OntoMath 2.0 Ontology: Updates of the Formal Model
This paper is devoted to the problems of ontology-based mathematical
knowledge management and representation. The main attention is paid to the
development of a formal model for the representation of mathematical statements
in the Open Linked Data cloud. The proposed model is intended for applications
that extract mathematical facts from natural language mathematical texts and
represent these facts as Linked Open Data. The model is used in development of
a new version of the OntoMath ontology of professional
mathematics is described. OntoMath underlies a semantic
publishing platform, that takes as an input a collection of mathematical papers
in LaTeX format and builds their ontology-based Linked Open Data
representation. The semantic publishing platform, in turn, is a central
component of OntoMath digital ecosystem, an ecosystem of ontologies, text
analytics tools, and applications for mathematical knowledge management,
including semantic search for mathematical formulas and a recommender system
for mathematical papers. According to the new model, the ontology is organized
into three layers: a foundational ontology layer, a domain ontology layer and a
linguistic layer. The domain ontology layer contains language-independent math
concepts. The linguistic layer provides linguistic grounding for these
concepts, and the foundation ontology layer provides them with meta-ontological
annotations. The concepts are organized in two main hierarchies: the hierarchy
of objects and the hierarchy of reified relationships
Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)
The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers
Mathematical Services Composition
AbstractThis paper describes the definition and the use of a plan language in the context of mathematical web services. A plan is a document intended to describe how to use different mathematical web services to solve a particular problem. A plan is like a program in which most of the function calls have to be handled by web services. A plan is a multiple-state choreography document which could be either abstract, unresolved or resolved, depending on how much of the web services involved in the choreography is known. Such a plan can be instantiated into a composition language such as BPEL or to a mathematical routine (like a Maple routine) for execution

Towards a learner modelling engine for the Semantic Web
We describe XLM, the learner modelling subsystem of LEACTIVEMATH, from the viewpoint of how it makes use of technologies associated with the Semantic Web. We discuss how a better usage of these technologies could make of XLM a more generic learner modelling engine to serve a variety of elearning systems. We try to foresee important issues to be addressed and difficult problems to be solved in the way to this goal
