What is authority and hub?
Authority and hub values are defined in terms of one another in a mutual recursion. An authority value is computed as the sum of the scaled hub values that point to that page. A hub value is the sum of the scaled authority values of the pages it points to.
How are the hubs and authorities ranked in HITS algorithm?
Jon Kleinberg’s algorithm called HITS identifies good authorities and hubs for a topic by assigning two numbers to a page: an authority and a hub weight. These weights are defined recursively. A higher authority weight occurs if the page is pointed to by pages with high hub weights.
What is the purpose of hub and authority in hyper induced topic search algorithm?
This algorithm is used to the web link-structures to discover and rank the webpages relevant for a particular search. HITS uses hubs and authorities to define a recursive relationship between webpages.
What is hub in data mining?
Data Mining Hub is a platform for the development of Data Mining and Machine Learning algorithms, which is based on iterative approach.
What are hubs and authorities?
Hubs and Authorities We now develop a scheme in which, given a query, every web page is assigned twoscores. One is called its hub scoreand the other its authority score. For any query, we compute two ranked lists of results rather than one. The ranking of one list is induced by the hub scores and that of the other by the authority scores.
What is hub score and authority score?
One is called its hub scoreand the other its authority score. For any query, we compute two ranked lists of results rather than one. The ranking of one list is induced by the hub scores and that of the other by the authority scores.
What is the difference between hub and authority pages?
In the computation we now develop, these hub pages are the pages that will emerge with high hub scores. A good hub page is one that points to many good authorities; a good authority page is one that is pointed to by many good hub pages.
