Data-driven multi-criteria decision making with marketing applications


Project Description

Applications are invited for a fully-funded three year PhD to commence in October 2019.

The PhD will be based in the Faculty of Business and Law, and will be supervised by Professor Alessio Ishizaka and Dr Giovanni Pino.

The work will look at:
-developing a state-of-the art review of existing data-driven multi-criteria decision methods;
-developing a data-driven multi-criteria decision method based on sentiment analysis;
-validating the method in a marketing context.

Project description
It is well known that optimal decisions are fundamentals for companies but also for individuals. Thus, it is not surprising that multi-criteria decision analysis has undergone a considerable expansion in recent years (Figueira et al. 2016), as a large number of methodologies have been developed and used in multiple contexts (lshizaka and Nemery 2013). However, these methods require a direct input from the decision-maker. If a decision-maker is unavailable, the multi-criteria decision method cannot be used. Furthermore, if the decision applies to a large group of people (e.g. which product to launch on the market), it is unlikely that a single decision-maker can represent all the parties. It is, therefore, important to develop new data-driven techniques based on secondary data, which do not require a direct input of a decision-maker.

To this end, we propose to use sentiment analysis to extract consumer preferences from social networks. Previous research has investigated how multi-criteria ratings allow consumers to assess whether or not a product or a service matches their expectations. However, previous research has rarely investigated how companies may employ such ratings to develop new products or services (Lin 2018). In particular, very little effort has been made so far to assess whether consumer emotions, as expressed through text, images, or videos, on the social media, may provide guidance for multi-criteria decision making related to the development of new products and services (Jannach et al. 2014). This research aims to enhance the field of multiple criteria decision analysis by incorporating sentiment analysis from social media.

The new methodology will be validated with a marketing case study. Secondary data will be collected from social media, which has two advantages: i) individuals can express themselves freely, and ii) data is available in large quantities. Multi-criteria decision-making literature (Bous et al. 2010) shows that consumers consider a variety of attributes in a holistic manner to arrive at a decision compatible with their preferences. Thus, because multiple attributes shape consumer decisions to adopt or resist new products, companies could benefit from a decision method that considers these attributes and their relative importance. Such a method may, in fact, help them design or improve different aspects of their offerings.
