Dec 17, 2017· Abstract A significant portion of biomedical literature is represented in a manner that makes it difficult for consumers to find or aggregate content through a computational query. One approach to facilitate reuse of the scientific literature is to structure this information as linked data using standardized web technologies.


Abstract Peer-to-peer databases are becoming prevalent on the Internet for distribution and sharing of documents, applications, and other digital media. The problem of answering large scale, ad-hoc analysis queries – e.g., aggregation queries – on these databases poses unique challenges. Exact solutions can be time consuming and


ABSTRACT. In this paper, we propose a framework called CQ-Buddy, for supporting distributed continuous query (CQ) processing system based on Peer-to-Peer (P2P) technology. Working on the basis of peer heterogeneity, peers in a CQ-Buddy network "help" one another by sharing query workload and providing data.

ABSTRACT A peer-to-peer (P2P) is a distributed application architecture, where each computer (node) in the net acts as a client/ server for the other nodes in the network. It allows sharing right to different sources and partitions tasks or workloads among peers. All the peers are equally privileged participants in the application.


range. Queries can be specified for data items, chunks and metadata. The retrieval of them follows similar query-response mechanisms, to be presented in Section III and IV. III. PEER DATA DISCOVERY (PDD) Peer Data Sharing (PDS) consists of two components: Peer Data Discovery (PDD) and Peer Data Retrieval (PDR).


Sci-Hadoop executes queries as map/reduce programs defined over the logical data model. We describe the implementation of a Sci-Hadoop prototype for NetCDF data sets and quantify the performance of five separate optimizations that address the following goals for several representative aggregate queries: reduce total data transfers, reduce ...

The method used for calculating this type of criteria is very different from that of existing criteria, and this can have a notable effect on the processing of ordinary skyline path queries. This paper defines the aggregate attributes of paths, discusses the impact of aggregate attributes on skyline path queries, and proposes a novel index tree ...


query processing has been also studied in peer-to-peer environments. The KLEE system (Michel et al. [2]) addressed this problem, where distributed aggregation queries are processed based on index lists located at isolated sites. KLEE assumes no random accesses are made to index lists located at each peer.

upper layer is a peer-2-peer (P2P) network. Each peer node acts as a gateway to the lower sensor nodes layer, and the gateways are connected to the Internet or Intranet for remote data access. Sensor nodes continuously sense data from the physical world. After simple processing of these measurements on the on-board processor, meaningful data is

IJCSE Abstract

Jul 15, 2021· Hence, Approximate Query Processing Techniques (AQPTs) are an attractive option. AQPT are ideally suited for executing aggregate queries, where the AQPT provides approximate results with attractive computational efficiency. Recently in the literature, AQPT was presented to execute simple non-join aggregate queries on Big Data.

network, nodes spend processing resources (i.e., cycles) to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are there-fore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate (i.e., overall the ...


Abstract. In this demonstration, we present BlinkDB, a massively parallel, sampling-based approximate query processing framework for running interactive queries on large volumes of data. The key observation in BlinkDB is that one can make reasonable decisions in the absence of perfect answers. ... BlinkDB extends the Hive/HDFS stack and can ...

Abstract. An aggregate nearest neighbor (ANN) query returns a point of interest (POI) that minimizes an aggregate function for multiple query points. In this paper, we propose an efficient approach to tackle ANN queries in road networks. Our approach consists of two phases: searching phase and pruning phase. In particular, we first continuously ...
