Updated on 2017-08-14: Here at Docear and Mr. DLib we have many exciting projects in the field of recommender systems, user modelling, personalisation, and adaptive systems (primarily with a focus on digital libraries but we are also open for domains such as health care, transportation, and tourism). If you are interested in pursuing any of the projects as part of a Bachelor, Master, or PhD thesis, as a post-doctoral researcher, or as a short-term research internship, read on.
We have a number of interesting projects but please consider the following list only as a suggestion. If you have your own ideas, you are very welcome to discuss them with us. In general we are interested in anything relating to user modelling, personalization, and recommender systems in the domains of digital libraries, tourism, health care, and transportation. However, our recommender systems and reference management tools are real-world applications — hence, we are also interested in topics such as software design and architecture, scalability, parallelization, and databases.
Whatever project you choose, we can guarantee that you will be working on a real-world software system being used by tens of thousands of researchers around the globe. You will gain valuable insights into research and software development that will help you in both, pursuing a career in the industry and academia.
Mr. DLib is our new project that offers literature recommendations as a service. The service is currently used by our pilot partner GESIS and JabRef, and further partners are soon to come. Mr. DLib delivers more than 10,000 recommendations per day, which is ideal for conducting research about recommender systems. Actually, a lot of current research in the domain of (literature) recommender systems suffers from artificial lab scenarios and little relevance for real-world applications. When you conduct your research about recommender systems with Mr. DLib you can be sure that your results will have a high practical relevance and help to shape the way academics receive recommendations in the real word.
A Novel Recommendation Approach for Scientific Recommender Systems
There are more than 90 approaches to give research-paper recommendations. Your goal will be to develop a novel research-paper recommendation approach that is more effective than those ones currently being available. To achieve the goal, you will be integrating some of the existing approaches into Mr. DLib’s “Recommender System as a Service”, and either develop a completely new approach, or enhance the existing ones. We have many ideas how existing approaches could be enhanced. For instance, the ranking process could be improved by using Scientometrics (e.g. citation counts of papers, h-index, …) or machine learning, and there are many options more that we are happy to share with you in a personal discussion.
Reproducibility in Recommender-System Research
The reproducibility of experimental results is the “fundamental assumption” in science, and the “cornerstone” for drawing meaningful conclusions. Recently, we found that reproducibility is rarely given in the recommender-systems community, particularly in the research-paper recommender-system community. In a review of 90 research-paper recommender systems, we identified several cases in which only slight variations in the initial setup of the evaluation or approaches led to surprisingly different results.
We want to find out, how recommender systems should be ideally implemented and evaluated to ensure reproducible results. To achieve the goal,
- you will implement a number of research-paper recommendation approaches (or simply use some existing ones),
- then these approaches will be used to give recommendations to the users of the applications that use Mr. DLib’s recommender system (GESIS, JabRef, Docear, and maybe others)
- you will analyze how the recommendation approaches perform in the different scenarios and you try to identify the factors that affect the recommendation effectiveness. This includes making controlled changes to the algorithms and applications that display the recommendations.
If you are interested in this project, please have a look at our paper that was published in the journal “User Modeling and User Adapted Interaction (UMAI)”. The paper gives you a detailed overview on the topic of reproducibility. Your task would be to continue what we outlined in that paper.
Docear is a reference manager, comparable to tools like JabRef, Endnote, Zotero, or Mendeley. In the past year(s) the development of Docear paused somewhat, but we would love to have someone who brigs new life to the project. There are many things to do, like updating the code base to the latest Freeplane and JabRef versions, developing a web-based version, or creating a new workspace concept. Of course, there is also lot’s of research to do. For instance, you could analyze how researchers are using mind-maps to manage literature, or work on modelling the user’s interests.

The Locations & Supervisors
Trinity College Dublin (TCD), Ireland / Prof. Joeran Beel
Trinity College Dublin is Ireland’s most prestigious university and among the top universities in Europe. It is located directly in the city center with a beautiful campus. Trinity College retains a tranquil collegiate atmosphere despite its location in the centre of a capital city (and despite it being one of the most significant tourist attractions in Dublin). This is in large part due to the compact design of the college, whose main buildings look inwards and are arranged in large quadrangles (called squares), and the existence of only a few public entrances .
