Abstract. This paper is motivated by the massively increasing structured data on the Web (Data Web), and the need for novel methods to exploit these data to their full potential. Building on the remarkable success of Web 2.0 mashups, this paper regards the internet as a database, where each web data source is seen as a table, and a mashup is seen as a query over these sources. We propose a data mashup language, which allows people to intuitively query and mash up structured and linked data on the web. Unlike existing query methods, the novelty of MashQL is that it allows people to navigate, query, and mash up a data source(s) without any prior knowledge about its schema, vocabulary, or technical details. We even do not assume even that a data source should an online or inline schema. Furthermore, MashQL supports query pipes as a built-in concept, rather than only a visualization of links between modules.

Abstract.
This chapter describes various graphical notations for rule modeling. Rule modeling methodologies, empowered with graphical notations, play an important role in helping business experts and rule engineers to represent business rules formally for further deployment into a rule execution system. Rules, represented graphically, can be easier understood by business people and by technicians without intensive technical learning. In this chapter we mainly focus on three graphical notations for rules: UML/OCL, URML and ORM. UML/OCL is a mainstream modeling technology in software development, which is also accommodated by some business experts when modeling a system at the semi-formal, platform independent level. URML extends UML with additional graphical symbols and the concept of a rule, which allows visualization of different rule types on top of UML class diagrams. ORM is an alternative methodology with a rich graphical notation for modeling a domain at the conceptual level. The methodological power, graphical expressivity, and verbalization capabilities of ORM have made it the most popular language within the business rules community. This chapter introduces each of these graphical notations, explain how it can be used, and compare them against each other.

Abstract. This article is motivated by the importance of building web data mashups. Building on the remarkable success of Web 2.0 mashups, and specially Yahoo Pipes, we generalize the idea of mashups and regard the Internet as a database. Each internet data source is seen as a table, and a mashup is seen as a query on these tables. We assume that web data sources are represented in RDF, and SPARQL is the query language.
We propose a query-by-diagram language called MashQL. The goal is to allow people to build data mashups diagrammatically.
In the background, MashQL queries are translated into and executed as SPARQL queries. The novelty of MashQL is that it allows querying a data source without any prior understanding of the schema or the structure of this source. Users also do not need any knowledge about RDF/SPARQL to get started.

Abstract. This chapter presents
an ontology for customer complaint management, which has been developed
in the CCFORM project. CCFORM is an EU funded project (IST-2001-38248)
with an aim of studying the foundation of a central European customer
complaint portal. The idea is that any consumer can register a complaint
against any party about any problem, at one portal. This portal
should: support 11 languages, be sensitive to cross-border business
regulations, dynamic, and can be extended by companies. To manage
this dynamicity and to control companies' extensions, a customer
complaint ontology (CContology) has to be built to underpin the
CC portal. In other words, the complaint forms are generated based
on the ontology. The CContology comprises classifications of complaint
problems, complaint resolutions, complainant, complaint-recipient,
''best-practices'', rules of complaint, etc. The main uses of this
ontology are 1) to enable consistent implementation (and interoperation)
of all software complaint management mechanisms based on a shared
background vocabulary, which can be used by many stakeholders. 2)
to play the role of a domain ontology that encompasses the core
complaining elements and that can be extended by either individual
or groups of firms; and 3) to generate CC-forms based on its ontological
commitments and to enforce the validity (and/or integrity) of their
population. To end, we outline our experience in applying the methodological
principles (Double-Articulation and Modularization) and the tool
(DogmaModeler) that we used in developing the CContology.

Abstract. Reasoning with ontologies is a challenging task specially for non-logic experts. When checking
whether an ontology contains rules that contradict each other, current description logic reasoners can
only provide a list of the unsatisfiable concepts. Figuring out why these concepts are unsatisfiable,
which rules cause conflicts, and how to resolve these conflicts, is all left to the ontology modeler himself.
The problem becomes even more challenging in case of large or medium size ontologies, because
an unsatisfiable concept may cause many of its neighboring concepts to be unsatisfiable.
The goal of this article is to empower ontology engineering with a user-friendly reasoning mechanism.
We propose a pattern-based reasoning approach, which offers 9 patterns of constraint contradictions
that lead to unsatisfiability in Object-role (ORM) models. The novelty of this approach is not
merely that constraint contradictions are detected, but mainly that it provides the causes and suggestions
to resolve contradictions. The approach is implemented in the DogmaModeler ontology engineering
tool, and tested in building the CCFORM ontology. We discuss that, although this pattern-based
reasoning covers most of contradictions in practice, compared with description logic based reasoning,
it is not complete. We argue and illustrate both approaches, pattern-based and description logic-based,
their implementation in the DogmaModeler, and conclude that both complement each other from a
methodological perspective.

