Freestyle vs. Boolean: A comparison of partial and exact match retrieval systems

Lee Anne H. Paris, Helen R. Tibbo
1998 Information Processing & Management  
Further study and analysis are needed to determine which elements of a query make it best suited for partial match or exact match retrieval.  ...  Although the Boolean searches had better results more often than the Freestyle searches, neither mechanism demonstrated superior performance for every query.  ...  These formulations, along with their levels of recall, precision, and efficiency, are the basis of comparison for the present study.  ...

Automatically capturing source code context of NL-queries for software maintenance and reuse

Emily Hill, Lori Pollock, K. Vijay-Shanker
2009 2009 IEEE 31st International Conference on Software Engineering  
In this paper, we present a novel approach that automatically extracts natural language phrases from source code identifiers and categorizes the phrases and search results in a hierarchy.  ...  Existing static code search techniques using natural language queries provide little support to help developers determine whether search results are relevant, and few recommend alternative words to help  ...  The authors would like to thank Giriprasad Sridhara, Amy Siu, Haley Boyd, Oana Tudor, and Keith Trnka for their useful help and comments on this paper.  ...

Discovering Non-taxonomic Relations from the Web [chapter]

David Sánchez, Antonio Moreno
2006 Lecture Notes in Computer Science  
We also discuss how the obtained relationships may be automatically evaluated, using relatedness measures based on WordNet.  ...  We present an automatic and unsupervised methodology for extracting non-taxonomically related concepts and labelling relationships, using the whole Web as learning corpus.  ...  In our case, bootstrapping is used to constrain the search process contextualizing the queries formulated to the search engine in order to obtain appropriate corpus of documents and web-scale statistics  ...

An end user evaluation of query formulation and results review tools in three medical meta-search engines

Gondy Leroy, Jennifer Xu, Wingyan Chung, Shauna Eggers, Hsinchun Chen
2007 International Journal of Medical Informatics  
Fewer searches were needed and more documents were found per search when both query reformulation and result review tools dynamically adjust to the user query.  ...  The query reformulation tool that provided a long list of keywords, dynamically adjusted to the user query, was used most often and led to more subtopics.  ...  Research questions We are interested in finding out if support tools requiring more or less user effort to use and understand will lead to different levels of spontaneous use, effectiveness and efficiency  ...

Our proposed algorithm first identifies several query-related semantic clusters based on a key phrases extraction algorithm originally proposed for clustering general Web search results.  ...  In this paper, we propose, IGroup, an efficient and effective algorithm that organizes Web image search results into clusters.  ...  The link information is also used in [7] . It first used block-level link analysis to construct an image graph.  ...
