Lecture webcasts are readily available on the Internet. These include class lectures, research seminars and product demonstrations. Webcasts routinely combine presentation slides with either a synchronized audio stream (i.e., podcast) or an audio/video stream. Conventional web search engines retrieve this content if you include "webcast" or "lecture" among your search terms, or search a website that specifically organizes lecture content. But users, particularly students, want to find the place in a lecture when an instructor covers a specific topic. Answering these queries requires a search engine that can search within the webcast to identify important keywords. TalkMiner aggregates and indexes lecture videos available across the internet. The system processes RSS feeds from a variety of sites to collect lecture videos. The system automatically processes the video to generate metadata describing each talk including the video frames that contain slides, their time offsets, and the text recovered from those frames by optical character recognition. TalkMiner does not maintain a copy of the original videos. When a user plays a lecture, the video is played from the original website on which the lecture video is hosted. As a result, storage requirements for TalkMiner are modest.

"Being able to solve everyday complex problems through communication and cooporation with others are the skills that students need to learn and practice to prepare for the future. Communicating effectively and efficiently with diverse audiences and solving everyday problems are important in a society that is moving at a rapid pace in a Global Market. The ability to solve everyday complex problems is an important and necessary skill for students today. Problem based learning (PBL) provides a learning environment students require to resolve everyday problems while applying previous and learning new knowledge. Cooperative learning, as a part of PBL, allows students the opportunity to communicate ideas and knowledege. As a teacher it is also important to communicate effectively with students to guide the learning process as well as model how to question and reason through a problem. The web-enhanced 3 part seminar series is designed to review and apply the basics of PBL to allow you to create a PBL unit to use within your own classroom."
