The Web information retrieval is a highly popular, but also a challenging research area, which considerably differs from the classical information retrieval theory. The focus of this paper is to survey the modern approaches to the accomplishment of d

In this paper, the problem of automatic document classification by a set of given topics is considered. The method proposed is based on the use of the latent semantic analysis to retrieve semantic dependencies between words. The classification of doc

The problem of developing an intelligent Internet search engine for creating topic-specific collections is considered. To improve the efficiency of discovering topic-related resources, a specialized network crawling algorithm is developed that uses i

Semistructured data models provide an important tool for studying methods for representing, searching, and processing heterogeneous data in distributed systems with autonomous components (especially, on the WWW). However, the problem of data consiste

Although the major source of semistructured data is WWW and therefore the representation of data cannot be controlled by any single site, in many cases the data are replicated and stored locally in a database to support sophisticated query processing

As part of the OASIS project, an autonomous intelligent agent, called an OASIS Crawler, was designed to address the problem of automatically constructing topic-specific Internet indices. Each OASIS Crawler independently constructs an index of Interne

An implementation of persistent object store for real-time systems with strict processing time constraints is a challenging task, because many traditional database techniques, e.g. transaction management schemes, are not applicable for such systems.

In this paper we consider real-time concurrency control for the nested transactionmodel. We analyze problems that have pure optimistic and pessimistic approaches. As the solution we propose a hybrid concurrency control algorithm which acts as an opti
