Enhancement of a first mind map to become a second enhanced mind includes: providing a content pool with information items; performing a first semantic scan based on a selected object; and generating a new object and a related connection to the selected object based on the semantic scan. Furthermore, the enhancement includes determining a strength value for each of the connections of the first mind map and determining the connection with the lowest strength value and recalculating the strength value using an external knowledge base to define the connection as obsolete if the strength value decreases.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A method for enhancing a first mind map, wherein the first mind map comprises objects and connections between the objects, comprising: providing a data source comprising a local content pool comprising information items; performing a first semantic scan based on a selected object out of the objects using a content as input; generating a new object, wherein the first semantic scan provides as output a semantic link between the selected object and the new object; generating a new connection between the selected object and the new object; determining a strength value for each of the connections of the first mind map based on a number of semantic links determined between each pair of connected objects of the first mind map by performing a second semantic scan against each information item of the local content pool using each pair of connected objects as input, wherein the strength value increases with the number of semantic links; determining a given connection with the lowest strength value in the first mind map; using a given object pair having the given connection with the lowest strength value within the first mind map as input for a third semantic scan and using information items of an external knowledge base for a recalculation of a new strength value for the given object pair; determining whether the given connection with the lowest strength value within the first mind map is obsolete by comparing the recalculated new strength value with a baseline strength value; and enhancing the first mind map by building a second mind map comprising only connections which are not obsolete and the objects corresponding to the non-obsolete connections. 2. The method according to claim 1, wherein the strength value is determined by: strength value=(OK—Ref−KO—Ref)/Ref, wherein OK_Ref=number of positive semantic links, KO_Ref=number of negative semantic links, Ref=total number information items used during the semantic scan. 3. The method according to claim 1, wherein the second mind map replaces the first mind map, and wherein the method is repeated in a next cycle thereby enhancing the mind map again. 4. The method according to claim 1, wherein the content is based on one out of a group comprising one or more of the following: a browser history; documents in a document folder; documents in a cloud repository; an e-mail database; a chat history; and a content management system. 5. The method according to claim 1, wherein the step of determining whether the given connection with the lowest strength value is obsolete comprises: determining whether the new strength value of the given connection is below a predefined strength threshold value. 6. The method according to claim 1, further comprising: generating a signal triggering a rendering of a visual representation of the objects and the connections between the objects of the first and/or the second mind map. 7. The method according to claim 6, wherein the strength value triggers a strength signal to influence a graphical unit to render a displayed connection according to the strength value. 8. The method according to claim 1, further comprising: providing a user interface adapted to redefine the strength value of a connection between two objects of the visual representation of the first and/or second mind map. 9. The method according to claim 1, further comprising: specifying the new connection. 10. The method according to claim 9, wherein the determining the strength value for each of the connections of the first mind map further comprises: using a specification of each of the connections as input for the determination of the strength value for each of the connections. 11.
