 jleyva in  Métricas Web continues his series on web metrics with a summary of the metric: web page search and retrieval.

Web page search and retrieval metrics measure and compare the processes of sending and retrieving of information. There are two categories:

• Effectiveness. The efficiency of recovery of information from the web is measured with two metrics: precision and recall. Precision is the proportion of pages returned which are relevant for the search and recall measures the grade of the relevant pages returned from the search.
• Search engine comparison. In order to compare the quality of different search engines, there are some key metrics:
• • Coverage. This measures the number of results returned by each engine.
  • Relevance. One metric is the proportion of interesting results returned by a search engine across a number of terms. A second metric is the proportion of results returned from different search engines with respect to a specific term.
  • Performance. This is the time taken to perform the search and return the results to the user.

rfog in  Diario de un Programador speculates on the support by Borland of the C++ language in its  Borland C++ 2005.
