Abstract

The idea of conceptual mapping goes back to the semantic differential and conceptual clustering. Using multivariate statistical techniques, one can map a dispersion of texts onto another dispersion of their content indicators, such as keywords. The resulting configurations of texts/indicators differ from one another according to their meaning, expressed in terms of co‐ordinates of a semantic field. We suggest that by using principal component analysis, one can design a user‐friendly semantic space which can be navigated. Further, to learn the names of embedded magnitudes in semantic space, the idea of conceptual clustering is used in a broader context. This is a two‐mode statistical approach, grouping both documents and their index terms at the same time. By observing the agglomerations of narrower, related terms over a corpus, one arrives at broader, more general thesaurus entries which denote and conceptualise the major dimensions of semantic space.

Abstract

In the former Yugoslavia and Soviet Bloc countries of Central and Eastern Europe most information technology was unavailable, unaffordable or discouraged for forty years. These countries realise that they must improve their internal infrastructures if they are to become integral parts of the global information infrastructure. We report the results of a mail survey conducted in late 1994 and early 1995 of seventy research libraries in Croatia, Czech Republic, Hungary, Poland, Slovakia and Slovenia, building on the findings from interviews conducted with 300 persons in the region in 1993–1994. Results show that these libraries are acquiring automated processing systems, CD‐ROM databases, and connections to computer networks at a rapid rate and that automation activity has increased substantially since 1989; we report specific data on system implementation and network services by country and by type of library. ‘Access’ is their top reason to automate, which appears to mean placing the catalogue online with better search capabilities and putting items on the shelves faster — but does not necessarily mean improvements in self‐service for library users. Co‐operation and standards are highly‐ranked automation goals, yet we find anomalous results on each. Management goals focus more on speed and processing than on management information, staffing or advancing the mission of the parent organisation. Management of human resources ranks low, despite the need for wider staff involvement in the system selection process, education of technically‐trained library professionals, continuing training of staff and training of library users. We conclude with implications of these results for the region.
