Exploiting Deep Semantics and Compositionality of Natural Language for Human-Robot-Interaction
We develop a natural language interface for human robot interaction that
implements reasoning about deep semantics in natural language. To realize the
required deep analysis, we employ methods from cognitive linguistics, namely
the modular and compositional framework of Embodied Construction Grammar (ECG)
[Feldman, 2009]. Using ECG, robots are able to solve fine-grained reference
resolution problems and other issues related to deep semantics and
compositionality of natural language. This also includes verbal interaction
with humans to clarify commands and queries that are too ambiguous to be
executed safely. We implement our NLU framework as a ROS package and present
proof-of-concept scenarios with different robots, as well as a survey on the
state of the art

A conceptual model for semantically-based e-government portals
Issues of semantic interoperability and service integration for e-government portals are the domain of interest of the present paper. We propose a Conceptual Model for One-Stop e-Government Portals based on the Semantic Web Service technology. We describe our research into building the three basic ontologies and their integration with standard ontologies. The result is a project-independent reusable model. At the same time, we outline a simple methodology for applying the proposed conceptual model into a specific scenario
Reflexive transnational law : the privatisation of civil law and the civilisation of private law
The author examines the emergence of a transnational private law in alternative dispute resolution bodies and private norm formulating agencies from a reflexive law perspective. After introducing the concept of reflexive law he applies the idea of law as a communicative system to the ongoing debate on the existence of a New Law Merchant or lex mercatoria. He then discusses some features of international commercial arbitration (e.g. the lack of transparency) which hinder self-reference (autopoiesis) and thus the production of legal certainty in lex mercatoria as an autonomous legal system. He then contrasts these findings with the Domain Name Dispute Resolution System, which as opposed to Lex Mercatoria was rationally planned and highly formally organised by WIPO and ICANN, and which is allowing for self-reference and thus is designed as an autopoietic legal system, albeit with a very limited scope, i.e. the interference of abusive domain name registrations with trademarks (cybersquatting). From the comparison of both examples the author derives some preliminary ideas regarding a theory of reflexive transnational law, suggesting that the established general trend of privatisation of civil law need to be accompanied by a civilisation of private law, i.e. the constitutionalization of transnational private regimes by embedding them into a procedural constitution of freedom
