  • Documents with Flexible Notation Contexts As Interfaces To
    Documents with flexible Notation Contexts as Interfaces to Mathematical Knowledge Michael Kohlhase, Christine Muller,¨ Normen Muller¨ Computer Science, Jacobs University Bremen, Germany m.kohlhase/c.mueller/[email protected] In this paper we explore the use of documents as interfaces to mathematical knowledge. We propose an augmented document model that facilitates the explication of a document’s notation context, i.e. the selection of appropriate presentations for all symbols in the docu- ment. By separating the notation context from the structure and content of a document, we aim at identifying the author’s selection of notation, i.e. his notation practices. This facili- tates both, the identification of communities of practice (COP) that share specific notation preferences and, conversely, the adaptation of documents to the notation preferences of iden- tified COPs, e.g. groups of readers and co-authors. Furthermore, explicating a document’s notation context allows for referencing and, particularly, reusing contexts, which reduces the author’s workload during the authoring process. 1 Introduction In this paper we will re-evaluate the concept of a document in the age of digital media. Since the development of writing, documents have become one of the primary means of passing on knowledge. If we take the view that knowledge is a state of the (human) mind where concepts and experiences are highly interlinked, and interpret “documents” broadly to include spoken language or action sequences played out1, then we can see that documents are almost the only means to communicate knowledge: quite literally, documents are interfaces to knowledge. Here, we will look at mathematical documents as interfaces to mathematical knowledge, since they have special complexities that reveal the underlying nature of documents and knowledge.

  • Towards a Mizar Mathematical Library in Omdoc Format
    STUDIES IN LOGIC, GRAMMAR AND RHETORIC 10 (23) 2007 Towards a Mizar Mathematical Library in OMDoc Format Grzegorz Bancereki and Michael Kohlhaseii i Technical University Bialystok, [email protected] ii Jacobs University Bremen, [email protected] Abstract. Mizar is one of largest libraries of formalized mathematics. The language of the library is highly optimized for authoring by humans. Like in natural languages, the meaning of an expression is influenced by its (mathematical) context in a way that is natural to humans, but hard to specify for machine manipulation. From this point of view, it may be considered as locked up in an arcane file format. Indeed, the Mizar system itself is currently the only system that can reliably operate on the Mizar library. This paper presents an experiment of using the Mizar system to trans- form the Mizar library into the OMDoc format (Open Mathematical Documents), an XML-based representation format for mathematical knowl- edge that is geared towards making formula structure and context depen- dencies explicit. We expect the result of this experiment: an OMDoc version of the Mizar library to enhance system support for formal mathematical libraries. 1 Introduction In the last years we have seen the birth of a new research area: “Mathemat- ical Knowledge Management” (MKM), which is concerned with representation formalisms for mathematical knowledge, such as MathML [2], OpenMath [9] or OMDoc [16], mathematical content management systems [12, 1, 5], search en- gines [24, 23, 19, 15, 10], as well as publication and education systems [18,20] for mathematics. The perceived interest in the domain of general knowledge manage- ment tools applied to mathematics is that mathematics is a very well-structured and well-conceptualized subject.

  • STEXIDE: an Integrated Development Environment for STEX Collections
    STEXIDE: An Integrated Development Environment for STEX Collections Constantin Jucovschi and Michael Kohlhase Computer Science, Jacobs University Bremen fc.jucovschi,[email protected] Abstract. 1 Authoring documents in MKM formats like OMDoc is a very tedious task. After years of working on a semantically annotated corpus of STEX documents (GenCS), we identified a set of common, time- consuming subtasks, which can be supported in an integrated authoring environment. We have adapted the modular Eclipse IDE into STEXIDE, an author- ing solution for enhancing productivity in contributing to STEX based corpora. STEXIDEsupports context-aware command completion, module management, semantic macro retrieval, and theory graph navigation. 1 Introduction Before we can manage mathematical `knowledge' | i.e. reuse and restructure it, adapt its presentation to new situations, semi-automatically prove conjectures, search it for theorems applicable to a given problem, or conjecture representation theorems, we have to convert informal knowledge into machine-oriented repre- sentations. How exactly to support this formalization process so that it becomes as effortless as possible is one of the main unsolved problems of MKM. Currently most mathematical knowledge is available in the form of LATEX-encoded docu- ments. To tap this reservoir we have developed the STEX [Koh08,sTe09] format, a variant of LATEX that is geared towards marking up the semantic structure underlying a mathematical document. In the last years, we have used STEX in two larger case studies. In the first one, the second author has accumulated a large corpus of teaching materials, comprising more than 2,000 slides, about 800 homework problems, and hun- dreds of pages of course notes, all written in STEX.

  • The Planetary Project: Towards Emath3. 0
    The Planetary Project: Towards eMath3.0 Michael Kohlhase { for the Planetary Group Computer Science, Jacobs University Bremen, Germany http://planetary.mathweb.org Abstract. The Planetary project develops a general framework { the Planetary system { for social semantic portals that support users in interacting with STEM (Science/Technology/Engineering/Mathematics) documents. Developed from an initial attempt to replace the aging portal of PlanetMath.org with a mashup of existing MKM technologies, the Planetary system is now in a state, where it can serve as a basis for various eMath3.0 portals, ranging from eLearning systems over scientific archives to semantic help systems. The Planetary project aims at developing a general framework { the Plan- etary system { for social semantic portals that support users in interacting with STEM documents. It is carried by enthusiasts from Jacobs University and The Open University. Main Concepts and Project Genesis Work on the Planetary system was triggered in August 2010 by the real- ization that the KWARC group at Jacobs University had developed semantic counterparts of much of the components underlying the PlanetMath portal [Pla]. PlanetMath.org is an online community that creates and manages an encyclo- pedia of mathematical concepts; hundreds of regular contributors have pub- lished about 8500 encyclopedia entries called articles. PlanetMath was founded in 2000; even before Wikipedia, and is thus one of the first Web2.0 systems. The No¨ospheresystem [Noo] underlying the portal { essentially a LATEX-based Wiki implemented in Perl { is showing its age and becoming hard to manage. We felt that extending Planetmath to an eMath3.0 system { a social semantic web platform for Mathematics { via MKM technologies, might breathe additional life into the PlanetMath community and at the same time serve as a showcase of arXiv:1206.5048v1 [cs.DL] 22 Jun 2012 MKM technologies into the mathematics community.
