The document discusses testing the use of the SERONTO ontology for semantic data integration of distributed ecological databases from ALTER-Net and LTER Europe. Five databases were independently mapped to SERONTO concepts and queries could be run across the integrated data without knowledge of the underlying database structures. However, the effort required for mapping was significant and maintaining reference lists will be crucial. More use cases are needed to fully evaluate SERONTO's potential for LTER data integration.

"On chemical structures, substances, nanomaterials and measurements"
Nina Jeliazkova, Ideaconsult
This talk attempts to highlight how I came to recognize the fundamental role of measurements, coming from the realm of data modelling and data analysis. Besides retaining the data provenance it provides insights how do we go beyond chemical structures and address the challenges of representing the identity of chemical substances and nanomaterials (with examples from the latest developments of AMBIT web services and OpenTox API). Finally, supporting the vision of distributed, open, web-like approach towards recording subtle experimental details is essential, not only for the chemists and biologists in the labs, but for all of us using, modelling, storing and querying the data.

AnIML: A New Analytical Data Standard
Started in 2004 (under ASTM Committee E13.15) the Analytical Information Markup Language (AnIML) is an XML based standard for capturing, sharing, viewing, and archiving analytical instrument data from any analytical technique.
This paper discusses the AnIML standard in terms of philosophy, structure, usage, and the resources available to work with the standard. Examples will be given for different techniques as well as strategies for migration of legacy data. Finally, the current status of the standard and time frame for promulgation through ASTM will be reported.
Overview of the Analytical Information Markup Language (AnIML)
This document provides an overview of the Analytical Information Markup Language (AnIML), which is an XML standard for storing analytical instrumentation data. It discusses the goals of AnIML, including being extensible, flexible, and human-readable. The document outlines the sections of an AnIML file and how AnIML defines techniques. It also covers using AnIML for publishing, referencing, and performing calculations on instrumentation data. Future developments mentioned include finalizing the AnIML 1.0 specification and creating additional technique definitions.

This document discusses efforts to standardize data templates for the Human Immunology Project Consortium (HIPC) to make HIPC data more findable, accessible, interoperable, and reusable (FAIR). Currently, HIPC data is inconsistently formatted and named. The authors propose mapping HIPC data submission templates to ontologies to semantically normalize the data and facilitate data integration and querying. They have mapped template elements like assay types and value sets to ontologies like the Ontology for Biomedical Investigations and are working with ontology groups to refine and improve the mappings. The goal is to incorporate this ontology-linked metadata approach into the CEDAR and ImmPort databases.

Benchmarking Versioning for Big Linked Data
The document discusses benchmarking versioning systems for big linked data. It describes the need for versioning benchmarks that test how systems perform with respect to storage space required for multiversion repositories and efficiency of retrieving different versions and answering cross-snapshot queries. It outlines approaches for versioning like full materialization, delta-based, and timestamped tuples. The document also lists several linked data stores with versioning capabilities and notes the complete lack of existing versioning benchmarks. It proposes the design of a versioning benchmark for the HOBBIT project that would generate versions based on changes observed in evolving datasets and include cross-snapshot queries to evaluate system performance.

Abstract. The development of open data requires a better reusability of data. Indeed, the catalogs listing data dispersed in different countries have a crucial role. However, the degree of openness is also a key success factor for open data. In this paper, we study the PublicData.eu catalogue, which allows accessing open datasets from European countries and analyse the metadata recorded for each dataset. The objectives are to (i) identify the quality of a sample of metadata properties, which are critical to enable data reuse and to (ii) study the stated level of data openness. The study uses the Tim Berners-Lee’s five star evaluation scale.
Holistic Benchmarking of Big Linked Data: HOBBIT
The document discusses the HOBBIT project, which aims to provide holistic benchmarking of big linked data technologies. It notes the large volumes of linked data and number of available technologies. HOBBIT will identify key performance indicators and benchmarks for critical steps in the linked data lifecycle, including generation, analysis, storage, and visualization. It will gather industry performance needs and provide a platform for standardized benchmarking and challenges to compare technology performance. The project is coordinated by researchers in Europe and runs for three years under the Horizon 2020 program.

