によるとAccording to

Both derive from よる ('to be based on'), but are used differently. によると・によれば means 'according to' and is used to report information, e.g. 天気予報によると雨が降るそうです ('According to the weather forecast, it will rain.') によって・による often means 'depending on' and has broader uses, including cause, method, or basis, e.g. 人によって考え方が違う ('Ways of thinking vary depending on the person.')

Both involve a basis or source, but differ in usage. によると・によれば reports information, e.g. 天気予報によると雨が降るそうです ('According to the weather forecast, it will rain.') をもとに means doing something based on a source or foundation, e.g. 事実をもとに小説のストーリーを考えた ('I thought up a story for a novel based on true events.')

によると・によれば reports second-hand information, e.g. 新聞によると事件があったそうです ('According to the newspaper, there was an incident.') にもとづいて indicates that an action is grounded in something like rules or facts, e.g. 法律にもとづいて判断する ('Make a decision based on the law.')

Both can translate as 'according to', but differ in usage. にしたがって means 'in accordance with' or 'following' something, e.g. 説明書に従って組み立てた ('I assembled it according to the manual.') によると・によれば expresses reported information, e.g. 説明書によると操作は簡単です ('According to the manual, the operation is simple.')
