Attempting to use Tsql2 in a natural language interface for temporal databases has focused our attention on certain points in the semantics of Tsql2 where we believe that clariications or modiications are needed. It has also led us to some extensions to Tsql2 that seem generally useful, regardless of natural language issues.

We define semantic comple=ity using a new concept of mesni~g automata. We measure the semantic complexity of understanding of prepositional phrases, of aa "in depth understanding system", and ofa :natural language interface to an on-line calendar. We argue that it is possible to measure some semantic complexities of-natural langu~e processin8 systems before building them, and that.systems:that ...

The Problem: With recent advances in computer and Internet technology, people have access to more information than ever before. As the amount of information grows, so does the problem of finding what one is looking for. We believe that the most natural form of communication and information access for humans is natural language. We propose to address the growing information access problem with a...

In this paper, we describe an improvement on the task of giving instructions to robots in a simulated block world using unrestricted natural language commands.

This project aims to build an ontology authoring interface in which the user is engaged in a dialogue with the system in controlled natural language. To investigate what such a dialogue might be like, a layered annotation scheme is being developed for interactions between ontology authors and the Protégé ontology authoring environment. A pilot experiment has been conducted with ontology authors...

We present the results of the VarDial Evaluation Campaign on Natural Language Processing (NLP) for Similar Languages, Varieties and Dialects, which we organized as part of the fourth edition of the VarDial workshop at EACL’2017. This year, we included four shared tasks: Discriminating between Similar Languages (DSL), Arabic Dialect Identification (ADI), German Dialect Identification (GDI), and ...

Performance of Natural Language Interface often deteriorates due to linguistic phenomena of Semantic Symmetry and Ambiguous Modification (Katz and Lin, 2003). In this paper we present algorithms to handle problems caused by semantic symmetry and ambiguous modification. Use of these algorithms has improved the precision of Natural Language Interface. Proposed shallow parsing based algorithms red...

We describe the construction of a generic natural language query interface to an XML database. Our interface can accept an arbitrary English sentence as a query, which can be quite complex and include aggregation, nesting, and value joins, among other things. This query is translated, potentially after reformulation, into an XQuery expression. The translation is based on mapping grammatical pro...
