Computing Literary Surplus Value: Alan Moore and the Density of the Comic Book as Graphic Novel

A. Dunst, R. Hartel, Anglia (2021), 139(1), pp. 195-223

<jats:title>Abstract</jats:title> <jats:p>The term graphic novel has increasingly functioned as a catalyst for understanding comic books as an emergent literary genre. This article focuses on one specific element within this historical process: the claim, made by artists such as Alan Moore, that graphic novels are characterized by greater formal complexity, or density, than serial comics. These claims are evaluated by combining computational text and image recognition of a corpus of 131 graphic narratives with sociological metadata on production and circulation. The results show that Moore’s own book-length comics, in particular <jats:italic>Watchmen</jats:italic> and <jats:italic>V for Vendetta</jats:italic>, rank among the densest graphic narratives in the sample in both their visual and textual content. Graphic memoirs, in contrast, only show an increase in textual complexity. With Pierre Bourdieu, the article understands complexity as a social and aesthetic strategy that aims at increasing the cultural capital of comics creators. At the same time, the article contextualizes computational results against the background of a changing marketplace for comics, in particular the decline of serial comics, the shift towards digital printing, and increased access to book distribution. This analysis shows that graphic narratives pursue both literary and popular aesthetic strategies, challenging Bourdieu’s account of a clear opposition between profit and prestige in cultural production.</jats:p>

Schema-based Parallel Compression and Decompression of XML Data

S. Böttcher, M. Feldotto, R. Hartel, in: WEBIST 2013 - Proceedings of the 9th International Conference on Web Information Systems and Technologies, Aachen, Germany, 8-10 May, 2013, 2013, pp. 77-86

Whenever huge amounts of XML data have to be transferred from a web server to multiple clients, the transferred data volumes can be reduced significantly by sending compressed XML instead of plain XML. Whenever applications require querying a compressed XML format and XML compression or decompression time is a bottleneck, parallel XML compression and parallel decompression may be of significant advantage. We choose the XML compressor XSDS as starting point for our new approach to parallel compression and parallel decompression of XML documents for the following reasons. First, XSDS generally reaches stronger compression ratios than other compressors like gzip, bzip2, and XMill. Second, in contrast to these compressors, XSDS not only supports XPath queries on compressed XML data, but also XPath queries can be evaluated on XSDS compressed data even faster than on uncompressed XML. We propose a String-search-based parsing approach to parallelize XML compression with XSDS, and we show that we can speed-up the compression of XML documents by a factor of 1.4 and that we can speed-up the decompression time even by a factor of up to 7 on a quad-core processor.
