Subject: Machine Translation of Prepositional Phrases
A while back, I posted a message requesting pointers to
1. articles directly addressing the problem of _Machine Translation_
of prepositional phrases - in particular, previous proposed solutions
and/or implementations/evaluations of those solutions.
and
2. articles relating to evaluation of the current state of the art in
PP translation. Both a) pointers to articles and b) suggestions for
handling the fact that there may not be numeric (hard, factual)
metrics that demonstrate that PP translation is an area in MT that
needs improvement would be appreciated.
I would like to thank all who responded:

Their responses are incorporated into the summary below.
I. Articles addressing the Machine Translation of Prepositional
Phrases
With respect to the first request above, as John Hutchins notes "there
are few treatments specifically devoted to prepositional phrases in
MT. However, this problem area will have been treated in the context
of valency, case grammar, and general syntactic and semantic analysis
-- particularly for languages such as Japanese, German and Russian."
I have certainly found this to be the case. Nonetheless, he and
several others did uncover several references pertaining specifically
to the MT of PPs. These are listed below. In particular, two
Ph.D. theses have recently been completed that deal with prepositions
in machine translation: Reyero-Sans (1998) and Trujillo (1995).
In addition to specific articles, I received a couple of pointers to
projects/departments:
There is work at the University of Helsinki on the translation from
Finnish case endings to English prepositions.
I was referred to the "Catalyst Project" at CMU, where there was
detailed empirical work done on the semantic categorization of English
PPs, starting from the discussion of PP usage in Quirk et al., and the
subsequent arrangement of the resultant categories into a hierarchy.
Similar analyses were done for the target languages.
II. Evaluation of the current state of the are in PP translation
Unfortunately, with respect to the second request, the jury seems
still to be out. This is not surprising, given the lack of agreement
surrounding MT evaluation methodologies. Several people did cite
internal evaluations of systems, often stating that performance on PPs
was not broken out specifically. One respondent gave a personal
impression that the system correctly translates 75-80% of PPs, based
on human inspection of the output.
As a way of handling the fact that there are no 'benchmark' numbers in
the literature for the translation of PPs, it was suggested that
Systran be used as the gold standard - comparing the rate of correct
translations of PPs by Systran to that of whatever approach(es) I
suggest in my work, in order to determine an upper bound on the
improvement expected based on my methods. It was further suggested
that I could perform a direct comparison of my methods to available MT
systems, using a human translation as the standard. I am interested to
hear any reactions (positive or negative) to this methodology.
Thanks again to all who responded.

Below is a compilation of the references sent by people responding to
my initial query. Some I was previously aware of; many I was not. For
completeness, I have attempted to include all references and pointers
to information that were provided to me. The (somewhat rough)
classification of references is mine, and is used in an attempt to
give some structure to the list. It is based on information from the
person providing the reference, a quick glance at the material, or in
some cases, simply from the title of the reference itself.
