Hadoop involvement in Anti-Spam for e-mail

Spam e-mail is one of the biggest malaise of an interconnected world. There have been numerous solutions and counter proposals; millions of $ have went in preventing and blocking spam. Let us understand how MapReduce and Hadoop can step in anti-spam fight. 

First, lets look at a MapReduce approach involving Naive Bayesian classifier

A deeper look into Hadoop involvement in anti-spam initiative at Yahoo - look at slide 32 for possible algorithmic approach alternates.

Finally, a commercial offering by Proof Point - look slide 27 onward for architectural details.

Data deduplication tactics with HDFS and MapReduce

As the amount of data continues to grow exponentially, there has been increased focus on stored data reduction methods. Data compression, single instance store and data deduplication are among the common techniques employed for stored data reduction.
Deduplication often refers to elimination of redundant subfiles (also known as chunks, blocks, or extents). Unlike compression, data is not changed and eliminates storage capacity for identical data. Data deduplication offers significant advantage in terms of reduction in storage, network bandwidth and promises increased scalability.
From a simplistic use case perspective, we can see application in removing duplicates in Call Detail Record (CDR) for a Telecom carrier. Similarly, we may apply the technique to optimize on network traffic carrying the same data packets.
Some of the common methods for data deduplication in storage architecture include hashing, binary comparison and delta differencing. In this post, we focus on how MapReduce and…

5 online tools in data visualization playground

While building up an analytics dashboard, one of the major decision points is regarding the type of charts and graphs that would provide better insight into the data. To avoid a lot of re-work later, it makes sense to try the various chart options during the requirement and design phase. It is probably a well known myth that existing tool options in any product can serve all the user requirements with just minor configuration changes. We all know and realize that code needs to be written to serve each customer’s individual needs.
To that effect, here are 5 tools that could empower your technical and business teams to decide on visualization options during the requirement phase. Listed below are online tools for you to add data and use as playground.
1)      Many Eyes: Many Eyes is a data visualization experiment by IBM Researchandthe IBM Cognos software group. This tool provides option to upload data sets and create visualizations including Scatter Plot, Tree Map, Tag/Word cloud and ge…

Hadoop use cases in the Bitcoin economy

Bitcoin as a decentralized P2P virtual currency has become a hot topic of discussion and analysis in the last few months. Due to its unregulated nature and possibility to exchange it for real life goods, services or real currency, the currency is being used for both legit and illegal trades. Further, the transaction data is publicly available online albeit with anonymous ids. In this post, lets explore the possible Bitcoin economy use cases for Hadoop ecosystem products.
Bitcoins were first suggested in 2008 by Satoshi Nakamoto. Participants of this economy acquire a Bitcoin wallet and Bitcoin addresses. The Bitcoin address send and receive Bitcoins (BTC) in a manner analogous to sending and receiving e-mails from e-mail address. The network relies on a shared transaction log called block chain where all confirmed transactions are included without any exception. The system uses a distributed consensus system called Mining that is used to confirm waiting transactions by including them i…
