In general: Bleu measures precision: how much the words (and/or n-grams) in the machine generated summaries appeared in the human reference summaries. Rouge measures recall: how much the words (and/or n-grams) in the human reference summaries appeared in the machine generated summaries. Naturally – these results are complementing, as is often the case in precision … Read more
I made that wikipedia contraction-to-expansion page into a python dictionary (see below) Note, as you might expect, that you definitely want to use double quotes when querying the dictionary: Also, I’ve left multiple options in as in the wikipedia page. Feel free to modify it as you wish. Note that disambiguation to the right expansion … Read more

This is exactly the sort of stuff that Perl was designed to do, so it doesn’t surprise me that it’s faster. One easy optimization in your Python code would be to precompile those regexes, so they aren’t getting recompiled each time. exists_re = re.compile(r’^(.*?) INFO.*Such a record already exists’) location_re = re.compile(r’^AwbLocation (.*?) insert into’) … Read more
grep . FILE (And if you really want to do it in sed, then: sed -e /^$/d FILE) (And if you really want to do it in awk, then: awk /./ FILE)
you have to open the file in append mode, which can be achieved by using the FileWriter(String fileName, boolean append) constructor. output = new BufferedWriter(new FileWriter(my_file_name, true)); should do the trick
