Talk Title: FROM CONSTRAINED EVENT SEQUENCES GENERATION TO TEXT GENERATION
Abstract: REMINDER: Meeting hosts only admit guests that they know to the Zoom meeting. Hence, you're highly encouraged to use your USC account to sign into Zoom. If you're an outside visitor, please inform nlg DASH seminar DASH admin2 AT isi.edu beforehand so we'll be aware of your attendance and let you in.
Understanding events is a critical component of natural language understanding NLU. A key challenge lies in the fact that events can be described in different granularities. A coarse grained event e.g., publishing a paper can often be disseminated into a fine grained process of events e.g., writing the paper, passing the peer review, and presenting at the conference. In this work, we tackle the problem of goal oriented event process generation, where a task goal event, a process that completes this goal is automatically generated. We tackle this task with a constrained generation approach, inferring unobserved event chains based on existing sequences. To leverage prior knowledge to facilitate commonsense reasoning, we employ pre trained LMs to generate event sequences and to retrieve original stories.
Biography: Shanxiu He is an undergraduate at UCLA and a member of UCLANLP lab. Prior to the internship, her research interest focuses on pre rained Vision and Language models such as VisualBERT and ClipBert and their applications to various structural learning tasks. During this internship, she researches on event centric knowledge representation and specifically event sequences generations.
