Query Formulation for Answer Projection [chapter]

Gilad Mishne, Maarten de Rijke
2005 Lecture Notes in Computer Science  
We examine the effects of various query modifications on the problem of answer projection -the task of retrieving documents that support a given answer to a question.  ...  We compare different techniques such as phrase searches and term weighting, and show that some models achieve significant improvements over unmodified queries.  ...  Conclusions We address the answer projection task in Question Answering as a query formulation problem.  ...

A projection box cannot be yellow, because if there is a feasible query that has the corresponding projection atom in the SELECT clause, then the query formulated by removing this atom is also feasible  ...  However, it cannot answer the query "return all computers with 1GB of RAM".  ...

Exploratory querying of extended knowledge graphs

Mohamed Yahya, Klaus Berberich, Maya Ramanath, Gerhard Weikum
2016 Proceedings of the VLDB Endowment  
TriniT supports query relaxation rules that are invoked to allow for relevant answers which are not found otherwise.  ...  The query language, relaxation methods, and answer ranking are extended appropriately. The demo shows automatic query relaxation and has support for interactively adding user-customized relaxations.  ...  Answers are returned in the form of variable bindings for projection variables. Advanced users can explore additional options.  ...

Semantic Retrieval Approach to Factoid Question Answering for Bulgarian [chapter]

Stanislav Peshterliev, Ivan Koychev
2011 Advances in Intelligent and Soft Computing  
Search engines attempt to retrieve the most relevant documents for a given query, but still require users to look for the exact answer.  ...  Question Answering (Q&A) systems go one step further by trying to answer users' questions posed in natural language.  ...  We are grateful to Kiril Simov and Petya Osenova for providing us with the data from Bultreebank project, and their help with references and suggestion.  ...

Query Morphing: A Proximity-Based Approach for Data Exploration [chapter]

Jay Patel, Vikram Singh
2018 From Natural to Artificial Intelligence - Algorithms and Applications  
Fundamental understanding of complex schema and content is necessary for formulating data retrieval request.  ...  We proposed 'Query morphing', an approach for query reformulation based on data exploration. Identified design concerns and implementation constraints are also discussed for the proposed approach.  ...  Many other formulation techniques for query construction such as locate minimal project join queries, discovering query approach [34] etc. are developed to answer query formulation similar to example  ...

Data-Intensive Question Answering

Eric Brill, Jimmy J. Lin, Michele Banko, Susan T. Dumais, Andrew Y. Ng
2001 Text Retrieval Conference  
First, the occurrence of multiple linguistic formulations of the same answer increases the chances of being able to find an answer that occurs within the context of a simple pattern matching the query.  ...  Answer Redundancy and Question Answering Answer redundancy (multiple, differently phrased, answer occurrences) serves two purposes for our task of question answering.  ...  We believe that data redundancy is a readily available and valuable resource that should be exploited for question answering in much the same way as linguistic resources often are.  ...

F-metric: a WWW-based framework for intelligent formulation and analysis of metric queries

C.L Chee, S Jarzabek, R Paul
1998 Journal of Systems and Software  
We de®ned a project management query language (PMQL for short), based on concepts of an extended Entity-Relationship model, which we used to formulate project queries at a conceptual level.  ...  While many organizations utilize software metrics to analyze project issues and answer management queries, the manner in which such queries are answered varies from organization to organization.  ...  Then, we de®ne a Project Management Query Language (PMQL for short) in which we can formulate project queries.  ...
