This paper reports on the design, development and evaluation of a buffer algorithm named RESBAL, which exploits parallelism in order to provide high query execution performance in relational database systems. The algorithm aims to provide both predictive and efficient data buffering by exploiting th

โฆ Synopsis
The increasing acceptance of database systems has shown the need for logical database design methodologies and evaluation criteria to select the one most appropriate for a particular task. Application of currently existing methodologies to a portion of the data handled during chemical process plant design has highlighted strengths and shortcomings of the methodologies analysed. Using these results, evaluation criteria are established and synthesis of a methodology which is responsive to the identified criteria is proposed.

## Abstract The authors describe a statistical approach based on hidden Markov models (HMMs), for generating stemmers automatically. The proposed approach requires little effort to insert new languages in the system even if minimal linguistic knowledge is available. This is a key advantage especial
This work describes a new methodology for making easier the design process of interpretable knowledge bases. It considers both expert knowledge and knowledge extracted from data. The combination of both kinds of knowledge is likely to yield robust compact systems with a good trade-off between accura
