Dear Madhawa, Thank you for your interest in the proposals. The current tasks we proposed refer to the classification and quantification regardless of the topic. This can be used in a larger context where the topic is not specified, or not unique, in which case we will need to identify the topic(s). Therefore, a topic detector would be a good idea to implement, in order to complement this.
As for the Document Categorizer, it is a general purpose component with basic features (n-gram, bag of words, etc.). It is basically used for the classification of texts into a set of classes defined by the user, whether they are sentiment classes or other. However it doesn't perform well for this purpose. Furthermore, the sentiment analysis component would not just perform the naive classification but also additional tasks (e.g., quantification) and implement more specific and sophisticated approaches. Please share your thoughts.