Geant4 Model Testing Framework: From PAW to ROOT
Roman Atachiants developed a framework to test Geant4 models that translates macros from PAW (Physics Analysis Workstation) to ROOT. The framework builds a unified database for model testing and allows comparing data points from experiments to simulation curves. It includes ROOT libraries, Geant4 test programs, and helpers for simulation, analysis, and plotting. The port from PAW to ROOT provides more comprehensive statistical analysis capabilities and allows obtaining better comparison results with larger statistics.
Standards and tools for model management in biomedical research
Slides from the presentation at IDAMO 2016, Rostock. May 2016.
Most scientific discoveries rely on previous or other findings. A lack of transparency and openness led to what many consider the "reproducibility crisis" in systems biology and systems medicine. The crisis arose from missing standards and inappropriate support of
standards in software tools. As a consequence, numerous results in low-and high-profile publications cannot be reproduced.
In my presentation, I summarise key challenges of reproducibility in systems biology and systems medicine, and I demonstrate available solutions to the related problems.

Poster Semantic data integration proof of concept
This document summarizes a proof of concept study that tested the ability to semantically integrate ecological data from different databases using the Socio-Ecological Research and Observation oNTOlogy (SERONTO). The study showed that SERONTO could successfully import database schemas and reference lists, map relations between database tables and SERONTO concepts, and allow complex queries across multiple connected databases from within SERONTO. However, maintaining mappings between reference lists and coupling value sets, units and calculations requires further work. Overall, the study demonstrated the feasibility of using SERONTO and semantic approaches to provide integrated access to distributed ecological data.

Seronto Process
1) ALTER-NET is a network for long-term ecological research that needed to integrate data from many sources using SERONTO, a semantic framework and socio-ecological research ontology.
2) SERONTO includes a core ontology and domain ontologies for ecosystems, biodiversity, and socio-economics. It provides a common model for structuring ecological observations for data management.
3) Developing the ontologies required roles like working groups, experts, and a coordinator to create examples, document issues, and refine the process over time through workshops and a wiki decision forum. Clear coordination and documentation were essential.
Semantic Data Integration of Biodiversity Data with the SERONTO Ontology
The document discusses using the SERONTO ontology to semantically integrate three biodiversity datasets. SERONTO was developed by the ALTER-Net Network of Excellence to allow interoperability across heterogeneous data resources from multiple institutions and scientific domains. The project aims to integrate the National Biodiversity Network Gateway, Countryside Survey, and Environmental Change Network datasets using SERONTO. This will create a distributed system that can be extended to integrate other biodiversity data, demonstrating SERONTO's ability to integrate biodiversity data at different scales.
Seronto Domain Ontology Framework
SERONTO is an ontology framework consisting of a core ontology and multiple domain ontologies that integrate with the core ontology. The document discusses the structure of SERONTO, including the core ontology, domain ontologies, and integration layers between them. It also addresses developing domain ontologies consistently within the SERONTO framework through an iterative process involving domain experts and the wider community.

Infosys Ltd: Performance Tuning - A Key to Successful Cassandra Migration
In last few years, technology has seen a major drift in the dominance of traditional / RDMBS databases across different domains. Expeditious adoption of NoSQL databases especially Cassandra in the industry opens up a lot more discussions on what are the major challenges that are faced during implementation of Cassandra and how to mitigate it. Many a times we conclude that migration or POC (proof of concept) is not successful; however the real flaw might be in the data modeling, identifying the right hardware configurations, database parameters, right consistency level and so on. There's no one good model or configuration which fits all use cases and all applications. Performance tuning an application is truly an art and requires perseverance. This paper delve into different performance tuning considerations and anti-patterns that need to be considered during Cassandra migration / implementation to make sure we are able to reap the benefits of Cassandra, what makes it a ‘Visionary’ in 2014 Gartner’s Magic Quadrant for Operational Database Management Systems.

