The Semantic Knowledge Graph

Trey Grainger

Presentation of the Semantic Knowledge Graph research paper at the 2016 IEEE 3rd International Conference on Data Science and Advanced Analytics (Montreal, Canada - October 18th, 2016) Abstract—This paper describes a new kind of knowledge representation and mining system which we are calling the Semantic Knowledge Graph. At its heart, the Semantic Knowledge Graph leverages an inverted index, along with a complementary uninverted index, to represent nodes (terms) and edges (the documents within intersecting postings lists for multiple terms/nodes). This provides a layer of indirection between each pair of nodes and their corresponding edge, enabling edges to materialize dynamically from underlying corpus statistics. As a result, any combination of nodes can have edges to any other nodes materialize and be scored to reveal latent relationships between the nodes. This provides numerous benefits: the knowledge graph can be built automatically from a real-world corpus of data, new nodes - along with their combined edges - can be instantly materialized from any arbitrary combination of preexisting nodes (using set operations), and a full model of the semantic relationships between all entities within a domain can be represented and dynamically traversed using a highly compact representation of the graph. Such a system has widespread applications in areas as diverse as knowledge modeling and reasoning, natural language processing, anomaly detection, data cleansing, semantic search, analytics, data classification, root cause analysis, and recommendations systems. The main contribution of this paper is the introduction of a novel system - the Semantic Knowledge Graph - which is able to dynamically discover and score interesting relationships between any arbitrary combination of entities (words, phrases, or extracted concepts) through dynamically materializing nodes and edges from a compact graphical representation built automatically from a corpus of data representative of a knowledge domain.

Data Modeling with NGSI, NGSI-LD

Fernando Lopez Aguilar

NGSI-LD provides a more complex data model than NGSIv2 by introducing properties, relationships, and additional metadata. It evolves NGSIv2 to support linked data by making payloads valid JSON-LD. This allows for a navigable knowledge graph compared to the simpler NGSIv2 model. The document discusses the differences between the two models and provides examples of creating and reading entity data in each.

Working With a Real-World Dataset in Neo4j: Import and Modeling

Neo4j

This webinar will cover how to work with a real world dataset in Neo4j, with a focus on how to build a graph from an existing dataset (in this case a series of JSON files). We will explore how to performantly import the data into Neo4j - both in the case of an initial import and scaling writes for your graph application. We will demonstrate different approaches for data import (neo4j-import, LOAD CSV, and using the official Neo4j drivers), and discuss when it makes to use each import technique. If you've ever asked these questions, then this webinar is for you! - How do I design a property graph model for my domain? - How do I use the official Neo4j drivers? - How can I deal with concurrent writes to Neo4j? - How can I import JSON into Neo4j?

JSON-LD and SHACL for Knowledge Graphs

Franz Inc. - AllegroGraph

Enterprise systems are increasingly complex, often requiring data and software components to be accessed and maintained by different company departments. This complexity often becomes an organization’s biggest challenge as changing data fields and adding new applications rapidly grow to meet business demands for increased customer insights. These slides are from a Webinar discussing how using SHACL and JSON-LD with AllegroGraph helps our customers simplify the complexity of enterprise systems through the ability to loosely combine independent elements, while allowing the overall system to function smoothly. In this Webinar we will demonstrate how AllegroGraph’s SHACL validation engine confirms whether JSON-LD data is conforming to the desired requirements. We will describe how SHACL provides a way for a Data Graph to specify the Shapes Graph that should be used for validation and describes how a given shape is linked to targets in the data.

MongoDB Aggregation Framework

Caserta

These are slides from our Big Data Warehouse Meetup in April. We talked about NoSQL databases: What they are, how they’re used and where they fit in existing enterprise data ecosystems. Mike O’Brian from 10gen, introduced the syntax and usage patterns for a new aggregation system in MongoDB and give some demonstrations of aggregation using the new system. The new MongoDB aggregation framework makes it simple to do tasks such as counting, averaging, and finding minima or maxima while grouping by keys in a collection, complementing MongoDB’s built-in map/reduce capabilities. For more information, visit our website at http://casertaconcepts.com/ or email us at info@casertaconcepts.com.

Attacking thru HTTP Host header

Sergey Belov

This document discusses exploiting vulnerabilities related to HTTP host header tampering. It notes that tampering with the host header can lead to issues like password reset poisoning, cache poisoning, and cross-site scripting. It provides examples of how normal host header usage can be tampered with, including by spoofing the header to direct traffic to malicious sites. The document also lists some potential victims of host header attacks, like Drupal, Django and Joomla, and recommends developers check settings to restrict allowed hosts. It proposes methods for bruteforcing subdomains and host headers to find vulnerabilities.

