The 26th International ACM SIGACCESS Conference on Computers and Accessibility

Welcome to ACM ICTIR 2021, the 7th conference with that name to be fully sponsored by the ACM Special Interest Group on Information Retrieval (SIGIR), and the 11th International Conference on the Theory of Information Retrieval. ICTIR is the premier forum for presenting and discussing research on theoretical and foundational aspects of Information Retrieval. ICTIR 2021 is held online due to the COVID-19 pandemic, jointly with the 44th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR 2021). We would like to express our sincere gratitude to the SIGIR organizing committee for providing organizational and administrative support for hosting the virtual event. The call for papers attracted high quality contributions from all over the world. We received 69 paper submissions and accepted 35 (or 51%) of them. We note that the acceptance rate is not a quality indicator, as our submission pool consisted of high quality papers. For each paper, we assigned 3 PC members to provide first-level reviews, resulting in a total of 207 reviews. The final acceptance decisions were made by the PC co-chairs based on the reviews and comments during the discussion period. We express special thanks to the 52 Program Committee (PC) members and a number of additional reviewers for their timely contributions to paper selection. We also thank the committee of the best paper awards chaired by Krisztian Balog. As a new trial for this year, we allow authors to submit papers of any number of pages between 2 and 9 in content plus unrestricted space for references. Thus, there is no longer a distinction between long and short papers, nor a need for condensing or enlarging medium-length ones. In the reviewing process, the reviewers assessed whether the contribution is appropriate for the given length. We sincerely hope this new streamlined process will preserve the variety of paper lengths and foster the exchange of ideas without creating an artificial distinction among them.

Welcome to the 11th International ACM Sigsoft Conference on the Quality of Software Architectures -- QoSA 2015. For more than a decade, QoSA has strived to advance the state of the art of quality aspects of software architecture, focusing broadly on its quality characteristics and how these relate to the design of software architectures. Specific issues of interest are defining and modeling quality measures, evaluating and managing architecture quality, linking architecture to requirements and implementation, and preserving architecture quality throughout the system lifetime. Past themes for QoSA include Architecting for Adaptivity (2014), The System View (2013), Evolving Architectures (2012), Quality throughout the Software Lifecycle (2011), and Research into Practice -- Reality and Gaps (2010). QoSA 2015's theme is "Software Architecture for the 4th Industrial Revolution". After mechanization, mass production, and electronics, the Internet is about to enable a new level of productivity in manufacturing. This shall be enabled by smart cyber-physical systems connected to cloud computing services and communicating using standardized semantics. In the near future, industrial big data analytics on monitored sensor data shall improve the efficiency and individualization of production facilities. This year's QoSA conference solicited contributions that explore the various implications of this upcoming industrial revolution on software architecture. This included reference architectures, software architectures adapting at run time, architecture styles and patterns for cyber-physical and distributed systems. The call for papers attracted 42 initial submissions from Asia, North America, Africa, and Europe and 28 final submissions were considered during the review process. The program committee accepted 11 full papers and 2 short papers that cover topics, such as new architecture modeling approaches, architectural tactics for mobile computing, cloud computing architectures, and cyberphysical systems. QoSA's 2015 proceedings also include 2 papers from the WCOP 2015, the 20th International Doctoral Symposium on Components and Architecture. QoSA 2015 is part of the federated events on component-based software engineering and software architecture (CompArch 2015), which include WICSA 2015 (12th Working IEEE / IFIP Conference on Software Architecture) and CBSE 2015 (18th International ACM SIGSOFT Symposium on Component-Based Software Engineering).

The 26th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2024) was held October 27th to 30th, 2024 as a hybrid event in St. John's, Newfoundland and Labrador, Canada. The ASSETS conference is the premier computing research conference exploring the design, evaluation, and use of computing and information technologies with and for people with disabilities and older adults. This year, the ASSETS conference continued its tradition of presenting innovative research on mainstream and specialized assistive technologies, accessible computing, and assistive applications of computer, network, and information technologies. 341 attendees from 24 countries attended the conference, including 233 in-person, 50 workshop-only, and 58 virtual attendees.

