The information revolution has produced huge quantities of knowledge in natural human language. Every day, more information sources move to the cloud, leading to large scale knowledge collections and tremendous potential for natural language learning. Recent focus on statistical methods has produced numerous high quality tools for processing language, including knowledge extraction, information organization and automated language translation. With more data and better statistical methods, the state of the art advances. However, the confluence of so much diverse data poses significant challenges to common statistical methods, which are often ill suited for large scale learning on diverse genres, topic domains and language dialects.
This talk will present techniques aimed at processing large and diverse natural language collections. I will present Confidence Weighted Learning, a streaming machine learning algorithm designed for the types of data distributions common in language tasks. I will show how Confidence Weighted Learning addresses domain change, in which we seek to apply a statistical system to diverse topic domains. These methods improve learning in natural language processing tasks and can be applied to confront the challenges associated with learning in diverse language settings.
