On the Emergent SemanticWeb and Overlooked Issues 

On the Emergent SemanticWeb and Overlooked Issues
"Abstract. The emergent SemanticWeb, despite being in its infancy, has already received a lot of attention from academia and industry. This resulted in an abundance of prototype systems and discussion most of which are centred around the underlying infrastructure. However, when we critically review the work done to date we realise that there is little discussion with respect to the vision of the SemanticWeb. In particular, there is an observed dearth of discussion on how to deliver knowledge sharing in an environment such as the SemanticWeb in effective and efficient manners. There are a lot of overlooked issues, associated with agents and trust to hidden assumptions made with respect to knowledge representation and robust reasoning in a distributed environment. These issues could potentially hinder further development if not considered at the early stages of designing Semantic Web systems. In this perspectives’ paper, we aim to help engineers and practitioners of the SemanticWeb by raising awareness of these issues."

Ontology-Driven Software Development in the Context of the Semantic Web: An Example Scenario with Protege/OWL 

Ontology-Driven Software Development in the Context of the Semantic Web: An Example Scenario with Protege/OWL
"Abstract
Recent efforts towards the Semantic Web vision have lead to a number of standards such as OWL and Web Service languages. While these standards provide a technical infrastructure, software developers have little guidance on how to build real-world Semantic Web applications. Based on a realistic application scenario, we present some initial thoughts on a software architecture and a development methodology forWeb services and agents for the SemanticWeb. This architecture is driven by formal domain models (ontologies). The methodology applies best practices from agile development methodologies, including systematic tests, short feedback loops, and close involvement of domain experts. We illustrate how these techniques can be put into practice using the modern Semantic Web development tool Protege, and indicate future possibilities."

"This page is an experiment in using the wiki for collaborative work on a W3C Working Group document, intended ultimately for publication as a note. Edits from non-WG members are welcome, but for now please keep them modest in scope (eg. don't break this longish document out into separate pages for us). We realise that this might be a break from wiki culture, but we are working with additional constraints, which is that we want to be able to get this text back out of the wiki again for W3C publication. --DanBri, Thomas Baker, W3C SW Best Practices WG."

Ehrig, Staab: QOM - Quick Ontology Mapping 

Ehrig, Staab: QOM - Quick Ontology Mapping: "Abstract
(Semi-)automatic mapping - also called (semi-)automatic alignment - of ontologies is a core task to achieve interoperability when two agents or services use different ontologies. In the existing literature, the focus has so far been on improving the quality of mapping results.We here consider QOM, Quick Ontology Mapping, as a way to trade off between effectiveness (i.e. quality) and efficiency of the mapping generation algorithms. We show that QOM has lower run-time complexity than existing prominent approaches. Then, we show in experiments that this theoretical investigation translates into practical benefits. While QOM gives up some of the possibilities for producing high-quality results in favor of efficiency, our experiments show that this loss of quality is marginal.

Bipartite Graphs as Intermediate Model for RDF 

Bipartite Graphs as Intermediate Model for RDF
"Abstract. RDF Graphs are sets of assertions in the form of subject predicate-object triples of information resources. Although for simple examples they can be understood intuitively as directed labeled graphs, this representation does not scale well for more complex cases, particularly regarding the central notion of connectivity of resources. We argue in this paper that there is need for an intermediate representation of RDF to enable the application of well-established methods from graph theory. We introduce the concept of RDF Bipartite Graph and show its advantages as intermediate model between the abstract triple syntax and data structures used by applications. In the light of this model we explore the issues of transformation costs, data/schemastructure, and the notion of RDF connectivity."

Crucial factors in the origins of word-meaning 

Crucial factors in the origins of word-meaning
"0.1. Introduction
We have been conducting large-scale public experiments with artificial robotic agents to explore what the necessary and sufficient prerequisites are for word-meaning pairs to evolve autonomously in a population of agents through a self-organized process. We focus not so much on the question of why language has evolved but rather on how. There are many good reasons to use language once it has come into existence; for example, for establishing and maintaining group coherence, for transmission of cultural knowledge like tool use, etc. But these reasons only explain why verbal behavior is reinforced, it does not explain how this verbal behavior might emerge or complexify. Our hypothesis is that when agents engage in particular interactive behaviors which in turn require specific cognitive structures, they automatically arrive at a language system. This interactive behavior should be a natural outgrowth of cooperative behavior (if this were not the case, the behavior would be unlikely to emerge), and the cognitive structures should be simple enough to have evolved for other purposes as well (pre-adaptation). Our main task is therefore to identify precisely what this behavior is and what cognitive structures are required for it."

Situated Grounded Word Semantics 

This seems to be a shorter version of the prior reference Situated Grounded Word Semantics
"Abstract
The paper reports on experiments in which autonomous
visually grounded agents bootstrap
an ontology and a shared lexicon without prior
design nor other forms of human intervention.
The agents do so while playing a particular language
game called the guessing game. We show
that synonymy and polysemy arise as emergent
properties in the language but also that there
are tendencies to dampen it so as to make the
language more coherent and thus more optimal
from the viewpoints of communicative success,
cognitive complexity, and learnability."

Bootstrapping Grounded Word Semantics 

Bootstrapping Grounded Word Semantics
"Abstract
The paper reports on experiments with a population of visually grounded robotic agents capable of bootstrapping their own ontology and shared lexicon without prior design nor other forms of human intervention. The agents do so while playing a particular language game called the guessing game. We show that synonymy and ambiguity arise as emergent properties in the lexicon, due to the situated grounded character of the agent-environment interaction, but that there are also tendencies to dampen them so as to make the language more coherent and thus more optimal from the viewpoints of communicative success, cognitive complexity, and learnability."

Emergent semantics (from Deleuze) and the semantic web, 15/09/04, Soft[ware] Subversions 

Emergent semantics (from Deleuze) and the semantic web, 15/09/04, Soft[ware] Subversions
"...This raises a question about the semantic web, which attempts to move us to a model for linking content that works with these emergent semantic processes. The idea seems to be this. A document is the static representation of a web of meaning (problem spaces and solutions interacting with each other). That web of meaning is seen to come from the author. A so called 'intelligent agent' is capable of drawing out and representing these meanings with some kind of schema that links them up with other documents and makes them accessible to others using the same schema.
...
Perhaps a better approach would be to allow the reader to create their own conceptual map of the significant elements of a document, and then search for other simlar maps that apply to other documents. That really would be a semantic web."
