+---
+<p style="text-align:center;font-weight:bold" markdown="1">
+Workshop on Modular Knowledge (Tetrapod)<br/>
+Oxford, July 13, 2018<br/>
+at the [Federated Logic Conference 2018](http://www.floc2018.org/)<br/>
+affiliated with the [Third International Conference on Formal Structures for Computation and Deduction](http://www.cs.le.ac.uk/events/fscd2018/)
+</p>
+
+#### Description
+
+Mathematics, logics, and computer science support a rich ecosystem of formal knowledge.
+  This involves many interrelated human activities such as modeling phenomena and formulating conjectures, proofs, and computations, and organizing, interconnecting, visualizing, and applying this knowledge.
+  To handle the ever increasing body of knowledge, practitioners employ a rapidly expanding set of representation languages and computer-based tools centered around the four fundamental paradigms of formal deduction, computation, datasets, and informal narration.
+
+Modularity has been recognized in all FLoC-related communities as a critical method for designing scalable representation languages and building large corpora of knowledge.
+  It is also extremely valuable for comparing and exchanging knowledge across communities, corpora, and tools - a challenge that is both pressing and difficult.
+
+Expanding on the Tetrapod workshop at the conference on intelligent computer mathematics (CICM) 2016, this workshop brings together researchers from a diverse set of research areas in order to create a universal understanding of the challenges and solutions regarding highly structured knowledge bases.
+
+Of particular interest are
+* foundational principles such as theory graphs and colimits
+* interchange languages and module systems
+* languages and tools for representing, reasoning, computing, managing, and documenting modular knowledge bases
+
+#### Format
+
+- There will be 6 invited speakers, each of which will be asked to present a specific topic.
+- Each speaker will give a 15-minute presentation on that topic that is followed by a 
+     30-minute discussion session.
+- There will not be a call for papers or other contributions.
+     However, there will be a call for participation that will include the invited speakers and their topics.

+### Abstracts
+
+#### Modularity in Proof Checking (Catherine Dubois)
+The essence of (automated) proof checking is to check proofs for
+correctness. A proof checker takes a proposition and a presumed proof
+and merely verifies  the proof, checking it for correctness. It is
+much simpler to verify a proof than finding it. 
+Proof checking can be done in a batch way or interactively, as part of
+an interactive theorem prover. For example it is triggered in Coq by
+the keyword that ends a proof script (e.g. Qed or Defined). Moving
+proof checking outside of theorem provers is explored and implemented
+for example within the Dedukti system. Proof checking may also include
+some proof reconstruction.
+
+We may wonder why we need proof checking. First publications in
+mathematics or computer science may contain errors. Second automated
+theorem provers as complex software are buggy and thus verifying their
+answers and proofs is very important. Proof assistants are also complex
+software and having some independent proof checkers - off the shelves -
+may also help to reduce the trusted base instead of proving the code of
+proof assistants (which is an impossible task). Proof checkers are simpler
+software than interactive or automated proof tools. Their code can be
+reasonably
+checked by crossed-reviews for example.
+
+Type theory reduces the problem of proof checking to the problem of
+type-checking in a programming language. Thus a proof is a
+lambda-term, it is  a correct proof of a formula if its type is
+exactly the formula to be proven, thanks to the proofs-as-programs
+analogy. In our
+presentation, we'll focus on that definition/dimension of proof
+checking.
+
+Modular systems in computer science are divided into components or
+modules with
+well-defined interfaces and dependencies as small as
+possible. Modularity requires also mechanisms to
+compose/compile/assemble the
+components together to obtain an executable software.
+There is no doubt that proof checkers are modular software according to
+the previous
+definition. Let us go further and apply the feature of components/modules to
+proofs. We can distinguish internal modularity and external
+modularity. Internal modularity provides mechanisms to structure large
+proofs (e.g. modules, inheritance) while external modularity provides
+mechanisms to interface proofs having different origins and build
+'composite proofs'. I will illustrate external modularity with
+Dedukti and a proof of Erathostenes sieves made of a Coq component and
+a HOL component verified by the Dedukti proof checker.
+
+#### Modularity for specification, ontologies, and model-driven engineering (Till Mossakowski) (CANCELED)
+Within the fields of software specification, ontologies,
+model-driven engineering, and others, different notions of modularity
+have been studied. It turns out that a semantics of these
+artefacts can be both given in terms of logical theories, as well
+as in terms of model classes.
+
+Our central hypothesis is that a good support for modularity
+should one the hand support both the model-theoretic and
+theory-based point of view. On the other hand, it should be
+applicable to a wide variety of (logical) languages.
+
+The Distributed Ontology, Modeling and Specification
+Language (DOL), standardised by the OMG, aims at providing a
+unified metalanguage for meeting these criteria.
+
+#### What is a Module? (Natarajan Shankar)
+A module is a functional subsystem with an interface through which it
+interacts with other subsystems.  A module could be a body of
+knowledge or a theory (e.g., vector spaces), a biological subsystem
+(e.g., the nervous system), an organizational unit (e.g., accounting),
+a physical component (e.g., steering wheel), or a software component
+(e.g., compiler).  In computing, modules appear in specification
+languages like Z and PVS; modeling languages like B, TLA+, and SAL;
+and programming languages like Ada and ML.  Module mechanisms serve
+several different purposes: packaging and reuse of related
+functionality, abstraction and encapsulation of state and internal
+representations, separate compilation, and composition.  We discuss
+some of the principles underpinning the design of module systems and
+accompanying composition and reasoning principles.
+
+#### Modular Knowledge in Software Synthesis (Doug Smith)
+Software synthesis tools support the translation of requirements into acceptable software de-
+signs. The requirements may be expressed logically, with a deductive design process, or the
+requirements may come in the form of datasets, with an inductive design process. This session
+focuses on modularity in software synthesis, and in particular on modular knowledge about re-
+quirements, software design, and the structure of the design process. We briefly outline some of
+the key forms of modularization that arise in these aspects of software synthesis.
+
+1 - Requirements
+
+For applications where mathematical correctness is important, requirements and high-level
+designs can be structured using formal logical specifications as finite presentations of theo-
+ries, which are composed using specification morphisms and colimits. For machine learning
+applications, the requirements come in form of structured data sets.
+
+2 - Software Design Knowledge
+
+Representations of software design knowledge allow developers to guide an automated synthe-
+sis system so that it can effectively translate requirement-level specifications into acceptable
+high-level designs. Transformations (replace specification or code patterns by other code
+patterns) and inference rules that relate logical goals with program structure (e.g. deduc-
+tive synthesis rules) provide some of the basic design knowledge modules for any synthesis
+system. Larger grain modules can capture reusable higher-level design knowledge: algorithm
+design theories, datatype specifications and refinements, formalized design patterns, and
+architectural patterns. These are used with deductive/refinement techniques to generate ini-
+tial designs from requirement-level specifications. Machine learning applications also exploit
+larger-grain patterns, such as linear regression models and neural networks. These provide a
+computation pattern (with parameters to-be-learned and chosen hyperparameters) that can
+be instantiated using methods for fitting models to the given data. More ad-hoc forms of de-
+sign knowledge include sketches, program templates, and schemata. These are used with (1)
+deductive/refinement techniques to generate instantiations from logical specifications, or (2)
+inductive generalization techniques that search a space of instances given concrete examples.
+
+3 - Derivations
+
+A software synthesis process that generates interesting software usually involves the compo-
+sition of many kinds of design knowledge and so it is relevant to consider the structuring of
+that composition, called a derivation. Derivations can be a sequence (or tree) of specifications
+where each is derived from its predecessor by applying a module of design knowledge. Typ-
+ically, the early knowledge applications in a derivation introduce the overall algorithmic or
+architectural structure and then many more knowledge applications are applied to improve
+performance and to fit the design to the target computational substrate.
+
+#### Modularity in Mathematical Computation (Nicolas Thiery)
+Over the last decades, a huge amount of computational software was
+developed for pure mathematics, in particular to support research and
+education. As for any complex ecosystem of software components, the
+ability to compose them has a multiplier effect on the expressive
+power, flexibility, and range of applications.
+
+The purpose of this session is to share experience on the many
+barriers to composability in computational mathematics, and how they
+are being tackled in various communities. Of particular interest will
+be the exploitation of knowledge to leverage some of the barriers.
+feedback from neighbor fields (proofs, data, knowledge) will be most
+welcome.

