Public Legal Education (PLE) websites have become one of the primary means of communication between the dominant organizer of PLE in China - the government - and the public. This study aims to construct a general automatic evaluation mechanism for Public Legal Education Texts (PLET) on the basis of Discourse Information Theory (DIT), and three specific research questions are raised as follows:

1. What core values serve as the criteria for readers to evaluate PLET?

2. What are the discourse information representations (DIRs) and discourse information patterns (DIPs) that reflect the evaluation values?

3. How can the general automatic evaluation mechanism be realized?

Both qualitative and quantitative methodologies are utilized accordingly. The book first explores the eight core evaluative values and three valid evaluative concepts in the readers’ cognition. Discourse Information Analysis (DIA) is then conducted both from macro and micro perspectives to identify valid DIRs and DIPs for distinguishing evaluative score sections of each evaluative concept. Finally, a general evaluation mechanism is constructed consisting of four modules with C#. It is hoped that the automation of the evaluation mechanism can contribute to the promotion of the linguistic findings of this research in the circle of PLE.
