In this age of information and big data, when people's information sources have been vastly improved thanks to the proliferation of the Internet, which has also altered the manner in which people obtain information, the search engine, which is the product of the combination of text retrieval and the World Wide Web, has become extremely popular. This study deduces a judgement retrieval technique employing keyword retrieval, which is able to achieve keyword retrieval of text documents from inside a text database. The research on vector model and named entity recognition was used to get to these conclusions.
