Tim Berners-Lee proposed a layered architecture for the languages of the Semantic Web in 2000 and suggested an adapted architecture in 2003. We evaluated the architecture according to a list of layered architecture characteristics and in this paper, based on aforementioned evaluation, we propose an adapted layered architecture for the languages of the Semantic Web based on fundamental aspects f...

While many soft/software radio architectures have been suggested and implemented, there remains a lack of a formal design methodology that can be used to design and implement these radios. This article presents a unified architecture for the design of soft radios on a reconfigurable platform called the layered radio architecture. The layered architecture makes it possible to incorporate all of ...

Organizing a software architecture into layers has been one of the earliest architectural styles ever used. Even today layered structure is a very common architectural style used in various industrial systems. However, we have observed that the usage of layered architectural style varies greatly in different contexts. This paper aims to compare the notion of software architecture layers in rese...

Previously, we proposed a flexible two-layered speech recogniser architecture, called FLaVoR. In the first layer an unconstrained, task independent phone recogniser generates a phone lattice. Only in the second layer the task specific lexicon and language model are applied to decode the phone lattice and produce a word level recognition result. In this paper, we present a further evaluation of ...

A rather complex task in the performance analysis of software architectures has always been the interpretation of the analysis results and the generation of feedback that may help developers to improve their architecture with alternative "better performing" solutions. This is due, on one side, to the fact that performance analysis results may be rather complex to interpret (e.g., they are often...

More than two decades ago, DB researchers faced up to the question of how to design a data-independent database management system (DBMS), that is, a DBMS which offers an appropriate application programming interface (API) to the user and whose architecture is open for permanent evolution. For this purpose, an architectural model based on successive data abstraction steps of record-oriented data...

A systematic approach to building layered software architecture is proposed. Separate layering models required for a proper abstracting of hardware, persistent data, and communication protocols are described. Implications on various types of testing are discussed.
