Early analysis approaches focused primarily on accesses to Web documents as recorded in Web server logs. More recent techniques create a model of a site, and the natural modeling approach is to use a directed graph, where pages are denoted by nodes and links are modeled by edges. The process of creating the model and then analyzing the corresponding visitor traffic, however, is fraught with difficulties.

Sets of documents that are changed together during the translation process are uncovered and documented to support future evolution of the system. A sequential-pattern mining technique is used to uncover the patterns from Subversion repositories. The approach is applied to the open source KDE system. KDE maintains documentation for over fifty different natural languages and presents a prime example of the problem. Characteristics of the uncovered patterns such as size, frequency, and occurrences within a single language or across multiple languages are discussed. Such patterns help provide insight as to the effort required in retranslation due to a change in the documentation and help user communities estimated the progress of documentation in their respective languages","PeriodicalId":174396,"journal":{"name":"2006 Eighth IEEE International Symposium on Web Site Evolution (WSE'06)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121418782","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}

Kontogiannis","doi":"10.1109/WSE.2006.13","DOIUrl":"https://doi.org/10.1109/WSE.2006.13","url":null,"abstract":"Model-driven techniques have been proposed and promoted by the Software Engineering community over the past few years as a mechanism for streamlining the design, implementation and evolution of large software applications. The basic idea behind model-driven techniques is that, design artifacts of large software applications can be represented as a collection of models which can be consequently transformed and evolved to generate specific design artifacts and even source code that complies with specific programmatic paradigms and patterns. Even though model-driven frameworks have caught the attention of the software engineering community as a way to increase programmers' productivity and overall system robustness through the disciplined manipulation and transformation of models and ultimately code generation, they have remained so far only in the form of \"guidelines\" or \"standard practices\". In this respect, important questions regarding to what types of models are required for system representation, how transformations are encoded and enacted, how model constraints are denoted and validated, and how source code is generated, is left to software vendors, software architects and software developers to further design and implement. In this keynote presentation we will focus on the challenges, issues, emerging research topics and practical examples pertaining to the use of model-driven techniques for the design, analysis and evolution of network-centric, web-based applications. Some of these challenges in such systems include the use of multi-language paradigms, the problem of maintaining consistency between various models during system evolution, dealing with underlying technology changes, and facilitating end-product customizability.","PeriodicalId":174396,"journal":{"name":"2006 Eighth IEEE International Symposium on Web Site Evolution (WSE'06)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123635654","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}

For example, filename extensions and parameter names can reveal volatile implementation details. As a result, when Website implementations change, links between pages break. Bookmarks and code that generates URLs often break as well. In this paper, we present two tools for information-hiding URLs. An information-hiding URL uses an alias to identify a Web resource and appends parameter values into the hierarchical structure of the URL. The InformationHidingFilter uses a Java Servlet filter to facilitate the use of information-hiding URLs with JSP/Servlet Web applications. Given a request, the filter identifies the JSP or Servlet being requested and identifies parameter values contained in the information-hiding URL. Required values not provided in the URL are automatically substituted with default values specified by the Web developer. Thus, old links remain valid even when the Website changes and new parameters have been added to the page. The InformationHidingChecker helps Web developers adhere to information hiding by helping them identify JSPs or Servlets that lack URL information for the InformationHidingFilter or lack default values for parameters. We also discuss the performance cost of using information-hiding URLs","PeriodicalId":174396,"journal":{"name":"2006 Eighth IEEE International Symposium on Web Site Evolution (WSE'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129221611","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}

Maintainers have to match their mental models with the different representations these tools provide. In this paper, we present a novel approach that addresses this issue by providing a consistent ontological representation for both source code and documentation. The ontological representation unifies information from various sources, and therefore reduces the maintainers' comprehension efforts. In addition, representing software artifacts in a formal ontology enables maintainers to formulate hypotheses about various properties of software systems. These hypotheses can be validated through an iterative exploration of information derived by our ontology inference engine. The implementation of our approach is presented in detail, and a case study is provided to demonstrate the applicability of our approach during the architectural evolution of a Web site content management system","PeriodicalId":174396,"journal":{"name":"2006 Eighth IEEE International Symposium on Web Site Evolution (WSE'06)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129725044","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}

These choices are to be verified, confirmed or refused not only against design quality and hypotheses, but mostly against actual usages. The actual usages of a website are of the utmost importance to infer and understand interests, goals and styles of users, and are to be interpreted in order to maintain, refine and enhance the website itself. It is neither a one-off nor a one-way path, but a continuous dialogue among different people and stakeholders, requiring endless hypothesizing and testing of hypotheses (e.g.: did they leave that page soon because it wasn't relevant to them, or because they found it so relevant to print it out for further reading? Did they leave the website after accessing that page because their interest was fully satisfied, or because they didn't find anything useful? Is a page seldom accessed because it is not that interesting or because there is a cumbersome navigation? etc.). The answers to those questions force to re-think communication strategies, as well as all other design dimensions. Moreover, an online application yields to many further exchanges, like buying, voting, subscribing, chatting, gambling, reserving, sending emails etc., activities that leave traces offering insights on our readership/users/clients, and need to be interpreted and to feed back into the website maintaining and improving processes.","PeriodicalId":174396,"journal":{"name":"2006 Eighth IEEE International Symposium on Web Site Evolution (WSE'06)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114628863","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}

They are needed when users have visual impairments, or not much attention can be paid to a screen (possibly also a tiny one). Web sites, today, and even most mobile applications, use, above all, the \"visual channel\" to communicate content, navigation/interaction capabilities and \"interface messages \" (such as orientation, application structure, page structure, priorities of elements on the page, ...). However, requirements for aural Web sites, despite their relevance (e.g. W3C- WAI initiatives), are poorly addressed by current accessibility guidelines. Most of the focus, in fact, seem to lay upon basic accessibility issues (such as the fact that each image should have a semantically equivalent text), or about technicalities (such as how to avoid the use of tables for the pages layout). This paper discusses salient requirements for aural Web sites and their implications upon both the user experience and the Web sites evolution.

The process first computes the distances between the Web pages and then identifies similar pages through the winner takes all clustering algorithm. Two different instances of the process are presented to identify similar pages at structural and content level, respectively. The first instance encodes the page structure into a string and then uses the Levenshtein algorithm to achieve the distances between pairs of pages. On the other hand, to group similar pages at content level we use the latent semantic indexing to produce the page representations as vectors in the concept space. The Euclidean distance is then computed between the vectors to achieve the distances between the pages to be given as input to the adopted clustering algorithm.
