Use cases

BNOSAC is specialised in predictive data mining on huge databases to aid in better decision making. We adopt the newest statistical and technological innovations and apply it for business purposes. Our methodology is proven to be excellent by obtaining the second place at the Florida data mining competition.

activities standard data miningWe focus on the following domains:

  • Text analytics on emails
  • Typical use cases are: Understanding issues, IT handling reduction time, Automated replies matching FAQ lists, Integrating into predictive models (churn / upsell), Better email redirections (process efficiency) & Automatic solving of client issues

Production & quality control

  • Models to identify causes of system breakdown
  • Predict productivity by using time series models
  • Statistical evaluation and optimisation of quality of product items
  • Improve by using fuzzy measurement technologies
  • Link quality to customer satisfaction and develop risk frameworks

Automation & integration
  • We set up data marts for data mining purposes, automate the modelling + scoring and create easy to use interfaces.

 

R methodology

logo r  BNOSAC provides expertise in statistical modelling, data science, text mining, web scraping, biostatistics, statistical web development and integration services regarding data analytics. R is always a component which is included into these services as it is the most used data science software worldwide. 

R inside the organisation + R architectural advice

We provide R support which is detailed here. If your team uses R, there are different levels of maturity which require different skillsets in the organisation.

BNOSAC sets your team on the right track regarding R usage by providing in-house courses as well by sharing best practices for R usage for each application domain and each business. We also provide architectural advise on the usage of R. Contact us for more details by filling the web form.

R project set up by BNOSAC 

1 As a standard delivery, projects with an R component by BNOSAC consist of the following elements:

  • One or several R packages which were developed to execute the analysis and for reproducibility
  • A CRAN-like R package repository which can be used to install all the packages and the dependencies
  • Access to the RolleR R continuous integration environment by BNOSAC.
  • In-house training for R users for based on the training courses listed here. This includes making sure you can redo the analysis in-house and have in-depth understanding of the techniques used.

r deployment

2 All R packages are delivered according to the current standards, namely:

  • By using the development environment RStudio
  • All functions are put into an R package and are documented with roxygen code blocks, based on which documentation is provided. These contain examples based on data delivered by the client which is included inside the package
  • The R package contains a vignette with general overview documentation how to use the function
  • For core functionality, unit testing are specified
  • All code passes R CMD check, so that it can be published on CRAN
  • The client specifies the licence and is owner of the code if specified during the setup

3 During the initial meeting, we discuss the setup and the backbone of the application which can for example be as follows

Spatial Analytics

At BNOSAC, we use spatial data mining to discover interesting and previously unknown spatial patterns in large datasets. The service line spatial data mining executes exploratory spatial analysis, we create Web Map Services(WMS), perform geomarketing analytics, do analysis of recorded GPS log trackings, create custom based interactive maps, provide data enrichments or perform advanced geostatistics.

Business Mapping and geostatistics

If you are interested in simple mapping of geostatistical data in order to know the best potential of new sites, to optimally leverage your promotions or to see how your customers behave on a certain campaign in your area of interest, we can help you. We make geomarketing maps of your data tailored to your needs. Our mapping tools allow you to visually see where you can boost your sales with a minimal marketing effort.

  Geocoding

Geocoding refers to adding lattitude and longitude coordinates to addresses of customers in your database so that they can be plotted. BNOSAC offers gecoding services freely if other analytical services are included in the contract. Mail us so that we can contact you to supply you with more detailed information.

  Open Data about Belgium

BNOSAC provides open data about Belgium in any suitable format. A number of open source R packages for this are made available at https://github.com/bnosac/BelgiumMaps.StatBel and at https://github.com/weRbelgium.

If you want more detailed information about the possible data which can be provided for your business, mail us so that we can contact you to supply you with more detailed information.

Data Enrichments & Web Map Services

Having latitude/longitude pairs or data from OpenStreetmap is just the beginning of your spatial journey. You are probably interested in other elements like what part of the country do our branches cover, who is living there and what do they do. We set up new data enrichments and maps and provide you the shape files. So that these mapping solutions can be included at your intra- or internet for a wider audience. We help you set up these web map services and provide analytical geostatistics & data manipulation. Contact us if you want to discuss the requirements of your project.

GPS log analysis

Do you want to know where your customers live, how they move, which places interest them and what they do there and you want to know how you can target them better and more efficiently, we are there to help. We analyse GPS logs and set up predictive models to improve customer experiences.

Training

We give training in spatial analytics using open source tools. This training covers the following topics.

  • Importing spatial data and setting the spatial projection
  • Plotting spatial data on static and interactive maps
  • Adding graphical components to spatial maps
