ZiNet: Linking Chinese Characters Spanning Three Thousand Years

1 code implementation Findings (ACL) 2022 Yang Chi, Fausto Giunchiglia, Daqian Shi, Xiaolei Diao, Chuntao Li, Hao Xu

In addition, powered by the knowledge of radical systems in ZiNet, this paper introduces glyph similarity measurement between ancient Chinese characters, which could capture similar glyph pairs that are potentially related in origins or semantics.

Towards a Gateway for Knowledge Graph Schemas Collection, Analysis, and Embedding

no code implementations21 Nov 2023 Mattia Fumagalli, Marco Boffo, Daqian Shi, Mayukh Bagchi, Fausto Giunchiglia

One of the significant barriers to the training of statistical models on knowledge graphs is the difficulty that scientists have in finding the best input data to address their prediction goal.

Toward Zero-shot Character Recognition: A Gold Standard Dataset with Radical-level Annotations

no code implementations1 Aug 2023 Xiaolei Diao, Daqian Shi, Jian Li, Lida Shi, Mingzhe Yue, Ruihua Qi, Chuntao Li, Hao Xu

To increase the adaptability of ACCID, we propose a splicing-based synthetic character algorithm to augment the training samples and apply an image denoising method to improve the image quality.

Recognizing Entity Types via Properties

no code implementations16 Apr 2023 Daqian Shi, Fausto Giunchiglia

Thus, the entity type (etype) recognition task is proposed to deal with such heterogeneity, aiming to infer the class of entities and etypes by exploiting the information encoded in ontologies.

Towards Ranking Schemas by Focus

no code implementations27 Feb 2023 Mattia Fumagalli, Daqian Shi, Fausto Giunchiglia

The main goal of this paper is to evaluate knowledge base schemas, modeled as a set of entity types, each such type being associated with a set of properties, according to their focus.

FCC: Feature Clusters Compression for Long-Tailed Visual Recognition

1 code implementation CVPR 2023 Jian Li, Ziyao Meng, Daqian Shi, Rui Song, Xiaolei Diao, Jingwen Wang, Hao Xu

Through representation learning, DNNs can map BFs into dense clusters in feature space, while the features of minority classes often show sparse clusters.

LiveSchema: A Gateway Towards Learning on Knowledge Graph Schemas

no code implementations13 Jul 2022 Mattia Fumagalli, Marco Boffo, Daqian Shi, Mayukh Bagchi, Fausto Giunchiglia

In this paper, we describe the LiveSchema initiative, namely a gateway that offers a family of services to easily access, analyze, transform and exploit knowledge graph schemas, with the main goal of facilitating the reuse of these resources in machine learning use cases.

RZCR: Zero-shot Character Recognition via Radical-based Reasoning

no code implementations12 Jul 2022 Xiaolei Diao, Daqian Shi, Hao Tang, Qiang Shen, Yanzeng Li, Lei Wu, Hao Xu

The long-tail effect is a common issue that limits the performance of deep learning models on real-world datasets.
