Use Omdoc Representing Geometric Algebra Use OMDoc Representing Geometric Algebra Author: Michael Watts Jr. and Ratish Shrestha Faculty Advisor: Dr. Kuo-pao Yang and Dr. Wendy Zhang Department: Computer Science and Industrial Technology INTRODUCTION OMDoc ( Open Mathematical Document ) is an XML based markup language used to represent mathematical documents and complex theory in a very easy and understandable manner. OMDoc has been developed by a German mathematician and computer scientist Michael Kohlhase since 1998 and has already released different versions of OMDoc specifications. OMDoc can be used to represent mathematical formulae and it supports content dictionaries containing the definitions of the symbols used in formulae. OMDoc provides an infrastructure for the communication and storage of mathematical knowledge. OMDoc extends OpenMath and MathML standard formats by creating markup for documents and theory level of mathematical documents. The document author can specify them in a formal way and publish it on the Web site and people using the document can take advantage of them. OMDoc uses three levels of modeling to represent a mathematical document. a) Mathematical Theory: At this level, OMDoc supplies original markup for clustering sets of statements into theories. b) Mathematical Statement: OMDoc provides original markup infrastructure for making the structure of mathematical statements explicit. c) Mathematical Formulae: At the level of mathematical formulae, OMDoc uses the established standards OpenMath [BCC+04] and Content-MathML [ABC+03]. Mathematical knowledge can be vary greatly in its presentation and its level of formality, but its semantic structure is common to all forms of mathematics. OMDoc markup language can present the common semantic structure and exchange structured mathematical documents between different systems and software. PROPOSED RESEARCH The proposed research is to develop OMDoc format documents to represent mathematical expressions in the book “Clifford Algebra to Geometric Calculus” by David Hestenes and Garret Sobczyk. Clifford Algebra is an associative algebra that contains vector space with a quadratic form. Clifford Algebra can be used to generalize the representation of Complex numbers. In this research, we will be representing Geometric Algebra that is defined by a set of axioms that explain the definitions and identities of different properties. By this way, we can use OMDoc format XML documents to develop a content dictionary of definitions and their meaning to make it a versatile and efficient computational tool. METHOD We plan on using Cygwin and QMath to write most of the OMDoc and an editor such as Altova® XMLSpy® to edit the XML as needed. We will be using these tools to create informative examples and formulas to the user based on the information provided in the Clifford Algebra to Geometric Calculus book. COLLABORATION WITH FACULTY SPONSOR Dr. Wendy Zhang, Associate Professor, is the sponsor for this project together with co- sponsor Dr. Kuo-pao Yang, Assistant Professor. They have provided all the necessary information about OMDoc, its documentations and examples. We will be working together in the representation of the Clifford Algebra into OMDoc format. Faculty sponsors and students will meet once a week to ensure the progress of the project. IMPACT OF PROJECT We are aiming to build a library of mathematical definitions of axioms used in Clifford Algebra. This library will be stored in a web repository that can be accessed by anyone in the Internet and use is to represent different mathematical expressions and definitions. We also plan to write a paper based on the research of this project and submit it to Consortium for Computing Sciences in Colleges (CCSC) Conference 2009 for publication. OVERALL VALUE OF PROJECT TO STUDENT’S LEARNING We will be learning a new type of XML based markup language called OMDoc. This markup language will provide us knowledge about how to express mathematical expressions as well as its different applications. We will also be familiar with different technologies used by developers around the world who are working in similar projects. Since OMDoc has been used in various projects and developers are continuously using it for new technologies, we will get ideas about the applications of OMDoc in other different field of mathematics. CAPABILITY OF STUDENTS TO COMPLETE PROJECT Michael Watts is a third year student at Southeastern Louisiana University. He’s been involved in web development since a young age and has taken courses in Software Engineering and Web Development. His knowledge of XML markup will contribute to the project. Ratish Shrestha, a senior computer student, has taken computer science courses such as Theory of Numerical Methods, Web Programming, and Software Engineering that are helpful in the success of this project. Currently, he has been working for Southeastern Web Team as a Web Programmer Intern. He can use his experience as a Web Programmer and contribute his efforts to this project. FEASIBILITY OF PROJECT TO BE COMPLETED WITH AVAILABLE RESOURCES Our faculty sponsor will provide us space to work in the lab of Computer Science department. We do not need to travel places for this project. We will be using computers extensively that has access to the Internet. This project is based primarily on Open Source environment, so we do not need to buy most of the required software. We can download much of the software, including Cygwin, QMath, and some basic editors from the Internet for free. A more feature-filled editor will require more funding, which we believe will speed the project as well as increase the accuracy of our results. BUDGET JUSTIFICATION The total funds requested for our project equal $1,000.00. Our project requires Operating Expenses include two copies of “Clifford Algebra to Geometric Calculus: A Unified Language for Mathematics and Physics”, by Hestenes and Garret Sobczyk are requested for purchase to use for the project ($125.00 x 2 = $250).

