27. TF-IDF lets you set up?

a. most regularly occurring phrase in doc
b. the
most essential phrase within the doc

Reply: b)

TF-IDF helps to ascertain how essential a selected phrase is within the context of the doc corpus. TF-IDF takes into consideration the variety of occasions the phrase seems within the doc and is offset by the variety of paperwork that seem within the corpus.

  • TF is the frequency of phrases divided by the full variety of phrases within the doc.
  • IDF is obtained by dividing the full variety of paperwork by the variety of paperwork containing the time period after which taking the logarithm of that quotient.
  • Tf.idf is then the multiplication of two values TF and IDF.

Suppose that we’ve got time period depend tables of a corpus consisting of solely two paperwork, as listed right here:

Time period Doc 1 Frequency Doc 2 Frequency
This 1 1
is 1 1
a 2  
Pattern 1  
one other    2
instance   3

The calculation of tf–idf for the time period “this” is carried out as follows:

for "this"
-----------
tf("this", d1) = 1/5 = 0.2
tf("this", d2) = 1/7 = 0.14
idf("this", D) = log (2/2) =0
therefore tf-idf
tfidf("this", d1, D) = 0.2* 0 = 0
tfidf("this", d2, D) = 0.14* 0 = 0
for "instance"
------------
tf("instance", d1) = 0/5 = 0
tf("instance", d2) = 3/7 = 0.43
idf("instance", D) = log(2/1) = 0.301
tfidf("instance", d1, D) = tf("instance", d1) * idf("instance", D) = 0 * 0.301 = 0
tfidf("instance", d2, D) = tf("instance", d2) * idf("instance", D) = 0.43 * 0.301 = 0.129

In its uncooked frequency type, TF is simply the frequency of the “this” for every doc. In every doc, the phrase “this” seems as soon as; however as doc 2 has extra phrases, its relative frequency is smaller.

An IDF is fixed per corpus, and accounts for the ratio of paperwork that embody the phrase “this”. On this case, we’ve got a corpus of two paperwork and all of them embody the phrase “this”. So TF–IDF is zero for the phrase “this”, which suggests that the phrase is just not very informative because it seems in all paperwork.

The phrase “instance” is extra attention-grabbing – it happens 3 times, however solely within the second doc.
