The primary goal of this project is to advance a new class of search engines to provide social network users with the ability to harness the growth of data, where both internal user-generated data and external web data can be systematically captured, continuously retrieved and summarized.
Project title: Personalized search over the streaming and heterogeneous social media data
Project dates: 2018 onward
Grants and funding: Google Faculty Research Award
This project is done by the Big Data & Database Group at RMIT led by A/Prof. Zhifeng Bao.
Social networks like Facebook and Twitter are hubs for users to acquire up-to-date information on the Internet. Apart from information generated within social networks, external information (from the Internet) of higher quality and selectivity is shared by users in social networks and can be accessed as well. The primary goal of this project is to advance a new class of search engines to provide social network users with the ability to harness the growth of data, where both internal user-generated data and external web data can be systematically captured, continuously retrieved and summarized. Organizing Internet content around social media will create a novel way to search for contents on the Internet compared to conventional search engines.
It designs lightweight and update-efficient indexes to manage heterogenous data that is evolving temporally.
It investigates novel data structures to capture the lifespan and propagation of microblog entries, thereby capturing a story line with more content and relationships of related microblogs, which are missed in existing search engines that only find an independent list of individual microblogs.
It develops novel summarization techniques to preserve important properties such as the distinguishable textual contents, propagation patterns in Social Network Platforms and social popularity of the story line.
This project uses the connectivity of the internet as a means to develop dynamic congregation and easy access to all forms of user-generated data, including the content generated in social media and the content of conventional websites shared via social media.
