How are text mining tools used in SAS?

It discovers unseen patterns of words in data or known words or textual patterns in undetected records in data bases. SAS has its own dedicated text mining tools such as SAS® Contextual Analysis, SAS® Text Minor. However, their use by general users is precluded by affordability and availability.

How are string functions used in text mining?

We developed a simple but robust approach for text mining using a combination of three simple SAS string functions, namely Index, IndexW and SoundeX in the SAS® macro environment. Our application generates Bag of Words (BoW), Term Document Matrix (TDM), Term frequencies and other standard outcomes needed to proceed to advance text analysis.

What is the term document matrix in SAS?

Term Document Matrix (TDM):a two dimensional array with rows representing the documents, columns representing the terms (represented by variable names assigned in ITM) and cells representing the frequencies of successful matches of objective terms in the document. Key SAS string functions used in this text mining application

Are there any simple string functions in SAS?

However, their usage by general Base SAS users is precluded by affordability, availability and flexibility. We developed a simple but robust approach for text mining using a combination of three simple SAS string functions, namely Index, IndexW and SoundeX in the SAS® macro environment.

Which is a component of SAS Enterprise Miner?

SAS Text Miner is a component of SAS® Enterprise Miner. SAS Enterprise Miner must be installed on the same machine. SAS High-Performance Text Mining runs on a computer grid or a single computer system with multiple CPUs. Text algorithms are multi-threaded and process in-memory, which increases responsiveness and concurrency, reducing I/O burden.

How is SAS used to analyze text data?

Text analytics are based on statistical, linguistic and machine learning rules, and turn unstructured data into actionable insights. SAS offers many different solutions to analyze text. The papers included in this special collection demonstrate the wide-ranging capabilities and applications of text analytics across several industries.

Is there a post installation document for SAS Text Miner 4.2?

The post-installation document that was available with SAS Text Miner 3.2 is no longer necessary for SAS Text Miner 4.1 because SAS 9.2 uses the SAS Deployment Wizard for installation and configuration of SAS products, as described in the first guide below.
