However, research in WSD for Indonesian is still rare to find. The availability of English-Indonesian parallel corpora and WordNet for both languages can be used as training data for WSD by applying Cross-Lingual WSD method. This training data is used as an input to build a model using supervised machine learning algorithms. Our research also examines the use of Word Embedding features to build the WSD model.",

Word Sense Disambiguation (WSD) is a task to determine the correct sense of an ambiguous word.
The training data was collected from news websites and manually annotated. The words in training data were processed using the morphological analysis to obtain lemma.
The features being used were some words around the target word (including the words before and after the target word), the nearest verb from the
target word, the transitive verb around the target word, and the document context.