Recommender systems have become indispensable tools for enhancing user satisfaction and engagement across diverse business sectors, including online marketplaces, streaming services, and e-commerce platforms. This research proposes and evaluates an advanced product review recommendations system that leverages collaborative filtering techniques to deliver personalized and accurate suggestions. By integrating memory-based and model-based collaborative filtering approaches, the system effectively analyses user-item interactions to predict preferences. A key innovation of this study is the application of Singular Value Decomposition (SVD) to decompose the user-item matrix, which not only improves prediction efficiency but also reduces computational demands by addressing data sparsity and dimensionality challenges. The system employs item-based collaborative filtering, utilizing the KNNWithMeans algorithm, and achieves a prediction accuracy of 1.34 RMSE, as validated through rigorous testing on a large-scale electronics product review dataset. Additionally, a correlation-based method is implemented to identify strongly associated products, enabling the generation of highly relevant recommendations. Experimental results demonstrate that the proposed framework outperforms existing recommendation models in terms of scalability and accuracy, particularly for large datasets. Furthermore, this research explores the potential of hybrid models and deep learning techniques to further enhance recommendation quality and mitigate common issues such as the cold-start problem and data sparsity. The findings highlight the system’s robustness in real-world applications and its adaptability to dynamic user behaviour. By combining collaborative filtering with matrix factorization, this study provides a scalable and efficient solution for modern e-commerce platforms seeking to improve user experience and drive sales. Future directions include integrating real-time processing capabilities and exploring advanced machine learning algorithms to refine recommendation precision. References Afshar, M. Z. (2023).

It is our great pleasure to welcome you to the 8th International ACM Sigsoft Conference on the Quality of Software Architectures -- QoSA'12. For almost a decade, QoSA aims at advancing the state of the art in the quality assessment and management for software architectures. Specific issues of interest are defining quality measures, evaluating and managing architecture quality, linking architecture to requirements and implementation, and preserving architecture quality throughout the lifetime of the system. Past themes for QoSA include Quality throughout the Software Lifecycle (2011), Research into Practice -- Reality and Gaps (2010), Architectures for Adaptive Software Systems (2009), and Models and Architecture (2008). The umbrella theme of QoSA 2012 is Evolving Architectures. The QoSA'12 call for papers attracted 52 abstracts leading to the final number of 44 submissions from Europe, North and South America, Australia, Asia, and Africa. The program committee accepted 11 long papers and 7 short papers that cover a variety of topics related to the quality of software architectures. In addition, the program includes two keynote speeches, first by Alberto Montresor (University of Trento, Italy) on Designing Extreme Distributed Systems: Challenges and Opportunities, and second by Johan Bendz (Convenor of the ISO/IEC-JTC1-SC7 Working Group on Architecture) on International Standards Supporting Quality in Software Architecture. QoSA is part of the federated event CompArch, this year together with "CBSE 2012: 15th International ACM SIGSOFT Symposium on Component Based Software Engineering," "ISARCS 2012: 3rd International ACM SIGSOFT Symposium on Architecting Critical Systems," "WCOP 2012: 17th International Doctoral Symposium on Components and Architecture," and "ROSS 2012: Workshop on Reusing Open-Source Components." We are grateful to the organizers of all these events for making CompArch a successful federated event on Component-based Software Engineering and Software Architecture.

