Graphs are widely used to model structures and relationships of objects in various scientific and commercial fields. Chemical molecules, proteins, malware system-call dependencies and three-dimensional mechanical parts are all modeled as graphs. In this dissertation, we propose to mine and index those graph data to enable fast and scalable search.…

The use of a structured system of storing information, particularly relational indexing, can lead to situations in which items would not be retrieved due to technicalities of the system. To overcome such problems a study was made of condensations with the aim of providing a series of rules to apply. (4 references) (Author/SJ)

Present day shortcomings in information retrieval are the results of a failure to properly contend with the problem of data representation. The index provides the necessary linkage between a multiplicity of sources and a single receiver. Whether considering the source/document-space interface or the query/index interface, the elements of the…

Use of syntactic trace as an access strategy for large files containing arbitrary languages for which thesaurus-based and multiple attribute search techniques are unsuitable. (LS)

The indexing and online searching of data bases have both conflicting and complementary structures, determined in part by the choice of indexing language. In the planning of a machine readable system, the Foundation Center, administrator of two data bases, initially chose a natural language for the lower cost, more rapid implementation, and…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

An experimental procedure for indexing physical materials based on simple syntactical rules was tested by encoding the materials in the journal, Applied Physics Letters,'' to produce a materials index. The syntax and numerous examples together with an indication of the method by which retrieval can be effected are presented. (5 references)…

A study was conducted to determine the most effective way to organize the data that are being accumulated by the European Documentation and Information System for Education (EUDISED). The study considered types of information services and search facilities which might be used to access the EUDISED data base. Indexing systems were examined and…

Three specific contributions to the field of information retrieval are presented. The first two describe the establishment of an adaptive, interactive man-machine dialogue that produces a form of unsolicited librarian-like assistance for the user in his selection of index terms to characterize an indexing function. The data set upon which the…

A THESAURUS OF EDUCATIONAL TERMS WAS PRODUCED TO PROVIDE A TERMINOLOGY BASE WHICH WOULD BE AMENABLE TO RAPID AND EASY MODIFICATION AND UPDATING. THE PRIMARY SOURCE OF TERMS WAS A SEMANTIC CODE DICTIONARY, PREVIOUSLY CREATED DURING THE INDEXING OF SOME 6,500 EDUCATIONAL RESEARCH DOCUMENTS. A FACETED STRUCTURE WAS CREATED. THE DISPLAY CONSISTED OF…

An algorithm is proposed to solve the problem of sequential indexing which does not use any grammatical or semantic analysis, but follows the principle of emulating human judgement by evaluation of machine-recognizable attributes of structured word assemblies. (Author)

Deals with the relationship between a theory of indexing and a theory of information storage and retrieval. Attention is directed to the view that indexing is an order increasing operation, and some thermodynamic notions are invoked to aid in this description. (MF)

Indexing and abstracting can be thought of as a way of modeling an actual document or textual item. Both are miniature versions of the actual thing. Normally, the indexing model is used to locate desired information, while the abstracting model is used as a screening medium to help the searcher decide which of the apparently correct actual items…

Proposes a new conceptual basis for visualizing the organization of information, or knowledge, which differentiates between the concept "vectors" for a field of knowledge represented in a multidimensional space, and the state "vectors" for a person based on his understanding of these concepts, and the representational…
