Background: Syrian activists, Arab and international human rights organizations and journalists
have been collecting information to document crimes committed by the Syrian security forces
against Syrian citizens. YouTube videos, reports by Non-Governmental Organizations (NGO),
demanded of the United Nations (UN), interview transcripts, and news reports: all such sources
of information exist independently, left unorganized and thus unable to make an optimal impact
on advocacy for an international response to the crisis in Syria. This website, Syria Tracker, was
developed to leverage information that is produced by citizen reporters and in collaboration with
a variety of entities and made publicly available in disparate locations to produce a free
centralized source of information. Hereinafter, we refer to this method of harnessing labor and
information contributed by a large group of people as opposed to an employee or an expert
contractor as crowdsourcing.
Ushahidi: The near-ubiquity of cell phones worldwide and enhanced access to the Internet over
the past few years indicates that the world can hear about and respond to reports of events
taking place, even inside repressive regimes. This activity and reactivity may occur in near real-
time. Individuals around the world can access volumes of data made easily digestible to a
diverse audience through live maps and other visualization techniques. Ushahidi, a small, non-
profit technology company based in Kenya provides free and open source software as a
platform through which one can leverage crowdsourced reports to generate live maps. At the
bleeding edge of new practices deploying live maps in conflict and crisis situations, Ushahidi
first launched its platform in 2008, which was used (in combination with Short Message Service
(SMS)) to document rising human rights violations and post-election violence in Kenya. In
2010, Ushahidi released Crowdmap, a public implementation of the Ushahidi platform hosted in
the Internet cloud. Anyone can construct a basic Crowdmap within minutes, centered upon the
location and extent of one’s choice, and generated with relevant, user-defined categories that
best fit the context. Subsequently, interested users around the world have generated thousands
of individual Crowdmaps tracking events or relief needed; such as tracking: oil spills, election
intimidation, corruption, tornados, power outages, civil wars, and food and water requests after
an earthquake.
2. The web-based Crowdmap allows users to crowdsource information from multiple channels,
such as email, Twitter, YouTube videos, online news, syndicated feeds (such as Really Simple
Syndication (or RSS)), webform, or mobile apps, among others. The Standby Task Force
(SBTF) (http://blog.standbytaskforce.com), an online volunteer community established at the
second annual International Conference on Crisis Mapping (ICCM)
(http://www.CrisisMappers.net) in October, 2010, was activated in April 2011 for 2 weeks to help
Syria Tracker cope with the initial surge of crisis events from Syria.
Methodology: Using Ushahidi’s Crowdmap product, we developed Syria Tracker [See Figure 1:
http://syriatracker.crowdmap.com] to be a crowdsourced effort where citizen reporters on the
ground or abroad are reporting crimes in Syria either via direct web entry [See Figure 2], by
sending reports via email to syriatracker@gmail.com, by tagging their tweets with
#basharcrimes, or by leaving a voice message to US-based number “+1 931 682 6708”.
Additionally, at the beginning of the effort Syria Tracker adopted a Speak2Tweet service
(http://twitter.com/speak2tweet) that was developed by Google in light of the January 25 events
in Egypt. The service accepted voice messages from Syria to either “+16 50 4194 196” or “+39
06 62207 294” or “+44 20 3318 4514” and automatically posted the recorded messages to
twitter with hashtag #Syria.
Syria Tracker also incorporates complementary situation awareness information (news, blogs,
Facebook posts, etc.) from the HealthMap system [1-3], hereinafter referred to as “HealthMap
Crisis”. HealthMap is an information system that tracks disease outbreaks using unofficial
reports (e.g., informal interviews of clinicians, web-based health-related articles by news media,
amateur blogs). HealthMap Crisis was tailored to mine information in English for evidence of
crises (e.g., killing, torture, detainment). HealthMap Crisis is provided as a news stream that is
available to the public on the Syria Tracker’s website. Syria Tracker is collaborating with the
following crowdsourced efforts to further validate and disseminate the information: Middle East
Voices (Voice of America http://middleeastvoices.com/map-of-deaths-in-syrian-uprising-beta),
Syrian Martyrs اﻟﺳورﯾﺔ اﻟﺛورة ﺷﮭداء (http://syrianshuhada.com), Silmya (http://silmya.org), and Syrian
Youth Movement (http://mar15.info).