+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.
 
+##### 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
+After having been associated with the KWARC research group at Jacobs University Bremen
+under guidance of Prof.Dr. Michael Kohlhase (I know the name coincidence is amazing ...)
+for a couple of years, since July 2011 I'm actually a working member of the group. Before
+I worked at the Safe-and-Secure-Systems department at DFKI (German Research Institue for
+Artificial Intelligence) in Bremen. Inbetween I have been "lent" to zbMATH (Zentralblatt
+Mathematik, Berlin) for a design study about search interfaces for mathematicians.
+
+I am still very fond of my previous research group [dimeb](http://www.dimeb.de)
+(Digital Media in Education) at the University of Bremen under guidance of Prof. Dr. Heidi
+Schelhowe.
+
+### Research Focus
+My research interest lies in the intersection between the fields of "Semantic
+Web" and "Human-Computer-Interaction", especially Interaction Design for semantic data
+("Semantic Interaction Design"), with a focus on educational environments. I have
+developed the software system [CPoint](http://www.kwarc.info/projects/CPoint/),
+an invasive, semantic work environment in MS PowerPoint, which allows to enrich PPT
+documents semantically, which makes use of all this great semantic added-value
+information, and which provides conversion facilities for transcribing such semantically
+enhanced PPT documents into [OMDoc](http://www.omdoc.org) files.
+
+I developed the SACHS project, in which we built an invasive, semantic help system for the
+DFKI-internal Controlling System in MS Excel. Some prototypically implemented semantic
+interactions turned out to be quite nice, for example, "semantic navigation".
+
+At the moment I work for the SiSsI project, in which we explore some more
+human-spreadsheet interactions and decouple our semantic services from specific
+spreadsheet players like MS Excel.
+
+At the end of last year I started to make use of Kelly's Repertory Grid Technique. The
+example data set for the MathUI'13 paper you can find [here](http://www.kwarc.info/ako/ProcrustesAnalysis).
