Papers with information retrieval system
Topology-of-Question-Decomposition: Enhancing Large Language Models with Information Retrieval for Knowledge-Intensive Tasks (2025.coling-main)
Copied to clipboard
| Challenge: | Large language models (LLMs) are constrained to chaining immediate reasoning steps and relying solely on parametric knowledge. |
| Approach: | They propose a framework that activates retrieval only when necessary to improve answer accuracy. |
| Outcome: | Experiments show that the proposed framework improves performance in knowledge-intensive tasks. |
Are “Undocumented Workers” the Same as “Illegal Aliens”? Disentangling Denotation and Connotation in Vector Spaces (2020.emnlp-main)
Copied to clipboard
| Challenge: | popular pretrained models encode both denotation and connotation as one entangled representation . a researcher using a pretrained representation can confuse words with connotations . |
| Approach: | They propose a nerual netowrk that decomposes a pretrained representation as independent denotation and connotation representations. |
| Outcome: | The proposed model improves document rankings by comparing denotation and connotation representations with extrinsic representations. |
Leveraging Medical Literature for Section Prediction in Electronic Health Records (D19-1)
Copied to clipboard
| Challenge: | Prior approaches to section prediction have only used text data from EHRs and required significant manual annotation. |
| Approach: | They propose to use sections from medical literature to train models to predict sections in EHRs. |
| Outcome: | The proposed model uses sections from medical literature that contain similar content to those found in EHR sections. |
UniRetriever: Multi-task Candidates Selection for Various Context-Adaptive Conversational Retrieval (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing methods for retrieving information from a large corpus of data are sub-optimal and low efficiency. |
| Approach: | They propose a multi-task framework that functions as a universal retriever for three dominant retrieval tasks during the conversation. |
| Outcome: | The proposed framework can perform persona selection, knowledge selection, and response selection tasks simultaneously. |
