Brief Bio of Dr Moira C. Norrie
Moira C. Norrie is a Professor of Computer Science at
ETH Zurich where she leads the Global Information Systems (GlobIS)
research group. She studied in her home country of Scotland, obtaining a
BSc in Mathematics from the University of Dundee, an MSc in Computer
Science from Heriot-Watt University and a PhD in Computer Science from
the University of Glasgow.
Moira’s research and teaching focuses on the use of object-oriented and
web technologies for next generation information systems. In the early
1990s, she developed the OM model of data which supports an extended
entity-relationship approach to data management in object-oriented
systems. Since then a number of OMS systems and frameworks have been
developed within her group based on the OM model. The latest is OMS Avon
which is a semantic data management layer for db4o. A common goal of
many research projects is to investigate how object databases can be
empowered to support novel forms of interaction and information sharing.
The OMS systems have been used as implementation platforms for numerous
projects within the GlobIS group. These include the development of
iPaper which is a general framework for the prototyping and production
of interactive paper documents and paper-based interfaces to
applications.
Abstract:
Emerging technologies for interactive paper make it
possible to capture and access information from paper in a variety of
interesting ways. Over the past seven years, we have developed a rich
infrastructure for the prototyping and production of interactive paper
documents and paper-based interfaces to applications. We will provide a
review of this work, starting with a motivation for reforming rather
than replacing paper and then going on to describe various ways in which
paper can be linked to information systems to support both the capture
of and access to information. This will include an introduction to
commercial digital pen and paper technologies that can be used to
capture user actions on paper as well as our own iPaper framework and
associated publishing tools.

been visiting professor or invited speaker at several conferences and
universities all around the world, as well as referee of several
journals, conferences, NSF, etc. He is member of the ACM, EATCS, IEEE,
SCCC and SIAM.
Abstract:
Distributed search engines are often more complex to
implement compared to centralized engines. Distributing a search engine
across multiple sites, however, has several advantages. In particular,
it enables the utilization of less computer resources and the
exploitation of data and user locality. In this presentation we show the
feasibility of distributed Web search engines, by proposing a model for
assessing the total cost of a distributed Web-search engine that
includes the computational costs as well as the communication cost among
all distributed sites.
Using examples, we show that a distributed Web search engine can be more
cost effective than a centralized one, if there is a large percentage of
local queries, which is usually the case.
We then present a query-processing algorithm that maximizes the amount
of queries answered locally, without sacrificing the quality of the
results, by using caching and partial replication.
We simulate our algorithm on real document collections and real query
workloads to measure the actual parameters needed for our cost model,
and we show that a distributed search engine can be competitive compared
to a centralized architecture with respect to cost. This is joint work
with Aris Gionis, Flavio Junqueira, Vassilis Plachouras and Luca
Telloli.

Abstract:
Traditionally, business value networks have
orchestrated human and technical resources that worked together to form
relationships and to add value to a product or service. The Internet and
the Web have extended traditional business networks by allowing also a
web of different digital resources to work together to create value.
Additionally, the increasing adoption of service-oriented architectures
has allowed the creation of service ecosystems in which Web services are
exposed and connected. The TEXO project proposes to combine these two
trends to create what is called Future Business Value Networks which
enable IT-supported value networks via service ecosystems. This paper
addresses the main challenging issues that need to be explored to
provide an integrated technical infrastructure to support this emerging
new type of business networks.

Abstract:
Information Systems can be traced back to prehistory,
although at that time the way information was recorded and transmitted
was obviously rudimentary. The “invention” of writing marks the move
from Pre-history to History. It played a fundamental role in the
apparition of complex societies and corresponding Information Systems.
In fact, the story of Information Technology is actually closely linked
to the History of Writing, the History of Computing and the History of
Informatics. The notion of information is obviously central to
all these fields, but what is interesting and sometimes forgotten is
that no information can be shared without some agreement on some kind of
language.
The notion of language is key, both for mankind and for Informatics. In
this presentation we give a short presentation of languages, starting
from natural languages, to languages for special purposes, languages for
sciences and techniques, computer languages and finally what we coin as
Software Languages, namely languages used to develop the
Software. This includes ontologies, schemas, grammars, metamodels, and
many kinds of proto-languages taking different forms. We argue that the
notion of Software Language is a cornerstone of modern Information
Systems. For the first time in the history of mankind implicit and
informal descriptions of languages are no longer suitable to
information-processing needs. Automatic processing will be possible only
if the description of software languages is made explicit. We argue that
this requirement should be considered both from a scientific and
an engineering perspective, leading respectively to the emerging fields
of Software Linguistics and Software Language Engineering.
