Fertility issues are closely related to population security, in 60 years
China's population for the first time in a negative growth trend, the change of
fertility policy is of great concern to the community. 2023 "two sessions"
proposal "suggests that the country in the form of legislation, the birth of
the registration of the cancellation of the marriage restriction" This topic
was once a hot topic on the Internet, and "unbundling" the relationship between
birth registration and marriage has become the focus of social debate. In this
paper, we adopt co-occurrence semantic analysis, topic analysis and sentiment
analysis to conduct multi-granularity semantic analysis of microblog comments.
It is found that the discussion on the proposal of "removing marriage
restrictions from birth registration" involves the individual, society and the
state at three dimensions, and is detailed into social issues such as personal
behaviour, social ethics and law, and national policy, with people's sentiment
inclined to be negative in most of the topics. Based on this, eight proposals
were made to provide a reference for governmental decision making and to form a
reference method for researching public opinion on political issues.Comment: 7 pages, 4 figures, 1 tabl
