In particular, when two proteins are distantly related, there is no good indicator to reliably assess whether they are homologous or not. Figure 1 shows the number of unique orthologous pairs between the yeast Saccharomyces cerevisiae and Arabidopsis thaliana acquired from the Website of Clusters of Orthologous Groups of proteins (COGs) [ 37].
Defenders have responded by using machine learning techniques to automatically classify malicious websites [4] and to cluster website copies together [5]-[8].
Figure 5 groups the ten largest clusters from the fake escrow dataset and plots the date at which each website in the cluster first appears.
For instance, the first reported website in one cluster of 18 fake escrow websites appeared on 2 February 2013, while the last one occurred on 7 May 2013.
Survival analysis takes into account 'censored' data points, i.e., when the final website in the cluster is reported near the end of the study.
Internally displaced person (IDP) camp sites with medical clinics and local health facilities in Port-au-Prince were identified by lists provided by NGOs, local contacts, or on the health cluster website http://www.oneresponse.info.info
Current activities conducted by ACRM, such as continuous collection and dissemination of knowledge through seminars and field trips, and the accessibility of a cluster website, should be regarded as valuable components.
The NCEH cancer cluster website (http://www.cdc.gov/nceh/clusters; CDC 2004) was developed and designed to support the inquiry system and to facilitate information sharing among federal, state, and local agencies; it provides the cornerstone for the cancer cluster inquiry system.
The exome.tigem.it website uses a cluster with 8 computing nodes equipped with dual Xeon E5-2670 for a total amount of 128 computing cores and 376GB of RAM.
A number of researchers have applied machine learning methods to cluster websites created by cybercriminals.
The Logistics Clusters website [41] has a good archive containing 11 types of documents.
