Abstract
Post implementation, HUBzero(TM) has been well accepted as a knowledge management and collaboration platform for the reliability engineering (RE) division of a large consumer goods company. RE tools such as Failure Mode Effects & Criticality Analysis (FMECA), Reliability Growth Curves, and Shakedown Testing are being used in the organization in form of spreadsheets. Automated workflows have been developed to collect and publish good quality RE analyses on HUBzero for benchmarking and reuse. The WEB2.0 features of HUBzero such as tags, ratings and reviews help the users to browse efficiently through the various RE tool analyses on HUBzero. In this paper, we will discuss our new approach for intelligently assigning keywords to each of the reliability tool spreadsheets in an automated manner. We are using the principles of text mining for keyword extraction, customized for RE tools which contain data structured in a unique manner. These keywords will be used as hierarchical tags, ranked in order of relevance with the particular RE spreadsheet. These tags will not only provide users a good idea about the content of the file, but also will enhance the browsing to related content.

1. Introduction
In an ongoing project with the reliability engineering division of a large consumer products company, HUBzero (also referred sometimes as HUB in the paper) has been successfully implemented as a knowledge base of different reliability tools being used in the company such as FMECA, Reliability Growth Analysis and Shakedown Testing. The FMECA tool analyzes failures of a system by identifying and classifying the failure modes and the causes and effects of each potential failure mode on system service and subsequently defining appropriate detection procedures and corrective actions. The Reliability Growth Analysis tool uses Logistics model to determine various developmental data such as time-to-failure, discrete (success/failure) and reliability values at different times or stages. The Shakedown Testing tool is used for recording the results of equipment tests made during installation work. These RE tools are used within the organization in form of Microsoft Excel files with a set of predefined columns where engineers have to fill their analysis depending on the tool being used.
