给定两个文本，计算它们之间的相似度。
以下是两个英文文本的例子：
"Apple's iPhone sales have been declining in recent years due to increased competition from Samsung and other Android-based smartphones."
"Samsung's latest Galaxy S10 model has received rave reviews for its innovative features, powerful hardware, and stunning design."
可以使用自然语言处理技术，例如文本向量化或词嵌入，计算文本相似度，如余弦相似度或欧几里得距离。具体方法取决于所需的相似度计算和文本预处理步骤。
