Combining Information from Multiple Internet Sources

same place as the Consensus and 2 at the same place as the Game theory method.
To compare quality of those results the 3 top most URLs from each of the result sets were
investigated. Auction method provided us with Wikipedia definitions of the word Consensus and
Consensus decision making process. As the third URL Auction method provided an URL to
resource which is an interesting dispute about the real-life application of consensus decision
making. It presented some good and some ridiculous aspects of this decision process when dealing
with particular real-life situation Game theory method as the first URL provided the Wikipedia
definition of the word consensus. Second and third URL pointed to resources which were also
disputes about real life application of consensus decision making. In those resources one could find
essential information about how the consensus decision making process should be performed. The
three URLs returned by the Consensus method were the most promising however. Only one of
those contained raw definition but still more precise than the resource with definition from the
result set of Game theory. Two latter URLs did not contain the raw definitions of this process but
rather examples and requirements for this process to be applied successfully. Two of those were in
the three topmost URLs of the Game theory method as well. However Consensus answer was
inconsistent, so those results according to the Consensus theory are not a successful consensusmade
decision since many of the search engines’ result sets, which this answer was comprised of,
were highly dispersed. Nevertheless if to compare the result sets regardless if the consensus answer
was consistent or not, they results should be classified as follows:
1. Consensus method – provided most promising resources, not just raw definition of
consensus but rather definition of the process consensus decision making.
2. Game theory method – provided two interesting resources in the three top most URLs
and one raw definition of consensus (not consensus decision making)
3. Auction method – only one resource was something more than just raw definition of the
terms contained in the query.
The following part will present comparison of result sets returned by methods, with the
result set returned by MySpiders system.
MySpiders Auction Game theory Consensus
Set Coverage 60% 60% 70%

Table 4.1.9 Coverage of methods’ results and results of MySpiders system for simple query
The table 4.1.9 presents coverage of MySpiders system vs. the result sets returned by the
algorithms. It can be observed that MySpiders system as the 10 top URLs returns 6 URLs which are
in the Auction and Game theory method result sets. Consensus method is covered by 7 URLs. URL
to URL coverage is very low and only result set yield by Auction and Consensus method have at
least one URL (1 and 2 respectively) on the same position as the MySpiders system. Nevertheless,
set-coverage greater or equal 50% means that answer sets are very similar.
