In the second major philosophical position that has influenced social science, coherence theory, truth, knowledge, and theory must fit within a coherent system of propositions. Such a system of propositions may be applied to specific cases only in accordance with properties of the general system (Hempel & Oppenheim, 1948). There may be one true knowledge system, or there may be many such systems, but in either case, coherency exists between specific facts and general propositions. Like correspondence theory, coherence theory is a traditional model of truth and knowledge that is closely associated with scientific positivism.

For text mining research, coherence theory implies that while there may be multiple ways to analyze online groups and communities, to be considered true the specific facts uncovered by text mining and analysis methods must fit within a coherent system of theoretical and empirical propositions.
