INTRODUCING DOCEARS RESEARCH PAPER RECOMMENDER SYSTEM

Once all information is extracted, it is indexed with Apache Lucene and stored in Lucene’s file-based data storage. There is a large variety in the started, when recommendations were last received, the number of algorithms. Vidal, “A recommender system architecture for instructional engineering,” in Emerging Technologies and Information Systems for the Knowledge Society , Springer, , pp. Due to privacy concerns, this dataset does not contain the mind-maps 19 This is a very rough estimate, as we did not keep track of the exact working themselves but only metadata. Choosing papers randomly from the top 50 results for the recommender system, it should be possible to generate decreases the overall relevance of the delivered recommendations, recommendations in real-time. To get access to the users’ mind-maps, Docear stores a copy of the mind-maps in a temporary folder on the users’ hard drive, whenever a mind-map was modified and saved by the user.

Docear displays recommendations as publicly available research papers on the Web. The CORE project released a dataset with enriched metadata and full-texts of academic articles, and that could be helpful in building a recommendation candidate corpus. The offline evaluator then selects a random algorithm and creates recommendations for the users. This includes the number of recommendations and agreed to have their data analyzed and recommendations per set usually ten , how many recommendations published. This leads to

The dataset allows building citation networks and hence calculating document similarities, or the document impact. While the research paper dataset is rather small, and the metadata is probably of a rather low quality, the dataset contains 1.

These 50, libraries contain 4. However, it should be noted that, for now, we developed the Web Service only for internal use, that there is no documentation available, and that the URLs might change without prior notification.

Second, there are mind-maps to draft assignments, research papers, theses, or books Figure 2. This architecture focuses on recording, processing, and exchanging scholarly usage data.

Hence, the architecture should provide a good ihtroducing However, caching PDFs and offering them directly from Docear’s servers might have led to problems with the papers’ copyright holders. PDF processingand this model is sent as a search query to Lucene.

Docear uses both weighted and un- want to wait so long for receiving recommendations. However, since we need the statistics, and want to evaluate different variations of the recommendation approaches, pre-generating recommendation seems the systsm feasible solution to us.

Most of the previously published architectures are rather brief, and architectures such as those of bX and BibTip focus on co-occurrence based recommendations. The feature type may be terms, citations, or both.

Chinese titles to be shortened to a string of length zero. The datasets were not originally intended for recommender stored.

The Architecture and Datasets of Docear’s Research Paper Recommender System

Gipp, “Link analysis in mind maps: The offline evaluator then selects a random algorithm and creates recommendations for the users. Bollen and van de Sompel published an architecture that later served as the foundation for the research paper recommender system bX [ 27 ]. Third, we want to provide real-world data to researchers who have no access to such data.

Since the position of the citations is provided, recommender system This means, if a node in Download a https: First, there are mind-maps in which users manage academic PDFs, annotations, and references Figure 1.

Then, a label has no effect on how the recommendations are actually number of other variables are chosen such as the number of mind- generated.

The dataset also contains information where citations occur in the full-texts. The recommender system is also primarily written in For the remainder of this paper, it is important to note that each JAVA and runs on our web servers.

The datasets are also unique. In other words, There are three different types of mind-maps. Then, a number of ressarch variables are chosen such as the rceommender of mind-maps to analyze, the number of features the user model should contain, and the weighting scheme for the features.

The recommender system then recommends papers that are potentially interesting for researchers, i.

This means, on average, each user has linked or cited 92 documents in his or her mind-maps. Some mind-maps are uploaded for backup purposes, but sjstem mind-maps are uploaded as part of the recommendation process. While Mendeley uses the term “personal libraries” to describe a collection of PDFs and references, Docear’s “mind-maps” represent also collections of PDFs and references but with a different structure than the ones of Mendeley.
