Object-Relational Database Representations for Text Indexing
One of the distinctive features of Information Retrieval systems comparing to Database Management systems, is that they offer better compression for posting lists, resulting in better I/O performance and thus faster query evaluation. In this paper, we introduce database representations of the index that reduce the size (and thus the disk I/Os) of the posting lists. This is not achieved by redes...
متن کاملA Database Model for Medical Consultation
The database model presented in this paper is suitable for application in which queries may require non-crisp references to certain attributes. The data item (attribute) values may be crisp or fuzzy. For instance, such adjectives as 'high' or 'normal' may be attribute values for the attribute blood pressure. A disease or a condition can be described by a number of symptoms which may be crisp al...
متن کاملTowards a Fuzzy Object-Relational Database Model
This chapter introduces a fuzzy object-relational database model including fuzzy extensions of the basic object-relational databases constructs, the user-defined data types, and the collection types. The fuzzy extensions of these constructs focus on two main flexible aspects, a way to flexibly compare complex data types and an extension of collection types allowing partial membership of its ele...
متن کاملA Relational Neural Network Database Model
In this paper a framework for the conceptual and physical integration of neural networks into rela-tional database systems is presented. The neural network 'meta model', as the neural network paradigms, the static and dynamic properties, and the pattern description, is realized by a collection of relations and dependencies between them. The speciic network objects (the 'ortho' networks) are tup...
