Auction Consensus Game theory<br />

Auction - 30% 30%<br />

Consensus 10% - 40%<br />

Game theory 0% 0% -<br />

Table 4.3.8 Coverage of methods for very complex query<br />

Table above illustrates coverage of result sets returned by the three methods. It can be<br />

observed that highest set-coverage (40%) is between result sets returned by Consensus and Game<br />

theory methods. In other cases the set-coverage is equal to 30%. URL to URL coverage is very low<br />

and it is non-zero (10%) only in case of Auction and Consensus method.<br />

As in the previous cases here, to compare the results content <strong>from</strong> 3 top most URLs <strong>from</strong><br />

each result set are investigated. Auction method as the 2 top most URLs returned suggestions<br />

provided by Google search engine, to search for the aforementioned query in its Google Scholar<br />

service. This however, does not point to any resource itself. As the third URL Auction method<br />

returned the Stanford Encyclopedia of philosophy webpage containing definition of Game theory.<br />

Game theory as the first URL returned the webpage containing information about institutional and<br />

behavioral economics. The second URL is the Google search engine suggestion, the same as the<br />

first URL returned by the Auction method. Third URL is a document about multi-agent systems and<br />

utilizing those as an approach to distributed artificial intelligence. Consensus as the two top most<br />

URL method returns those which were returned as 3 rd ones by the Game theory and Auction<br />

method. As the third URL it presented the article <strong>from</strong> Encyclopaedia Britannica about the Game<br />

theory in general.<br />

That said it seems that the search engines, when providing the URLs for this long and<br />

complex query, most of the time taken into account the term Game theory, rather than<br />

consensus, conflict or auction terms. Probably out of these topics, the Game theory is<br />

the most popular topic which could be found in <strong>Internet</strong>. This may not be the results which one<br />

could be expecting when issuing this query, but since this query is very complex, the search engines<br />

may have gotten confused. But this is a work of the algorithms presented here, to remove the<br />

confusion <strong>from</strong> the result sets, thus providing the best possible results. Nevertheless, here is the<br />

subjective comparison of the results:<br />

1. Consensus – no link which is a suggestion to use some other search engine, the URLs<br />

which were described, all point to the real resource<br />

2. Game theory – one link which is a suggestion to use other search, two URLs pointed to a<br />

real resources<br />

3. Auction – two links were suggestion to use another search, one pointed to a real resource<br />

There is no comparison of methods vs. MySpiders for this query. Query proven to complex<br />

for MySpiders to handle – it is a content based search and probably it did not find any resource<br />

which contained all of the terms <strong>from</strong> the issued query. In turn MySpiders did not return any URL<br />

for this query.<br />
