Open Source Report Generator

I need an application that will perform open source research based upon a specified topic. Currently, search engines take keywords, phrases, etc and only return links to websites that have information related to the search terms. My idea is to have an application that is able to go to the next step beyond just returning URLs. For example, When a user specifies a search term/phrase the application actually returns a small report that is created from the various open sources and websites. Application Requirements: 1. Target Platform: Open for discussion. Could be HTML/browser with underlying code, or iPad app, or standalone executable for PC, or ?? 2. Input from user via keyboard: Topic of interest (consisting of 1 to 10 keywords) 3. Output from application: Plain text report, 500-1000 words in length. The report should be grammatically correct, and not simply cutting text from sources and randomly pasting them together. Then goal is to provide some paragraphs of text that give the user highlights/introduction to their specified topic.
