This paper aims to propose a conceptual model for improving the organization of user needs information in the big data environment.

A conceptual model of the organization of user needs information based on Linked Data techniques is constructed. This model has three layers: the Data Layer, the Semantic Layer and the Application Layer.

Requirements for organizing user needs information in the big data environment are identified as follows: improving the intelligence level, establishing standards and guidelines for the description of user needs information, enabling the interconnection of user needs information and considering individual privacy in the organization and analysis of user needs.

This Web of Needs model could be used to improve knowledge services by matching user needs information with increasing semantic knowledge resources more effectively and efficiently in the big data environment.

This study proposes a conceptual model, the Web of Needs model, to organize and interconnect user needs. Compared with existing methods, the Web of Needs model satisfies the requirements for the organization of user needs information in the big data environment with regard to four aspects: providing the basis and conditions for intelligent processing of user needs information, using RDF as a description norm, enabling the interconnection of user needs information and setting various protocols to protect user privacy.

The purpose of this paper is to describe UWIRS (Ubiquitous Web Information Retrieval Solution), an agent‐based Web Information Retrieval (WIR) solution designed taking into account the unique features of the World Wide Web (WWW) and the limitations of existing WIR solutions for ubiquitous environments.

UWIRS can offer recommendation services by using the Multi‐Agent Vizier Recommendation Framework (Vizier). Vizier was designed under a generic approach and therefore can provide services to information retrieval applications so these may offer product recommendations that consider several adaptation/personalization dimensions (e.g. user dimension, context, among others).

Overall, the main challenge resides on: location, retrieval, integration and presentation of information from the WWW, quickly and accurately, to satisfy a user's singular information needs.

In UWIRS, agents cooperate in order to retrieve personalized information, considering user needs, goals, preferences and contextual features. UWIRS's agents are responsible for: interpreting user input and adding adaptation information by means of a query enrichment process; identifying and selecting the appropriate data sources taking into consideration the Profile Set (composed of User, Device and Information‐Provider Profiles); executing query routing and the information retrieval process; integrating and filtering the retrieved results; and lastly, coherent presentation of quality and relevant ubiquitous information (anytime, anywhere and anyhow) that satisfies the user's particular information needs and constraints associated to his/her access device.

For the internet to realise its full marketing potential, travel agencies need a well‐designed e‐travel site. Yet the attributes that affect customers' perceptions leading to acceptance of e‐travel sites are still unclear. This study seeks to focus on why users accept or reject e‐travel sites and how users' acceptance is affected by three widely recognised features of sites – relevant information content, information quality, and functionality needs service.

The study analysed a survey of 242 users of Taiwanese e‐travel sites to test the hypothesised expanded technology acceptance model.

The empirical results indicate that the information content, information quality and functionality service of e‐travel sites strongly determine the perceived ease of use. Relevant information content and information quality also strongly determine perceived usefulness, which in turn leads to the behavioural intention to use e‐travel sites.

The findings of the study suggest that web site information must be sufficiently provided, quickly expanded and constantly updated to maintain correct and current content to meet users' information needs as well as an appropriate assistance function to provide good levels of web‐based customer service. These attributes should satisfy visitors, making them likely to revisit e‐travel sites.

Little systematic applied research has been conducted on how age‐related cognitive impairments might affect older adults' usage of web service and this paper aims to fill some of that gap.

An analysis of the relationship between the cognitive changes of aging and the usage of web services. Supported by field research with the key stakeholders, including older adults and organisations that provide services for older adults. This consists of focus group sessions with key stakeholders and individual interviews with older adult users. Older adult users also complete an online form using a think aloud protocol. The data are analysed using a thematic content analysis technique.

Issues around older adults' relationship with technology and the challenges they face along with the strengths and weaknesses of online forms and means to improve them. In particular, there are issues of fear and frustration, inconsistency and visual clutter, and a feeling of neglect by service providers. Users also identify a strong need for human rather than machine support when struggling with the technology.

The findings only now being applied to an existing system in the Delivering Inclusive Access to Disabled and Elderly Members (DIADEM) project and it still needs to evaluate of usability of DIADEM. Further research also needs to consider the technology adoption model for system like DIADEM.

The findings have implications in form design and transaction delivery for online services.

The perception of neglect by service providers is new and this with the needs for consistency and for human support lead to novel approaches in the DIADEM system.

The purpose of this paper is to explore both accessibility and usability and examine the inhibitors and methods to evaluate site accessibility. Design techniques which improve end‐user access and site interactivity, demonstrated by practical examples, are also studied.

Assesses various web sites for accessibility and usability.

