  abstract = {The challenge to provide tag recommendations for collaborative tagging systems has attracted quite some attention of researchers lately. However, most research focused on the evaluation and development of appropriate methods rather than tackling the practical challenges of how to integrate recommendation methods into real tagging systems, record and evaluate their performance. In this paper we describe the tag recommendation framework we developed for our social bookmark and publication sharing system BibSonomy. With the intention to develop, test, and evaluate recommendation algorithms and supporting cooperation with researchers, we designed the framework to be easily extensible, open for a variety of methods, and usable independent from BibSonomy. Furthermore, this paper presents a �rst evaluation of two exemplarily deployed recommendation methods.},

@inproceedings{koutrika2009flexrecs,
  abstract = {Recommendation systems have become very popular but most recommendation methods are ‘hard-wired’ into the system making experimentation with and implementation of new recommendation paradigms cumbersome. In this paper, we propose  FlexRecs, a framework that decouples the definition of a recommendation process
from its execution and supports flexible recommendations over structured data. In FlexRecs, a recommendation approach can be
defined declaratively as a high-level parameterized workflow comprising
traditional relational operators and new operators that generate or combine recommendations. We describe a prototype flexible recommendation engine that realizes the proposed framework and we present example workflows and  experimental results that show its potential for capturing multiple, existing or novel, recommendations
easily and having a flexible recommendation system that combines extensibility with reasonable performance.},
