Analysis of Signature Generation Schemes for Multiterm Queries In Linear Hashing with Superimposed Signatures
Can, Fazli; Ertugay, Osman (1995-12-01)Signature files provide efficient retrieval of data by reflecting the essence of the data objects into bit patterns. Our analysis explores the performance of three superimposed signature generation schemes as they are ... -
Analysis of Signature Generation Schemes for Multiterm Queries In Partitioned Signature File Environments
Aktug, Deniz; Can, Fazli (1993-05-01)Our analysis explores the performance of three superimposed signature generation schemes as they are applied to a dynamic sigrtature file organization based on linear hashing: Linear Hashing with Superinzposed Signatures ... -
Compressed Bit-sliced Signature Files An Index Structure for Large Lexicons
Can, Fazli; Carterette, Ben (1999-04-01)We use the signature file method to search for partially specified terms in large lexicons. To optimize efficiency, we use the concepts of the partially evaluated bit-sliced signature file method and memory resident data ... -
Concepts and Effectiveness of the Cover Coefficient Based Clustering Methodology for Text Databases
Can, Fazli; Ozkarahan, Esen (1987-12-01)An algorithm for document clustering is introduced. The base concept of the algorithm, Cover Coefficient (CC) concept, provides means of estimating the number of clusters within a document database. The CC concept is used ... -
A Detailed Stylometric Investigation of the İnce Memed Tetralogy*
Patton, Jon; Can, FazliWe analyze four İnce Memed novels of Yaşar Kemal using six style markers: “most frequent words,” “syllable counts,” “word type -or part of speech- information,” “sentence length in terms of words,” “word length in text,” ... -
Dynamic Signature File Partitioning Based on Term Characteristics
Aktug, Deniz; Can, Fazli (1992-08-01)Signature files act as a filter on retrieval to discard a large number of non-qualifying data items. Linear hashing with superimposed signatures (LHSS) provides an effective retrieval filter to process queries in dynamic ... -
Effectiveness Assessment of the Cover Coefficient Based Clustering Methodology
Can, Fazli; Ozkarahan, EsenAn algorithm for document clustering is introduced. The basic concept of the algorithm, Cover Coefficient (CC) concept, provides means of estimating the number of clusters within a document database and relates indexing ... -
Experiments on Incremental Clustering
Can, Fazli (1991-08-01)Clustering of very large document databases is essential to reduce the spacehime complexity of information retrieval. The periodic updating of clusters is required due to the dynamic nature of databases. An algorithm for ... -
Experiments on the Efficiency of Cluster Searches
Can, Fazli; Anderson, David (1991-03-01)The efficiency of various cluster based retrieval (CBR) strategies is analyzed. The possibility of combining CBR and inverted index search (11s) is investigated. A method for combining the two approaches is proposed and ... -
Experiments on Tunable Indexing
Can, Fazli; Ozkarahan, Esen (1988-04-01)The effectiveness and efficiency of an Information Retrieval (IR) system depends on the quality of its indexing system. Indexing con be used in inverted file systemsor in cluster-based retrieval. In this article, new concept ... -
HypIR: Hypertext Based Information Retrieval
Lee, Yuan; Can, Fazli (1992-08-01)Information Retrieval (IR), which is also known as text or document retrieval, is the process of locating and retrieving docri)nents that are relevant to the user queries. In hypertext environments, docuinent databases are ... -
Implementation of an Information Retrieval System (ANIRS) with Ranking and Browsing Capabilities
Can, Fazli; McCarthy, Kevin (1992-04-01)This report describes an implementation of a cluster based information retrieval system with statistical ranking facilities, ANIRS. ANIRS uses the vector space model to represent the document database. In this model, the ... -
Node Re-Usability in Structured Hypertext Systems
Abdalla, Omer; Can, Fazli (1992-08-01)When the size of a graph-based hyperdocument exceeds a certain limit, the graph structure gets complicated and causes navigation and document management problems. A simple solution for this problem is the structuring ofthe ... -
Signature File Hashing Using Term Occurrence and Query Frequencies
Aktug, Deniz; Can, Fazli (1992-08-01)Signature files act as a filter on retrieval to discard a large number of non-qualifying data items. Linear hashing with superimposed signatures (LHSS) provides an effective retrieval filter to process queries in dynamic ... -
Signature Files: An Integrated Access Method for Formatted and Unformatted Databases
Aktug, Deniz; Can, Fazli (1993-05-01)The signature file approach is one of the most powerful information storage and retrieval techniques which is used for finding the data objects that are relevant to the user queries. The main idea of all signature based ...
