Polar Question

Because users can respond in any manner to polar questions some user responses may lead to some false-positives. Hence, developers are encouraged to build custom recognizers for positive and negative sentences. However, by using the following entity types the developer is solely responsible for any action executed by the Bot.

Entity Name	Description	Examples	Returned Value
@sys.positive	A positive response	Yes  Okay	Returns string, such as yes
@sys.negative	A negative response	No  Nope	Returns string, such as no

手动设置

Currency

As the word dollar may be used to refer to United States Dollar in US and Australian Dollar in Australia. The developer must manually extend the @sys.currency.name entries by adding synonyms for currency codes based on the location of the user the bot is interacting with.

Bot.Recognizers[EntityTypes.CurrencyName].Entries.AddSynonyms("USD", new [] {"dollar", "us dollar","dollars"})

OrderStyle

@sys.date recognizer has an OrderStyle property that enables regional date time parsing. The default value of MonthDayYear can be changed based on the location where the bot is deployed to accept different date formats like mm/dd/yy, mm/dd/yyyy, mm-dd-yy

You may change the order style prior to training the bot as shown below.

var bot = new OscovaBot();
var dateRecogizer = (Bot.Recognizers["sys.date"] as DateRecognizer);
dateRecogizer.OrderStyle = OrderStyle.DayMonthYear;
