While automatic text summarization is an area that has received a great deal of attention in recent research, the problem of efficiency in this task has not been frequently addressed. When the size and quantity of documents available on the Internet and from other sources are considered, the need for a highly efficient tool that produces usable summaries is(More)
Tills paper describes a computational method for correcting users' miseonceptioas concerning the objects modelled by a compute," s.ystem. The method involves classifying object-related misc,mce|,tions according to the knowledge-base feature involved in the incorrect information. For each resulting class sub-types are identified, :.:cording to the structure(More)
Responses to misconceptions given by human conversational partners very often contain information refuting possible reasoning which may have led to the misconceptions. Surprisingly there is a great deal of regularity in these responses across different domains of discourse. For instance, one reason a user might have given an object a property it does not(More)
omputers and computer-based technology have become an integral part of the lives of many individuals with physical disabilities. One of the most common activities that can be computer-assisted is the generation of text. People who cannot accurately control their extremities (due to disabilities such as cerebral palsy and spinal cord injury) use computers as(More)
Word prediction systems can reduce the number of keystrokes required to form a message in a letter-based AAC system. It has been questioned, however, whether such savings translate into an enhanced communication rate due to the additional overhead (e.g., shifting of focus and repeated scanning of a prediction list) required in using such a system. Our(More)
In order to produce coherent text. natural language generation systems must have the ability to generate pronouns in the appropriate places. In the past, pronoun usage was primarily investigated with respect to the accessibility of ref-erents. We.argue that generating appropriate referring expressions requires looking at factors beyond accessibility. Also(More)
This paper describes the design, implementation, and impact evaluation of a summer program designed to attract high school girls to entering an information technology field for their college major. Our main contributions include an analysis of immediate and longer term surveys from both the student participants and the female teaching assistants, curriculum(More)
The ICICLE project is a Computer-Assisted Language Learning (CALL) environment geared toward teaching English as a second language. This paper reports on an initial prototype application of the system for deaf learners of written English. A primary focus of the ICICLE effort has been devoted to enabling the system to adapt to a learning user over the(More)
