These pages are often referred to as the hidden Web or the deep Web. Since there are no static links to the hidden Web pages, search engines cannot discover and index such pages and thus do not return them in the results. However, according to recent studies, the content provided by many hidden Web sites is often of very high quality and can be extremely valuable to many users. In this paper, we study how we can build an effective hidden Web crawler that can autonomously discover and download pages from the hidden Web. Since the only \"entry point\" to a hidden Web site is a query interface, the main challenge that a hidden Web crawler has to face is how to automatically generate meaningful queries to issue to the site. We provide a theoretical framework to investigate the query generation problem for the hidden Web and we propose effective policies for generating queries automatically. Our policies proceed iteratively, issuing a different query in every iteration. We experimentally evaluate the effectiveness of these policies on 4 real hidden Web sites and our results are very promising. For instance, in one experiment, one of our policies downloaded more than 90% of a hidden Web site (that contains 14 million documents) after issuing fewer than 100 queries","PeriodicalId":248721,"journal":{"name":"Proceedings of the 5th ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL '05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129736370","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}

While these approaches have so far built reasonable size libraries, they can suffer from having only a portion of the documents from specific publishing venues. We propose to use alternative online resources and techniques that maximally exploit other resources to build the complete document collection of any given publication venue. We investigate the feasibility of using publication metadata to guide the crawler towards authors' homepages to harvest what is missing from a digital library collection. We collect a real-world dataset from two Computer Science publishing venues, involving a total of 593 unique authors over a time frame of 1998 to 2004. We then identify the missing papers that are not indexed by CiteSeer. Using a fully automatic heuristic-based system that has the capability of locating authors' homepages and then using focused crawling to download the desired papers, we demonstrate that it is practical to harvest using a focused crawler academic papers that are missing from our digital library. Our harvester achieves a performance with an average recall level of 0.82 overall and 0.75 for those missing documents. Evaluation of the crawler's performance based on the harvest rate shows definite advantages over other crawling approaches and consistently outperforms a defined baseline crawler on a number of measures","PeriodicalId":248721,"journal":{"name":"Proceedings of the 5th ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL '05)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122649659","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 1999, the American Association for the Advancement of Science (AAAS) Directorate for Education and Human Resources (EHR) Programs and Science's Signal Transduction Knowledge Environment (STKE) - with 11 other professional societies and coalitions for biological sciences - established the BiosciEdNet (BEN) Collaborative. Since its inception, BEN has grown from its original 11 to 24 Collaborators. Currently, the digital library collections of BEN Collaborators provide a rich array of materials for undergraduate biological sciences educators, including ones that prepare K-12 teachers. BEN Collaborators are building digital collections that are inclusive of all educators and students. In summary, BEN has already developed tools and services that can be shared to leverage technologies across societies, coalitions, and collections affiliates. BEN has a documentation site - http://www.biosciednet.org/project_site/ that includes all its technical standards and specifications. For long-term sustainability the BEN Collaborative goal is to design and develop digital library collections that are valued by the members of professional societies, thereby eventually ensuring inclusion in the ongoing operating budgets of societies.

The Climate Change Collection is thematic collection of digital resources relating to the topic of global climate change and natural climate variability designed as a pilot project for reviewing the scientific quality and pedagogical potential of selected digital resources using a focused and streamlined approach. The collection offers a case-study in integrating research and education through the collaborative efforts of an interdisciplinary review team made up of professionals from the fields of climate research, geoscience education, cognitive psychology, and evaluation. Each participant received a stipend for their involvement in the process. Designed as an experiment in streamlined collection development, it is anticipated that the experience of the Climate Change Collection effort will help inform future digital library review and collection-building efforts","PeriodicalId":248721,"journal":{"name":"Proceedings of the 5th ACM/IEEE-CS Joint Conference on Digital Libraries (JCDL '05)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116361097","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}
