Paper Title:
A Linked Data Platform for Mining Software Repositories
Paper Abstract:
The mining of software repositories involves the extraction of both basic and value-added information from existing software repositories. The repositories will be mined to extract facts by different stakeholders (e.g. researchers, managers) and for various purposes. To avoid unnecessary pre-processing and analysis steps, sharing and integration of both basic and value-added facts are needed. In this research, we introduce SeCold, an open and collaborative platform for sharing software datasets. SeCold provides the first online software ecosystem Linked Data platform that supports data extraction and on-the-fly inter-dataset integration from major version control, issue tracking, and quality evaluation systems. In its first release, the dataset contains about two billion facts, such as source code statements, software licenses, and code clones from 18 000 software projects. In its second release the SeCold project will contain additional facts mined from issue trackers and versioning systems. Our approach is based on the same fundamental principle as Wikipedia: researchers and tool developers share analysis results obtained from their tools by publishing them as part of the SeCold portal and therefore make them an integrated part of the global knowledge domain. The SeCold project is an official member of the Linked Data dataset cloud and is currently the eighth largest online dataset available on the Web.

IRJET- Generate Distributed Metadata using Blockchain Technology within HDFS ...IRJET Journal
This document proposes a new HDFS architecture that eliminates the single point of failure of the NameNode by distributing metadata storage using blockchain technology. In the traditional HDFS, the NameNode stores all metadata, but in the new architecture this is replaced by blockchain miners that securely store encrypted metadata across data nodes. Blockchain links data blocks in a serial manner with cryptographic hashes to ensure integrity. The key components are HDFS clients, data nodes for storage, and specially designated miner nodes that help create and store metadata blocks in an encrypted and distributed fashion similar to how transactions are recorded in a blockchain. This architecture aims to provide reliable, secure and faster metadata access without a single point of failure.
This document discusses evaluating FPGA acceleration for real-time unstructured search. It motivates the need for high-performance and energy-efficient data analysis due to the explosion of data. It describes using FPGAs to accelerate unstructured search workloads like document filtering and profile matching. It details the workload algorithm, hardware platform with four FPGAs, synthetic datasets used, and experimental parameters. Performance results show the FPGA acceleration provides speedups of 23X-38X and energy efficiency improvements of 31X-40X compared to optimized multi-threaded CPU implementations.
OpenSplice DDS enables seamless, timely, scalable and dependable data sharing between distributed applications and network-connected devices. Its technical and operational benefits have propelled adoption across multiple industries, such as Defence and Aerospace, SCADA, Gaming, Cloud Computing, Automotive, etc.
If you want to learn about OpenSplice DDS or discover some of its advanced features, this webcast is for you!
In this two-parts presentation we will cover most of the aspects tied to architecting and developing OpenSplice DDS systems. We will look into Quality of Services, data selectors concurrency and scalability concerns.
We will present the brand-new, and recently finalized, C++ and Java APIs for DDS, including examples of how this can be used with C++11 features. We will show how, increasingly popular, functional languages such as Scala can be used to efficiently and elegantly exploit the massive HW parallelism provided by modern multi-core processors.
Finally we will present some OpenSplice specific extensions for dealing very high-volumes of data – meaning several millions of messages per seconds.

MongoDB on Windows Azure provides two options for deploying the MongoDB database on Microsoft's cloud platform:
1) Windows Azure Virtual Machines allow more control over infrastructure but require more operational effort. Users can choose Windows or Linux and install software themselves.
2) Windows Azure Cloud Services decrease operational effort through automated management but provide less infrastructure control. Only Windows is supported and configurations are pre-defined.
Both options provide scalability and high availability through features like replication and sharding. Developers should evaluate the level of control and effort needed to determine the best deployment model for their application on the Windows Azure cloud.
This document discusses the rapid growth of digital data and the challenges of analyzing large, unstructured datasets. It notes that in just one week in 2000, the Sloan Digital Sky Survey collected more data than had been collected in all of astronomy previously. Today, the Large Hadron Collider generates 40 terabytes per second and Twitter generates over 1 terabyte of tweets daily. By 2013, annual internet traffic was predicted to reach 667 exabytes. Hadoop provides a framework to analyze these vast and diverse datasets by distributing processing across commodity clusters close to where the data is stored.
The HiTiME project aims to develop a system that can recognize entities like people, organizations, locations, dates and professions in historical text documents. The system splits documents into words, recognizes entities using named entity recognition and stores the output in a database. It also aims to integrate with other systems at the International Institute of Social History to improve search, metadata and visualization of historical data. Some planned improvements include using additional natural language processing tools, disambiguating entities, recognizing composite entities, and integrating with applications like the Basic Word Sequence Analysis tool.
The document discusses creating Linked Open Data (LOD) microthesauri from the Art & Architecture Thesaurus (AAT). It defines a microthesaurus as a designated subset of a thesaurus that can function independently. The document provides an overview of creating an AAT-based LOD dataset for a digital art and architecture collection. It also demonstrates how to extract concept URIs and labels from the AAT thesaurus structure using SPARQL queries to build microthesauri.

