Event schema induction is the task of learning high-level representations of complex events (eg, a bombing) and their entity roles (eg, perpetrator and victim) from unlabeled text. Event …
We explore a semi-supervised approach for improving the portability of time expression recognition to non-newswire domains: we generate additional training examples by …
In this paper we present the design, implementation and evaluation of SOBA, a system for ontology-based information extraction from heterogeneous data resources, including plain …
With the rapid growth of online information services, a sheer volume of news data becomes available. To help people quickly digest the explosive information, we define a new problem …

Automatic event schema induction (AESI) means to extract meta-event from raw text, in other words, to find out what types (templates) of event may exist in the raw text and what roles …
With the increasing amount of data and the exploding number data sources, the extraction of information about events, whether from the perspective of acquiring knowledge or from a …
