The problem: Abundance, Relevance and Time
Scientists look forward to discovering the emergent knowledge or Research Front
Documents cited more frequently
(Shibata et al., 2009; Upham & Small, 2010)
Scientists tend to mention the most recent documents to gather the more updated
knowledge:
Immediacy factor (Price, 1965).
The number of scientific documents doubles every 1.8 years
(Kleinberg, 1999; Wang, Song, & Barabási, 2013)
Abundance
Relevance vs Time What to read?
How to order the Reading?

Our model: (2)Bi-relational networks, (3) levels, (3) Fronts
2 directednetworks
3 Prestige based ranks
3 levels ofanalisyscombined
Backward front: Origin
Intermediary frontThe broker
Forward front : Destination

1est Innovation: Forward Front based on the whole structure
Abundance reduction
Prestige based using the whole structure of the forward network
Forward current front
Eigenvector Centrality is an energy diffusion vector in a steady state of energy, representing a ranking of documents where the knowledge (the diffused element) of the network is deposited (Rodriguez & Shinavier, 2010)
Take advantage of the acyclicalfeature

2nd Innovation Strategical Reading recommendation map
Relates forward and backward undestandingcurrent relevence
Classifies Communities
Gives a Reading recommended group and inside each 3 document level lists
Provides 3 levels of reduction

3nd Innovation: Asymmetric bow tie: 3 Fronts
The Intermediary Front is very small
Size of the Forward Front shorter than the Backward Front
Backward front: Origin