The operationalization required considerations for scalability, maintaining a single codebase for analysis and production, code protection, logging, exception handling, and providing an analysis GUI. Solutions like using foreach for parallelization in R, embedding and obfuscating R code in .NET, and connecting multiple RServe processes were proposed to meet integration and non-functional requirements.

Presenting a Technical Proof of Concept to Customers
This document summarizes keynote monitoring of a demo server over two days. It measured response times and availability from 5 US locations every 30 minutes, and internally every 5 minutes. There were two load tests run against the server that decreased availability and increased response times, particularly for the home page. The internal measurements showed specific steps like the about page being impacted. Overall, the monitoring identified performance issues during the load tests and provided detailed response time data down to the page level.
Cloud Migration
This document outlines a phased approach to migrating applications to AWS cloud. The six phases include: 1) cloud assessment, 2) proof of concept, 3) data migration, 4) application migration, 5) leveraging cloud technologies, and 6) optimization. Each phase has specific goals and activities such as assessing applications for cloud readiness, building pilots to validate technical solutions, migrating data storage, deploying applications on AWS, automating processes, and optimizing usage to reduce costs.
Proof of Concept for Hadoop: storage and analytics of electrical time-series
1. EDF conducted a proof of concept to store and analyze massive time-series data from smart meters using Hadoop.
2. The proof of concept involved storing over 1 billion records per day from 35 million smart meters and running analytics queries.
3. Results showed Hadoop could handle tactical queries with low latency and complex analytical queries within acceptable timeframes. Hadoop provides a low-cost solution for massive time-series storage and analysis.
How to Build a Proof of Concept
A proof of concept (POC) involves building a simple version of a product idea to test it with users before fully developing it. A POC should be completed in 1-4 weeks with a small team and focus on core functionality rather than polish. Usability testing the POC with real users provides critical feedback on whether the idea is worth pursuing further. For example, a POC for a stock trading app may include basic login, search, portfolio views, and simulated trading recommendations to get early feedback from potential users.
Big Data Proof of Concept
RCG proposes a Big Data Proof of Concept (PoC) to demonstrate the business value of analyzing a client's data using Big Data technologies. The PoC involves:
1) Defining a business problem and objectives in a workshop with client.
2) The client collecting and anonymizing relevant data.
3) RCG loading the data into their Big Data lab and analyzing it using Big Data technologies.
4) RCG producing results, insights, and recommendations for applying Big Data and taking business actions.
The PoC requires no investment from the client and provides an opportunity to explore Big Data analytics without committing resources.

