摘要:

我们提出了Charagram嵌入,一个简单的方法学习基于字符的组成模型嵌入文本序列。一个单词或句子使用字符n-gram计数向量表示,然后进行单个非线性变换以产生低维嵌入。我们使用三个任务进行评估:单词相似性,句子相似性和词性标记。我们证明了Charagram嵌入优于基于字符级递归和卷积神经网络的更复杂的架构,在几个相似性任务上实现了新的最先进的性能。

英文摘要:

We present Charagram embeddings, a simple approach for learning character-based compositional models to embed textual sequences. A word or sentence is represented using a character n-gram count vector, followed by a single nonlinear transformation to yield a low-dimensional embedding. We use three tasks for evaluation: word similarity, sentence similarity, and part-of-speech tagging. We demonstrate that Charagram embeddings outperform more complex architectures based on character-level recurrent and convolutional neural networks, achieving new state-of-the-art performance on several similarity tasks.
