Question. Identify organization and facility mentions in this White House visitor passage using the supplied ACE categories: “After the 9/11 attacks, the system changed radically. Now, anyone who wants to tour the White House must apply through the office of his or her representative in Congress, which forwards the names to the White House for clearance. Once they get the green light, visitors show up at the appointed time on 15th Street between E and F Streets and join the line to enter through the southeast gate. Anyone who has flown on an airline in recent years will recognize the familiar territory of identity checks and electronic scans, although you do get to keep your shoes on. At the head of the line, rangers from the National Park Service check photo IDs against a list of names.” [10 marks]
Answer
| Mention in order | Type | Reason |
|---|---|---|
| White House (tour) | FAC | Physical building being toured |
| office of his or her representative | ORG under administrative-office reading | Staff/organizational office receiving applications; no visit to the physical office is described |
| Congress | ORG | Legislative organization |
| White House (clearance) | ORG | Institution/staff granting clearance, a metonymic use |
| 15th Street | FAC | Transport infrastructure |
| E and F Streets | FAC (two coordinated streets) | Roads, not organizations |
| southeast gate | FAC | Physical entrance component |
| an airline | ORG generic mention | Organization operating flights; generic, not a proper named company |
| National Park Service | ORG | Government agency |
The prompt uses ACE entity mentions: nominal/generic mentions can be included, unlike a named-only tagger. 9/11 is an event/date mention, not ORG/FAC; visitors and rangers are people. If a narrower classroom guideline asks only named entities, omit the generic office/airline/gate spans and explicitly state that convention. Context decides whether White House means building or administration.
Source / convention note. Boundary and generic-mention decisions depend on the provided ACE annotation convention; the answer distinguishes them from a named-only interpretation.
