Keyword query cleaning using hidden Markov models

Content Provider ACM Digital Library
Author Pu, Ken Q.
Abstract In this paper, we consider the problem of keyword query cleaning for structured databases from a probabilistic approach. Keyword query cleaning consists of rewriting the user query, segmenting the keywords, matching each segment to database items, and finally tagging the segments by their meta-data information. We present an efficient and robust solution using Hidden Markov Models (HMM). By modeling user keyword queries using a generative probabilistic HMM-based model, we construct a HMM from the user specified keyword query (and the database instance). The optimal statistical keyword cleaning is computed as the most likely path of the constructed HMM. Furthermore, we demonstrate how the optimal HMM-based keyword cleaning algorithm can be generalized to compute a stream of clean queries ranked from the most likely clean query to the least likely clean query. Finally, we present the implementation of the proposed system and its preliminary performance.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