Jeanne Holm: Data Mining for Good - How Linked Data is Transforming CitiesSemantic Web Company
Data mining techniques can be used for social good by empowering people through open data. For example, in Kampala traffic data was analyzed to identify unsafe intersections and reduce accidents, while in Washington D.C. open utility data helped lower household bills. Overall, releasing and using open data for development initiatives supports achieving UN Sustainable Development Goals by empowering people to make better decisions through increased transparency and civic participation.
Mining the Web of Linked Data with RapidMinerHeiko Paulheim
Lots of data from different domains is published as Linked Open Data. While there are quite a few browsers for that data, as well as intelligent tools for particular purposes, a versatile tool for deriving additional knowledge by mining the Web of Linked Data is still missing. In this challenge entry, we introduce the RapidMiner Linked Open Data extension. The extension hooks into the powerful data mining platform RapidMiner, and offers operators for accessing Linked Open Data in RapidMiner, allowing for using it in sophisticated data analysis workflows without the need to know SPARQL or RDF. As an example, we show how statistical data on scientific publications, published as an RDF data cube, can be linked to further datasets and analyzed using additional background knowledge from various LOD datasets.
An introduction to Semantic Web and Linked DataFabien Gandon
Here are the steps to answer this SPARQL query against the given RDF base:
1. The query asks for all ?name values where there is a triple with predicate "name" and another triple with the same subject and predicate "email".
2. In the base, _:b is the only resource that has both a "name" and "email" triple.
3. _:b has the name "Thomas".
Therefore, the only result of the query is ?name = "Thomas".
So the result of the SPARQL query is:
?name
"Thomas"
The document discusses data mesh vs data fabric architectures. It defines data mesh as a decentralized data processing architecture with microservices and event-driven integration of enterprise data assets across multi-cloud environments. The key aspects of data mesh are that it is decentralized, processes data at the edge, uses immutable event logs and streams for integration, and can move all types of data reliably. The document then provides an overview of how data mesh architectures have evolved from hub-and-spoke models to more distributed designs using techniques like kappa architecture and describes some use cases for event streaming and complex event processing.

L’architettura di Classe Enterprise di Nuova GenerazioneMongoDB
This document discusses using MongoDB as part of an enterprise data management architecture. It begins by describing the rise of data lakes to manage growing and diverse data volumes. Traditional EDWs struggle with this new data variety and volume. The document then provides an overview of MongoDB's features like flexible schemas, secondary indexes, and aggregation capabilities that make it suitable for building different layers of an EDM pipeline for tasks like raw data storage, transformation, analysis, and serving data to downstream systems. Example use cases are presented for building a single customer view and for replacing Oracle with MongoDB.
This document provides an overview of data mining. It defines data mining as extracting meaningful information from large data sets. It describes the typical data mining process, which includes problem definition, data gathering/preparation, model building/evaluation, and knowledge deployment. It also outlines several common data mining techniques like neural networks, clustering, decision trees, and support vector machines. Finally, it discusses applications of data mining in business, science, security, marketing, and spatial data analysis.
This document discusses Big Data and provides definitions and examples. It defines Big Data as very large and loosely structured data sets that are difficult to process using traditional database and software techniques. Examples of Big Data sources include social networks and machine-to-machine data. The document also discusses Hadoop and NoSQL databases as tools for managing and analyzing Big Data, and provides examples of companies using these technologies.
The document discusses the emergence of big data and new data architectures needed to handle large, diverse datasets. It notes that internet companies built their own data systems like Hadoop to process massive amounts of unstructured data across thousands of servers in a fault-tolerant, scalable way. These systems use a map-reduce programming model and distributed file systems like HDFS to store and process data in a parallel, distributed manner.
Almost all developers face the challenge of reactively debugging failed business transaction processes. Not only does this require extensive navigation of enormous volumes of log data, but determining root cause becomes a laborious and time-consuming task.
Additionally, business managers often request developers and operations to provide analytics on applications, resulting in the tedious task of charting the information, most usually from intangible data. Learn how to capture, extract and analyze your event data by having analytics embedded in the application. Download the white-paper that details how to gain Application Intelligence through effective logging.

The document proposes a distributed deep learning framework for big data applications built on Apache Spark. It discusses challenges in distributed computing and deep learning in big data. The proposed system addresses issues like concurrency, asynchrony, parallelism through a master-worker architecture with data and model parallelism. Experiments on sentiment analysis using word embeddings and deep networks on a 10-node Spark cluster show improved performance with increased nodes.
Spark Based Distributed Deep Learning Framework For Big Data Applications Humoyun Ahmedov
Deep Learning architectures, such as deep neural networks, are currently the hottest emerging areas of data science, especially in Big Data. Deep Learning could be effectively exploited to address some major issues of Big Data, such as fast information retrieval, data classification, semantic indexing and so on. In this work, we designed and implemented a framework to train deep neural networks using Spark, fast and general data flow engine for large scale data processing, which can utilize cluster computing to train large scale deep networks. Training Deep Learning models requires extensive data and computation. Our proposed framework can accelerate the training time by distributing the model replicas, via stochastic gradient descent, among cluster nodes for data resided on HDFS.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.
