我是NLP的新手,需要帮助来从不包含句号的文本中提取句子。
例如:(下面的文字不包含句号)
global warming is the term used to describe a gradual increase in the average
temperature of the earths atmosphere and its oceans a change that is believed to
be permanently changing the earths climate there is great debate among many
people and sometimes in the news on whether global warming is real (some call it
a hoax) but climate scientists looking at the data and facts agree the planet is
warming while many view the effects of global warming to be more substantial and
more rapidly occurring than others do the scientific consensus on climatic
changes related to global warming is that the average temperature of the earth
has risen between 04 and 08 °c over the past 100 years the increased volumes of
carbon dioxide and other greenhouse gases released by the burning of fossil
fuels land clearing agriculture and other human activities are believed to be
the primary sources of the global warming that has occurred over the past 50
years scientists from the intergovernmental panel on climate carrying out global
warming research have recently predicted that average global temperatures could
increase between 14 and 58 °c by the year 2100 changes resulting from global
warming may include rising sea levels due to the melting of the polar ice caps
as well as an increase in occurrence and severity of storms and other severe
weather events

实际上,了解句子在何处开始和结束是一项相对昂贵的操作。对于您的情况,您可以列出一个不会以句子开头的单词列表,例如“地球”和“政府间”,将您的文本拆分为单词,检测大写单词(这些单词将以句子开头),然后将子列表加入字符串。这是我的操作方式:
