1. UI/UX can be improved by applying ambient location information

The Brooklyn Problem


Brooklyn, New York Brooklyn, Alabama

The Brooklyn Problem


if ($query == ‘Brooklyn’) {return ‘Brooklyn, NY’;}


Solr 3.10, Maxmind world populations dataset, bash, and an “algorithm”


<fieldType name="location" class="solr.LatLonType" subFieldSuffix="_coordinate"/>

....

<field name="latlong" type="location" indexed="true" stored="true" required="true" />

schema.xml:

Solr geo-spatial extension 3.10+


<?php

$fh = fopen('worldcitiespop.txt', 'r'); $row = fgetcsv($fh); // discard headers for($i=0;$i<100;$i++) { $row = fgetcsv($fh); $json = array('add'=> array('doc' => array( 'terms' => $row[2] . ' ' . $row[0], // city country 'population' => $row[4], 'latlong' => $row[5] . ',' . $row[6], // "latitude,longitude" gets parsed ))); curl_post(json_encode($json)); } } function curl_post($json, $url='http://localhost:8983/solr/update/json') { $ch = curl_init(); curl_setopt($ch, CURLOPT_HTTPHEADERS, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_URL, $URL); }?>

ALL THE CODE!


http://localhost:8983/solr/update/json'

http://localhost:8983/solr/update/json'

“a custom Solr scoring function to re-rank results based on social geo-relevance”


div(geodist(),sqrt(sum(population,1))


http://localhost:8393/solr/placesuggest/select?q=b*&sfield=latlong&pt=37.7749295,-122.4194155&sort=div(geodist(),sqrt(sum(population,1)))%20asc













OMG CONTEXT SENSITIVE PERSONALIZED

GEOCODING!!!!!































































































Done!


* Solr 3.10+ working geo-spatial extensions* 2.6 million points == 380Mb index* the data sucks, and it doesn’t matter (much)* a few days of work, 85% increase in data quality.

the tear down


.Wanjialing, China


Brooklyn NY, population: 0


So why aren’t people doing this?
