Contribution to a special section devoted to full text inf retrieval. Investigates the nature of the relationship existing between: the levels of inter hypertext link consistency in full text databases of earlier experiments, and the levels of effectiveness of a number of searches carried out in those databases. Describes the implementation of the searches and the methods used in the calculation of numerical values expressing their effectiveness. Analysis of the results of a comparison between recorded levels of consistency and those of effectiveness does not allow us to draw conclusions about the consistency-effectiveness relationship that are equivalent to those drawn in comparable studies of inter-indexer consistency.

The technological revolution is affecting the structure, form and content of documents, reducing the effectiveness of traditional abstracts that, to some extent, are inadequate to the new documentary conditions. Aims to show the directions in which abstracting/abstracts can evolve to achieve the necessary adequacy in the new digital environments. Three researching trends are proposed: theoretical, methodological and pragmatic. Theoretically, there are some needs for expanding the document concept, reengineering abstracting and designing interdisciplinary models. Methodologically, the trend is toward the structuring, automating and qualifying of the abstracts. Pragmatically, abstracts networking, combined with alternative and complementary models, open a new and promising horizon. Automating, structuring and qualifying abstracting/abstract offer some short-term prospects for progress. Concludes that reengineering, networking and visualising would be middle-term fruitful areas of research toward the full adequacy of abstracting in the new electronic age |

The question "What is a digital document?" is seen as a special case of the question "What is a document?" Ordinarily the word "document" denotes a textual record. Early this century, attempts to provide access to the rapidly growing quantity of available documents raised questions about which should be considered a "document". Paul Otlet and others developed a functional view of "document" and discussed whether, for example, sculpture, museum objects, and live animals, could be considered to be "documents". Suzanne Briet equated "document" with organized physical evidence. These ideas resemble notions of "material culture" in cultural anthropology and "object-as-sign" in semiotics. Others, especially in the USA (e.g. Jesse Shera and Louis Shores) took a narrower view. Old confusions between medium, message, and meaning are renewed with digital technology because technological definitions of "document" become even less realistic when everything is in bits (AU) |
