    hi  @lionelderkrikor

    thanke you  for your reply and attention

    it work for single user but in my dataset i have a set of users that each user send a set of tweets... for calculation this interval for each user what should i do???

    Hi again @ramzanzadeh72,

     

    Could you share your dataset(s) and process to better understand your problem.

    @lionelderkrikor

    i share part of my dataset that user_id show id of user that send tweet and create_at show the time that tweet send by user... in this dataset we have 3 user and each user send multiple tweet that create_at show the send time of tweet.

    so we should first sort the tweets send by each user base on create_time and then calculate interval of sequential tweets of each user.

    @ramzanzadeh72,

     

    We should sort the dataset by user_id and then, in deed, you're right, by created_at. For this operation, I used

    the Sort (advanced) operator from the Jackhammer extension (to install from the marketplace).

    Here the new process : 

    <?xml version="1.0" encoding="UTF-8"?><process version="8.2.000">

    <parameter key="column_separators" value=","/>
    <parameter key="first_row_as_names" value="false"/>
    <list key="annotations">

    </list>
    <parameter key="encoding" value="windows-1252"/>
    <list key="data_set_meta_data_information">
    <parameter key="0" value="created_at.true.polynominal.attribute"/>
    <parameter key="1" value="user_id.true.real.attribute"/>
    </list>
    </operator>
    <operator activated="true" class="nominal_to_date" compatibility="8.2.000" expanded="true" height="82" name="Nominal to Date" width="90" x="179" y="34">

    <parameter key="date_type" value="date_time"/>
    <parameter key="date_format" value="EEE MMM dd HH:mm:ss +0000 yyyy"/>
    </operator>
    <operator activated="true" class="rmx_toolkit:sort_advanced" compatibility="2.1.784" expanded="true" height="82" name="Sort (Advanced)" width="90" x="380" y="34">
    <parameter key="primary_sort_attribute" value="user_id"/>
    <list key="additional_sort_attributes">
    <parameter key="created_at" value="increasing"/>
    </list>
    </operator>
    <operator activated="true" class="series:lag_series" compatibility="7.4.000" expanded="true" height="82" name="Lag Series" width="90" x="514" y="34">
    <list key="attributes">
    <parameter key="created_at" value="1"/>
    </list>
    </operator>
    <operator activated="true" class="generate_attributes" compatibility="8.2.000" expanded="true" height="82" name="Generate Attributes (2)" width="90" x="648" y="34">
    <list key="function_descriptions">
    <parameter key="tweet_interval" value="date_diff([created_at-1],created_at)"/>
    </list>
    </operator>
    <connect from_op="Read CSV" from_port="output" to_op="Nominal to Date" to_port="example set input"/>
    <connect from_op="Nominal to Date" from_port="example set output" to_op="Sort (Advanced)" to_port="example set input"/>
    <connect from_op="Sort (Advanced)" from_port="example set output" to_op="Lag Series" to_port="example set input"/>
    <connect from_op="Lag Series" from_port="example set output" to_op="Generate Attributes (2)" to_port="example set input"/>
    <connect from_op="Generate Attributes (2)" from_port="example set output" to_port="result 1"/>
    <portSpacing port="source_input 1" spacing="0"/>
    <portSpacing port="sink_result 1" spacing="0"/>
    <portSpacing port="sink_result 2" spacing="0"/>
    </process>
    </operator>
    </process>

    You can note that the interval between tweets is in milliseconds. You can customize the formula

    in the last Generate Attributes operator to convert the interval in seconds, minutes, hours, days etc.

    @lionelderkrikor
    Thanke you... thats right....
    But I have another question... how can I calculate entropy for these intervals for each user???
