In China, there is a large amount of data about agricultural products price released by thousands of agricultural websites on the Internet. These records are basically displayed in the form of text, table, and statistics chart but location information cannot be displayed graphically. Rich client and WebGIS techniques can improve representation of agricultural products price and help to provide effective technological solutions for increasing data. First, we describe the methods of standardizing agricultural products price data, which is crawled from agricultural websites through vertical search engine. Forward maximum matching algorithm is then explained and applied for spatializing data. After that, technologies of WebGIS based on rich client (JavaScript/Ajax and Flex) are summarized and analyzed and the map visualization methods of agricultural products price are presented, taking Baidu Map API and ArcGIS API for Flex for example. The methods can provide visual, interactive, user-friendly representation of agricultural products price data in geography information system as well as share visualization services through Internet or Intranet to improve data exchange and utilization. Compared to traditional WebGIS, WebGIS based on RIA improves user satisfaction and increases response speed. The results demonstrate that WebGIS by using RIA technology is a feasible solution method for map visualization of agricultural products price.

Forecasting the prices of hogs has always been a popular field of research. Such information has played an essential role in decision-making for farmers, consumers, corporations, and governments. It is hard to predict hog prices because too many factors can influence them. Some of the factors are easy to quantify, but some are not. Capturing the characteristics behind the price data is also tricky considering their non-linear and non-stationary nature. To address these difficulties, we propose Heterogeneous Graph-enhanced LSTM (HGLTSM), which is a method that predicts weekly hog price. In this paper, we first extract the historical prices of necessary agricultural products in recent years. Then, we utilize discussions from the online professional community to build heterogeneous graphs. These graphs have rich information of both discussions and the engaged users. Finally, we construct HGLSTM to make the prediction. The experimental results demonstrate that forum discussions are beneficial to hog price prediction. Moreover, our method exhibits a better performance than existing methods.

Purpose – The main aim of this paper is to identify whether user demographic characteristics, computer skills, user education, user assistance and user-friendly OPAC (online public access catalog) have an impact on their satisfaction in the context of users in an Indian university setting. Design/methodology/approach – The survey method was utilized and a questionnaire was designed to collect data. The study is based on a sample of the 384 questionnaires from the three universities located in the Union Territory of Chandigarh and Punjab State. To analyze the data collected, SPSS package (version 14.0) was used, and also to produce requisite cross-tabulations. Chi-square testing was performed to determine the association of user satisfaction with the variables covered in the study. Findings – The findings highlighted that overall there was a low degree of satisfaction among the users. With the exception of academic majors, in general, there were no significant differences between satisfaction and user demographic characteristics. Overall satisfaction was significantly higher for those who were possessed with adequate knowledge on OPAC, and had received staff assistance, as well as necessary education on OPAC. The study showed that satisfaction with ease of usage of OPAC was higher. It was also found that users were well-equipped with computers and had attained skills while frequently searching the web, however, it was also revealed that mere possession of computer skills was not sufficient for efficient use of OPAC, resulting in the attainment of a high level of satisfaction. Originality/value – The paper brings out the fact of how user demographic characteristics, computer skills, user education, user assistance, and user-friendly OPAC, influence user satisfaction in a university educational set up. The findings will be beneficial for increasing user satisfaction levels in order to retain existing OPAC users because OPAC will continue to be a necessary tool for accessing quality academic information available in both print and electronic format.

We assessed a data security system using biometric fingerprint techniques and smartcards to control access to a teleradiology system. Clinical cases were initially discussed between the referring physician and radiologist in Tyrol using a video-phone. Subsequent correspondence, including the transmission of images between the referring physician and the radiologist, was carried out by email using the security system to prevent unauthorized access to patient information. Seventy-eight teleradiology sessions were conducted using this data security system. Speed and stability of data exchange were unaffected by the additional security feature. The average log-on time to the system was 7.8 s. The average training time on how to use the system was 15 min. The radiologist was able to issue a final patient report using the system within 1.5 of the initial contact. The data security feature was user-friendly and did not hinder the normal teleradiology consultation.

With the increasing use of e-business web sites, users are often asked to select a menu-item from a large numbers of options. In this research, the pull-down menu, fisheye menu and grid menu were tested to compare the performance time, error rate, user satisfaction, simplicity, user friendliness, usefulness, and overall user preference of each menu type. The grid menu was more efficient in selection speed than the pull-down and fisheye menus when the number of menu-items was 50 and 100. The time needed to choose a menu-item with a grid menu was less affected by the size of menu and the physical location of an item within a menu. The pull-down and the grid menus were considered to be more satisfactory, simple, user friendly, and useful than the fisheye menu. 42.3 percent of subjects indicated that the grid menu was their preferred selection tool among the menus. The grid menu is an efficient and robust alternative menu choice for small and middle size menu lists.

