Hi everyone,
A new release of the Attempto Parsing Engine (APE) is available for download (version 6.5-091130):
http://attempto.ifi.uzh.ch/site/downloads/
Though we have many ideas and also requests to extend Attempto Controlled English, this release
serves mainly to consolidate the current status and contains no new language features.
The Attempto Parsing Engine (APE) was tested extensively which revealed a few bugs that we
subsequently fixed:
* Adjectives used with the construct "as ... as" were sometimes represented incorrectly.
* Rare forms of combining relative clauses and anaphoric references did not work.
* Scopes were represented incorrectly in some rare cases.
* For some questions, parsing failed but succeeded if a full stop instead of a question mark was
used.
* In some rare cases, parsing succeeded for irreflexive pronouns where reflexive pronouns should
have been used.
* In some cases, proper names with relative clauses did not work properly with anaphoric
references.
* There were several small bugs in the resolution of anaphoric references.
* Unknown words were not reported if the first sentence succeeded.
Also we cleaned up the code of APE and improved its internal documentation.
APE's paraphraser was slightly amended:
* It now correctly chooses "a" or "an".
* If the paraphraser cannot generate a paraphrase - for instance for distributed plurals, some
questions, some cases of sentence subordination - it generates the ACE comment "# ..."
instead.
APE's TPTP output:
* The TPTP output was improved.
* Several bugs were fixed.
In brief, APE is now in a very stable state.
