The appearance of valuable Linked Data sources as part of the LOD in the last few years and the emergence of Semantic Web services has opened new horizons for web and data research. Moreover, machine-understandability of semantics allows for efficient search and integration of data. Based on the existing standards and techniques, we address the problem of searching data and services in the LOD....

Semantic Web services provide semantically enhanced service descriptions which allow the development of automated service discovery and composition. Yet, an efficient semantic-based service discovery remains a major open challenge towards a wide acceptance of semantic Web services. In this paper we present a fully-automated matchmaking system for discovering sets of OWL-S Web services capable o...

This paper aims at studying the speech act of congratulation in Persian and English with regard to semantic formulas. To gather the semantic formulas related to congratulation, the researchers chose 100 movies (50 in Persian and 50 in English) as the instrument of the study. The only model of cross-cultural comparison was related to that of Elwood (2004). Therefore, we used Elwood’s model as th...

Dynamic composition of web services is a promising approach and at the same time a challenging research area for the dissemination of service-oriented applications. It is widely recognised that service semantics is a key element for the dynamic composition of Web services, since it allows the unambiguous descriptions of a service’s capabilities and parameters. This paper introduces a framework ...

Semantic Web service composition is a discovery process in which a given set of requirements are fulfilled by locating and assembling semantically annotated services. Semantic annotation of Web services is based on expanding the description of Web services with formal semantic models, such as OWLS [2]. These models provide an unambiguous description of service properties by relating them to con...

Recent studies in multi-agent systems are paying increasingly more attention to the paradigm of designing intelligent agents with human inspired concepts. One of the main cognitive concepts driving the core of many recent approaches in multi agent systems is shared mental models. In this paper, we propose an architecture for sharing mental models based on a new concept called semantic movement....

This paper presents a new algorithm that arrives at a generalized solution for the generation of restricted weak compositions of n-parts. In particular, this generalized algorithm covers many commonly sought compositions such as bounded compositions, restricted compositions, weak compositions, and restricted part compositions. Introduced is an algorithm for generating generalized types of restr...

Supporting service discovery by semantic service specifications is currently an important research area. While the approaches for the annotation of individual services are well researched, determining the semantics of compositions of services remains an open research issue. In this paper, we present an approach to generate the semantics of service compositions from the semantics of the containe...

As protection of web applications are getting more and more important every day, CAPTCHAs are facing booming attention both by users and designers. Nowadays, it is well accepted that using visual concepts enhance security and usability of CAPTCHAs. There exist few major different ideas for designing image CAPTCHAs. Some methods apply a set of modifications such as rotations to the original imag...

In this paper, we study the problem of "learning new compositions of words from given ones with a specific syntactic structure, e.g., A-N or V-N structures. We first cluster words according to the given compositions, then construct a cluster-based compositional frame for each word cluster, which contains both new and given compositions relevant with the words in the cluster. In contrast to othe...
