The problem is difficult because: (i) the textual content of blogs is often noisy, (ii) comments do not always target passages of the posts and, (iii) comments are not equally useful for identifying important passages. We have developed a system for selecting commented passages which takes as input blog posts and their comments and delivers, for each post, the sentences of the post which are the most commented and/or the most discussed. Our approach combines three steps to identify commented passages of a post. The first step is to remove the complexity of processing the contents of posts and comments using heuristics adapted to the language of the blog. The second step is to find useful comments and assigns them a degree of relevance using a model automatically built and validated by an expert. The third step is to identify important passages using relevant comments. We conducted two experiments to evaluate the usefulness and the effectiveness of our approach. The first study show that in only 50% of the posts, the most commented sentence elicited by our approach corresponds to the post extract generated using generic summarization. In the second study, human participants confirmed that, in practice, selected passages are frequently commented passages.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"204 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127032953","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}

Over the past few years, the IEEE-LOM standard has dominated the metadata world in e-learning applications. However, with the advent of the Semantic Web, e-learning applications are beginning to evolve their metadata representation from these standards by adding semantic structure or by converting entirely to semantic representations of structure. This shift enables the implementation of a range of new tools which can reason over the metadata, providing added value from the stored data. This review paper summarizes this evolution of metadata used in e-learning applications from standards to semantic representation.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129222871","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}

The knowledge structures created should fit into the real world environment and reflect the common ground reached and evolved in the cooperation process of the knowledge workers. In order to facilitate the development of shared understanding among knowledge workers, Herbert Clark's theory on language use and Jean Piaget's cognitive theory are applied to the use of hypermedia language in cooperative work settings. To make the theories easier to apply, a conceptual framework is derived from them, which can inform the design and comparison of cooperative hypermedia systems and the use of hypermedia in cooperative settings.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124322510","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}

Web lectures are easier to produce and therefore large amounts of material become accumulated in a short time. The recordings are significantly less structured than traditional web based learning content and they are time based media. Both the lack of structure and their time based nature pose difficulties for navigation in web lectures. The approach presented in this paper applies the basic concept of social navigation to facilitate navigation in web lectures. Social navigation support has been successfully employed for hypertext and picture augmented hypertext in the education domain. This paper describes how social navigation can be implemented for web lectures and how it can be used to augment existent navigation features.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125123561","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}

A browser built using this framework would be a client-side system that downloads, in real time, past page versions from Web archives for their customized presentation. It would use passive browsing, change detection and change animation to provide a smooth and satisfactory browsing experience. We propose a meta-archive approach for increasing the coverage of past Web pages and for providing a unified interface to the past Web. Finally, we introduce query-based and localized approaches for filtered browsing that enhance and speed up browsing and information retrieval from Web archives.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122536810","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 examine how communities can be discovered through interconnected blogs as a form of social hypertext [14]. We propose a method and model that detects structures of community in the social network of blogs by integrating McMillan and Chavis' sense of community [26] along with network analysis [8, 11]. From the model, we measure community in the blogs by aligning centrality measures from social network analysis [17] with measures of sense of community obtained using behavioural surveys. We then illustrate the use of this approach with a case study built around an independent music blog. The strength of community measures were found to be well aligned with the network structure, based on centrality measures. Even though the sample size from the case study was small, once the structure and measure of communities are calibrated according to our social hypertext model, communities can be automatically found and measured for other blogs without the need for behavioural surveys.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"426 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116614999","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}

A large number and variety of blogs, like personal journals or commentaries, are available for general consumption. However, effective indexes and navigation structures (like the table of content in a book) are not available for blogs. Therefore, it is generally not possible to navigate among entries in a given collection of blog entries in an informed manner. This paper focuses on the segmentation of entries in filter-type [9] blogs, with the aim of using this information for developing hypertext and navigational helps. In particular, we are interested in the analysis of topic development patterns that can provide information about not only the entries themselves, but how these entries develop and relate to each other. The proposed algorithm, CUTS, maps entries into a curve in a way that makes apparent a variety of topic development patterns. We then use curve analysis for automatic segmentation of topics. The resulting base topic segments are classified into different topic development patterns that can be visualized and indexed. Experimental results show that the proposed technique has very good performance in identifying boundaries in text streams, especially filter style blogs, versus existing schemes. Furthermore, compared with other topic segmentation methods, the proposed mechanism highlights not only topic boundaries, but also topic development patterns.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124377337","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}

Unfortunately, information seeking in this complex hypermedia environment is generally not an easy task. The potentially complex task of information seeking in the WWW is further complicated when the end-user is blind or visually impaired (VI). Usually, web pages are created without taken accessibility into account and without using HTML markup correctly to express the functional structure of documents. Both facts pose a lot of problems to VI during information seeking in the web. In this paper we discuss problems related to this issue and how the information seeking process in the WWW could become more effective and efficient for the VI. We also present an ongoing research effort, inspired from the idea of Semantic Web, aiming to enhance browsing efficiency as a result of rationalizing the way VI browse the WWW.","PeriodicalId":134809,"journal":{"name":"UK Conference on Hypertext","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130627977","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}
