Abstract
This study explores the reconstruction of argumentative patterns through keywords in a newspaper corpus on multi-resistant organisms. Starting from manually identified frequent argumentation patterns based on a previous study by (Author, 2017), keywords are assigned to the argument they are assumed to point to. Keywords are calculated through three different measures (log likelihood, log ratio, adjusted log ratio) which cover different frequency ranges. This approach allows us to explore argumentation on varying levels of semantic granularity, showing that keywords of different frequency (and therefore different specificity) contribute to exploring discourse strategies. While an unambiguous category assignment is hardly achievable because frequent keywords appear in a wide range of contexts, keywords assigned to argumentation patterns do mostly occur in arguments. Most of our pre-determined argumentation patterns could be reconstructed using keyword methodology. Moreover, we identify two patterns absent from our original annotation scheme. Moreover, the different measures uncover words of noticeably different frequencies and thus argumentative specificity. Therefore, we deem keywords useful for exploring argumentative discourse.
Highlights
Multidrug-resistant organisms (MDRO) have been extensively covered in the media over recent decades
In consultation with researchers from Erlangen University Hospital, the following pathogens were used as seeds: Methicillin-resistant Staphylococcus aureus (MRSA), New Delhi metallo-beta-lactamase 1 (NDM1), Extended-spectrum beta-lactamase (ESBL), vancomycin-resistant enterococci (VRE), Carbapenem-resistant Enterobacteriaceae (CRE), K. pneumoniae carbapenemase (KPC), Acinetobacter baumannii and Pseudomonas aeruginosa
Argumentation patterns were divided into three broad categories
Summary
Multidrug-resistant organisms (MDRO) have been extensively covered in the media over recent decades. Pathogens like Methicillin-resistant Staphylococcus aureus (MRSA) pose threats especially in hospitals (nosocomial infections), where most infections are contracted (Cassini et al 2019). Medical studies have found that media coverage of MDRO influences family caregivers’ attitudes, and that laypeople strongly base their beliefs on news reports (Heckel et al 2017; Peters et al 2019). Gill et al (2006) report that press texts are the primary information source on medical topics for the public. According to Germany’s central medical institution Robert Koch Institute, approximately 10,000-15,000 annual casualties result from hospital-related infections; often from MDRO.. News coverage on this subject is likely relevant to the overall public perception of hospitals According to Germany’s central medical institution Robert Koch Institute, approximately 10,000-15,000 annual casualties result from hospital-related infections; often from MDRO. news coverage on this subject is likely relevant to the overall public perception of hospitals
