Hydra - Content Processing Framework for Search Driven Solutions
Presented at Lucene Revolution, 7-8 May in Boston and Berlin Buzzwords 4-5 June, 2012.
When working with free text search, the quality of the data in the index is a key factor on the quality of the results delivered and has a major impact on the information consumption experience. Hydra is designed to give the search solution the tools necessary to modify the data that is to be indexed in an efficient and flexible way. Providing a scalable and efficient pipeline which the documents pass through before being indexed into the search engine does this.
Introducing Hydra – An Open Source Document Processing Framework
Presented by Joel Westberg, Findwise AB - See conference video - http://www.lucidimagination.com/devzone/events/conferences/lucene-revolution-2012
This presentation will detail the document-processing framework called Hydra that has been developed by Findwise. It is intended as a description of the framework and the problem it aims to solve. We will first discuss the need for scalable document processing, outlining that there is a missing link between the open source chain to bridge the gap between source system and the search engine, then will move on to describe the design goals of Hydra, as well as how it has been implemented to meet those demands on flexibility, robustness and ease of use. This session will end by discussing some of the possibilities that this new pipeline framework can offer, such as freely seamlessly scaling up the solution during peak loads, metadata enrichment as well as proposed integration with Hadoop for Map/Reduce tasks such as page rank calculations.
Introduction to Big Data
Big data refers to large volumes of structured and unstructured data that can be analyzed to reveal patterns and trends. It is characterized by 3 Vs - volume, velocity, and variety. Hadoop and associated tools like HDFS, MapReduce, Hive and NoSQL databases are used to handle big data. These tools provide scalability, flexibility and support both structured and unstructured data. Understanding big data analytics provides opportunities in data science and IT jobs and benefits industries like banking, healthcare, manufacturing and more through real-time insights.

Indexing big data in the cloud
Amazon Web Services offers a quick and easy way to build a scalable search platform, a flexibility is especially useful when an initial data load is required but the hardware is no longer needed for day-to-day searching and adding new documents. This presentation will cover one such approach capable of enlisting hundreds of worker nodes to ingest data, track their progress, and relinquish them back to the cloud when the job is done. The data set that will be discussed is the collection of published patent grants available through Google Patents. A single Solr instance can easily handle searching the roughly 1 million patents issued between 2010 and 2005, but up to 50 worker nodes were necessary to load that data in a reasonable amount of time. Also, the same basic approach was used to make three sizes of PNG thumbnails of the patent grant TIFF images. In that case 150 worker nodes were used to generate 1.6 Tb of data over the course of three days. In this session, attendees will learn how to leverage EC2 as a scalable indexer and tricks for using XSLT on very large XML documents.
Bi on Big Data - Strata 2016 in London
There are many options for business intelligence on Hadoop and other Big Data systems. This presentation provides an overview of some of the options.
So we all have ORCID integrations, now what?
In the past year, the major groundwork has been laid for repository systems to support ORCID identifiers. DSpace, Hydra, and EPrints all have support for storing and managing ORCIDs. However, we are still in the early stages of ORCID adoption. Only a small fraction of repository content is annotated with ORCIDs, and most end-users have not yet realized any benefit from the features based on ORCID.
This panel will bring together representatives of major repository systems to relate the current status of ORCID implementations, discuss plans for future work, and identify shared goals and challenges. The panelists will discuss how ORCID support provides practical benefits both to repository staff and end-users, with a focus on features that exist now or will exist in the next year.

Integrating Drupal with a Triple Store
The document discusses integrating Drupal, an open-source content management system, with a triple store to enable semantics-driven publishing of open data at scale. Existing approaches in Drupal concentrate on embedding RDFa from its internal data model and depend on arc2, which lacks SPARQL 1.1 support and scalability. The proposed approach uses RESTful calls from Drupal to a triple store via SPARQL to access data beyond Drupal's entity model, enhancing pages. This allows Drupal to publish much larger, semantically enriched open data on topics like 200+ countries, 400-500 disciplines, and 10,000+ athletes.

It has two main components - the Hadoop Distributed File System (HDFS) for storage, and MapReduce for processing. HDFS stores data across clusters of machines with redundancy, while MapReduce splits tasks across processors and handles shuffling and sorting of data. Hadoop allows cost-effective processing of large, diverse datasets and has become a standard for big data.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
