Inform plays a very important role in life and nowadays, the world largely depends on the World Wide Web to obtain any information. Web comprises of a lot of websites of every discipline, whereas websites consists of web pages which are interlinked with each other with the help of hyperlinks. The success of a website largely depends on the design aspects of the web pages. Researchers have done a lot of work to appraise the web pages quantitatively. Keeping in mind the importance of the design aspects of a web page, this paper aims at the design of an automated evaluation tool which evaluate the aspects for any web page. The tool takes the HTML code of the web page as input, and then it extracts and checks the HTML tags for the uniformity. The tool comprises of normalized modules which quantify the measures of design aspects. For realization, the tool has been applied on four web pages of distinct sites and design aspects have been reported for comparison. The tool will have various advantages for web developers who can predict the design quality of web pages and enhance it before and after implementation of website without user interaction.

[Abstract] Context: Web engineering involves managing a high diversity of artifacts implemented in different languages and with different levels of granularity. Technological companies usually implement variable artifacts of Software Product Lines (SPLs) using annotations, being reluctant to adopt hybrid, often complex, approaches combining composition and annotations despite their benefits. Objective: This paper proposes a combined approach to support fine and coarse-grained variability for web artifacts. The proposal allows web developers to continue using annotations to handle fine-grained variability for those artifacts whose variability is very difficult to implement with a composition-based approach, but obtaining the advantages of the composition-based approach for the coarse-grained variable artifacts. Methods: A combined approach based on feature modeling that integrates annotations into a generic composition-based approach. We propose the definition of compositional and annotative variation points with custom-defined semantics, which is resolved by a scaffolding-based derivation engine. The approach is evaluated on a real-world web-based SPL by applying a set of variability metrics, as well as discussing its quality criteria in comparison with annotations, compositional, and combined existing approaches. Results: Our approach effectively handles both fine and coarse-grained variability. The mapping between the feature model and the web artifacts promotes the traceability of the features and the uniformity of the variation points regardless of the granularity of the web artifacts. Conclusions: Using well-known techniques of SPLs from an architectural point of view, such as feature modeling, can improve the design and maintenance of variable web artifacts without the need of introducing complex approaches for implementing the underlying variability.

Wilga 2021 Summer Symposium on Photonics Applications and Web Engineering was the 48th edition of the research and technical meetings series [1,2]. Traditionally, the whole week lasting annual series of technical conferences and topical sessions was scheduled to be held on 26 May – 02 June 2020 in Wilga resort near Warsaw, owned by the Warsaw University of Technology. Nearly 150 participants took part in all of the Wilga 2021 events, most of them being young researchers active in all aspects of photonics, electronics and ICT science and technology. Wilga Symposium also embraces hardware and software technologies associated with photonics like optics, optical engineering, optoelectronics, electronics and electrical engineering, mechatronics, chemical and material engineering, applied physics, industrial solutions and applications. Around 100 papers were presented during Wilga 2021, oral and poster. Out of this number, some papers chosen by authors are published in this volume of Proc. SPIE mostly related to photonics. The major change was that during Wilga 2020 and 2021 Symposia, during summer editions, no traditional large young researcher sessions at large were possible to be organized.

Web Page Classification is decisive for information retrieval and management task and plays an imperative role for natural language processing (NLP) problems in web engineering. Traditional machine learning algorithms excerpt covet features from web pages whereas deep leaning algorithms crave features as the network goes deeper. Pre-trained models such as BERT attains remarkable achievement for text classification and continue to show state-ofthe-art results. Knowledge Graphs can provide rich structured factual information for better language modelling and representation. In this study, we proposed an ensemble Knowledge Based Deep Inception (KBDI) approachfor web page classification by learning bidirectional contextual representation using pre-trained BERT incorporating Knowledge Graph embeddings and fine-tune the target task by applying Deep Inception network utilizing parallel multi-scale semantics. Proposed ensemble evaluates the efficacy of fusing domain specific knowledge embeddings with the pre-trained BERT model. Experimental interpretation exhibit that the proposed BERT fused KBDI model outperforms benchmark baselines and achieve better performance in contrast to other conventional approaches evaluated on web page classification datasets.

Companies currently encounter obstacles in networking, integration, and global manufacturing as mobile devices as well as computers increasingly facilitate commercial activities. Accordingly, we propose a new web-based enterprise resource planning (e-ERP) system that can be rapidly migrated from conventional on-site ERP systems. In this paper, by referring to Internet technologies and several key web topics, we explore the evolution of e-Commerce and ERP. We also discuss the applications of the proposed method based on an elastic model–view–controller e-ERP and software-as-a-service delivery. On the basis of information system architecture evaluation and realization results, we discuss the application of web technologies and web engineering models for the effective hosting of a reliable cloud ERP. In addition, on the basis of a review of the literature and related emerging technologies, we comparatively discuss several holistic frameworks of web application development from the technical and business perspectives. As indicated by the implementation results, the proposed approach can be used to effectively host a secure cloud ERP.