Sling models by Justin Edelson

AEM HUB

This document discusses Sling Models, which provide a simplified way to adapt Sling resources into domain objects in AEM. Some key points: - Sling Models allow resources to be adapted to POJOs with minimal code using annotations like @Model and @Inject. This is cleaner than previous "adapter factory" approaches. - Common use cases like injecting resource properties, child resources, services and more are supported out of the box via standard injectors. - Sling Models are pluggable, so custom injectors can be added to inject non-standard dependencies. - They allow resources and requests to be adapted to either classes or interfaces, keeping domain objects simple POJOs.

Based on the upcoming O'Reilly book "RESTful Web APIs" by Leonard Richardson and Mike Amundsen, this 1/2 day workshop covers the basics of Fielding's REST style, HTTP standards, and common practices for APIs for Web. Key topics such as how how use hypermedia to increase API flexibility and how application profiles can improve API interoperability are also covered. In addition, a wide range of existing message formats and semantic vocabularies are reviewed along with a procedure for selecting and applying these existing standards to your own implementations. Other subjects will be covered such as caching, versioning, and supporting RESTful APIs on protocols other an HTTP.Throughout the workshop, attendees will be able to apply step-by-step guidance on how to create their own RESTful Web API and share these designs with the group at the end of the session.

Making Java REST with JAX-RS 2.0

Dmytro Chyzhykov

The document discusses REST and JAX-RS 2.0. It defines REST as an architectural style for building lightweight web services using HTTP. The key REST principles include giving everything a unique ID, linking resources together, using standard HTTP methods, supporting multiple representations, communicating statelessly, and enabling caching. JAX-RS 2.0 is a Java specification that makes it easy to build RESTful web services by using annotations to define resources and HTTP methods. It supports the REST principles and features like content negotiation, hypermedia links, and caching controls.

Codemotion

We live in a interconnected world, were every day new devices, systems, and applications are connected to share information or interact between them. Thus, the importance of designing systems prepared to offer their services and data to a wide range of customers, that could discover, navigate and use their API in a standard and easy way to be consumed. But designing a headless platform to be used easily through their services is not straightforward. In this talk we will go over the challenges that we've found in adding headless nature to our platform and the foundations and tools that we have

Spark and MongoDB

Norberto Leite

Modern architectures are moving away from a "one size fits all" approach. We are well aware that we need to use the best tools for the job. Given the large selection of options available today, chances are that you will end up managing data in MongoDB for your operational workload and with Spark for your high speed data processing needs. Description: When we model documents or data structures there are some key aspects that need to be examined not only for functional and architectural purposes but also to take into consideration the distribution of data nodes, streaming capabilities, aggregation and queryability options and how we can integrate the different data processing software, like Spark, that can benefit from subtle but substantial model changes. A clear example is when embedding or referencing documents and their implications on high speed processing. Over the course of this talk we will detail the benefits of a good document model for the operational workload. As well as what type of transformations we should incorporate in our document model to adjust for the high speed processing capabilities of Spark. We will look into the different options that we have to connect these two different systems, how to model according to different workloads, what kind of operators we need to be aware of for top performance and what kind of design and architectures we should put in place to make sure that all of these systems work well together. Over the course of the talk we will showcase different libraries that enable the integration between spark and MongoDB, such as MongoDB Hadoop Connector, Stratio Connector and MongoDB Spark Native Connector. By the end of the talk I expect the attendees to have an understanding of: How they connect their MongoDB clusters with Spark Which use cases show a net benefit for connecting these two systems What kind of architecture design should be considered for making the most of Spark + MongoDB How documents can be modeled for better performance and operational process, while processing these data sets stored in MongoDB. The talk is suitable for: Developers that want to understand how to leverage Spark Architects that want to integrate their existing MongoDB cluster and have real time high speed processing needs Data scientists that know about Spark, are playing with Spark and want to integrate with MongoDB for their persistency layer

Ams adapters

Bruno Alló Bacarini

AMS adapters in Rails 5 are important for building a wonderful RESTful API because they provide hypermedia controls and links in the API response. The JSON API adapter in particular generates responses that follow the JSON API specification by including links, relationships, pagination metadata, and embedded resources. Adapters allow Rails to render different representation formats like JSON API, customize the API structure, and improve the developer experience of the API through conventions like hypermedia controls and links. However, there is still work to be done on adapters, like improving deserialization, documentation, and better supporting JSON API conventions fully.

OData: Universal Data Solvent or Clunky Enterprise Goo? (GlueCon 2015)

Pat Patterson

Why would anyone but the most pedestrian enterprise developer be interested in a data access protocol originally designed by Microsoft, implemented in XML and handed to OASIS for standardization? The Open Data Protocol, or OData for short, has evolved into a clean, RESTful interface for CRUD operations against data services. Alongside the usual enterprise suspects such as Microsoft, Salesforce and IBM, OData has been adopted by government and non-profit agencies to open up their data and make it accessible to the public. For developers wanting to consume data, or create their own OData services, there's no shortage of open source options, from Apache Olingo in Java to node-odata and ODataCpp. Whether you're accessing customer orders in SAP or the Whitehouse visitor book, you're going to need some OData smarts.

