I.                  Theoretical Expounding

    The Discourse Information Theory is highly compatible in that various linguistic theories can be applied to deal with language phenomena at different levels for the discourse research. As we have noted, the discourser information lies between the linguistic surface structure and cognitive deep structure. Therefore, different linguistic theories contribute differently to the discourse information analysis and the researchers are required to be very clear of the position of the theory integrated in the research and, most importantly, to expound it elaborately.

II.               Analysis of the Object

    As a common practice to researchers in different fields, the analysis of objects and the choice of appropriate theory are subject to continuous alternation until an integrating point is arrived. Different studies call for distinct concrete analytic objectives. Specifically speaking, what variables from which level are dealt with in what perspective depends on the specific research projects. For instance, to decide the nature of a ransom letter differs directionally than deciding the authorship of it. For the former, the analysis mainly focuses on the contents, the functions, the linguistic performance and the psychological effects of the discourse information. On the contrary, the information patterning rules, the distribution of the information kernels, the assembly of the information elements and the routines of the linguistic behaviors are necessary for the latter. The substantive analysis actually begins only after the research object is properly dissected.

III.           Analysis of the Materials

Analysis of the materials is the core of the process of discourse information analysis, which, different than the analysis of those non-discursive facets such as lexical items and sentences, necessarily focuses on the globality of the discourse. Every single analysis result of the identical discourse is closely related and globality must be taken into consideration to rule out any possible contradiction. In practice, a timely correlation analysis of the results from various perspectives is needed at different stages and such analysis is aimed at testing the validity of the research and render modifications if necessary.

The results of the material analysis can be roughly classified as qualitative and quantitative. If the research objective is quantitative, the sample size of the materials, the coverage of the information elements and the sample size of the information elements are all to be defined accurately and a pilot study usually helps.

IV.           Interpretation and Assumption

    When the result of the discourse information analysis is interpreted, biases are likely to occur due to overgeneralization of the small sample size, overgeneralization of the information elements, omission of some important contents, contradictory interpretations to the results from different analytical methods and so forth. These biases need to be reinspected according to the theory concerned to find the reasons. The assumption based on the analysis is usually biased similarly to the result of the interpretation. The problem is , sometimes, the bias in the assumption can not be spotted and modified according to the specific theory employed in the research. Consequently, the researcher needs to be very cautious when making assumptions.
