Fulfilling of milestones
Before starting the project we wrote down some
milestones and deliverables. We will now show
that almost all milestones have been fulfilled.
- Lexicon work
- Morphological rules for inflection of any word in the lexicon have been
constructed and optimized. We had hoped to be able to use SAOL 12 for this
but Svenska Akademien has still, after a year, not come to a decision
on whether we could be allowed to use it.
- Guessing word tags for unknown words
- The word tag guesser has been improved in several ways and now tags 91 %
of the words correctly, much better than our goal of 85 %.
Our report describing the techniques used for tagging has recently
been published [Carlberger and Kann, 1999].
- Replacement proposals
- Algorithms for generation of replacement proposals have been implemented.
This includes generation of spelling error replacement proposals and
grammar error replacement proposals, but not yet any order of precedence
for the proposals when several proposals are given
for the same spelling or grammar error.
Replacement proposal generation rules have been written for
almost all grammar-checking rules.
- Grammar checking rules construction
- A specification of error types that we want Granska to detect
has been written [Domeij and Knutsson, 1999].
We have compared the list to
similar lists for commercial Swedish grammar checkers
and found that our list covers most errors and contains error types that are
not detected by other grammar checkers, for example
In particular we have studied, implemented and evaluated rules for
two error types: split compounds and incongruence in nominal phrases.
A report will be presented [Domeij, Knutsson, and Öhrman, 1999].
- User interface design and implementation
Connecting the graphical user interface and the grammar error detection module
has been unexpectedly hard, but progress is done.
Design of interface components for POS lexicon editing and replacement
suggestions will not be done in this project.
A text-based interface to Granska has been implemented and connected
to the grammar error detection module. A web interface is under construction,
- Linguistic search and editing
- An empirical study of revision patterns has been performed and a report
has been written [Tyndall, 1999].
- Swedish language rules and help system
- A draft of the new version of Svenska skrivregler has been completed.
The design of the help system in HTML has been specified.
