Efficient search engine measurements

Ziv Bar-Yossef, Maxim Gurevich
2007 Proceedings of the 16th international conference on World Wide Web - WWW '07  
We address the problem of externally measuring aggregate functions over documents indexed by search engines, like corpus size, index freshness, and density of duplicates in the corpus.  ...  Furthermore, building on an idea from [10], we discuss Rao-Blackwellization as a generic method for reducing variance in search engine estimators.  ...  We therefore use three measures of efficiency for search engine estimators: query cost, fetch cost, and function cost.  ...

Semantic Web Search Model for Information Retrieval of the Semantic Data [chapter]

Okkyung Choi, SeokHyun Yoon, Myeongeun Oh, Sangyong Han
2003 Lecture Notes in Computer Science  
In this paper, we propose the ontology-based semantic web search model to enhance efficiency and accuracy of information retrieval for unstructured and semi-structured documents.  ...  New evaluation model is also proposed to measure the similarity between documents with semantic information. It is implemented and compared with the existing web models.  ...  However the new measuring method applied in the semantic search model uses the RDF semantic metadata to draw more efficient search results.  ...

Evaluation of Query Generators for Entity Search Engines [article]

Stefan Endrullis, Andreas Thor, Erhard Rahm
2010 arXiv   pre-print
Dynamic web applications such as mashups need efficient access to web data that is only accessible via entity search engines (e.g. product or publication search engines).  ...  However, most current mashup systems and applications only support simple keyword searches for retrieving data from search engines.  ...  We propose the effectiveness measure Coverage and its combination with an efficiency measure to assess the quality of query generators (Section 4).  ...
