IBM Watson Analytics preps the data so you don't have to

17/09/2014 by


With the newest commercial service to spring from its highly publicized Watson cognitive computing initiative, IBM is attempting to streamline the process of analyzing data so business managers can pull insights from data sets without the help of IT experts.

"Often what business users do is rely on a data scientist or business analysts to help them, which can be too slow, or those people may not be available. So they make a decision without any analysis," said Eric Sall, IBM vice president of marketing for business analytics.

The new service, IBM Watson Analytics, launched as an invitational beta trial on Tuesday, can walk the user through data analysis by way of a series of interactive steps. In an event in New York Tuesday, the company demonstrated how the service would work.

The service can upload data, cleanse it, understand the user's requirements through an interactive natural language query session and then produce a range of analysis and accompanying visualizations that may be of interest.

"It's the full range of analytical capabilities integrated together in one user experience," Sall said in an interview before the launch event.

The service is powered by a set of different IBM analysis technologies, such as Cognos and SPSS, and adds some machine learning capabilities from the Watson project.

In a series of presentations, IBM showed how Watson Analytics could be used. None of the demonstrations were live; the audience was shown screen shots taken before the presentation. But they offered a glimpse of how the technology, which IBM is still refining, would work.

As a first step, the user uploads a CSV (Comma Separated Values) or XLS (Excel Binary File Format) flat file to the service. A CSV file can easily be extracted from a spreadsheet or a database table. The data values are separated by commas and each column of data has a name, usually given to it by the administrator who created the table or spreadsheet.

Watson first analyzes the file to estimate the quality of the data. A data set may have missing values, or be too small to draw meaningful conclusions from. Certain columns may not have any statistical interest -- they all may have the same value for instance. Watson offers an overall score of the cleanliness of the data, as well as how much potentially interesting analysis could be derived from the set.

The service will then examine the data set for any interesting correlations that may be occurring, and look for more obscure second-order effects that someone looking at a spreadsheet may miss. In effect, Watson Analytics runs through the data and prepares visualizations for all the possible relations among the data elements, emphasizing those that might be of most interest to the user. The user can then click on the charts of interest, and Watson makes notes of what its users are looking for.

It offers both basic analysis and predictive analysis, where it can make guesses at future behavior based on metrics of past behavior.

This is not to say the Watson does all the work of analyzing the data. Helping Watson understand the data requires that all the column rows be descriptively named. The set-up process also requires domain experts to identify those columns that they are most interested in learning more about, to prevent Watson from endlessly churning up relations of little interest.

During a customer panel at the event, a number of data scientists and business intelligence system managers expressed optimism for the new offering.

Justin Croft, manager for brand platforms and analytics for U.S. wireless communication provider C Spire, noted that this service could be immediately useful to the company's sales and marketing staff, who could use it to ferret out reasons why there may be a spike or dip in sales volumes. Typically, the staff may have "far more questions than there is time to track down the answers," he said.

Though IBM is marketing the service directly to end users, it can also be embedded in other enterprise software. SugarCRM, electronics distributor AVNET, and Truven Health Care analytics have all shown an interested in folding Watson capabilities into their own offerings

IBM itself is folding Watson Analytics into another, as-of-yet unnamed cloud service for its Smarter Workforce portfolio that it plans to launch later this month for human resource (HR) departments. Among the features offered by this service is a Watson Analytics powered service allowing HR professionals to ask questions about information typically captured by HR offices.