It is our great pleasureIt is our great pleasure to welcome you to the 8th International ACM SIGACCESS Conference on Computers & Accessibility - ASSETS 2006. This year's conference continues its tradition of being the premier forum for presentation of research results and experience reports on leading edge issues of the design, development, and application of computer-based methodologies to achieve the objectives of universal access, with special attention to the needs of people of all ages and with different capabilities. Computer and Information Technologies have re-designed the way modern society operates. In particular, they have identified new avenues to assist individuals with special needs and provide tools and resources to alleviate the traditional barriers encountered by people with disabilities. For example, speech generation systems have assisted people with visual impairments and blindness, voice recognition has helped people with motor impairments, and multi-modal presentations have been shown to be effective in helping people with learning disabilities. The ASSETS series of conferences is aimed at providing a technical forum for presenting and disseminating innovative research results that cover either (1) applications of computing and information technologies to provide assistive systems to people with special needs, or (2) investigation of computing technologies and their use by people with disabilities. As in previous years, the conference is organized in such a way as to promote an open forum where researchers, practitioners, educators, and students can present their ideas as formal papers, posters, demonstrations, as well as engage in dialogue, sharing experiences, objectives, accomplishments and different perspectives. In this tradition, ASSETS 2006 is developed as a single-track conference, where formal presentations, interactive sessions, panels, and social events alternate throughout the conference programme.This year, the conference opened with a plenary address by Dr. Sara J. Czaja, Professor in the Departments of Psychiatry and Behavioral Sciences, and Industrial Engineering at the University of Miami. Her presentation was "Technology and Older Adults: Designing for Accessibility and Usability". The technical programme was composed of 28 formal papers, selected by the international programme committee out of a total of 78 submissions. The accepted submissions represent the work of 94 authors from Canada, Czech Republic, France, Germany, Japan, UK, and the USA. The papers were organized in 7 thematic sessions. The programme also includes 2 sessions dedicated to the presentation of cutting-edge results and work-in-progress, in the form of demonstrations and posters, chaired by John Black. Posters and demos were submitted in response to a separate call for papers, which generated 45 submissions, of which 34 were selected for presentation. A 2-page abstract for each poster and demonstration appears in these proceedings. Both technical papers and poster/demonstration papers were subjected to a competitive peer-review process, ensuring that the papers included in these proceedings represent the state-of-the-art in the field. The programme was completed by the student research competition and the doctoral consortium. The doctoral consortium, chaired by Yeliz Yesilada and Andrew Sears, offers an opportunity to doctoral students to present their ideas to both peers and a selected pool of experts. New for this year is the SIGACCESS student research competition (sponsored by Microsoft Research) and chaired by Clayton Lewis. The SRC differs from the doctorial consortium in that entrants can be undergraduate or graduate students. A small number of semi finalists were chosen by the judges to present their work in the conference and of those three students were designated as finalists by the judges, and entered in to the Grand Finals of ACM's Student Research Competition.Following the tradition of the previous ASSETS, SIGACCESS will present two awards: the SIGACCESS Best Technical Paper Award and the SIGACCESS Best Student Paper Award. The success of a conference depends on the contributions of many people. Some are named in the following organizing roster, but many more have contributed to the development of this event. We wish to thank all of them for their truly exceptional job.

2016 12th International ACM SIGSOFT Conference on Quality of Software Architectures (QoSA)

Welcome to ACM ICTIR 2022, the 8th conference with that name to be fully sponsored by the ACM Special Interest Group on Information Retrieval (SIGIR), and the 12th International Conference on the Theory of Information Retrieval. ICTIR is the premier forum for presenting and discussing research on theoretical and foundational aspects of Information Retrieval. ICTIR 2022 is a hybrid event combining "live" (in-person) presentations with a "virtual" online component due to the COVID-19 pandemic. ICTIR 2022 is jointly held in Madrid (Spain) with the 45th International ACM SIGIR Conference on Research and Development in Information Retrieval (SIGIR 2022). The call for papers attracted 80 high quality contributions from all over the world. The reviewing was carried out in just over one month and resulted in the acceptance of 32 papers (a 40% acceptance rate). For each paper, we assigned 3 Program Committee (PC) members to provide first-level reviews. The final acceptance decisions were made by the PC co-chairs based on the reviews and on the comments submitted during the discussion period. Unfortunately, a few reviews (6) were not submitted in time, so for the final decision particular care was given to the comments submitted by reviewers. We express special thanks to the 60 PC members for their timely assessments and help in the paper selection. We also thank the small committee for the best paper awards chaired by Hideo Joho. Following the example of last year, we allowed authors to submit papers of any number of pages between 2 and 9 in content plus unrestricted space for references. This created no distinction between long and short papers at submission time. In the reviewing process, the reviewers assessed whether the contribution was appropriate for the given length. Then, based on the content of the papers, a decision was taken by the PC Chairs with regards to their presentation time. This new streamlined process, a continuation of last year experiment, is meant to preserve the variety of paper lengths and foster the exchange of ideas without creating an artificial distinction among papers. Time will tell if this is a good idea.

