Question: There are two Classes, C1 and C2. The total number of documents in the training set is 50, and the number of documents belonging to

There are two Classes, C1 and C2. The total number of documents in the training set is 50, and the number of documents belonging to C1 is 30. The following table shows the probability of P(Xi | Cj). Given a document D1 that contains some terms shown in the table.

(6%) Please use the Naive Bayesian document classification method to determine which Class does D1 belong to.
(3%) Briefly explain the main idea of Probabilistic Model (Multinomial model) for document classification.
(4%) Briefly explain the Vector Space Model (VSM). Explain tf_ij, logNdfj and the formula w_ij = tf_ij× logNdfj (for term t_j of the document D_i)

Table			Document D1
Term(Xi)	P(Xi\|C1)	P(Xi\|C2)	Document term	Frequency
X1	3/16	1/16	X1	0
X2	1/16	1/8	X2	2
X3	1/4	1/4	X3	2
X4	5/32	3/16	X4	0
X5	1/32	1/8	X5	1
X6	1/16	1/16	X6	2
X7	1/8	1/16	X7	1
X8	1/8	1/8	X8	0
