Context Matters When Text Mining

Context Matters When Text Mining

Many times the most followed approach can result in failure.  The reason has more to do with thinking that one approach works in all cases.  This is specially true in text mining.  For instance, a common approach in clustering documents is to create tf-idf matrix for all documents, use SVD or other dimension reduction algorithm and then use a clustering.  In most cases, this will work; However, as I will present here,  there are instances…

Guide To Budget Friendly Data Mining

Unlike traditional application programming, where API functions are changing every day, database programming basically remains the same. The first version of Microsoft Visual Studio .NET was released in February 2002, with a new version released about every two years, not including Service Pack releases. This rapid pace of change forces IT personnel to evaluate their corporation’s applications every couple years, leaving the functionality of their application intact but with a completely…

Embodiment from Codified Narrative

For a number of months, I have been generating codified narrative from films, fairytales, paintings, court cases, and news events. Codified narrative might be described as a tokenized rendition of the underlying content. There are many ways to do a rendering. Imagine asking 100,000 people to write a story based on the same general details such as scenery, major events, and specific outcomes. To the extent there are commonalities in the resulting storylines, I would say that "social…

How Big Data Can Predict Football’s Rising Stars (VIDEO)

Did you know that Big Data can help us predict who the future football stars will be? This is precisely what happened in Riyad Mahrez’s case, PFA Player of the Year, who has conquered the English Premier League with Leicester City.

Free data mining programs for everyday use

If you want quickly to get started with data analysis, here is my advise on free software programs that I use every day for data analysis, statistics and data mining.

R-package - a software for statistical computing written in C. Script oriented.

  • Pros: widely used, simple, extensive documentation.
  • Cons: less options for graphics compared to competitors, no…

Inferential Modeling and Application of Analogs

When discussing the use of algorithms, the issue of durability or portability has to be considered. For example, a stock trading algorithm might be used in a missile guidance system. The algorithm would have to operate on an abstract kinetic level rather than for a specific application. I have written in the past about using the same algorithm to study stocks, earthquakes, hurricanes, electro-cardiograms, and attempts at evasion - using my mouse in a game environment. Wouldn't an abstraction…

How to Cross Link Data and Why You Should Do So

The 3Vs model is the foundation of big data - Volume, Velocity, and Variety. It is used to express the key features of big data problems - for me, this is about to change. Big Data is not just about size, speed, or formats, the contextual enrichment is the most critical factor of how we unmask the best value out of data. How well you bring seemingly unrelated data together and identify the valuable connections determines how much power you unleash from your…

Sensitivity Mapping of Document Databases

I rarely get to use a walkie-talkie during a course in school. As the snapshot of my desktop shows on the image below, I had both a multi-line telephone and portable radio. Just before the exam, I participated in a simulation. Our tabletop exercise contained an emergency scenario: a train derailment involving the evacuation of residents. I served as the Social Services Director. Although I didn't choose this role for myself, I thought it made sense given my graduate degree in the area of…

Big Data, Meet Dynamic Semantic Publishing: Altering the Media & Publishing Landscape

How many times a day do we ourselves, or hear someone else, utter the phrase “Google it”? It’s hard to imagine that a phrase so ubiquitous and universally understood has been around for less than two decades. The word “Google” has become synonymous with online search, and when we think about why this, it’s because Google yields the most relevant, comprehensive results, quickly. Essentially, it has changed the way we find and interact with content and information.

We’ve seen the…

The Hype Around Graph Databases And Why It Matters

Organizations are struggling with a fundamental challenge – there’s far more data than they can handle.  Sure, there’s a shared vision to analyze structured and unstructured data in support of better decision making but is this a reality for most companies?  The big data tidal wave is transforming the database management industry, employee skill sets, and business strategy as organizations race to unlock meaningful connections between disparate sources of…

Discovering the relationship of the G20 members using Data Mining

It takes just a little talk with me to know that I'm a fan of the financial market and many subjects related to economics. Today I want to show an application involving news on the web, Python, MongoDB and the Gephi, a software for visualization and manipulation of social networks.

Our goal is to verify that the amount of joint occurrences of G20 countries (specifically Brazil) published in the news related to the financial market…

Bring Data Science to Everyday Life

Data science might be one of the hottest buzzwords in 2013. But is it only a marketing gimmick? I don’t think so. In my opinion, data science can be the best protocol that reveals what’s happening every day in the real world.

The data science incorporates mathematics, statistics, computer science and…

Your custom MDM solution: Don’t make these mistakes (Part 1)

Your custom MDM solution: Don’t make these mistakes (Part 1)

Most MDM implementations will be based on a commercial software product.  By relying on a packaged solution, the architectural considerations have been addressed by the software vendor, allowing the project team to focus on the data management considerations.  However, there are cases when a custom MDM solution may be needed.  When proceeding down the path of custom development for MDM, we have some advice for you:…

Not just analyze the log, mine it.

Much more devices held, much more messages sent, much more data up in the air.

Upon the arrival of IOT (Internet of Things) era, number of connected devices grows rapidly, the signals of which stack up mines containing valuable, hidden insights.

We used to analyze log files for risk management, spotting the anomalies and exceptions based on outlined records. Via the ever-richer meta data and context, we are entitled to weave more story from the strings now. By union or…

Java Coding Samples for Online Data-mining

In this post, I discuss the basic characteristics of code that I have personally used to extract online data - in a process these days often called data-mining.  I intend to cover some general features.  Those that wish to do so can also compile the coding samples.

Over the years, I have programmed in a number of computer programming languages including Visual Basic, Perl, Python, and LISP (AutoLISP).  The coding samples on this blog are written in Java, my language of…
