Experimentation and analysis dominate the activities with the Intrex information storage and retrieval system. Detailed analysis of the retrieval effectiveness of the Intrex-System configuration have been made in an effort to establish, quantitatively, the value of free-vocabulary and deep subject indexing; the usefulness of various fields of information such as title, abstract, subject-index phrases and so forth as indicators of desired information; and kinds of retrieval strategies that yield most complete and satisfying results. An experiment with the Massachusetts Institute of Technology (M.I.T.) compatible time-sharing computer in which a cluster of users simultaneously engaged the machine for information-retrieval purposes yielded valuable information for future designers of time-sharing systems dedicated exclusively to information retrieval. Details of this experiment are presented in Section B of this report. A thesis on Digital Communication Networks for Information Storage and Retrieval Systems has been presented by Mr. H. V. Jesse in satisfaction of requirements for his Electrical Engineer degree. His results are summarized in Section F. A detailed analysis of the performance reliability of the Intrex full-text storage and retrieval system has been made. The salient points of the study are discussed in Section G. (Author/NH)
