Given the annotated corpus D , we use a word w i or a mention sense s * j to predict the context words by maximizing the following objective function: where s * j = g(< m l , e j >) is obtained from anchors in Wikipedia articles.
words and mention senses will share the same vector space, where similar words and mention senses are close to each other, such as celebrations and Independence Day (US) because they frequently occur in the same contexts.