Criteria are determined by which to assess accessibility and usability of web sites.

Disability is an important consideration in the development of contemporary web sites. By understanding the needs of all users, not only those with disabilities, organisations may begin the process of advancing both accessibility and usability and integrating these elements into their web development strategies.

The purpose of this paper is to examine the way in which end user searching on the web has become the primary method of locating digital images for many people. This paper seeks to investigate how users structure these image queries.

This study investigates the structure and formation of image queries on the web by mapping a sample of web queries to three known query classification schemes for image searching (i.e. Enser and McGregor, Jörgensen, and Chen).

The results indicate that the features and attributes of web image queries differ relative to image queries utilized on other information retrieval systems and by other user populations. This research points to the need for five additional attributes (i.e. collections, pornography, presentation, URL, and cost) in order to classify web image queries, which were not present in any of the three prior classification schemes.

Patterns in web searching for image content do emerge that inform the design of web‐based multimedia systems, namely, that there is a high interest in locating image collections by web searchers. Objects and people images are the predominant interest for web searchers. Cost is a factor for web searching. This knowledge of the structure of web image queries has implications for the design of image information retrieval systems and repositories, especially in the area of automatic tagging of images with metadata.

This is the first research that examines whether or not one can apply image query classifications schemes to web image queries.

This column aims to investigate the possibilities of web services for the integration of information with relevant services.

This is a viewpoint paper.

This column encourages the exploration of web services based on careful analysis and semantic ontologies in order to provide relevant integration of services and information.

The rapid proliferation of web services – whether RESTful or SOAP based – offers many opportunities both internally and externally for libraries, but the adoption of web services needs to be tempered with careful planning and analysis.

The column offers some interesting suggestions for exploring theoretical options in the adoption of web service information and services. Some technical aspects of web service technology are discussed and then related to the core mission of librarianship, which is to assist patrons in navigating the great breadth of data available in increasing quantities via web service technology.

The purpose of this paper is to present research into the area of internet support for professional‐public communication through a deeper understanding of the role that a web site can provide in meeting the information needs of critically ill patients in intensive care units (ICUs). The communication between clinicians and members of the patient's family in the stressful ICU is modelled to give an integrated view of the situation and thereby allow for the incorporation of the views of all stakeholders on how the internet can meet this communication need.

The paper takes a broad, holistic, systemic approach that integrates the latest information and communications technology tools and processes with rich qualitative data from all stakeholder groups. The data are interpreted through the use of system dynamic modelling to visually conceptualise information flows and communication between clinicians and family members of patients.

The paper conceptualises, visualises and simulates the communication that takes place in complex stressful settings, such as, in ICUs thereby increasing the understanding of web‐support for professional‐public communication in the complex area of healthcare.

The broad approach of the paper has sacrificed, detailed and in depth analysis of all aspects of this issue which would require a much more extensive study.

The results have been of practical value to those developing a particular ICU web site and thus could inform others.

In addition to the findings, this paper is innovative in the way systems dynamics is used to model information flows. The results demonstrate the value of this technique for visualising and manipulating entire systems of this kind.

Investigates retailing on the Web and how the quality of goods and services are not as important as the process your customers go through to buy them. Posits that, in the future, companies with a successful development of Web channels will need to keep customers’ interaction on board as much as any other core business function. Sums up that Web sites that are successful have mastered retail processes and all the major details required to go forward.

The purpose of this research is to examine web accessibility initiative (WAI) guidelines for web accessibility so as to incorporate web accessibility in information systems (IS) curriculum.

The authors used the WebXact software accessibility evaluation tool to test the top pages of web sites of the 23 California State University (CSU) campuses in order to identify the level of compliance to federal standards. The authors also designed and conducted a questionnaire to survey the students who were enrolled in the first web development course at CSU, Dominguez Hills to access their knowledge and skills in various web accessibility topics.

The research findings show that the majority of the CSU campuses' top web pages failed to meet WAI guidelines at some point. Moreover, two‐thirds of the students who responded to the survey have no knowledge of web accessibility topics included in the questionnaires. The results indicate that IS programs failed to incorporate accessibility in their curricula and produce web developers with the skills and knowledge in web accessibility.

The limitation of this research is that the sample size is small. The authors intend to increase the number of universities' web site in the test and survey all students in the IS program in a future study.

This research is background work that will help the authors to incorporate accessibility topics in their web development courses that include web accessibility basic concepts, universal design, Section 508 of the US Rehabilitation Act, web content accessibility guidelines, WAI guidelines for web accessibility, and web accessibility testing tools.

This research improves the current state of web accessibility in curriculum higher education.
