- Abstract
- Presents the basic ideas underlying fuzzy set theory, developed by Zadeh in the 1960s, which has important appplications in information retrieval and documentation. A fuzzy information retrieval system is much less restrictive that a Boolean model, since results can be arranged according to degree of similarity. Another application of the theory concerns the use of linguistic quantifiers; this type of solution is well adapted to retrieval systems designed for direct operation by end-users. Illustraes with examples fuzzy set algebra, operation, relationships, logic and reasoning

- Replies to some criticisms of the GADA (Manuale per la gestione automatizzata delle descrizioni archivistiche / Archival Descriptions Automation Handbook) the archival theory underlying it, and GADA's application in CDS/ISIS. Discusses the relationship between library, archival and information science; archival search via topics/subjects as well as by institution; and the relation between the ISAD(G) descriptive standard and MARC AMC. Reviews the impact of computers on archival theory and practice

- Abstract
- Library science may well have an essential role to play in efficiently organising the huge amount of Internet information available in the various scientific disciplines. The basic problem is to develop a cataloguing theory sufficiently flexible to cope with the impact of an ever changing store of network data. Such a theory would abondon the utopian idea of a 'catalogue of ctalogues', seeking instead to match each specific user query to the most appropriate catalogue. Examines 2 important USA projects for cataloguing network resources: Digital Libraries Research (funded by the National Science Foundation), which uses a combination of search engines to retrieve net data; and the Internet Public Library. Lists the Management and Library Schools now on the WWW

- Abstract
- Proposes a new experimental methodology for evaluating the results of library research from the user's viewpoint. Illustrates the theory by comparing the efficacy of information retrieved from 2 document catalogues, identical except that one is alphabetical and the other numerical/verbal. The methodology utilises the concept of 3 dependent variables: 'promising references retrieved' by the researcher; 'documents read'; and 'documents cited'. Claims that the retrieval effectiveness of the techniques outlined compares favourably with that of W.S. Cooper's methodology

- Abstract
- In relation to indexing, one of the chief implications of cognitive epistemology is the necessity for redefining knowledge representation concepts for information filing and retrieval purposes. Such a redefinition involves abandoning the traditional, hierarchical, closed-structure classification model. Considers the following in detail: a semiotic critique of classification principles; Ranganathan's classification theory; Ranganathan and cognitive epistemology; and some reflections on the DDC and the Bliss Bibliographic Classification

- Abstract
- The article illustrates briefly the principles at the basis of the theory of science and the universal system conceived. Ingetraut Dahlberg occupa un posto di primo piano in Documentazione per le iniziative importanti che ha realizzato e per l'apporto teoretico fornito all'ordinamento conoscenze. Critica sulle possibilità di sviluppo degli attuali sistemi di classificazione universale, fondati per paradigmi storico-filosofici su discipline, Dahlberg introduce una teoria concettuale rivolta all'organizzazione del singolo campo di conoscenza e del sapere universale. L'articolo espone brevemente i principî che sono alla base della teoria e del sistema universale concepito.

- A reprint of the introduction to Vol.IX of the author's 'History of Bibliography' (Storia della Bibliografia). Cites K. Popper's theory of the 3 worlds of reality, i.e the natural world; subjective experiences; and recorded information; arguing that over the past 50 years bibliography has been relegated to dealing with researches that relate to the 2nd world and has thus lost its true scientific character. We should restore to bibliography the attributes deriving from its roots and from its links with the 3rd world, so that it can be applied directly to the architectue of general semantics, which related both to ideas and documents

- Abstract
- Looks at current research into the cognitve aspects of information search and retrieval by library users. Illustrates the theoretical approach to indexing procedures, developed from a cognitive viewpoint, and outlines the basics of cognitive epistemology. Discusses the work of psychologist W. Kintsch and linguist T.A. van Dijk on the mechanics of information acquisition, text comprehension and text production. Analyses the linguistic theory of meaning, and summarises the main criticisms of the cognitive approach, as propounded by B. Frohmann, B.C. Brookes, R.L. Derr and D. Rudd, among others

- Rez. in: Knowledge organization 34(2007) no.1, S.58-60 (P. Buizza): "This Nuovo soggettario is the first sign of subject indexing renewal in Italy. Italian subject indexing has been based until now on Soggettario per i cataloghi delle biblioteche italiane (Firenze, 1956), a list of preferred terms and see references, with suitable hierarchical subdivisions and cross references, derived from the subject catalogue of the National Library in Florence (BNCF). New headings later used in Bibliografia nazionale italiana (BNI) were added without references, nor indeed with any real maintenance. Systematic instructions on how to combine the terms are lacking: the indexer using this instrument is obliged to infer the order of terms absent from the lists by consulting analogous entries. Italian libraries are suffering from the limits of this subject catalogue: vocabulary is inadequate, obsolete and inconsistent, the syndetic structure incomplete and inaccurate, and the syntax ill-defined, poorly explained and unable to reflect complex subjects. In the nineties, the Subject Indexing Research Group (Gruppo di ricerca sull'indicizzazione per soggetto, GRIS) of the AIB (Italian Library Association) developed the indexing theory and some principles of PRECIS and drew up guidelines based on consistent principles for vocabulary, semantic relationships and subject string construction, the latter according to role syntax (Guida 1997). In overhauling the Soggettario, the National Library in Florence aimed at a comprehensive indexing system. (A report on the method and evolution of the work has been published in Knowledge Organization (Lucarelli 2005), while the feasibility study is available in Italian (Per un nuovo Soggettario 2002). Any usable terms from the old Soggettario will be transferred to the new system, while taking into consideration international norms and interlinguistic compatibility, as well as applications outside the immediate library context. The terms will be accessible via a suitable OPAC operating on the most advanced software.
