In this paper, we present a new extreme learning machine network structure on the basis of tolerance rough set. The purpose of this paper is to realize the high-efficiency and multi-dimensional ELM network structure. Various published algorithms have been applied to breast cancer datasets, but...

Abstract The Great Recession in Germany was noticed only seven months after its onset. This study examines whether the available data could have helped to predict or identify the crisis in real time. After assessing the accuracy of previous recession forecasts, we examine that of forecasts...

This article presents a novel user‐oriented interface for generalised informetric analysis and demonstrates how informetric calculations can easily and declaratively be specified through advanced data modelling techniques. The interface is declarative and at a high level. Therefore it is easy...

This paper outlines the evolution of World Wide Web protocols. The paper reviews the original protocols developed for the web, in addressing, transport and data formats. A review of developments of the protocols is given, including developments of web data formats (HTML 4.0, cascading...

This paper provides an introduction to the use of n ‐grams in textual information systems, where an n‐gram is a string of n , usually adjacent, characters extracted from a section of continuous text. Applications that can be implemented efficiently and effectively using sets of n ‐grams...

A user who makes repeated use of a retrieval system may be assumed to have a context which is common to successive uses (even if the immediate need differs). An IR system which could make use of this context may be better able to match the specific need. A machine‐learning approach to...

Due to the economic and strategic importance of telecommunication services, as well as projected growth rates in the information industries, countries have adopted policy restrictions on transborder data flows (TBDF) both into and out of their countries. The reasons for these measures include...

A number of important questions face top managers in all areas of business concerning the growth and use of computers. Outlines, based on the composite experience of a number of companies, a mission for Information Systems Services (ISS). Investigates important trends impacting on the provision...

Almost all Government Departments are currently involved in major information technology (IT) projects. All have set objectives, but the true impact on the Departments is often unclear. The different IT systems being introduced are considered, along with the issues they raise. The implications...

Investigates the medical factors affecting the reliability of artificial heart valves using the proportional hazards model. The data, from a database which is still being assembled at Killingbeck Hospital, Leeds, refer to patients who have had artificial heart valves implanted. The analysis of...
