DogPile is known as a best alternative of Google search engine. After its successful period in the 1990s (before Google dominated the search engine market) and some quieter years, Dogpile, the pack of dogs, is rediscovering its hunting instinct. In principle, DogPile combines information, links, images and videos from search engines such as Google, Yahoo, Bing and Yandex and offers features such as preferences or search filters for better “retrieval” results.
Can you imagine working on the Internet in a meaningful way without a search engine? Probably hardly. Ten years ago, on the other hand, there wasn’t even the word ‘search engine’ in the German language, and even today you won’t find it in the Duden or Brockhaus. However, in the reality of the internet, search engines like DogPile have seen a dramatic boost.
The Internet contains a gigantic amount of information, the largest that man has ever created. For this very reason, however, finding useful information is not an easy task. Imagine a pile of books in a library – hardly anyone would be able to find the book they want in a reasonable amount of time. Now imagine all the libraries in the world in one place. It looks something like this on the internet.
Without search engines, research tasks on the web would be doomed to failure from the outset. But even with these indispensable helpers, success is not guaranteed. Search engines have their pitfalls: either what you are looking for is not recorded or, conversely, the searcher is ‘overwhelmed’ by the amount of what is found.
Internet search engines are constantly struggling against the growth of the Internet. Because the WWW comprises around 5 billion pages, of which 7 million are added every day.
DogPile is same as Google Search Engine
There are several types of search tools, only the usual ones are described here, namely catalogs, search engines, and metasearch engines.
Catalogs in DogPile
A catalog is a human-made search offer. It is divided into categories and designed very clearly. Most of the time, a catalog is a list sorted alphabetically and according to criteria. The advantage of a catalog is that the pages are usually of very good quality because they are using a good technology for each search, as they are examined by the editors. In addition, the topics are very well divided. The disadvantage with catalogs is that they only take up a small part of the WWW and cannot keep up with the growth of the WWW.
Examples of some catalogs: Yahoo!, University of Hamburg page, …!
Search engines compared to DogPile catalogs are more complex. Search queries are handled by complex search algorithms. Then the search engine uses so-called robots that crawl the web pages and follow links. The search results are then arranged in databases. In order to get a successful result, Boolean search queries have to be made.
Boolean expressions are for example: “OR” and “AND”! The weighting of search results differs from search engine to search engine (search ranking). The search ranking is limited either to the number of visitors to the website or the importance of the links. The advantages of search engines can be viewed positively as well as negatively.
On the one hand, the search engines record more websites than catalogs, yet it is only 16 percent compared to the entire web. You can usually find the entered search term, but you will be overwhelmed by the mass of search results. What comes in addition to the constant www growth, is that much of the content of the websites is often out of date or they lead to dead links.
Examples of some search engines: Altavista, Google, Lycos, DogPile! There are now over 1000 search engines!
Metasearch in DogPile
If the user has still not managed to get a successful result, metasearch engines offer parallel searches. This means that they search several conventional search engines at the same time and then output a compiled search result. Each meta-search engine must contain 6 of the following 7 criteria:
- Parallel search (no all-in-one forms): The meta-search engine really has to search in parallel.
- Result merging: The results must be merged and presented in a uniform format.
- Duplicate elimination: Duplicate occurrences must be recognized and marked.
- At least AND and OR operators: At least the AND and OR operators must be available for logical operations.
- No loss of information: If a tracing service provides a brief description of the location, then this must be adopted.
- Search engine hiding: The specific properties of the search services under the meta-machine must not play a role in the operation, the user does not need to know anything about them
- Complete search: The meta-search engine should be able to search until one of the search engines below still returns hits.
One disadvantage of DogPile meta-search engines have is that they strike complex searches.
Examples of metasearch engines: Metacrawler!
Alternative search tools of DogPile
I have specified the following search tools here as alternative search tools, as you can give them search queries and get search results.
- Newsgroup: The newsgroup is a discussion forum where you can ask specific questions that other users can then answer. This is about the exchange of information that is limited to the knowledge of the user.
- Offline search engines: This is more of a metasearch engine that you can ask queries when operating offline, which then selects itself on the Internet when it is executed and searches several search engines at the same time and you will got the benefits than other who join the courses.
- Alexa: This program, if installed, shows all related links to the visited page. For more information, the Alexa website delivers more!
DogPile Future of searching
The future of searching looks like this:
- Face recognition with image search engines: This process has been used by the police for years to track down missing people on the Internet. The search engine notes features of the face (picture) and saves them in patterns. DogPile program that works by this method is the Duplicate Image Finder from Runningman Software
- Music search engines: This does not mean the search engines that look for MP3s such as Napster or Audiogalaxy, but search engines that can recognize special sound structures from pieces of music and thus track down music pirates.
- Search engines that also provide related topics: These are search engines that use the word: war; Issue topics like terror or peace at the same time.
- Intelligent search engines that act themselves: Search engines that are tailored to the user profile
