The Challenge
Glen Cathey | #Intelligence16

A company's
employees are its
greatest asset and
your people are your
product.
Sir Richard Branson,
Founder of Virgin Group

I am convinced that
nothing we do is more
important than hiring
and developing
people. At the end of
the day you bet on
people, not on
strategies.
- Lawrence Bossidy, former COO
GE, CEO AlliedSignal/Honeywell

Recruiting Industry - Died
peacefully in its sleep. Lived
a wondrous life, creating and
filling jobs, inspiring technology
and building incredible wealth
for many. A true trailblazer.
Recruiting Industry was
preceded in death by fax
machine, land line, yellow
and white pages, Rolodex, job
board, job posting and ATS.
Recruiting Industry is survived
by its loving spouse Digital
Marketing; children CRM, Social
Media, Employment Branding;
grandchildren TRM, talent
communities, virtual reality and
dynamic content. In lieu of
flowers please send donations
for digital marketing training to
recruiters everywhere.

Lou Adler - The Recruiting Industry is Facing an Existential Threat: http://bit.ly/1X2Jiht
A surplus of talent model
designed to weed out the
weak will not work when a
surplus of talent doesn't exist.
Depending on function and
demand, 80-90% of all
candidates are not looking to
change jobs. Regardless,
companies spend more time
trying to hire the other 10-20%
more efficiently.

Recruiters are often handling too many requisitions
preventing them from performing outbound recruiting

The value of human capital data is directly proportional to
the ability to quickly, easily and precisely retrieve people
who have a high probability of being the right match

If you do not know how to ask the right
question, you discover nothing.

• Very few people mention every skill, environment or technology
they have experience with
• There are many ways of expressing the same skills and experience
• Employers often don’t use the same job titles for the same job
functions
• Candidates don’t create their resumes thinking how you will search
for them
• Sometimes candidates and employers don’t even use correct
terminology

• Both Kinds

Impact of Semantic Search in
Recruitment
• Recruiters can learn from "white box" solutions
• Lessens need for recruiters to be search experts to
effectively leverage the ever-increasing volume of
human capital data
• Enables recruiters with heavy req loads to perform
outbound recruiting, leveraging the deep end of the
talent pool

"A search engine cannot reliably surmise the
user's intent from a single query."

Human–computer information retrieval (HCIR) is the study of
information retrieval techniques that bring human intelligence into
the search process by taking into account the human context, or
through a multi-step search process that provides the opportunity
for human feedback.
"HCIR aims to empower people to explore large-scale information
bases but demands that people also take responsibility for this
control by expending cognitive and physical energy." – Gary
Marchionini
