TALK: Prabhakar Raghavan: Beyond information retrieval: what does Search mean these days?
TITLE:
Beyond information retrieval: what does Search mean these days?
ABSTRACT:
Classic information retrieval systems aimed to retrieve the documents best matching a user’s query. The advent of the web dramatically changed this landscape and led to the creation of what is considered the modern day search engine. In this talk, we will explore this evolution and the nuanced questions that arise in the operation of a search engine at planetary scale: information quality vs. misinformation; limitations in query understanding, the corpus of content, and information fragmentation; and the economics and value exchange of web search. We are in the early stages of these staples being transformed by the advent of large language models. The future of search lies in the continued refinement of the interplay between evolving technologies, economic models, and user behaviors. We will delve into the new set of opportunities and challenges posed by this shift.
