This kind of search agent can either collect pages from the Web on-the-fly or retrieve search results from other search engines (a process called meta-search).
Compared with the first approach, this method allows more computer processing time and memory to be allocated to the search process and more functionalities are possible.
The last module, called the phrase generation module, converts the words and associated part-of-speech tags into noun phrases by matching tag patterns to a noun phrase pattern established by linguistic rules.

The Web browser interface, through which the server-side search tool is accessed, is also more familiar to users.

Preservation of publications of historical interest for future access, obtaining knowledge about the preferences and interests of our society in the information age and intelligence gathering for security and protection are examples of national interests addressed by such system.
I believe that the implementation of a search engine specialised in providing services to community webs, such as tumba!, is a valuable alternative to global search engines for locating information within the Web pages of these communities.
presents results following the style that has been adopted since the first web search engines were created: output is in ranking order, through a filter that excludes from the listing those pages whose host is the same as in the previous result.

The correlations between similarity measures based on these cues and on semantic associations between pages is crucial in determining the performance of any search tool.
Lexical cues have traditionally been used by search engines to rank hits according to their similarity to the query, thus attempting to infer the semantics of pages from their lexical representation [29].
2 Since the majority of pairs occur near the origin, the same holds for most of the semantically related pairs, as shown by the high recall.
This creates an obvious challenge for search engines: achieving high recall costs dearly in terms of precision and leads to user frustration.

Project C1 is a censorship enumeration project that explores the relationship between censorship, technology and resistance through a technical analysis of state-imposed content filtering and blocking schemes illustrated through the identification of blocked URLs.
Highlight and support the growing resistance to Internet censorship that is occurring on the political, legal, and technological levels.
The People's Republic of China has implemented a national firewall strategy to block access to Internet content deemed "undesirable" or "subversive".
Civil society actors in China, particularly those working in the area of human rights, thus face significant constraints in their ability to collect information and communicate with the outside world via the web.
