Multilingual Word Sense Disambiguation SemEval 2013 - Task #12

http://www.cs.york.ac.uk/semeval-2013/task12/

The aim of this task is to evaluate Word Sense Disambiguation
systems in an all-words multilingual setting.

INTRODUCTION

Task 12 provides a traditional setup for evaluating Word Sense
Disambiguation (WSD) systems in an all-words, multilingual
setting by marking occurrences of potentially polysemous words in
five different languages (English, French, German, Italian,
Spanish) with sense labels provided by a multilingual sense
inventory. To enable multilinguality we make use of the BabelNet
sense inventory [1], a wide-coverage semantic network built by
merging WordNet with Wikipedia to provide an "encyclopedic
dictionary." BabelNet concepts are lexicalized in many languages
using Wikipedia's inter-language links and the output of a
state-of-the-art machine translation system. Task 12 will use a
validated version of BabelNet 1.1 (http://babelnet.org) in which
the Wikipedia-WordNet mappings of all senses of lemmas in the
test data have been manually verified.

PARTICIPANT SENSE INVENTORY

Participants are free to work on the full BabelNet sense
inventory or to work on either of its inventory subsets, i.e.
WordNet 3.0 or Wikipedia page titles. They are also free to
participate using a single language of their choice or all five
languages.

TASK DETAILS:

Following the traditional WSD "all-words" experimental setting
[2], systems will be expected to link all occurrences of noun
phrases within arbitrary texts in different languages to the most
suitable senses in the sense inventory of their choice. For
instance, given the sentence:

    The dramatic force of Miller's play derives in part from
    expressionistic techniques he used to portray Loman's
    psychological anguish and guilt-ridden fantasy life.

a disambiguation system should link "Miller" to any of (1) the
BabelNet synset for Arthur Miller, (2) the Wikipedia sense
corresponding to the page
http://en.wikipedia.org/wiki/Arthur_Miller, or (3) Miller#n#3
(i.e. the third WordNet sense for Miller), depending on the
participant's choice of sense inventory. Note that the BabelNet
synset will contain where applicable both the Wikipedia page and
the WordNet synset in its representation.

Participants will be evaluated in groups based on their choice of
sense inventory and target language. All the information about
the submitted systems (such as training data, resources, etc.
used by the system) will be reported in the task paper.

DATASETS:

No training data will be provided as a part of this task;
however, participants are allowed to use any freely available
training data for building their system.

For annotating the test set, by mid-February we will provide a
gold standard version of BabelNet 1.1 where all synsets used in
the test data have been manually verified for correctness.
