Patent Query Formulation by Synthesizing Multiple Sources of Relevance Evidence
Parvaz Mahdabi, Fabio Crestani
Article No.: 16
DOI: 10.1145/2651363

Patent prior art search is a task in patent retrieval with the goal of finding documents which describe prior art work related to a query patent. A query patent is a full patent application composed of hundreds of terms which does not represent a...

Matrix Factorization with Explicit Trust and Distrust Side Information for Improved Social Recommendation
Rana Forsati, Mehrdad Mahdavi, Mehrnoush Shamsfard, Mohamed Sarwat
Article No.: 17
DOI: 10.1145/2641564

With the advent of online social networks, recommender systems have became crucial for the success of many online applications/services due to their significance role in tailoring these applications to user-specific needs or preferences. Despite...

Browse-to-Search: Interactive Exploratory Search with Visual Entities
Shiyang Lu, Tao Mei, Jingdong Wang, Jian Zhang, Zhiyong Wang, Shipeng Li
Article No.: 18
DOI: 10.1145/2630420

With the development of image search technology, users are no longer satisfied with searching for images using just metadata and textual descriptions. Instead, more search demands are focused on retrieving images based on similarities in their...

Exploiting Representations from Statistical Machine Translation for Cross-Language Information Retrieval
Ferhan Ture, Jimmy Lin
Article No.: 19
DOI: 10.1145/2644807

This work explores how internal representations of modern statistical machine translation systems can be exploited for cross-language information retrieval. We tackle two core issues that are central to query translation: how to exploit context to...

Understanding Intrinsic Diversity in Web Search: Improving Whole-Session Relevance
Karthik Raman, Paul N. Bennett, Kevyn Collins-Thompson
Article No.: 20
DOI: 10.1145/2629553

Current research on Web search has focused on optimizing and evaluating single queries. However, a significant fraction of user queries are part of more complex tasks [Jones and Klinkner 2008] which span multiple queries across one or more search...

Cache Design of SSD-Based Search Engine Architectures: An Experimental Study
Jianguo Wang, Eric Lo, Man Lung Yiu, Jiancong Tong, Gang Wang, Xiaoguang Liu
Article No.: 21
DOI: 10.1145/2661629

Caching is an important optimization in search engine architectures. Existing caching techniques for search engine optimization are mostly biased towards the reduction of random accesses to disks, because random accesses are known to be much more...
