sparqlprog is a programming language and environment that can be used to write composable modular building blocks that can be executed as federated SPARQL queries. Example of use (command line): pl2sparql -u sparqlprog/ontologies/ebi -u sparqlprog/ontologies/faldo -s ebi "\ protein_coding_gene...
Dennis Merritt is finally retiring! See what he's up to at:denniscmerritt.com His books, "Adventure in Prolog" and "Building Expert Systems in Prolog" are available from Amazon. Amzi! Prolog + Logic Server is open source at:github.com/AmziLS ...
which have been taken to similar situations in the past. This is most appropriate in domains which are not well understood, or where any rules that may have been devised have frequent exceptions. CBR thus offers a useful approach to building applications that support decisions based onpast ...
Building a set / reset function with two different coils introduces a new problem: Which one of them has the highest priority? If both conditions for setting and for resetting is true, what will the state of the coil be in the end?
A powerful programming language is one which allows you to get a lot done with few lines of code. While not as robust as languages like C++ or Java, SQL serves a very specific role and does so with incredible efficiency. There are few applications in existence that are as optimized for ...
That’s fine, I’m only interested in getting started (and secretly interested in building my own confidence that I can do this project). I’ve got one of my important items done: display a chessboard. This actually took a bit longer than the code shows, because I also had to figure ...
Let's take a look at a simple system and consider how it might be implemented in relay logic. Suppose that a large laboratory or industrial building is to be equipped with a fire alarm system, activated by any one of several latching switches installed throughout the facility. The system sh...
The next step is to develop the program logic using the programming software provided by the manufacturer. This is the core of what makes a PLC function, defining how it will process input data during operations. Once the logic is complete, the program will need to be compiled so that it ...
