  • Shang, Haichuan; Lin, Xuemin; Zhang, Ying; Yu, Jeffrey; Wang, Wei (ACM, 2010)
    Substructure similarity search is to retrieve graphs that approximately contain a given query graph. It has many applications, e.g., detecting similar functions among chemical compounds. The problem is challenging as even ...
  • Wang, Wei; Xiao, Chuan; Lin, Xuemin; Zhang, Chengqi (ACM, 2009)
    Named entity recognition aims at extracting named entities from unstructured text. A recent trend of named entity recognition is finding approximate matches in the text with respect to a large dictionary of known entities, ...
  • Wang, Wei; Elliot, Steve; Williams, Mary-Anne (AIS Electronic Library (AISeL), 2010)
    More than 9.5 million people die in the developing world unnecessarily each year due not to a lack of medicine but due to poor information management. It is proposed that the IS Discipline could contribute to resolving ...
  • Cheema, Muhammad; Lin, Xuemin; Zhang, Ying; Wang, Wei; Zhang, Wenjie (ACM, 2009)
    In this paper, we study the problem of continuous monitoring of reverse k nearest neighbor queries. Existing continuous reverse nearest neighbor monitoring techniques are sensitive towards objects and queries movement. For ...
  • Zhu, Ke; Zhang, Ying; Lin, Xuemin; Zhu, Gaoping; Wang, Wei (Springer, 2010)
    Considerable efforts have been spent in studying subgraph problem. Traditional subgraph containment query is to retrieve all database graphs which contain the query graph g. A variation to that is to find all occurrences ...
  • Zhang, Wenjie; Lin, Xuemin; Zhang, Ying; Wang, Wei; Zhu, Gaoping; Yu, Jeffrey (Elsevier, 2013)
    Skyline computation has many applications including multi-criteria decision making. In this paper, we study the problem of efficiently computing the skyline over sliding windows on uncertain data elements against probability ...
  • Zhang, Wenjie; Lin, Xuemin; Zhang, Ying; Wang, Wei; Yu, Jeffrey (IEEE, 2009)
    Skyline computation has many applications including multi-criteria decision making. In this paper, we study the problem of efficient processing of continuous skyline queries over sliding windows on uncertain data elements ...
  • Zhang, Wenjie; Lin, Xuemin; Cheema, Muhammad; Zhang, Ying; Wang, Wei (IEEE, 2010)
    K Nearest Neighbor search has many applications including data mining, multi-media, image processing, and monitoring moving objects. In this paper, we study the problem of KNN over multi-valued objects. We aim to provide ...
  • Zhang, Wenjie; Lin, Xuemin; Zhang, Ying; Pei, Jian; Wang, Wei (Springer, 2010)
    Recently, due to intrinsic characteristics in many underlying data sets, a number of probabilistic queries on uncertain data have been investigated. Top-k dominating queries are very important in many applications including ...
