Gulsoy, Gunhan – ProQuest LLC, 2013
New experimental methods has resulted in increasing amount of genetic interaction data to be generated every day. Biological networks are used to store genetic interaction data gathered. Increasing amount of data available requires fast large scale analysis methods. Therefore, we address the problem of querying large biological network datasets.…

Yuan, Dayu – ProQuest LLC, 2013
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.…

Steinacker, Ivo – Journal of the American Society for Information Science, 1974
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)

And Others; Prywes, Noah S. – Information Storage and Retrieval, 1974
Reports on a series of programs that have been developed to process data bases, consisting of textual items, and to index and arrange (classify) the data items in accordance with an automatically generated classification system. (Author)

Vance, David – 1974
This paper describes the process of automatic extraction of implicit--global--data from explicit information by file inversion and threading. Each datum is the symbolic representation of a proposition, and as such has a number of movable parts corresponding to the ideal elements of the proposition represented; e.g., subject, predicate. A third…

And Others; Salton, G. – Journal of the American Society for Information Science, 1975
A new technique, known as discrimination value analysis, ranks the text words in accordance with how well they are able to discriminate the documents of a collection from each other. (Author/PF)

Soergel, Dagobert – Drexel Library Quarterly, 1982
This discussion of the general principles of structure and construction of numeric databases introduces the concept of data points, their relationship to each other, and their storage in a nonredundant way. The collection of numeric data and their integration into the database structure are explained. Eight references are cited. (EJS)

Sparck Jones, K.; Van Rijsbergen, C. J. – Journal of Documentation, 1973
Substantial alterations to a system often have little or no effect on particular collections. This may be due to poor separation of relevant and non-relevant documents. The paper presents a procedure for characterizing this separation, which can show whether proposed modifications of the base system are likely to be useful. (8 references)…

Sparck Jones, Karen – Information Storage and Retrieval, 1973
Retrieval performance with automatic term classifications for three test collections has been variable. This paper attempts to discover why. The real difference between the collections is in the separation of relevant from non-relevant documents. The separation is so poor that classification cannot be expected to succeed. (14 references)…

Nicholas, David; And Others – 1975
This report is in two parts; the first part deals with a construction of a data base for bibliometric studies. The second part provides a detailed account of the results of those studies. Needs for a data base, the search for a possible candidate, and the decision to build the Check List of Social Sciences Serials (CLOSSS) are explained in the…

Sustik, Joan M.; Brooks, Terrence A. – Journal of the American Society for Information Science, 1983
Describes applications in variety of settings of videodiscs as tools of information retrieval with online databases, identifies underlying technical capabilities, and discusses five operations required to implement any application: coordinating diverse formats; indexing; physically arranging items on disc; designing input, search, and output;…

Regazzi, John J. – 1978
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…

Gaillardin, R.; And Others – 1980
This report on the multidisciplinary PASCAL database describes the files and the indexing rules for chemistry, biology, and medicine. PASCAL deals with all aspects of chemistry within two subfiles whose combined yearly growth is about 100,000 references. The Biopascal file, organized in the two subfiles of Plant Science and Biology and Medicine,…
