    "abstract": "Datasets of online communication often take the form of contact sequences --\nordered lists contacts (where a contact is defined as a triple of a sender, a\nrecipient and a time). We propose measures of attractiveness and activity for\nsuch data sets and analyze these quantities for anonymized contact sequences\nfrom an Internet dating community. For this data set the attractiveness and\nactivity measures show broad power-law like distributions. Our attractiveness\nand activity measures are more strongly correlated in the real-world data than\nin our reference model. Effects that indirectly can make active users more\nattractive are discussed.",
