The black hole…
This is the fifth part of my ANTLR Tutorial. You can look at the previous issues here: Part I, Part II, Part III, and Part IV. For this part, we will implement arithmetic expressions and mathematical functions (in fact, only a portion, as the remaining will be left as an exercise for the reader). To […]
This is the fourth part of my ANTLR Tutorial. Previous issues, Part I, Part II and Part III are also available. Before you ask, I have no idea how many parts this tutorial will have. I will keep sharing some knowledge, both from ANTLR and C#. I hope you keep enjoying it and that it […]
Keeping up with the ANTLR tutorial, here goes a new issue. Part I and Part II are also available. As discussed previously, we are writing a conversion tool from the LOGO programming language into SVG. Up to now, we wrote a lot of code but did accomplish the generation of any SVG. In this issue […]
Continuing with the ANTLR tutorial, started in my last post, this second part advances with three main goals: Grammar Simplification The grammar presented in the last post was somewhat cucumbersome. The way we dealt with whitespace characters made the grammar difficult to read, as we needed to take care of where spaces could appear in […]
I’ve been working with Checkmarx for more than one and a half years, and I’ve been using ANTLR mostly daily. While there are some books on ANTLR, a couple of reference sites and some tutorials from the Strumenta site, I decided to write my own, with my vision of parsing and parsing writing in C#. […]
I don’t write here for some time. It’s been a busy year. But a recent event makes me feel like it is an excellent time to write a little, about the architecture I created behind the Dicionário da Língua Portuguesa [Portuguese Language Dictionary] from Academia das Ciências de Lisboa [Lisbon’s Science Academy]. The story of […]
In the last months, I’ve been giving some classes on Natural Language Processing (NLP). I decided to share some of my experiments here. I will not give you rocket science. I will cover the basics. And I will share my vision. You are warned! One of the typical tasks in NLP is to process a […]
I was playing with GloVe, and noticed it does not ship with any code to run its pipeline. I suspect there are hundred of modules to do that from withing Python, but I decided to do a quick clean script to run that from the command line, and at the same time ready to tune […]
I’ve been using eXist-DB for some time for the project of the Dicionário da Academia de Ciências de Lisboa, that is being revived from the PDF into TEI, so that a new digital version can be soon released. Recently I needed to update the server where eXist-DB was running, and decided to use a dockerized […]
I am not sure how I agreed to write a chapter for a book to be published in IGI Global. Probably, being edited by a friend that invited me personally to send a proposal made the difference. I have my contribution ready, but starting to think on just forgetting it. Why? Because IGI Global is, […]
