Welcome to EICS 2016
[Extract] The ACM SIGCHI Symposium on Engineering Interactive Computing Systems (EICS) is
a yearly international conference devoted to engineering usable and reliable
interactive computing systems. Research presented at EICS revolves around methods,
processes, techniques and tools that support specifying, designing, developing,
deploying and verifying interactive systems. This 8th ACM SIGCHI Symposium on
Engineering Interactive Computing Systems (EICS'16) took place in Brussels, Belgium
(21-24 June 2016) – at the heart of Europe...info:eu-repo/semantics/publishedVersio
Clustering Arabic Tweets for Sentiment Analysis
The focus of this study is to evaluate the impact of linguistic preprocessing and similarity functions for clustering Arabic Twitter tweets. The experiments apply an optimized version of the standard K-Means algorithm to assign tweets into positive and negative categories. The results show that root-based stemming has a significant advantage over light stemming in all settings. The Averaged Kullback-Leibler Divergence similarity function clearly outperforms the Cosine, Pearson Correlation, Jaccard Coefficient and Euclidean functions. The combination of the Averaged Kullback-Leibler Divergence and root-based stemming achieved the highest purity of 0.764 while the second-best purity was 0.719. These results are of importance as it is contrary to normal-sized documents where, in many information retrieval applications, light stemming performs better than root-based stemming and the Cosine function is commonly used

The Anchor, Volume 118.11: November 17, 2004
The Anchor began in 1887 and was first issued weekly in 1914. Covering national and campus news alike, Hope College’s student-run newspaper has grown over the years to encompass over two-dozen editors, reporters, and staff. For much of The Anchor\u27s history, the latest issue was distributed across campus each Wednesday throughout the academic school year (with few exceptions). As of Fall 2019 The Anchor has moved to monthly print issues and a more frequently updated website. Occasionally, the volume and/or issue numbering is irregular
