SAS Visual Text Analytics provides dictionary-based and non-domain-specific tokenization functionality for Chinese documents, however sometimes you still want to get N-gram tokens. This can be especially helpful when the documents are domain-specific and most of the tokens are not included into the SAS-provided Chinese dictionary. What is an N-gram? An
Gradient boosting is one of the most widely used machine learning models in practice. See how to use gradient boosting model for classification in SAS Visual Data Mining and Machine Learning.
Report data shared by educational institutions, government agencies, healthcare organizations, and human resource departments can contain sensitive or confidential data. Data in such reports are suppressed selectively to protect the identities of individuals or to prevent the report’s audience from easily inferring individual values. The Data Suppression feature in SAS
Jazz up your Geo Map or Network Analysis graph by applying icon-based display rule markers instead of color markers on the map. With SAS Visual Analytics, you may have already used display rules by populating intervals or adding color-mapped values for report objects. Now, you can jazz up your Geo
Every year in early October, the eyes of the world turn to Sweden and Norway, where the Nobel Prize winners are announced to the world. The Nobel Prize is considered the world's most prestigious award. Since 1901, the Prize has been presented to individuals and organizations that have made significant
The Dw.p format displays numeric values, in a field w positions wide, possibly with a great range of values, lining up decimals for values of similar magnitude. The BESTDw.pformat combines the BESTw. format for integers and the Dw.p format for nonintegers. Specifying BESTDw.p (where p = w - 1) is better than specifying BESTw. for columns, since decimals do not shift when the last digit is 0.
SAS Visual Analytics 7.4 comes chock-full of new features. Report and section linking come with an added benefit. If you set up linking from one section to another section in the same report, or from one report to another report, you have the option to configure linking such that any filter
In addition to his day job as Chief Technology Officer at SAS, Oliver Schabenberger is a committed lifelong learner.

Community detection has been used in multiple fields, such as social networks, biological networks, tele-communication networks and fraud/terrorist detection etc. Traditionally, it is performed on an entity link graph in which the vertices represent the entities and the edges indicate links between pairs of entities, and its target is to
In 2011, Loughran and McDonald applied a general sentiment word list to accounting and finance topics, and this led to a high rate of misclassification. They found that about three-fourths of the negative words in the Harvard IV TagNeg dictionary of negative words are typically not negative in a financial
As a practitioner of visual analytics, I read the featured blog of ‘Visualizations: Comparing Tableau, SPSS, R, Excel, Matlab, JS, Python, SAS’ last year with great interest. In the post, the blogger Tim Matteson asked the readers to guess which software was used to create his 18 graphs. My buddy,
Recently a colleague told me Google had published new, interesting data sets at BigQuery. I found a lot of Reddit data as well, so I quickly tried running BigQuery with these text data to see what I could produce. After getting some pretty interesting results, I wanted to see if
In my last post, I showed you how to generate a word cloud of pdf collections. Word clouds show you which terms are mentioned by your documents and the frequency with which they occur in the documents. However, word clouds cannot lay out words from a semantic or linguistic perspective.
Last week, I attended the IALP 2016 conference (20th International Conference on Asian Language Processing) in Taiwan. After the conference, each presenter received a u-disk with all accepted papers in PDF format. So when I got back to Beijing, I began going through the papers to extend my learning. Usually, when
Tablets, phablets, smartphones. These mobile devices not only travel to different corners of the earth with their owners; they participate in certain adventures that can result in an unexpected turn of events. Thanks to their mobility, these devices can be misplaced. And they could be found later. In rare cases,
Mobile devices travel with humans pretty much anywhere that humans want to go. Unlike desktop computers that stay fixed and grounded within brick and mortar walls, mobile devices are used in all sorts of locales – offices, homes, cars, planes, swimming pools, soccer fields, movie theaters – the list goes
