Personally I would say "No." Here we see the use of the present subjunctive. Regardless of the subject, the form of the present subjunctive verb is the infinitive unpreceded by "to". It can be used to emphasise urgency or importance. Some people however allege that the present subjunctive is obsolete or at least becoming more rarely used.
It is important that Watson (a computer program)
have the right source content.
It is important that he
be there.
In British English it is quite common to use the word "should" before the verb e.g. It is important that Watson
should have the right source content.
