  • Text Mining Tools
    Chapter 21 Text mining tools A. Zanasi TEMIS SA, France. Modena & Reggio Emilia University, Italy. Introduction Several tools are already available in the text mining (or more generally un- structured data) quickly growing market. We recognize the text mining market as composed by pure players (companies which develop text mining software, e.g. Clearforest, Inxight, Temis), indirect players (which integrate text mining into their offering, e.g. IBM, SAS, SPSS), partial players (companies which use text mining to improve their core business, e.g. Fast, Verity). A section is dedicated to each player which provided us with their company description, and a cumulative section listing the most known players in the text mining arena. Hundreds of other companies are already working successfully in the worldwide market. For a list of them, go to www.kdnuggets.com. 1 Megaputer intelligence 1.2 Company description Megaputer Intelligence (www.megaputer.com) was founded in 1993. The company provides a family of tools for the analysis of structured data and text. 1.3 Products Megaputer Intelligence offers two products: PolyAnalyst for Text™, aimed pri- marily at the analysis of incident reports, survey responses and customer comm- unications data and TextAnalyst™ . PolyAnalyst for Text™ performs semantic text analysis, record coding, identi- fication and visualization of patterns and clusters of information, automated or manual taxonomy creation and editing, taxonomy-based forced or self-learning WIT Transactions on State of the Art in Science and Eng ineering, Vol 17, © 2005 WIT Press www.witpress.com, ISSN 1755-8336 (on-line) doi:10.2495/978-1-85312-995-7/21 316 Text Mining and its Applications to Intelligence, CRM and Knowledge Management categorization of documents, text OLAP, link analysis, and interactive visual processing of various combinations of structured and unstructured data.

  • Polyanalyst Technical Capabilities and System Requirements
    PolyAnalyst 6 Technical capabilities and system requirements © 2007 Megaputer Intelligence Inc. All rights reserved. PolyAnalyst Features Client/Server architecture Server architecture enables the implementation of PolyAnalyst 6 as an enterprise level analytical system. It facilitates the collaboration between data analysts working on the same projects and sharing various related resources such as analysis scenarios, dictionaries, taxonomies, and multi-dimensional matrices. Server architecture helps enhance the performance of the system by performing calculations on the most powerful machines, reducing data transfer over the network, scheduling execution of tasks at a given time, and generating custom reports and condition based alerts for different groups of business users. It provides the centralized management and audit of the list of system users and their actions. Security Recognizing that data is one of the most valuable and sensitive assets of a modern organization, PolyAnalyst provides solid mechanisms to ensure data security. Communications between client and server are performed in a fully encrypted manner with a new encryption key generated by the server for every communication session. PolyAnalyst supports secure user login based on user rights and passwords and keeps track of individual and group rights and sequences of actions carried out by the users. In addition, full compliance with the requirements of the HIPAA legislation facilitates PolyAnalyst implementations at healthcare and insurance organizations. Scalability and Performance PolyAnalyst provides industrial level scalability: it can handle huge amounts of data within reasonable time intervals. This scalability is ensured through a combination of several factors. PolyAnalyst utilizes hard disk instead or RAM for holding all data and supporting meta-information.
