Evolutionary Subject Tagging in the Humanities; Supporting Discovery and Examination in Digital Cultural Landscapes
In this paper, the authors attempt to identify problematic issues for subject tagging in the humanities, particularly those associated with information objects in digital formats. In the third major section, the authors identify a number of assumptions that lie behind the current practice of subject classification that we think should be challenged. We move then to propose features of classification systems that could increase their effectiveness. These emerged as recurrent themes in many of the conversations with scholars, consultants, and colleagues. Finally, we suggest next steps that we believe will help scholars and librarians develop better subject classification systems to support research in the humanities.NEH Office of Digital Humanities: Digital Humanities Start-Up Grant (HD-51166-10
A new model to support the personalised management of a quality e-commerce service
The paper presents an aiding model to support the management of a high quality e-commerce service. The approach focuses on the service quality aspects related to customer relationship management (CRM). Knowing the individual characteristics of a customer, it is possible to supply a personalised and high quality service. A segmentation model, based on the "relationship evolution" between users and Web site, is developed. The method permits the provision of a specific service management for each user segment. Finally, some preliminary experimental results for a sport-clothing industry application are described
Towards a Cloud-Based Service for Maintaining and Analyzing Data About Scientific Events
We propose the new cloud-based service OpenResearch for managing and
analyzing data about scientific events such as conferences and workshops in a
persistent and reliable way. This includes data about scientific articles,
participants, acceptance rates, submission numbers, impact values as well as
organizational details such as program committees, chairs, fees and sponsors.
OpenResearch is a centralized repository for scientific events and supports
researchers in collecting, organizing, sharing and disseminating information
about scientific events in a structured way. An additional feature currently
under development is the possibility to archive web pages along with the
extracted semantic data in order to lift the burden of maintaining new and old
conference web sites from public research institutions. However, the main
advantage is that this cloud-based repository enables a comprehensive analysis
of conference data. Based on extracted semantic data, it is possible to
determine quality estimations, scientific communities, research trends as well
the development of acceptance rates, fees, and number of participants in a
continuous way complemented by projections into the future. Furthermore, data
about research articles can be systematically explored using a content-based
analysis as well as citation linkage. All data maintained in this
crowd-sourcing platform is made freely available through an open SPARQL
endpoint, which allows for analytical queries in a flexible and user-defined
way.Comment: A completed version of this paper had been accepted in SAVE-SD

Binary Particle Swarm Optimization based Biclustering of Web usage Data
Web mining is the nontrivial process to discover valid, novel, potentially
useful knowledge from web data using the data mining techniques or methods. It
may give information that is useful for improving the services offered by web
portals and information access and retrieval tools. With the rapid development
of biclustering, more researchers have applied the biclustering technique to
different fields in recent years. When biclustering approach is applied to the
web usage data it automatically captures the hidden browsing patterns from it
in the form of biclusters. In this work, swarm intelligent technique is
combined with biclustering approach to propose an algorithm called Binary
Particle Swarm Optimization (BPSO) based Biclustering for Web Usage Data. The
main objective of this algorithm is to retrieve the global optimal bicluster
from the web usage data. These biclusters contain relationships between web
users and web pages which are useful for the E-Commerce applications like web
advertising and marketing. Experiments are conducted on real dataset to prove
the efficiency of the proposed algorithms
Evoplex: A platform for agent-based modeling on networks
Agent-based modeling and network science have been used extensively to
advance our understanding of emergent collective behavior in systems that are
composed of a large number of simple interacting individuals or agents. With
the increasing availability of high computational power in affordable personal
computers, dedicated efforts to develop multi-threaded, scalable and
easy-to-use software for agent-based simulations are needed more than ever.
Evoplex meets this need by providing a fast, robust and extensible platform for
developing agent-based models and multi-agent systems on networks. Each agent
is represented as a node and interacts with its neighbors, as defined by the
network structure. Evoplex is ideal for modeling complex systems, for example
in evolutionary game theory and computational social science. In Evoplex, the
models are not coupled to the execution parameters or the visualization tools,
and there is a user-friendly graphical interface which makes it easy for all
users, ranging from newcomers to experienced, to create, analyze, replicate and
reproduce the experiments.Comment: 6 pages, 5 figures; accepted for publication in SoftwareX [software
