code. See this article for a brief overview. In particular, the destructor of a class/struct/union can be declared as deleted. In today’s article, I am going to discuss this specific feature in […]
The iLexicon system can handle active/passive voice conversion of fairly complex English sentences. I gave examples of the underlying verb conjugation mechanism in this article and this one. Today, I am going to give examples of the conversion of complete sentences. Here is an example of active to passive voice conversion: The above is a snapshot […]
In my earlier article, I showed how the iLexicon system can generate verb conjugations based on <Verb, Tense, Person, Number> quadruple. For the 16 tense forms discussed in that article, the verb conjugations were generated in “active” voice. We all know that “transitive” verbs can be expressed in both “active” and “passive” voice. For example, […]
After my last book review, I decided to check out a few websites that claim to simplify English text and/or help compute the measure of readability. In today’s post, I am sharing the results of my experiment. www.simplish.org This site has some interesting functionality. It does spelling check, grammar check, text simplification, and can even […]
Title: Automatic Text Simplification Author: Horacio Saggino Publisher: Morgan & Claypool Publishers Year: 2017 Automatic Text Simplification is an active area of research in NLP and has been going on for over 20 years. The idea is to transform a given text T1 into text T2 such that T2 is easier to read and understand […]
Linda, originally proposed by Nicholas Carriero and David Gelernter, is a model of process communication using a small set of well-defined primitives, operating on a tuple space. Interestingly, Sicstus Prolog comes with a library that implements Linda (both Server and Client). I played with it a little bit and really enjoyed it. In this article, I would […]
In the previous article, I showed how we can use ATNs for extracting key information from natural language text. I also pointed out in that article that Definite Clause Grammars (DCG) are a more compact formalism for doing this. That will be the focus of today’s article. For a nice introduction to DCG, read this. […]
After Wood’s paper [1], Augmented Transition Networks (ATN) became popular in the 1970s, for parsing text. An ATN is a generalized transition network with two major enhancements: Support for recursive transitions, including jumping to other ATNs Performing arbitrary actions when edges are traversed Remembering state through the use of registers See the “Further Reading” section at […]