Abstract. The main goal of
this chapter is to present a methodological framework for ontology
engineering (called DOGMA), which is aimed to guide ontology builders
towards building ontologies that are both highly reusable and usable,
easier to build, and smoother to maintain. First, we investigate
the main foundational challenges in ontology engineering. We examine
to what extent one can build an ontology independently of application
requirements at hand. We discuss ontology reusability verses ontology
usability. Second, we present the DOGMA approach, and its philosophy
and formalization, which suggests that an ontology be built as separate
domain axiomatization and application axiomatizations. While a domain
axiomatization focuses on the characterization of the intended meaning
(i.e. intended models) of a vocabulary at the domain level, application
axiomatizations mainly focus on the usability of this vocabulary
according to certain application/usability perspectives. An application
axiomatization is intended to specify the legal models (a subset
of the intended models) of the application(s)’ interest. Furthermore,
we show how specification languages such as (ORM, UML, EER, OWL,
etc.) can be well (re)used in ontology engineering.

Abstract. We map ORM into the
SHOIN/OWL, which is the most common description logic in ontology
engineering. As SHOIN/OWL is known to be a good compromise between
expressiveness and computational complexity, this implies that the
ORM constraints mapped in this paper are the constraints that are
easier to implement and reason about. Our mappings are implemented
as an extension to the DogmaModeler tool, which uses Racer as a
background reasoning engine. Furthermore, the expressive, methodological,
and graphical capabilities of ORM make it a good candidate for use
as a graphical notation for ontology languages. In this way, industrial
experts who are not IT savvy will still be able to build and view
ontologies without needing to know the logic or reasoning foundations
underpinning them.

Abstract. The goal of this
article is to formalize Object Role Modeling (ORM) using the DLR
description logic. This would enable automated reasoning on the
formal properties of ORM diagrams, such as detecting constraint
contradictions and implications. In addition, the expressive, methodological,
and graphical capabilities of ORM make it a good candidate for use
as a graphical notation for most description logic languages. In
this way, industrial experts who are not IT savvy will still be
able to build and view axiomatized theories (such as ontologies,
business rules, etc.) without needing to know the logic or reasoning
foundations underpinning them. Our formalization in this paper is
structured as 29 formalization rules, that map all ORM primitives
and constraints into DLR, and 2 exceptions of complex cases. To
this end, we illustrate the implementation of our formalization
as an extension to DogmaModeler, which automatically maps ORM into
DIG and uses Racer as a background reasoning engine to reason about
ORM diagrams.

Abstract. In this paper, we
first introduce the notion of gloss for ontology engineering
purposes. We propose that each vocabulary in an ontology should
have a gloss. A gloss basically is an informal description of the
meaning of a vocabulary that is supposed to render factual and critical
knowledge to understanding a concept, but that are unreasonable
or very difficult to formalize and/or articulate formally. We present
a set of guidelines on what should and should not be provided in
a gloss. Second, we propose to incorporate linguistic resources
in the ontology engineering process. We clarify the importance of
using lexical resources as a ''consensus reference'' in ontology engineering,
and so enabling the adoption of the glosses found is these resources.
A linguistic resource (i.e. its list of terms and their definitions)
shall be seen as a shared vocabulary space for ontologies. We present
an ontology engineering software tool (called DogmaModeler), and
illustrate its support of reusing of WordNet's terms and glosses
in ontology modeling.

Abstract. We introduce a novel
view on how to deal with the problems of semantic interoperability
in distributed systems. This view is based on the concept of emergent
semantics, which sees both the representation of semantics and the
discovery of the proper interpretation of symbols as the result
of a self-organizing process performed by distributed agents exchanging
symbols and having utilities dependent on the proper interpretation
of the symbols. This is a complex systems perspective on the problem
of dealing with semantics. We highlight some of the distinctive
features of our vision and point out preliminary examples of its
application.

Abstract. ORM (Object-Role
Modeling) is a rich and well-known conceptual modeling method. As
ORM has a formal semantics, reasoning tasks such as satisfiability
checking of an ORM schema naturally arise. Satisfiability checking
allows a developer to automatically detect contradicting constraints.
However, no complete satisfiability checker is known for ORM. In
this paper, we revisit existing patterns from literature that indicate
unsatisfiability of ORM schemes i.e., schemes that cannot be populated,
and we propose refinements as well as additions for them. Although
this does not yield a complete procedure - there may be ORM schemes
passing the pattern checks while containing unsatisfiable roles
- it yields an efficient and easy to implement detection mechanism
(specially in interactive modeling tools) for the most common conceptual
modeling mistakes.

