The ability to *represent knowledge about the world* and to *draw logical inferences* is one of the central components of intelligent behavior, as a consequence, reasoning components of some form are at the heart of many artificial intelligence systems.
#### Research
The KWARC research group conducts research in knowledge representation and reasoning techniques with a view towards applications in knowledge management.
We extend techniques from [formal methods](http://kwarc.info/semantics.html#fm) 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](http://kwarc.info/semantics.html#ssem) in technical documents.
This level of markup allows for offering interesting [knowledge management services](http://kwarc.info/projects/) without forcing the author to formalize the document contents.
## Recent News ([see all](/news/))
##### Approach: Corpus-based Meta-Mathematics
In this title we have three components that warrant explanation:
1. **Mathematics**: we use the mathematical knowledge and mathematical documents as a test
tube for our research as the knowledge and document structures are quite explicit and
overt and the content of mathematics is well-understood. Anything that has the same
properties we consider to be "mathematics" as well.
2. **Meta**: we develop Meta-Artefacts, i.e. we
* design **representation languages** (logics) that allow to talk *about* mathematical objects,
their properties, and relations,
* invent **algorithms** that analyze and transform these representations, and
* implement them in **end-user systems** that utilize both.
3. **Corpus-based**: we do this as a natural science by looking at data (i.e. corpora of
documents and formalizations).
##### KWARC Process
We approach Corpus-Based Meta-Mathematics (iteratively) in three steps:
1. **Analysis**: we analyze the corpora for patterns and structures.
2. **Synthesis**: we design and build meta-artefacts (languages, algorithms, and systems)
and derive data sets from the corpora.
3. **Experimentation**: we evaluate the representation languages and algorithms on the
corpora and the systems on end users (mathematicians).

### Description
I am a software engineer and has worked on products such as Adobe Illustrator, Google Maps and Google Pay. I am passionate about organizing knowledge from different perspectives in a way that allows readers to effortlessly see all kinds of justifications for and against any claim. To further this goal, I started Sophize Foundation, a non-profit that is currently working towards building an open state-of-the-art [Mathematics library](https://sophize.org).
### Research Focus
As a KWARCie, I am very excited to help build systems and interfaces that will generate and present educational material tailored to each learner's specific needs.

### Description
I am a master student at [FAU Erlangen-Nürnberg](http://www.fau.de). Currently I am working on my master thesis at the [KWARC group](http://kwarc.info) and got employed there as a Hiwi to help with the AI-1 lecture.
In 2015 I started studying Computer Science at [FAU Erlangen-Nürnberg](http://www.fau.de). While finishing my bachelor's degree I visited some master courses. My main interests are optimization and artificial intelligence. Also, I am very interested in knowledge management and gaining new knowledge.
### Current Work
My master thesis is about the formalization of set theory in [KWARC's MMT system](https://kwarc.info/systems/mmt/). To achieve this goal I use some old formalizations of set theory in Twelf. Since I just started the exact course of my master thesis is still unclarified.
My work as a Hiwi mostly consists of cutting old lecture videos to make online lectures more attractive for students. Also, I give advice and help to come up with good questions for the students.

I completed my [BSc](https://svn.eecs.jacobs-university.de/svn/eecs/archive/bsc-2009/dginev.pdf) in 2009, my [MSc](http://old.kwarc.info/people/dginev/publications/DeyanGinev_MScThesis.pdf) in 2011 and am currently pursuing a [PhD degree](https://svn.kwarc.info/repos/dginev/public/DeyanGinev_PhD_proposal.pdf).
My initial work was focused at the arXMLiv effort for converting the Cornell e-Print
archive from TeX to HTML. It has since expanded to the
[sTeX](https://github.com/KWARC/sTeX) (a semantically enriched authoring toolkit for
LaTeX) and [LLaMaPUn](https://github.com/KWARC/LLaMaPUn) projects (NLP and Data Mining on
STEM scientific publications).

My main focus is to enhance the representation of mathematical expressions in DLMF, improving their accessibility, computational semantics, and enabling further reuse in a broader class of applications.

### Abridged Bio
Bulgarian 🇧🇬
### Research Focus
My primary interest lies in Mathematical Knowledge Management and Computational Semantics of Natural Language, with a focus on Underspecification and Ambiguity in the Math domain.
I was a student at KWARC between 2007-2011, under Prof. Dr. Michael Kohlhase. I completed my MSc in 2011, at Jacobs University Bremen. Since then I have been enrolled as a PhD student, now at FAU Erlangen-Nürnberg.
I am also involved in and excited by the problems of Scalable Software Architectures, Data Mining, Processing in the Large and the Semantic Web.
In 2012, I first visited the United States as a guest researcher at NIST's Gaithersburg campus. I had a chance to do three of those visits until 2014.
My current work is targeting large-scale Semantic Enrichment of informal mathematical documents, based on the [arXiv](https://arxiv.org) corpus. For a more detailed view, feel free to read my [PhD Proposal](https://svn.kwarc.info/repos/dginev/public/DeyanGinev_PhD_proposal.pdf).
I spent 2014-2017 as the first hire of [Authorea](https://www.authorea.com/) in New York. The three years as a "full stack developer" at a startup were a triple espresso of realism. Authorea has since been acquired by the Wiley publishing company. I learned a great deal!
In 2018, I returned to my work with LaTeXML, which is what I continue to date. We have made great strides in some regards, notably the recent announcement of [the ar5iv project](https://twitter.com/dginev/status/1488157927001268231) and its subsequent adoption as an [arXiv Lab](https://blog.arxiv.org/2022/02/21/arxiv-articles-as-responsive-web-pages/) at Cornell. I am happy to now also be a registered volunteer contributor with Cornell University, as the "virtual head" of the ar5iv Lab.
###non-academic professional profile
please visit my [personal website](http://prodg.org).
In 2021, I joined the [W3C Math](https://www.w3.org/Math/) working group, as a NIST-endorsed independent expert.
My PhD journey is now spanning two continents and over a decade. In 2022, I am in the final write-up phase for completing the degree with Michael.
At present, I reside in New York City, next to the campus of Rockefeller University. I can see the arXiv office at Cornell Tech from my window, which was a completely unplanned - yet delightful! - accident of life.
