When I started with research work, I found that it is way too difficult to find important source of information and research papers. It requires a lot of research to find potential research papers. However, later it has been observed that there are some key points to identify potential research papers. In every domain, there are multiple review and survey papers which claim to identify important challenges and gaps in the research papers,
However, it is difficult to track those research work which, years go, are left in between. Such research papers are said to be sleeping beauties.
Backtrack Research Paper Chain
One of the possible solution to identify potential research papers is to backtrack the research work. Once you identify one research paper, using its references, you may find great works prior to the present work. This goes on so on and so forth. Now this chain is possible only if we find great base paper of the research domain.
If you are studying Abraham Lincoln, try to find some letters he himself wrote. Maybe you could find an original newspaper clipping of interviews with the people closest to him. Journal entries are great finds, too.
Base paper is the research work which one refers as a key research work in the similar research area and on the similar challenges and/ or gaps.
However, due to availability of large number of research papers it is difficult to find the path breaking work which have been done in the related areas.
Journal and Conference Papers
The conference papers having high visibility and high citation number may lead to great research work. The papers which are citing such research papers must have been published in good (SCI/ SCIE) indexed journals and/ or in good (Core A/ A* ranked) conferences. Such journals and conferences show good research papers.
It is even better to check the number of citations, year of publication (recent ones are better), author h-index (better if high), age of the challenging research problem (smaller is better) and more number of recent citations. It is good to find best paper research awards in core A* ranked conferences, if you have not yet decided your research domain.
Playing with words
The literature work is the most important phase for any research work. It is important to identify all the papers related to the relevant research gaps in your domain. This is so because during thesis submission, this is one of the key aspect which is asked in different ways as indicated in Top 40 potential PhD viva questions about your thesis. Playing with words is the key idea behind identifying all the available research work in a specific domain. There are many such sleeping beauties which are left untouched since many recent years which could have been improved. This is due to lack of awareness that research papers having indifferent titles. I have come across some research papers which are very interesting but are unidentifiable to normal keywords. Check these:
I may talk in English but gaali toh Hindi mein hi denge: A study of English-Hindi code-switching and swearing pattern on social networks
Are We Birds of the Same Feather?
Though these are interesting articles and have contributed in their domains. But it is difficult track or notice and hence, have low visibility comparatively.
It is usually good practice to follow standard sites and links for fetching good research papers. These sites are Google Scholar, Science Direct and DBLP specially for Computer science related research work. This is same for all engineering backgrounds. These resources should be used to find different relevant research works. However, in order to make your profile, you must register with Google Scholar, Research Gate and Academia. This is an important step to get indulge with fellow researchers.

There are several topics and terminologies which are unclear when we begin with any research work. In order to understand these, you must follow wikipedia, where it also mentions the introductory research paper for any given technique or algorithm. The existing algorithms are, however, being used for different research domains these days. These are improved significantly with respect to different parameters and scenarios of research challenges.
Good Luck!!! Happy Research!!!