  • A Framework for Semantic Publishing of Modular Content Objects
    A Framework for Semantic Publishing of Modular Content Objects Catalin David, Deyan Ginev, Michael Kohlhase, Bogdan Matican, Stefan Mirea Computer Science, Jacobs University, Germany; http://kwarc.info/ Abstract. We present the Active Documents approach to semantic pub- lishing (semantically annotated documents associated with a content commons that holds the background ontologies) and the Planetary system (as an active document player). In this paper we explore the interaction of content object reuse and context sensitivity in the presentation process that transforms content modules to active documents. We propose a \separate compilation and dynamic linking" regime that makes semantic publishing of highly struc- tured content representations into active documents tractable and show how this is realized in the Planetary system. 1 Introduction Semantic publication can range from merely equipping published documents with RDFa annotations, expressing metadata or inter-paper links, to frame- works that support the provisioning of user-adapted documents from content representations and instrumenting them with interactions based on the seman- tic information embedded in the content forms. We want to propose an entry to the latter category in this paper. Our framework is based on semantically anno- tated documents together with semantic background ontologies (which we call the content commons). This information can then be used by user-visible, se- mantic services like program (fragment) execution, computation, visualization, navigation, information aggregation and information retrieval (see Figure 5). Finally a document player application can embed these services to make docu- ments executable. We call this framework the Active Documents Paradigm (ADP), since documents can also actively adapt to user preferences and envi- ronment rather than only executing services upon user request.

  • Importing the OEIS Library Into Omdoc
    Importing the OEIS library into OMDoc Enxhell Luzhnica, Mihnea Iancu, Michael Kohlhase Computer Science, Jacobs University, Bremen, Germany [email protected] Abstract. The On-line Encyclopedia of Integer Sequences (OEIS) is the largest database of its kind and an important resource for mathematicians. The database is well-structured and rich in mathematical content but is informal in nature so knowledge management services are not directly applicable. In this paper we provide a partial parser for the OEIS that leverages the fact that, in practice, the syntax used in its formulas is fairly regular. Then, we import the result into OMDoc to make the OEIS accessible to OMDoc-based knowledge management applications. We exemplify this with a formula search application based on the MathWebSearch system. 1 Introduction Integer sequences are important mathematical objects that appear in many areas of math- ematics and science and are studied in their own right. The On-line Encyclopedia of Integer Sequences (OEIS) [6] is a publicly accessible, searchable database documenting such sequences and collecting knowledge about them. The effort was started in 1964 by N. J. A. Sloane and led to a book [10] describing 2372 sequences which was later extended to over 5000 in [11]. The online version [8] started in 1994 and currently con- tains over 250000 documents from thousands of contributors with 15000 new entries being added each year [9]. Documents contain varied information about each sequence such as the beginning of the sequence, its name or description, formulas describing it, or computer programs in various languages for generating it.

