Digital Directions: The Semantic Web
• Knovel. Knovel provides semantically structured collections of engineering and technical content, including text, charts and tables. This allows the information contained in articles to be queried, as one would query a database. Technical researchers can find answers contained in large bodies of content with great efficiency. For example, a technical researcher could submit a query to find studies that address polymers with a specific tensile strength at a given temperature range. This is tremendously more efficient than simply putting a search engine on top of a collection of thousands of journal articles. In the context of the cost of an engineer’s time (and the time he saves on research), the economic value is enormous.
