This page contains links to various scripts, libraries, and packages that people have written to make it easier to work with various DELPH-IN systems and grammar. If you have a tool that you regularly use with the DELPH-IN systems and think might be worth sharing, list it here.

• LKB Linguistic Knowledge Builder

  Grammar development environment, including support for parsing, generation, visualization, and debugging.

• LKB-FOS (John Carroll)

  Fully open-source LKB

• ACE (Woodley Packard)

  ACE (the Answer Constraint Engine) is a processor for DELPH-IN grammars, supporting both parsing and generation.

• PET Platform for Experimentation with efficient HPSG processing Techniques

  An efficient parser for DELPH-IN grammars.

• Agree (Glenn Slayden)

  A a system for processing DELPH-IN style TDL grammars within the .NET and Mono managed runtime environments.

• Converter (Angelina Ivanova)

  Converts ERG derivation tree to bilexical syntactic dependencies, and ERG EDS to bilexical semantic dependencies.

• DelphinTools

  Tools for automatically efficiently running LOGON to create appropriate MRSs: source language, transfer, target language, variational.

• Egad (Michael Goodman)

  Error mining and grammar analysis through generation results (unmaintained, but may still work).

• gDelta (NedLetcher)

  Tool for comparing parser output from two different states of a grammar.

• Grammar Spring Cleaning (Antske Fokkens)

  Tool that removes components of the grammar that are currently not used.

• Linguistic Type Database

  A web interface for grammars made with the LKB that allows easy access to inline documentation and minimal corpus search.

• SHORT-CLIMB (AntskeFokkens)

  Tool that allows you to define modifications to grammar and generates a modified version of the grammar based on the changes (and allows you to convert back)

• Typediff (Ned Letcher)

  A web app for exploring DELPH-IN grammar types used in the processing of input.

• Vista extraction (JoaoSilva)

  Tool for extracting vistas from the files exported by the grammar. Vistas are grammatical representations that collect only a part of the linguistic information encoded in the fully-fledged HPSG grammatical representation.

• DELPH-IN VIZ (NedLetcher)

  Nice interface for online access to the grammar Demo.

• ReppTop

  A Regular Expression Pre-Processor, a finite-state device used to prepare textual input for 'deep' parsing (using DELPH-IN grammars)

• PyDelphin (Michael Goodman)

  Python libraries (and some scripts) for working with DELPH-IN data.

• PyPES (RichardBergmair)

  Python library for scoping, first-order rewriting, and logical inference.

• Ruby delphin gem (Bill McNeill)

  A Ruby package for working with DELPH-IN data and tools.

• Grammar Matrix (Emily Bender and many others)

  Grammar customization system, creates grammars to spec. (https://github.com/delph-in/matrix) and see also MatrixGettingStarted

• AGGREGATION (Emily Bender and many others)

  System for creating grammar specifications based on IGT corpora. (https://git.ling.washington.edu/agg/aggregation)

• http://github.com/delph-in/homebrew-delphin

  Homebrew package repository (tap) of DELPH-IN tools, including ACE and PyDelphin.

• https://github.com/LR-POR/delphin-docker

  This is a docker installation of LOGON, ACE, and its dependents. It has some improvements over the initial LkbMacintosh.

• Heart of Gold: XML-based middleware for the integration of deep and shallow NLP components
