SWI-Prolog is neither a commercial Prolog system nor a purely academic enterprise, but increasingly a community project. The core system has been shaped to its current form while being used as a tool for building research prototypes, primarily for knowledge-intensive and interactive systems. The SWI Prolog Language Server is designed to enable embedding SWI Prolog into just about any programming language (Python, Go, C#, etc) in a straightforward way. It is designed for scenarios that need to use SWI Prolog as a local implementation detail of another language. Think of it as running SWI Prolog 'like a library'. SWI-Prolog is a fast and powerful ISO/Edinburgh-style Prolog compiler with a rich set of built-in predicates. It offers a fast, robust and small environment which enables substantial applications to be developed with it.

Searching Internet for research papers - tips
- Add
pdfas a keyword as it dramatically improves finding the paper if it is indexed by the search engine and avialble as a PDF. - Some times the paper is not indexed by a search engine because the paper is stored on the public site of a professor but robots.txt excludes indexing personal pages. So if you know the author(s), go to their school site, search for the author, find their personal pages and manually search them. This has a low probably of working, but does sometimes work when Google or such fails.
