There have thousands of crimes are happening daily all around. But people
keep statistics only few of them, therefore crime rates are increasing day by
day. The reason behind can be less concern or less statistics of previous
crimes. It is much more important to observe the previous crime statistics for
general people to make their outing decision and police for catching the
criminals are taking steps to restrain the crimes and tourists to make their
travelling decision. National institute of justice releases crime survey data
for the country, but does not offer crime statistics up to Union or Thana
level. Considering all of these cases we have come up with an approach which
can give an approximation to people about the safety of a specific location
with crime ranking of different areas locating the crimes on a map including a
future crime occurrence prediction mechanism. Our approach relies on different
online Bangla newspapers for crawling the crime data, stemming and keyword
extraction, location finding algorithm, cosine similarity, naive Bayes
classifier, and a custom crime prediction model

该研究利用不同的在线新闻网站进行犯罪数据爬取、词干提取，运用了位置查找算法、余弦相似度、朴素贝叶斯分类器以及一种自定义的犯罪预测模型来估计特定地点的犯罪率，并对犯罪地点进行排名和预测未来的犯罪发生率。