Multimedia platforms dealing with movie streaming and video-based short messages have increased the global Internet video traffic substantially in the last couple of years. Over the same period, multimedia on the Web has been standardized in terms of codecs and browserbased JavaScript APIs. However, today the technological challenges concerning the distribution of large video files are mainly tackled by scaling up capacities in cloud data centers, or relying on content delivery networks. Both approaches favor financially strong, large companies, while independent video providers with highly demanded videos are disadvantaged. Peer-to-peer streaming provides an alternative by shifting the data streams to the clients. In this article, we conceptualize different methods to move video delivery from centralized cloud infrastructures to end user devices.We discuss their strengths & weaknesses and present design considerations. To exemplify a particular approach, we showcase the implementation and evaluation of OakStreaming, our system that streams videos peer-to-peer via WebTorrent in HTML5. Particularly, we offer Web video providers a library that has various parameters, for instance to limit the bandwidth available for peer-topeer uploads. The resulting library is available as open source software on GitHub.

In recent years, agile methodologies have been consolidated and extended in organizations that develop software in Web environments. For this reason, the development methodology of these organizations will not only be related to Services, but also to the Web Engineering paradigm. These organizations are heading for incorporating software development methodologies whose paradigm can allow integration, naturally and in the earlier stages of Web applications develop with the services of the organization that described and published in the Services Portfolio. The aim of this study will be to analyze the current state of the art in the process of discovering services in early stages of agile software development with focus on those identified requirements that could be covered with the services included in the Service Portfolio. We have identified 20 relevant papers through conducting a double systematic literature review (SLR). It is concluded that no study has been found that can solve the entire process of discovering candidate services within an organization that cover the requirements of a new application developed with agile methodologies. At the same time, guidelines have been found to formalize the solution to this problem and fill in that gap of knowledge by proposing in a single process, the formalization of a requirement based on agile techniques, which can be managed against a Services Portfolio.

Data-intensive Web applications are usually developed by means of specific Web application frameworks, which provide, among other features, the proper tools to automate redundant tasks, e.g. the implementation of CRUD operations. However, although Model-Driven Web Engineering (MDWE) approaches have defined specific languages and tools to significantly reduce development efforts, the provision of such automation tools has been traditionally neglected. This paper presents AutoCRUD, a WebRatio plug-in automating the generation of CRUD operations in OMG Interacting Flow Modelling Language (IFML). It has been developed as a joint effort by academia and industry to assess its validity in a real scenario.

Most websites use interactive online forms as the main contact point between users and website owners (e.g. companies, governmental institutions, ect.). Therefore, a proper design of such forms is crucial to allow smooth information exchange. It can be decisive on the success or failure of an online transaction. Users mostly visit a website with an intention that is related to the content of that site (e.g. purchasing an article, gathering information). Hence, they do not visit a website with the intention or goal of filling in a web form. Let us illustrate this with an online shopping example: Once users have chosen the items that they wish to buy, they want to finish their shopping as quickly, easily and safely as possible. But to successfully complete the shopping process users have to provide some personal data such as shipping address or credit card information. In the users perception, an online form may be perceived as a hurdle. There is evidence that unusable web forms lead to customers aborting the transaction prematurely, resulting in loss of profit (Wroblewski, 2008). To prevent such dropouts from the buying process, a revision of the form is necessary. A successful redesign of a suboptimal online form may result in an increased completion rate in the range of 10%-40% (Wroblewski, 2008). For instance, the eBay User Experience and Design Group reported that a redesign of the eBay registration form made a significant contribution to eBay’s business and user success (Herman, 2004). The World Wide Web contains a wide range of different web form design solutions for similar interface aspects and problems. Exemplarily, Figure 1 shows four different ways of implementing and communicating format restrictions to users. It can be seen, that even website developers of major companies choose very different ways to solve the same problems. This raises several important questions: Are these solutions equivalent or are there ways that lead to superior web forms in terms of an enhanced usability? Would it not be advantageous to use similar solutions for similar problems, so that predictability for users can be increased? Are there different solutions that may be used depending on the developer’s intentions? In the last years a growing body of research and guidelines have been published on how to make online forms more usable. They answer to a certain extent the questions mentioned
