As you may recall, for my midterm project, I got stumped on several seemingly simple tasks. One of those—the most important, since upon it depends my semester-long assignment for Mainstreaming Information—was figuring out a way to compare one list of words to another and pull out the words that were unique to one of those lists. In my head, I can see very easily how this would be done. Given my special way of haphazardly flailing through code, however, I just couldn’t get it to work.

Until today!

In fiddling with the Bayesian comparison code for this week’s homework, I finally pulled out a list of unique words. Of course, this is a completely perverse misuse of that code—like using a steamroller to kill a pillbug—but as long as it works, I don’t fucking care.

So, here’s what I did. In BayesClassifier.java, I replaced the last two for loops with the following:

[java]for (String word: uniqueWords)
{
for (BayesCategory bcat: categories)
{
double wordProb = bcat.relevance(word, categories);
if (wordProb < 1) { println(word); } else {} } // end for bcat } // end for word for (BayesCategory bcat: categories) { double score = bcat.score(uniqueWords, categoryWordTotal); println("---The following words were not found in " + bcat.getName()); } // end for bcat[/java] And in BayesCategory.java I replaced the percentage and relevance blocks with [java] public double percentage(String word) { if (count.containsKey(word)) { return count.get(word); } // end if else { return 0.001; } // end else } // end percentage public double relevance(String word, ArrayList categories)
{
double percentageSum = 0;
for (BayesCategory bcat: categories)
{
percentageSum += bcat.percentage(word);
} // end for bcat
return percentage(word);
} // end relevance[/java]

So now, if I run the command

$ java BayesClassifier A2_unique.txt < B1_unique.txt | sort >results.txt

I get a list of words that are in B1_unique.txt (The Masada Scroll by Paul Block and Robert Vaughan, 2007) but not in A2_unique.txt (Zuleika Dobson or, An Oxford Love Story by Max Beerbohm, 1911). For example,
