T1  - Outcome Based Center Comparisons in Inpatient Cardiac Rehabilitation Results from the EVA-Reha (R) Cardiology Project
JF  - Die Rehabilitation : Zeitschrift für Praxis und Forschung in der Rehabilitation
N2  - Background: So far, for center comparisons in inpatient cardiac rehabilitation (CR), the objective outcome quality was neglected because of challenges in quantifying the overall success of CR. In this article, a multifactorial benchmark model measuring the individual rehabilitation success is presented.
 Methods: In 21 rehabilitation centers, 5 123 patients were consecutively enrolled between 01/2010 and 12/2012 in the prospective multicenter registry EVA-Reha (R) Cardiology. Changes in 13 indicators in the areas cardiovascular risk factors, physical performance and subjective health during rehabilitation were evaluated according to levels of severity. Changes were only rated for patients who needed a medical intervention. Additionally, the changes had to be clinically relevant. Therefore Minimal Important Differences (MID) were predefined. Ratings were combined to a single score, the multiple outcome criterion (MEK).
 Results: The MEK was determined for all patients (71.7 +/- 7.4 years, 76.9 % men) and consisted of an average of 5.6 indicators. After risk adjustment for sociodemographic and clinical baseline parameters, MEK was used for center ranking. In addition, individual results of indicators were compared with means of all study sites.
 Conclusion: With the method presented here, the outcome quality can be quantified and outcome-based comparisons of providers can be made.

T1  - Remixing entity linking evaluation datasets for focused benchmarking
JF  - Semantic Web
N2  - In recent years, named entity linking (NEL) tools were primarily developed in terms of a general approach, whereas today numerous tools are focusing on specific domains such as e.g. the mapping of persons and organizations only, or the annotation of locations or events in microposts. However, the available benchmark datasets necessary for the evaluation of NEL tools do not reflect this focalizing trend. We have analyzed the evaluation process applied in the NEL benchmarking framework GERBIL [in: Proceedings of the 24th International Conference on World Wide Web (WWW’15), International World Wide Web Conferences Steering Committee, Republic and Canton of Geneva, Switzerland, 2015, pp. 1133–1143, Semantic Web 9(5) (2018), 605–625] and all its benchmark datasets. Based on these insights we have extended the GERBIL framework to enable a more fine grained evaluation and in depth analysis of the available benchmark datasets with respect to different emphases. This paper presents the implementation of an adaptive filter for arbitrary entities and customized benchmark creation as well as the automated determination of typical NEL benchmark dataset properties, such as the extent of content-related ambiguity and diversity. These properties are integrated on different levels, which also enables to tailor customized new datasets out of the existing ones by remixing documents based on desired emphases. Besides a new system library to enrich provided NIF [in: International Semantic Web Conference (ISWC’13), Lecture Notes in Computer Science, Vol. 8219, Springer, Berlin, Heidelberg, 2013, pp. 98–113] datasets with statistical information, best practices for dataset remixing are presented, and an in depth analysis of the performance of entity linking systems on special focus datasets is presented.
