Poster by Sumedh Masulkar. Guided by Prof. Amitabh Mukherjee. INTRODUCTION. Word Sense Induction is the method to deduce automatically the senses or uses of a given word with multiple meanings (known as target word) directly from a text without relying on any external resources such as dictionaries or sense-tagged data. It is also known as unsupervised Word Sense Disambiguation, since Word Sense Induction(WSI) methods automatically disambiguates the ambiguous occurrences of a given word.
