A Framework to Interpret Nonstandard Log-Linear Models

open access: yesAustrian Journal of Statistics, 2016
The formulation of log-linear models within the framework of Generalized Linear Models offers new possibilities in modeling categorical data. The resulting models are not restricted to the analysis of contingency tables in terms of ordinary hierarchical ...

Question classification with log-linear models

open access: yesProceedings of the 29th annual international ACM SIGIR conference on Research and development in information retrieval, 2006
Question classification has become a crucial step in modern question answering systems. Previous work has demonstrated the effectiveness of statistical machine learning approaches to this problem. This paper presents a new approach to building a question classifier using log-linear models.
