I'm definitely no expert in naming chords but here are some things to keep in mind.
If you're given a three note chord like EGC or CEG or GCE, without context, it is a C major triad. How can you tell which is the root note? You find the note among the three, such that the other two are in a 3-5 relationship.
So for GCE:
If G was the root then C and E would be the 4 and the 6
If E was the root then G and C would be the 3 and the 6
If C was the root then E and G would be the 3 and the 5. So the root note is C and the chord is a C major triad.
Even if it's an inversion C/G or C/E it is still a C major triad.
You could also interpret it depending on its function.
So if EADGBe in the Key of D is acting as:
the i chord with D as the root it would be D6/9sus4/E R-2-4-5-6
the ii chord with E as the root it would be Em11 R-m3-4-5-m7
the IV chord with G as the root it would be G6/9/E R-2-3-5-6
the V chord with A as the root it would be A9/11sus2/E R-2-4-5-m7
the vi chord with B as the root it would be Bm11#5/E R-m3-4-#5-m7
the names I got from following website. The rationale for the names is given.

So its best to think of it as an Em11 chord. Em11 because it has R-b3-5, E is the bass note and it's not functioning as a I, IV V or vi chord.
