Method Detail

getScore

public double getScore()

Returns the relevance (rank) of the document in the context of given query. The relevance is used in our application scenario for ranked retrieval of query results; the best of them (e.g. top 10) are returned to the user. The document relevance is defined as the similarity between the document and the query (we use the scalar product between two feature vectors that represent the query and the document as the similarity metric).

Returns:

The relevance of the document in the context of given query.

getFeatures

public ISFeatureInterface[] getFeatures()

Returns the array of document-specific features. The features are pairs (term,weight) that are represented in our framework by objects that implement the interface ISFeatureInterface.

Returns:

The array of document-specific features.
