In formal language theory, deterministic context-free languages (DCFL) are a proper subset of context-free languages. They are the context-free languages that can be accepted by a deterministic pushdown automaton. DCFLs are always unambiguous, meaning that they admit an unambiguous grammar. There are non-deterministic unambiguous CFLs, so DCFLs form a proper subset of unambiguous CFLs. DCFLs are of great practical interest, as they can be parsed in linear time, and various restricted forms of DCFGs admit simple practical parsers. They are thus widely used throughout computer science. (Wikipedia).

7.1: Intro to Session 7: Context-Free Grammar - Programming with Text
This video introduces Session 7: Context-Free Grammar from the ITP course "Programming from A to Z". A Context-Free Grammar is a set of recursive "replacement" rules to generate text. In this session, I discuss two JavaScript libraries: Tracery and RiTa.js for working with context-free gr

Semistructured data is an umbrella term encompassing data models which are not logically organized in tables (i.e., the relational data model) but rather in hierarchical structures using markers such as tags to separate semantic elements and data fields in a ‘self-describing’ way. In this
