The rate of crime is increasing rapidly and many citizens of country are the victims of these crimes. It is observed that though the number of crimes taking place is very huge, the actual number of crimes being reported to the legal authorities is very small. This huge difference is because of several reasons where one of the reason is lack of awareness about the civil rights and the laws. Many citizens in India are unaware about the evil practices performed against them and unethical exploitation of them done by others. The citizens are also not aware about various laws in the Indian Penal Code. So inorder to bridge this gap between the laws and the common citizens of India, we have proposed a Natural Language Processing (NLP) system using Word Mover’s Distance (WMD) which takes as input the textual description of crime and generates as output, the applicable Indian Penal Code (IPC) sections and the description of the punishments men- tioned under these sections. The performance comparison of WMD with cosine similarity is presented. Finally, the accuracy of the system is measured by getting the result generated by the system to be validated by a lawyer personal.

A common man is usually not literate about his civil rights and ends up being taken advantage. Right from a shopkeeper selling less quantity of goods to illegal business practices by an organization, crime is present everywhere. The helpless citizen unaware of his rights, freedom and social choices often fall prey to exploitation by evil retailers, business holders and other people who show haughty behavior to these people. Due to fear and lack of knowledge, the victims eschew taking any actions to avoid the drudgery of legal works. Even if some of the victims of these unethical works approach the lawyers, some of the lawyers may demand huge fees for just a bunch of advice and if the lawyer turns out to be venal, they pull off in exchange of being well paid by the culprits. The unreported crimes also include other crimes against the silent crowd. According to the survey, the © Springer Nature Singapore Pte Ltd. 2019 M. Singh et al.
