Restricted natural language based querying of clinical databases

Leila Safari, Jon D. Patrick
2014 Journal of Biomedical Informatics  
In this paper a generic translation algorithm is proposed to translate a restricted natural language query (RNLQ) to a standard query language like SQL (Structured Query Language).  ...  Results: It is easy to compose a RNLQ via CliniDAL's interface in which query terms are automatically mapped to the underlying data models of a Clinical Information System (CIS) with an accuracy of more  ...  We would also like to thank the University of Zanjan for financial support of the whole research period.  ...

Processing of natural language queries to a relational database

M. Samsonova, A. Pisarev, M. Blagov
2003 Bioinformatics  
The conceptual scheme is mapped formally onto the logical scheme. We applied the method to query the FlyEx database in natural language.  ...  Results: The method, based on a semantic approach, interprets grammatical and lexical units of a natural language into concepts of subject domain, which are given in a conceptual scheme.  ...  The authors are thankful to Alexander M. Samsonov for valuable discussions and comments, and Ekaterina Poustelnikova for help in conceptual scheme design.  ...

Semantic Analysis of Natural Language Queries for an Object Oriented Database

Bentamar Hemerelain, Hafida Belbachir
2010 Journal of Software Engineering and Applications  
This paper presents the semantic analysis of queries written in natural language (French) and dedicated to the object oriented data bases.  ...  Coherence rules and coherence constraints are introduced, to check the validity of the co-occurrence of two consecutive nouns in complex NG.  ...  A NLIDB allows users to input a query in a natural language such rather than in a formal query language and in conceptual terms particular to their understanding of the database application domain.  ...

Semantic Matching of Natural Language Web Queries [chapter]

Naouel Karam, Salima Benbernou, Mohand-Said Hacid, Michel Schneider
2004 Lecture Notes in Computer Science  
To deal with linguistic information when comparing description logic concepts, we propose a definition of subsumption that takes into account names similarity between concepts occurring in the descriptions  ...  In this paper, we propose a method to automatically rank documents returned by a search engine in the WWW with respect to a query.  ...  The novelty of the approach proposed in this paper is that it allows the user to express his query as a natural language description.  ...

Deriving database queries from logical forms by abductive definition expansion

Manny Rayner, Hiyan Alshawi
1992 Proceedings of the third conference on Applied natural language processing -  
The paper describes a principled approach to the problem of deriving database queries from logical forms produced by a general NL interface.  ...  The technical basis for the approach is that a "definition" of the form Head A Conditions ~ Body can be read procedurally as "Expand Head to Body if it occurs in an environment where Conditions can be  ...  We will assume here that the interface takes input in a natural language and produces a representation in some kind of enriched firstorder logic, and that the application is some kind of relational database  ...

A Natural-language-based Visual Query Approach of Uncertain Human Trajectories

Zhaosong Huang, Ye Zhao, Wei Chen, Shengjie Gao, Kejie Yu, Weixia Xu, Mingjie Tang, Minfeng Zhu, Mingliang Xu
2019 IEEE Transactions on Visualization and Computer Graphics  
In this paper, we propose a visual analytics approach that can extract spatial-temporal constraints from a textual sentence and support an effective query method over uncertain mobile trajectory data.  ...  It is built up on encoding massive, spatially uncertain trajectories by the semantic information of the POls and regions covered by them, and then storing the trajectory documents in text database with  ...  ACKNOWLEDGMENTS This work was supported in part by National Natural Science Foundation of China (U1609217, 61772456, 61761136020).

Evaluating the Usability of Natural Language Query Languages and Interfaces to Semantic Web Knowledge Bases

Esther Kaufmann, Abraham Bernstein
2010 Social Science Research Network  
The results of the study reveal a clear preference for full natural language query sentences with a limited set of sentence beginnings over keywords or formal query languages.  ...  The need to make the contents of the Semantic Web accessible to end-users becomes increasingly pressing as the amount of information stored in ontology-based knowledge bases steadily increases.  ...  The authors would like to thank Ray Mooney and his group from the University of Texas at Austin for having generously supplied the data set, on which the usability study was based (http: //www.cs.utexas.edu  ...
