Find relevant documents for a given query in search process information seems a challenge for all models and techniques embodied in an information retrieval system. We continue this challenge by proposing a new measure of similarity between two queries. This similarity measure is based on two aspects: the first is statistical based on the statistic X2 (method CHIR) and the second is semantic based on the mutual information. Our proposed method shows its efficiency and performance according to tests performed on the standard corpus of research information CACM. © 2012 IEEE.

The objective of this work is the conception and the realization of a recommendatory system, using concepts of the web usage mining and being inspired by approaches to information filtering. This system includes a new hybrid method to rank documents web, in order to propose to the Webmaster (or admin) of platform e- learning the best available documents based of the historical to research done by learners. It is, actually a meta-search engine on the web, integrated into the e-learning platform to keep surfing traces of the learner during his searching. This will permit to have a usage basis that will be used by the system to help webmaster (admin) to make decisions about the documents to be added to the platform. The elaborated system will make it passible to propose help and assistance to learners of the platform. © 2012 Springer-Verlag.

Hybrid method for information retrieval based on the similarity between queries

International Review on Computers and Software 2012年第6期7卷 2960-2967页

Since its inception, the Web continues to grow in content and number of users. Despite improvements in the technology of search engines on the web, millions of users fail to meet their information needs. The use of models and methods of information retrieval seems a reasonable solution. This article presents a new measure of similarity between two queries. This similarity measure is based on two aspects: the first is statistical based on the statistic Χ2 (method CHIR) and the second is semantic based on the mutual information. Our proposed method shows its efficiency and performance according to tests performed on the standard corpus of research information CACM. © 2012 Praise Worthy Prize S.r.l. - All rights reserved.

The objective of this work is the conception and the realization of a recommendatory system, using concepts of the web usage mining and being inspired by approaches to information filtering. This system will propose to the Webmaster (or admin) from a platform for distance learning the best documents available on the web basis on the historical research done by learners. It is, actually a meta-search engine on the web, integrated into the e-learning platform to keep surfing traces of the learner during his searching. This will permit to have a usage basis that will be used by the system to help webmaster (admin) to make decisions about the documents to be added to the platform.

NAVAL ENGINEERS JOURNAL 1985年第4期97卷 279-286页

作者： BIONDI, RJ PRIDE, RW MURRAY, HD WHEELER, PK Roy J. Biondi:received his B.S.E.E. degree from the University of Illinois and has since taken additional graduate studies at the George Washington University. Currently he is head of the Communication Systems Application Branch code PDE 110–14 within the NAVELEXSYSCOM. Prior to his present appointment he served in the Combat Systems Division Naval Sea Systems Command and served as radar branch head in the former Naval Ship Engineering Center (NAVSEC). He was responsible for development and production of shipboard radars such as the AN/SPS-48 AN/SPS-49 AN/SPS-52 and AN/SPS-55. His primary Navy radar and combat system experience was attained during his earlier career in the Navy's Bureau of Ships where he was the AN/SPS-48 radar project engineer. In addition to ASNE which he joined in 1977 he is a member of IEEE and ASE and has had several technical papers published on radar radar antennas radar processing and transmission lines. Mr. Biondi has a total of 25 years naval experience in radar combat systems and communications. Richard W. Pride:received his B.S.E.E. from the University of Maine in 1959. Currently he is head of the Combatant Ship Section code PDE 110–143 in the Communications Systems Application Branch within the NAVELEXSYSCOM. Prior to joining the Naval Electronic Systems Command in 1974 he was the head of the Communication Antenna Design Section of the former Naval Ship Engineering Center. Harold D. Murray:received his B.S.E.E. from Vanderbilt University. Currently he is an EXCOMM program manager code PDE 110–1433 in the Combatant Ship Section of NAVELEXSYSCOM. As an EXCOMM program manager Mr. Murray is responsible for the external communications system design for the CG-47 (Aegis) class cruisers. Mr. Murray's previous government service includes 14 years at the Naval Research Laboratory (NRL) and 5 years at Naval Air Systems Command. Major areas of responsibility included shipboard RF distribution systems and aircraft intercommunication systems and control. Paul K. Wheeler:is pre

External communications is a critical element in the U.S. Navy design and utilization of a ship's combat system. The communications antenna system is a key factor in attainment of reliable circuit performance and reduction of electromagnetic interference (EMI). To maintain pace with improved ship manufacturing techniques and construction materials, along with design efforts to reduce topside generated EMI/RFI effects, an improved antenna design must also evolve. With the ever increasing complexity in the integration of the topside environment, the RF aspects of the antenna designs must be augmented by detailed analysis of the operating environment and the mechanical design if the goals of reliability and quality performance are to be achieved. The Naval Electronic systems command has developed a new “Broadband HF Communications Antenna.” This paper traces the design evolution and describes the processes in determining current design deficiencies, the design objectives to correct these deficiencies and the results obtained.
