Technical solutions are described for visually depicting health of a cognitive system. An example computer-implemented method includes accessing a query-log of a question input to the cognitive system. The method also includes generating a query-node corresponding to the question. The method also includes configuring animation parameters of the query-node based on the query-log. The method also includes displaying the query-node according to the animation parameters.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. A computer implemented method for visually depicting health of a cognitive system, the method comprising: accessing a query-log of a question input to the cognitive system; generating a query-node corresponding to the question; configuring animation parameters of the query-node based on the query-log; and displaying the query-node according to the animation parameters. 2. The computer implemented method of claim 1, wherein the query-log comprises a confidence value associated with the question. 3. The computer implemented method of claim 1, wherein the query-log comprises a category associated with the question. 4. The computer implemented method of claim 1, wherein configuring the animation parameters comprises determining position coordinates of the query-node. 5. The computer implemented method of claim 4, wherein the position coordinates are determined based on animation parameters of neighboring query-nodes. 6. The computer implemented method of claim 5, wherein the neighboring query-nodes are located within a predetermined distance from the query-node. 7. The computer implemented method of claim 1, wherein configuring the animation parameters comprises determining a color of the query-node. 8. The computer implemented method of claim 7, wherein the color of the query-node is based on a difference between a confidence value corresponding to the question and a confidence threshold. 9. The computer implemented method of claim 8, further comprising receiving the confidence threshold at runtime. 10. A system for visually depicting health of a cognitive system, the system comprising: a memory; a display unit; and a processor coupled with the memory and the display unit, the processor configured to: access a query-log of a question input to the cognitive system; generate a query-node corresponding to the question; configure animation parameters of the query-node based on the query-log; and cause the display unit to display the query-node according to the animation parameters. 11. The system of claim 10, wherein the query-log comprises a confidence value associated with the question. 12. The system of claim 10, wherein the query-log comprises a category associated with the question. 13. The system of claim 10, wherein configuring the animation parameters comprises determining position coordinates of the query-node. 14. The system of claim 13, wherein the position coordinates are determined based on animation parameters of neighboring query-nodes. 15. The system of claim 10, wherein configuring the animation parameters comprises determining a color of the query-node. 16. The system of claim 15, wherein the color of the query-node is based on a difference between a confidence value corresponding to the question and a confidence threshold. 17. A computer program product for visually depicting health of a cognitive system, the computer program product comprising a computer readable storage medium, the computer readable storage medium comprising computer executable instructions, wherein the computer readable storage medium comprises instructions to: access a query-log of a question input to the cognitive system; generate a query-node corresponding to the question; configure animation parameters of the query-node based on the query-log; and cause a display unit to display the query-node according to the animation parameters. 18. The computer program product of claim 17, wherein the query-log comprises a confidence value associated with the question. 19. The computer program product of claim 17, wherein the query-log comprises a category associated with the question. 20. The computer program product of claim 17, wherein configuring the animation parameters comprises determining position coordinates of the query-node.
