Inverse Document Frequency and Web Search Engines

INTRODUCTION Full text searching over a database of moderate size often uses the inverse document frequency, idf = log(N/df), as a component in term weighting functions used for document indexing and retrieval. However, in very large databases (e.g. internet search engines), there is the potential that the collection size (N) could dominate the idf value, decreasing the usefulness of idf as a t...

Document Ranking and the Vector-Space Model

Using several simplifications of the vector-space model for text retrieval queries, the authors seek the optimal balance between processing efficiency and retrieval effectiveness as expressed in relevant document rankings. fficient and effective text retrieval techniques are critical in managing the increasing amount of textual information available in electronic form. Yet text retrieval is a d...

The ALVIS Document Model for a Semantic Search Engine

ALVIS researches the design, use and interoperability of topic-specific search engines with the goal of developing an open source prototype of a peer-to-peer, semantic-based search engine. Our approach is not the traditional Semantic Web approach with coded meta-data, but rather an engine that can build on content through semi-automatic analysis. This paper describes the ALVIS document processi...
