In this paper, we propose a single lowdimensional
representation of a large collection
of table and hyponym data, and show
that with a small number of primitive operations,
this representation can be used effectively
for many purposes. Specifically we consider
queries like set expansion, class predi ...

Traditionally, Information Extraction (IE) has focused
on satisfying precise, narrow, pre-specified
requests from small homogeneous corpora (e.g.,
extract the location and time of seminars from a
set of announcements). Shifting to a new domain
requires the user to name the target relations and
to ma ...

Dynamic content is a frequently accessed part
of the Web. However, most information extraction
approaches are batch-oriented, thus
not effective for gathering rapidly changing
data. This paper proposes a model for fact
extraction in real-time. Our model addresses
the difficult challenges that timely ...

Knowledge bases (KB) provide support for
real-world decision making by exposing data
in a structured format. However, constructing
knowledge bases requires gathering data from
many heterogeneous sources. Manual efforts
for this task are accurate, but lack scalability,
and automated approaches provid ...
