- Authors: Muhao Chen, Hongming Zhang, Haoyu Wang, Dan Roth
- Abstract summary: This paper studies a new cognitively motivated semantic typing task, multi-axis event process typing.
We develop a large dataset containing over 60k event processes, featuring ultra fine-grained typing on both the action and object type axes.
We propose a hybrid learning framework, P2GT, which addresses the challenging typing problem with indirect supervision from glosses1and a joint learning-to-rank framework.

- Abstract: This paper studies a new cognitively motivated semantic typing task,
multi-axis event process typing, that, given an event process, attempts to
infer free-form type labels describing (i) the type of action made by the
process and (ii) the type of object the process seeks to affect. This task is
inspired by computational and cognitive studies of event understanding, which
suggest that understanding processes of events is often directed by recognizing
the goals, plans or intentions of the protagonist(s). We develop a large
dataset containing over 60k event processes, featuring ultra fine-grained
typing on both the action and object type axes with very large ($10^3\sim
10^4$) label vocabularies. We then propose a hybrid learning framework, P2GT,
which addresses the challenging typing problem with indirect supervision from
glosses1and a joint learning-to-rank framework. As our experiments indicate,
P2GT supports identifying the intent of processes, as well as the fine semantic
type of the affected object. It also demonstrates the capability of handling
few-shot cases, and strong generalizability on out-of-domain event processes.

Speech event detection is crucial for multimedia retrieval, involving the tagging of both semantic and acoustic events.
This paper tackles two primary challenges in speech event detection: the continual integration of new events without forgetting previous ones, and the disentanglement of semantic from acoustic events.
We propose a novel method, 'Double Mixture,' which merges speech expertise with robust memory mechanisms to enhance adaptability and prevent forgetting.

Event Detection aims to identify and classify mentions of event instances from unstructured articles.
Existing techniques for event detection only use homogeneous one-hot vectors to represent the event type classes, ignoring the fact that the semantic meaning of the types is important to the task.
We propose a Semantic Pivoting Model for Effective Event Detection (SPEED), which explicitly incorporates prior information during training and captures semantically meaningful correlations between input and events.

We leverage pre-trained language models to contextually represent pre-defined types for both event triggers and arguments.
We successfully map 83% of the triggers and 54% of the arguments to the correct types, almost doubling the performance of previous zero-shot approaches.
