Internal note for our chair: each of us should offer / provide 12 months of supervision every year. Each thesis or project "counts" just like it counts for the students, where #months = #ECTS / 4. That is, B.Sc. project = 6 ECTS = 1.5 months, M.Sc. project = 16 ECTS = 4 months, B.Sc. thesis = 12 ECTS = 3 months, M.Sc. thesis = 25 ECTS = 6 months.
Internal note to thesis supervisors: you need to make sure that each supervised thesis appears on our chair homepage. For this you need to: 1) put the final PDFs of the thesis and the presentation into /nfs/raid3/publications/theses - please follow the existing naming convention!; the PDFs will be available at http://ad-publications.informatik.uni-freiburg.de/theses/<PDF> 2) send a mail to Sabine with the following information: title of thesis, name of student, thesis abstract, link to thesis PDF, link to presentation PDF.
List of available and ongoing topics for current B.Sc. and M.Sc. projects and theses
Note to interested students: if all projects in this list are ongoing, this means that our current capacity for supervising projects and theses is reached. Maybe, if you come back later, there will be an offer again. You can also propose a topic on your own.
Movie Search (thesis, ongoing): Our semantic search engine Broccoli answers semantic queries. Queries can, in theory, be very complex and powerful. However, it is almost impossible for inexperienced users to build appropriate structured queries. Goal of this thesis is to apply and adapt the search paradigm behind Broccoli to a narrow domain. Think of a search for movies where you can search by all the common things, i.e. actors, the director, year, genre, but also by keyword search in the plot. However, for plot search, Broccoli features can come in handy. Looking for the movie where the charcter played by Di Caprio has drug problems? Linking the characters in the plot to knowledge-base entries can help a lot. For this thesis you will deal with many aspects that make the thesis far more researchy than technical. What is a good set of features to support? How can you achive a good user experience? Where to get good data about movies (structured and plots)? Does it make sense to take general knowledge data (like that from Broccoli) and link it to the data about the movies? It may be necessary at some point to add new operations to Broccoli. It would be good if you were experienced in (or willing to pick up) multiple programming languages. Between data integration, user interfaces and Brococli server code, it really makes sense to pick a suitable languge for each job. supervised by Björn Buchhold
Efficient code for (de)compression (project, ongoing): Our semantic search engine Broccoli and its successor (under development) work with compressed lists a lot. Current implementations are fast but far from optimal and have never been compared to other available compression schemes. Goal of the project is to tune the current (C++) implementation for speed, to evaluate the literature for promising alternatives and to compare them. supervised by Björn Buchhold
Question Answering using Semantic Full-Text Search (thesis, available): Use our semantic full-text search engine Broccoli for the FACTOID and LIST questions from one of the TREC Questions Answering benchmarks, e.g. http://trec.nist.gov/data/qa/2006_qadata/QA2006_testset.xml . What is the performance of manually constructed queries, and what can be done to improve it? Good if you heard the information retrieval lecture before, but not absolutely necessary ... supervised by Hannah Bast and [Elmar or Björn]
An easy-to-use web app for the CompleteSearch engine (project, available): The CompleteSearch engine complex search capabilities (including prefix search and faceted search) on semi-structured data (text and databases) with very fast query times. Our current software is powerful and flexible, but has quite a learning curve before it can be used. The goal of this project would be to set up a web app, where one can upload any CSV dataset, and then have a convenient search (with meaningful default settings), without having to set up anything oneself. This would be an extremely useful web application ... supervised by Hannah Bast
PDF to TeX Parser (project or thesis, ongoing): Per default, you can't rearrange or edit texts in PDF files. As long as you don't have the TeX sources of a PDF, there is no chance to edit the PDF: While creating a PDF from TeX file(s) is a quite common feature, the other way around - recovering the TeX source(s) from given PDF(s) - isn't. The goal of this project is to implement a parser that produces TeX sources from given PDF files to be able to edit the sources and to recompile them to a new PDF ... also available as master thesis if combined with the topic "Formula recognition in PDF files" (see below) ... supervised by Claudius Korzen
