It is a long term desire of the computer users to minimize the communication gap between the computer and a human. Natural Language Interfaces to Databases (NLIDBs) is one of the mechanisms to pull off this goal. In NLIDBs the question is asked in simple daily life human language and the answer is given in the same language. This research paper is about(More)
Handling of human language by computer is a very intricate and complex task. In natural languages, sentences are usually part of discourse units just as words are part of sentences. Anaphora resolution plays a significant role in discourse analysis for chopping larger discourse units into smaller ones. This process is done for the purpose of better(More)
A Probabilistic Context Free Grammar (PCFG) for Urdu is developed from an already developed Context Free Grammar (CFG) for sentences and phrases. Probabilities are assigned to the rules and two new terms i.e. special weights and special probability are introduced and assigned to few rules. Weights are assigned to rules after performing calculations based on(More)
This paper provides an overview of the development of a general-purpose reference corpus for Pashto. It is an open-ended (monitor) corpus. The corpus currently contains 10,000 words. It has two cells, one containing essays and the other letters. This corpus represents Yousafzai group of dialects and the data for it has been provided by the Pashto Academy,(More)
The prerequisite to any software development process is to first capture and understand the intended behaviour of the software solution based on the gathered requirements and understanding the constraints related to it. Hence requirement engineering becomes a very crucial step. Requirements are specified in Natural language by the user and it has to be(More)
Organizations and individuals are mainly concerned to get opinions about different products, services and events for making suitable choices. The main contribution of this research is the design of an ontology that will help a user to select appropriate (popular) tools for web designing on the basis of certain characteristics and features of tools. The(More)
This paper is about the development of Pashto Treebank in the form of Extensible Markup Language (XML) code. A Chart Parser has been developed that uses Chart Parsing Algorithm [1] for building parse trees for Pashto sentences. The output of the parser is the parsed text which can be obtained in one of its three forms such as reduced graph, parse tree and(More)
Computational treatment of natural languages is a very challenging task. For effective machine translation of multi-sentential discourse units from a source language into some target language, resolution of anaphoric expressions is of crucial importance. This paper presents the computational treatment of the rarely studied form of pronominal reference(More)
