Abstract
The disclosed relates to a system for generating a refined query, whereby the system comprises or is coupled with a search engine for searching through a tree of query modification operations, whereby the root node of said tree is an empty node which represents a given initial query, and comprises at least one processor which is configured to perform the following steps:a) defining a set of query modification operators which can be inserted into said tree;b) receiving a second set of reference query results;c) receiving a first set of current query results from a currently given query comprising one or more triple patterns;d) contrasting the first set of query results with the second set of query results by assessing the differences between the two query results;e) running the search engine which is configured to perform the following steps:f) selecting a node of said tree by a computed score derived from the assessed result;g) selecting any query modification operator of the defined set of query modification operators;h) if the selected query modification operator does not correspond to any of the triple patterns of the query represented by the selected node, then continue step f)…
