-======================
-The FraCaS GF Treebank
-======================
-
-:Authors: Peter Ljunglöf, Magdalena Siverbo

-1. Introduction
-===============
-
-This is the FraCaS Treebank, developed and maintained by
-the Centre for Language Technolgy at University of Gothenburg:
-
- http://www.clt.gu.se/
-
-The treebank is part of the CLT Toolkit, a set of state-of-the-art
-open source Language Technology tools and accompanying linguistic
-resources. The different parts of the toolkit, including the
-FraCaS Treebank, can be downloaded from:
-
- http://www.clt.gu.se/clt-toolkit
-
-The treebank is built upon the FraCaS textual inference problem set,
-which was built in the mid 1990’s by the FraCaS project, a large
-collaboration aimed at developing resources and theories for
-computational semantics. This test set was later modified and
-converted to XML by Bill MacCartney:
-
- http://www-nlp.stanford.edu/~wcmac/downloads/fracas.xml
-
-It is this modified version that has been used in this treebank.
-The corpus consists of 346 problems each containing one or more
-statements and one yes/no-question (except for four problems, where
-there is no question). The total number of sentences in the corpus is
-1220, but since some of them are repeated in several problems, there
-are in total 874 unique sentences.
-
-2. Description
-==============
-
-The treebank is created in Grammatical Framework (GF), using its
-multilingual Resource Grammar as backend grammar. Currently the
-treebank is bilingual, with an English and a Swedish lexicon.
-
-More information about GF, including installation instructions,
-can be found at:
-
- http://www.grammaticalframework.org/
-
-The treebank is also distributed in XML and Prolog formats,
-for people that have no interest in learning GF. Note however
-that the syntactical constructions come from the GF resource grammar.
-
-3. Download and installation
-============================
-
-The full distribution can be downloaded from
-`<dist/FraCaSBank-0.2.zip>`_.
-
-The Prolog and XML treebanks are already generated, so to use these
-you don't need anything else. But if you want to work with the GF
-source files, you need a GF installation including the Resource Grammar.
