A new approach for evaluating query expansion
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. ...

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
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. ...

Following this observation, we propose a simple method that predicts which queries will be issued for a given document and then expands it with those predictions with a vanilla sequence-to-sequence model ...
One technique to improve the retrieval effectiveness of a search engine is to expand documents with terms that are related or representative of the documents' content.From the perspective of a question ...

Automatic term mismatch diagnosis for selective query expansion
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. ...

Query expansion by mining user logs
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. ...

Proceedings of the 22nd Australasian Document Computing Symposium on - ADCS 2017
ery expansion is used to overcome the vocabulary mismatch between the documents and queries, but it can lead to query dri . ...
Instead of appending the new terms directly to the original query, we merge the term frequencies with the original query term. is reduces the impact of spurious expansion terms being over represented in ...

For good automatic transcriptions (25% word error rate), retrieval effectiveness with document expansion is indistinguishable from retrieval from human transcriptions. ...
We are also thankful to NIST for making these transcriptions available to us. ...

Sensual Semantic Analysis for Effective Query Expansion
2018
International Journal of Advanced Computer Science and Applications
