We have used this system to integrate and effectively federate 15 Indiana county map servers with Google map images and state-wide ortho-photography data. Our approach is an example of the so-called Web 2.0 style of development, in which we integrate external, third party services into a higher level service. This approach also allows for lightweight client development using relatively simple JavaScript programming libraries. We demonstrate this by building a Google Map client interface to our tile server. Finally, we discuss our initial efforts to make collaborative clients using a shared event model that captures and broadcasts browser events to other, listening browsers.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133001024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we consider joint battlespace infosphere (JBI) or JBI-like collaborative information sharing environments, where the quality of published information often depends on the quality of the contributing information and of the sources that publish them. However, as the environment becomes larger and more diverse, it is becoming increasingly difficult for human operators to assess the quality of information from various data sources. To address this challenge, we develop AIMS, an agent-based information management system, to manage the quality of information in JBI-like environments, e.g., information trustworthiness. In our approach, each operator is associated with a software agent, called client agent. The client agent enables its operator to interact with the JBI repository via the services of query, publish, and subscribe. Moreover, the client agent collaborates with other agents to assess and learn the trustworthiness of information and the reliabilities of corresponding data sources from its pedigree and the feedback from operators.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"29 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124713907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to investigating the impacts of perceived ease of use (PEOU), perceived usefulness (PU), and perceived Internet content (PIC) on studentspsila usage of the Internet, it analyzed the direct impacts of external variables such as gender, educational background, income level, self-reported measure of computer knowledge, Internet cost, and Internet availability on Internet usage and their moderating role in the relationship between PEOU, PU, and PIC and Internet usage. To test the hypothesized relationships, we extended the research model that was developed by [1] was extended by adding more factors to it. To validate the research model, data was collected from 169 students from Chile and 194 students from United Arab Emirates (UAE). The results showed that only PU was a significant predictor of Internet usage for both Emirates and Chilean samples. Additionally, while gender significantly impacted Emirates studentspsila usage of Internet, self-reported knowledge about computers significantly impacted Chilean studentspsila usage of the Internet. Income level was the only significant moderator for both countries. PU affected usage of the Internet more positively for students with high income level than it did for those students with low income.

Based on these lessons we present five general principles for constructing knowledge-rich systems that can collaborate with one another.

We believe that the current tools these students can use call for a drastic change in traditional learning paradigms by either the instructor or the pupil. To fill this gap, we propose our tool, taking notes together (TNT), as a collaborative note taking tool that will help in equalizing the classroom for students with disabilities. This tool allows students to collaboratively tag classroom lecture/discussion in real time through synchronized transcription and audio recording. TNT provides a visualization that highlights the important classroom points and we argue facilitates better recall and a deeper understanding of the classroom material. Through our evaluation we were able to prove that all students can benefit from this tool. We also present a case study of one student with ADD and how they benefited. The tool makes the learning experience, particularly for students with special needs like LD and ADD, less stressful while still being active in the note-taking.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114168521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a multi-agent collaboration method based on the concept of information fusion in which the tasks can be divided quickly without task overlapping and resource conflicting. In this model we classify the agents into two categories: sensor agents and decision agents. Sensor agents with the abilities of sensing and action convert the raw sensor information into a definite protocol and transmit them to decision agents. Decision agents adopt a method based on dynamic Bayesian networks to infer the situation assessment which is reliable for decision making from large quantities of sensor information, and then retrieve a best action set which will be sent to sensor agents to execute. This model has applied effectively in RoboCupRescue simulation competition.","PeriodicalId":363805,"journal":{"name":"2007 International Symposium on Collaborative Technologies and Systems","volume":"634 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122949199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
