Making Sure That The Internet Is Efficient

There are some 800 million pages filled with information when it comes to the World

Wide Web but when people use Internet search engines they are only able to reach about half of these pages based on a new study by a team of computer scientists. With regard to indexing the Web, search engines are making less of an effort to do so. When it comes to one institute, a computer and communications firm owns it.

There was one similar study done at the end of 1997 and they were able to find out that from the top six search engines came about a 60 percent coverage of the Web and from this the top search engine was able to hit one third of all sites. Reported by one well known journal last February were results pertaining to finding only 42 percent of all sites in a test of 11 top search engines not to mention not finding a program that is able to cover more than about 16 percent of the Web.

Concerning the Web, it promised to finally make an effort to equalize access to information but what search engines are doing nowadays is focusing more on indexing the sites that have more links to them and as these popular sites gain more publicity those which have good information are often disregarded.

Just 14 months after they came out with their first estimate of having 320 million pages of Internet information and content that they found the number of pages to be twice this initial estimate and so there is definitely more ground that needs patrolling. There is 6 trillion bytes of information on the Web but the library of congress has 20 trillion bytes. Researchers engaged in a random surfing exercise of 2,500 Web sites and they found out that there was close to 3 million servers available publicly each one with 289 pages.

Considering that just a few sites may have millions of pages, they said that it is possible to have even more information available on the Net. Their test of servers found about 83 percent of them contained commercial content company Web pages, catalogues and the like, with just 6 percent involving scientific or educational material, just under 3 percent with health information, just over 2 percent personal Web pages, and 2 percent with pornographic content. When it comes to what makes so much of the Web hard to find, the culprit is not the volume but the techniques used by search engines.

The two main methods used by search providers when looking for pages include user registration as well as following links to new pages. According to researchers, what search engines do is make a biased sample of the Web because what they do is follow links to new pages where they end up finding and indexing pages that have more links to them. This is not a matter of having a lack of the ability to do the indexing, it is more of making the resources have alternative benefits to the users like free email which could be of great value to some.

There is a search engine expert and according to him a lot of people usually do not notice what they are not seeing because most of the information requests are simple. With regard to the imbalance in cataloguing this is expected to continue for some time and this is because the production of information content by humans to be posted on new sites will move slower than the rate of increase in computer resources.
