  text: This paper deals with online customer reviews of local multi-service providers.
    While many studies investigate product reviews and online labour markets with
    service providers delivering intangible products “over the wire”, we focus on
    websites where providers offer multiple distinct services that can be booked,
    paid and reviewed online but are performed locally offline. This type of service
    providers has so far been neglected in the literature. This paper analyses reviews
    and applies sentiment analysis. It aims to gain new insights into local multi-service
    providers’ performance. There is a broad literature range presented with regard
    to the topics addressed. The results show, among other things, that providers
    with good ratings continue to perform well over time. We find that many positive
    reviews seem to encourage sales. On average, quantitative star ratings and qualitative
    ratings in the form of review texts match. Further results are also achieved in
    this study.

  text: Analysts have estimated that more than 80 percent of today’s data is stored
    in unstructured form (e.g., text, audio, image, video)—much of it expressed in
    rich and ambiguous natural language. Traditionally, to analyze natural language,
    one has used qualitative data-analysis approaches, such as manual coding. Yet,
    the size of text data sets obtained from the Internet makes manual analysis virtually
    impossible. In this tutorial, we discuss the challenges encountered when applying
    automated text-mining techniques in information systems research. In particular,
    we showcase how to use probabilistic topic modeling via Latent Dirichlet allocation,
    an unsupervised text-mining technique, with a LASSO multinomial logistic regression
    to explain user satisfaction with an IT artifact by automatically analyzing more
    than 12,000 online customer reviews. For fellow information systems researchers,
    this tutorial provides guidance for conducting text-mining studies on their own
    and for evaluating the quality of others.
