EconometricsEconometrics - Statistical software that is specialised for econometric analysis. Econometrics is the application of statistical or quantitative methods to understand economic issues and test theories, and models. It is the study of economic models, mathematical statistics, and economic data.
EDAElectronic Design Automation - Design electronic systems such as printed circuit boards and integrated circuits
GenomeGenome Browsers (Desktop) - Visualize and browse entire genomes with annotated data with these standalone desktop genome browsers
Genome Browsers - Web BasedGenome Browsers (Web Based) - Visualize and browse entire genomes with annotated data with these web based genome browsers

Natural Language ProcessingNatural Language Processing - Field of computer science, artificial intelligence, and computational linguistics concerned with the interactions between computers and human (natural) languages
Natural Language ProcessingPython Natural Language Processing - Python and R stand toe-to-toe in data science. But in the field of NLP, Python stands very tall
Natural Language Processing
R Natural Language Processing - R offers competent libraries for NLP. Many of the techniques such as word and sentence tokenization, n-gram creation, and named entity recognition are easily performed in R
Natural Language ProcessingJava Natural Language Processing - Java runs Python and R close when it comes to NLP. Java is one of the most widely used programming languages owing part of its popularity to its extensive ecosystem
Natural Language ProcessingC++ Natural Language Processing - C++ based NLP tools. Many challenges in NLP involve natural language understanding

Get Started with Data Science with two tutorials to explore data science using Python or R. Both tutorials tackle the same basic data science task: manipulate and then visualise a data set.

Big Data
Big Data is an all-inclusive term that refers to data sets so large and complex that they need to be processed by specially designed hardware and software tools.
Big Data - Data AnalysisData Analysis Tools - Examine huge quantities of unstructured data to find patterns, correlations, and more with these distributed systems.
Big Data - File SystemsFile Systems - We examine storage solutions which are designed to scale out on multiple servers. They support high performance data and offer consistent access to a common set of data from multiple servers.
Big Data - Key Value StoresKey Value Stores - Key value stores refers to a general concept of database where entities (values) are indexed using a unique key. They allow the application to store its data in a schema-less way. Data can be stored in a datatype of a programming language or an object.
Big Data - Native XML DatabasesNative XML Databases - Store data and documents without requiring a database schema. An XML database allows data to be stored in the Extensible Markup Language (XML) format.
Big Data - Search EnginesSearch Engines - Full-featured search engines through an application programming interface which are designed for performing information retrieval functions on Big Data.
Electronic Medical RecordsElectronic Medical Records - This type of software is used in a hospital and doctor’s surgery to capture medical information, reducing the amount of physical records, and the costs associated in storing them
Eye CareEye Care - There are lots of simple steps you can take to reduce eye strain and fatigue. But there's also software to help
Food and DrinkFood and Drink - Nutrition, diet and BEER! Cook delicious food, adopt a healthy diet, and use software to help you brew ale, lager, and stout
