distributed search over text databases, desktop search, information
extraction, text mining.
Some Past and Current Research Projects
- SQOUT, a system for
structured querying of text databases, via information extraction (ICDE '09 paper, SIGMOD Record '08 paper, ICDE '08 paper, TODS '07 paper, SIGMOD '06 paper)
- QProber, a system
for automatically classifying and searching "hidden-web" text databases
(TOIS '08 paper, TODS '07 paper, ICDE '05 paper, SIGMOD '04 paper, TOIS '03 paper, VLDB '02 paper, March '02 IEEE Data Engineering Bulletin
paper)
- RANK: Top-k query
processing (over relational databases: TODS '02 paper; over web-accessible
databases: TODS '04 paper; over
multimedia databases: TKDE '04 paper)
- Snowball and QXtract,
building
blocks
for
efficient information extraction (ICDE
'03
paper [errata], WebDB '03 paper, DL
'00 paper)
- SDARTS, a protocol
and toolkit for metasearching (JCDL
'02 paper, JCDL
'01
paper)
- GeoSearch, a
geographically-aware search engine (CIKM
