We are pleased to announce the release of UBY 1.0 - a large-scale 
lexical-semantic resource for natural language processing (NLP) based 
on the ISO standard Lexical Markup Framework (LMF):

http://www.ukp.tu-darmstadt.de/data/uby/

UBY combines a wide range of information from expert-constructed 
and collaboratively constructed resources for English and German.
Currently, UBY holds structurally and semantically interoperable 
versions of nine resources in two languages:

* English WordNet, Wiktionary, Wikipedia, FrameNet and VerbNet,
* German Wikipedia, Wiktionary and GermaNet, and multilingual 
OmegaWiki.

A subset of these resources is linked at the word sense level. There 
are monolingual sense alignments between VerbNet-FrameNet and 
VerbNet-WordNet as well as between WordNet-Wikipedia and 
WordNet-Wiktionary.

In addition, UBY provides cross-lingual sense alignments between 
WordNet and German OmegaWiki, also including the inter-language 
links given in Wikipedia and OmegaWiki.

All resources in UBY are represented according to our LMF lexicon 
model, UBY-LMF.

UBY-LMF captures lexical information at a ﬁne-grained level by 
employing a large number of Data Categories from  ISOCat.

Highlights of UBY:

* The union of a wide range of heterogeneous resources in a single, 
standardized resource.
* The linking at the word sense level between a subset of the 
resources.

UBY is complemented by a Java API, the UBY-API, and conversion 
tools (e.g., for converting the resources to UBY-LMF).

The UBY API and conversion tools are available at Google Code:

http://code.google.com/p/uby/

Highlights of the UBY-API:

* Unified access to the various information types in the nine resources.
* Easy cross-resource access to the various information types in the 
resources.

A tutorial showing the use of the UBY-API can be found at

http://code.google.com/p/uby/wiki/ApiTutorial

A Web Interface for exploring and visualizing UBY is currently being 
developed and will soon be available at http://www.ukp.tu-
darmstadt.de/data/uby/.

This project was initiated under the auspices of Prof. Dr. Iryna 
Gurevych, Ubiquitous Knowledge Processing Lab (UKP), Technische 
Universität Darmstadt.

We are grateful for the generous financial support from the 
Volkswagen Foundation and the German Research Foundation.

This Year the LINGUIST List hopes to raise $67,000. This money will go to help 
keep the List running by supporting all of our Student Editors for the coming
year.

Drive 2012 site!

Alternatively you can also pledge right now and pay later. To do so, go to: 
https://linguistlist.org/donation/pledge/pledge1.cfm

For all information on donating and pledging, including information on how to

The LINGUIST List is under the umbrella of Eastern Michigan University and as 
such can receive donations through the EMU Foundation, which is a registered 
501(c) Non Profit organization. Our Federal Tax number is 38-6005986. These 
donations can be offset against your federal and sometimes your state tax
return (U.S. tax payers only). For more information visit the IRS Web-Site,
or contact your financial advisor.

Many companies also offer a gift matching program, such that they will match 
any gift you make to a non-profit organization. Normally this entails your 
contacting your human resources department and sending us a form that the 
EMU Foundation fills in and returns to your employer. This is generally a
simple administrative procedure that doubles the value of your gift to
LINGUIST, without costing you an extra penny. Please take a moment to check if
your company operates such a program.

Thank you very much for your support of LINGUIST!
