The introduced papers here addressed this problem from deferent views, some deals with single-term indexing while others deal with phrase indexing, other researchers made comparisons between different techniques and gave us preferability to one against others based on some experimental results. On the other hand, some papers proposed new technique or made some enhancements on existing ones either depends on statistical or un-statistical methods. The rest of papers proposed tools as key-terms extractors to be used in text indexing.
