Editing Authorship detection: 2010 group (section)

====Jie Dong====
'''Progress and Status this week:'''
# Algorithm update:
#* The new version of trigram extraction algorithm inserts a "#" before a sentence and a "$" after a sentence. For example, there is a string "Today is a good day. I want to go to picnic."After TextEditor class, it will becomes "# Today is a good day & # I want to go to picnic $"
#* The motivation to this modification is because in an English text, each sentence exists relatively independent with each other. In terms of the example above, "......a good day. I want ......", it is not necessary to calculate the probability of apperance of "I" after the bigram "good day". Instead, it will be more significant to characterise an author's writing habit by knowing the probability of apperance of "I" in the start of a sentence, i.e. after the bigram "$ #". Likewise, the probability of a word appearing at the end of the sentence is important to know as well, that is "day $ #".In addition, by this method, we can discover how often is a specific word used in one sentence
#* To determine the beginning and end of a sentence, delimiter "." is used. In the future, with further study of English text characteristics, there might be more delimiters
# Generate classification results based on Federalist Text.


'''Plan and Goals for new week:'''
# Perform more tests on different disputed texts
# Try another key words selection algorithm: based on occurring frequency
