Combining the HITS-based Algorithms with Relevance Scoring MethodsThe hub value and authority value are regulated in the way proposed in . If is the relevance score of a Web page and the hub value, instead of is used to compute the authority values of Web pages it points to. Similarly, if is its authority value, instead of is used to compute the hub values of Web pages that point to it.
We combine four relevance scoring methods, VSM, TLS, Okapi,
and CDR, with a HITS-based algorithm, respectively. In VSM,
cosine normalization is used to normalize the relevance scores to range
[0,1]. For popular topic, the relevance scores of the single term query,
such as blues, will be 1 for almost all the Web pages using both
and TLS. In this case, there is almost no difference between the
HITS-based algorithm and the combination the HITS-based algorithm with
or TLS. Next, we present the four relevance scoring methods and
how they are applied to the Web-based content analysis.
- Vector Space Model (VSM)
- Okapi Similarity Measurement (Okapi)
- Cover Density Ranking (CDR)
- Three-Level Scoring Method (TLS)
