Abstract: The application relates to a method for facilitating the selection of an information source, comprising: providing two search strings to an electronic device; obtaining strings and relationship values, wherein each relationship value defines a degree of semantic relationship between two strings or a string and a search string and wherein at least some of the strings match with elements in the information sources; and displaying at least some of the matching strings on a two-dimensional map. The map comprises a first, a second and a third region, the first region comprising matching strings that have a non-zero relationship value only with regard to the first search string, the second region comprising matching strings that have a non-zero relationship value only with regard to the second search string and the third region comprising matching strings that have non-zero relationship values with regard to the first and the second search string.