This volume contains the papers presented at PPDP 2010, the 12th International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming, held in Hagenberg, Austria, 26--28 July 2010. The PPDP series of conferences is a major forum for researchers and practitioners in the declarative programming communities to present results on leading edge issues of logic, constraint and functional programming, as well as related paradigms. The goal is to stimulate research in the use of logical formalisms and methods for specifying, performing, and analysing computations, including mechanisms for mobility, modularity, concurrency, object-orientation and security. PPDP 2010 continued this tradition, bringing together researchers from the declarative programming communities and related areas (such as specification and theorem proving, database languages, AI languages and knowledge representation) and researchers applying declarative programming techniques to a variety of domains (for example, web services, concurrency, business rules, program analysis, language implementation, etc). This year, 57 papers were submitted to PPDP, and out of 46 papers reviewed the programme committee selected 21 papers for presentation in the symposium. The program committee used the EasyChair conference management system for handling electronic submissions, allocating reviewing duties, and managing reviews. In addition to regular paper sessions, the symposium included two invited talks by Maria Paola Bonacina (Universitàdegli Studi di Verona, Italy) and Sumit Gulwani (Microsoft Research, USA). PPDP 2010 was part of the RISC Summer 2010, a series of international scientific events organised by the Research Institute for Symbolic Computation (RISC) of the Johannes Kepler University Linz. It was colocated with the 20th International Symposium on Logic-Based Program Synthesis and Transformation (LOPSTR 2010). The symposium was organised in cooperation with ACM SIGPLAN and was sponsored by the Johannes Kepler University Linz, provincial government of Upper Austria, Austrian Federal Ministry of Science and Research, Linzer Hochschulfonds, Doctoral Program "Computational Mathematics" (W1214), and Linz AG. Lisa Tolles at Sheridan Printing managed the production of these proceedings.

This issue's column reports on papers from the 19th International Conference on Model Driven Engineering Languages and Systems, the 2016 ACM SIGPLAN International Conference on Software Language Engineering, the 12th International ACM SIGSOFT Conference on the Quality of Software Architectures, and the 13th Working IEEE/IFIP Conference on Software Architecture. Topics discussed include GitHub and open source, technical debt in model-driven engineering, a universal code formatter, assuring architectural quality, and continuous architecting.

This volume contains the papers presented at PPDP 2008, the 10th International ACM SIGPLAN Symposium on Principles and Practice of Declarative Programming, held July 15-17, 2008, in Valencia, Spain. The Symposium is a forum for researchers in the declarative programming communities, including those working in the logic, constraint, and functional programming paradigms, but also embracing a variety of other paradigms such as visual programming, executable specification languages, database languages, AI languages, and knowledge representation languages used, for example, in the semantic web. The goal is to stimulate research in the use of logical formalisms and methods for specifying, performing, and analyzing computations, and to stimulate cross-fertilization by including work from one community that could be of particular interest and relevance to the others This year's PPDP was co-located with the 15th International Static Analysis Symposium (SAS 2008), the 18th International Symposium on Logic-Based Program Synthesis and Transformation (LOPSTR 2008), and the 4th International Workshop on Programming Language Interference and Dependence (PLID 2008). Out of 51 initial submissions, 48 papers were reviewed by four referees and 24 were selected for presentation. The program committee used the EasyChair conference management system for handling electronic submissions, for allocating reviewing duties, and for filing reviews. In addition to regular paper sessions, the symposium hosted an invited talk by Michael Leuschel of the University of Düsseldorf, Germany.
