Investigates the feasibility of using a distance measure for automatic sequential document classification. This property of the distance measure is used to design a sequential classification algorithm which classifies key words and analyzes them separately in order to assign primary and secondary classes to a document. (VT)

The study has applied speech recognition and text-mining technologies to a set of recorded outbound marketing calls and analyzed the results. Since speaker-independent speech recognition technology results in a significantly lower recognition rate than that found when the recognizer is trained for a particular speaker, a number of post-processing…

Problems encountered in converting a card-oriented biological data information system to new computer equipment are discussed. Data formats, input-output procedures, search strategies, etc., are described. (5 references) (Author/SJ)

The formation of a single, correlated set of data elements, accomplished by merging sixteen commercial and national bibliographic data bases, and subsequent improvements in current awareness and information retrieval activities are described. The correlation is compatible with most existing and proposed data-element standards. (27 references)…

The major topics included in this paper are: thesaurus structure, later developments, functions of thesauri, keyword list generation, compatibility, and maintenance and updating. (NH)

It is shown that this new automatic indexing technique can be applied with the same effectiveness shown earlier for indexes derived from words in titles or title-like phrases; the basic difference being that linear notation symbols rather than words are used as the indexing units. (17 references) (Author/NH)

The authors found great discrepancies in the presentation of essentially similar bibliographic data, and offer some suggestions for mitigating the discrepancies by use of standards. (Author)

The American Institute of Physics Current Physics Information program offers new products to help scientists and engineers stay up to date, including a computer tape file and microfilm cartridge of selected articles. Later additions will include title, advance abstracts and bibliographic publications. (TS)

Presents a new method to improve the performance of query processing in a spatial database. Experiments demonstrated that performance of database systems can be improved because both the number of objects accessed and number of objects requiring detailed inspection are much less than those in the previous approach. (AEF)

Uses Kintsch's proposition-based construction-integration theory of discourse comprehension to detail the user coding operations that occur in each of the three subsystems (Perception, Comprehension, Application) in which users process an information retrieval systems (IRS) message. Describes an IRS device made up of two separate parts that enable…

Presents an approach for dynamic database integration and query processing in the absence of information about attribute correspondences and global IDs. Defines different types of equivalence conditions for the construction of global IDs. Proposes a strategy based on ranked role-sets that makes use of an automated semantic integration procedure…

Describes a simple computer-based information retrieval system which manipulates non-numeric information using a program that simulates a three-level information storage system. The system is used to create, modify, and selectively search a data base both interactively and noninteractively. (MLH)

Designed to minimize information overload in telecommunications systems, the formal model developed in this paper predicts the usefulness of a message based on the available message features, and may be used to rank messages by expected importance or economic worth. The assumptions of binary and two Poisson independent probabilistic distributions…

WISE is an on-line interactive information retrieval system designed to operate on keyword oriented data bases. The system was designed particularly with bibliographic data bases in mind, but it is potentially useful for any keyword oriented data base. The WISE user searches a data base by entering and combining keywords that are appropriate to…
