Understanding Malformed Text with Word Embeddings

In recent years word embeddings have become increasingly popular, constituting a building block for many practical applications across NLP, ML, Search and related disciplines. The power of word embeddings stems from the fact that they allow us to represent words as vectors of real numbers of arbitrary dimensionality in such a way, that a distance in the vector space can be interpreted as a measure of semantic similarity between the words. One of the limitations of many existing techniques, however, is their inability to represent malformed words. In this talk, we will discuss the challenges state of the art word embedding methodologies face when applied to real-world, human-generated text. We will explore strategies of alleviating some of these problems and discuss how we can leverage word embeddings to work well on misspelled texts.
