Mayaro Virus (MAYV) Miner


, , , , ,

This is a new miner that is available now at

Research the scientific literature for the Mayaro Virus (MAYV). Read research and news from CDC, NIH, WHO, and other sources. Search by location, site, or health organization. Recrawl search results to build your own curated collection on MAYV.

This is a new disease with symptoms similar to Chickungunya (CHIKV) but stronger. It is now moving to the Caribbean and soon to PR and Florida.


Probabilistic Model Tutorial


, , ,

This is an updated version of a tutorial on the Robertson-Spärck-Jones Probabilistic Model.

It is available now at

The model computes global weights, known as RSJ weights, based on Independence Assumptions and Ordering Principles for probable relevance. The model subsumes IDF and IDFP as RSJ weights in the absence of relevance information.

Enjoy it.

09-26-2016 Update: A new section was added to the tutorial before the Conclusion section. References were added accordingly. Few lines were edited.

PS: I corrected the original publication date to read “Published: 03-30-2009” which is the correct date. My fault.

Moving Averages Calculator


, , , ,

Calculate several moving averages, including simple, cumulative, and exponential moving averages with this new tool, available at

A great tool for researchers, teachers, and students! Just enter a data set and the range to be shifted.

72 Binary Similarity Measures


, , , , , , , , , , , , , , , , ,

We have expanded the number of similarity measures that our Binary Similarity Calculator computes from 30 to 72 (and counting…)

Same measures with different names have been consolidated into a single record, and different measures with same name have been enumerated as necessary.

These similarity coefficients have many applications across disciplines: from bioinformatics to chemistry, chemometrics, statistics, data mining, information retrieval, marketing research, etc.

The tool is available at

We have also included the new similarity measures proposed by Consonni & Todeschini (2012), and Todeschini, et al (2012).

Our Tutorial on Distance and Similarity was also updated, accordingly. Check it out at

USA City Distances Calculator


, , , , , ,

Calculate mile distances from one USA city to over 300 major cities with this O2M-powered calculator. The tool is available at

Use it to find all possible city-distance combinations at once. No need to mess over and over with annoying pull-down menus.

The distances computed are not driving distances, but based on geolocation data (latitudes and longitudes) as listed in Wikipedia at

The results are sorted alphabetically by city, states. The data is processed with our One-to-Many algorithm to showcase the many possibilities of O2M-driven tools. Additional O2M tools can be found at

Improving MUST


, , , , ,

We have tweaked MUST (Minerazzi URL Scoring Tool) to run a bit faster.

Try it with modern socials like

or with all those Old Glory Days URLs from the Search Engines Golden Age (the 90s). Check if they are defunct, redirecting, or still active.

AAAHHH: All those old days with their dumb business models.🙂
