Semantic Web Science Association 

Semantic Web Science Association: "Objectives

The Semantic Web Science Association (SWSA) is a non-profit organisation incorporated in Karlsruhe, Germany for the purpose of promoting and exchanging scholarly work in Semantic Web and related fields throughout the world. The association's activities are selfless; its main objectives do not concern any own economic interests."

OntoWiki: Community-driven Ontology Engineering and Ontology Usage based on Wikis 

OntoWiki: Community-driven Ontology Engineering and Ontology Usage based on Wikis
Martin Hepp, Daniel Bachlechner, Katharina Siorpaes
Ontologies are consensual representations of a domain of discourse and the backbone of the future Semantic Web. Currently, however, only a fraction of Web users can take part in the process of building ontologies. In this paper, we show that standard Wiki technology can be easily used as an ontology development environment, reducing entry barriers for the participation of users in the creation and maintenance of ontologies, and describe our first OntoWiki prototype."

Self-organization and Language Evolution: System, Population and Individual 

Self-organization and Language Evolution: System, Population and Individual (large .PDF)
Jinyun Ke
This thesis proposes a framework adopting the self-organization theory for the study of language evolution. Self-organization explains collective behaviors and evolution with the observation that the patterns at the global level in a complex system are often properties spontaneously emergent from the numerous local interactions among the individual components, and they cannot be understood by only examining the individual components.

Language can be viewed as such emergent properties instead of products from some innate blueprint in humans. We highlight the importance of recognizing language at two distinctive but inter-dependent levels of existence, i.e. in the idiolect and in the communal language, and a self-organizing process existing at each of the two levels. It is necessary to clarify what phenomena are properties of the idiolects, and what properties are the collective behaviors at the population level."

The Impact of Semantic Handshakes 

The Impact of Semantic Handshakes
Lutz Maicher
"One of the key challenges for the breaking through of the semantic web or web 2.0 is global semantic integration: if two proxies in different models represent the same thing in the “real world” they should become mergeable. The common top-down approach to semantic integration is the enforcement of centralised ontologies or PSI repositories. This top-down approach bases on a overly optimistic premise: the success of one universal vocabulary enforced by a central authority. This paper proposes a bottom-up approach. A semantic handshake is the decision that two terms from different vocabularies can be used to identify the same “thing”. If these local decisions are broadcasted, global integration can be achieved without any ontological imperialism. Within this paper this hypothesis is investigated by simulations. We show that if the majority of proxies describes its identity only by two different public known terms, global integration is almost achievable at the large scale."

Automated Collaboration on the Semantic Web 

Automated Collaboration on the Semantic Web
Michael Stollberg, Thomas Strang, Dieter Fensel1
"Abstract. We understand the vision of the Semantic Web to proclaim seamless and automated collaboration of the Internet. Collaboration is concerned with cooperative interaction of individuals in order to achieve complex objectives; appropriate technologies for collaboration support need to reflect the nature of collaboration, and to comply with several technical requirements with respect to automated and semantically enabled collaboration support. This paper presents a framework for collaboration support on the Semantic Web that coherently integrates agent technology, ontologies, and Semantic Web services."
"6 Conclusions
This paper has summarized the approach and core aspects of a framework that coherently integrates agents, ontologies, and Semantic Web services for automated collaboration support on the Semantic Web. Collaboration is concerned with cooperative interactions of individuals in order to achieve complex objectives. Understanding automated collaboration support as the essential functionality of the Semantic Web, we have examined the inherent characteristics of collaboration from related academic disciplines as the conceptual basis for properly integrating the key technologies identified for the Semantic Web. ...

Semantics in Business Information Systems (SEBIS) 

Semantics in Business Information Systems (SEBIS): "Semantics in Business Information Systems (SEBIS)

Business Information Systems (BIS) as a discipline addresses research questions resulting from the use of computer systems for business purposes. While its historical roots are proprietary and monolithic systems designed for the automated processing of mass transactions, the overall trend of the past decade has been a shift towards (1) a complex environment consisting of a grown combination of legacy systems and large, common-of-the-shelf application (COTS) packages (e.g. ERP libraries), (2) the organization-wide diffusion of IT into all kinds of business and service processes, and (3) the need to support automated interactions with a multiplicity of partners at various levels of detail. This has dramatically increased the complexity of managing IT use in business."

"Research Interests: My major research interest is Semantics in Business Information Systems, especially the use of ontologies for advancement in the automation of all steps in the life-cycle of business processes. Ontologies in my understanding are community contracts about a representation of a domain of discourse.
Representation in here includes (1) formal parts that can be used for machine reasoning, and (2) informal parts like natural language descriptions and multimedia elements that help humans establish, maintain, and renew consensus about the meaning of concepts. In my opinion, both aspects of ontologies are equally important, and I watch the current dominance of the formal aspects of ontologies in academic research with unease."

Language Acquisition: Do as You Hear 

Language Acquisition: Do as You Hear
Hugo Théoret and Alvaro Pascual-Leone
"It is not uncommon to recognize a specific action by the sound it creates. Neurons have been discovered in monkey premotor cortex that may contribute to this ability; they respond to both performing an action and hearing its action-related sound, and may be critical for communicating with others, learning gestures and even acquiring language."
