Classifying entities into pre-defined labels 7355 c. Suppose that an NLP Engine wants to tag the sequence,"change is good using 3 possible tag A, B and C. The engine has the following probabilities information from training data: P(change(A)=1/5, P(change|B)=1/5, P(change|C)=4/5 uppos2/07/10 P(is|A)=2/5, P(is|B)=0, P(is|C)=0. P(good|A)=1/10, P(good|B)=1/3, P(good|C)=1/3 P(A/A)=1/5,P(BIA)=1/5,P(CIA)=3/5 P(A/B)=1/5,P(BIB)-8/10,P(CIB)=0 P(AIC)-2/3,P(BIC)=1/3,P(CIC)=0 Assume that all the tags have the same probabilities at the beginning of the sentence (and that is 1/3 each). Find out the best tag sequence using the Viterbi algorithm along with value at each vertex. [5marks] d. Given the emission probabilities and transition probabilities find the correct pos tag for the sentence using HMM. Possible Tags are (VB, TO,
d. Given the emission probabilities and transition probabilities find the correct pos tag for the sentence using HMM. Possible Tags are (VB, TO, NN, PPSS). Assume all the POS tags are equally likely to be at the starting of the sequence [5 marks] "I ran to summit" <S> VB TO NN PPSS VB 0.04 0.05 0.1 0.35 0.2 TO 0 0.5 0 0.05 0.7 NN 0.3 0.4 0.9 0.1 0.05 PPSS 0.66 0.05 0 0.5 0.05
