Claim One:
1. A method for contextual analysis, comprising: obtaining, via a computer system configured with a software package for contextual analysis, representative communications associated with a sociopolitical concept; assessing, via the software package for contextual analysis, the representative communications in order to form a contextual assessment; and providing, to a user of the software package for contextual analysis, the contextual assessment; wherein the assessing comprises perspective mining utilizing a logistic regression of the form: min x ⁢ ∑ i = 1 m ⁢ ⁢ w i ⁢ log ⁡ ( 1 + exp ⁡ ( - y i ⁡ ( x T ⁢ a i + c ) ) ) + λ ⁢  x  1 wherein in is the number of documents in the representative communications; x T is s the transpose of x; c is the intercept used in the logistic regression; a i is the vector representation of the i th document the representative communications; w i is the weight assigned to the i th document (w i =1/m by default); A=[a 1 , a 2 ,. .. , a m ] is a document keyword matrix; y i is the polarity of each document based upon the scale polarity of the actor that the document belongs to; the unknown x 1 , the j-th element of x, is the weight for each keyword; λ>0 is a regularization parameter that controls the sparsity of the solution; and |x| 1 =Σ|x i | is 1-norm of the x vector.
