A constitution is the highest legal document of a country and serves as a
guide for the establishment of other laws. The constitution defines the
political principles, structure, hierarchy, position, and limits of the
political power of a country's government. It determines and guarantees the
rights of citizens. This study aimed at topic modeling of Iranian laws. As part
of this research, 11760 laws were collected from the Dotic website. Then, topic
modeling was conducted on the title and content of the regularizations using
LDA. Data analysis with topic modeling led to the identification of 10 topics
including Economic, Customs, Housing and Urban Development, Agriculture,
Insurance, Legal and judicial, Cultural, Information Technology, Political, and
Government. The largest topic, Economic, accounts for 29% of regulations, while
the smallest are Political and Government, accounting for 2%. This research
utilizes a topic modeling method in exploring law texts and identifying trends
in regularizations from 2016-2023. In this study, it was found that
regularizations constitute a significant percentage of law, most of which are
related to economics and customs. Cultural regularizations have increased in
2023. It can be concluded any law enacted each year can reflect society's
conditions and legislators' top concerns.
