Feature Extraction in Subject Classification of Text Documents in Polish
International Conference on Artificial Intelligence and Soft Computing, 2018In this work we evaluate two different methods for deriving features for a subject classification of text documents. The first method uses the standard Bag-of-Words (BoW) approach, which represents the documents with vectors of frequencies of selected terms appearing in the documents.

Adaptive subjective triggers for opinionated document retrieval
Proceedings of the Second ACM International Conference on Web Search and Data Mining, 2009This paper proposes a novel application of a statistical language model to opinionated document retrieval targeting weblogs (blogs). In particular, we explore the use of the trigger model---originally developed for incorporating distant word dependencies---in order to model the characteristics of personal opinions that cannot be properly modeled by ...

Structuring and Documenting Interactions with Subject-Matter Experts
Performance Improvement Quarterly, 2008We have developed interviewing techniques for knowledge elicitation based on (1) relevant research and techniques from the social sciences, (2) the nature of expertise, and (3) a desire to avoid reductive bias, one of the pitfalls associated with the acquisition of highly complex knowledge.

This suggests that the SuDoc scheme is inappropriate for topical questions.
