Search engine mashup

06.07.2007
A mashup of two different types of web search tools could make find the useful nuggets of information among all the grit on the Internet much easier.

We have all experienced the inconvenience of trying to search for something on the World Wide Web and the search engine spewing back thousands of results, none of which look very relevant. The addition of almost 2.6 million new domain names since the launch of Europe's ".eu" domain in April 2006, means that the number of web pages available has grown substantially and any thoughts of taming all that new information seem futile.

To help solve the problem, information scientists Liu Wei and Chen Junjie of the Taiyuan University of Technology, in Shanxi, China, have brought together to distinct types of computer software to help them build a new search engine that can intelligently crawl other search engines. They describe their new search robot in Inderscience's International Journal of Agent-Oriented Software Engineering.

"Traditional search engines cannot cope easily with this rapid expansion of information resources, explains Junjie, something that is apparent across Europe and elsewhere as millions of new domains and sites come online.

He and his colleagues turned to the concept of search agent. Search agents, are intelligent virtual robots that can scan data very quickly looking for keywords and assessing the context of their findings. For instance, returning results related only to apples rather than Apple computers, when a fruit farmer searches for information on tasty new strains. There are several tools available to computer programmers for creating such agents. The researchers have then combined the search agent idea with another technology, the so-called meta search engine.

Meta searches involve scanning information, not from a single source, the Google or Yahoo index say, but from all available sources. Sites such as Bytesearch, MetaCrawler and Ixquick are well-known meta search tools.

The team has developed a new intelligent search agent and combined it with a meta search tool. The intelligent agent can determine the context of the user's search terms and choose appropriate search engines to scan. It then retrieves the most relevant results. Junjie explains that this approach, boosts the precision rate and the recall rate of traditional search engines, and fulfil users' query requests well.

Team member Liu Wei provides an example of how the system might work in practice. Suppose you are interested in a specific football team," he suggests, "our meta-search engine would find your user profile containing your interest in football, when you enter a keyword such as "football", the information on your favourite team from the various search engines will be retrieved preferentially." This not only boosts the precision rate and the recall rate of the meta-search engine but also assists with finding other more obscure information based on context.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
