Consider a group of documents that has been selected from a much larger set of diverse documents so that the selected documents are as dissimilar from one another as possible. If we consider documents that are not highly related (connected, similar) to one another as being anomalous, then all of the documents that we have selected might be classified as anomalous. Discuss whether it is possible for a data set to consist only of anomalous objects, or if it is an abuse of the terminology? Cite the sources you use to make your response.
