An experiment: search strategy variations in SDI profiles
نویسنده
چکیده
This research project was one of a number concerned with mechanized information retrieval carried out at INSPEC and supported by grants from, originally, the Department of Education and Science's Office for Scientific and Technical Information (OSTI) and, later, the British Library Research and Development Department (BLRDD). The first project, in the period 1967-69, had investigated the performance, economics and acceptability to users of a computerized SDI service in electronics. As a result of this study, in 1970 INSPEC offered publicly an SDI service in electronics. Another research project, overlapping the SDI investigation, had established the comparative effectiveness of natural language as a medium for mechanized searching so that, from 1971, all documents input to the INSPEC database were assigned free

Investigation of Genetic Variations among Crested Wheatgrass Species Base of Agronomical Traits and Total Leaf Protein
Genetic variations within the species of Agropyron desertorum and 2 varieties of A. cristatum subsp. pectinatum var. imbricatum and A. cristatum subsp. pectinatum var. pectinatum were studied using morphological traits and total protein profiles (with sodium dodecylsulphate polyacrylamide gel electrophoresis). An experiment was conducted in Research Institute of Forests and Rangelands (2012-201...
متن کاملA Monte Carlo-Based Search Strategy for Dimensionality Reduction in Performance Tuning Parameters
Redundant and irrelevant features in high dimensional data increase the complexity in underlying mathematical models. It is necessary to conduct pre-processing steps that search for the most relevant features in order to reduce the dimensionality of the data. This study made use of a meta-heuristic search approach which uses lightweight random simulations to balance between the exploitation of ...

This paper presents the Multi-view assessment of SDI status in the Republic of Kosovo performed in 2007 and in 2010. The main objective of this research was to assess the SDI of Kosovo and to define the driving forces needed to support SDI strategy development. The research assesses the status of SDI implementation of Kosovo using SDI readiness Index (Delgado et al., 2005); INSPIRE State of Pla...
متن کاملScaling SDI Systems via Query Clustering and Aggregation
XML-based Selective Dissemination of Information (SDI) systems aims to quickly deliver useful information to the users based on their profiles or user subscriptions. These subscriptions are specified in the form of XML queries. This paper investigates how clustering and aggregation of user queries can help scale SDI systems by reducing the number of document-subscription matchings required. We ...
متن کاملThe Comparison of Survival Rates between Narrow Diameter Implants and Standard Diameter Implants: An Updated Meta-analysis
Background: One of the key objectives is to update knowledge in order to develop treatment and care recommendations based on research findings. The purpose of the present meta-analysis was to compare the survival rate of narrow dental implants (NDI) with standard dental implants (SDI). Methods: The international databases targeted for conducting a broad search included PubMed (Medline), Sco...
