Abstract:
|
Edgar Allan Poe wrote almost seventy short stories in his lifetime, and literary critics have categorized these stories in many ways, (e.g., by genres such as horror, detective, or proto-science fiction). This talk discusses how a computer can group stories by using families of words related by a theme, e.g., words denoting colors. This approach combines two different techniques. First, we use term-document matrices, which were originally developed for document searches in the field of information retrieval. Second, we use formal concept theory, which defines concepts in a way that forms a Galois lattice. These lattices have both a well developed mathematical basis and have been used in applications beyond the computer sciences, (e.g., social networks in mathematical sociology). Finally, we will discuss how meaningful these groups of stories are to a human reader.
