The fast growth of Internet is creating a society where the demand on information storage, organization, access, and analysis services is continuously growing. This constantly increases the number of inexperienced users that need to access databases in a simple way. Together with the emergence of voice interfaces, such a situation foretells a promising future for database querying systems using...

Computer security is a very important issue these days. Computer viruses, worms, Trojan horses, and cracking are prevalent and causing serious damages. There are also many ways developed to defend against such attacks including cryptography and firewalls. However, it is not possible to guarantee complete security of computer systems or networks. Recently much attention has been directed to ways...

Developing knowledge bases for AI systems takes too long and costs too much. Even a "portable" system may be expensive to use because its installation takes a long time or requires the labor of scarce, highly-trained people. BBN has recently created a tool for acquisition which dramatically reduces t h e time and cost of installing a natural language system. During 1988, BBN used its Learner tm...

This demonstration presents the Annotation Librarian, an application programming interface that supports rapid development of natural language processing (NLP) projects built in Apache Unstructured Information Management Architecture (UIMA). The flexibility of UIMA to support all types of unstructured data – images, audio, and text – increases the complexity of some of the most common NLP devel...

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. In order to retrieve information from a database, one needs to formulate a query in such way that the computer will understand and produce the desired output. The Structured Query Language (SQL) no...

There is an increasing presence of structured data due to the adoption of Linked data principles on the web. At the same time, web users have different skills and want to be able to interact with Linked datasets in various manner, such as asking questions in natural language. This paper proposed a first implementation of Query Answering system (QA) applied to the Linked Open Vocabularies (LOV) ...

The development of a natural language dialogue system as an interface to a theater information database is a joint research project of the University of Tartu (Estonia) and the Tallinn University of Technology (Estonia). The underlying database contains information about theater performances in a certain theater or city. The dialogue system can be used to ask information about performances usin...

Issues revolving around transportability and technology transfer have been of growing interest to natural language processing development. This paper describes an experiment performed to test the modularity of the Martin Marietta EQUAL natural language processor, by adapting this database interface system to English-Korean machine translation task. The methodology included altering the applicat...

This paper presents a method of querying databases by means of a natural languagelike interface which offers the advantage of minimal configuration necessary for porting the system. The method allows us to first automatically infer the set of possible queries that can apply to a given database, automatically generate a lexicon and grammar rules for expressing these queries, and then provide use...

Interactive conversation agents or CAs are computer programs or application software designed to simulate conversation with one or more human users in natural language. Providing CAs with knowledge, intelligence and humanoid interface has allowed them to be used in several practical applications. This paper presented the development and its performance of the interactive CAs called Artificial I...
