1. Title of Database: Buzz prediction on Tom's Hardware - Absolute Labeling - Threshold Sigma equals 500
2. Sources:
-- Creators :
François Kawala (1,2) and
Ahlame Douzal (1) and
Eric Gaussier (1) and
Eustache Diemert (2)
-- Institutions :
(1) Université Joseph Fourier (Grenoble I)
Laboratoire d'informatique de Grenoble (LIG)
(2) BestofMedia Group
-- Donor: BestofMedia (ediemert@bestofmedia.com)
-- Date: May, 2013
3. Past Usage:
-- References :
Predicting Buzz Magnitude in Social Media (in submission (ECML-PKDD 13))
-- Predicted attribute :
Buzz. This attribute is boolean: 1 meaning `buzz observed', 0 meaning
`no buzz observed'. It is stored is the rightmost column.
-- Study results :
The results achieved indicates that the task is trivial. Indeed, using random forest yields a F-1 score of around 0.97 for the Buzz class, when the data is scaled and normalized. First order discrete difference over features may also be considered as additional features.
4. Relevant Information Paragraph:
-- Observations :
Each instance covers height weeks of observation for a specific topic (eg.
overclocking...). Considering the couple weeks following this initial
observation; If there is at least 500 additional active discussions by
day (on average, with respect to the initial observation) then, the
predicted attribute Buzz is True.
Observations are Independent and identically distributed.
5. Number of Instances
-- Total number of instances : 7905
6. Number of Attributes
-- Total number of attributes : 96.
-- Time representation :
Each instance is described by 96 features, those describe the evolution
of 12 `primary features' through time. Hence each feature name is
postfixed with the relative time of observation. For instance, the value
of the feature `Nb_Active_Discussion' at time t is given in
'Nb_Active_Discussion_t'.
