Abstract  This paper proposes an improved DT method to identify the theme of the NASA 2011-2020 strategic plan based on multi-word phrases frequency analysis and phrases proximity analysis, adding the term identification of subject. Experiment proves that the improved DT method can identify the theme of documentation in full-text effectively and simply the work of intelligences to some extent.
Key wordsCo-word analysis      Theme identification      DT      Term identification
