Technologies such as Hadoop have addressed the "Volume" problem of Big Data, and technologies such as Spark have recently addressed the "Velocity" problem – but the "Variety" problem is largely unaddressed – there is a lot of manual "data wrangling" to mange data models.
These manual processes do not scale well. Not only is the variety of data increasing, also the rate of change in the data definitions is increasing. We can’t keep up. NoSQL data repositories can handle storage, but we need effective models of the data to fully utilize it.
This talk will present tools and a methodology to manage Big Data Models in a rapidly changing world. This talk covers:
Creating Semantic Metadata Models of Big Data Resources
Graphical UI Tools for Big Data Models
Tools to synchronize Big Data Models and Application Code
Using NoSQL Databases, such as Amazon DynamoDB, with Big Data Models
Using Big Data Models with Hadoop, Storm, Spark, Giraph, and Inference
Using Big Data Models with Machine Learning to generate Predictive Models
Developer Collaborative/Coordination processes using Big Data Models and Git
Managing change – Big Data Models with rapidly changing Data Resources
A Survey on Approaches for Frequent Item Set Mining on Apache HadoopIJTET Journal
Abstract— In data mining, association rule mining is one of the major techniques for discovering meaningful patterns from large collection of data. Discovering frequent item sets play an important role in mining association rules, sequence rules, web log mining and many other interesting patterns surrounded by complex data. Frequent Item set Mining is one of the classical data mining tribulations in most of the data mining applications. Apache Hadoop is a major innovation in the IT market place last decade. From modest beginnings Apache Hadoop has become a world-wide adoption in data centers. It brings parallel processing in hands of average programmer. This paper presents a literature analysis on different techniques for mining frequent item sets and frequent item sets on Hadoop.

Palestra sobre Big data: Descoberta de conhecimento em ambientes de big data e computação na nuvem apresentada por Nelson Favilla durante o Rio Info 2014
Big Data raises challenges about how to process such vast pool of raw data and how to aggregate value to our lives. For addressing these demands an ecosystem of tools named Hadoop was conceived.
this is a presentation on hadoop basics. Hadoop is an Apache open source framework written in java that allows distributed processing of large datasets across clusters of computers using simple programming models.
Solr is a great tool to have in the data scientist toolbox. In this talk, I walk through several demos of using Solr to data science activities as well as explore various use cases for Solr and data science
In just a few short years, search has quickly evolved from being a small text box in the nether regions of a website to being front and center in our lives. Increasingly, however, search engine technology is also being used for practical, real time recommendations, events processing, complex spatial functionality and time series analysis capable of not only matching user's queries in text, but also driving real time decision making and analytics. In fact, open source Apache Lucene/Solr can do all of this and more by taking advantage of new data structures and algorithms that complement more traditional IR approaches. In this demo-driven talk, Lucene committer Grant Ingersoll will take a look at some of the new and exciting ways users are leveraging Lucene/Solr and related technology to drive deeper insight into information needs that go beyond keywords in a text box.
A 1 hour intro to search, Apache Lucene and Solr, and LucidWorks Search. Contains a quick start with LucidWorks Search and a demo using financial data (See Github prj: http://bit.ly/lws-financial) as well as some basic vocab and search explanations
http://sigir2013.ie/industry_track.html#GrantIngersoll
Abstract: Apache Lucene and Solr are the most widely deployed search technology on the planet, powering sites like Twitter, Wikipedia, Zappos and countless applications across a large array of domains. They are also free, open source, extensible and extremely scalable. Lucene and Solr also contain a large number of features for solving common information retrieval problems ranging from pluggable posting list compression and scoring algorithms to faceting and spell checking. Increasingly, Lucene and Solr also are being (ab)used to power applications going way beyond the search box. In this talk, we'll explore the features and capabilities of Lucene and Solr 4.x, as well as look at how to (ab)use your search engine technology for fun and profit.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

The key trends across hardware, cloud and open-source; exploring how these areas are likely to mature and develop over the short and long-term, and then considering how organisations can position themselves to adapt and thrive.
"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
