{multi-excerpt:name=UseofBrowsers}The next several sections analyze available statistics for direct use of EVS resources on EVS servers. This section covers direct use of NCI-hosted EVS terminology browsers and the LexEVS local java API that supports them. Later sections cover the LexEVS distributed (remote), LexEVS caGrid services, the term suggestion site, and ftp download services.
{toc:minLevel=2}
The EVS browsers and LexEVS APIs at NCI are covered by the AWStats and Wusage applications, recording various statistics including number of unique visitors, visits, number of pages viewed and data volume accessed. These have been collected below to give a window into the use of the EVS services. Appendix 1 lists the usage tracking pages from which these statistics are gathered.
We are now able to identify and exclude most web crawler and similar automated hits, as well as internal use for testing and development purposes. Detailed examination of addresses and patterns of use suggest that the use reported below overwhelmingly represents real users from NCI and other organizations of interest. Analyzed below are figures for unique visitors and number of visits, as well as the volume of data communicated, which for all but ftp sites reflects high volumes of traffic in mostly compact units of terminology concept data.
h2. Statistical Overview
The EVS browsers run off the LexEVS local API, and provide the highest number of direct users of EVS terminology servers. The lowest, but most informative, numbers are for unique visitors and number of visits. The number of unique visitors to the EVS family of browsers has averaged around 3,000 per month over the past year, generating a total of around 6,000 visits per month.

h2. Browser Users
The data below is from January 2013 through July 2013. It shows an overall view of which domains hit EVS browsers most heavily, and then breaks down each domain by top users. All browsers are put together for this analysis.
h3. Overall Use
The amount of bandwidth used was divided into four (4) major groups: Government .gov users, private .com and .net users, Educational .edu institutions, and Organizations .org. The data was analyzed and bots were discarded to avoid skewing the data.

The numbers below show the top government users of the EVS browsers, as measured by the MB of data that were accessed. Agency names have been provided where they are known. The main users are internal to NCI and NIH, which is not surprising, but we have significant usage from FDA.

We combined the .net and .com users into one group as both contained a number of private corporations and individual users from a wide variety of ISPs (collectively labeled as ISP). Business names have been provided where known. The graph below does not fully show ISPs they dwarf the next largest groups.

Nearly 75% of all use goes to the NCIt browser, including almost all use from the educational domain and two thirds of government use. By contrast, half of commercial domain use goes to NCI Terms, while .org use is almost evenly split between all three browsers.
