Traditionally, KM was more often than not a top-down driven approach. For example, document taxonomies and knowledge sharing procedures were defined; identified experts shared their knowledge in defined communities.
Today, we can identify six strong trends that lead into new concepts of knowledge sharing and collaboration:
People are inherently curious for more based on their interest: a) Social media allows us to discover new content which is shared by our peers, friends, etc. b) Social computing empowers people to access information that is related to their interests and scope of work. These services support employees gain faster a deeper and broader expertise complementing classic (expensive) training. This open doors to informal and contextual learning; a more costs effective training.
The semantic web – aka Web 3.0 – is built on the idea that not only humans but also machines can understand information. Enterprises can benefit from semantic web services by defining company-wide meta-data on all forms of knowledge and improve coherence and consistency in classifying content which will lead to more accurate search results.