From allotrope to reference master data management
We will present the updated Allotrope framework and cover .adf files and how they are used. We’ll demonstrate semantic modeling in .adf (OWL models + the SHACL constraint language). We’ll show how the data description layer in .adf can be extended via a “semantic hub” that we call Reference Master Data Management, which can be used across the enterprise. RMDM provides a means to integrate metadata about any data source within your enterprise – including structured, semi-structured and unstructured data. Customer examples from current project work will be given where possible. Last we’ll show scalability of this approach using data science techniques can be employed beyond just the metadata – we refer to this as Big Analysis.
Geospatial metadata and spatial data workshop: 19 June 2014
Overview of the world of geospatial metadata, and the role of the EDINA service GoGeo in creating, saving, and discovering it. Presented on 19 June 2014 by Tony Mathys in Aberdeen, Scotland.
Revolutionizing Laboratory Instrument Data for the Pharmaceutical Industry:...
The Allotrope Foundation is a consortium of major pharmaceutical companies and a partner network whose goal is to address challenges in the pharmaceutical industry by providing a set of public, non-proprietary standards for using and integrating analytical laboratory data. Current challenges in data management within the pharmaceutical industry often center around inconsistent or incomplete data and metadata and proprietary data formats. Because of a lack of standardization, several operations (e.g. integration of instruments/applications, transfer of methods or results, archiving for regulatory purposes) require unnecessary efforts. Further, higher level aggregation of data, e.g. regulatory filings, that are derived from multiple sources of laboratory data are costly to create. These unnecessary costs impact operations within a company’s laboratories, between partnering companies, and between a company and contract research organizations (CROs). Finally, the accelerating transition of laboratories from hybrid (paper + electronic) to purely electronic data streams, coupled with an ever-increasing regulatory scrutiny of electronic data management practices, further require a comprehensive solution. This talk will discuss how The Allotrope Foundation is providing a new framework for data standards through collaboration between numerous stakeholders.
Next-Generation Search Engines for Information Retrieval
In the recent years, there have been significant advancements in the areas of scientific data management and retrieval techniques, particularly in terms of standards and protocols for archiving data and metadata. Scientific data is generally rich, not easy to understand, and spread across different places. In order to integrate these pieces together, a data archive and associated metadata should be generated. This data should be stored in a format that can be locatable, retrievable and understandable, more importantly it should be in a form that will continue to be accessible as technology changes, such as XML. New search technologies are being implemented around these protocols, which makes searching easy, fast and yet robust. One such system, Mercury, a metadata harvesting, data discovery, and access system, built for researchers to search to, share and obtain spatiotemporal data used across a range of climate and ecological sciences.
Investigating plant systems using data integration and network analysis
The document discusses challenges in integrating plant data from multiple sources and proposes solutions. It notes that plant data is sparse, distributed across many databases in various formats, and focused primarily on the model plant Arabidopsis. Data integration is necessary to address key biological questions by consolidating information from pathway databases, gene annotations, protein interactions, and more. The document outlines approaches to data integration including controlled vocabularies, ontologies, data standards, and integration applications specifically designed to combine data sources like Ondex. Effective integration is important to fully leverage available plant data.
OSFair2017 Workshop | EPOS: European Plate Observing System

A Software Infrastructure for Multidimensional Data Analysis: A Data Modellin...IJCSIS Research Publications
Rapid changes in the technology lead to increased variety of data sources. These varied data sources
generating data in the large volume and with extremely high speed. To accommodate and use this data in decision
making systems is the big challenge. To make fullest use of the valuable data generated by different systems, target
users of the analysis systems need to be increased. In general knowledge discovery process using the tools which are
available requires the handsome expertise in the domain as well as in the technology. The project ITDA (Integrated
Tool for Data Analysis) focuses to provide the complete platform for multidimensional data analysis to enhance the
decision making process in every domain. This projects provides all the techniques required to perform
multidimensional data analysis and avoids the overheads occurred by the traditional cube architecture followed by
most of the analytics system. Modelling the available data in the multidimensional form is the basis and crucial step
for multidimensional analysis. This work describes the multidimensional modelling aspect and its implementation

Constructing ontologies from relational databases is an active research topic in the Semantic Web domain.
While conceptual mapping rules/principles of relational databases and ontology structures are being
proposed, several software modules or plug-ins are being developed to enable the automatic conversion of
relational databases into ontologies. However, the correlation between the resulting ontologies built
automatically with plug-ins from relational databases and the database-toontology mapping principles has
been given little attention. This study reviews and applies two Protégé plug-ins, namely, DataMaster and
OntoBase to automatically construct ontologies from a relational database. The resulting ontologies are
further analysed to match their structures against the database-to-ontology mapping principles. A
comparative analysis of the matching results reveals that OntoBase outperforms DataMaster in applying
the database-to-ontology mapping principles for automatically converting relational databases into
ontologies
Fairification experience clarifying the semantics of data matrices

IRJET - Voice based Natural Language Query Processing
This document describes a voice-based natural language query processing system that allows non-expert users to interact with a database using natural language queries. The system takes a user's spoken query as input, converts it to text using speech recognition, analyzes the text to generate a SQL query, executes the SQL query against the database, and displays the results in a table. The system addresses challenges like ambiguity through techniques such as tokenization, lexical analysis, syntactic analysis, and semantic analysis to map the natural language query to a valid SQL query.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