JSON-LD Update

Gregg Kellogg

1) JSON-LD has seen widespread adoption with over 2 million HTML pages including it and it being a required format for Linked Data platforms. 2) A primary goal of JSON-LD was to allow JSON developers to use it similarly to JSON while also providing mechanisms to reshape JSON documents into a deterministic structure for processing. 3) JSON-LD 1.1 includes additional features like using objects to index into collections, scoped contexts, and framing capabilities.

Solutions for bi-directional integration between Oracle RDBMS & Apache Kafka

Guido Schmutz

Apache Kafka is a popular distributed streaming data platform. A Kafka cluster stores streams of records (messages) in categories called topics. It is the architectural backbone for integrating streaming data with a Data Lake, Microservices and Stream Processing. Data sources flowing into Kafka are often native data streams such as social media streams, telemetry data, financial transactions and many others. But these data stream only contain part of the information. A lot of data necessary in stream processing is stored in traditional systems backed by relational databases. To implement new and modern, real-time solutions, an up-to-date view of that information is needed. So how do we make sure that information can flow between the RDBMS and Kafka, so that changes are available in Kafka as soon as possible in near-real-time? This session will present different approaches for integrating relational databases with Kafka, such as Kafka Connect, Oracle GoldenGate and bridging Kafka with Oracle Advanced Queuing (AQ).

Aligning Web Services with the Semantic Web to Create a Global Read-Write Gra...

Markus Lanthaler

Presentation of the paper "Aligning Web Services with the Semantic Web to Create a Global Read-Write Graph of Data" gave at the 9th IEEE European Conference on Web Services (ECOWS 2011) in Lugano, Switzerland. Despite significant research and development efforts, the vision of the Semantic Web yielding to a Web of Data has not yet become reality. Even though initiatives such as Linking Open Data gained traction recently, the Web of Data is still clearly outpaced by the growth of the traditional, document-based Web. Instead of releasing data in the form of RDF, many publishers choose to publish their data in the form of Web services. The reasons for this are manifold. Given that RESTful Web services closely resemble the document-based Web, they are not only perceived as less complex and disruptive, but also provide read-write interfaces to the underlying data. In contrast, the current Semantic Web is essentially read-only which clearly inhibits net-working effects and engagement of the crowd. On the other hand, the prevalent use of proprietary schemas to represent the data published by Web services inhibits generic browsers or crawlers to access and understand this data; the consequence are islands of data instead of a global graph of data forming the envisioned Semantic Web. We thus propose a novel approach to integrate Web services into the Web of Data by introducing an algorithm to translate SPARQL queries to HTTP requests. The aim is to create a global read-write graph of data and to standardize the mashup development process. We try to keep the approach as familiar and simple as possible to lower the entry barrier and foster the adoption of our approach. Thus, we based our proposal on SEREDASj, a semantic description language for RESTful data services, for making proprietary JSON service schemas accessible.

A Semantic Description Language for RESTful Data Services to Combat Semaphobia

Markus Lanthaler

The document proposes a semantic description language (SEREDASj) to provide machine-readable descriptions of RESTful web services. It aims to address the lack of standards for describing REST APIs and help combat "semaphobia", the fear of semantics. The language builds on previous work but is tailored specifically for REST by focusing on simplicity and supporting many use cases including discovery and composition of RESTful services.

What Not to Document and Why_ (North Bay Python 2024)

Margaret Fero

We’re hopefully all on board with writing documentation for our projects. However, especially with the rise of supply-chain attacks, there are some aspects of our projects that we really shouldn’t document, and should instead remediate as vulnerabilities. If we do document these aspects of a project, it may help someone compromise the project itself or our users. In this talk, you will learn why some aspects of documentation may help attackers more than users, how to recognize those aspects in your own projects, and what to do when you encounter such an issue. These are slides as presented at North Bay Python 2024, with one minor modification to add the URL of a tweet screenshotted in the presentation.

Coordinate Systems in FME 101 - Webinar Slides

Safe Software

If you’ve ever had to analyze a map or GPS data, chances are you’ve encountered and even worked with coordinate systems. As historical data continually updates through GPS, understanding coordinate systems is increasingly crucial. However, not everyone knows why they exist or how to effectively use them for data-driven insights. During this webinar, you’ll learn exactly what coordinate systems are and how you can use FME to maintain and transform your data’s coordinate systems in an easy-to-digest way, accurately representing the geographical space that it exists within. During this webinar, you will have the chance to: - Enhance Your Understanding: Gain a clear overview of what coordinate systems are and their value - Learn Practical Applications: Why we need datams and projections, plus units between coordinate systems - Maximize with FME: Understand how FME handles coordinate systems, including a brief summary of the 3 main reprojectors - Custom Coordinate Systems: Learn how to work with FME and coordinate systems beyond what is natively supported - Look Ahead: Gain insights into where FME is headed with coordinate systems in the future Don’t miss the opportunity to improve the value you receive from your coordinate system data, ultimately allowing you to streamline your data analysis and maximize your time. See you there!
