For instance, the optimal size of an algorithms' user model depended on users' age. Some of the determinants have interdependencies. Determinants we examined include user characteristics (gender and age), datasets, weighting schemes, the time at which recommendations were shown, and user-model size. We found several determinants that may contribute to the large discrepancies observed in recommendation effectiveness. For example, in one news-recommendation scenario, the performance of a content-based filtering approach was twice as high as the second-best approach, while in another scenario the same content-based filtering approach was the worst performing approach. The experiments show that there are large discrepancies in the effectiveness of identical recommendation approaches in only slightly different scenarios, as well as large discrepancies for slightly different approaches in identical scenarios. We conduct experiments using Plista's news recommender system, and Docear's research-paper recommender system.

In this article, we examine the challenge of reproducibility in recommender-system research. However, comparing their effectiveness is a challenging task because evaluation results are rarely reproducible. Numerous recommendation approaches are in use today. The datasets are a unique source of information to enable, for instance, research on collaborative filtering, content-based filtering, and the use of reference-management and mind-mapping software. The four datasets contain metadata of 9.4 million academic articles, including 1.8 million articles publicly available on the Web the articles' citation network anonymized information on 8,059 Docear users information about the users' 52,202 mind-maps and personal libraries and details on the 308,146 recommendations that the recommender system delivered. It supports researchers and developers in building their own research paper recommender systems, and is, to the best of our knowledge, the most comprehensive architecture that has been released in this field. for crawling PDFs, generating user models, and calculating content-based recommendations. The architecture comprises of multiple components, e.g. In this paper, we introduce the architecture of the recommender system and four datasets.

In the past few years, we have developed a research paper recommender system for our reference management software Docear.
