The Narrative Explorer is an interactive web application for text visualization and analysis. The texts are visualized in the Narrative Explorer in two ways. The affective content of the text, quantified as the sentiment polarity of the sentences, is represented by a bar graph timeline. The co-occurrence of characters or concepts in the text is represented by a chord diagram. These visual representations are linked and can be examined interactively. The Narrative Explorer allows the user to upload and visualize a new text or select an existing text from the database for visualization. The Narrative Explorer is intended for a variety of audiences, from humanities scholars and students engaged in exploratory text analysis to non-specialist readers interested in an analytical perspective on a familiar text.
