About


Network Science Lab is a group of people working on various aspects of network science, starting from spreading processes (information diffusion, influence spread, opinion formation, virus spread, etc.), through interacting spreading processes, seed selection (e.g. for influence maximisation, for “vaccination”, etc.), spreading velocity (e.g. seed distribution, process control etc.), community detection and evolution, social learning and cognitive processes, network control, streaming scenarios (including embeddings), and ending on computational social science. You can meet us at most of the top conferences on complex networks and social informatics, e.g., NetSci, NetSciX, IC2S2, ASONAM, SocInfo etc.

Data


  1. Jankowski, J., Michalski, R., Bródka, P. (2017). A multilayer network dataset of interaction and influence spreading in a virtual world. Scientific Data, 4, Article number: 170144, Data at Harvard Dataverse.
    Presented data contains the record of five spreading campaigns that occurred in a virtual world platform. During these campaigns, users were distributing the avatars between each other. The processes were either incentivized or not incentivized, and varying in time and range. The campaign data is accompanied by the events that can be used to build a multilayer network in order to be able to place these campaigns in a wider context (friendships, messages, transactions, etc.).

    History of internal e-mail communication (sender, recipient, datetime) between employees of a mid-sized manufacturing company. Multiple recipients of the same e-mail (To, CC, BCC) are represented as separate rows without distinguishing the recipient type. In this version apart from the communication metadata the organizational structure of the company is published (who reports to whom). The period covered are nine full months of 2010 starting from 2010-01-01 to 2010-09-30 (event dates in local time).

    The dataset contains Bitcoin addresses that have been identified and belong to one of particular categories: mining pools, miners, coinjoin services, gambling services, exchanges, other services - 8,008 addresses in total. The assignment of labels comes from two sources: plausible assumptions and external services and is not guaranteed to be error prone. These labels have been used for training and validating the performance of machine learning algorithms for discovering the types of addresses.
