An intelligent approach to handling imperfect information in concept-based natural language queries

Vesper Owei
2002 ACM Transactions on Information Systems  
In either case, the effect could be disastrous for organizations. In this article, therefore, approaches are developed for handling imperfection in concept-based natural language queries.  ...  It is therefore imperative to study these problems in concept-based query languages, with a view to prescribing formal approaches to dealing with the problems.  ...  is an inevitability in "real life" information systems, it is therefore imperative that research be conducted on handling imperfection in concept-based query languages.  ...

2006 Lecture Notes in Computer Science  
We introduce a novel view on how to deal with the problems of semantic interoperability in distributed systems.  ...  This view is based on the concept of emergent semantics, which sees both the representation of semantics and the discovery of the proper interpretation of symbols as the result of a self-organizing process  ...  Acknowledgment We would like to thank Avigdor Gal for his insightful comments and suggestions about this work.  ...

Accommodating imprecision in database systems

Amihai Motro
1990 SIGMOD record  
In reality, however, these assumptions are often invalid, and in recent years considerable attention has been given to issues of imprecision in database systems.  ...  Most database systems are designed under assumptions of precision of both the data stored in their databases, and the requests to retrieve data.  ...  VAGUE extends the relational model with the concept of data metrics, and its query language with a similar-to comparator.  ...

Situation Theory and Channel theory as a Unified Framework for Imperfect Information Management [article]

Farhad Naderian

Learning Visual Semantic Relationships For Proficient Visual Recovery

In this paper, I investigate how to establish the relationship between semantic concepts based on the large-scale real-world click data from image commercial engine, which is a challenging topic because  ...  We further employ a sophisticated hashing approach to transform augmented image tags into binary codes, which are subsequently used for content-based image retrieval task.  ...  The concept relationship with the same or similar meanings in a natural language sense tend to be close in units of Google distance, while concepts with dissimilar meanings tend to be farther apart.  ...
