Many of the KWARC projects are the work of students and become orphaned when these move on
to greener pastures (e.g. when they graduate). We put these systems up for adoption bt new
students. If you are interested, please contact someone from the KWARC group, we would be
happy to help you understand the development opportunities and get involved.

MMT is a framework for representing declarative languages such as logics, type theories, set theories, etc.. It achieves a high level of generality by systematically avoiding a commitment to a particular syntax or semantics. Instead, individual language features (e.g., λ-abstraction, conjunction, etc.) and syntax features (keywords, notations, etc.) are defined as separate, reusable modules, from which individual languages are assembled. These modules can be declarative by specifying features as Mmt theories or programmatic by providing individual rules as plugins.Despite this high degree of abstraction, it is possible to implement advanced algorithms generically at the MMT level. These include knowledge management algorithms (e.g, IDE, search, change management) as well as logical algorithms (e.g., parsing, type reconstruction, module system). Thus, we can use MMT to obtain strong implementations of declarative languages at extremely low cost.Moreover, the focus on modularity and language-independence enables system integration, where MMT can mediate the exchange of knowledge across different foundational systems and concrete syntaxes.See here for the MMT homepage.

The MathWebSearch system (MWS) is a content-based search engine for mathematical
formulae. It indexes MathML formulae, using a technique derived from automated theorem
proving: Substitution Tree Indexing. Find more information at the
[Project Overview Page](http://search.mathweb.org) or the
[GitHub Repository](http://githhub.com/KWARC/mws).
proving: Substitution Tree Indexing. With this indexing technique MWS can answer
unification queries extremely efficiently (30-100 ms) on large sets of formulae (in the
Gigaformula range); but the index (up to 50GiB) needs to be kept in main memory.
MWS is the [formula search engine](https://zbmath.org/formulae/) employed in
[Zentralblatt Math](http://zbmath.org); see a
[demo on a mathematical subset](http://arxivsearch.mathweb.org) of the
[arXMLiv data set](/projects/arXMLiv/) [further demos](http://search.mathweb.org).
The MathWebSearch system is Open Source,
[developed on GitHub](https://github.com/MathWebSearch), and is (by now) easily deployable via
a set of docker containers. We can give your project a search interface like the
[nLab search](https://nlabsearch.mathweb.org/) for [nLab](https://ncatlab.org/) at the
cost of theming the [user interface](https://github.com/MathWebSearch/frontend) and
[building a harvester](https://github.com/MathWebSearch/nlab_harvester).

OMDoc is a markup format and data model for Open Mathematical Documents. It serves as
semantics-oriented representation format and ontology language for mathematical
knowledge. The formal part of OMDoc has been refined into the
[MMT format](https://uniformal.github.com), and we use the
[MMT System](https://uniformal.github.com) as the reference implementation.
We are currently working on extending MMT to cover the full flexiformal coverage of
OMDoc.

Different layouts and highlighting settings are available to visualize the complex theory graphs efficiently.
In particular, this allows exploration of big mathematical libraries, e.g, those related to theorem provers like Coq or Isabelle.
Furthermore, we have a virtual reality protoype to allow intuitive and immersive interactions.

taught: WS16/17, SS16

The KWARC group (Wissensrepräsentation und Verarbeitung)conducts research in knowledge representation and reasoning techniques with a view towards applications in knowledge management.
We extend techniques from formal methods so that they can be used in settings where formalization is either infeasible or too costly.
We concentrate on developing techniques for marking up the structural semantics in technical documents.
This level of markup allows for offering interesting knowledge management services without forcing theauthor to formalize the document contents.
In contrast to courses with fixed topics, project topics are defined individually.
See the [KWARC home page](http://kwarc.info) for a general introduction to the research and [the KWARC research topics list](http://gl.kwarc.info/kwarc/thesis-projects) for expemplary topics.
