Mementomap: A Web Archive Profiling Framework For Efficient Memento Routing, Sawood Alam
Mementomap: A Web Archive Profiling Framework For Efficient Memento Routing, Sawood Alam
Computer Science Theses & Dissertations
With the proliferation of public web archives, it is becoming more important to better profile their contents, both to understand their immense holdings as well as to support routing of requests in Memento aggregators. A memento is a past version of a web page and a Memento aggregator is a tool or service that aggregates mementos from many different web archives. To save resources, the Memento aggregator should only poll the archives that are likely to have a copy of the requested Uniform Resource Identifier (URI). Using the Crawler Index (CDX), we generate profiles of the archives that summarize their …
A Framework For Verifying The Fixity Of Archived Web Resources, Mohamed Aturban
A Framework For Verifying The Fixity Of Archived Web Resources, Mohamed Aturban
Computer Science Theses & Dissertations
The number of public and private web archives has increased, and we implicitly trust content delivered by these archives. Fixity is checked to ensure that an archived resource has remained unaltered (i.e., fixed) since the time it was captured. Currently, end users do not have the ability to easily verify the fixity of content preserved in web archives. For instance, if a web page is archived in 1999 and replayed in 2019, how do we know that it has not been tampered with during those 20 years? In order for the users of web archives to verify that archived web …
Aggregating Private And Public Web Archives Using The Mementity Framework, Matthew R. Kelly
Aggregating Private And Public Web Archives Using The Mementity Framework, Matthew R. Kelly
Computer Science Theses & Dissertations
Web archives preserve the live Web for posterity, but the content on the Web one cares about may not be preserved. The ability to access this content in the future requires the assurance that those sites will continue to exist on the Web until the content is requested and that the content will remain accessible. It is ultimately the responsibility of the individual to preserve this content, but attempting to replay personally preserved pages segregates archived pages by individuals and organizations of personal, private, and public Web content. This is misrepresentative of the Web as it was. While the Memento …
To Relive The Web: A Framework For The Transformation And Archival Replay Of Web Pages, John Andrew Berlin
To Relive The Web: A Framework For The Transformation And Archival Replay Of Web Pages, John Andrew Berlin
Computer Science Theses & Dissertations
When replaying an archived web page (known as a memento), the fundamental expectation is that the page should be viewable and function exactly as it did at archival time. However, this expectation requires web archives to modify the page and its embedded resources, so that they no longer reference (link to) the original server(s) they were archived from but back to the archive. Although these modifications necessarily change the state of the representation, it is understood that without them the replay of mementos from the archive would not be possible. Unfortunately, because the replay of mementos and the modifications made …
Avoiding Spoilers On Mediawiki Fan Sites Using Memento, Shawn M. Jones
Avoiding Spoilers On Mediawiki Fan Sites Using Memento, Shawn M. Jones
Computer Science Theses & Dissertations
A variety of fan-based wikis about episodic fiction (e.g., television shows, novels, movies) exist on the World Wide Web. These wikis provide a wealth of information about complex stories, but if readers are behind in their viewing they run the risk of encountering spoilers" -- information that gives away key plot points before the intended time of the show's writers. Enterprising readers might browse the wiki in a web archive so as to view the page prior to a specific episode date and thereby avoid spoilers. Unfortunately, due to how web archives choose the "best" page, it is still possible …
