Search engines leverage knowledge to improve information access. Such comes in different forms: unstructured (e.g., textual documents) and structured relationships between real-world objects topics). In order effectively knowledge, search should account for context, i.e., about the user query. this thesis, we aim support leveraging while accounting context. first part of study how make more acc...

There is no doubt that Search Engines are playing a great role in Internet usage. But all the top search engines Google, Yahoo and Bing are having a critical flaw called “Openness of a Search Engine”. An Internet user should be allowed to get the search results only when requested through Search engine’s web page but the user must not be allowed to get the search results when requested through ...

This paper compares the retrieval performance of seven public search engines on Thai queries by using a blind evaluation. Two of the engines used in this study are Thaifocused search services, while the remaining engines are large, commercial search engines that have wider collections of web data and support several languages. The results are compared by Mean average precision (MAP) and Mean re...

Web Usage Mining also known as Web Log Mining is the extraction of user behaviour from web log data. The log files also provide immense information about the search engine traffic at a website. This search engine traffic is helpful to analyse the ethics of search engines, quality of the crawlers, periodicity of the visits and also the server load. Search engine crawlers are automated programs w...

Empirical modeling of a number of different text search engines shows that the score distributions on a per query basis may be fitted approximately using an exponential distribution for the set of nonrelevant documents and a normal distribution for the set of relevant documents. This model fits not only probabilistic search engines like INQUERY but also vector space search engines like SMART an...

The World Wide Web (WWW) allows the people to share the information (data) from the large database repositories globally. The amount of information grows billions of databases. We need to search the information will specialize tools known generically search engine. There are many of search engines available today, retrieving meaningful information is difficult. However to overcome this problem ...
