Dear Internet Researchers: I am delivering a demo to my department faculty, titled: Text Data in Marketing: Data Sources, Linguistic Features, and Software Programs. I request you to critique my coverage and suggest changes/additions. As the title indicates, I will cover the following three aspects: 1. Show, via an example, text data in marketing: a. firm-generated (e.g., earnings calls) b. consumer/user-generated text data (e.g., Twitter) c. other-generated, marketing-relevant text data. Other could include market stakeholders (competitors, suppliers, organizational customers) and nonmarket stakeholders (news media, consumer organizations, regulators, legislators) I will take the example of the Volkswagen emissions scandal and show how this event led to text data generated by Volkswagen and its varied marketing stakeholders. I will mention various secondary data sources that my colleagues can use to obtain/buy text data. If you know of any other source, or an example more insightful than Volkswagen, please help me. 2. I will then proceed to discuss linguistic features of the text. These features include sentiment, emotion, cognition, named entities, readability, subjectivity, structural complexity, lexical complexity, and topic modeling/mining. I choose these features because I have used them in my research and can talk about them. If you know of any other useful feature that I am missing, please respond. 3. Software programs, both paid (e.g., LIWC) and free R/Python libraries, that take text as input and output the above linguistic features. I will start with LIWC, explain its variables from psychological standpoint. I will then demo syuzhet and sentimentr showing how their output variables offer new and different insights relative to LIWC. I will mention other R and Py packages such as TensorFlow, MXNet, and TextBlob). I will demo MALLET GUI for topic modeling. I will then mention how researchers can use MTurk to annotate their text data and then write a classifier (or hire a Py programmer to write it for them). If you know of any paid software program (that is as easy to use as LIWC) or any other R/Py package, please suggest. Thank you!
