A new approach for evaluating query expansion

Tonya Custis, Khalid Al-Kofahi
2007 Proceedings of the 30th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '07  
In this paper, we propose a new approach for evaluating query expansion techniques.  ...  Query-document term mismatch, whether partial or total, is a fact that must be dealt with by IR systems. Query Expansion (QE) is one method for dealing with term mismatch.  ...  Our approach is to introduce querydocument term mismatch into a corpus in a controlled manner and then measure the performance of IR systems as the degree of term mismatch changes.  ...

Exploring Document Expansion for Argument Retrieval

Alina Mailach, Denise Arnold, Stefan Eysoldt, Simon Kleine
2021 Conference and Labs of the Evaluation Forum  
This notebook documents our attempt to improve argument retrieval using expansion methods for documents as a contribution to Touché@CLEF 2021 as team Hua Mulan.  ...  Before runtime we expand arguments by predicting queries and hallucinating arguments using Transformer architectures and a more computational efficient approach based on TF-IDF.  ...  Document Expansion A gap that many retrieval approaches try to bridge is the issue of mismatch between terms in a query and terms in documents relevant to this query.  ...

Advances in IR Query Expansion

2018 International Journal of Advanced Research in Computer Science and Software Engineering  
Due to huge variation in framing a query by the individuals, matching of the terms with the document to be searched are facing many challenges.  ...  Researchers have worked on problem of identifying the correct essence of the user query by adding additional useful terms. They are currently working on this kind of Query Expansion (QE).  ...  In manually based query expansion approach [9] , the user is solely responsible for selecting additional term for expanding the query.  ...

Query expansion for microblog retrieval

Ayan Bandyopadhyay, Kripabandhu Ghosh, Prasenjit Majumder, Mandar Mitra
2012 International Journal of Web Science  
In this preliminary study, we explore standard query expansion approaches as a way to address this problem. Since the tweets are short, we use external corpora as a source for query expansion terms.  ...  Since many of the TREC topics were oriented towards the news genre, we also tried restricting the GSA to a news site (BBC) in the hope that it would be a cleaner, less noisy source for expansion terms.  ...  [2] also suggested a ranking method for news documents in which recency plays a major part.  ...

Automatic term mismatch diagnosis for selective query expansion

Le Zhao, Jamie Callan
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
For a given topic, the proportion of relevant documents that do not contain a term measures the probability for the term to mismatch relevant documents, or the term mismatch probability.  ...  Typically, it is used in probabilistic retrieval models to provide query dependent term weights. This paper develops a new use: Automatic diagnosis of term mismatch.  ...  We thank Chengtao Wen, Grace Hui Yang, Jin Young Kim, Charlie Clarke, Gordon Cormack and NIST for helpful discussions, feedback and access to data.  ...

Query expansion by mining user logs

Hang Cui, Ji-Rong Wen, Jian-Yun Nie, Wei-Ying Ma
2003 IEEE Transactions on Knowledge and Data Engineering  
In this study, we propose a new method for query expansion based on user interactions recorded in user logs.  ...  The central idea is to extract correlations between query terms and document terms by analyzing user logs. These correlations are then used to select high-quality expansion terms for new queries.  ...  For new queries, high-quality expansion terms can be selected from the document space on the basis of the extracted correlations.  ...

Sensual Semantic Analysis for Effective Query Expansion

Muhammad Ahsan Raza, M. Rahmah, A. Noraziah, Mahmood Ashraf
2018 International Journal of Advanced Computer Science and Applications
