Relevancy Evaluator¶

This notebook uses the RelevancyEvaluator to measure if the response + source nodes match the query.
This is useful for measuring if the query was actually answered by the response.

The Battle of Long Island was the largest battle of the American Revolutionary War that took place in New York City.	=== American Revolution === The Stamp Act Congress met in New York in October 1765, as the Sons of Liberty organization emerged in the city and skirmished over the next ten years with British troops stationed there. The Battle of Long Island, the largest battle of the American Revolutionary War, was fought in August 1776 within the modern-day borough of Brooklyn. After the battle, in which the Americans were defeated, the British made the city their military and political base of operations in North America. The city was a haven for Loyalist refugees and escaped slaves who joined the British lines for freedom newly promised by the Crown for all fighters. As many as 10,000 escaped slaves crowded into the city during the British occupation. When the British forces evacuated at the close of the war in 1783, they transported 3,000 freedmen for resettlement in Nova Scotia. They resettled other freedmen in England and the Caribbean. The only attempt at a peaceful solution to the war took pl...

As of April 2016, 69% of registered voters in the city are Democrats and 10% are Republicans.

A Republican candidate for statewide office has not won all five boroughs of the city since it was incorporated in 1898. In 2012, Democrat Barack Obama became the first presidential candidate of any party to receive more than 80% of the overall vote in New York City, sweeping all five boroughs.

In its 2018 ParkScore ranking, the Trust for Public Land reported that the park system in New York City was the ninth-best park system among the fifty most populous U.S. cities. ParkScore ranks urban park systems by a formula that analyzes median park size, park acres as percent of city area, the percent of city residents within a half-mile of a park, spending of park services per resident, and the number of playgrounds per 10,000 residents. In 2021, the New York City Council banned the use of synthetic pesticides by city agencies and instead required organic lawn management. The effort was started by teacher Paula Rogovin's kindergarten class at P.S. 290. ==== National parks ==== Gateway National Recreation Area contains over 26,000 acres (110 km2), most of it in New York City. In Brooklyn and Queens, the park contains over 9,000 acres (36 km2) of salt marsh, wetlands, islands, and water, including most of Jamaica Bay and the Jamaica Bay Wildlife Refuge. Also in Queens, the park includes a significant portion of the western Rockaway Peninsula, most notably Jacob Riis Park and Fort Tilden. In Staten Island, it includes Fort Wadsworth, with historic pre-Civil War era Battery Weed and Fort Tompkins, and Great Kills Park, with beaches, trails, and a marina. The Statue of Liberty National Monument and Ellis Island Immigration Museum are managed by the National Park Service and are in both New York and New Jersey. They are joined in the harbor by Governors Island National Monument. Historic sites under federal management on Manhattan Island include Stonewall National Monument; Castle Clinton National Monument; Federal Hall National Memorial; Theodore Roosevelt Birthplace National Historic Site; General Grant National Memorial (Grant's Tomb); African Burial Ground National Monument; and Hamilton Grange National Memorial. Hundreds of properties are listed on the National Register of Historic Places or as a National Historic Landmark.	Fail
2	New York has witnessed a growing combined volume of international and domestic tourists, reflecting over 60 million visitors to the city per year, the world's busiest tourist destination. Approximately 12 million visitors to New York City have been from outside the United States, with the highest numbers from the United Kingdom, Canada, Brazil, and China. Multiple sources have called New York the most photographed city in the world.I Love New York (stylized I ❤ NY) is both a logo and a song that are the basis of an advertising campaign and have been used since 1977 to promote tourism in New York City, and later to promote New York State as well. The trademarked logo, owned by New York State Empire State Development, appears in souvenir shops and brochures throughout the city and state, some licensed, many not. The song is the state song of New York. The majority of the most high-profile tourist destinations to the city are situated in Manhattan. These include Times Square; Broadway theater productions; the Empire State Building; the Statue of Liberty; Ellis Island; the United Nations headquarters; the World Trade Center (including the National September 11 Memorial & Museum and One World Trade Center); the art museums along Museum Mile; green spaces such as Central Park, Washington Square Park, the High Line, and the medieval gardens of The Cloisters; the Stonewall Inn; Rockefeller Center; ethnic enclaves including the Manhattan Chinatown, Koreatown, Curry Hill, Harlem, Spanish Harlem, Little Italy, and Little Australia; luxury shopping along Fifth and Madison Avenues; and events such as the Halloween Parade in Greenwich Village; the Brooklyn Bridge (shared with Brooklyn); the Macy's Thanksgiving Day Parade; the lighting of the Rockefeller Center Christmas Tree; the St. Patrick's Day Parade; seasonal activities such as ice skating in Central Park in the wintertime; the Tribeca Film Festival; and free performances in Central Park at SummerStage.Points of interest have also developed in the city outside Manhattan and have made the outer boroughs tourist destinations in their own right.
