Integrated into Microsoft Internet Explorer® for Windows®, netXtract delivers a breakthrough approach to document navigation and relevance determination. netXtract automatically indexes each document displayed by IE, extracts all contexts for any key term you choose and allows you to “jump” directly to the context you find most interesting. netXtract also allows you to define custom filters, or “dictionaries” of related terms by area of study, interest or business focus (e.g. medical, legal, financial, business intelligence, etc.). Build your own personal knowledge base Once you’ve found relevant information, you decide exactly what to save for future reference. netXtract allows you to build a local personal Knowledge Base of any text you select from documents displayed in Internet Explorer. You can also save to your Knowledge Base from any other application (MS Word, email client, etc.). netXtract’s Knowledge Base (KB) Manager allows you to categorize, maintain and query your Knowledge Base. Selecting any entry saved from a web document returns you directly to that point in the original online document.