Abstract. We present a novel
approach to support multilingual verbalization of logical theories,
axiomatizations, and other specifications such as business rules.
This engineering solution is demonstrated with the Object Role Modeling
language, although its underlying principles can be reused with
other conceptual models and formal languages, such as Description
Logics, to improve its understandability and usability by the domain
expert. Our engineering solution for multilingual verbalization
is characterized by its flexibility, extensibility and maintainability
of the verbalization templates, which allow for easy augmentation

Abstract. In this paper we present
a framework and algorithm for modularization and composition of
ORM schemes. The main goals of modularity are to enable and increase
reusability, maintainability, distributed development of ORM schemes.
Further, we enable effective browsing and management of such schemes
through libraries of ORM schema modules. For automatic composition
of modules, we present and implement a composition operator: all
atomic concepts and their relationships (i.e. fact-types) and all
constraints, across the composed modules, are combined together
to form one schema (called modular schema).

Abstract. With ''peer production''
becoming commonplace and new standards like RDF or OWL paving the
way for the much anticipated semantic web, a new breed of very large
scale semantic systems is about to appear. Traditional semantic
reconciliation methods, dependent upon shared vocabularies or global
ontologies, cannot be used in such open and dynamic environments.
Instead, new heuristics based on emerging properties and local consensuses
have to be exploited in order to foster semantic interoperability
in the large. In this paper, we outline the main differences between
traditional semantic reconciliation methods and these new heuristics.
Also, we characterize the resulting emergent semantics systems and
provide a couple of hints vis-a-vis their potential applications.

Abstract. This paper tackles
two main disparities between conceptual data schemes and ontologies,
which should be taken into account when (re)using conceptual data
modeling techniques for building ontologies. Firstly, conceptual
schemes are intended to be used during design phases and not at
the run-time of applications, while ontologies are typically used
and accessed at run-time. To handle this first difference, we define
a conceptual markup language (ORM-ML) that allows to represent ORM
conceptual diagrams in an open, textual syntax, so that ORM schemes
can be shared, exchanged, and processed at the run-time of autonomous
applications. Secondly, unlike ontologies that are supposed to hold
application-independent domain knowledge, conceptual schemes were
developed only for the use of an enterprise application(s), i.e.
“in-house” usage. Hence, we present an ontology engineering-framework
that enables reusing conceptual modeling approaches in modeling
and representing ontologies. In this approach we prevent application-specific
knowledge to enter or to be mixed with domain knowledge. To end,
we present DogmaModeler: an ontology-engineering tool that implements
the ideas presented in the paper.

Abstract. This paper presents
an ontology-based approach for managing and maintaining multilingual
online customer complaints. To achieve trust and transparency in
e-commerce communications and transactions, effective and cross-border
complaint platforms need to be established and may be integrated
in e-business activities. The effectiveness and width of such complaint
service platforms depend on rising to several challenges, such as
the sensitivity of business regulations and complaint resolution,
the language and cultural diversity of the cross-border business
parties, the extensibility according to the market needs and standards.
In this paper, we show how such challenges can be addressed and
simplified: first, we propose the construction of an ontology that
captures the core knowledge of the customer complaint domain. Second,
we show how the extensibility of a complaint platform can be simplified
and managed. Finally, we show how a multilingual representation
of this ontology may be constructed.
This paper outlines our main achievements in Topic Panel 6 (“Ontology,
Extensibility and Integration”), which is a special interest
group in the EU CCFORM Thematic Network project.

Abstract. This paper
presents a specifically database-inspired approach (called DOGMA)
for engineering formal ontologies, implemented as shared resources
used to express agreed formal semantics for a real world domain.
Our methodology aims to addresses several related issues, such
as (a) the scalability of building and sharing ontologies; (b)
the maximization of knowledge reusability; (c) the design and
engineering process, that also simplifies building and managing
ontologies; (d) the coexistence of several rule systems and ontology
languages around a same ontology; and (e) the reconcile of the
need to represent semantics independently from language with the
need to create and use processes entirely rooted and described
in (natural) language. We first define formal ontologies in a
logic sense, i.e. as ''representationless'' mathematical objects
that form the range of a classical interpretation mapping from
a first order language (sometimes called a conceptual schema,
and assumed to lexically represent an application), to a set of
possible (''plausible'') conceptualizations of the real world domain.
We then give a database-inspired ''view'' on implementations of
ontologies seen as resources. Following common model-theoretic
database practice we decompose such resources into ontology bases
and into of their explicit so-called ontological commitments.
Such architecture allows to make the latter (crucial) notion explicit
as a separate layer, with concrete and dedicated services, mediating
between the ontology base and the application instances that commit
to the ontology. We claim it also leads to methodological approaches
that naturally extend database modeling theory and practice, and
so may in turn lead to scalable solutions for ontology-based systems.
We discuss examples of the DOGMA implementation of the ontology
base server and commitment server.

