## 5 Conclusion

A new classification of emotions by grouping them into pairs based on certain mental processes underlying these emotions has been proposed. **This method** ignores the external expression of emotions completely. Elements **in each pair are** symmetrical with respect to each other in the sense that they contain identical sets of parameters that underlie them except that one element is a **negative** emotion while the other is a positive emotion. This classification uses these underlying parameters of emotions instead of treating emotions as **black boxes.**
It will be particularly useful for those who want to model emotions in **the field** of artificial intelligence.
