Glyce: Glyph-vectors for Chinese Character Representations

2019 · arXiv (Cornell University)

It is intuitive that NLP tasks for logographic languages like Chinese should benefit from the use of the glyph information in those languages. However, due to the lack of rich pictographic evidence in glyphs and …

DC-BERT: Decoupling Question and Document for Efficient Contextual Encoding

2020

Recent studies on open-domain question answering have achieved prominent performance improvement using pre-trained language models such as BERT. State-of-the-art approaches typically follow the "retrieve and read" pipeline and employ BERT-based reranker to filter retrieved documents …

Transferring Causal Mechanism over Meta-representations for Target-Unknown Cross-domain Recommendation

2024 · ACM Transactions on Information Systems

Tackling the pervasive issue of data sparsity in recommender systems, we present an insightful investigation into the burgeoning area of non-overlapping cross-domain recommendation, a technique that facilitates the transfer of interaction knowledge across domains without …

BrowseComp-Plus: A More Fair and Transparent Evaluation Benchmark of Deep-Research Agent

2025 · arXiv (Cornell University)

Deep-Research agents, which integrate large language models (LLMs) with search tools, have shown success in improving the effectiveness of handling complex queries that require iterative search planning and reasoning over search results. Evaluations on current …
