Four papers are included in Part One of the eighteenth report on Salton's Magical Automatic Retriever of Texts (SMART) project. The first paper: "Content Analysis in Information Retrieval" by S. F. Weiss presents the results of experiments aimed at determining the conditions under which content analysis improves retrieval results as well as the degree of improvement obtained. The second paper: "The 'Generality' Effect and the Retrieval Evaluation for Larger Collections" by G. Salton assesses the role of the generality effect in retrieval system evaluation and gives evaluation results for the comparisons of several document collections of distinct size and generality in the areas of documentation and aerodynamics. In the third paper: "Automatic Indexing Using Bibliographic Citations" by G. Salton citations are used directly to identify document content and an attempt is made to evaluate their effectiveness in a retrieval environment. The final paper: "Automatic Resolution of Ambiguities from Natural Language Text" by S. F. Weiss discusses the evolutionary process by which ambiguities are created and classifies ambiguities into three classes: true, contextual and syntactic.
