@inproceedings{kowald2014probability, abstract = {In this paper, we introduce a tag recommendation algorithm that mimics the way humans draw on items in their long-term memory. This approach uses the frequency and recency of previous tag assignments to estimate the probability of reusing a particular tag. Using three real-world folksonomies gathered from bookmarks in BibSonomy, CiteULike and Flickr, we show how incorporating a time-dependent component outperforms conventional "most popular tags" approaches and another existing and very effective but less theory-driven, time-dependent recommendation mechanism. By combining our approach with a simple resource-specific frequency analysis, our algorithm outperforms other well-established algorithms, such as FolkRank, Pairwise Interaction Tensor Factorization and Collaborative Filtering. We conclude that our approach provides an accurate and computationally efficient model of a user's temporal tagging behavior. We demonstrate how effective principles of information retrieval can be designed and implemented if human memory processes are taken into account.}, acmid = {2576934}, address = {Republic and Canton of Geneva, Switzerland}, author = {Kowald, Dominik and Seitlinger, Paul and Trattner, Christoph and Ley, Tobias}, booktitle = {Proceedings of the Companion Publication of the 23rd International Conference on World Wide Web Companion}, doi = {10.1145/2567948.2576934}, interhash = {911a425fa4f6e883c32fa7a09840bdd8}, intrahash = {659fca43cb6751ee9b13297b797d91e1}, isbn = {978-1-4503-2745-9}, location = {Seoul, Korea}, numpages = {6}, pages = {463--468}, publisher = {International World Wide Web Conferences Steering Committee}, series = {WWW Companion '14}, title = {Long Time No See: The Probability of Reusing Tags As a Function of Frequency and Recency}, url = {http://dx.doi.org/10.1145/2567948.2576934}, year = 2014 }
