ABSTRACT

There are a multitude of reasons why people may be unable to communicate effectively through verbal speech, including disorders like ALS, MS, Cerebral Palsy and Autism. Some people use augmentative and alternative communication (AAC), which is simply any mode of communication besides verbal speech, including gestures, writing, facial expressions, pointing to pictures and so on. In recent decades, the field of AAC has been flooded by electronic devices which generate speech for these people based on combinations of pictures, symbols and/or words that are stored on the device. Unfortunately, these devices do present problems; notably, the communication rate with a device is reduced to a fraction of the communication rate of normal speakers. The average user of a device is only able to communicate 10 words per minute, compared to the 130-200 words per minute of an average speaker [ref]. This stark contrast can leave users frustrated, reducing the utility of such devices. The aim of this research is to develop a novel algorithm that would increase the communication rate for users of AAC devices.

Project: Named-Entity Recognition
Duration: Summer 2013 – Spring 2014
Funding: Bucknell University Program for Undergraduate Research

ABSTRACT

Liz is working on a system that can annotate all of the named entities within a text. There are good systems that can identify named entities, however, identifying the type of named entity is a more challenging problem. Many successful systems use simple database lookup techniques and identify entities from a master gazetteer. We are working on a system that can distinguish among different types of named entities without a gazetteer. Our initial efforts will focus on distinguishing entities between location, organization, or person. We plan to start by developing a large set of regular expressions that can be used to classify the different types of entities.
