[Objective] This paper aims to identify the actual value of numerical indicators from the scientific literatures. [Methods] Firstly, we analyzed the Shortest-Path-Tree between the indicator and the digital entities. Then, we used by distant supervision to learn the syntactic and description characteristics of the numerical indicator sentence. Third, we created four types of relationship templates of more than, less than, equal and times. Finally, we obtained the real value of these indicators. [Results] We examined the proposed method in the fields of climate changes and astronomy. The F-values were 82.35% and 77.55%, which were above the average of related studies. [Limitations] We did not investigate the indicator real value across multiple sentences. [Conclusions] The proposed method could help us obtain the actual value of numerical indicators effectively.