Since the late 1980s, the Child Language Data Exchange System (CHILDES) has defined the state of the art of collection, analysis, archiving, and data sharing of transcriptions of children's language. Starting from scratch in 1987, Brian MacWhinney, along with many other leaders in child language, developed highly useful tools for the computerization of transcripts and their analysis. I have used the transcription conventions and analysis programs since 1989 and have seen the system evolve from a simple DOS-based program to one that handles much broader and more complex analyses within more user-friendly Windows and Macintosh platforms. This latest (third) edition of the manual that accompanies the CHILDES system reflects a more stable version of the Conventions for Human Analysis of Transcripts (CHAT) and Child Language Analysis (CLAN) programs than prior editions, which felt like works in progress. This version is written as a finished product with procedures and programs that have settled down into stable patterns of operation.

AbstractBackground and aimsMinirhizotrons are commonly used to study root turnover which is essential for understanding ecosystem carbon and nutrient cycling. Yet, extracting data from minirhizotron images requires intensive annotation effort. Existing annotation tools often lack flexibility and provide only a subset of the required functionality. To facilitate efficient root annotation in minirhizotrons, we present the user-friendly open source tool rhizoTrak.Methods and resultsrhizoTrak builds on TrakEM2 and is publically available as Fiji plugin. It uses treelines to represent branching structures in roots and assigns customizable status labels per root segment. rhizoTrak offers configuration options for visualization and various functions for root annotation mostly accessible via keyboard shortcuts. rhizoTrak allows time-series data import and particularly supports easy handling and annotation of time series images. This is facilitated via explicit temporal links (connectors) between roots which are automatically generated when copying annotations from one image to the next. rhizoTrak includes automatic consistency checks and guided procedures for resolving conflicts. It facilitates easy data exchange with other software by supporting open data formats.ConclusionsrhizoTrak covers the full range of functions required for user-friendly and efficient annotation of time-series images. Its flexibility and open source nature will foster efficient data acquisition procedures in root studies using minirhizotrons.

Introduction A needs analysis was conducted to investigate barriers to optimal emergency asthma care in rural Australia. The findings revealed that utilisation of ambulance services for asthma was suboptimal despite improved outcomes in cases where paramedic intervention was sought. Asthma Foundations of Australia funded the development, implementation and evaluation of the `Ambulances for Asthma’ program to address this issue. This paper aims to describe the role the community played in the development and evaluation of the program. The key domains of pedagogy, format, usability, navigation, interactivity and delivery have been utilised to provide a framework for program review. Methods A Project Steering Group comprising key stakeholders was convened to establish best practice management of out-of-hospital asthma in rural areas. A multimedia education package incorporating a website, brochure/CD and poster was developed. Human-computer interface testing and focus groups were used to refine the program pre-implementation. Evaluation questionnaires and focus groups were utilised post implementation. Results The vast majority (76%) of respondents agreed that the program was user friendly. A large proportion (90.5%) of participants felt more confident with their asthma knowledge and 64% of the participants were more likely to call an ambulance for their asthma as a result of the education package. Conclusion The use of community based feedback to develop and refine the `Ambulances for Asthma’ program resulted in high levels of user satisfaction. The findings show that the program has potential as a decision aid for people with asthma in rural Australia.

A Web portal is a site that aggregates information from multiple sources on the World Wide Web and organizes this material in an easy user-friendly manner. Portals usually consist of a search engine, e-mail, news, and interactive chat facilities. The two main types of portals are horizontal and vertical portals. A horizontal portal is a Web site that provides consumers access to a number of different sites in terms of content and functionality. A vertical portal focuses on a specific community of users who share a common interest. In this chapter we investigate the impact of user characteristics such as gender, age, experience, and Web use on user satisfaction with Web portals. In our study we are unable to detect any differences in satisfaction based on gender. We find that the users with seven to 10 years of work experience are most satisfied with Web portals, while users with more than 10 years work experience report least satisfaction with Web portals. We also find that users that use Web portals the least (30 to 60 minutes per week) are least satisfied with them. Users of vertical (or customer community) portals are always more satisfied than users of horizontal (or mega) portals.


Our existing society is totally dependent on web search to fulfill our daily requirements. Therefore millions of web pages are accessed every day. To fulfill user need number of websites and webpages are added .The growing size of web data results to the difficulty in attaining useful information with a minimum clicks. This results to the acquisition of personalization a major place in Web search. But the use of personalization breaches privacy in searching. Personalization with privacy is leading issue in current web environment. This paper aims at user satisfaction by using user identification based personalization approach in web search engine. Beside personalization the proposed model creates privacy during personalization. The proposed system will prove to be user friendly with less efforts and privacy concern.
