1. The document discusses how semantic search and the Semantic Web can change the way we work by enabling more precise search results through understanding relationships between data. 2. Examples of applications of semantic technologies include moderated/faceted search, navigation/browsing, recommender systems, question answering machines, collecting distributed information and sentiment analysis. 3. The Semantic Web aims to publish facts on the web in the form of "triples" using identifiers so relationships between data can be explicitly represented.
