1. Time Travel with Main-Memory Database
Prof. Sang Kyun Cha (Seoul National University, SAP R&D Center Korea)
(TBA)
2. Keyword Search in Databases: The Power of RDBMS
Prof. Jeffrey Xu Yu (Chinese University of Hong Kong, China)
Abstract: Keyword search in relational databases (RDBs) has been
extensively studied recently. A keyword search (or a keyword query)
in RDBs is specified by a set of keywords to explore the
interconnected tuple structures in an RDB that cannot be easily
identified using SQL on RDBMSs. In brief, it finds how the tuples
containing the given keywords are connected via sequences of
connections (foreign key references) among tuples in an RDB. Such
interconnected tuple structures can be found as connected trees up
to a certain size, sets of tuples that are reachable from a root
tuple within a radius, or even multi-center subgraphs within a
radius. In the literature, there are two main approaches. One is to
generate a set of relational algebra expressions and evaluate every
such expression using SQL on an RDBMS directly or in a middleware on
top of an RDBMS indirectly. Due to a large number of relational
algebra expressions needed to process, most of the existing works
take a middleware approach without fully utilizing RDBMSs. The other
is to materialize an RDB as a graph and find the interconnected
tuple structures using graph-based algorithms in memory. In this
talk we focus on using SQL to compute all the interconnected tuple
structures for a given keyword query. We show that the current
commercial RDBMSs are powerful enough to support such keyword
queries in RDBs efficiently without any additional new indexing to
be built and maintained.
3. Spatiotemporal Query Processing: What's New and What's Hot
Prof. Xiaofang Zhou (University of Queensland, Australia)
Abstract: Spatiotemporal query processing becomes an active
research area again in recent years, driven by not only
intellectually challenging research issues related to performance,
scalability and uncertainty emerging from many new applications, but
also the wide spread adoption of positioning devices, location-based
services and high quality digital maps. In this talk, we will
present an overview of this research field, followed by discussions
of our recent work in motion pattern discovery, pattern-based
movement predication (ICDE'08), convey detection (VLDB'08) and
path-based nearest neighbor monitoring (SIGMOD'09). The aim of this
talk is to share with the researchers in this area our new results,
and also to provide an introduction for those who are new to this
area.
4. Build Intelligence from the Physical World
Dr. Xing Xie (Microsoft Research Asia, China)
Abstract: Context aware computing sought to deal with linking
changes in the environment with computer systems. In other words,
computing systems become more intelligent through analyzing and
reacting to the physical world surrounding them. The coming era of
cloud computing brings new opportunities to this long studied
research area. By accumulating and aggregating physical world
contextual information from multiple users and multiple devices over
a long period, we can obtain collective social intelligence from
them. Based on this, more innovative Internet services can be
developed to facilitate people's everyday lives. At Microsoft
Research Asia, we are working on various technologies with a view to
managing physical world information and building intelligence from
them. In this talk, I will present our recent work on this
direction, as well as other related works in Microsoft and the
industry.
5. Geographic Information Retrieval: Algorithms and Approaches
Prof. Ray Larson (University of California at Berkeley, USA)
Abstract: The goal of Geographic Information Retrieval (GIR) is to
retrieve relevant information resources in response to queries with
geographic constraints. GIR implies that the indexing and retrieval
of objects in a digital collection takes into account some form of
georeferencing, and may use various forms of geographical proximity,
containment, or other spatial relations in estimating or predicting
geographic relevance. Systems that provide searches using GIR
methods, including geographic digital libraries, and location-aware
web search engines, are based on a collection of georeferenced
information resources and methods to spatially search these
resources with geographic location as part of their search
specifications. Information resources in digital library collections
can be considered georeferenced if they are spatially indexed by one
or more regions or points on the surface of the Earth, where the
specific locations of these regions are encoded using spatial
coordinates directly (geometrically), or indirectly by toponyms
(place names). In this lecture we will examine the effectiveness of
Geographic Information Retrieval (GIR) methods in IR systems. We
will show how various types of information may benefit from explicit
geographic search, and where text-based place name search may be
sufficient. We will also show how implicit geographic search (or
geographic browsing) can be used to dynamically generate geographic
searches in geographic interfaces like Google Earth. We will
describe the algorithms used for Geographic search and how these may
be combined with topical text searches. In addition we will show
results from the GeoCLEF IR evaluation for text-based geographic
search.
6. Information Access Evaluation: Some Recent Topics
Dr. Tetsuya Sakai (Microsoft Research Asia, China)
Abstract: This talk will briefly touch upon various aspects of
information access evaluation, including: - New information
retrieval metrics; - New problems in information access evaluation,
e.g. incompleteness of relevance assessments; - How to evaluate
evaluation metrics and test collections; - New information access
tasks, e.g., IR4QA at NTCIR, exploratory search etc.; - The gap
between laboratory experiments and the real world; - The gap between
academia and industry.
