基于义原表示学习的词向量表示方法(Word Representation based on Sememe Representation Learning)
“本文利用知网(HowNet)中的知识,并将Word2vec模型的结构和思想迁移至义原表示学习过程中,提出了一个基于义原表示学习的词向量表示方法。首先,本文利用OpenHowNet获取义原知识库中的所有义原、所有中文词汇以及所有中文词汇和其对应的义原集合,作为实验的数据集。然后,基于Skip-gram模型,训练义原表示学习模型,进而获得词向量。最后,通过词相似度任务、词义消歧任务、词汇类比和观察最近邻义原,来评价本文提出的方法获取的词向量的效果。通过和基线模型比较,发现本文提出的方法既高效又准确,不依赖大规模语料也不需要复杂的网络结构和繁多的参数,也能提升各种自然语言处理任务的准确率。”

Improved Word Representation Learning with Sememes
Sememes are minimum semantic units of word meanings, and the meaning of each word sense is typically composed by several sememes. Since sememes are not explicit for each word, people manually annotate word sememes and fo…
Common Sense ReasoningLanguage ModelingLanguage ModellingMachine Translation+6The Analysis about Building Cross-lingual Sememe Knowledge Base Based on Deep Clustering Network
A sememe is defined as the minimum semantic unit of human languages. Sememe knowledge bases (KBs), which contain words annotated with sememes, have been successfully applied to many NLP tasks, and we believe that by lear…
Deep ClusteringGlyph Enhanced Chinese Character Pre-Training for Lexical Sememe Prediction
Sememes are defined as the atomic units to describe the semantic meaning of concepts. Due to the difficulty of manually annotating sememes and the inconsistency of annotations between experts, the lexical sememe predicti…
Unsupervised Neural Aspect Extraction with Sememes
Aspect extraction relies on identifying aspects by discovering coherence among words, which is challenging when word meanings are diversified and processing on short texts. To enhance the performance on aspect extraction…
