例如Zhen Wang[2]等人提出了采用双向RNN的方法来进行中文语义角色标注,网络结构如下所示: Feng Qian[3]提出将dependency tree structure通过architecture engineering的方法(而非feature engineering的方法)放入到LSTM cell中,能够充分利用句子的句法依存结果提高结果,网络结构如下所示。
LSA has been applied successfully in diverse language systems for calculating the semantic similarity of texts. LSA ignores the structure of sentences, i.e., it suffers from a syntactic blindness problem. LSA fails to distinguish between sentences that contain semantically similar words but have ...
we show how these cell ensembles accurately predicted the broad semantic categories of the words as they were heard in real time during speech and how they tracked the sentences in which they appeared. We also show how they encoded the hierarchical structure of these meaning representations and ho...
Large language model (LLM) systems, such as ChatGPT1or Gemini2, can show impressive reasoning and question-answering capabilities but often ‘hallucinate’ false outputs and unsubstantiated answers3,4. Answering unreliably or without the necessary information prevents adoption in diverse fields, with p...
非负矩阵分解(non-negative matrix factorization,NMF)是另一种矩阵的因子分解方法,其特点是分解的矩阵非负。非负矩阵分解也可以用于话题分析。 1. 单词向量空间、话题向量空间 1.1 单词向量空间 文本信息处理的一个核心问题是对文本的语义内容进行表示,并进行文本之间的语义相似度计算。
Use natural language:With the rise of voice search, it’s important to use natural language in your content, including conversational phrases and questions. Structure your content:Organize your content into clear sections and use headers to make it easier for semantic search engines to understand th...
ERNIE (Zhang等人,2019b)将结构性KG集成到预训练模型中,以改进知识驱动的NLP任务。相比之下,我们的目标是将KG的结构和语义结合起来,通过一个统一的优化过程来完成KG任务。KGBERT (Yao et al, 2019)将KG补全任务建模为句子分类任务,并通过微调预训练的LM来解决它们。我们的LASS和KGBERT之间有几个关键的区别(Yao...
Recursive Chunking: Recursive chunking divides the input text into smaller chunks in a hierarchical and iterative manner using a set of separators. If the initial attempt at splitting the text doesn’t produce chunks of the desired size or structure, the method recursively calls itself on the resu...
