Abstract
The basic medium of interpersonal and mass communication is text (→ Text and Intertextuality). Analyzing text helps in understanding the meanings of mass media messages and their potential effects, observing strategies and developments of rhetoric, identifying rules and structures of social communication, etc. Thus text analysis, comprising all kinds of qualitative and quantitative techniques of media content, discourse, and linguistic analysis, is an indispensable methodological field for all social sciences (→ Content Analysis, Qualitative; Content Analysis, Quantitative; Discourse Analysis; Linguistics). But as communicators' encoding of → meaning and ideas (semantics) in text (syntax) does not always follow a straight logic and is heavily influenced by social and cultural context (→ Linguistic Pragmatics), the analysis of large text corpuses is a complicated and laborious endeavor. Therefore, from the beginning of computer science, scholars have tried to develop automated tools for understanding, abstracting, and classifying texts.
