A Summarization Journey: From Extraction to Abstraction – Vasudeva Varma (IIIT Hyderabad, India)
In this talk, I will be sharing my (and my team’s) research journey of building summarization engines to produce various flavors of summaries. Starting from single document summarization, our experience of building multi-document summarization (MDS), query focused MDS, Update or Progressive summarization, more recently guided summarization, comparison summarization and personalized summarization systems can be seen as movement from Extraction based to Abstraction based summary generation. We have used variations of Relevance Based Language Model (RBLM) along with external knowledge sources in building these systems.I will also be sharing our experience of participating in Knowledge Base Population (KBP) track of Text Analysis Conference (TAC) and how our recent approach to this problem is influenced by the summarization technology. Since 2006, our team has consistently performed well and ranked as a top team in various tracks of DUC (Document Understanding Conference) and TAC (Text Analysis Conference) conferences conducted by NIST.
