The ratings are calculated by counting hits of the most popular search engines. The search query that is used is¿Son importantes estos índices? La popularidad implica que han ocupado la atención pública, que fue analizado para su adopción, que distintas comunidades recurrieron a consultas para resolver problemas o educarse, en fin, que estuvieron en el foco de la atención de la comunidad de la industria. Pero no habla en todo caso de los consolidados, aquellos que se usan sin ruido, y que pueden ser usados también en abundancia, como sin duda sucede con COBOL, RPG y otros.
+"This search query is executed for the top 6 websites of Alexa that meet the following conditions:programming"
Based on these criteria currently Google (32%), YouTube (10%), Yahoo! (3%), Bing (3%), Wikipedia (16%), Blogger (32%) and Baidu (3%) are used as search engines. The number of hits determine the ratings of a language. The counted hits are normalized for each search engine for the first 50 languages. In other words, the first 50 languages together have a score of 100%. Let's define "hits50(SE)" as the sum of the number of hits for the first 50 languages for search engine SE and "hits(PL,SE)" as the number of hits for programming language PL for search engine SE. Possible false positives for a query are already filtered out in the definition of "hits(PL,SE)". This is done by using a manually determined confidence factor per query. A query such as "Basic programming" also returns pages that contain "Improve your basic programming skills in Java". The first 100 pages per search engine are checked for possible false positives and this is used to define the confidence factor. If this factor is 90%, then only 90% of the hits are used for "hits(PL,SE)". An overview of the confidence factor can be found in the groupings table below.
- The entry page of the site contains a search facility
- The result of querying the site contains an indication of the number of page hits
The ratings are calculated with the following formula:
((hits(PL,SE1)/hits50(SE1) + ... + hits(PL,SEn)/hits50(SEn))/nwhere n is the number of search engines used.
En el último tiempo, suele hablarse de Java como un lenguaje "corporativo", igualándolo a "legacy". Su continuidad en la primera línea en todo caso muestra que su interés no se ha amortiguado.
