This paper introduces the concepts and origins of Technology Readiness Levels(TRL) briefly and distinguishes TRL from related concepts, like technology life cycle. Then, much emphasis is put on the widely adopted NASA TRL system, and its characteristics description and research framework, as well as its applied values, assessment tools and limitation of applications are also described. At the end, two methods, including latent semantic indexing and co-word analysis, are carefully examined on the probability of identification of TRLs.

Key wordsTechnology readiness level      R&D management      Technology readiness assessment      Co-word analysis
      Database tomography
