However, manual requirements conflict analysis takes significant effort and is error-prone. Requirement engineers and other project participants such as technical architects use different terminologies (due to different domain backgrounds) which makes automation of conflic...

Introduction Conflict often leads to nonequilibrium fluctuations as attackers spread, host defences increase, and counter-attack evolves. Spatial processes play a crucial role when attack types arrive from other populations and import of matching defence follows. We focus on cytoplasmic male sterility (CMS), an ideal system in which to study the spatial dynamics of conflict. Cytoplasmically inh...

The question we consider in this paper is what benefits we can derive from paying attention to such object semantics, particularly for the problem of keyword queries. Keyword queries against XML data have been studied extensively in recent years, with several lowest-common-ances...
