The main research projects are:
- Metasearch engine utilizes
numerous search engines to search the Web and integrates the results to serve the users.
- Retrieval of pictures
based on approximate contents. This has wide applications in entertainment, education, law enforcement and military
- Automatic analysis of unstructured
(in natural language)
product surveys can be analyzed and concisely described without examining individual documents.
- Relationships between names of attributes/entities. Relationships are in the form of synonyms, homonyms, is-a relationships and
aggregate relationships. This information is useful in schema integration.
- Data mining, text and Web mining. This
research seeks to develop new methods of extracting underlying patterns from data, text and Web pages, and/or building
in database environment. This is important when the amount of data is huge, there is large number of users and
stringent time requirements are imposed.
- Active databases.
These types of databases have immense applications in computer systems, traffic management systems, security trading
and communication networks.
- Data replication in mobile computing.
Minimize charges by using appropriate data replication schemes.
- Fuzzy relational systems.
This allows imprecise queries to be answered in the presence of imprecise data.
- Visualization and integration of heterogeneous information. Applications include geospatial databases containing XML and multimedia information.
- Moving objects databases. Research
issues include modeling of dynamic location information, uncertainty management, spatio-temporal data access languages,
indexing and scalability issues, data mining (including traffic and location prediction), location dissemination,
privacy and security, location fusion and synchronization.
