Google APPs and Google APIs

1. Google APIs By Mohammed Farrag Shibin Al-Kawm GTUG Admin

2. What is API ?! About Google API. Start Using Google API. Google API in different languages. Manage your business using Google API. How Google builds API ?! Future of Google API. Google API Code Explorer. Google API Periodic Table. Google Competitions. Be Googler !! Overview

3. Google API

4. Allows search over Google’s entire index of billions of web pages. Enabling developers to give customers more information with the interactivity consumers and business users expect. Uses SOAP - Simple Object Access Protocol – used for information exchange (esp. http). Google APIs

5. • But: – Limit of 1,000 queries per day (without special arrangement). – Limit of 10 results per query (top 10) • Can be overcome somewhat through query refinement).

6. • Register http://code.google.com/intl/ar/apis/base/signup.html • Agree to terms and conditions • Get key – A 32 byte code – Needed for each query submission – E-mailed to you • Download API Getting Started

7. Google Java API • API for Java is an executable jar • Set appropriate classpath • Some sample code: import com.google.soap.search.*; … GoogleSearchgoogs = new GoogleSearch(); googs.setKey(myGoogleKey); googs.setQueryString(“TREC 2005 papers"); GoogleSearchResultgoogResults = googs.doSearch(); GoogleSearchResultelementr.getResultElements(); max = googResults.getEstimatedTotalResultsCount(); GoogleSearchResultElementmyresults[] = googResults.getResultElements(); String a_URL = (String) myresults[1].getURL(); Google Java API

8. So How do I Query Google? #!/usr/local/bin/perl –w use SOAP::Lite; # Configuration $key = "Your Key Goes Here"; # Initialize with local SOAP::Lite file $service = SOAP::Lite -> service('file:GoogleSearch.wsdl'); $query= “duluth”;

9. Search Contd… $result = $service -> doGoogleSearch( $key, # key $query, # search query 0, # start results 10, # max results "false", # filter: boolean "", # restrict (string) "false", # safeSearch: boolean "", # lr "", # ie "" # oe );

10. Limit is 1,000 queries – Catch GoogleSearchFault, or, – Local counter to track – In any case, put thread to sleep for 24 hrs. • Google server may get overloaded – In error processing, capture “Please try again in 30 seconds” – Put in 30 second sleep, and retry query Programming Notes

11. getEstimatedTotalResultsCount max = googResults.getestimatedTotalresultsCount(); – max could be more than 10 – max is an estimate; could be wrong • Search only over main index (no GoogleScholar, Froogle, etc..).

12. Geo-Google

13. The world is 3D! Users implicitly understand 3D from... the real world! Very effective in communicating geospatial information. Google Geo APIs