Abstract The interoperability of proof assistants and the integration of their li- braries is a highly valued but elusive goal in the field of theorem proving. As a preparatory step, in previous work, we translated the libraries of multiple proof assistants, specifically the ones of Coq, HOL Light, IMPS, Isabelle, Mizar, and PVS into a universal format: OMDoc/MMT. Each translation presented tremendous theoretical, technical, and social chal- lenges, some universal and some system-specific, some solvable and some still open. In this paper, we survey these challenges and compare and evaluate the solutions we chose. We believe similar library translations will be an essential part of any future system interoperability solution and our experiences will prove valuable to others undertaking such efforts. 1 Introduction Motivation The hugely influential QED manifesto [2] of 1994 urged the automated reasoning community to work towards a universal, computer-based database of all mathematical knowledge, strictly formalized in logic and supported by proofs that can be checked mechanically. The QED database was intended as a communal re- source that would guide research and allow the evaluation of automated reasoning tools and systems. This database was never realized, but the interoperability of proof assistants and the integration of their libraries has remained a highly valued but elusive goal. This is despite the large and growing need for more integrated and easily reusable libraries of formalizations. For example, the Flyspeck project [20] build a formal proof of the Kepler conjecture in HOL Light.

  • 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.

  • Wiki Authoring and Semantics of Mathematical Document Structure
    Wiki Authoring and Semantics of Mathematical Document Structure Hiraku Kuroda∗ and Takao Namiki Department of Mathematics, Hokkaido University, 060-0810 Sapporo, Japan Abstract We are developing a CMS including document authoring feature based on wiki to publish struc- tural mathematical documents on the Web. Using this system, users can write documents including mathematical expressions written in LATEX notation and explicitly stated characteristic structures of mathematical articles such as definitions, theorems, and proofs. Documents input to the system is published on the Web as not only XHTML files to be browsed but also XML files complying with NLM-DTD, which is used to exchange articles electronically. Not only single wiki page document, users can build a document which consist of more than one pages and is described its structure se- mantically by the system. In order to do this, we also propose an application of OAI-ORE and RDF vocabularies to describe structures of documents consisting of several resources. 1 Introduction Today, many documents are published on the Web. The term “documents” here includes articles of news or blog, wiki pages, journal articles, and any other web pages. These documents are published as HTML or XHTML to be browsed, or as PDF or PS file to be printed out. Sometimes one document is published as several formats. Some documents consist of several resources. One of examples is a document including a graphic image. Here, we assume that body text of the document is written in a HTML file and the image is a JPG file. On the Web, each of them is independent resource and given unique URI.

  • A Semantic Wiki for Mathematical Knowledge Management
    SWiM – A Semantic Wiki for Mathematical Knowledge Management Christoph Lange Computer Science, Jacobs University Bremen, [email protected] Abstract. SWiM is a semantic wiki for collaboratively building, edit- ing and browsing mathematical knowledge represented in the domain- specific structural semantic markup language OMDoc. It motivates users to contribute to collections of mathematical knowledge by instantly shar- ing the benefits of knowledge-powered services with them. SWiM is cur- rently being used for authoring content dictionaries, i. e. collections of uniquely identified mathematical symbols, and prepared for managing a large-scale proof formalisation effort. 1 Research Background and Application Context: Mathematical Knowledge Management A great deal of scientific work consists of collaboratively authoring documents— taking down first hypotheses, commenting on results of experiments, circulating informal drafts inside a working group, and structuring, annotating, or reor- ganising existing items of knowledge, finally leading to the publication of a well-structured article or book. Here, we particularly focus on the domain of mathematics and on tools that support collaborative authoring by utilising the knowledge contained in the documents. In recent years, several semantic markup languages have been developed to represent the clearly defined and hi- erarchical structures of mathematics. The XML languages MathML [9], Open- Math [11], and OMDoc [3] particularly aim at exchanging mathematical knowl- edge on the web. OMDoc, employing Content MathML or OpenMath repre- senting the functional structure of mathematical formulæ—as opposed to their visual appearance—and adding support for mathematical statements (like sym- arXiv:1003.5196v1 [cs.DL] 26 Mar 2010 bol declarations or axioms) and theories, has many applications in publishing, education, research, and data exchange [3, chap.
