***** To join INSNA, visit http://www.insna.org ***** Is there any way of normalizing tie strength in the literature? If one defines tie strength between A and B as the number of times A and B have seen each other, then tie strengths (for the whole social network) are not comparable. To see why, consider that A and B have met four times. Those four times entail completely different meanings in different situations - for instance, they would reflect either an absent tie (if A and B are jet setters and go out a lot) or a strong tie (if they are homebodies and rarely go out). Also, if one normalizes the strength on A->B based on A's total number of encounters, then one should choose a threshold that differentiates strong ties from weak ties, and this begs the question of how to choose that threshold :-) Daniele. http://www.cs.ucl.ac.uk/staff/d.quercia/ group blog: http://mobblog.cs.ucl.ac.uk/ (join us!) _____________________________________________________________________ SOCNET is a service of INSNA, the professional association for social network researchers (http://www.insna.org).
