Department of Computer Science Activity 1998-2004
This report summarizes much of the research and teaching activity of the Department of Computer Science at Dartmouth College between late 1998 and late 2004. The material for this report was collected as part of the final report for NSF Institutional Infrastructure award EIA-9802068, which funded equipment and technical staff during that six-year period. This equipment and staff supported essentially all of the department\u27s research activity during that period
CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap
After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in
multimedia search engines, we have identified and analyzed gaps within European research effort during our second year.
In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio-
economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown
of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on
requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the
community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our
Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as
National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core
technological gaps that involve research challenges, and βenablersβ, which are not necessarily technical research
challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal
challenges
Expanding Data Imaginaries in Urban Planning:Foregrounding lived experience and community voices in studies of cities with participatory and digital visual methods
βExpanding Data Imaginaries in Urban Planningβ synthesizes more than three years of industrial research conducted within Gehl and the TechnoβAnthropology Lab at Aalborg University. Through practical experiments with social media images, digital photovoice, and participatory mapmaking, the project explores how visual materials created by citizens can be used within a digital and participatory methodology to reconfigure the empirical ground of data-driven urbanism. Drawing on a data feminist framework, the project uses visual research to elevate community voices and situate urban issues in lived experiences. As a Science and Technology Studies project, the PhD also utilizes its industrial position as an opportunity to study Gehlβs practices up close, unpacking collectively held narratives and visions that form a particular βdata imaginaryβ and contribute to the production and perpetuation of the role of data in urban planning. The dissertation identifies seven epistemological commitments that shape the data imaginary at Gehl and act as discursive closures within their practice. To illustrate how planners might expand on these, the dissertation uses its own data experiments as speculative demonstrations of how to make alternative modes of knowing cities possible through participatory and digital visual methods
Hybrid approaches based on computational intelligence and semantic web for distributed situation and context awareness
2011 - 2012The research work focuses on Situation Awareness and Context Awareness topics.
Specifically, Situation Awareness involves being aware of what is happening in the vicinity
to understand how information, events, and oneβs own actions will impact goals and objectives,
both immediately and in the near future. Thus, Situation Awareness is especially
important in application domains where the information flow can be quite high and poor
decisions making may lead to serious consequences.
On the other hand Context Awareness is considered a process to support user applications
to adapt interfaces, tailor the set of application-relevant data, increase the precision of
information retrieval, discover services, make the user interaction implicit, or build smart
environments.
Despite being slightly different, Situation and Context Awareness involve common
problems such as: the lack of a support for the acquisition and aggregation of dynamic environmental
information from the field (i.e. sensors, cameras, etc.); the lack of formal approaches
to knowledge representation (i.e. contexts, concepts, relations, situations, etc.)
and processing (reasoning, classification, retrieval, discovery, etc.); the lack of automated
and distributed systems, with considerable computing power, to support the reasoning on a
huge quantity of knowledge, extracted by sensor data.
So, the thesis researches new approaches for distributed Context and Situation Awareness
and proposes to apply them in order to achieve some related research objectives such
as knowledge representation, semantic reasoning, pattern recognition and information retrieval.
The research work starts from the study and analysis of state of art in terms of
techniques, technologies, tools and systems to support Context/Situation Awareness. The
main aim is to develop a new contribution in this field by integrating techniques deriving
from the fields of Semantic Web, Soft Computing and Computational Intelligence. From
an architectural point of view, several frameworks are going to be defined according to the
multi-agent paradigm.
Furthermore, some preliminary experimental results have been obtained in some application
domains such as Airport Security, Traffic Management, Smart Grids and
Healthcare.
Finally, future challenges is going to the following directions: Semantic Modeling of
Fuzzy Control, Temporal Issues, Automatically Ontology Elicitation, Extension to other
Application Domains and More Experiments. [edited by author]XI n.s

The work of criminal police in modern society is characterized by the proliferation of data
and information to be processed, greater demands for restrictions on personal data, increased public
monitoring, and higher expectations in the efficiency of detecting perpetrators, but still lack
resources, both human and material. One of the more complex tasks is to resolve the identity, the
change of which seeks to cover up criminal activities, i.e., the perpetrator himself, who is on the run.
In order to resolve the identity, it is necessary to group and present all available evidence
related to specific persons. The thesis proposes a clustering approach by comparing pairs of face
feature vectors extracted from images created in unconstrained conditions and based on reasoning
using non-axiomatic logic and graphs. Face clusters will be the central points around which data
from various police reports will be grouped. A system model has also been proposed in which
software agents will play a significant role, primarily in connecting the distribution environment
points formed in practice by police information systems.
The clustering approach was experimentally tested with six different face image databases
characterized by the fact that they were created in a way that simulates unconstrained conditions.
The obtained results of the proposed solution are compared with other state-of-the-art methods. The
results showed that the approach gives similar but mostly better results than the others. What gives a
notable advantage over other methods is the possibility of using mechanisms from non-axiomatic
logic such as revision and deduction, which can be used to acquire new knowledge based on
information from different system nodes, or in the local knowledge base, respectively.Π Π°Π΄ ΠΊΡΠΈΠΌΠΈΠ½Π°Π»ΠΈΡΡΠΈΡΠΊΠ΅ ΠΏΠΎΠ»ΠΈΡΠΈΡΠ΅ Ρ ΡΠ°Π²ΡΠ΅ΠΌΠ΅Π½ΠΎΠΌ Π΄ΡΡΡΡΠ²Ρ ΠΎΠ΄Π»ΠΈΠΊΡΡΠ΅ ΠΏΡΠΎΠ»ΠΈΡΠ΅ΡΠ°ΡΠΈΡΠ°
