Integrating natural language components into graphical discourse

Stephan Dilley, John Bateman, Ulrich Thiel, Anne Tissen
1992 Proceedings of the third conference on Applied natural language processing -  
We illustrate the need for such a combined system, and also give examples of how a general natural language facility beneficially augments the user's ability to navigate a knowledge base graphically.  ...  This is intended to support the generation of flexible natural language utterances which pinpoint possible problems with a user's request and which further go on to outline the user's most sensible courses  ...  The most interesting aspect in this plan is the use of rhetorical relations based on Rhetorical-Structure-Theory (RST).  ...

A Comprehensive Survey on Query Expansion Techniques, their Issues and Challenges

Neha Kathuria, Kanika Mittal
2017 International Journal of Computer Applications  
In order to improve the retrieval performance, the process of Query expansion is performed on the original user's query in order to reformulate the user's query.  ...  Various query expansion techniques do not consider the context of the terms present in the user's query which can result in low precision and recall due to the ambiguity and vagueness of terms present  ...  CONCEPT NETWORK BASED QUERY EXPANSION In [10] , Orland et al. proposed a method based on conceptual semantic theories in which the queries were expanded from concept network knowledge base.  ...
