As you examine the literature references for an association network, you may find it useful to delete certain sentences -- or entire references -- from the network. This could be done, for example, for references that you consider not as credible or not providing strong support for the putative network.
You can delete a sentence from a displayed list of sentences by right-mouse clicking and selecting Delete Sentence from the menu that pops up (see figure below).
Note that when you delete a sentence, all copies of that sentence are deleted from the system. (Note also that in this version of Agilent Literature Search, any sentence panels showing the deleted sentence are not automatically updated to reflect the deletion of that sentence. However, any sentence panels that are displayed after the deletion of the sentence will correctly reflect the deletion of that sentence, i.e. they will not show that sentence).
Agilent Literature Search associates each sentence with a "source". The source is the reference document in which that sentence appears. There can be multiple sentences for a source. When all sentences associated with a source are deleted, then that source is automatically deleted. Sources and sentences are, in turn, associated with Cytoscape edges. When all sources associated with an edge are deleted, then Agilent Literature Search will delete that edge from the system. When the edge is deleted, any nodes for that edge are checked to see what edges they are connected to. If the deleted edge is the only edge that a node is connected to, then that node is deleted, as well.
You can delete an entire reference from a network by right-mouse clicking on an entry in the Query Matches panel and selecting Delete Match from the menu that pops up (see figure below).
When all references associated with an edge are deleted, then Agilent Literature Search will delete that edge from the system. When the edge is deleted, any nodes for that edge are checked to see what edges they are connected to. If the deleted edge is the only edge that a node is connected to, then that node is deleted, as well.
