Description

Semantic-based technology made cheaper and more accessible


The Web is easy to access but allows only limited forms of knowledge sharing for simple tasks. The content is mostly only readable by humans and also the way people can access this information is narrowly limited.

The OpenKnowledge project is focusing on semantics related to interaction and provides a novel form of peer to peer knowledge sharing in open environments. Open in the sense that anyone can join at any time and exhibit openness to being joined, at low individual cost. The project is using interaction model routing; context maintenance; dynamic ontology matching and visualisation to avoid scaling problems found in traditional systems.
The methods are being applied to problems in bioinformatics and emergency response, with further applications in biomedicine coming up. Eventually the OpenKnowledge architecture is intended to be for everyone.


A new form of open, coordinated knowledge sharing architecture

OpenKnowledge (OK) is a Peer-to-Peer network of knowledge providers. Each computer that acts as an OK peer, will be able to provide services to other peers and use services from others in the form of OK Components (OKCs). These Components will use the core services provided in the architecture to interact with each other and accomplish the tasks the end user desires.

Interaction between OKCs is a very important part of the architecture. Through a simple language, developers will be able to define the Interaction Models (IM) that specify the protocols that must be followed in order to offer or consume a service.

The OpenKnowledge kernel is a compact program that automatically finds interaction models that you might want to use; allows you to subscribe to interctions that interest you; and interprets the interaction models in which you actually become involved.

The kernel provides a rich context for interactions between peers, thanks to the LCC (Lightweight Coordination Calculus) model that is used to facilitate coordination.

In place are an integrative architecture and an implemented kernel system, supplemented by verification methods and demonstrator applications. As far as is know, this is the first single system that shares interction models in a peer to peer style and uses these to coordinate peers in an opportunistic but reliable way.

OpenKnowledge are developing applications in numerous domains, focusing on two contrasting areas: bioinformatics and emergency collaboration. The methods in practice:

Bioinformatics (shows how to use interaction modelling to discover a new proteomics results).
e-Science (shows how scientists in astrophysics can view their e-science experiment designs as interaction models).
Emergency response (shows how simulations can be used to test real-time interaction models).
Further research will be done with the peer-to-peer interaction model routing, the dynamic ontology mapping, the 'Good enough answers' and trust metrics. Also the project will explore how the OpenKnowledge approach can be integrated with established, user-centred applications for the semantic web, such as Magpie (supports web browsing by exploiting semantic data associated with the viewed web pages) and Aqualog (an ontology based question answering system).

Each research focus feeds back to the system kernel, which will become generally available, both as a downloadable system and as open source software.

To expand beyond the test beds, the project is in the process of developing links to other groups who want to use the OpenKnowledge technology in their own research. The first promising new direction is in medicine, where possibly the OpenKnowledge technology will support medical knowledge sharing and protocol deployment in the UK and in China.

Cel

The existing, open Worldwide Web has been successful on a global scale because the cost of participation at a basic level is low and the individual benefit of participation is immediate, risingrapidly as more participants take part. The same cannot currently be said about semantic based systems because the cost of being precise about semantics for sophisticated components is prohibitively high andthe cost of ensuring an individual, absolute semantics for a component rises rapidly as more participants take part. OpenKnowledge aims to break out of this deadlock by focusing on semantics related tointeraction (which are acquired at low cost during participation) and using this to avoid dependency on a priori semantic agreement; instead making semantic commitments incrementally at run time. The"Open" in OpenKnowledge thus is significant in two senses: it assumes an open system, which anyone may join at any time; it assumes an openness to being joined, achieved through participation at low individual cost.
We shall provide a unifying framework based on interaction models that are mobile in the sense that they may be transferred to other components, this being a mechanism for Web service composition and for coalition formation. A key contribution of OpenKnowledge is to demonstrate that by shifting the emphasis to interaction (the details of which may be hidden from users) we can obtain knowledge sharing of sufficient quality for sustainable communities of practice without the barrier of complex meta-data provision prior to community formation. We ground our research in two testbed arenas: bioinformatics and emergency response.
