This can be of great help for small and medium enterprises (SMEs), =
as an=20
effective way to share information. However, it can be difficult =
for SMEs=20
to have access to a fully integrated CWE providing different tools =
(e.g.,=20
videoconferencing, instant messaging, etc.). Currently, they may =
define a=20
CWE as a combination of heterogeneous and non-integrated tools =

provide SMEs with the necessary means to collaborate, making =

Devolved Ontology in Practice for a Seamless Semantic Alignment =

Dynamic Collaboration Networks of SMEs C.A. Marin, M. =
Carpenter, U.=20
Wajid, N. Mehandjiev
The lack =
of a=20
semantic alignment between collaborating small and medium =
enterprises=20
causes frequent misinterpretations when exchanging information in =
the form=20
of documents. If these companies are to achieve a seamless =
semantic=20
alignment by exchanging documents, we should employ a conceptual =
model=20
which does not rely on agreeing in advance on a centralised =
standard for=20
document contents and format, but instead allows individual =
companies to=20
maintain localised ontologies structuring their own documents =
allowing the=20
companies to automatically establish a semantic alignment between =
pairs of=20
collaborating companies, taking into account the ripple effects =
that such=20
an alignment could trigger. In this article we demonstrate how the =
conceptual model of devolved ontology is engineered and tested to =
support=20
such a scenario: we show how we have engineered the devolved =
ontology=20
through a case study, and present experimental results on the =
document=20
alignment intrinsically needed for this.

one key factor to remain competitive. The required flexibility in =
people=20
driven processes is usually achieved through ad-hoc workflows =
which are=20
naturally highly unstructured. Effective guidance in ad-hoc =
workflows=20
therefore requires a simultaneous consideration of multiple goals: =

on the=20

tools
Enterprise 2.0 has been introduced in the SME =
(Small=20
Medium Enterprise) modifying common organizational and operative=20
practices. This brings the `knowledge workers' to change their =
working=20
practices through the use of web 2.0 communication tools. =
Unfortunately,=20
these tools do not allow intercepting and tracing the exchanged =
data,=20
which can produce a loss of information. This is an important =
problem in=20
an enterprise context because knowledge of the exchanged =
information can=20
increase the efficiency and competitiveness of the company. In =
this=20
article we demonstrate that it is possible to extract this =
knowledge by an=20

Combining Web 2.0 and Web Services in Collaborative Working=20

Web services, web 2.0, CSCW, interoperability,=20
distributed systems and information =
systems
Collaborative=20
applications offer significant benefits in business sector. =
Usually, team=20
members need to use several systems to carry out their tasks. What =
these=20
users need is an environment which permits them to carry out these =
tasks=20
automatically, considering the flow of information between the =
different=20
systems and offering interoperability and composition features. =
Nowadays,=20
Web Services have gained their prominence in providing these both=20
features. On the other hand, the use of Web 2.0 allows to create =
web=20
applications in which the user constitutes a key element. What we =
propose=20
in this paper is the combination of both approaches for creating a =
Collaborative Working Environment (CWE).
Folksonomy and tagging systems, which allow users to interactively =
annotate a pool of shared resources using descriptive tags, have =
enjoyed=20
phenomenal success in recent years. The concepts are organized as =
a map in=20
human mind, however, the tags in folksonomy, which reflect users'=20
collaborative cognition on information, are isolated with current=20
approach. What we do in this paper is to estimate the semantic =
relatedness=20
among tags in folksonomy: whether tags are related from semantic =
view,=20
rather than isolated? We introduce different algorithms to form =
networks=20
of folksonomy, connecting tags by users collaborative tagging, or =
by=20
resource context. Then we perform multiple measures of semantic=20
relatedness on folksonomy networks to investigate semantic =
information=20
within them. The result shows that the connections between tags =
have=20
relatively strong semantic relatedness, and the relatedness =
decreases=20
dramatically as the distance between tags increases. What we find =
in this=20
paper could provide useful visions in designing future =
folksonomy-based=20
systems, constructing semantic web in current state of the =
Internet, and=20

Leukocyte =

of the essential steps in an automatic leukocyte recognition =
system. Due=20
to the complexity of the overlapping cell images, methods for =
leukocyte=20
segmentation are still needed. In this paper, we first construct a =
combined image by saturation and green channels to extract the =
nucleus and=20
in turn locate a cursory circular region of the leukocyte. Then =
the=20

We=20
