对开展二次文献服务的探讨

文献按加工层次通常划分为:零次文献、一次文献、二次文献、三次文献。所谓二次文献是指:按照一定的原则、方法对一次文献(即首次发表的原始文献)进行加工、整理而成的、用于揭示和报道一次文献的文献。比如常见的书目、题录、索引、文摘及专题汇编等。二次文献更便于查找、利用一次文献,具有工具性、检索性和报道性的特点。

The status of a document

The question about the status of a document follows from the situation that has been established in modern science, where the concept of a “document” has lost any definiteness and the phenomena of the reality that it means have almost no boundaries in their diversity. What material objects are documents and what are not? This question still remains debatable. This question can be answered by introducing the concept “status of a document” into the categorical apparatus of document science. The goal of this paper is to conceptualize this idea.     

The features of a document

The essence of a document, like of any other object (thing), is its features, properties, and functions. In works that are devoted to document theory no clear-cut boundaries between these notions are visible; the purpose of this paper is to coordinate them and to define a document??s essential features as an information object and is a social phenomenon.

General document and book theory

The vast documentologic study materials in the Russian and English languages have been supplemented by a manual by G.N. Shvetsova-Vodka The General Document and Book Theory simultaneously issued in Moscow and Kiev. The author is a well-known Ukrainian scientist and a professor in the library science and bibliography department of the Rovno State Humanitarian University who has published many valuable scientific and educational books, as well as other works in the field of documentation science, bibliology, and bibliography science.     

Evolutionary learning of document categories

This paper deals with a supervised learning method devoted to producing categorization models of text documents. The goal of the method is to use a suitable numerical measurement of example similarity to find centroids describing different categories of examples. The centroids are not abstract or statistical models, but rather consist of bits of examples. The centroid-learning method is based on a Genetic Algorithm for Texts (GAT). The categorization system using this genetic algorithm infers a model by applying the genetic algorithm to each set of preclassified documents belonging to a category. The models thus obtained are the category centroids that are used to predict the category of a test document. The experimental results validate the utility of this approach for classifying incoming documents.     

The functions of a document

The essence of a document, like any other object (thing), manifests itself through its signs, properties, and functions. The works that are devoted to the problems of document theory do not trace clear boundaries between these concepts, owing to which it is necessary to unify them. The goal of this paper is to perform a functional analysis of a document as an information object and social phenomenon.
