Trnka, Keith, McCaw, John, Yarrington, Debra, McCoy, Kathleen F. and Pennington, Christopher (2008): User Interaction with Word Prediction: The Effects of Prediction Quality. In ACM Transactions on Accessible Computing, 1 (3) p. 17

“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 hypothesis is that word prediction has high potential for enhancing AAC communication rate, but the amount is dependent in a complex way on the accuracy of the predictions. Due to significant user interface variations in AAC systems and the potential bias of prior word prediction experience on existing devices, this hypothesis is difficult to verify. We present a study of two different word prediction methods compared against letter-by-letter entry at simulated AAC communication rates. We find that word prediction systems can in fact speed communication rate (an advanced system gave a 58.6% improvement), and that a more accurate word prediction system can raise the communication rate higher than is explained by the additional accuracy of the system alone due to better utilization (93.6% utilization for advanced versus 78.2% for basic).”

Trnka, Keith and McCoy, Kathleen F. (2007): Corpus studies in word prediction. In: Ninth Annual ACM Conference on Assistive Technologies 2007. pp. 195-202. Available online

“Word prediction can be used to enhance the communication rate of people with disabilities who use Augmentative and Alternative Communication (AAC) devices. We use statistical methods in a word prediction system, which are trained on a corpus, and then measure the efficacy of the resulting system by calculating the theoretical keystroke savings on some held out data. Ideally training and testing should be done on a large corpus of AAC text covering a variety of topics, but no such corpus exists. We discuss training and testing on a wide variety of corpora meant to approximate text from AAC users. We show that training on a combination of in-domain data with out-of-domain data is often more beneficial than either data set alone and that advanced language modeling such as topic modeling is portable even when applied to very different text.”

“The rapid growth of the Internet has resulted in enormous amounts of information that has become more difficult to access efficiently. Internet users require tools to help manage this vast quantity of information. The primary goal of this research is to create an efficient and effective tool that is able to summarize large documents quickly. This research presents a linear time algorithm for calculating lexical chains which is a method of capturing the "aboutness" of a document. This method is compared to previous, less efficient methods of lexical chain extraction. We also provide alternative methods for extracting and scoring lexical chains. We show that our method provides similar results to previous research, but is substantially more efficient. This efficiency is necessary in Internet search applications where many large documents may need to be summarized at once, and where the response time to the end user is extremely important.”

Michaud, Lisa N., McCoy, Kathleen F. and Pennington, Christopher A. (2000): An Intelligent Tutoring System for Deaf Learners of Written English. In: Fourth Annual ACM Conference on Assistive Technologies 2000. pp. 92-100. Available online

“This paper describes progress toward a prototype implementation of a tool which aims to improve literacy in deaf high school and college students who are native (or near native) signers of American Sign Language (ASL). We envision a system that will take a piece of text written by a deaf student, analyze that text for grammatical errors, and engage that student in a tutorial dialogue, enabling the student to generate appropriate corrections to the text. A strong focus of this work is to develop a system which adapts this process to the knowledge level and learning strengths of the user and which has the flexibility to engage in multi-modal, multi-lingual tutorial instruction utilizing both English and the native language of the user.”

McCoy, Kathleen F., Demasco, Patrick, Pennington, Christopher A. and Badman, Arlene Luberoff (1997): Some Interface Issues in Developing Intelligent Communications Aids for People with Disabilities. In: Moore, Johanna D., Edmonds, Ernest and Puerta, Angel R. (eds.) International Conference on Intelligent User Interfaces 1997 January 6-9, 1997, Orlando, Florida, USA. pp. 163-170. Available online

“Augmentative and Alternative Communication (AAC) is the field of study concerned with providing devices and techniques to augment the communicative ability of a person whose disability makes it difficult to speak in an understandable fashion. For several years, we have been applying natural language processing techniques to the field of AAC in order to develop intelligent communication aids that attempt to provide linguistically "correct" output while speeding communication rate. In this paper we describe some of the interface issues that must be considered when developing such a device. We focus on a project aimed at a group of users who have cognitive impairments that affect their linguistic ability. A prototype system is under development which will hopefully not only prove to be an effective communication aid, but may provide some language intervention benefits for this population.”

McCoy, Kathleen F., Demasco, Patrick W., Jones, Mark A., Pennington, Christopher A., Vanderheyden, Peter B. and Zickus, Wendy M. (1994): A Communication Tool for People with Disabilities: Lexical Semantics for Filling in the Pieces. In: First Annual ACM Conference on Assistive Technologies 1994. pp. 107-114.

“The goal of this project is to provide a communication tool for people with severe speech and motor impairments (SSMI). The tool will facilitate the formation of syntactically correct sentences in the fewest number of keystrokes. Consider the situation where an individual is using a word-based augmentative communication system -- each word is (basically) one keystroke and morphological endings etc. require additional keystrokes. Our prototype system is intended to reduce the burden of the user by allowing him/her to select only the uninflected content words of the desired sentence. The system is responsible for adding proper function words (e.g., articles, prepositions) and necessary morphological endings. In order to accomplish this task, the system attempts to generate a semantic representation of an utterance under circumstances where syntactic (parse tree) information is not available because the input to the system is a compressed telegraphic message rather than a standard English sentence. The representation is used by the system to generate a full English sentence from the compressed input. The focus of the paper is on the knowledge and processing necessary to produce a semantic representation under these telegraphic constraints.”

McCoy, Kathleen F. (1983): Correcting Misconceptions: What to Say when the User is Mistaken. In: Smith, Raoul N., Pew, Richard W. and Janda, Ann (eds.) Proceedings of the ACM CHI 83 Human Factors in Computing Systems Conferenc December 12-15, 1983, Boston, Massachusetts, United States. pp. 197-201.

“Because people's knowledge is often partial and/or faulty, it is inevitable that misconceptions will be revealed in the course of a conversation. If recognized, the other person may say something to correct the misconception, and the conversation continues. Just as this is the case when people interact with each other, so must it be when users interact with a computer system. For example, in interacting with an expert system, a user may reveal misconceptions about objects modelled by the system. By failing to correct such misconceptions, the system may not only confirm the original misconception, but may cause the user to develop further misconceptions. It must therefore be up to the system to recognize and respond to misconceptions in an effective way. In this paper the space of possible object misconceptions is characterized according to the kind of incorrect information involved. It has been found that this characterization is often useful in determining how the user arrived at the misconception, and therefore the kind of information to include in the response. Using such a characterization, a system will be able to effectively correct object misconceptions in a domain independent way. Factors which affect the amount of information included in a correction (such as discourse and situational context) are also examined.”
