Latest Patents
One of his latest patents is titled "System and method for unsupervised text normalization using distributed representation of words." This invention provides a system and method for the unsupervised normalization of noisy text by utilizing a distributed representation of words. The system receives a word with a non-canonical spelling from a social media forum and determines its context. It identifies the word in a vector space model and selects 'n-best' vector paths based on the context and the non-canonical spelling. Ultimately, it identifies a canonical version of the word based on a similarity cost.
Another significant patent is "Unsupervised topic modeling for short texts." This invention determines topics for short text messages using an unsupervised topic model. A training corpus is created from various short text messages, and a vocabulary of words is identified. Each word is processed to obtain a distributed vector representation. The corpus is modeled as a Gaussian mixture model, where Gaussian components represent different topics. The system can then determine the topic of a sample short text message using this model.
