Hi PP -
my VBD -

is NN -

<s>
Her PP
name VBD
is DT
the NN
same WRT

</s>

I tried to use the following awk
Code:
awk '{print $1 "\t" $2 "\t" "-"}'

but I can not figure out how to include the
Code:
<s>

and
Code:
</s>

in between each sentence.
Any suggestions?
Hello owwow14,

Could you please try following and let me know if this helps you.
Code:
awk -vs="<s>" -vs1="</s>" 'function add_tags(A){if(A==1){$0=s ORS $0};if(A==2){$0=$0 ORS s1}}($0 ~ /^$/){next} (NR==1 || j==1){add_tags(1);j=0} ($0==". SENT"){add_tags(2);j=1} 1'  Input_file

Output will be as follows.
Code:
<s>
Hi PP
my VBD
name DT
is NN
. SENT
</s>
<s>
Her PP
name VBD
is DT
the NN
same WRT
. SENT
</s>

Also a non oneliner form of the solution is as follows.
Code:
awk -vs="<s>" -vs1="</s>" 'function add_tags(A){
                                                if(A==1)        {
                                                                        $0=s ORS $0};
                                                                                        if(A==2){
                                                                                                        $0=$0 ORS s1
                                                                                                }
                                                                }
                                                ($0 ~ /^$/)     {
                                                                        next
                                                                }
                                                (NR==1 || j==1) {
                                                                        add_tags(1);
                                                                        j=0
                                                                }
                                                ($0==". SENT")  {
                                                                        add_tags(2);
                                                                        j=1
                                                                }
                           1
                          ' Input_file
