Improving context-aware query classification via adaptive self-training

Minmin Chen, Jian-Tao Sun, Xiaochuan Ni, Yixin Chen
2011 Proceedings of the 20th ACM international conference on Information and knowledge management - CIKM '11  
On the other hand, search contexts embedded in query sessions and unlabeled queries free on the web have not been fully utilized in most query classification systems.  ...  In this work, we leverage these information to improve query classification accuracy. We first incorporate search contexts into our framework using a Conditional Random Field (CRF) model.  ...  Motivated by these observations, we propose to build a semi-supervised context-aware query classification framework that takes advantage of both search contexts and unlabeled query sessions to improve  ...

2010 Proceedings of the third workshop on Exploiting semantic annotations in information retrieval - ESAIR '10  
The interpretations range from the traditional bag-of-words interpretation to more context-and semantic-aware interpretations.  ...  We introduce a query rating scheme that identifies the possible interpretations which can be assigned to a semantic query.  ...  [4] , with more terms, classifications and relationships. However, each retrieval system or retrieval process need not necessarily be aware of the semantic knowledge contained in each query.  ...

Task-aware query recommendation

Henry Feild, James Allan
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
We analyze the effects on query recommendation performance of using contexts consisting of only on-task queries, only off-task queries, and a mix of the two.  ...  We focus on two important classes of queries that make up search contexts: those that address the same information need as the reference query (on-task queries), and those that do not (off-task queries  ...  While previous work has considered task-aware query recommendation over logged user data, we are not aware of any work that systematically explores the effects of on-task, off-task, and mixed contexts  ...
