In this expansion process, terms in the top-returned documents is weighted using a particular DFR term weighting model. Currently, Terrier deploys the Bo1 (Bose-einstein 1), Bo2 (Bose-einstein 2) and KL (Kullback-leibler) term weighting model S. The DFR term weighting models follow a parameter-free a

other linked lists below.Because a pointer to the contents of a linked list is stored separately, and the adjacent nodes may be modified, sometimes the first node may be deleted or a new node is added before. This is the time to modify the pointer to the first node. One convenient way to eliminate this particular situation is to store a virtual node that will never be deleted or moved before the last node, before the first node, forming a circular list below. The node after this virtual node is

I have talked a lot about the methods for setting wireless routes. Today I will mainly explain how to configure wireless network parameters for PSP and some configuration problems. I hope this will help you. With the development of wireless routing technology, more and more devices have the function of connecting to the wireless network to facilitate resource sharing and system upgrade.
A few days ago, I once introduced to readers of IT168 how to add wireless wings to
