给出一个英文文本，让GPT模型生成一个程序来计算特定单词在文本中出现的次数。


text = "Big data refers to the use of data sets that are so voluminous and complex that traditional data processing application software is inadequate to deal with them."
word = "data"
以下是一个Python程序，用于计算文本中特定单词出现的次数。在此示例中，我们将计算单词"data"的出现次数：

```
text = "Big data refers to the use of data sets that are so voluminous and complex that traditional data processing application software is inadequate to deal with them."
word = "data"

# 将单词转换为小写以进行不区分大小写的匹配
word = word.lower()

# 分割文本成单词列表
words = text.lower().split()

# 计数器
count = 0

# 遍历单词列表并搜索匹配项
for w in words:
    if w == word:
        count += 1

# 打印结果
print("出现次数：", count)
```

运行此程序，将输出以下结果：

```
出现次数： 2
```
