Exploratory mining of collaborative social content

Content Provider ACM Digital Library
Author Das, Mahashweta
Abstract The widespread use and growing popularity of online collaborative content sites (e.g., Yelp, Amazon, IMDB) has created rich resources for users to consult in order to make purchasing decisions on various items such as restaurants, e-commerce products, movies, etc. It has also created new opportunities for producers of such items to improve business by designing better products, composing succinct advertisement snippets and building smart personalized recommendation systems. This motivates us to develop a framework for exploratory mining of user feedback on items in collaborative content sites. Typically, the amount of user feedback associated with item(s) can easily reach hundreds or thousands of ratings, tags or reviews, resulting in an overwhelming amount of information, which users may find difficult to cope with. For example, popular restaurants listed in the review site Yelp routinely receive several thousand ratings and reviews. Moreover, most online activities involve interactions between multiple items and different users, and interpreting such complex user-item interactions becomes intractable too. My PhD research concerns developing novel data mining and exploration algorithms, that account for the above-mentioned challenges, for performing aggregate analytics over available user feedback. Our analysis goal is focused towards helping (a) content consumers make more informed judgment (e.g., if a user will enjoy eating at a particular restaurant), as well as (b) content producers conduct better business (e.g., a re-designed menu to attract more people of a certain demographic group to a restaurant). My dissertation identifies a family of mining tasks, and proposes a suite of algorithms - exact, approximation with theoretical properties, and efficient heuristics - for solving the problems. We conduct a comprehensive set of experiments on the proposed techniques over both synthetic and real data crawled from the web to validate the effectiveness of our framework.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
