Automatic information organization and retrieval

Abstract: Spend your time even for only few minutes to read a book. Reading a book will never reduce and waste your time to be useless. Reading, for some people become a need that is to do every day such as spending time for eating. Now, what about you? Do you like to read a book? Now, we will show you a new book enPDFd automatic information organization and retrieval that can be a new way to explore the knowledge. When reading this book, you can get one thing to always remember in every reading time, even step by step.

Search and Retrieval Experiments in Real-Time Information Retrieval

Abstract: Future operating document retrieval systems may be based on fully-automatic information analysis methods instead of manual indexing, and on real-time search procedures which allow the user to interact with the system during the search process. Performance characteristics are first given for fully-automatic information retrieval systems, and comparisons are made with presently operating partly-manual systems. Thereafter, various user-controlled search strategies are described, and the potential of these strategies in improving systems performance is discussed. The evaluation results for the real-time retrieval procedures are used to derive design criteria for future automatic information systems.

DATAPLUS: a language for real time information retrieval from hierarchical data bases

Abstract: To the average person, a computer user is synonymous to a programmer. In fact, to the average programmer, a user is synonymous to a programmer. Information retrieval is an area in which the computer user is not--or, at least, should not be--required to be a programmer. This paper describes a real time information retrieval system which is at once highly accessible, relatively inexpensive, and simple enough to be used by nonprogrammers.

Some mathematics of information storage and retrieval

Abstract: : The report explains some of the mathematical techniques currently being used and some which are being considered for solving a problem of information storage and retrieval. Basically two problem characterizations are discussed. The first is a statistical description and the other is a vector space characterization. Specifically, we have neglected the interesting area of linguistic analysis which is sometimes used as the basis for information retrieval. Several examples, comments and suggestions are made regarding the use of the various techniques.

Experimental evaluation of information retrieval through a teletypewriter

Abstract: Experiments designed to evaluate the capabilities of mechanized information retrieval systems, with emphasis on interactive (man-machine) language and on some of the mechanical and psychological limitations in their design, were conducted at the Moore School Information Systems Laboratory. The basic assumption of the research is that an information retrieval system that provides for man-machine dialogue at a remote inquiry terminal should provide a searcher with many of the tools which would be available to him were he actually performing his search at a library or repository of documents. Factors involved in evaluation of such a system include ease of use, learning time, and effectiveness of actual retrieval. Three experiments and the conclusions resulting from them are detailed.

A computer‐assisted flexible information retrieval system

Abstract: AS part of a policy of simplifying the indexing task in information retrieval, a system is being developed for using a computer to create indexes from a variety of styles of indexing. One of the main guiding principles in the design is ease of operation by people, both for indexing and retrieval.

Should Informal and Negative Information Get Into an Information Retrieval System

Abstract: R. ~ D. Wells, recognizing that a great deal of dependence on informal means of communication is obviously manifest in the scientific community [1], pleads also for inclusion in the information system of informal and negation reports as well as the usual flow of formal accomplishment papers which represent the establishment expression. Albeit there is sometimes tragic waste in duplication of effort on unfinished or disappointing research and evidence of demand through the resort to extensive informal communications, this does

An Interactive Document Retrieval System

Abstract: : The REQUEST document retrieval system is described. Included is a description of the data base, the interactive mode, the modular implementation in ISL--a string manipulating language, and the multiple-level Boolean hierarchy query format. (Author)

The Use of Standardized Documentary Data in Automatic Information Dissemination

Abstract: It is likely that future operating information retrieval systems may be based on automatic information analysis methods instead of manual indexing, and on search procedures which allow the user to interact with the system during the search process. The effectiveness of the required analysis and search operations depends to some extent on the availability, in machine-readable form, of standardized information concerning the make-up and content of each stored document. An author-prepared standard manuscript documentation unit, furnished with each manuscript, and illustrated in Fig. 3 of the text, may simplify the infonnation retrieval and dissemination operations and improve their effectiveness. The design of such a documentation unit is covered and its use for indexing, classification, vocabulary normalization, searching, and retrieval is explained.

TRIAL: An Information Retrieval System for Creating, Maintaining, Indexing, and Retrieving from Files of Textual Information. User's Manual.

Abstract: : TRIAL is an information processing system that will perform editing, indexing, and retrieval of textual and certain types of numeric information. The system allows for the creation and maintenance of a master file (EDIT), indexing on words designated as 'key' words or, alternatively, on every word in the text, excluding those common terms that are user supplied as a 'stop' word list (INDEX), and computer retrieval and printout of entries that satisfy a user search command (SEARCH). The system is designed such that any one or any combination of the above features can be achieved through one computer run with proper control cards. The system is especially adaptable to large masses of bibliographic data where either selective bibliographies or various forms of indexes are desired.
