Filling the gap between natural language expressions and ontology concepts or properties is the new trend in Semantic Web. Ontology lexicalization introduces a new layer of lexical information for ontology properties and concepts. We propose a method based on unsupervised learning for the extraction of the potential lexical expressions of DBpedia propertiesfrom Wikipedia text corpus. It is a resource-driven...
The Web is a huge virtual space where to express and share individual opinions, influencing any aspect of life, with implications for marketing and communication alike. Social Media are influencing consumersâ preferences by shaping their attitudes and behaviors. Monitoring the Social Media activities is a good way to measure customersâ loyalty, keeping a track on their sentiment...
Advancements in robotics have led to an evergrowing repertoire of software capabilities (e.g., recognition, mapping, and object manipulation). However, robotic capabilities grow, the complexity of operating and interacting with such robots increases (such as through speech, gesture, scripting, or programming). Language-based communication can offer users the ability to work with physically and computationally...
We present a natural-language question-answering system that gives access to the accumulated knowledge of one of the largest community projects on the Web â" Wikipedia â" via an automatically acquired structured knowledge base. Key to building such a system is to establish mappings from natural language expressions to semantic representations. We propose to acquire these mappings by data-driven...
This paper presents the Interactive Arabic Dictionary (IAD) developed at the Higher Institute for Applied Sciences and Technology (HIAST). IAD is an interactive web application based on the “Al-Wasseet” dictionary. It provides the different meanings of words with examples and multimedia illustrations. IAD presents also other related information like associated words, semantic domains, expressions,...
Conversion from Bangla language to another native language using Universal Networking Language (UNL) is highly demanding due to increasing the usage of Internet based application. Since Bangla case structure plays a fundamental role in Bangla grammartical structures, this paper presents some rules for Bangla case structures that will be used to convert Bangla sentence to UNL expression. The theoretical...
With the blast of information available on the web and the relevant documents set returned by search engineer can not meet the user's needs, the question answer system research is promoted. In this paper, we introduce the structure of Question Answer system based on SOA, define the structure of the dictionary of Keywords and searching template, the word segmentation algorithm based on the dictionary...
Parsing unstructured local web queries is often tackled using simple syntactic rules that tend to be limited and brittle. Here we present a data-driven approach to learning a query parser for local-search (geographical) queries. The learnt model uses class-level ngram language model-based features; these ngram language models, harvested from structured queries logs, insulate the model from surface-level...
Documents' summarization techniques automatically extract relevant information from different sources with respect to a list of topics: they can be profitably used by a variety of applications and in particular for automatic indexing and categorization in order to facilitate the production and delivery of new multimedia contents. In this paper we propose a novel approach for summarizing documents...
This paper explores the possibility of applying a model of natural language communication to textual databases and the WWW. The model, called Database Semantics (DBS), is designed as an artificial cognitive agent with a hearer mode, a think mode, and a speaker mode. For the application at hand, the hearer mode is used for (i) parsing language data into sets of proplets, defined as non-recursive feature...
Deep Web information integration has become more and more important due to its rich and high quality data. How to select the most appropriate web database relevant to user's requirement is challenging. However, the existing researches only focus on the data source selection method and ignore the expression of user's query requirement. This paper presents a user query requirements modeling language,...
The world has fundamentally changed as the Internet has become a universal means of communication. The Web is a huge virtual space where to express individual opinions and influence any aspect of life. Internet contains a wealth of data that can be mined to detect valuable opinions, with implications even in the political arena. Nowadays the Web sources are more accessible and valuable than ever before,...
Advances in communication technologies have made it easier to distribute and communicate information effectively. The world has become a global village with the advent of the Internet. Besides getting the benefits of information technology, the world faces threats of violations of copyright, digital counterfeiting, privacy and plagiarism. These issues have been addressed for image, audio and video...
The key question with Service Science is to be how to formulate a theoretic foundation for service description, service discovery and service composition in the context of basic service system development and the building of service architecture. However, the current research and development in the field of Service Science assumes that the mapping between the service requesters' requirements and the...
On the one hand, natural language is the main communication media for humans. It has a complex construction, based on the diversity of meaning for words and expressions according to the context. On the other hand, computers are not prepared to handle this ambiguity. The present work aims at presenting a multi-agent approach for dealing with the problem of discovering the meaning of expressions written...
