3. KEY PROBLEMS WE ARE WORKING ON
Traffic & Mapping
Local Search for businesses, events, points of interest
Lifestyle content & recommendation engine
Combination of “traditional” big data processing, machine
learning and proprietary algorithms
People are drowning in information
– use “big data” signals to condense to something manageable
4. TRAFFIC & MAPS
Traffic-aware routing engine
– Navigation is core competency
– 1.3B routes/trips since 2007
Routes generate traffic/motion data
– “probe data” from app (billions/month)
– Anonymized & summarized to power routing
– Persisted in aggregate form for historical
traffic metrics
Used to augment Open Street Map
– Turn restrictions, stop signs, road geometry
– Deduced from probe patterns
Technology set
– Hadoop + Hive
5. AUTOMATED DEVELOPMENT OF RICH LOCAL CONTENT
(YOU MAY KNOW THIS AS GOBY)
Categorized to
taxonomy (“blues”,
“hiking trails”)
all entities geotagged
OTHER FEATURES WORTH NOTING
• automatic entity/place creation
• aggregated ratings & reviews
• proprietary result ranking formula
venues automatically
recognized; events • domain-specific metadata extraction
mapped to venues • sorting by metadata (e.g. price, rating)
6. AUTOMATED DEVELOPMENT OF RICH LOCAL DATA
Data space is large, but not immense
– Tens or Hundreds of millions (or smaller), not billions
But very complex
– Thousands of data sources
– attribute space is 10,000 wide
– E.g. how many holes in the golf course; how long is the hiking
trail?
Generates a large, sparse matrix
– Ambiguous, conflicting data
– Unstructured or semi-structured data
– Need to recognize entities & merge/dedup
10. RECOMMENDATIONS – WORK IN PROGRESS
Key signals
– Personalized “interest graph”
– “Drive to” data (where are people driving to?)
– Entity-level “page rank”
– Web/mobile clickstream data
Integrated with social media
– Facebook actions influencing recommendations
Key technology enablers
– Large amounts of user-generated data
– Proprietary algorithms; machine learning / SVM
