从不同的 JSON 文件创建语料库

Question

我想创建一个由以 JSON 格式存储的不同文章的正文组成的语料库。它们位于以年份命名的不同文件中，例如：

with open('Scot_2005.json') as f:
    data = [json.loads(line) for line in f] 

对应于 2005 年的《苏格兰人报》。此外，该报的其余文件名为：APJ_2006....APJ2015。还。我还有另一份报纸，苏格兰每日邮报，它仅从 2014 年到 1015 年发行：SDM_2014, SDM_2015。我想创建一个包含所有这些文章正文的通用列表：

doc_set = [d['body'] for d in data]

我的问题是循环我发布的代码的第一部分，以便数据对应于所有文章，而不仅仅是给定年份的给定报纸的文章。关于如何完成这项任务的任何想法？在我的尝试中，我尝试使用 Pandas：

for i in range(2005,2016):
    df = pandas.DataFrame([json.loads(l) for l in open('Scot_%d.json' % i)])

doc_set = df.body

在我看来，这种方法的问题是：它不会追加所有年份；我不知道如何包括 2005-15 年以外时间间隔的其他报纸。此方法的结果如下所示：

Answer 1

假设你有一个文件列表：

file_name_list = ( 'Scot_2005.json', 'APJ_2006.json' )

您可以append 到这样的列表：

data = list()
for file_name in file_name_list:
    with open(file_name, 'r') as json_file:
        for line in json_file:
            data.append(json.loads(line))

如果您想以编程方式创建file_name_list，可以使用glob 库。
