WISDM: Web Indexing and Search for Dynamic Mining
The immense scale and wide spread has rendered the Web as an
ultimate information repository-- as not only the sources where we
find but also the destinations where we publish our
information. These dual forces have enriched the Web with all
kinds of data, much beyond the conventional page
view of the Web as a corpus of HTML pages, or "documents".
Consequently, the Web is now a rich collection of data-rich
pages, on the "surface Web" of static URLs (e.g, personal or
company homepages) as well as the "deep Web" of database-backed
contents (e.g, flights from aa.com). The richness of data, while a
promising opportunity, has challenged us for effectively finding
data we need. We propose to build novel search systems, to faciliate users' quest of data on the Web.
Projects
-
Entity Search: to propose and build a novel Web Search Engine beyond
document retrieval, that searches upon Entities,
for instance, email, phone number, address, etc.
-
Entity Extraction: to study general, scalable, and robust extraction frameworks that support various types of entity extraction tasks.
-
Relational Mining on the Web: to achieve entity relational mining, the next step after entity search results.
-
Object Search: to propose and build a search system that searches upon web objects represented in documents.
