INSTRUCTIR: A Benchmark for Instruction Following of Information Retrieval Models

1 code implementation22 Feb 2024 Hanseok Oh, Hyunji Lee, Seonghyeon Ye, Haebin Shin, Hansol Jang, Changwook Jun, Minjoon Seo

Enhancing the capability of retrievers to understand intentions and preferences of users, akin to language model instructions, has the potential to yield more aligned search targets.

KTRL+F: Knowledge-Augmented In-Document Search

2 code implementations14 Nov 2023 Hanseok Oh, Haebin Shin, Miyoung Ko, Hyunji Lee, Minjoon Seo

We introduce a new problem KTRL+F, a knowledge-augmented in-document search task that necessitates real-time identification of all semantic targets within a document with the awareness of external sources through a single natural query.

Zero-Shot Dense Video Captioning by Jointly Optimizing Text and Moment

no code implementations5 Jul 2023 Yongrae Jo, Seongyun Lee, Aiden SJ Lee, Hyunji Lee, Hanseok Oh, Minjoon Seo

This is accomplished by introducing a soft moment mask that represents a temporal segment in the video and jointly optimizing it with the prefix parameters of a language model.

Nonparametric Decoding for Generative Retrieval

1 code implementation5 Oct 2022 Hyunji Lee, Jaeyoung Kim, Hoyeon Chang, Hanseok Oh, Sohee Yang, Vlad Karpukhin, Yi Lu, Minjoon Seo

The generative retrieval model depends solely on the information encoded in its model parameters without external memory, its information capacity is limited and fixed.

Generative Multi-hop Retrieval

1 code implementation27 Apr 2022 Hyunji Lee, Sohee Yang, Hanseok Oh, Minjoon Seo

A common practice for text retrieval is to use an encoder to map the documents and the query to a common vector space and perform a nearest neighbor search (NNS); multi-hop retrieval also often adopts the same paradigm, usually with a modification of iteratively reformulating the query vector so that it can retrieve different documents at each hop.
