A Conceptual Framework for Enhancing Product Search with Product Information from Reviews

Product search today is limited, as users can only search and filter for a restricted set of product features, e.g. 15” and 1TB hard disk when searching for a laptop. The often decision- critical aspects of a product are however hidden in user reviews (“noisy fan” or “bright display”) and are not available until a product has been found. This paper proposes a conceptual framework for the integration of product aspects, that have been mined and derived from consumer reviews, into the product search. The framework structures the challenges that arise in four major fields and gives an overview of existing research for each one of them: Data challenges, user experience challenges, purchase process challenges and business challenges. It may inform researchers from various disciplines to perform target-oriented research as well as practitioners what to consider when building up such an enriched product search

Inferring Networks of Substitutable and Complementary Products

In a modern recommender system, it is important to understand how products relate to each other. For example, while a user is looking for mobile phones, it might make sense to recommend other phones, but once they buy a phone, we might instead want to recommend batteries, cases, or chargers. These two types of recommendations are referred to as substitutes and complements: substitutes are products that can be purchased instead of each other, while complements are products that can be purchased in addition to each other. Here we develop a method to infer networks of substitutable and complementary products. We formulate this as a supervised link prediction task, where we learn the semantics of substitutes and complements from data associated with products. The primary source of data we use is the text of product reviews, though our method also makes use of features such as ratings, specifications, prices, and brands. Methodologically, we build topic models that are trained to automatically discover topics from text that are successful at predicting and explaining such relationships. Experimentally, we evaluate our system on the Amazon product catalog, a large dataset consisting of 9 million products, 237 million links, and 144 million reviews.Comment: 12 pages, 6 figure

Probabilistic Inference of Twitter Users' Age based on What They Follow

Twitter provides an open and rich source of data for studying human behaviour at scale and is widely used in social and network sciences. However, a major criticism of Twitter data is that demographic information is largely absent. Enhancing Twitter data with user ages would advance our ability to study social network structures, information flows and the spread of contagions. Approaches toward age detection of Twitter users typically focus on specific properties of tweets, e.g., linguistic features, which are language dependent. In this paper, we devise a language-independent methodology for determining the age of Twitter users from data that is native to the Twitter ecosystem. The key idea is to use a Bayesian framework to generalise ground-truth age information from a few Twitter users to the entire network based on what/whom they follow. Our approach scales to inferring the age of 700 million Twitter accounts with high accuracy.Comment: 9 pages, 9 figure

A Survey on Feature Recommendation Techniques

Recommendation systems are a very common now days and it is used in a variety of applications. A recommender system that is designed to reduce the human effort of performing domain analysis. Domain analysis is the task in which we can find the commonality and difference between the different software’s of same domain ‘feature recommendation is very useful now a days. This approach relies on data mining techniques to discover common features across products as well as the relationship among these common features. In this paper we used different techniques which are used for domain analysis and feature recommendation. This approach mines descriptions of product from publicly available online product descriptions, uses a text mining and a novel incremental diffusive clustering algorithm to discover features in specific domain , uses association rule mining to know latent relationships between the features within the products of same domain and uses KNN algorithm which generates a probabilistic feature model that represents commonalities, variant.

Data standardization

With data rapidly becoming the lifeblood of the global economy, the ability to improve its use significantly affects both social and private welfare. Data standardization is key to facilitating and improving the use of data when data portability and interoperability are needed. Absent data standardization, a “Tower of Babel” of different databases may be created, limiting synergetic knowledge production. Based on interviews with data scientists, this Article identifies three main technological obstacles to data portability and interoperability: metadata uncertainties, data transfer obstacles, and missing data. It then explains how data standardization can remove at least some of these obstacles and lead to smoother data flows and better machine learning. The Article then identifies and analyzes additional effects of data standardization. As shown, data standardization has the potential to support a competitive and distributed data collection ecosystem and lead to easier policing in cases where rights are infringed or unjustified harms are created by data-fed algorithms. At the same time, increasing the scale and scope of data analysis can create negative externalities in the form of better profiling, increased harms to privacy, and cybersecurity harms. Standardization also has implications for investment and innovation, especially if lock-in to an inefficient standard occurs. The Article then explores whether market-led standardization initiatives can be relied upon to increase welfare, and the role governmental-facilitated data standardization should play, if at all

Social Product Search – Enhancing Product Search with Mined (Sparse) Product Features

Search functionality in web shops is limited today. Consumers can only search for a restricted set of standard product features for each product group. A major part of the relevant information, especially reviews, is only available as an extension to the product description, that is, after a product has been found and therefore quite late in the purchase process. With the growing numbers of reviews, reading review texts is a burden for consumers, and there is a need to rearrange and organize user-generated content. Integrating mined product features into the product search might therefore add value to the customer experience. Following design science principles, we propose an approach to mine frequent product feature sets from social media content and enhance product search with sets of product features to create a “social product search”. We contribute a design science artefact in form of a situated implementation. For illustration, we present an example for the product group notebooks with 22480 reviews of 2745 products that we crawled from amazon.com. Further, we depict three application scenarios how mined frequent product feature sets can be integrated into the product search and enhance the consumer search experience
