Document normalization revisited

Abdur Chowdhury, M. Catherine McCabe, David Grossman, Ophir Frieder
2002 Proceedings of the 25th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '02  
Cosine Pivoted Document Length Normalization has reached a point of stability where many researchers indiscriminately apply a specific value of 0.2 regardless of the collection.  ...  Our efforts, however, demonstrate that applying this specific value without tuning for the document collection degrades average precision by as much as 20%.  ...  Introduction The cosine measure normalizes document length so that long documents are not favored simply because they have more terms.  ...

As a consequence, the trace of ∇u k on ∂Ω is well defined in L 1 (∂Ω) N (at least) and therefore the trace of ∂ ν u k = ∇u k · ν is well defined as well (ν= unit exterior normal to ∂Ω).  ...

Revisiting read wear

Jason Alexander, Andy Cockburn, Stephen Fitchett, Carl Gutwin, Saul Greenberg
2009 Proceedings of the 27th international conference on Human factors in computing systems - CHI 09  
In this paper, we show that people frequently return to previously-visited regions within their documents, and that scrollbars can be enhanced to ease this task.  ...  Our analysis shows that region revisitation is a common activity that can be supported with relatively short recency lists.  ...  tools other than the normal scrollbar are used very little, and that short recency lists can contain most locations that people will revisit. 2.  ...

Implicit bookmarking: Improving support for revisitation in within-document reading tasks

Chun Yu, Ravin Balakrishnan, Ken Hinckley, Tomer Moscovich, Yuanchun Shi
2013 International Journal of Human-Computer Studies  
We explore improving support for revisitation in documents by automatically generating bookmarks based on users' reading history.  ...  After showing that dwell time and number of visits are not appropriate for predicting revisitations in documents, we model the high-level reading task as a sequence of reading blocks and recognize long-distance  ...  Right: revisit possibility as a measure of normalized dwell time.

Incorporating revisiting behaviors into click models

Danqing Xu, Yiqun Liu, Min Zhang, Shaoping Ma, Liyun Ru
2012 Proceedings of the fifth ACM international conference on Web search and data mining - WSDM '12  
If a user clicks on a higher ranked document after having clicked on a lower-ranked one, we call this scenario a revisiting pattern, and we believe that the revisiting patterns are important signals regarding  ...  The experimental results show that the THCM model achieves a significant improvement in the Normalized Discounted Cumulative Gain (NDCG), the click perplexity and click distributions metrics.  ...  Given a position i, it may be examined from the (i-1)-th document, and also be revisited from lower documents.  ...

Semantic History Map: Graphs Aiding Web Revisitation Support

Jakub Šimko, Michal Tvarozek, Maria Bielikova
2010 2010 Workshops on Database and Expert Systems Applications  
We present a novel approach intended to reduce user effort required to retrieve and/or revisit previously discovered information by exploiting web search and navigation history.  ...  The Map semantically organizes a user's browsing history (with the help of the Delicious folksonomy) and enables him to quickly recall information distributed over several documents and/or sessions.  ...  Alice can navigate the map in order to revisit or reconstruct information distributed among several documents or sessions in the past.  ...

What Does a "Normal" Human Genome Look Like?

M. V. Olson
2011 Science  
Like the Constitution of the United States, the human genome turned out to be a sparse document, containing fewer genes than expected.  ...  In retrospect, this point leaps out as most signifi cant: 2001 marked the issuance of a founding document, a biological living constitution that remakes how we, as individuals and species, interpret our  ...  What Does a "Normal" Human Genome Look Like?

Nature's top 100 revisited

Lutz Bornmann
2015 Journal of the Association for Information Science and Technology  
This letter argues that such a list should not be produced on the base of bare citation counts, but normalized bibliometric indicatorsthe standard in bibliometrics.  ...  The search was restricted to articles and reviews; it is not clear which document types Van Noorden, et al. (2014) considered.  ...  The great difference between both lists underlines the necessity to use normalized indicatorsas it is the standard in professional bibliometrics.  ...
