Conformal Weyl and Cotton tensors are dimensionally reduced by a Kaluza– Klein procedure. Explicit formulas are given for reducing from four and three dimensions to three and two dimensions, respectively. When the higher dimensional conformal tensor vanishes because the space is conformallly flat, the lower-dimensional Kaluza–Klein functions satisfy equations that coincide with the Einstein–Wey...

One of the most effective means for re-establishing trust in negotiations and disputes is by making an apology. However, the function and meaning of an apology (and thus its effectiveness for negotiators) may differ across cultures. We hypothesized that people from an individual-agency culture (such as the United States) understand apologies as analytic mechanisms for assigning blame and re-est...

Efficient agent communication in open and dynamic environments relies on the agents ability to reach a mutual understanding over message exchanges. Such environments are characterized by the existence of heterogeneous agents that commit to different ontologies, with no prior assumptions regarding the use of shared vocabularies. Various approaches have therefore considered how mutually acceptabl...

For the past two decades linguists working within the framework of systemic functional linguistics have been developing appraisal theory as a tool for analysing evaluation in discourse. In this talk I will present a brief overview of the current model and then move on to address a number of the challenges that have arisen over the years including distinguishing inscribed from invoked attitude, ...

In this paper, we explore the process of interorganizational ontology engineering. Scalable ontology engineering is hard to do in interorganizational settings where there are many pre-existing organizational ontologies and rapidly changing collaborative requirements. A complex socio-technical process of ontology alignment and meaning negotiation is therefore required. In particular, we are inte...

This paper reports a 3-month study investigating engineering students’ Communication Strategies (CSs) in a mobile-assisted course. 67 Chinese learners of English in this course volunteered to participate in the study. The instruments included oral communication sessions, stimulated recall interviews, WeChat exchanges, etc. Results showed that the participants used a variety of CSs when completi...

We address the problem of semantic coordination, namely finding an agreement between the meanings of heterogeneous semantic models. We propose a new approximation method to discover and assess the “strength” (preciseness) of semantic mappings between concepts from different concept hierarchies. We apply this method in the music domain. We present the results of preliminary tests on mapping two ...

The Internet globally connects a great deal of diverse and heterogeneous information resources, which an agent can dynamically combine in order to synthesise new information. An agent society is used to facilitate a common project within globally distributed, heterogeneous organisations. Besides coordinating a finite number of variables, the agents are used to iron out cultural differences with...
