4. The method according to claim 1 , further comprising: replacing the lexicon with a lexicon corresponding to a different subject in order to present for said indexing operation a different set of subject specific relevant objects.
1. A computer-implemented method of implementing a subject specific search engine to compile and access subject specific information, associated with a predefined particular subject, from a computer network, the method comprising: traversing links between websites comprising one or more objects on the computer network, by said search engine, the objects respectively comprising at least one of: one or more web pages comprising the websites; and one or more components comprising any one or more of said web pages, the objects comprising at least one of: words, terms or expressions; filtering, by said search engine, subject specific content of each said object visited to determine a relevance of said subject specific content thereof to said predefined particular subject, wherein said filtering comprises: (a) decomposing said objects into one or more said components; (b) receiving a lexicon, said lexicon comprising subject specific terminology deemed relevant to the predefined particular subject, the subject specific terminology comprising respective words, terms or expressions; (c) comparing said decomposed components of said objects to said subject specific terminology of the lexicon to determine whether each said object is a subject specific relevant object, wherein said comparing comprises: (i) assigning a weight to each of said words, terms or expressions comprising the subject specific terminology of the lexicon; (ii) if a said word, term or expression comprising the object matches a corresponding said word, term or expression comprising the subject specific terminology of the lexicon, adding a corresponding weight thereof to a cumulative total; and (iii) determining any of said objects to be a subject specific relevant object if the cumulative total surpasses a predefined threshold value; (d) based upon said comparing, determining all objects deemed to be subject specific relevant as objects to be saved; presenting for an indexing operation at said search engine, each object determined to be subject specific relevant to said particular subject based upon said filtering; indexing and storing said subject specific relevant objects in a searchable database; and assigning a word score to each word appearing on each subject specific relevant object; wherein said assigning a word score comprises: determining all websites found in the database that contain links to the website for each word on the websites, assigning a word score for that word based at least in part on its presence on each website containing a link to the website and increasing the word score for each website containing a link to the website when the word appears in close proximity to the link.
