PyLFG Help

PyLFG is a web-based tool for teaching, learning, and researching Lexical Functional Grammar (LFG). This tool allows users to enter sentences, grammars, and lexicons in the LFG formalism, and see the resulting c-structure and f-structure parse trees.

Input View

The Input View is the main page of the PyLFG tool. Here, users can enter a sentence to be parsed, select a grammar to use for parsing, and choose which parse tree(s) they would like to see (c-structure, f-structure, or both). The input view also has a link to the Help View for more information.

Results View

The Results View displays the c-structure and/or f-structure parse tree(s) for the sentence and grammar selected in the Input View. This view also includes a link to the Input View for parsing another sentence.

Help View

The Help View provides information on how to use the PyLFG tool and what the different views and features are.
