A Similarity Reinforcement Algorithm for Heterogeneous Web Pages (2008)

Ning Liu, Jun Yan, Fengshan Bai, Benyu Zhang, Wensi Xi, Weiguo Fan, ...

Abstract. Many machine learning and data mining algorithms crucially rely on the similarity metrics. However, most early research works such as Vector Space Model or Latent Semantic Index only used...

Algorithms, Experimentation (2008)

Wensi Xi

Web communities are web virtual broadcasting spaces where people can freely discuss anything. While such communities function as discussion boards, they have even greater value as large repositories...

VT at TREC-2003: The Web Track Report (2008)

Rui Yang, Li Wang, Weiguo Fan, Wensi Xi, Ming Luo, Ye Zhou, ...

This year, we participated in the Web Track in addition to the Robust Track. We submitted results on both topic distillation and home page/named page finding tasks. As our time and human resources...

ABSTRACT Machine Learning Approach for Homepage Finding Task (2008)

Wensi Xi, Edward A. Fox

This paper describes new machine learning approaches to predict the correct homepage in response to a user’s homepage finding query. This involves two phases. In the first phase, a decision tree is...

Can We Get A Better Retrieval Function From Machine? (2008)

Li Wang, Weiguo Fan, Wensi Xi, Edward A. Fox

The quality of an information retrieval system heavily depends on its retrieval function, which returns a similarity measurement between the query and each document in the collection. Documents are...

Ranking Function Discovery by Genetic Programming for Robust Retrieval (2008)

Li Wang, Weiguo Fan, Rui Yang, Wensi Xi, Ming Luo, Ye Zhou, ...

Ranking functions are instrumental for the success of an information retrieval (search engine) system. However nearly all existing ranking functions are manually designed based on experience,...

Iterative Computing over a Unified Relationship Matrix for Information Integration (2006)

Xi, Wensi

In this dissertation I use a Unified Relationship Matrix (URM) to represent a set of heterogeneous data objects and their inter-relationships. I argue that integrated and iterative computations over...

Scalable collaborative filtering using cluster-based smoothing (2005)

Gui-rong Xue, Chenxi Lin, Qiang Yang, Wensi Xi, Hua-jun Zeng, Yong Yu, ...

Memory-based approaches for collaborative filtering identify the similarity between two users by comparing their ratings on a set of items. In the past, the memory-based approaches have been shown to...

Improving web search results using affinity graph (2005)

Benyu Zhang, Hua Li, Yi Liu, Lei Ji, Wensi Xi, Weiguo Fan, ...

In this paper, we propose a novel ranking scheme named Affinity Ranking (AR) to re-rank search results by optimizing two metrics: (1) diversity-- which indicates the variance of topics in a group of...

Simfusion: measuring similarity using unified relationship matrix (2005)

Wensi Xi, Edward A. Fox, Weiguo Fan

In this paper we use a Unified Relationship Matrix (URM) to represent a set of heterogeneous data objects (e.g., web pages, queries) and their interrelationships (e.g., hyperlinks, user clickthrough...
