Spider:
A program that automatically fetches Web pages. Spiders are used to feed pages to search engines. It's called a spider because it crawls over the Web. Another term for these programs is webcrawler.
contain links to other pages, a spider can start almost anywhere. As soon as it sees a link to another page, it goes off and fetches it. Large search engines, like Alta Vista, have many spiders working in parallel.
A lot of Content and Links displayed on a webpage may not actually be visible to the Search Engines, eg. Flash based content, content generated through javascript, content displayed as images etc.
This tool Simulates a Search Engine by displaying the contents of a webpage exactly how a Search Engine would see it.
It also displays the hyperlinks that will be followed (crawled) by a Search Engine when it visits the particular webpage.
Software agents
Simplifying the complexities of distributed computing and overcoming the limitations of current user interface approaches. The final section provides a chapter by chapter overview of the emainder of the book.the two definitions of an agent that have been attempted:agent as an ascription, and agent as a description.
Agent ascription:
As previously noted, one of the most striking things about recent research and development in software agents is how little commonality there is between different approaches. Yet there is something that we intuitively recognize as a “family resemblance” among them. Since this esemblance cannot have to do with similarity in the details of implementation, architecture, or theory, it must be to a great degree a function of the eye of the beholder. “Agent is that agent
does”4 is a slogan that captures, albeit simplistically, the essence of the insight that agency cannot ultimately be characterized by listing a collection of attributes but rather consists fundamentally as an attribution on the part of some person
Agent description:
A more specific definition of “software agent” that many agent researchers might find acceptable is: a software entity which functions continuously and autonomously in a particular environment, often inhabited by other agents and processes. The requirement for continuity and autonomy derives from our desire that an agent be able to carry out activities in a flexible and intelligent manner that is responsive to changes in the environment without requiring constant human uidance or intervention. Ideally, an agent that functions continuously in an environment over a long period of time would be able to learn from its experience. In addition, we expect an agent that inhabits an environment with other agents and processes to be able to communicate and cooperate with them, and perhaps move from place to place in doing so.
Identify various activities in e-commerce where software agents are currently in use.
As internet and technology emerges, virtual environments become widely used as mediums for conducting many applications such as entertainment, gaming, and training. However, the use of hese environments as mediums for conducting virtual shopping is little and the relation of trust, an important factor to increase costumers’ purchases in the physical world, might be among the reasons for such little use. In the current study, we discuss the importance of the continuous resence of software agent in the absence of the underlying vendor to increase e-clients virtual transactions.
