[en] The author proposed searching method for users who need not-comprehensive retrieval. That is to provide flexible number of related documents for the users automatically. A group of technical terms are used as search terms to express an inquiry. Logical sums of the terms in the ascending order of frequency of the usage are prepared sequentially and automatically, and then the search formulas, qsub(m) and qsub(m-1) which meet certain threshold values are selected automatically also. Users justify precision of the search output up to 20 items retrieved by the formula qsub(m). If a user wishes more than 30% of recall ratio, the serach result should be output by qsub(m), and if he wishes less than 30% of it, it should be output by qsub(m-1). The search by this method using one year volume of INIS Database (76,600 items) and five inquiries resulted in 32% of recall ratio and 36% of precision ratio on the average in the case of qsub(m). The connecting time of a terminal was within 15 minutes per an inquiry. It showed more efficiency than that of an inexperienced searcher. The method can be applied to on-line searching system for database in which natural language only or natural language and controlled vocabulary are used. (author)

[en] A computer programme for performing standardized analysis of research areas and key concepts of nuclear science and technology under development at Cubaenergia is presented. Main components of the information processing system, as well as computational methods and modules for thematic content analysis of INIS Database record files are described. Results of thematic content analysis of review Nucleus from 1986 to 2005 are shown. Furthermore, results of demonstrative study Nucleus, Science, Technology and Society are also shown. The results provide new elements to asses the significance of the thematic content of review Nucleus in the context of innovation in interrelated multidisciplinary research areas

[en] Specialized geological data model has been designed, based on which a GIS of magmatic, metamorphic and ore formations has been developed. The GIS has been developed and used for constructing the Map of magmatic, metamorphic and ore formations of the Republic of Armenia (Northern Armenia), Scale 1:300 000. Unified concept, logical, physical and geo-information models of the data of the formations map have been developed, by means of which the main concepts, attributes and their relations by hierarchical schemes have been defined. The GIS functions are based on the structure, relationships within database and additional programs for the querying and searching of spatial and attribute data, generalization and representation of results as reports. The GIS structure and relationships among its components provide an opportunity for is further development by expanding of its analytical functionalities

[en] Recently, there is a rapid development of road transportation network. This situation arises due to the number of vehicle on the road that keeps increasing year by year. Thus, this will increase the possibility of dangerous situations to the road users if roads are not being maintained appropriately. Therefore, in order to keep the road in safe condition, the road management activity should be improved. A complete system for road management has been applied in the developed countries for the past decades. However, the usage of application programming interface (API) from GIS software has limitation to make modification in terms of interactivity of the system. Open source software was proposed as a way to assist in reducing the development cost of developing road monitoring system. In this paper, open source software was proposed as a way to assist in reducing the development cost in developing road management system. OpenLayers framework was used as map rendering platform. The system can be used by administrator of road network to update the road information. At the same time, it can be used by the road user as well to view the information regarding road-related incidents

[en] Statistical properties of population to be retrieved and index terms are demonstrated experimentally with a retrieval target of 367,363 items for 5.5 years in INIS data base and 6 query formulas for a search topic. Occurrence of hits (r) in the population is assured to be a stochastic event following very close approximation to a binominal distribution function. Confidence interval for precision of the population is estimated roughly to be 0.2 -- 0.3 with a sample size of 10 < np' = r < 40 and bellow 0.2 with 40 < r < 150. Weak dependencies are observed on occurrence of index terms in the population-, hit- and noise-sets respectively by both of correlation coefficient and expected mutual information measure. It is confirmed for this weakness that the dependency is right in principle for the occurrence but independency is also a justifiable assumption. Ranking performance of the population is affected by a sample size for weight generation. While a size of np' = r > 10 has a favourable influence upon the performance, a size of r < 10 doesn't produce any performance. Those data should be beneficial to creation and evaluation of various ranking schemes. (author)

[en] The structure is described of Revision 16 of the INIS Thesaurus containing 15,674 descriptors and 4534 non-descriptors (forbidden terms). The mutual relationships are explained of the Thesaurus terms, such as preference, hierarchy, association. Figures on frequencies of usage are shown for each descriptor; for all descriptors included after 1st July 1975 the numbers are completed with the date of inclusion in the Thesaurus. Document indexing is described in detail and basic principles for use and coordination of descriptors are shown. The Thesaurus is also used for compiling the subject index of the INIS-Atomindex journal and, since 1979 also for indexing numerical data. In order that consistency should be retained in document indexing within IAEA dispite the decentralized input material processing by INIS, two manuals for indexers have been issued, input materials are checked, training seminars are held and special indexing consistency tests are conducted.

[en] Depicts the nature and operations of the first truly international, decentralized and computerized information processing and dissemination system, INIS. The products of the system, consisting of various literature indexes issued in both printed form and on magnetic tapes are described and their utility to scientists is demonstrated

[en] Systems that allow users to store and retrieve spatial data, provide for analyses of spatial data, and offer highly detailed display of spatial data are referred to as geographic information systems, or more typically, GIS. Since their initial usage in the 1960s, GISs have evolved as a means of assembling and analyzing diverse data pertaining to specific geographical areas, with spatial locations of the data serving as the organizational basis for the information systems. The structure of GISs is built around spatial identifiers and the methods used to encode data for storage and manipulation. This paper examines how GIS has been used in typical environmental assessment, its use for cumulative impact assessment, and explores litigation that occurred in the United States Federal court system where GIS was used in some aspect of cumulative effects. The paper also summarizes fifteen case studies that range from area wide transportation planning to wildlife and habitat impacts, and draws together a few lessons learned from this review of literature and litigation.
