This technical report describes a study designed to construct and validate a set of sentence materials necessary to the pursuance of a long-term research project on information analysis and integration in semantically-rich, naturalistic domains. This study complements the ones described in a previous report. The necessity for materials construction arises from the capricious character of natural materials within the primary semantic domain of this project, namely, the stock market. We were able to select and modify from natural materials a large pool of 242 sentences pertinent to the market behavior of stock issued by typical American companies. We determined that relatively naive subjects could reliably categorize these sentences as being pertinent to one of six categories of information, General Factors, Capitalization, Growth, Sales, Earnings and Dividends, and that these sentences could be reliably rates as to their prognostic information regarding market behavior of the company. On the basis of rating and categorization study, three sets of sentences were generated. Set I consisted of 120 sentences, 20 falling within each category of information and representing a uniform distribution of ratings over a 5-point scale. Set II contains 3 nonambiguous sentences that are generally lower in category agreement to the sentences in Set I. Set III consists of eleven sentences with ambiguous category ratings. Several applications are described, using the scaled sentences in text generation and accounting for the uncertainty in the sentences in concept learning studies. Author
