SimCloud: Similarity-aware Data Analysis in Cloud-based Systems

Similarity-aware operations, e.g., Similarity Join, Similarity Selection, and Similarity Grouping, are among the most useful data processing and analysis operations. Multiple application scenarios need to perform this operation over large amounts of data. Internet companies, for instance, collect massive amounts of data such as content produced by web crawlers or service logs, and can use similarity queries to gain valuable understanding of the use of their services, e.g., identify customers with similar buying patterns, generate recommendations, perform correlation analysis, etc. Cloud systems and MapReduce, its main framework for distributed processing, constitute an answer to the requirements of processing massive amounts of data in a highly scalable and distributed fashion.

The main goals of the SimCloud project are to study, design, implement and evaluate similarity operators for cloud systems. We are particularly interested on techniques that use the MapReduce framework.

Paper accepted in the International Conference on Data Engineering (ICDE '17)! (Jan., 2017)

Our research paper "Fast and Scalable Distributed Set Similarity Joins for Big Data Analytics" co-authored by C. Rong, C. Lin, Y. N. Silva and J. Wang has been accepted in the 33rd International Conference on Data Engineering (ICDE 2017). The paper proposes an efficient approach to solve the set similarity join problem using an novel partitioning approach that avoids the generation of duplicate records. We look forward to presenting our work in San Diego, CA, USA.

Paper accepted in the International Conference on Similarity Search and Applications (SISAP '16)! (Aug., 2016)

The paper "An Experimental Survey of MapReduce-based Similarity Joins" co-authored by Y.N. Silva, three previous undergraduate students (J.M. Reed, A. Wadsworth, and K. Brown) and a visiting scholar (C. Rong.) has been accepted in the 9th International Conference on Similarity Search and Applications (SISAP 2016). The paper focuses on the study, classification and experimental comparison of previously proposed Similarity Join algorithms for Big Data. We look forward to presenting our work in Tokyo, Japan.

Paper accepted in Frontiers of Computer Science (FCS) (Feb., 2016)

The paper "String Similarity Join with Different Similarity Thresholds Based on Novel Indexing Techniques" coauthored by C. Rong, Y. N. Silva and C. Li. has been accepted in the Frontiers of Computer Science journal (FCS). In this paper, we focus on the study of similarity operators that support multiple similarity thresholds.

NCUIRE Award Supports the SimCloud Project (May 2015)

NCUIRE Adelbert (A.J.) Wadsworth, one of our SimCloud team members, has received an NCUIRE Scholarship award to work with Prof. Silva during the summer of 2015. As part of this project, A.J. and Prof. Silva will explore Similarity Grouping techniques for Big Data. NCUIRE is a New College (ASU) program that supports meaningful research collaborations between faculty and undergraduates. Congratulations to A.J. and Prof. Silva!

We received Amazon Research and SRCA Grants! (April, 2015)

Amazon Our proposal "Similarity Grouping for Big Data" recently received an Amazon Web Services (AWS) Research grant. In addition, our proposal "Study, Classification and Benchmarking of Similarity Join Algorithms for Big Data" was awarded a grant from the Scholarship, Research and Creative Activities Grant Program (SRCA) at ASU - New College. We look forward to keep working on developing new techniques to identify similarities in large datasets.

CRC Book Chapter!

CRC Press Our team wrote a chapter for the Geographical Information Systems: Trends and Technologies book to be published in March 2014 (CRC). The chapter, Similarity Join for Big Geographic Data, focuses on the study of highly scalable similarity joins with geographic data and distance functions.
