The historical relatedness of an image was determined using the historical relatedness score of its top ten relevant tags.

From the results, it showed that the program achieved the project objective. It was able to search and retrieve the images according to their historical relatedness scores. In addition, it could perform the task efficiently, with an average retrieval time of 0.3s. However, it was found that certain limitations of the project affected the accuracy of some of the results. The first was due to the noisy nature of tags and the unrestricted feature of tagging. The second was due to Wikipedia Miner being based on the Wikipedia Hyperlink structure, which meant it depended on whether the term was in Wikipedia.
