In this paper we study that how we can determine...
Digital Ecosystem is defined as ldquoan open, loosely coupled, domain clustered, demand-driven, self-organizing and agent-based environment, in which each species is proactive and responsive for its own benefit and profitrdquo [1]. Species in the Digital Ecosystem can play dual roles, which are service requester (client) service provider (server). A service provider enters the Digital Ecosystem by...

Crawlers are software which can traverse the Internet and retrieve Webpages by hyperlinks. In the face of the inundant spam Websites, traditional Web crawlers cannot function well to solve this problem. Semantic focused crawlers utilize semantic web technologies to analyze the semantics of hyperlinks and Web documents. This paper briefly reviews the recent studies on one category of semantic focused...
By analyzing the level of perceived risk in the domain of e-business, the interaction initiating agent can determine before hand whether or not it will achieve its desired outcomes and the associated consequences to it in interacting with the other agent. In our previous work, we have proposed a methodology by which the initiating agent ascertains the numeric level of perceived risk in forming an...
In the domain of e-commerce business it is important for the initiating agent of the interaction to analyze and consider the level of perceived risk in forming an interaction with an agent, apart from just considering the level of trust and security.

Risk is omnipresent in all the interactions that we carry out. Quantifying and making risk-based assessments and decisions is very important especially in the case of business interactions. However in the existing literature there is no ontological manifestation of risk and its related concepts. In this paper, we propose an ontological manifestation of risk. Subsequently it is extended to derive an...
This keynote will give an overview of the last 30 years of human system interaction and the key elements of human computer interaction (HCI) and its transition from traditional HCI into the frontier of human system interaction (HSI). This leads to the discussion as to why HSI is about digital ecosystems and about the world we live in rather than just ICT. We explain the 5 mega trends, and the emergence...
In an e-commerce business interaction, the risk assessing agent by analyzing the possible level of perceived risk beforehand can make an informed decision of its future course of interaction with an agent. The perceived risk in the context of an e-commerce business interaction is a multidimensional construct which is the combination of its subcategories. In this paper we propose a methodology by which...
The research with regards to digital ecosystems emerged in the end of last century, and has developed in this century. Due to its immaturity, some fields within it are deemed to be blank. This research proposes to fill one of the blanks in the digital ecosystems research. By analyzing the issues in the current research, we propose to develop a semantic search engine, with the purpose of querying services...
Todaypsilas e-businesses rely heavily on trust and reputation systems. These systems are key indicators for businesses performance. Businesses that interact with each other for their business needs form a digital business ecosystem (DBE). Members of DBE need to know the trust and reputation value of each other before the start of business interactions. The feedback mechanism is needed so that members...
With the surge of Service-Oriented Architecture (SOA) and Web services, service discovery has become increasingly crucial. Public Web services that are available "on the Web" provide unlimited values for a great number of online service consumers and developers. However, the public UDDI Business Registry - the primary service discovery mechanism over the Internet - has been shut down permanently...
In the literature, there is a lot of confusion regarding the relationship between the 'trust' and 'security'. Most of the times, these terms are regarded as being synonymous with each other. The existing literature does not draw a clear line how and when the terms of 'trust' and 'security' are synonymous and when they are not synonymous. In this paper we address this issue and discuss when the distinct...
