Information Processing Models and Computer Aids for Human Performance. Task 4: Studies of Human Memory and Language Processing
Abstract
The aim of the project was to determine how people store and retrieve factual (non-numerical) information and how they utilize this stored information in comprehending English text. Three of the studies investigated how people retrieve factual information, one evaluated possible strategies for interpreting text, and a final paper summarized conclusions about the requirements for building a computer-based, natural language-processing system. The results indicated that people use both deductive inference and inference by analogy in answering questions. The initial search for relevant facts is apparently a parallel process, while the checking of possible answers is a serial process. Depending on the information turned up by the parallel search and the constraints of syntax and context, people apply a variety of different specific decision rules in order to decide how to answer a question or how to interpret a sentence. Military operations in the future will utilize computer-based, question-answering systems that can store and retrieve factual information and that can interact with users in English. Knowledge gained from these experiments is being used in a computer project aimed toward developing such systems.
