“…Finally, detection and resolution of implicit arguments is an instance of zero anaphora detection and resolution (Silberer and Anette, 2012, Tetreault 2002, Whittemore et al, 1991, Palmer et al, 1986. We present an empirical approach for understanding these phenomena in instructions.…”

We present an unsupervised hard EM approach to automatically mapping instructional recipes to action graphs, which define what actions should be performed on which objects and in what order. Recovering such structures can be challenging, due to unique properties of procedural language where, for example, verbal arguments are commonly elided when they can be inferred from context and disambiguation often requires world knowledge. Our probabilistic model incorporates aspects of procedural semantics and world knowledge, such as likely locations and selectional preferences for different actions. Experiments with cooking recipes demonstrate the ability to recover high quality action graphs, outperforming a strong sequential baseline by 8 points in F1, while also discovering general-purpose knowledge about cooking.

“…The constraints above are similar to those used in the FASTUS IE system (Appelt et al, 1995) and by Sown (1984), where the merging takes place between template structures, considering special conditions for the unification of variables in template slots. However, the general approach here has more in common with Whittemore and Macpherson (1991) or Zarri (1992), where event merging is carried out within the underlying knowledge representation.…”

We propose a general approach for performing event coreference and for constructing complex event representations, such as those required for information extraction tasks. Our approach is based on a representation which allows a tight coupling between world or conceptual modelling and discourse modelling. The representation and the coreference mechanism are fully implemented within the LaSIE information extraction system where the mechanism is used for both object (noun phrase) and event coreference resolution. Indirect evaluation of the approach shows small, but significant benefit, for information extraction tasks.

“…Extracting missing relations is not a new problem. Early work focused on a very limited domain (Palmer et al, 1986;Tetreault, 2002) or did not attempt to automate the task (Whittemore et al, 1991). This section focuses on more recent work.…”
