IG Parser

IG Parser is a tool that parses institutional statements in the IG Script notation, which allows for the machine-accessible parsing of institutional information, and it introduced as part of the IG Book. The specific examples of encoded institutional statements referenced throughout Chapters 7 and 8 in the book can be found under Book Examples.

The current version of IG Parser is available in two versions that both take IG Script as input, but produce different output, selectively focusing on tabular output, as well as a tree output for visual exploration of the parsing outcome based on interactive navigation.

When opening the parser, you will see input fields, the first of which merely takes any original (i.e., unparsed) statement as reference, and a second field that asks for the "Encoded Statement". This field requires IG Script input (Guidance is provided in the corresponding IG Parser help and the links below). In addition, you can parameterize the output to consider relevant features (e.g., IG Extended output -- to take fine-grained nesting into account; Semantic annotations to include IG Logico annotations in the output).

• The tabular version (Google Sheets, CSV output (e.g., for Excel processing)) can be found here:

• The visual version (tree output format) can be found here:

An overview of the IG Script syntax supported by the IG Parser is provided here. The code repository is available on Github.
