Parallel Web Spiders for Cooperative Information Gathering
Web spider is a widely used approach to obtain information for search engines. As the size of the Web grows, it becomes a natural choice to parallelize the spider’s crawling process. This paper presents a parallel web spider model based on multi-agent system for cooperative information gathering. It uses the dynamic assignment mechanism to wipe off redundant web pages caused by parallelization....
متن کامل10. Personalized and Focused Web Spiders
As the size of the Web continues to grow, searching it for useful information has become increasingly difficult. Researchers have studied different ways to search the Web automatically using programs that have been known as spiders, crawlers, Web robots, Web agents, Webbots, etc. In this chapter, we will review research in this area, present two case studies, and suggest some future research di...
متن کاملSpatial learning affects thread tension control in orb-web spiders.
Although it is well known that spatial learning can be important in the biology of predators that actively move around in search for food, comparatively little is known about ways in which spatial learning might function in the strategies of sit-and-wait predators. In this study, Cyclosa octotuberculata, an orb-web spider that uses its legs to contract radial threads of its web to increase thre...
متن کاملWeb orientation and prey resources for web-building spiders in eastern hemlock.
We examined the arthropod community on eastern hemlock, Tsuga canadensis (L.) Carr, in the context of its role in providing potential prey items for hemlock-associated web-weaving spiders. Using sticky traps simulating spider webs, we evaluated what prey items are available to web-weaving spiders in eastern hemlock based on web orientation (horizontal versus vertical) and cardinal direction. W...
متن کاملPrey interception drives web invasion and spider size determines successful web takeover in nocturnal orb-web spiders
A striking feature of web-building spiders is the use of silk to make webs, mainly for prey capture. However, building a web is energetically expensive and increases the risk of predation. To reduce such costs and still have access to abundant prey, some web-building spiders have evolved web invasion behaviour. In general, no consistent patterns of web invasion have emerged and the factors dete...
