IGT Editor

Editor for IGT instances and corpora (WPF)

There are two executables related to IGT editing, the converter (igt-convert) and the editor (igt-edit). Both require a version of Windows compatible with .NET 4.5 (that is, Vista or later, Windows XP is not supported). Windows 8 and later include the required version. For Windows 7 and Vista you may need to install .NET 4.5.1 from:

igt-convert (igt-convert.exe)

This console mode program batch-converts an entire directory of igt-text (e.g. ODIN) files into the XAML format used by the editor. This conversion only needs to be done once; the editor reads and writes the XAML IGT format.

The conversion includes a few pre-configured conversion operations:

• A single TextTier is created to preserve the original source text.
• Tiers are grouped according to tier type, such that one TierGroupTier is created for each distinct type. Source lines tagged with multiple tier types are repeated (copied) and placed into each indicated group.

ODIN test and train data from the aggregation project has been pre- converted and can be found in the odin-xaml directory.

XAML-IGT format

The following is a sample of the XAML-igt format which the igt-edit program reads and writes. This example shows the results of the built-in conversion operations mentioned above.

The 'xmlns' (namespace) directive on the root element of the document is required in every XAML-igt file as shown.

Support for the XAML-IGT format is provided by the igt-xaml.dll class library.

igt-convert usage

igt-convert.exe [input-dir] [output-dir]

Converts each ODIN text format IGT file (.txt) in the input directory to a XAML IGT file (.xml) in the output directory. Existing files with a conflicting name in the output directory are overwritten.

ODIN text files are UTF-8 files containing zero or more IGT instances which adhere to the (e.g.) following format. Instances must be separated by a blank line. Line feed format can be either Unix or DOS/Windows.

doc_id=807 2764 2766 L G T language: spanish (spa) + english (eng) line=2764 tag=L: (77a) *Juan está eat-iendo line=2765 tag=G: Juan be/1Ss eat-DUR line=2766 tag=T: `Juan is eating.'

The output file format is a XAML serialization of the object graph for the in-memory object model of the WPF IGT editor.

igt-edit (igt-edit.exe)

The editor is a graphical application which allows free-form, random access editing of multiple IGT corpora, each containing multiple IGT instances.

The editor reads and writes XAML-igt files. This hierarchical XML file format is human readable and can be edited by hand or with scripts, although care must be taken to adhere to maintain readability of the object graph.

Sources

github source repository for igt-edit and igt-convert:

https://github.com/glenn-slayden/igt-editor/

The editor is a .NET/WPF (Windows Presentation Foundation) graphical application which requires Windows and .NET 4.5.1

Although the converter is a console application, it also cannot be built under Mono since it depends on the WPF objects used by the editor app.
