Architecture of Docear’s research paper recommender system. Each article has a unique document id, a title, a cleantitle, on average there are around seven to eight revisions per mind-map. Rich, “User modeling via stereotypes,” Cognitive science , vol. This includes a list of all the mind-maps and revisions, their file sizes, the date they were created, and to which user they belong. Forwarding has the disadvantage that model. The dataset allows building available. The dataset also contains information where citations occur in the full-texts.

Comparing documents only based on such a simplified title is certainly not very sophisticated but it proved to be sufficiently effective for our needs. The system stores for which user the recommendations were generated, by which algorithm, as well as some statistical information such as the time required to generate recommendations and the original Lucene ranking. If two documents have the same cleantitle, the documents are assumed identical. To generate a cleantitle, all characters are transformed to lowercase, and only ASCII letters from a to z are kept. Related Work Several academic services published datasets, and hence have eased the process of researching and developing research paper recommender systems. The datasets are a unique source of findings. Click here to sign up.

For privacy reasons, Jack et al. Since the position of the citations is provided, recommender system From to he was assistant professor “Juniorprofessor” for information retrieval at the OVGU.

For each user, the label is randomly chosen, when the user registers. We randomly assign labels only to research the effect recommebder maps to analyze, the number of features the user model should different labels on user satisfaction. The CTR expresses the ratio of received and clicked recommendations.

Architectures of research paper recommender systems have only been published by a few authors. During the registration process, these users may provide information about their age and gender.


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

Converting in-text citations to Docear-IDs searching with Lucene for documents that cite a certain paper. Skip to main content.

For the future, we plan to release updated datasets annually or bi-annually, and we invite interested researchers to contact us for cooperation. The Ubiquitous Information Management and Communication mind-map dataset is smaller than the dataset e. In this case, Docear automatically creates a user account with a randomly selected user name that is tied to a users’ computer.

If the details on the offline evaluator, and potential shortcomings of offline resulting cleantitle is less than half the size of the original title, the evaluations, refer to [5].

Local users chose not to register when they introducong Docear. Due to spacial restrictions, the following sections provide only an overview of the most important data, particularly with regard to the randomly chosen variables. Anonymous users cannot login on Docear’s website, but they can receive recommendations as their mind-maps are transferred to Docear’s servers, if they wish to receive recommendations.

The developers of BibTiP [28] also published an architecture that is similar to the architecture of bX both bX researcj BibTip utilize usage data to generate recommendations. By publishing the recommender system’s architecture and datasets, we pursue three goals. The feature type may be terms, citations, or both. For privacy reasons, Jack, et al. Every time the recommendation process is triggered, one of these approaches is randomly chosen.

This is of particular importance, since the General Terms majority of researchers in the field of recommendsr paper recommender Algorithms, Design, Experimentation systems have no access to real-world recommender systems [11]. However, since we need the statistics, yet increases the variety of recommendations, and allows for the and want to evaluate different variations of the recommendation analyzing of how relevant the search results of Lucene are at approaches, pre-generating recommendation seems the most feasible different ranks.


This architecture has some relevance for recommender systems since many task in academic search are related to recommender systems e. This leads to The recommender system then only stored in the database.

His current research focuses on user centered approaches for information access and organization. Then, a number of other variables are chosen such as the number of mind-maps to analyze, the number of features the user model should contain, and the weighting scheme for the features.

The dataset they are using it, and how many papers they manage in their mind- also allows analyses about the use of reference managers, for maps, personal collections respectively. The offline evaluator checks if the removed citation is contained in the list of recommendations and stores this information in the database. These papers are about academic writing and search, i. By Joeran Beel and Bela Gipp. Third parties could use the Web Service, for instance, to request recommendations for a particular Docear user and to use the recommendations in their own application if the third party knew the user’s username and password.
