    <Paragraph position="0"> This paper reviews the Basque lexical-sample task organized for Senseval 3. Each participant was provided with a relatively small set of labelled examples (2/3 of 75+15*senses+7*multiwords) and a comparatively large set of unlabelled examples (roughly ten times more when possible) for around 40 words. The larger number of unlabelled data was released with the purpose to enable the exploration of semi-supervised systems.</Paragraph>
    <Paragraph position="1"> The test set comprised 1/3 of the tagged examples.</Paragraph>
    <Paragraph position="2"> The sense inventory was taken from the Basque WordNet, which is linked to WordNet version 1.6 (Fellbaum, 1998). The examples came mainly from newspaper texts, although we also used a balanced in-house corpus and texts from Internet. The words selected for this task were coordinated with other lexical-sample tasks (such as Catalan, English, Italian, Romanian and Spanish) in order to share around 10 of the target words.</Paragraph>
