1 Big Data Management Using Ontologies for CPQ Solutions
مدیریت داده های بزرگ با استفاده از هستی شناسی برای راه حل های CPQ-2020
In recent years, due to a progressive complexity of handling and processing business data, proper big data management has become a challenge, especially for SMEs that have limited resources for investing in the requested business transformation process. As a solution, we suggest an ontology-based CPQ software approach, where we show how the implementation of semantic technologies and ontologies affects data integration processes. We also propose a method called “ontology-based data matching”, which allows the semiautomatic generation of alignments used to formalize the coherence between ontologies. The proposed method will ensure consistency during integration, significantly improving the productivity of enterprises.© 2020 The Authors. Published by Elsevier B.V.

2 The Training Data Evaluation Tool: Towards a unified ontology-based solution for industrial training evaluation
ابزار ارزیابی داده های آموزشی: به سوی راه حل مبتنی بر هستی شناسی یکپارچه برای ارزیابی آموزش های صنعتی-2018
With the increasing diffusion of the Industry 4.0 paradigm, the role of industrial training is becoming more and more relevant. Thanks to new technologies and innovative business processes now available, a great amount of data can be collected from the shop floor and elaborated in order to provide a real-time evaluation of the expertise level of the workers. In this regard, the paper aims at presenting and expanding the Training Data Evaluation Tool previously developed by the authors. Results achieved pave the way towards the final deployment of the Training Evaluation suite of Ontologies through an integrated software stack using semantic technologies for knowledge management along with a Training Analytics Model. Integration tests of the used technologies have been carried out using real industrial data showing the feasibility and robustness of the proposed solution.

3 An architecture for aggregating information from distributed data nodes for industrial internet of things
یک معماری برای جمع آوری اطلاعات از گره های داده توزیع شده برای اینترنت اشیاء صنعتی -2017
The current Internet of Things (IoT) has made it very convenient to obtain information about a product from a single data node. However, in many industrial applications, in formation about a single product can be distributed in multiple different data nodes, and aggregating the information from these nodes has become a common task. In this paper, we provide a distributed service-oriented architecture for this task. In this architecture, each manufacturer provides service for their own products, and data nodes keep the infor mation collected by themselves. Semantic technologies are adopted to handle problems of heterogeneity and serve as the foundation to support different applications. Finally, as an example, we illustrate the use of this architecture to solve the problem of product tracing.

4 An associative engines based approach supporting collaborative analytics in the Internet of cultural things
یک رویکرد مبتنی بر موتورهای انجمنی رای پشتیبانی از تجزیه و تحلیل مشارکتی در اینترنت اشیا فرهنگی-2017
In this paper we illustrate an integrated approach combining Business Intelligence, Big Data and Internet of Things (IoT), which is applied to information resources including structured and unstructured contents, Geo-Spatial and Social Network data, Multimedia (MM), multiple domain vocabularies, classifiers and ontologies. This is implemented in an information system which exploits Associative in-memory technologies in the context of Cloud Computing, as well as Semantic technologies for merging and analyzing information coming from heterogeneous sources. The primary aim is supporting Cultural Heritage Asset crowdsourcing, promotion, publication, management and usage. We describe and discuss, in particular, the application of this system for the analysis of behavior and interest of visitors in different types of populations and visits: on-site/ad-hoc (exhibitions, museums, cultural events) and territorial (historical downtown, archaeological or other touristic areas and routes including cultural resources). In this way it will be possible to provide a common ICT infrastructure and a set of advanced services for all types of subjects interested in the Cultural Heritage domain. The results of the experimentation encourage a Business Intelligence approach which is suitable for both nonprofit, research and business oriented organizations.

5 Semantic Reasoning for Context-Aware Internet of Things Applications
استدلال معنایی برای برنامه های کاربردی متن-آگاه اینترنت اشیاء -2017
Acquiring knowledge from continuous and heterogeneous data streams is a prerequisite for Internet of Things (IoT) applications. Semantic technologies provide comprehensive tools and applicable methods for representing, integrating, and acquiring knowledge. However, resourceconstraints, dynamics, mobility, scalability, and real-time requirements introduce challenges for applying these methods in IoT environments. We study how to utilize semantic IoT data for reasoning of actionable knowledge by applying stateof-the-art semantic technologies. For performing these studies, we have developed a semantic reasoning system operating in a realistic IoT environment. We evaluate the scalability of different reasoning approaches, including a single reasoner, distributed reasoners, mobile reasoners, and a hybrid of them. We evaluate latencies of reasoning introduced by different semantic data formats. We verify the capabilities of promising semantic technologies for IoT applications through comparing the scalability and real-time response of different reasoning approaches with various semantic data formats. Moreover, we evaluate different data aggregation strategies for integrating distributed IoT data for reasoning processes.

7 A Comprehensive Semantic Model for Smart Object Description and Request Resolution in the Internet of Things
یک مدل معنایی جامع برای توضیح و درخواست اشیا هوشمند در اینترنت اشیاء-2016
The Internet of Things is a natural continuity of the Ambient Intelligence where smart and ambient environments are built by integrating a large number of interconnected smart objects with heterogeneous capabilities abstracted as software services. The aim is to design cross-domain applications that compose and select most relevant services, which best match user requirements and closely meet the specified quality-of-service level. However, semantic description and representation of such smart devices, including their hosted services and their provided real world data, is still a challenging issue. Semantic Web technologies are seen as a promising tool for this purpose. Indeed, applying these technologies in the Internet of Things enables smart objects to efficiently share their data, exchange their services and cooperate to better satisfy both functional and non-functional user requirements. In this paper, we propose a new semantic model for smart objects description and users request resolution using ontological techniques combined with description logics. Such a model facilitates intelligent functions, including reasoning over service data and semantic interoperability enabling among devices. A case study for smart environment monitoring has been proposed to illustrate the effectiveness and usability of our approach.

8 A More Human-centric Internet of Things with Temporal and Spatial Context
اینترنت اشیاء انسان محور با زمینه های زمانی و فضایی-2016
As the Internet of Things evolves, attention has been paid to adding intelligence capabilities, some of them via semantic tech nologies. However, many of these developments are still too device-centric and more needs to be done to make the IoT more people-centric. One important aspect in this direction is supporting spatial constructs that are meaningful to humans. We present the OpenThings platform as a basis to provide meaning via semantic technologies and demonstrate how it can be used to build environments that take into account a human-centered view of temporal and spatial context. We exemplify this by building a prototype for a system that supports proxemic interactions and time awareness.
