Metacrawlers and Metasearch Engines - Search Engine Watch (SEW) Unlike search engines, metacrawlers don't crawl the web themselves to build listings. Instead, they allow searches to be sent to several search engines all at once. The results are then blended together onto one page.

Natural language user interface Natural Language User Interfaces (LUI or NLUI) are a type of computer human interface where linguistic phenomena such as verbs, phrases and clauses act as UI controls for creating, selecting and modifying data in software applications. In interface design natural language interfaces are sought after for their speed and ease of use, but most suffer the challenges to understanding wide varieties of ambiguous input.[1] Natural language interfaces are an active area of study in the field of natural language processing and computational linguistics. An intuitive general Natural language interface is one of the active goals of the Semantic Web. Text interfaces are 'natural' to varying degrees. Overview[edit] A natural language search engine would in theory find targeted answers to user questions (as opposed to keyword search). History[edit] Prototype Nl interfaces had already appeared in the late sixties and early seventies.[2] Challenges[edit] Modifier attachment Conjunction and disjunction

Bee Pollen Benefits As A Top 10 Superfood Bee pollen benefits rank as one of our top 10 superfoods and are one of our personal favorite power packed protein sources to add to shakes, smoothies and raw desserts. What is Bee Pollen? Essentially, is the male seed of flowers collected by our buzzing bee friends, the master pollinators of the earth! Millions of individual, high quality, golden granules are extracted from flowers by bees and joined together with a dab of honey they bring from the hive to create these small pollen pellets. A mixture of different pollens are used by the bees to provide a rich and balanced diet for the colony. Research has shown that one pound of pollen usually supplies 4,500 bees for one year. The bees join the grains together with honey, along with their own digestive enzymes. They are brought back to the entrance of the hive where the collection trap is located.

Les opérateurs booléens A l'aide des "opérateurs booléens" : ET, OU, SAUF vous avez la possibilité de combiner entre eux deux termes de recherche - ou plus - à l'intérieur d'un champ et entre les champs). Cela permet de trouver des enregistrements contenant deux mots spécifiés ou plus, un mot mais pas l'autre ou tous les enregistrements contenant un, plusieurs ou tous les mots spécifiés. Les opérateurs booléens ET, OU, SAUF peuvent être saisis dans le formulaire de recherche sous forme de mots ou de symboles : Les opérateurs booléens entre les champs de recherche Chaque champ du formulaire de recherche est connecté aux autres champs par un opérateur booléen. Les opérateurs booléens utilisés pour relier les champs sont : OU - s'utilise pour trouver des enregistrements avec des termes provenant d'un champ ou de l'autre.ET - s'utilise pour trouver des enregistrements avec des termes à partir des deux champs.SAUF - s'utilise pour trouver des enregistrements avec des termes du premier champ mais pas du deuxième.
What Is A Meta Search Engine & How It Works? [Technology Explained] Search engines are an integral part of the Internet. Could you imagine the Internet without Google? And I am not even talking about all the services that Google offers as a company. Just imagine the Internet without Google search and you will realize how important search engines are. The Internet has billions and billions of websites with loads of content but it’s the search engines that make them discoverable. So is there any difference between search engines and meta search engines? Before I even attempt an explanation, let me tell you that search engine technology is one of the most well kept secrets of computer science. What is a Meta Search Engine? To understand what a meta search engine is, first you have to understand how a search engine works. So now back to how a meta search engine works. Are Meta Search Engines Better? Let me explain with an example. I say so because the index of search engines are more or less the same. Example Of Meta Search Engines
How Google Works If you aren’t interested in learning how Google creates the index and the database of documents that it accesses when processing a query, skip this description. I adapted the following overview from Chris Sherman and Gary Price’s wonderful description of How Search Engines Work in Chapter 2 of The Invisible Web (CyberAge Books, 2001). Google runs on a distributed network of thousands of low-cost computers and can therefore carry out fast parallel processing. Googlebot, a web crawler that finds and fetches web pages.The indexer that sorts every word on every page and stores the resulting index of words in a huge database.The query processor, which compares your search query to the index and recommends the documents that it considers most relevant. Let’s take a closer look at each part. 1. Googlebot is Google’s web crawling robot, which finds and retrieves pages on the web and hands them off to the Google indexer. 2. Googlebot gives the indexer the full text of the pages it finds. 3.
Creating A Website Data Report: Three Degrees Of Separation Advertisement Having a comprehensive data report about your website is like having a Rosetta Stone to guide your decision-making process over the lifetime of the website. A powerful report combines data gathered from a variety of sources, including observation of and interviews with users, and analysis of the website’s analytics. The goal is to put the key insights from your research of a website into a single document. A well-rounded report is built with a combination of data gathered from three sources: personal (qualitative research), community (quantitative research) and network (website analytics). We’ll create a data report for our fictional Widgets website. Gathering Personal Data (Qualitative Research) The key to getting qualitative data from users is to observe them as they use the website. To understand their thought process and experience their frustrations, have the user talk through what they are doing as you take notes. Reaching Out To The Community (Quantitative Research)
