Embedded Scientific Computing
Data-Driven Business and Open Science
Using OpenCPU for integrating scientific computing into the next generation of systems and applications.
Methods for scientific computing are traditionally implemented in specialised software packages such as R or STATA. However, many users and organisations wish to integrate statistical computing into third party software. Ans so, rather than working in a specialised statistical environment, methods to analyse and visualise data get incorporated into pipelines, web applications and big data infrastructures.
OpenCPU is a software system for embedded statistical computation and reproducible research. The server exposes a web API interfacing R, Latex and Pandoc. This API is used for example to integrate statistical functionality into systems, share and execute scripts or reports on centralized servers, and build R based “apps“.
OpenCPU app is an R package which includes some web page(s) that call the R functions in the package using the OpenCPU API thereby making a convenient way to develop, package and ship portable, standalone R web applications.
- focuses on domain specific challenges related to integrating scientific computing into the next generation of systems and application.

Automatic Recognition of Product Mentions in Text Corpora
Kaggle Competition
Identify product mentions within a largely user-generated web-based corpus and disambiguate the mentions against a large product catalog.
Challenge
- to automatically identify all mentions of consumer products in a largely user-generated collection of web content, and to correctly identify the product(s) that each product mention refers to from a large catalog of products.
- hundreds of thousands of text items, a product catalog with over fifteen million products, and hundreds of manually annotated product mentions supporting data-driven approaches.
- submission of disambiguated product mentions will be scored based on the mean F1 correctness metric.
- rules
Winners:
1st Zhanpeng Fang
- Solution documentation and interview: C, Python and Perl
- Paper: Accurate Product Name Recognition from User Generated Content
- Slide
2nd: Olexandr Topchylo
- documentation: C++
How to install the ‘RWordPress’ package in R
The RWordPress package is a very convenient tool for publishing blog posts from R to WordPress. In his blog post Publish blog posts from R + knitr to WordPress, Yihui Xie explains how to install and use the package. Furthermore, the blog post How to publish with R Markdown in WordPress gives some additional information on how to use the package.
However, the package repository http://www.omegahat.org/R does not seem to exist anymore (2016-04-04).
Fortunatelly, the RWordPress package is also available from Github and, thus, can be easily installed using the devtools package.
Since RWordPress depends on the packages RCurl, XML, and XMLRPC, these packages need to be installed before we can actually install RWordPress.
Unlike RCurl and XML, the XMLRPC package is not available from the CRAN repository. Instead, it is available from Github.
Here is the code to install all required packages:

Comparing Water and Social Data Quality
Introduction
Quality is the standard of something as measured against other things of a similar kind; the degree of excellence of something.
Pollution is the presence/introduction of a substance which has harmful or poisonous effects in an environment. Pollution can loosely be defined as the deterioration of an existing state.
Water Pollution
Understanding the source of pollution is necessary for eliminating, minimising, reusing or treating their negative effect on the environment.
Classification of the sources of water pollution (Water Quality control Handbook)
Water Quality
Maintaining high water quality or keeping water systems safe is a continuous real-world challenge.
The key to a successful water quality system in today’s environment is using established parameters to measure change over time at varying locations in the network on a continuous basis. These measurement parameters include pH, conductivity, free chloride, monochloramine, dissolved oxygen, ammonium, turbidity, fluoride, ozone, temperature. Read more…

Learning in Higher Education
My Philosophy of Teaching
I have been teaching or supporting learning in higher education since 2010, my perception about teaching in higher education is basically to ensure the coverage of the syllabus of each module within a given time frame and to measure students understanding through formative assessment. The greatest shift in that perception came when I enrolled in Learning & Teaching in Higher Education module in 2015 . While studying some occasional papers, relevant/recommended texts and attempting the module activities, I came across the following tough questions in :
- Why do I teach?
- What do I believe or value about teaching and student learning?
- How do my research and disciplinary context influence my teaching?
- How do I address the challenges and resources of teaching in my particular discipline?
- How do my identity/background and my students’ identities/backgrounds affect teaching and learning in my classes?
- How do I utilise multiple pedagogical approaches in my teaching?
- What is my approach to evaluating and assessing students?
Answering these questions will reveal one’s strategies for promoting productive engagement with learning.
