Literally it would translate to the right side of the world, but is often used as a phrase to refer to the right direction of a model, graphic, or positive X axis on a quadrant.

This may make sense if the text you are translating has a graphic representation of a "hype cycle", consisting of multiple stops. This figure might have something like "security" on the right before going into another stop called "analysis", before reaching part 3 which might be "data collection" or something along those lines as an example.

In reference 1, this phrase is used to refer to the Data stage of a cycle of Data and Models.

図を見てください。前回の図とよく似ていることからわかるように，前回の図の考え方を拡張したものです（前回は左側の円内に「母集団」，右側の円には「サンプル」と書かれていました）。私たちは現実の世界，この図で言えば右側の世界にいます。現実の世界で観測できるもの，それがデータです。では，私たちはデータの観測を通じて何が知りたいのでしょうか？

In example 2, this is used to refer to a region of a theoretical quadrant positive on the X axis, which he refers to as quadrants B and I.

キャッシュフロークワドラントの図形の左側に配置されたのがSとEであり、右側に配置されたのがBとIです。左側と右側の世界はお互いに、考え方や収入経路などがまるで異なった世界です。
