DocCube: Multi-dimensional visualisation and exploration of large document sets

Josiane Mothe, Claude Chrisment, Bernard Dousset, Joel Alaux
2003 Journal of the American Society for Information Science and Technology  
Each CH corresponds to a facet of the documents users can be interested in. Users browse these CHs in order to specify and refine their information needs.  ...  An important element of the approach we introduce is the use of concept hierarchies (CHs) in order to structure the document collection.  ...  Knowledge on relationships between the authors and the topics of the documents ; the strength of these links and their evolution in the time can also be discovered.  ...

The Effects of Web Logs and the Semantic Web on Autonomous Web Agents [chapter]

Michael P. Evans, Richard Newman, Timothy A. Millea, Timothy Putnam, Andrew Walker
2004 Lecture Notes in Computer Science  
We conducted a Web crawl of 160 000 pages in which the link structure of the Web is compared with that of several thousand blogs.  ...  Results show that the two link structures are significantly different. We analyse the differences and infer the likely effect upon the performance of existing and future Web agents.  ...  This evolution is reflected in the Web's hyperlink structure, the set of all Web pages and their hyperlinks known as the Web Graph, which is fuzzy in nature, and constantly changing over several different  ...

G. Almpanidis, C. Kotropoulos, I. Pitas
2007 Information Systems  
The number of vertical search engines and portals has rapidly increased over the last years, making the importance of a topic-driven (focused) crawler self-evident.  ...  In this paper, we develop a latent semantic indexing classifier that combines link analysis with text content in order to retrieve and index domain-specific web documents.  ...  Athanasios Papaioannou for his contributions in the implementation of the PLSI algorithm.  ...

Christian Damsgaard Jensen, Povilas Pilkauskas, Thomas Lefévre
2011 Journal of Information Processing  
The Wikipedia is a web-based encyclopedia, written and edited collaboratively by Internet users.  ...  We identify a number of requirements that a classification scheme must meet in order to be useful in the context of the WRS and present an evaluation of four existing knowledge classification schemes with  ...  The Open Directory project is owned by Netscape, but the directory is maintained by a community of volunteer editors who are responsible for the inclusion of sites into the web directory.  ...

Observation-Driven Configuration of Complex Software Systems [article]

Aled Sage
2010 arXiv   pre-print
Complexity arises from the size of software systems and the wide variety of possible operating environments: the increasing choice of platforms and communication policies leads to ever more complex performance  ...  The novel contribution here is an industrial case study, applying the combination of ACT and Taguchi Methods to DC-Directory, a product from Data Connection Ltd (DCL).  ...  A secondary use of the predictive model for DC-Directory was to rank untested combinations in terms of quality, using estimates of the main effects and a selection of interaction effects.  ...

Precision agriculture research in sub-Saharan Africa countries: a systematic map

Justine M. Nyaga, Cecilia M. Onyango, Johanna Wetterlind, Mats Söderström
2021 Precision Agriculture  
Results show that most of the studies were conducted in countries with socio-economic and technological advancement, mainly South Africa followed by Nigeria and Kenya.  ...  However, based on authorship of the articles, it appears that most of the studies conducted in SSA on precision agriculture have either involved or depended on non-African researchers.  ...  Jeremiah Okeyo from the University of Embu helped in generating the geographical distribution map of precision agriculture studies per country in SSA.  ...

Can we find documents in web archives without knowing their contents?

Khoi Duy Vo, Tuan Tran, Tu Ngoc Nguyen, Xiaofei Zhu, Wolfgang Nejdl
2016 Proceedings of the 8th ACM Conference on Web Science - WebSci '16  
These collections are valuable to explore the past of the Web, but their value can only be uncovered with effective access and exploration mechanisms.  ...  We perform a first study to compare the usefulness of non-content evidences to Web archive search, where the evidences are mined from the metadata of file headers, links and URL strings only.  ...  This work was funded by the ERC Advanced Grant ALEXANDRIA (under the grant No. 339233). We thank the reviewers for the fruitful discussion and suggestions on future work.  ...
