Search for text contained in a text file and remove them from another text file in java -

-

i have text file output java program finds frequency of people's names mentioned in multiple documents , writes them file (peoplenames.txt) this:

article1location\article1 name1:countofname1# name2:countofname2# name3:countofname3# ... article2location\article2 name1:countofname1# name2:countofname2# name3:countofname3# ... article3location\article3 name1:countofname1# name2:countofname2# name3:countofname3# ...

the names correspond people names identified in each article along frequency appear in article, there 90,000 articles. have text file (titles.lst) contains list of 40 different titles , abbreviations (such mr., mrs., president, sir etc.) use list in file search , remove these titles peoplenames.txt. not sure how go in java new java , need modify original code in java produced peoplenames.txt accommodate title removal.

my program identifying person such mr john smith different john smith, removing titles give me more accurate count of names mentioned in articles.

thanks in advance help.

you can use regular expressions remove instances: public class test {

    public static void main( string[] args ) throws exception {         string s = "mr tom , ms jane";         s = s.replaceall("\\bmr\\b|\\bms\\b", "");         system.out.println(s);     }

for sake of explaining comments:

    public static void main( string[] args ) throws exception {         string [] titles = args;         string regex = "\\b"+titles[0]+"\\b";         (int i=1; i<titles.length; i++) {             regex += "|\\b" + titles[i] + "\\b";         }          string s = "mr tom , ms jane";         s = s.replaceall(regex, "");         system.out.println(s);     }

you can use replace option repeatedly rather building regular expression. don't know quicker. hazard guess depends on java implementation.

    public static void main( string[] args ) throws exception {         string [] titles = args;         string s = "mr tom , ms jane";         (int i=1; i<titles.length; i++) {             s = s.replaceall("\\b"+titles[0]+"\\b", "");         }         system.out.println(s);     }

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