Your supervisor at Trinity College Dublin will be Joeran Beel, founder of Docear and Mr. DLib. Joeran is Assistant Professor of Intelligent Systems in the school of computer science and statistics. He is also affiliated with the ADAPT Centre, which is a research centre closely cooperating with industry partners such as eBay, Intel, Microsoft, and PayPal. Joeran’s research focuses on recommender systems: recommendations as a service, recommender-system evaluation, and user modelling in the domain of digital libraries. Joeran has published three books and over 60 peer-reviewed papers, and has been awarded various grants for research projects, patent applications, and prototype development as well as some business start-up funding. He is involved in the development of several open-source projects such as Docear, Mr. DLib, JabRef, and Freeplane. Joeran founded two successful IT start-ups and received multiple awards and prizes for each. He studied and researched in Australia (Sydney), the US (Berkeley), Germany (Magdeburg & Konstanz), Cyprus (Nicosia) and England (Lancaster). He has a M.Sc. in Project Management, a M.Sc. in Business Information Systems and a Ph.D. in Computer Science. Prior to TCD, Joeran worked as IT product manager in the tourism industry (Munich, Germany), and as post-doctoral researcher at the National Institute of Informatics in Tokyo, Japan.
Dublin is the capital city of Ireland. Its vibrancy, nightlife and tourist attractions are renowned and it is the most popular entry point for international visitors to Ireland. It’s disproportionately large for the size of Ireland with nearly two million in the Greater Dublin Region – well over a third of the Republic’s population! The centre is, however, relatively small and can be navigated by foot, with most of the population living in suburbs. Being subject to the moderating effects of the Atlantic Ocean and the Gulf Stream, Dublin is known for its mild climate. Contrary to some popular perception, the city is not especially rainy. 
Konstanz University, Germany / Prof. Bela Gipp
The University of Konstanz (German: Universität Konstanz) is a university in the city of Konstanz in Baden-Württemberg, Germany. It was founded in 1966, and the main campus on the Gießberg was opened in 1972. The University is situated on the shore of Lake Constance just four kilometers from the Swiss border. As one of eleven German Excellence Universities, University of Konstanz is consistently ranked among the global top 250 by the Times Higher Education World University Rankings. In 2016 it was ranked 7th globally by the Times Higher Education 150 under 50 rankings. It is often referred to as “small Harvard” by the German media. 
Your supervisor at Konstanz University would be Bela Gipp. Bela Gipp serves as Juniorprofessor in Information Science at the University of Konstanz, Germany. Prior this, he was a post-doctoral researcher at the University of California Berkeley and at the National Institute of Informatics in Tokyo. From 2009 to 2013 he received an invitation from the University of California Berkeley, to conduct his doctoral research at the School of Information and the Department of Statistics, while being an external doctoral student at the University Magdeburg, Germany. He received his Ph.D. in Computer Science with distinction. His research interests are information retrieval and visualization, knowledge management systems and web technologies. His recent work focuses on developing semantic methods that analyze links, citations and other language independent characteristics to improve recommender systems and plagiarism detection software. He also researches the use of mind maps for different knowledge management tasks. He has published over 40 articles, three books and filed four patents. As a founder of SciPlore he develops the open-source software Docear. Starting at the age of 16, he won several prizes at Jugend Forscht, Germany’s premier youth science competition. The German Chancellor honored him after winning the 1st place in the state-level round three times in a row. Today, he acts as a jury member for Jugend Forscht. Scholarships allowed him to study abroad in Sydney, Beijing, and at UC Berkeley. After obtaining his Master of Science in Information Systems and a Master of Business Administration (MBA), he worked for the VLBA-lab, a joint venture of the SAP AG and the University Magdeburg. He has taught at the universities in Berkeley, Magdeburg and at the University of Applied Sciences HTW Berlin. He volunteered in rural China and India, teaching math and computer science, as well as at Syria’s Wadi International University. In his spare time he enjoys photography.
National Institute of Informatics (NII), Tokyo, Japan / Prof. Akiko Aizawa
The National Institute of Informatics (国立情報学研究所 Kokuritsu Jōhōgaku Kenkyūjo, NII) is a Japanese research institute created in April 2000 for the purpose of advancing the study of informatics. This institute is also devoted to creating a system to facilitate the spread of scientific information to the general public. The NII is the only comprehensive research institute in Japan in informatics. It also oversees and maintains a large, searchable information database on a variety of scientific and non-scientific topics called Webcat. 
Your supervisor at NII would be Prof. Akiko Aizawa (and Joeran Beel would be the co-supervisor). Akiko Aizawa is member of the Digital Content and Media Sciences Research Division at NII and works in the field of recommender systems, citation and content analysis as well as math retrieval. Akiko Aizawa has successfully supervised many students from the University of Konstanz and was also the supervisor of Joeran Beel and Bela Gipp during their time at NII.
