Lotte and Annette: A Framework for Finding and Exploring Key Passages in Literary Works
Frederik Arnold | Robert Jäschke
Proceedings of the Workshop on Natural Language Processing for Digital Humanities

We present an approach that leverages expert knowledge contained in scholarly works to automatically identify key passages in literary works. Specifically, we extend a text reuse detection method for finding quotations, such that our system Lotte can deal with common properties of quotations, for example, ellipses or inaccurate quotations. An evaluation shows that Lotte outperforms four existing approaches. To generate key passages, we combine overlapping quotations from multiple scholarly texts. An interactive website, called Annette, for visualizing and exploring key passages makes the results accessible and explorable.
