    Nowadays, huge volumes of data, including scientific data, are organized or exported in tree-structured form. Querying capabilities are provided through tree-pattern queries. The need for integrating multiple data sources with different tree structures has driven, recently, the suggestion of query languages that relax the complete specification of a tree pattern. In this paper we adopt a query lan... View full abstract»

    XML has become the standard for data exchange for a wide variety of applications, particularly in the scientific community. In order to efficiently process queries on XML representations of scientific data, we require specialized techniques for evaluating XPath expressions. Exploiting materialized views in query processing significantly enhances query processing performance. We propose a novel vie... View full abstract»

  • The Holodex: Integrating Summarization with the Index

    Publication Year: 2006 , Page(s): 23 - 32

    In this paper we introduce the Holodex, a `holistic index' for databases that includes a facility for statistics and aggregate-like computations. The Holodex is an integration of the conventional index and summarization over traversals of the index. It can store customized summaries in its data structure, and in this way it can maintain, and provide fast access to, summarized information. The Holo... View full abstract»

  • Minimizing I/O Costs of Multi-Dimensional Queries with Bitmap Indices

    Publication Year: 2006 , Page(s): 33 - 44

    Bitmap indices have been widely used in scientific applications and commercial systems for processing complex, multi-dimensional queries where traditional tree-based indices would not work efficiently. A common approach for reducing the size of a bitmap index for high cardinality attributes is to group ranges of values of an attribute into bins and then build a bitmap for each bin rather than a bi...

    This paper investigates data-preservation, a feature of scientific workflow middleware (SWM) useful for supporting data provenance and "smart recomputation." We observe that in order for an SWM supporting data preservation to achieve decent performance, it should execute on top of copy-on-write file systems. Unfortunately, most file systems in-use at scientific computing facilities were designed w... View full abstract»

    Many publish/subscribe systems have been built using wireless sensor networks, WSNs, deployed for real-world environmental data collection, security monitoring, and object tracking. However, research efforts on WSN-based publish/subscribe systems have largely focused on routing algorithms leaving data management issues mostly untouched. This paper considers a publish/subscribe system built on top ... View full abstract»

    Genealogy information is becoming increasingly abundant in light of modern genetics and the study of diseases and risk factors. As the volume of this structured pedigree data expands, there is a pressing need for better ways to manage, store, and efficiently query this data. Building on recent advances in semi-structured data management and proven relational database technology, we propose a gener... View full abstract»

    Biological Web data sources have now become essential information sources for researchers. However, their use is tedious, labor-intensive, repetitive, and possibly involve the integration of data from multiple Web data sources. In this paper, as a first step towards the full integration of Web data sources, we propose a framework that allows an integrated use of biological sources in a task-orient... View full abstract»

    A phenomenon appears in a sensor network when a group of sensors persist to generate similar behavior over a period of time. PhenomenaBases (or databases of phenomena) are equipped with phenomena detection and tracking (PDT) techniques that continuously run in the background of a sensor database system to detect new phenomena and to track already existing phenomena. The process of phenomena detect... View full abstract»

    Recent research in biology has discovered that a large portion of genes that are responsible for core biological functions are conserved in most or all living cells. This has initiated development of, and emphasizes the importance of, common annotation facilities for biological knowledge, as features and functions of an unknown gene can be related to or inferred from those of a similar and well-st...

  • Mining Frequent 3D Sequential Patterns

    We propose a mining approach, MSP, to find the maximal sequential 3D patterns with the constraints of minimum support and minimum confidence. Each pattern is a group of similar sequential 3D objects appearing in a given dataset. Mining sequential patterns in terms of 3D coordinates is important and meaningful in many real-life applications. MSP finds out the maximal patterns in terms of both lengt... View full abstract»

    The detection of correlations between different features in high dimensional data sets is a very important data mining task. These correlations can be arbitrarily complex: one or more features might be correlated with several other features, and both noise features as well as the actual dependencies may be different for different clusters. Therefore, each cluster contains points that are located o... View full abstract»

    Currently, phylogenetic tree techniques are being used in multiple areas, from tree of life problems to pathogen recognition to drug discovery. With all of these applications for phylogenetic tree techniques, methods are needed to exploit the knowledge modeled in phylogenetic trees more thoroughly. One such information point of interest is the behavior of frequent patterns in phylogenetic trees. W... View full abstract»

    Signaling pathways are chains of interacting proteins, through which the cell converts a (usually) extracellular signal into a biological response. The number of known signaling pathways in the biological literature and on the Web has been increasing at a very high rate, thus demanding a need for efficient ways of storing, visualizing, querying, and mining signaling pathways. In this paper, first ... View full abstract»

    Large scale scientific data is often stored in scientific data formats such as FITS, netCDF and HDF. These storage formats are of particular interest to the scientific user community since they provide multi-dimensional storage and retrieval. However, one of the drawbacks of these storage formats is that they do not support semantic indexing which is important for interactive data analysis where s... View full abstract»
