How they work


CheAuto, Quattroruote's online service helps customers find
used cars and:
quickly sorts through over 350,000 ads from the main sites
of used car listings
is different from traditional search engines because it allows
users to make their requests in everyday language; an
example search could be, “I'm looking for a 2008 Passat,
red, 6-speed in Chicago”

Search methods are simple and fast
Results are timely and accurate


automatically interprets the requests: only through semantics
is it possible to understand that “I'm looking for a 2000 Alfa
147” is different from “I'm looking for an Alfa 147 2000”
because in the first case 2000 indicates the model year and
the second case indicates engine volume

Users had to explore many different
websites in order to find the ads that
interested them and then had to
compare each of them separately

extracts the most relevant text entities from the user's
request and filters only the pertinent results; at any time,
the user can also select additional search criteria (make,
model, price, region, etc...) from simple drop-down menus

Prices were manually compared to
Quattroruote's suggested retail

compares the prices listed in each sales ad with
Quattroruote's suggested retail values and displays a graphical
assessment (red light for high asking prices, green light for
low asking prices and yellow light for reasonable asking

Traditional search engines function
only by keyword

With a single search engine, results
are obtained from multiple sources
and are more accurate
The engine allows users to make
requests using everyday language
Price comparisons are provided
