Identifying semantic expressions (so-called concept strings (CSs)) in multilingual corpora is an important NLP task, as it allows web search engines to define and perform semantic queries over large collection of documents. Existing web... more
We concentrate on the use of ontologies for the categorization of objects, e.g., photos, books, web pages. Lightweight ontologies are ontologies with a tree structure where each node is associated a natural language label. Faceted... more
International journal of Web & Semantic Technology (IJWesT) is a quarterly open access peer- reviewed journal that provides excellent international forum for sharing knowledge and results in theory, methodology and applications of web &... more
Enabling applications that exploit heterogeneous data in the Semantic Web will require us to harness a broad variety of semantics. Considering the role of semantics in a number of research areas in computer science, we organize semantics... more
Traditional Information Retrieval (IR) systems are based on bag-of-words representation. This approach retrieves relevant documents by lexical matching between query and document terms. Due to synonymy and polysemy, lexical methods... more
Both named entities and keywords are important in defining the content of a text in which they occur. In particular, people often use named entities in information search. However, named entities have ontological features, namely, their... more
In the last few years, the use of ontologies has spread thanks to the irruption of the Semantic Web. They have become a crucial tool in information systems as they explicitly state the meaning of information, making it possible to share... more
Digital repositories and digital libraries are today among the most common tools for managing and disseminating digital object collections of cultural, educational, and other kinds of content over the Web. However, it is often the case... more
The searching of relevant content for any particular application area is a challenging task in today’s ocean of knowledge on the web. There are various factors such as user query, search technique and ranking algorithms that af ect the... more
In the economic and financial analysis domain, quick access to the right information plays a major role. Using current systems, the search for and presentation of data is very cumbersome. The data, mostly in form of time-series, is stored... more
Efficient file searching is an essential feature in P2P systems. While many current approaches use brute force techniques to search files by meta information (file names, extensions or user-provided tags), the interest is in implementing... more
The evolution of information retrieval technology on the web has led to the idea of semantic search engine in which it understands the meaning and the context of the search query. As a consequence, the search results returned by this type... more
Rapid Integrated Assessment (RIA) is a United Nations Development Programme procedure involving a comparison between a country’s development policy documents and the UN-defined Sustainable Development Goals. In this paper, we present the... more
