individual_project_interim_report/introduction/introduction.tex

+\chapter{Introduction}
+
+In this chapter, we will first discuss the motivations behind the project and then specify its main objectives.
+
+\section{Motivations}
+
+People spend an ever growing share of their earnings online, from purchasing daily necessities on e-commerce sites such as Amazon\footnote{https://www.amazon.com/} to streaming movies on services such as Netflix\footnote{https://www.netflix.com/}. As the market shifts online, people's purchase decisions are increasingly based on product reviews either accompanying the products on their e-commerce sites, or on specialised review websites, such as Rotten Tomatoes\footnote{https://www.rottentomatoes.com/} for movies. These reviews can be written by fellow consumers who have purchased the product or by professional critics, such as in the latter example, but what unites most online review platforms is the massive number of individual reviews: a particular type of electronic toothbrush can have more than 10,000 reviews on Amazon\footnote{https://www.amazon.com/Philips-Sonicare-Electric-Rechargeable-Toothbrush/dp/B00QZ67ODE/}. As people cannot possibly go through all of the individual reviews, purchase decisions are often based on various kinds of review aggregations. The presentation of a review aggregation must be concise and intuitive in order to be effective, but it must also retain some nuances of the original reviews, so that consumers can understand \textit{why} a product is considered good or bad and if the arguments align with their individual preferences. \par
+Clear explanations of review aggregations can also be used to improve e-commerce site recommender systems, as it has been shown that explanations can help to improve the overall acceptance of a recommender system \cite{RefWorks:doc:5e2f3970e4b0241a7d69e2a4}, and recommendations are often largely based on review aggregations such as average user ratings. 
+
+\section{Objectives}
+
+There have already been some attempts to improve explanations for review aggregations, some of which are discussed in Chapter 2. One such attempt is what is called an Argumentative Dialogical Agent (ADA), proposed by Cocarascu et al.\ \cite{RefWorks:doc:5e08939de4b0912a82c3d46c} and implemented for the Rotten Tomatoes and Trip Advisor\footnote{https://www.tripadvisor.com/} platforms \cite{RefWorks:doc:5e0de20ee4b055d63d355913}. The goal of this project is to extend upon the work of Cocarascu et al. in order to design and implement a more generalised ADA to provide explanations for Amazon product reviews. The main objectives for the extended agent are threefold:
+
+\begin{itemize}
+  \item \textbf{Generalise} the agent to work with a larger variety of different products. Currently ADA has only been implemented for movie and hotel reviews, two highly homogeneous domains in which there is not much variance in key features and review language from one product to another. Implementing ADA for Amazon reviews will require more general NLP methods in extracting review aggregations.
+  \item \textbf{Enhance dialogue} between the user and the agent to support conversational search. Currently, the agent is able to respond to a limited number of questions centred solely around explanations for a single product review aggregation. Given the large amounts of current research into explainable recommender systems and the potential of ADA in this domain, we will extend its dialogue to support conversational search.
+  \item \textbf{Learn} from user feedback. The enhanced agent should be able to query and implement information and opinions provided by the user to improve its review aggregations and product recommendations.
+\end{itemize}
+
+In addition to the above, we will implement a conversational user interface for the ADA on the Alexa\footnote{https://www.amazon.com/b?\&node=13727921011/} virtual assistant. The user interface will provide the user with a novel way to obtain explainable product recommendations using voice commands on Alexa-compatible smart speakers.
