This notebook explores how collaborative relationships form between mailing list participants over time.

The hypothesis, loosely put, is that early exchanges are indicators of growing relationships or trust that should be reflected in information flow at later times.

In particular we are interested in who replied to who at each time. Recall that this is an open mailing list--everybody potentially reads each message. A response from A to B is an indication that A read B's original message. Therefore, a response indicates not just a single message from A to B, but an exchange from B to A and back again.

Below we modify our data to see who replied to whom.





In [8]:



    


messages = arx.data[['From']]

responses = arx.data[arx.data['In-Reply-To'] > 0][['From','Date','In-Reply-To']]

exchanges = pd.merge(messages,responses,how='inner',right_on='In-Reply-To',left_index=True,suffixes=['_original','_response'])

5579 rows × 2 columns

The next step is to create a DataFrame that for each pair A and B:

  • The duration of time between the first reply between that pair and the last.
  • The total number of replies from A to B, $r_{AB}$, and from B to A, $r_{BA}$.
  • The reciprocity of the conversation $min(r_{AB},r_{BA})/max(r_{AB},r_{BA})$

Using the exchanges data frame we can use the functions in twopeople.py to calculate the above quantities. The cell below gives a sample output for calculating duration, number of replies, and reciprocity for two specific contributers.





In [10]:



    


twoppl.duration(exchanges, "oliphant at ee.byu.edu (Travis Oliphant)", "rossini at blindglobe.net (A.J. Rossini)"  )
twoppl.panda_pair(exchanges, "oliphant at ee.byu.edu (Travis Oliphant)", "rossini at blindglobe.net (A.J. Rossini)"  )



    


















    
Out[10]:










  
    

      
      A
      B
      duration
      num_replies
      reciprocity

      465 days 14:33:48
       4
       0.333333

The "duration" column gives us a datetime data structure so we must be careful later on when extracting information from this column.





In [11]:



    


twoppl.duration(exchanges, "oliphant at ee.byu.edu (Travis Oliphant)", "rossini at blindglobe.net (A.J. Rossini)"  )



    


















    
Out[11]:








Timedelta('465 days 14:33:48')

Now let's create a dataframe that consists of these three quantities (duration, number of replies, and reciprocity) for each pair of contributers who interacted.

To get all the unique pairs we can use the unique_pairs function in twopeople.py. This willl give us all pairs between any two individuals who had some degree of interation.

Note: The unique pairs we get back do not include reversed pairs. For example, if one of the pairs was ("Bob", "Mary"), we would not have ("Mary", "Bob") in our output.





In [12]:



    


pairs = twoppl.unique_pairs(exchanges)
pairs



    


















    
Out[12]:

4019 rows × 5 columns

The printed values below display the counts associated for a given number of replies.

We can see that many of the interactions have a relatively small amount of replies. One possible explanation for this large amount may be having many interactions that are merely a follow-up or question followed by a thank you response (we can explore this further by parsing the message bodies in arx.data but for now we will just speculate).

To get a better idea of what's going on for larger values, let's look at the rows that have number of replies greater than 5.

greaterThanFive = allpairs[allpairs['num_replies'] > 5]['num_replies']
counts = greaterThanFive.value_counts()
counts.plot()

The graph seems to follow a power law which is expected for this type of data.

Now let's see if we can find any patters between the number of replies and reciprocity. Intuitively, we would expect that the number of replies be positively associated with reciprocity but let's see...

We will first look at the data for which the number of replies is greater than 5 to possibly get rid of some noise (later on we will explore the data without removing these entries).

Below we divided reciprocity and number of replies into completely arbitrary bins as shown below. Hopefully, this will make it easier to see patters between these two variables as they have quite a bit of noise.

(The genId and genNumReplies functions just give each entry a corresponding label for graphing purposes later on. These labels are based on which bin a given entry falls under)





In [16]:



    


#Completely arbitrary bins

#Group A reciprocity between (0, .25]
#Group B reciprocity between (.25, .5] 
#Group C reciprocity between (.5, .75]  
#Group D reciprocity between (.75, 1.00]

#"low" number of replies less than or equal to 10
#"moderate" number of replies between 10 and 20
#"high" replies greater than 20 replies 

def genId(num):
    if num <= .25:
        return 'A.(0, .25]'
    if num <= .5:
        return "B.(.25, .5]"
    if num <= .75:
        return "C.(.5, .75]"
    return "D.(.75, 1.00]"

def genNumReplies(num):
    if num <= 10:
        return 'a.low'
    if num <= 20:
        return "b.moderate"
    return "c.high"

The following lines generate a data frame that contains three columns: 1) Number of replies 2) Id corresponding to replies bin 3) Id corresponding to reciprocity bin

(The extra letters such as the a in "a.low" are just used so that pandas orders the columns in the way we want)

Since each reciprocity group has a different amount of counts, let's normalize the counts to get a better picture of what's going on.

We will first normzalize column-wise, that is for say column A.[0,.25] we will sum the total number of responses and get the relative proportions for the replies bins.

We see that at the very extremes, namely reciprocity between 0-.25 and reciprocity between .75-1.0, there are some clear differences; reciprocity seems to be positively associated with the number of replies as we had initially expected.

On the other hand, the bin for reciprocity between .25-.5 weakens this association as this bin seems as if it should swap positions with bin A. However, since the bin widths we chose were completely arbitrary it may explain this paradox.

The fact that the extremes seem to follow our expectations is quite interesting; it provides some evidence that if we choose our bin sizes appropriately, we can perhaps get a nice positive association.

Now will do the normalization by row. This will give us the relative proportion of some bin for number of replies is distributed across the bins for reciprocity.

Since we actually have the bodies of each message, we will now procceed by seeing if there are any patterns between the type of messages sent and reciprocity, duration, and the number of replies.

As a very rough measure, we have created a function calMessageLen that calculates the length of a given message.

def calMessageLen(message):
    if message == None:
        return 0
