K. Selcuk Candan is an associate professor at the
School of Computing
and Informatics (Department of Computer Science and
Engineering) at the Arizona State University. He joined the
department in August 1997, after receiving his Ph.D. from
the Computer Science Department at the University of
Maryland at College Park. currently, he is serving as an
associate director for the Arts, Media, and Engineering (AME)
program at ASU and as a founding member for the
Center for
the Cognitive Ubiquitous Computing. Since 1997, he has also been serving
as a visiting research scientist at the
NEC Laboratories,
America.
Prof.
Candan's
primary research interest is
in the area of management of non-traditional, heterogeneous,
and imprecise (such as multimedia, web, and scientific)
data. His various research projects in this domain are funded by
a diverse set of sources, including the National Science Foundation, Department of Defense, and
DES/RSA (Rehabilitation Services Administration). He has
published over 100 articles and many book chapters. He has also
authored 9 patents. Currently, he is co-authoring a book on multimedia databases for the
Cambridge University Press.
Prof. Candan is an editorial board member of one of the
most respected database journals, the Very
Large Databases (VLDB) journal. He is also in the editorial
board of the ACM Digital
Symposium Collection (DiSC) and a steering committee member
for the ACM Multimedia Information Retrieval
(MIR) workshop. He
has also served in the organization and program committees of
various conferences. In 2006, he served as an organization
committee member for SIGMOD'06,
the flagship database conference of the ACM and one of the
best conferences in the area of management of data. In 2008, he
will serve as a PC Chair for another leading, flagship conference of
the ACM, this time focusing on multimedia research (SIGMM'08). He is also a founding organizing committee member of
the First International Conference on Ambient Media and
Systems (Ambi-sys'08), a new conference focusing on the
challenges associated with ubiquitous multimedia.

Ongoing funded research projects
OASIS / iCare-Assistant
DES/RSA Award, Ubiquitous Environment to Facilitate
Access to Textbooks and Related Materials for Adults and
School Age children who are Blind or Visually Impaired,
2006-2010;
NSF ITR Medium Award, iLearn:
IT-enabled Ubiquitous Access to Educational
Opportunities for Blind Individuals, 2003-2008
Principal motivation of
the OASIS project
is to develop novel technologies to improve access to
digital educational content by individuals who are blind or visually impaired.
OASIS is a fully accessible digital library to support students who are blind or
visually impaired.
OASIS provides semi-automated, interactive content registration tools for helping the content providers in uploading
diverse forms of educational materials to OASIS servers. In particular, the content being registered is analyzed and adapted for effective search and navigation support by individuals who are blind.
OASIS servers store the digital library content as well as personal preferences, profiles, and bookmarks of the users. OASIS content access interfaces provide integrated, personalized, and contextualized access to library collections, personal collections user annotations, and bookmarks. In particular, OASIS supports both
browsing/reading (linear, less guidance) as well as focused search (learning, context, more guidance) access mechanisms.
QUEST/FICSR
NSF
Award,
AOC: Archaeological Data
Integration for the Study of Long-Term Human and
Social Dynamics, 2007-2009
Mellon Foundation Award; Digital Antiquity: Planning a Digital Information Infrastructure for Archaeology,
2007-2008
Large-scale archaeological
data are never collected by a single research team, but
must be compiled from many independent projects. QUEST (QUery-driven
Exploration of Semistructured data and metadata with
conflicTs and partial knowledge) is part of a joint
effort of archaeologists and computer scientists to
develop a framework
of collaborative tools that will enable a shared
information infrastructure for archaeology. The meaning
of an archaeological observation is rarely
self-evident. Researchers reach conflicting conclusions,
not just
because their primary data differ, but because they
operationalize
interpretive concepts differently. Thus it is necessary
to maintain the semantic content of original
observations while allowing the extraction of the
maximum meaning possible from existing datasets. Based
on these observations, we are developing a QUEST data model and
system that supports exploratory research on the
incomplete and conflicting data and taxonomies, based on
the query driven data integration and exploration
paradigm. QUEST relies on a novel FICSR query processor
for feedback-driven inconsistency resolution and
reasoning on misaligned data sources
AURA: Design of Dense RFID Systems for Indexing in the Physical World across Space, Time, and Human Experience
ASU-CEINT
Award, Indexing in the Physical World across Space, Time, and Human Experience via dense RFID systems,
2007-2008
NSF (Recommended for funding by the Program Director), Design of Dense RFID Systems for Indexing in the Physical World across Space,
Time, and Human Experience, 2007-2009
Today, individuals have to function in complex environments, with increasing demands on their time and attention. The tasks in the physical world commonly make use of information centric processes, such as search and explore of physical objects.
We envision an informational environment that supports such searches in the physical world. This environment must be transparently embedded with relevant information and should be accessible from small form-factor devices, such as PDAs and cell-phones. In other words, this environment needs to be non-obtrusive and should be organically integrated to individuals’ daily experiences.
RFID technology is a natural platform for addressing the issue of information embeddedness.
Indexing in the physical world across space and time using passive and limited-capability tags require innovative data management research at multiple levels. The cost of random access to a large data structure from a single tag necessitate research onto efficient associative encoding of symbolic and numeric logical search attributes (e.g., color, time, popularity). We also do research into enabling distributed data structures that can resolve queries for remote objects, by accessing only local tags, within the specified radio range. In particular, we introduce the concept of aura which encodes object-memory into the environment. Interrogator-mediated aura propagation techniques, in conjunction with spatio-temporal metadata embedded in the RFID tags,
are exploited for locating matching objects through a
chaining process. Furthermore, in order tackle the issue
of unreliable reads and writes, we introduce efficient, yet effective redundancy mechanisms in aura management.
ARIA
NSF
Award, Quality-Adaptive Media-Flow Architectures to
Support Sensor Data Management, 2003-2007
The objective of our NSF supported data stream research
is to incorporate real-time and archived media and audience
responses into live performances, on-demand. This requires an
innovative information architecture that will process, filter, and
fuse sensory inputs and actuate audio-visual responses in real-time
while providing Quality of Service (QoS) guarantees. We are
developing an adaptive and programmable media-flow ARchitecture for
Interactive Arts (ARIA) that will enable design, simulation, and
execution of interactive performances. ARIA provides a language
interface for specifying intended mappings of the sensory inputs to
audio-visual responses. Based on these specifications, different
inputs are gathered from performers as well as from the audience. They
are then streamed, fused and mapped to different outputs, while
maintaining end-to-end delay requirements as well as providing
response-quality guarantees. Through a fully integrated multimedia
interface, ARIA also brings in external data from databases into live
performances. This research is supported by NSF-IDM Program.

I
enjoy taking pictures...
Okay,
I am not very good, but hey why should that stop me from making
some of them available online? |
