Hi everybody,
I have been working on the idea for creating an interface for tagged
corpora since the past few days. I have finished the coding challenge, have
gone through the documentation pdf and wikis and am currently working on
designing the interface. I am posting the mockups for the interface so
that I can get your opinion and improve on them.
There are currently three major interfaces:
a) Manual disambiguator
b) .prob evaluator
c) .tsx file editor
I have put up all the mockups together at http://imgur.com/a/4uk4q#r5Ur8jT and
have also put links in separate sections.
*a) Manual disambiguator*
Mockup: http://i.imgur.com/r5Ur8jT.png
Functions:
- Jump to next ambiguous lexical unit or adjacent lexical-unit using the
keyboard or mouse.
- A quick-view bound to a key, to hide the tags and show the raw text
- If the .tsx file is provided, information like the coarse tags,
forbid, enforce rules applicable can also be displayed.
- Show statistics of disambiguation
- Compile and apply constraint grammar rules to the buffer
- List the applied constraint grammar rules
- Train and test the tagger (a prompt will ask the part of the corpus to
be used as testing data).
- Train the tagger and export the .prob file
- Save progress ( this will save the corpus and also create a project
description file which will keep track of the morphological analyser, .tsx
files used, so that it is easier to resume tagging)
- The interface will be keyboard centric, though it will be equally
functional with a mouse.
- Default keymaps will be provided and the bindings can be changed to
suit the user
For example
[P] - <previous-ambiguous>
[N] - <next-ambiguous>
[F] - <forward-word>
[B] - <back-word>
[1], [2],[3],[4] for choosing the correct lexical form.
*Evaluating the tagger*
Functions
- The trained tagger can be evaluated immediately by having an option of
setting aside x% of the corpus as testing data.
- Else, it can be evaluated using the .prob evaluator using an unrelated
corpus.
*Loading the corpus*
The available options are:
1.
Load a raw-text file, morphological analyser and .tsx file (optional)
2.
Continue on an existing project
3.
Pull a wiki-dump and use it as the corpus [

*b) .prob evaluator*
Mockup: http://i.imgur.com/fIo6rV9.png
Functions
- Input the .prob file , the manually disambiguated corpus along with
morphologically analysed corpus or the morphological analyser for the
language.
- Evaluate the .prob file and display statistics about tagger accuracy
- Generate a log file, which will basically be the diff between the
provided tagged corpus and the corpus disambiguated by the tagger, making
it easier to frame new sentences to add to the corpus, so as to give more
context to the tagger
*c) .tsx file editor*
Mockup:
TSX Viewer

Templates
http://i.imgur.com/hFGIQHR.png
Functions:
-
Add new tags
- categories
- multi-categories
- forbid
- enforce
- prefer
- Templates for adding new tags
- Change the order of the tags (as more specific categories must be
defined before more general ones) within the same parent tag. The nodes in
the xml viewer can also be made draggable within the same parent node to
make it easier to change the order
- Search within tags for faster navigation.
- Validate the tagger definition
- Editor features like syntax highlighting , auto-indentation and tag
completion for manual editing in the Node Contents textview for complex
in-place editing.
Looking forward to hear from you. :)
