The ability to extract insights from new data sets is critical for decision making. Visual interactive tools play an important role in data exploration since they provide non-technical users with an effective way to visually compose queries and comprehend the results. Natural language has recently gained traction as an alternative query interface to databases with the potential to enable non-ex...

In this paper we look at what may be learned from a comparative study examining non-technical users with a background in social science browsing and querying metadata. Four query tasks were carried out with a natural language interface and with an interface that uses a web paradigm with hyperlinks. While it can be difficult to attribute differences in performance to specific design features, a ...

This paper proposes an interface that uses automatically-generated Natural Language (NL) descriptions to describe indoor scenes based on photos taken of that scene from smartphones or other portable camera-equipped mobile devices. The goal is to develop a non-visual interface based on spatio-linguistic descriptions which could assist blind people in knowing the contents of an indoor scene (e.g....

Information is playing an important role in our lives. One of the major sources of information is databases. Databases and database technology are having major impact on the growing use of computers. Almost all IT applications are storing and retrieving information from databases. Retrieving information database requires knowledge of database languages like SQL. The Structured Query Language (S...

In this article, in order to enable a novice user to interact with the temporal database system and simplify the query processing in temporal database system, a Temporal Natural Language Interface(TNLP) has been designed and implemented. Object evolution in temporal databases is interesting, but none of the SQL-like algebraic languages take evolution into account. This work makes use of a tempo...

Accessing structured data such as that encoded in ontologies and knowledge bases can be done using either syntactically complex formal query languages like SPARQL or complicated form interfaces that require expensive customisation to each particular application domain. This paper presents the QuestIO system – a natural language interface for accessing structured information, that is domain inde...

This paper describes a general approach to the design of natural language interfaces that has evolved during the development of DATALOG, an English database query system based on Cascaded ATN grammar. By providing separate representation schemes for linguistic knowledge, general world knowledge, and application domain knowledge, DATALOG achieves a high degree of portability and

The Natural language question (NLQ) processing module is considered a fundamental component in the natural language interface of a Question Answering (QA) system, and its quality impacts the performance of the overall QA system. The most difficult problem in developing a QA system is so hard to find an exact answer to the NLQ. One of the most challenging problems in returning answers is how to ...

We present a Natural Language Interface (nlmaps.cl.uni-heidelberg.de) to query OpenStreetMap. Natural language questions about geographical facts are parsed into database queries that can be executed against the OpenStreetMap (OSM) database. After parsing the question, the system provides a text-based answer as well as an interactive map with all points of interest and their relevant informatio...

Unmanned vehicles, such as mobile robots, must exhibit adjustable autonomy. They must be able to be self-sufficient when the situation warrants; however, as they interact with each other and with humans, they must exhibit an ability to dynamically adjust their independence or dependence as co-operative agents attempting to achieve some goal. This is what we mean by adjustable autonomy. We have ...
