Question classification using support vector machines

Abstract: Question classification is very important for question answering. This paper presents our research work on automatic question classification through machine learning approaches. We have experimented with five machine learning algorithms: Nearest Neighbors (NN), Naïve Bayes (NB), Decision Tree (DT), Sparse Network of Winnows (SNoW), and Support Vector Machines (SVM) using two kinds of features: bag-of-words and bag-ofngrams. The experiment results show that with only surface text features the SVM outperforms th… Show more

“…SVM has shown good performance for many natural language related applications, such as text classification (Joachims 2002), and has been used in multiple studies relating to question classification (Blooma et al 2008;Tamura, Takamura and Okumura 2005;Solorio et al 2004;Zhang and Lee 2003). Table 4 summarizes the performance of all the classifiers evaluated in our experiment.…”

“…NLP has investigated methods to categorize questions more accurately and appropriately (work such as Zhang and Lee (2003) discusses these concepts) in order to aid question classification. Additionally, numerous works surrounding the use and motivations of Q&A (e.g., Jeon et al (2010); Dearman and Truong (2010)) are still popular research areas.…”

“…Zhang and Lee (2003) employed tree kernel with a SVM classifier for question classification and reported 80.2% accuracy without the use of syntactic or semantic features. Li and Roth (2002) reported a hierarchical approach for question classification based on the SNoW learning architecture.…”
