经济趋势是非结构化数据么？要怎么理解呢

问题如下：

Text Analytics is appropriate for application to:

选项：

economic trend analysis.

large, structured datasets.

public but not private information.

解释：

A is correct.

Through the Text Analytics application of natural language processing (NLP), models using NLP analysis may incorporate non-traditional information to evaluate what people are saying—via their preferences, opinions, likes, or dislikes—in the attempt to identify trends and short-term indicators about a company, a stock, or an economic event that might have a bearing on future performance.

考点：Text Analytics and Natural Language Processing

解析：这道题考察的是文本分析。

A选项说文本分析可以用来分析经济趋势，这是正确的。

B选项说文本分析应用于大的，结构化的数据集。这是错误的，应该是大的、非结构化的数据集。

C选项说文本分析适用于公开的信息而不是私有的信息。这也是错误的，文本分析也可以适用于私有信息。
