Smarter Together - Bringing Relational Algebra, Powered by Apache Calcite, in...Julian Hyde
What if Looker saw the queries you just executed and could predict your next query? Could it make those queries faster, by smarter caching, or aggregate navigation? Could it read your past SQL queries and help you write your LookML model? Those are some of the reasons to add relational algebra into Looker’s query engine, and why Looker hired Julian Hyde, author of Apache Calcite, to lead the effort. In this talk about the internals of Looker’s query engine, Julian Hyde will describe how the engine works, how Looker queries are described in Calcite’s relational algebra, and some features that it makes possible.
A talk by Julian Hyde at JOIN 2019 in San Francisco.
Complex hierarchical relationships between entities can only be mapped with difficulty in a relational database and demanding queries are usually quite slow.
Graph databases are optimized for exactly these kinds of relationships and can provide high-performance results even with huge amounts of data. Moreover, not only the entities that are stored in the database, have attributes, but also their relationships. Queries can look at entities as well as their relationships.
Get to know the basics of graph databases, using Neo4j as an example, and see how it is used C# projects.
Neo4j is a powerful and expressive tool for storing, querying and manipulating data. However modeling data as graphs is quite different from modeling data under a relational database. In this talk, Michael Hunger will cover modeling business domains using graphs and show how they can be persisted and queried in Neo4j. We'll contrast this approach with the relational model, and discuss the impact on complexity, flexibility and performance.
Graph databases are a type of NoSQL database that use a graph data model and can be used in a variety of natural language processing techniques.
During this webinar, William Lyon (Developer Relations Enginner, Neo4j) provided an overview of graph databases, followed by a survey of the role for graph databases in natural language processing tasks, including modeling text as a graph, mining word associations from a text corpus using a graph data model, and, mining opinions from a corpus of product reviews. He concluded with a demonstration of how graphs can enable content recommendation based on keyword extraction.

Improving Search in Workday Products using Natural Language ProcessingDataWorks Summit
Workday is a leading provider of cloud-based enterprise software products such as Human Capital Management, Talent, Finance, Student, Planning etc. These products produce a wealth of natural language data. However, this data is unstructured and denormalized. Retrieving relevant information from such data is a challenging task. Using simple index-based search methods can only take us so far. The Data Science team at Workday is determined to apply Machine Learning and AI to make search better across Workday’s products.
In this session, we present to you, how we use word embeddings to normalize the data and add structure to it. We will also talk about using word representations to make search intelligent. The specific use cases we will discuss are adding synonyms detection and entity-recommendation.
In this talk, we will focus on the word-embeddings techniques explored, metrics used to evaluate Natural Language Processing Models, tools built, and future work as a part of improving search.

There’s been a lot of recent work on representing words as vectors with neural networks. These representations referred to as “neural embeddings” or “word embeddings”.
This presentation was provided by Kyle Lo of The Allen Institute for AI (AI2) during the NISO hot topic event "Preprints." The virtual conference was held on April 21, 2021.
The trend nowadays is to represent the relationships between entities in a graph structure. Neo4j is a NOSQL graph database, which allows for fast and effective queries on connected data. Implementation of own algorithms is possible, which can improve the functionality of built in API. We make use of the graph database to model and recommend movies and other media content.
One of the biggest challenges in the data age is overcoming the problematic belief that data has all the answers. The truth is – data is a resource, not a solution. In order to extract valuable and actionable insights, it is necessary to ask and re-ask certain questions. This talk is about figuring out what these questions are and exposes some of the limitations of common, and seemingly intuitive, approaches to data problems. As an alternative, I introduce the concept of using human-centered design principles and an iterative process to approach what you do with Big (and small) Data. As exemplars, I will walk-through a quick informal example and a real Datascope client project to highlight the flexibility and speed of these techniques.
The Reason Behind Semantic SEO: Why does Google Avoid the Word PageRank?Koray Tugberk GUBUR
This article delves into the concepts of Semantic SEO, Topical Authority, and PageRank, exploring their relationships and how they benefit both website owners and search engines. By leveraging Natural Language Processing (NLP) techniques, Semantic SEO improves search engine comprehension of content and enhances user experience, ultimately leading to better search results.
In the ever-evolving world of Search Engine Optimization (SEO), understanding the intricate connections between Semantic SEO, Topical Authority, and PageRank is crucial for webmasters, content creators, and marketers. These concepts play a vital role in enhancing the visibility and relevance of websites in search results.
Semantic SEO: Going Beyond Keywords
Semantic SEO involves optimizing content by focusing on the meaning and context of words, phrases, and sentences rather than merely targeting specific keywords. This is achieved through NLP techniques such as topic modeling, sentiment analysis, and entity recognition, which allow search engines to comprehend the true essence of content.
Topical Authority: Establishing Expertise and Trustworthiness
Topical Authority refers to the perceived expertise of a website or content creator in a specific subject area. By producing high-quality, relevant, and in-depth content, websites can establish themselves as authorities, earning the trust of both users and search engines. This translates into higher search rankings and increased visibility.
PageRank: Measuring the Importance of Webpages
PageRank is an algorithm used by Google to determine the significance of a webpage by analyzing the quality and quantity of its inbound links. A higher PageRank implies that a website is more authoritative and valuable, thus warranting a better position in search results.
The Interrelation of Semantic SEO, Topical Authority, and PageRank
Semantic SEO, Topical Authority, and PageRank are interconnected concepts that work in tandem to improve a website's search performance. By focusing on Semantic SEO, content creators can enhance their Topical Authority and establish a solid online presence. This, in turn, can lead to higher PageRank and improved search visibility.
The Benefits of Semantic SEO for Search Engines
Semantic SEO not only benefits website owners but also search engines by reducing the cost of understanding documents. With the help of NLP techniques, search engines can efficiently analyze and comprehend content, making it easier to identify and index relevant webpages. This ultimately leads to more accurate search results and a better user experience.
In conclusion, embracing Semantic SEO, Topical Authority, and PageRank is essential for achieving higher search rankings and increased online visibility. By leveraging NLP techniques, Semantic SEO offers a more sophisticated and efficient approach to understanding and optimizing content, ultimately benefiting both website owners and search engines.

How Graph Algorithms Answer your Business Questions in Banking and BeyondNeo4j
Graph algorithms are powerful tools, and there’s a lot of excitement about their applications for data science. It can sometimes be difficult, however - especially for those of us who aren’t data scientists - to know how they might be applied to a particular data set or a specific business problem. There are graph algorithms for centrality and importance measurement, community detection, similarity comparison, pathfinding, and link prediction. Which ones should you use on your data, and which ones might be most useful in answering your business questions?
In this presentation, we’ll look at a few examples of Neo4j graph algorithms, and see how they can be applied to data and business problems from the banking industry. We’ll discuss what kinds of data are appropriate for different types of algorithms, show how to model and structure data to work with graph algorithms, and run through some real-world scenarios demonstrating the use of graph algorithms on a sample banking data set.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
