In computing, a slot is an empty position on the motherboard where you can plug in expansion cards. In a PC, you may also refer to the slots as memory slots or AGP (accelerated graphics port) slots. A slot can also refer to a computer bus connection, such as the PCI slot or SATA (Serial ATA) connector.
In aviation, a slot is an authorization for a planned aircraft operation at a particular airport during a specific time period. It is used in the United States and other countries to control air traffic at busy airports, and prevent repeated delays caused by too many flights trying to take off or land at the same time.
A slot is a narrow opening or groove in something, such as a door, window, or piece of machinery. You can also use the word to describe a position in a game of poker, where winning involves lining up certain symbols on the pay line of a slot machine. In the US, some casinos have special slot machines that award players with free drinks or food, or even hotel rooms, if they play certain amounts of money.
In the context of bots, a slot is a place in an utterance where the bot can find information it needs to complete the request. Each identified slot must be mapped to a slot type that tells the bot what information to look for. For example, the bot can identify a slot in an utterance like “I want two executive rooms for three nights starting tomorrow” by mapping the keywords to the built-in slot types Rooms required and Date. You can also create custom slot types to match patterns in utterances, such as location slots to mark up cities for a travel bot.
