Domain specific syntax based approach for text classification in machine learning context

摘要

Due to the vast amount of data, searching and obtaining relevant information on the web is a challenging task. Despite that a broad range of classification techniques have been proposed to improve the information retrieval methods, many difficulties are still present because of the continuous increase in the amount of web contents, as well as its diversity. In this paper, we propose a method that automatically identifies and classifies user queries by using a domain specific syntax approach — this approach is based on the syntactical pattern of each type of search query. A framework is developed to test the performance of the proposed method. Experimental results show that our approach leads to accurate identification of different query types.
