Once you defined a 'similitude test', that is a method establishing if the passed strings are similar or not you could apply such a method to the string pairs in your list and increment the counter whenever the test is passed.
Writing a method testing the similarity of the strings it is not a trivial task and heavily depends (as noted by Sergey) on your requirements.

sample code:

Java

List<string> list = new ArrayList<string>();
list.add("aaa");
list.add("bbb");
list.add("aaa");

Set<string> unique = new HashSet<string>(list);
for (String key : unique) {
    System.out.println(key + ": " + Collections.frequency(list, key));
}</string></string></string></string>
