Synthesis Lectures on Information Concepts, Retrieval, and Services publishes short books on topics pertaining to information science and applications of technology to information. Query Expansion (QE) plays a crucial role in improving searches on the Internet. Here, the user’s initial query is reformulated by adding additional meaningful terms with similar significance. QE – as part of information retrieval (IR) – has long attracted researchers’ by:

Estimating the query difficulty is an attempt to quantify the quality of search results retrieved for a query from a given collection of documents. This book discusses the reasons that cause search engines to fail for some of the queries, and then reviews recent approaches for estimating query difficulty in the IR by: Get this from a library.
Estimating the query difficulty for information retrieval. [David Carmel; Elad Yom-Tov] -- Many information retrieval (IR) systems suffer from Estimating the query difficulty for information retrieval book radical variance in performance when responding to users' queries. Even for systems that succeed very well on average, the quality of results.
There has also been work on estimating query difficulty in the context of information retrieval [11, 49] to learn an estimator that predicts the expected precision of the query by analyzing the.

However, as many researchers observed, the prediction quality of state-of-the-art predictors is still too low to be widely used by IR applications. 3D Engine Design for Virtual Globes - Ebook written by Patrick Cozzi, Kevin Ring.

To improve the performance of your SQL query, you first have to know what happens internally when you press the shortcut to run the query. First, the query is parsed into a “parse tree”; The query is analyzed to see if it satisfies the syntactical and semantical requirements.

For example, a term frequency constraint specifies that a document with more occurrences of a query term should be scored higher than a document with fewer occurrences of the query term. Also, the retrieval algorithm may be provided with additional information in the form of Cited by: 1.
