Actually i am doing some similarity calculation between a document and query. I have calculated the term frequency for the query. But i do not know how to calculate the tern frequency for EACH words inside a document. Can anyone guide me ? Thank you for your attention.

Answer 1

You can use a HashMap, where key is your term and value - the frequency of it. Each time you see you term you increase the value. After the file is done you have your numbers.

Answer 2

是的，使用HashMap保存值并浏览文件，您可以使用扫描仪

Answer 3

In Java you should definitely stay with HashMap<String, Integer> . The terms will be the HashMap keys and the term frequency the value.
