Proceedings of the 2015 Workshop on Large-Scale and Distributed System for Information Retrieval

Abstract

The publication date is one day earlier then the EST date to provide the proceedings to attendees in Australian on the first day of the conference The LSDS-IR workshop series aims to attract researchers from the industry and academia to present and discuss problems, ideas, and recent research results related to the performance of large-scale and distributed information retrieval systems. The workshop plays an important role in the information retrieval community as a venue where early work addressing the workshop's topics are discussed and matured. The LSDS-IR'15 workshop continues the efforts of the following workshops organized in the past: P2PIR (collocated with SIGIR'05, CIKM'06, and CIKM'07), HDIR (collocated with SIGIR'08), and LSDS-IR (collocated with SIGIR'07, CIKM'08, SIGIR'09, SIGIR'10, CIKM'11, WSDM'13, WSDM'14). As in the previous years, the workshop provides space for researchers to discuss the scalability and efficiency issues in largescale and distributed information retrieval systems and to define new directions for the field. This year's LSDS-IR workshop has attracted five submissions from Europe (Sweden, Germany, Russia), Asia (India), and South America (Chile). Three of these submissions were accepted for presentation as long papers, and one submission was accepted for presentation as short paper. The workshop program also includes the following two invited talks: "Large-Scale Real-Time Data Management for Engagement and Monetization", Simon Jonassen (Cxense), "Count or Not to Count: Counting Challenges for Big Spatial Data Analytics", Egemen Tanin (University of Melbourne).
