Technical writing task

Conduct a literature review/survey (work carried out in this area) of keywords spotting/extraction in lecture videos and write up to 800-1000 words. I don't need a summary of a single paper as relevant literature review but summary of what others have done in this area/field with inline references. This is very much like the "Introduction" part of any scientific paper. Need to use the references from ieee explore, acm or springer. All references should be of published research articles from any of these three forums. I can provide you with login details of ieee explore ([login to view URL]). You may search for similar queries in ieee explore to search for the papers (query example: keyword extraction from lecture videos) to write review on. Search for 12-15 relevant papers and conduct a literature review about them. I need one para giving a brief introduction about keywords, keywords extraction process and related information. In second and third para you may write about what others have used (i.e. the techniques and methods used), their proposed system and approaches. If you've any questions please feel free to ask. Budget: 25 usd. Domain: computer vision, image/video processing, keywords example (but not limited to): keyword extraction, keyword spotting, lecture videos, blackboard etc.