Abstract. Unlike data
models, the main fundamental asset of ontologies is the independency
from a particular application's needs, i.e. relatively generic
domain knowledge that can be used and reused among different kinds
of applications. The first main topic of this paper is to discuss
some independency aspects that help to understand the differences
and similarities between ontologies and data models. The second
main topic of this paper is to present an ontology engineering
framework that increases the independency between an ontology
and applications that use it. Our ontology engineering approach
separates ''atomic'' conceptual relations and ''predicative'' domain
rules. An ontology, defined in this way, consists of an ontology
base that holds intuitive context-specific conceptual relations
and a layer of ''relatively generic'' ontological commitments that
hold the ontology rules. The latter may be seen as reusable knowledge
components.

Abstract. The Internet
creates a strong demand for standardized exchange not only of
data itself but especially of data semantics, as this same internet
increasingly becomes the carrier of e-business activity (e.g.
using web services). One way to achieve this is in the form of
communicating ''rich'' conceptual schemas. Conceptual modeling techniques
such as EER, ORM and to some extent the UML have been developed
in the past for building information systems. These techniques
or suitable extensions can often also be used to design business
applications at a conceptual level. In this paper we adopt the
well-known CM technique of ORM, which has a rich complement of
business rule specification, and develop ORM-ML, an XML-based
markup language for ORM. Clearly domain modeling of this kind
will be closely related to work on so-called ontologies and we
will briefly discuss the analogies and differences, introducing
methodological patterns for designing distributed business models.
Since ORM schemas are typically saved as graphical files, we designed
a textual representation as a marked-up document in ORM-ML so
we can save these ORM schemas in a more machine exchangeable way
that suits networked environments. Moreover, we can now write
style sheets to convert such schemas into another syntax, e.g.
pseudo natural language, a given rule engine's language, first
order logic, a given rule engine's language. We give (in appendix)
a complete formal definition (''grammar'') of ORM-ML as an XML Schema,
a comprehensive description of all of ORM's business rules in
ORM-ML syntax and present an algorithm to map ORM schemas into
ORM-ML. We illustrate the concept on a number of examples.

Abstract. The purpose
thesis of this paper is to present and discuss the scalability
and reusability capabilities of DOGMA, an ontology modeling approach.
Ontologies are repositories of domain knowledge and essential
for knowledge management in organizations and for achieving interoperation
among information systems. In the DOGMA ontology server architecture,
we implement ontologies as classical database resources separating
the ''fact base'' from the constraints, rules, derivations etc.
that commit an application to such a given ontology ''base''. This
separation allows an increased degree of scalability and reusability
for the activities of ontology building. These are key issues
in the context of the so-called Semantic Web where very large
numbers of partial ontologies will emerge.

Abstract. This paper
describes a semantic portal through which knowledge can be gathered,
stored, secured and accessed by members of a certain community.
In particular, this portal takes into account companies and research
institutes participating in the E. U. funded thematic network
called OntoWeb. Ontology-based annotation of information is a
prerequisite in order to offer the possibility of knowledge retrieval
and extraction. The usage of well-defined semantics allows for
the knowledge exchange between different OntoWeb community members.
Thus, members are able to publish annotated information on the
web, which is then crawled by a syndicator and stored in the portal's
knowledge base. The backbone of the portal architecture consists
of a knowledge base in which the ontology and the instances are
stored and maintained. In addition, ontology-boosted query mechanisms
and presentation facilities are provided.

Abstract. In this
paper we present the advantages of using an ontology service for
the modelling of user profiles in the EC FP5 IST project NAMIC
(IST-1999-12392). By means of an ontology server people set up
user profiles, which are in fact views, i.e. specifications of
queries on the ontology. These views are constructed using a JAVA
API, which forms the commitment layer of the ontology, built on
top of an ontology base. In NAMIC an ontology server is used to
establish a link between the lexical object representations, generated
by the natural language processors (NLP) on the one hand and the
user's interest, specified through the selection of relevant concepts
and facts of the ontology on the other. This allows to specify
a user profile independently of language, categorization and NLP
specific world models. Users then set up a profile consisting
of events, agents participating in these events and other content
information in which they are interested in. For instance, a journalist
writing articles about financial issues may be interested in related
documents containing a ''raise event'' of company shares. If he
has specified those conditions in his profile he will be able
to retrieve resources which contain events that are semantically
related to that kind of event pattern. User profiles in NAMIC
do not have to be static. The results of processing by the NLPs
of a document the user is currently working on, may be used to
construct a dynamic profile, which may contain events specific
for that document. This way a user's profile can be dynamically
adapted to his current interests. We also developed a tool which
illustrates the creation of user profiles using ontological concepts
and facts.