Syria Tracker provides a “voting” capability for eyewitness reports so that any ones with low
confidence levels can be identified by the community. Names of victims have been collected as
frequently as possible to reduce the chance of duplicate reports and to support the UN Human
Rights Council recommendations for documenting the crimes for future investigation.
Results: Syria Tracker was launched on April 23, 2011 and, as of January 9, 2012, has been
able to log aggregate or individual reports since March 18, 2011, including 550 reports for the
category “Killed (لِﺗُﻗ)” and 356 reports for the category “Missing-ﻣﻔﻘود or Detained-ﻌﺗﻘلُﻣ”. A total of
6,317 individuals killed [See Figure 3] over 286 days (March 18, 2011 thru January 8, 2012)
were documented and verified. Killing ranged from 1-210 killings per day (median of 17.5 (95%
CI:14-19)), in 463 cities [See Table 1], affecting all age groups (median age of 36 years old
(95% CI: 27-45)) with 427 individuals (~7%) less than or equal to 18 years old [See Figure 4],
and 289 individuals were female (~5%) and 6,028 were male (~95%).
Depending on the levels of violence in Syria, the typical amount of time for an eyewitness report
is 1-3 days, and aggregate reports are developed once a week. More than 88% of the current
6,317 entries in the Syria Tracker database through Jan 9, 2012 have names associated with
them, although in some of the more violent periods counts were located to sub-portions of the
city and dates to reduce the chance of duplicate reports.
Change Point Analysis (or CPA) [4] identified the following significant changes in the time series
[See Figure 3]: 74 individuals killed on 4/8/2011, 57 individuals killed on April 22, 2011, 162
individuals killed on April 29, 2011, 65 individuals killed on May 1, 2011, 33 individuals killed on
June 2, 2011,86 individuals killed on June 3, 2011, 56 individuals killed on 6/5/2011, 210
individuals killed on 6/10/2011, 140 individuals killed on July 31, 2011, 144 individuals killed on
5. August 7, 2011, 74 individuals killed on October 28, 2011, 122 individuals killed on December
19, 2011, and 146 individuals killed on December 20, 2011. As of January 8, 2012, a total of
407 killings have been documented since the Arab League observers began arriving in Syria on
December 26, 2011 to check on implementation of an Arab peace plan.

10. As of December 12, 2011, Syria Tracker had received visits from 1,071 cities (with the top three
being: Damascus Syria, Washington DC, and Riyadh Saudi Arabia) in 114 countries (~91% of
the visits from Syria were new visits). Approximately, 30% of the traffic to Syria Tracker was
indirect. For example, search engine results link to Syria Tracker for inquiries into specific
events or searches for loved ones that are missing or killed; and, ~65% direct or referral traffic
from other news outlets, social networking sites, or humanitarian websites (Voice of America,
Amnesty International, Major News Agencies, etc).
HealthMap endeavored to draw information from the widest range of media sources [See Table
3 and Figure 5] possible to reduce any potential reporting biases from news media with certain
political slants. From June 13, 2011, when HealthMap began providing meaningful data for
Syria Tracker, to January 8, 2012, over 43,000 news and blog articles were collected, drawing
from almost 2,000 unique sources writing in English across the globe. More than half of the
sources contributed four or more reports to the database [See Figure 5]. Sky News, Press TV
and the Syrian Arab News Agency (SANA) were excluded from data collection from June 30,
2011, though other pro-regime news sources remained.

Conclusion
Since April 23, 2011, the Syria Tracker (http://syriatracker.crowdmap.com) crowdsourcing
application has been collecting citizen reports of crimes against humanity as part of the Syrian
protests for reform. Supplementing these reports with multiple sources for verification, Syria
Tracker consolidates these eyewitness reports with, advanced mining and aggregation of
English news feeds, statistical reports and visualizations in Arabic and English. But Syria
Tracker’s ultimate goal is not to provide numbers, but to preserve the name, and the location of
each victim in this unfolding tragedy so that they will not have died in vain. Whenever possible,
each death is also linked with photo and video evidence which, although it may be graphic and
disturbing, does support the recommendations of the UN Human Rights Council to create a
documented record so that these crimes will not be forgotten.
A single place to pull disparate reports on human rights violations together in a crowdsourced
way is crucial to make sense of the broader pattern of abuse and demonstrate a widespread
and systematic attack on civilians, the legal qualification of crimes against humanity. Syria
Tracker documented and mapped thousands of reports. We hope these documentations serve
as an evidence on where harm was inflicted upon citizens in Syria. This is important in order to
change the nature of advocacy around the plight of the Syrian people – and not only advocacy,
15. but also long-term thinking about a post-Assad Administration transitional justice and shorter-
term thinking about accountability for the most senior members of the regime.
