See, when we write a thesis, we include more than 1000 words in it, the result of which is that we are able to explain our research work in a better way. That is why having more words is also compulsory.
And here we use main keywords in our thesis, so that when your guide or researcher wants to read your thesis, he can already guess by looking at your main keywords, which main keywords you have used, to solve your research question.
Because the researcher many times tries to find in his database all the work of people who have worked under the researcher in the past related to the keywords on which he has worked.
That is why main keywords are used in the thesis and these are always shown before or along with the abstract so that your researcher can find all that research work from his past database by looking at these main keywords and can see whether the work done in the past under those main keywords is going to be added in this field with the help of these keywords. That is why main keywords are used in the thesis.
And here you can quickly understand with the help of keywords, which problem you have solved, just by looking at these main keywords, abstract and result, hence for getting a quick overview of the thesis we have to include main keywords in our thesis.
It is like if you want to know the economic conditions of the person in front of you, then you can know how many assets he has, whether they are digital assets or physical assets.
Generally people look at physical assets, but today’s digital youth just give priority to digital assets because they like working while sitting at one place, preferably at home, as compared to going out in the midday.
And your thesis can have a maximum of 5-8 main keywords, with the help of which you can represent your thesis work in a better way in front of your researchers.
And these generally appear after you write the abstract. What happens is that, first you get an overview with the help of the abstract of the problem you want to solve, whereas after writing the main keywords in the abstract, you get to know about all those main keywords, using which you have solved the problem that you have tried to solve in your abstract. Hence the main keywords are written in your thesis.
Now whatever you have worked on here in keywords, that thing can also be new, so that is why it becomes necessary to write about it.
This happens because sometimes those things are new for your guide or researchers also, due to which it becomes important for you to compulsorily show those main keywords in your thesis.
