base on A wikipedia search engine that is completely built in Java and works on Wikipedia XML dumps WikiSe : Wikipedia Search Engine ==================================== Arpit Bhayani A wikipedia search engine built using: - Java - XML Parsing using SAX Parser. - Ranking Algorithms It works on Wikipedia XML dumps.<br/> XML Dump Name : enwiki-latest-pages-articles.xml.bz2<br/> XML Dump Link : http://dumps.wikimedia.org/enwiki/latest/enwiki-latest-pages-articles.xml.bz2<br/> Implementation basic:<br/> High level of indexing which reduces the search time.<br/> The index terms are hashed to characters 'a' - 'z'<br/> Index is compressed at bitlevel. ( total size = 9.7GB )<br/> Special infobox parsing to provide direct answeres if possible.<br/> Special Features : 1. Index compression to make index half of its size. ( bit level compression ) 2. Special search fields provided so that user can directly search info infobox. e.g. Search Query : website:mumbai Title : mumbai<br/> Title : mumbai indians<br/> Title : 2012-13 mumbai f.c. season<br/> Title : 2008 mumbai attacks<br/> Title : maharashtra<br/> Title : public transport in mumbai<br/> Title : attribution of the 2008 mumbai attacks<br/> Title : list of constituencies of maharashtra vidhan sabha<br/> Title : wikipedia:files for deletion/2010 april 13<br/> Title : list of colleges in mumbai<br/> ****** {{url|www.mcgm.gov.in}} ****** <------ Website link Interesting search : - pratieik - chudail - joey tribbiani - cartoon nick:phoebe buffay powers:batman age:dimple kapadia population:amravati location:takla lake portrayer:joey tribbiani series:joey tribbiani t:priyanka t:priyanka age:priyanka Statistics: On a mchine of configuration : Lenovo Z580 , 4 GB of RAM , 5400rpm hard-disk - For 100 MB of data - Size of index ( primary+secondary ) : 24.3 MB - Time to primary index : 9.031 sec - Time to secondary index : 1.041 sec - Time to search : 0.007 sec - For 46.7 GB of data Wiki XML Dump : - Size of index ( primary+secondary ) : 9.7 GB - Time to index : 2hr 28min (average) - Time to search : 0.251 sec (average on 100 searches) ", Assign "at most 3 tags" to the expected json: {"id":"9956","tags":[]} "only from the tags list I provide: [{"id":77,"name":"3d"},{"id":89,"name":"agent"},{"id":17,"name":"ai"},{"id":54,"name":"algorithm"},{"id":24,"name":"api"},{"id":44,"name":"authentication"},{"id":3,"name":"aws"},{"id":27,"name":"backend"},{"id":60,"name":"benchmark"},{"id":72,"name":"best-practices"},{"id":39,"name":"bitcoin"},{"id":37,"name":"blockchain"},{"id":1,"name":"blog"},{"id":45,"name":"bundler"},{"id":58,"name":"cache"},{"id":21,"name":"chat"},{"id":49,"name":"cicd"},{"id":4,"name":"cli"},{"id":64,"name":"cloud-native"},{"id":48,"name":"cms"},{"id":61,"name":"compiler"},{"id":68,"name":"containerization"},{"id":92,"name":"crm"},{"id":34,"name":"data"},{"id":47,"name":"database"},{"id":8,"name":"declarative-gui "},{"id":9,"name":"deploy-tool"},{"id":53,"name":"desktop-app"},{"id":6,"name":"dev-exp-lib"},{"id":59,"name":"dev-tool"},{"id":13,"name":"ecommerce"},{"id":26,"name":"editor"},{"id":66,"name":"emulator"},{"id":62,"name":"filesystem"},{"id":80,"name":"finance"},{"id":15,"name":"firmware"},{"id":73,"name":"for-fun"},{"id":2,"name":"framework"},{"id":11,"name":"frontend"},{"id":22,"name":"game"},{"id":81,"name":"game-engine "},{"id":23,"name":"graphql"},{"id":84,"name":"gui"},{"id":91,"name":"http"},{"id":5,"name":"http-client"},{"id":51,"name":"iac"},{"id":30,"name":"ide"},{"id":78,"name":"iot"},{"id":40,"name":"json"},{"id":83,"name":"julian"},{"id":38,"name":"k8s"},{"id":31,"name":"language"},{"id":10,"name":"learning-resource"},{"id":33,"name":"lib"},{"id":41,"name":"linter"},{"id":28,"name":"lms"},{"id":16,"name":"logging"},{"id":76,"name":"low-code"},{"id":90,"name":"message-queue"},{"id":42,"name":"mobile-app"},{"id":18,"name":"monitoring"},{"id":36,"name":"networking"},{"id":7,"name":"node-version"},{"id":55,"name":"nosql"},{"id":57,"name":"observability"},{"id":46,"name":"orm"},{"id":52,"name":"os"},{"id":14,"name":"parser"},{"id":74,"name":"react"},{"id":82,"name":"real-time"},{"id":56,"name":"robot"},{"id":65,"name":"runtime"},{"id":32,"name":"sdk"},{"id":71,"name":"search"},{"id":63,"name":"secrets"},{"id":25,"name":"security"},{"id":85,"name":"server"},{"id":86,"name":"serverless"},{"id":70,"name":"storage"},{"id":75,"name":"system-design"},{"id":79,"name":"terminal"},{"id":29,"name":"testing"},{"id":12,"name":"ui"},{"id":50,"name":"ux"},{"id":88,"name":"video"},{"id":20,"name":"web-app"},{"id":35,"name":"web-server"},{"id":43,"name":"webassembly"},{"id":69,"name":"workflow"},{"id":87,"name":"yaml"}]" returns me the "expected json"
