Span-based joint entity and relation extraction augmented with sequence tagging mechanism

2022 · arXiv (Cornell University)

Span-based joint extraction simultaneously conducts named entity recognition (NER) and relation extraction (RE) in text span form. However, since previous span-based models rely on span-level classifications, they cannot benefit from token-level label information, which has …

A Privacy-Preserving Blockchain Platform for a Data Marketplace

2022 · Distributed Ledger Technologies Research and Practice

Recent data leak scandals, together with the under-utilization of collected data (estimated that around 90% of data never leaves a device’s local storage), limits the applicability and potential of novel data driven applications. Thus, novel …

Active Temporal Knowledge Graph Alignment

2023 · International Journal on Semantic Web and Information Systems

Entity alignment aims to identify equivalent entity pairs from different knowledge graphs (KGs). Recently, aligning temporal knowledge graphs (TKGs) that contain time information has aroused increasingly more interest, as the time dimension is widely used …
